    Technical area
    The subject of the invention is an electrical switch provided with a control device of the operating mode for an actuator of said electrical switch.
    He perfected some devices among which that described in EP-A-1 659 601, which is referred for further details. The electrical switch has a fixed contact, a movable contact and a grounding contact; a movement of the moving contact, normally produced by a motorized actuator, makes it possible to switch it between an open state, a closed state and an earthed state. The motorized actuation must, however, be replaced by manual actuation in certain special situations and when a failure occurs. It is then necessary to guard against switching errors, and the actuator must be substantially complicated: the usual mode, allowing unconstrained switching between the three states, is prohibited and must be replaced by two limited switching modes, one between closing and opening, and the second between grounding and opening.
    The actuator is then enriched with a mode selector manipulated by an operator and which comprises, in the above-mentioned document, three service positions corresponding to the motor-controlled, non-restrictive switching mode and to the two switching modes limited to manual actuation; the selector comprises a movable stop element, comprising two stops respectively engaging with a complementary element belonging to the main transmission during the limited switching modes to stop its movements when a stop state is reached, but completely releasing this complementary element during the unconstrained switching mode. The mechanisms of the actuator are extensively described in the aforementioned document and are not modified with the present invention, except for a few details; therefore, their detailed description will not be repeated here.
    The selector must not only allow switching from one switching mode to another, but be provided with safety devices to prevent erroneous or untimely maneuvers, especially manual actuation. In the previous document, the selector lever is a movable lever in front of a support wall and the selector further comprises a stop pin removably engaged in an orifice made through this wall and prohibiting, as long as it is installed, passing through the hole of a crank used to accomplish manual actuation. The locking pin may be attached to the lever by a padlock so as to maintain the lever is in front of the orifice of the wall or on one side or the other of it, which corresponds to the three service positions of the selector and at the three main positions of the stop element; it is then itself retained in the hole by the padlock and therefore prevents manual actuation even when the lever is at a position corresponding to this actuation; only motorized actuation is possible. The stop pin can also be placed by being more recessed in the hole so as to mate with the crank shaft located behind the wall, to block and prohibit any actuation, even motorized. It must be admitted, however, that these safety devices are rudimentary; it is still unfortunate to have three operating modes only, which has led to reserving the switching modes limited to manual operation; however it could have been interesting to apply the motorized actuation to these modes too.
    The object of the invention is to improve the selector of the actuator in these aspects by allowing orders of operating procedures both more numerous and safer to make it compatible with a large amount of security concepts. , and to offer more possibilities of mode exclusion for certain positions of the selector, by mechanical interactions. In general form, the invention relates to an electrical switch having a control device for operating an electric switch actuator having a closed state, an open state and an earthed state, the actuator comprising a motor for motorized actuation of the switch, a crankshaft for manually operating the switch and a main transmission connecting the shaft and the motor to a movable contact of the switch, the controller enabling a mode of operation of the switch unconstrained switching mode, a first limited switching mode, between closing and opening, and a second limited switching mode, between the grounding and the opening, and comprising for this purpose a selector comprising a movable handle in front of an orifice of said wall of the switch for introducing the crank to the shaft, the control device being characterized in e that the selector has five service positions, two of which for each of the limited switching modes, the selector comprising a discriminator device which, for each of the limited switching modes, respectively reserves one of said two service positions only to the motorized actuation and another of said two service positions only for manual operation.
    The invention thus offers two service positions and two additional operating modes, corresponding to the two limited switching modes and the motorized actuation. This gives a complete possibility of using the actuator between the unconstrained switching modes and the limited switching modes on the one hand, and between the manual actuation and the motorized actuation on the other hand, since only 1 Motorized actuation, which does not allow switching errors, is useful in the unconstrained switching mode. The discriminator device prohibiting one of the actuations at one of the positions of each of the limited switching modes offers a particular security when these positions are chosen, whereas the known device had the only stop pin, usable elsewhere in all positions and which was easy to remove, to prohibit manual operation.
    It is still possible and advantageous in improved embodiments, that each of the two positions of each of the limited switching modes is reserved for a single actuation, one manual actuation and the other motorized actuation : the operation is even safer.
    The invention is applicable to devices of the kind of figs. 1 and 2, wherein the selector includes a stop member located behind the wall and a selector transmission extending between the selector and the stop member, the handle and the stop member taking a plurality of service positions. defining the switching modes, the stop element comprising two stop assemblies respectively engaging a complementary element belonging to the main transmission to the limited switching modes, but the stop element being completely disengaged from the element complementary to the unconstrained switching mode; it is also applicable to other selectors, based for example on electrical controls to allow manual actuation or motorized actuation, as appropriate.
    In a particular embodiment, the selector comprises a solid portion of the discriminator device, at least partially covering the orifice of the wall for only one of said two positions of each of the limited switching modes, so as to reserve the position in question to motorized actuation by preventing an introduction of the crank to the shaft. This full portion belonging to the selector associates certain service positions with a specific actuation, which the independent stop counter did not do.
    The handle may consist, instead of the lever used in the aforementioned document, a movable plate groove scrolling past the wall opening when the plate is moved, the groove comprising portions of a first width and of a second width, the first width being smaller than a diameter of the orifice and the portions at the first width coming in front of the orifice at the positions corresponding to the motorized actuation, the solid portion mentioned above thus belonging to the plate , the second width being greater than the first width and allowing the introduction of the crank, the portions of the second width coming in front of the orifice at the positions corresponding to the manual actuation.
    The controller then itself serves to carry the full portion used to distinguish the motorized actuation of the manual actuation in each of the limited switching modes; it can also help to distinguish conveniently the service positions if it includes recesses and covers symbols corresponding to modes and actuations, the recesses discovering the only symbols corresponding to each of the service positions when they are respectively reached.
    The plate may consist of a disc rotating about an axis, which gives a moderate size of the handle on the wall.
    The solid portion may still belong to a selector disk located behind the wall, mounted on the axis and of variable diameter, rather than the outer handle.
    The device may further comprise a stop pin removably disposed through the wall orifice. In connection with the devices where the selector comprises a groove plate of two different widths comprising the solid portion, it is advantageous for the stopper to comprise a long portion, limited by a coupling end to the shaft and a shoulder. support on the wall, a portion of the stop pin (separated from the long portion by the shoulder) being capable of interfering with the solid portion when the long portion is disposed in the wall opening: when the pion d The stop is coupled to the shaft so as to block the transmission, it is then impossible to switch to motorized operation and thus risk damaging the pin or the shaft. It is further advantageous for the stopper to comprise a short portion (possibly opposite to the preceding one, the stopper being reversible then), limited by a free end and a support shoulder on the wall, a portion of the stop pin (separated from the short portion by the shoulder) being able to be retained between the solid portion, having penetrated into the groove, and the wall, when the short portion is disposed in the wall opening: the Stopper can not be removed from the port until the service positions corresponding to manual operation are reached.
    The device may be provided with various locking means with or without the stopper. The plate can first have a border next to the groove and has locking holes associated with the service positions. These holes can be occupied by a padlock loop in cooperation with a locking hole passing through the stop pin and in front of which the border scrolls (the plate then being maintained at one of the service positions by the stop pin engaged in the orifice of the wall); or a locking hole of a fixed ear standing on the wall, in front of which the border scrolls (the plate then being locked directly to the wall). Other locking means include plugs insertable into the wall through notches in the plate when the service positions are reached; or a disk with holes located behind the wall, the latter carrying a lock whose bolt penetrates into the holes when the service positions are reached.
    Such locking devices can be used redundantly. It should be noted that if several are used simultaneously, the locking functions may be different. In particular, it is possible to use holes in the form of elongated notches embracing two service positions, each associated with the same limited switching mode and, respectively, with manual actuation and motorized actuation. Such notches may be associated with another locking means, which includes separate holes for each of the service positions. When both locking means are used at one time, the selector is maintained at a single service position; when the second locking means is raised, the selector can switch from manual operation to motorized operation or vice versa, but it remains retained in an invariable switching mode as long as the first locking means is maintained.
    Other discriminator devices may use electromechanical means. Thus, the selector may comprise a transmission leading to a power supply interruption device of the motor, so as to forcibly remove the motorized actuation when a position of the selector corresponding to a manual operation is reached. Or alternatively, a shutter located behind the wall, controlled by an electromagnet, can be placed and kept in the closed position at a rest state of the electromagnet, the rest state only ceasing when one of the service positions corresponding to the manual operation is reached and a button is pushed. Manual actuation becomes possible only by the voluntary action of the button push operator. The shutter has a role of shutter of the crank similar to that of the full portion of the joystick mentioned above.
    It is pointed out that the movements of the selector between the service positions corresponding to the same limited switching state do not necessarily involve movements of the movable stopping element of the transmission. This can be achieved if, for example, the selection transmission comprises a cam moved by the selector and comprising an oblique central portion, between two service positions respectively corresponding to the limited switching modes and to the motorized actuation, and uniform extreme portions, extending respectively to the above service positions and the service positions corresponding to the limited switching modes and the manual operation.

    We first briefly recall the general configuration of the system by means of FIG. 1. An electrical switch (1) comprises a fixed contact (2), a movable contact (3) and an earthing contact (4) which is a second fixed contact. An actuator (5) moves the movable contact (3) to bring it to an open state where it is separated from the other two, or to a closed state or an earthing state in which it contacts respectively the fixed contact (2) and the contact of the earthing (4). The actuator (5) contains a main transmission (6) composed mainly of a multi-stage gear for moving the movable contact (3) by a motor (7) in ordinary circumstances or by a shaft (8) in manual control circumstances. The shaft (8) is directed to an orifice (9) of a wall (10) of the actuator (5) and can be engaged by a crank (11) engaged in the orifice (9). A selector (12) is added and comprises a handle (13) movable on the wall (10) in front of the orifice (9) and causing a selector transmission (14) which ends on a stop element (15) adapted to interact, according to its position, with a complementary element (16) of the main transmission (6) to limit the movement thereof and the movable contact (3).
    Some additional details are given in FIG. 2. The stop member (15) comprises a ring (17) provided with two internal teeth (18 and 19) and a lever (20); it can rotate about an axis (21) opposite this lever (20), whose end is retained in a groove of a guide rail (22) and moved in this rail by a rod (23) hinged to another lever (24) rotated by the handle (13). The ring (18) surrounds a cam (25) provided with two teeth (26 and 27) which accompanies a toothed stage of the main transmission (6) by rotating about an axis (28) in an angular extent of less than 360 ° . In a middle position, no contact is possible between the ring (17) and the cam (25), and the movement of the main transmission (6) is not impeded; in the position shown here, where the lever (20) is pushed to an extreme position to the left, the movement of the main transmission (6) is stopped as soon as the tooth (27) touches the inner tooth (18); in an opposite position of the lever (20), which is not shown, the movement of the main transmission (6) would likewise be stopped by contact between the other teeth (19 and 26) at another position of the main transmission (6). Two different modes of limited switching are thus obtained in which the displacement of the movable contact (3) towards the fixed contact (2) or the earthing contact (4) is forbidden as the case may be, thus allowing it only a limited commutation. A mechanism not shown (such as the pin (48) of EP-A-1 659 601 or a particular form of the opening of the ring (19) in cooperation with the shape of the cam (16) still allows to limit the movement of the selector (12) according to the position of the stop element (15) and thus to avoid manual incorrect commutations of the selector (12).
    The following figures illustrate the selector (12) and particularly the handle (13) and the neighboring parts. Referring, for example, to FIG. 3, the handle (13) mainly comprises a disc (29) mounted on the wall (10) and rotating about an axis (60) passing through this wall. The disk (29) is cut with a circular groove (34) extending over a lower circle sector about the axis (60), two lateral openings (31 and 32) and a depression (33). higher. The orifice (9) opens out in front of the groove (34); it is here, as often blocked by a stopper (35) described below. The wall (10) carries symbols (30) of switching modes and operating modes, one of which is respectively revealed by the lateral openings (31 and 32) when the operating positions of the selector (12) and the disc (29) are reached. The wall (10) further comprises bores in front of which the upper depression (33) is respectively located at each service position and wherein a locking pin (36) engages, the locking pin (36) being spring-loaded through the disc (29) and thereby occupying the holes in the wall (10) as soon as it is in front of them. It is a first means of preventing rotation of the disc (29) to move to another service position as soon as it is installed.
    The disc (29) comprises a border (37) extending at the periphery, around the groove (34), but on a larger sector of angle and which is provided with holes and notches that will be described below. The border (37) runs in an ear (38) mounted on the wall (10) and which is also pierced. The groove (34) has a central portion (39) having a first width and two end portions (40 and 41) having a second greater width.
    The states of the selector (12) will now be described using FIG. 3 and following figures. Fig. 3 illustrates the selector in a median position, where the orifice (9) is in the center of the groove (34): this position corresponds to a middle position of the stop element (15), and to the switching mode without characteristic stress of normal operation for which the motorized actuation is perfectly suitable. Symbols corresponding to the possibilities of switching to the closed state and to the grounding state are visible at the bottom of the lateral opening (31), and the symbol of a motorized operating mode appears at the bottom the other side opening (32). However, if the selector (12) is moved in either direction by a moderate amount so as to place the orifice (9) at one end or the other of the central portion (39) of the groove (34) (Fig. 4 or 5), one of the limited switching modes is controlled as appropriate, and a symbol showing only the closing of the contacts or the earthing appears at the bottom of the lateral opening (31). , depending on the case; another motorized actuation symbol still appears in the other lateral opening (32).
    If the disc (29) is rotated in larger amounts, the orifice (9) is found in the end portions (40 or 41) of the groove (34) (Fig. 6 or 7). The same limited switching states as in fig. 4 and 5 respectively remain and identical symbols continue to appear in the first lateral opening (31); but the manual actuation symbols now appear in the other lateral opening (32), which means that these disk positions (29) are designed for manual driving of the main transmission (6). There is shown a state of the device during which manual control is undertaken in FIGS. 6 and 7: the crank (11) is pushed into the orifice (9) after the stop pin (35) has been withdrawn, and it can then be rotated to drive the shaft (8).
    These figs. 3 to 7 show that the width of the end portions (40 and 41) of the groove (34) is greater than the diameter of the orifice (9), while the width of the central portion (39) is smaller. This smaller width is chosen to place solid portions (48) of the disk (29) corresponding to the borders of the central portion (39) between the first width and the second width of the groove (34) in front of the hole ( 9) and thus to prevent the introduction of the crank (11) to the service positions of Figs. 3, 4 and 5 corresponding to a motorized actuation, even if the stopper (35) is removed: this is a first precaution to prevent incorrect operation of the actuator (2).
    The stopper (35) appears completely in FIG. 8. It essentially comprises a central portion (42) wider, a short side (43) and a long side (44) pointing from the central part in opposite directions. Each of these sides (43 and 44) can be engaged through the orifice (9), but the central portion (42), being wider than it, remains outside. When the long side (44) is engaged, its end engages that of the shaft (8) at the extreme depression, when a shoulder (45) of the central portion (42) abuts against the wall (10) . The engagement can be achieved by a wide-end yoke end (84) which engages a drive rod (85) transverse to the shaft (8): the stop pin (35) - If it is fixed to the edge (37) by a padlock (54) described below - then blocks the shaft (8) and therefore any movement of the main transmission (6) and the actuator (2). When the short side (43) is engaged in the hole (9), no coupling with the shaft (8) is possible and it is free to move with the rest of the main transmission (6) . The stopper (35) then only serves to close the orifice (9) by preventing the introduction of pollutants or the crank (11); it is the state which is represented in fig. 3 to 5.
    It should be noted in this regard that the central portion (42) is provided with a groove (46) close to the shoulder (47) connecting the short side (43). This arrangement allows, when the short side (43) is pressed into the orifice (9), to pass the solid portion (48) of the disk (29), the central portion (42) being wider than the first width of the groove (34) but less than its second width (that of the end portions (40, 41)). It follows from this construction that the depression of the stop pin (35) by the long side (44) in the orifice (9) is possible only, as well as the blocking of the main transmission (6), when the selector is in the extreme positions of fig. 6 and 7: the motorized actuation can thus be blocked by the stopper (6), but only when a manual actuation mode has been ordered, since the motorized actuation would then be activated accidentally and incorrectly and that it could be dangerous; in addition, an interference between the solid portion (48) and the central portion (42) appears as soon as the disc (29) is rotated, so that one can not return immediately to the motorized actuation. In contrast, when the locking pin (35) has been depressed with the short side (43) in the orifice (9), it is retained by engagement of the solid portion (48) in the groove (46). in the positions of fig. 3, 4 and 5, covering a peripheral portion of the central portion (42), that is to say that the removal of the stop pin (35) and the possibility of introducing the crank (11) exist only when manual operation has been ordered.
    The locking pin (35) carries seals (49 and 50) under the shoulders (45 and 47) to close the orifice (9) tightly when it is installed. It finally includes two holes (51 and 52) which cross it transversely. The ear (38) likewise comprises a hole (53) visible in particular in FIG. 4, the crossing, and the border (37) other holes, visible in FIG. 9.
    These holes of the border (37) can be used for locking devices with the holes (51 and 52) of the stop pin (35) where the hole (53) of the ear (38), in engaging respectively padlock loops (54 and 55) in various figures. Fig. 9 shows that the border (37) comprises two holes distributed over two circles (V and W) at different heights: the first circle has two holes in notches (56 and 57) elongate and a circular hole (58) between the two notches , while the other circle (V) comprises five circular holes (59) (all not shown in the figure). The notches (56 and 57) and the circular hole (58) cooperate with the hole (53) in the ear (38) and the padlock (55), while the holes (59) of the other circle cooperate with the hole (51 or 52) of the stop pin (35) (depending on the direction of its depression) and the padlock (54).
    The engagement of the locks (54 and 55) locks the disk (29). The presence of five cylindrical holes (59) on the circle (V) makes it possible to lock the disc at each of the service positions by using the stop pin (35) and the padlock (54). In this embodiment of the invention, the cylindrical hole (58) likewise locks the disc at the middle position corresponding to the normal operation of the actuator (2), using the bore (53) and the padlock (55) , but the notches (56 and 57) elongated allow only incomplete locking when the lock (55) is engaged, since one can then oscillate between the motorized actuation and the manual actuation inside one either of the limited-switching modes, which allows additional maneuvering possibilities without the risk of producing incorrect switching.
    Depending on the circumstances, one or other of the locking mechanisms, or more of them, may be used; figs. 3 to 7 illustrate the use of one or the other padlock (54 and 55) (the latter being however only usable when the stopper (35) has been removed, but the use of the padlock (54) ) and the stop pin (35) remains possible in the positions corresponding to manual operation as shown in Fig. 8).
    [0033] Certain other aspects of the invention will now be described. Fig. 10 illustrates that the axis (60) of rotation of the disc (29) carries, behind the wall (10), a locking disc (61) provided with notches (62) into which the bolt (63) can enter. a lock (64) controlled by a key (65) extending in front of the wall (10) beside the disc (29). This is an additional locking device that can be used in redundancy with the previous ones; the notches (62) may correspond, in a similar manner to the holes and notches previously encountered, to interlocks at only one of the service positions, or to several of these positions, permitting switching from one to the other. The axis (60) still carries a disk (66) provided with a cam (67) (here in the form of a groove) which causes the rotation of the lever (24) for driving the rod (23), the lever ( 24) being of triangular shape and articulated on the housing of the actuator (2) by a fixed axis (68). Fig. 11 shows that the cam (67) comprises two uniform (constant radius) end portions (69 and 70) and a central portion (71), also of constant radius, these three portions being separated by two variable radius transition portions: the counter-cam of the lever (24) is engaged in one or the other of the uniform end portions (69 and 70) during the limited switching modes each comprising two of the service positions, so that the movement of the selector (12) between the manual actuation and the motorized actuation of each of these limited switching modes does not cause displacement of the stop element (15), which remains in engagement with the complementary element (16). ). The stop element (15) also remains stationary when the cam follower (24) passes through the central portion (71), which corresponds to the passage of the selector (12) by the position of FIG. 3. The movement of the stop member (15) occurs only when the cam follower (24) passes through the transition portions which correspond to the passages between the limited actuation modes and the unconstrained actuation.
    FIG. 10 further represents a rod (72) articulated to a lever not shown but rotating with the axis (60) and which leads to a switch (73) of the power supply (74) of the motor (7). This device is shaped so that the switch is open when the selector (12) reaches extreme service positions corresponding to the manual operation: inadvertent control of the motor becomes impossible.
    Finally, we refer to FIG. 12. The device may further comprise a shutter (75) located behind the wall (10) so as to cover or unmask the orifice (9) as the case may be. The shutter (75) is controlled by an electromagnet (76) which is however generally at rest and by a spring (77) which holds the shutter in a closed position of the orifice (9).
    The excitation of the electromagnet (76) which moves the shutter (75) to unmask the orifice (9), occurs when two following conditions are met: a push button (79) is pushed , and the selector is placed in a manual operation mode: two switches are then closed at a time to produce this excitation: it is then possible to introduce the crank (11). The shutter closes when the pressure on the push button (79) stops. The switch dependent on the selector (12) can be controlled by a mechanism similar to that of the switch (73) of FIG. 10, or by an autonomous central control device (80) whose function is to make the manual operation possible depending on the switching state or the operating state of the high voltage substation. The push button (79) is optional and can be omitted.
    The discriminator device comprising the connecting rod (72) and the switch (73) is complementary to those which have been mentioned so far and comprising the solid portion (48) or the shutter (75), since it is forbidden the motorized actuation at the positions provided for manual operation, while the previous devices prohibit manual actuation to the positions provided for the motorized actuation: these two kinds of devices can therefore favorably be associated on the same actuator.
