    and two confirmation breakers, respectively, installed in series in the supply circuit of the two windings 15 of two electromagnets. These two confirmation breakers are driven by a transmission system incorporating two coaxial rotary shafts, which are end-to-end and fitted with each lever.
    configured in such a way that it is turned by one of the electromagnets and with a finger interacting with the confirmation switch of another electromagnet 4. The invention, in particular, makes it possible to increase the safety of a reversible switch of the contactor type. 4 hp f-ly, 5 ill.
    This invention relates to protected contactor-type reversing switches using a multifunctional transmission system for controlling confirmation interruptors.
    It is known that reversible switches of a contactor type usually have inside a common casing two systems of identical contactors with two electromagnets, whose measles drive two sets of phase switches, the inputs and outputs of which are interconnected by means of two communication circuits.
    The general principle of such a contactor type reversing switch is well known and not described in detail, it being understood that one of two electromagnets is excited in working condition, and the reverse is provided by interrupting the power supply by the electromagnet that was excited and powering the other electromagnet that was previously turned off condition.
    These contactor-type reversing switches are protected against overload and long-term overloads by a common protective circuit including a magnetic protective device, using one magnetic starter for each phase switch, through which current passes through the winding. passing through this switch and a thermal protection device including bimetallic thermometers installed in the phase circuits located behind the output connecting circuit. Typically, these two protective devices operate in such a way as to cause the quick opening of the complex of the phase switches using the potential energy release mechanism due to one of the two current anomalies mentioned earlier.
    The effect of the presence of connecting circuits to a common short circuit of the network.
    Such protection in some cases is complemented by the use of confirmation interrupters installed in series in the power supply circuit of the coils of two electromagnets, which are actuated to ensure the disconnection of the power supply circuit of the electromagnet, which is not excited, and thus exclude the possibility of simultaneous excitation of two electromagnets, for example due to an erroneous command.
    This invention relates to reversible
    5 a contactor type switch, in which actuation of the confirmation breakers is performed by a multifunctional transmission system which can provide, besides the function
    0 acknowledgments, other security features that may trigger the opening of one or two acknowledgment interrupters.
    According to the invention, this transmission system contains two coaxial rotating
    5 shafts located second and each provided with a radial lever that can be rotated in one direction by the core of the corresponding electromagnet, the first finger or the like,
    0 which protrudes in the radial direction in order to interact with the confirmation switch of another electromagnet to open this confirmation iipe gate at the end of the turn in the indicated direction, and at least with a burning finger or similar element that protrudes in the radial direction so that it could be set in motion by a triggering organ of the protection device, with the two electromagnets arranged side by side and possessing two moving crusts that can be moved parallel flax in a certain direction.
    the power adjacent to this electromagnet and the corresponding rotary shaft so that the fingers of this shaft can be actuated.
    For this, one of the rotary shafts has a radial pin cooperating with the second rotary shaft. The lever associated with the first rotary shaft is attached to the free end of said finger. This arrangement allows one to act in such a way that the lever rigidly connected to the rotary shaft, located on one side of one of the electromagnets, interacts with the core of the other electromagnet.
    It is desirable that each confirmation breaker has a fixed contact element mounted on the frame of the electromagnet coil associated with it, and a movable contact element consisting of a flexible plate, the first end of which interacts with the fixed contact element and the second one is fixed on the box cover so that the removal of said cover would lead to the opening of the supply circuit of said winding. The first end of this flexible plate extends past the stationary contact element so as to interact with one of said first fingers.
    In addition, said second fingers may be positioned adjacent to each other in order to ensure that they are exposed to the general actuation organ provided for the simultaneous opening of two confirmation interrupters.
    FIG. 1 is a schematic diagram of a contactor type reversing switch in a protected version; Figs. 2 and 3 show two schematic longitudinal sections of a reversible switch of a contactor type, these two sections showing the principle of the mechanism associated with two electromagnets of a reversing switch of a contactor type: in Figs. 4 is a partial cross section of the reversing switch of the contactor type shown in FIG. 2 and 3, this section passing through the common axis of the actuation shaft of the confirmation interrupters; in fig. 5 is a schematic perspective view of mechanisms linking two electromagnets.
    magnet 4 (5), the bore 6 (7) of which drives the set of switches. Phases 9, 10, 11 and 12, 13, 14, and the windings 15 and 16 can be energized using a remote control circuit connected to the BI terminals , BI, B2, B2.
    On the input side of the RST network, the breakers 9-14 are connected respectively to the three common input terminals 18, 19 and -20 and interconnected by the first bundle FI of connecting conductors FR, FS, FT.
    The outputs of the choppers 9-14 are connected respectively to the three input terminals 31, 32 and 33 of the common protection circuit (block 27) through the second bundle F2 of the connecting conductors F2, F2, F2, and three outputs of this circuit 27 are connected to the engine.
    The common protective circuit contains connected in series between each pair of inputs 31, 32. 33 and outputs 24, 25, 26 a thermal switch in the form of a bimetallic element 34, 35, 36, operating with continuous current overload, and a magnetic switch ZOa, ZOV, 30s, sensitive to short-circuit currents.
    These switches, both thermal 34, 35, 36 and magnetic ZOA, ZOOS, 30s, act (connections LI, L2) on the shut-down organ 37 of the spring-type shutdown mechanism 37, equipped with a manual control member 38, which acts in one direction on interrupters 9-14 through the transmission organ (shown in Fig. 1 by UB, dashed lines). The shutdown mechanism 37 is designed such that it causes a sharp and simultaneous opening of the choppers 9-14 when one of the current anomalies is detected.
    In addition, switching off the mechanism 37 causes the simultaneous opening of two confirmation interrupters h, l2, connected in series with the windings 15 and 16 of electromagnets 4 and 5 (connection 40 by dashed lines).
    The reset to the initial position of the mechanism 37 is provided either by the manual reset to the initial position 38, or by a remotely controlled auxiliary return box 39.
    Maneuvering unit 38 can be manually set (or using a remote-controlled box) to its original position 0. which causes the simultaneous opening of the interrupters h, 12, or to the cocked position A (Auto), which causes them to close when thermal equilibrium conditions are established.
    open one of the two contactor systems when the other is closed.
    In addition, this locking is duplicated by electromagnetic locking, which involves two mechanical connections 42 and 43, each of which connects pin b and 7 of one of electromagnets 4 and 5 to the confirmation interrupter I, 12 connected to coil 15 and 16 of the other electromagnet 4 and 5, and these connections 42 and 43 are made so that the closing of one of the electromagnets 4 and 5 causes the opening of the supply circuit of the coil 15 and 16 of the other electromagnet 4 and 5,
    In the example shown in FIGS. 2--5, the reversible switch of the contactor type is made in the form of three modules (interrupt module Mi, direct control module M2 and indirect switching module Mz),
    The interrupt module Mi has inside the box 46 two switching complexes, each of which has a polar interrupter 9-11 and 12-14 located adjacent to each other, of which only two interrupters 9 and 12, corresponding to these complexes, are shown in FIG. . 2 and 3.
    The normally closed type breakers 9-14 each have two fixed contact elements 48 and 49 fixed to two conductors 50 and 51. connected to two connectors 52 and 53. a movable set consisting of a movable contact carrier 54 of electrically conductive material which has two movable contact elements 55 and 56. designed to interact with stationary contact elements 48 and 49, arranged to maneuver, consisting of a pusher 57, made of electrically insulating material, rigidly connected with nym contact holder 54, a spring 58 disposed between the support wall 59 of the box 46 and the movable contact holder 54 so that the spring force presses the movable contacts 55 and 56 to fixed contacts 48 and 49,
    Box 46 has an elongated parallelepiped shape and opposite the supporting surface 59 an assembly surface 60. El of the middle part of which is a transverse partition 61, Transverse partition 61 divides the assembly surface 60 into two zones Li, L2, for receiving a forward switching control module M2 and the indirect switching control module M3. It has (from the side of the assembly zone Zi) a floored profile, and from the side of zone 2.1 it has a flat surface F. perpendicular to the surface 60 of the assembly.
    The zone Z2 has in the vicinity of the partition 61 six openings O, which are made along a line perpendicular to the plane of FIG. 2 and 3 through which the followers 57 of the six interrupters 9-14 pass.
    A direct switching control unit M2 is placed in a box in the form of a parallelepiped, having on one side an open area opposite the partition 61, the base 62 being mounted on the assembly area 2.1, and a cover 63 which extends to four other sides of the box.
    This box provides two
    The 5 electromagnets 4 and 5, arranged side by side, the Kor 65 and 66 of which in the shape of E, interacting with the fixed frames 67 and 68, also in the shape of E, are movable parallel to the base 62 and perpendicular to the partition 61. Two fixed roma 67 and 68 were installed with the possibility of replacement on a single cover 63. Thus, in the process of removing the cover 63
    5, two windings are available and can be easily replaced, for example, in view of a voltage change.
    As can be seen from FIG. 4 and 5. Each of korea 65 and 66 carries two side pins 69, 69
    0 -70, 70, included in two coaxial holes 169, 169-170. 170 fork articulated bearing 71. 72, installed pivotally on the base with the help of a hinge system, the axis of which is parallel to the axles 69, 69 -70. 70
    The forks 71 and 72 are formed by assembling two L-shaped structures parallel to each other, the vertical rods 73 and 74 of which carry two holes at the ends
    0 169..169-170, 170 and the corner areas of which are provided with two axles 75, 75-76, 7b. which are inserted into the drills made in the hinge fastening elements 77, 77 -78, 78, which are rigidly connected to the base 62,
    The free end of the horizontal bar 79, 80, which is oriented to the partition 61, forms a bend 82. 83 on which one of the ends of the traction spring is attached
    0 84, 85. the other end of which is held by a prominence rigidly connected to base 62.
    The springs 84 and 85 are pre-tensioned in order to act on the corresponding forks 71 and 72 with a force that tends to overturn them in a clockwise direction to the stop position at the end of the course, in which the horizontal bars 79 and 80 are parallel to the base 62, and to measles 65 and 66 electromagnets 4 and 5 occupy
    resting position and moved away from the fixed frame 67 and 68.
    In addition, the horizontal bars 79 and 80 serve as transmission levers for actuating the housings 86 and 87 slidably mounted parallel to the partition 61.
    Cases 86 and 87 have two parallel wings 88 and 89 - 90 and 91, connected by two cross sections 92 and 93, with both wings 88 and 90 resting on three pushers 57 sets of corresponding breakers 9-11 and 12-14. Both wings 89 and 91 are provided with each guide slide 94, 95, which enters a slot formed in a metal partition 96, rigidly connected to the base 62, and which extends parallel to the partition 61.
    The housings 86 and 87 are actuated by forks 71 and 72 in one direction through the introduction of stops 100 and 101 provided at the free ends of the horizontal bars 79 and 80 forks into the corresponding elongated cavities formed by the wings 88 and 90 by housing 86 and 87.
    In the excitation state of the electromagnet 4 (5), the corresponding plug 71 (72), which is subjected to the thrust by the spring 84 (85), holds the rm 65 (66) of this electromagnet in the rest position, while it acts on the pushers 57 through the stop (101) and housing 86 (87) with pressure to hold the respective interrupters 9-11 and 12-14 in the open position against the action of the springs 58.
    When this magnet is excited, it causes the fork 71 (72) to tip over in a counterclockwise direction against the action of the pull spring 84 (85). In parallel, a movable part consisting of a movable contact bridge 54, a pusher 57 and a housing 86 (87). which is no longer held by the limiter 100 (101) rises until then. as long as the moving contacts 55 and 56 are not pressed against the fixed contacts 48 and 49. Then the corresponding interrupters 9-11 or 12-14 are in the closed position.
    The excitation may be caused by a remote control circuit connected to the power terminals of the windings of two electromagnets provided on the cover (two terminals Bi, Bi. B2, B2 on the winding 15 (16) of the electromagnet).
    consists of a confirmation interrupter And, 12 normally closed type, having a fixed contact Cc C2), mounted on an insulating frame of the winding 15 (16), and a movable contact consisting of one end of a flexible plate DI, D2, the other end of which is rigidly connected with a cover 63. The contact pressure between the end of the plate DI, D2 and the fixed contact Ci, C2 is provided by means of a compression spring RI, R2 held by a rigid tong 105 (106) rigidly connected to the cover 63. The advantage of this device is to automatically turn off the power 15 hanks (16) of the electromagnet 4 (5) during removal of the cap 63.
    Two confirmation switches li and 12 connected to the two windings are located laterally with respect to electromagnets 4 and 5, and the complex consisting of the fixed contacts Ci and C2 and the ends of the flexible plates Di and D2 is located near the top edge of the cover 63, adjacent
    to the open surface of the box.
    FIG. 2, a confirmation breaker 2 is installed in the supply circuit of the winding 16 of the electromagnet shown in FIG. 3, whereas the chopper li li of FIG. 3 is set to
    winding supply circuits. 15 of the electromagnet shown in FIG. 2.. /. The actuation of the switches 11 and 12 from the core of the electromagnet is provided by two mechanical connections,
    which for each electromagnet 4 (5) includes a transmission part Ti (T2), fixedly mounted on the pins 69 and 70 provided on the bark of this electromagnet, and this part Ti (T2) has a lever
    107 (108). projecting radially in relation to the pin which moves with
    bark in a plane perpendicular to the axis
    pins 69 and 70 and shaft 109 (110) pivoting about an axis parallel to the pivot axis
    69 and 70 .. moreover, this shaft bears the radial lever 111 (112), the free end of which is provided with a rod 113 (114) in engagement with the lever 107 (108), as well as two fingers 115, 139-116, 138 ..
    It is necessary that two details of the transfer
    TI and T2 were mounted on two pins 69 and 70 opposite each other, which are located between two crust 65 and 66 of electromagnets 4 and 5 ..
    a shaft adjacent to the shaft 109. a radial lever 112 disposed to engage with the lever 107 mounted on a pin 69 rigidly connected to the bore 65.
    The shaft 109, which is located opposite the core 65, extends beyond its end in a form in the form of a groove 118, which covers the shaft 110 and carries at its end a radial lever 111 connected to the lever 108 fixed on the trunnion 70. rigidly connected to the bark 66.
    The fingers 115 and 116 are arranged to interact with the ends of the flexible plates DI and D2, which form the moving contacts of the confirmation switches H and 12 as follows.
    When one of the two electromagnets is turned off, and the polarity of the choppers 9-11, which it drives, is open (the position shown in Fig. 2), the lever 107 of the Ti part connected to this electromagnet is in a position allowing the shaft 110 to turn. counterclockwise. Therefore, the end of the flexible plate D2, which forms the movable contact of the confirmation interrupter 12 connected to another electromagnet 5, acts on the fixed contact under the influence of the spring.C2 causes the shaft 110 to rotate 110 by its action on the pin 115. The lever 112 returns the lever 112. Thanks to that the confirmation interrupter 2 is closed, the electromagnet 5 can be energized and can assume the position shown in fig. 3
    In this position, the fork 72 occupies an inclined position against the action of the stretching spring 85 and allows the polar interrupters 12-14 to close under the influence of the spring 58, the lever 108 acts on p, the lever 111 to hold the shaft 109 in an angular position, which finger 116 holds-end of the flexible plate DI confirmation switch 12 connected to electromagnet 4 removed from the fixed contact Ci.
    The winding circuit 15 of the electromagnet 4 is open and prohibits any possibility of initiating this: an electromagnet 4.
    The inverter shown in FIGS. 2 and 2. 3,: turning off the excitation of the electromagnet 5 will turn the plug 72 under the influence of the stretching spring 85 and go to the open state of the polar breakers 12-14, controlled by this an electromagnet 5. Moving in parallel, the lever; 108 releases the lever 111 and the finger 116 rotates with the shaft 109. allowing the flexible plate DI to return to the fixed-type contact
    Ci under the influence of the spring RI. As a result, the electromagnet 4 can be energized, in which case the inverter is in a state that is symmetrical to the state shown in FIG. 2 and 3.

This shutdown device was shown schematically by block 130, into which axis 131 penetrates the reset control button 132 and which has two actuators, namely, the first actuator 133, a pusher, designed to interact with
    0 by the upper surface of the wings 88 and 90 of the bodies 86 and 87, and the second actuator 134, the pusher, positioned so that it can interact with the fingers 138 and 139 attached to the fuses 109 and 110.
    The first actuating authority 133 may occupy two positions, namely
    the down position, which corresponds to the operating position of the shutdown module and the Stop and Auto button position; a position in which the body 133 does not exert any effect on the housings 86 and 87 so as to enable the polar interrupters 9-14 to pass their normally closed position under the influence of electromagnets 4 and 5;
    due to the deactivation of the released position in which it rests on
    0 housings 86 and 87 so as to keep all polar interrupters 9-14 open.
    The second actuator 134 (movable in the direction of the double arrow) can also assume a resting position (corresponding to the position of the Auto button) in which it is not exposed to the fingers 138 and 139, and an operating position (other positions of the button 132). in which he acts on two fingers
    0 138 and 139 for holding the shafts 109 and 110 in such an angular position, in which the fingers 115 and 116 provide the opening of the confirmation contacts h and 12 of the two electromagnets 4 and 5. to exclude them
    5, when button 132 is not in the Auto position.
    position to release position.
    The protection devices associated with the switching device 130, which are located in the indirect switching control module M3, have been shown schematically by block 143 in FIG. 3. They have an actuator body 144 — a push rod arranged so as to act on the shut-down organ 142 due to the detection of the current anomaly passing through the polar breakers.
    The electrical connections between the current lines passing through these polar breakers 9-14 and these protection devices are established by the six pairs of coupling elements 145 provided on the step element of the partition 61.
