    - 1 POWER BUS FOR ELECTRICAL LINE PROTECTION DEVICES The present invention relates to a power bus for electrical line protection devices positioned alongside one another in rows in a box or electricity distribution 5 cabinet for a household or industrial facility. It therefore relates to a power supply device on which it is possible to connect all of the electrical devices protecting an electrical facility connected downstream, for example such as circuit breakers, switches or other differential, functional secondary, etc. products. The concerned type of bus includes a distribution column, a kind of 10 framework or spine of the system, conveying active conductors, namely primarily at least one phase of the grid, as well as, if applicable, data transmission conductors, or even in some cases the neutral conductor. The distribution column is organized such that there is a lateral distribution coming from said conductors, on at least one side of the column, using transverse distribution strips whereof at least one end protrudes 15 past the column in a transverse direction perpendicular to the axis of the column, at a regular frequency in the direction of said axis, making it possible to order devices in rows along the column. There are four main types of issues that traditionally arise in the context of electrical distribution done by this type of power bus: 20 - guaranteeing maximum security, while providing protection for users by insulating the device in accordance with standard IP2X; - ensuring stability of the products, i.e., of the electrical devices connected to the power bus, and preventing poor fastening, i.e., mechanically insufficient fastening, from creating electrical operation problems for the assembly or 25 creating risks for users; - allowing fast assembly, for example using direct plug connectors based on mechanical cooperations of the rigid conductor terminal / spring plate type; and - ensuring management of the neutral conductor, or even ground 30 conductor, in particular making it possible to meet the preceding conditions, for example without there being any disconnected neutral wires, in the pending state, of 27/08/13,dh-21019 - speci - cdm.docx,1 -2 course available for connection but not providing a quick connector mechanism on the one hand, and not having a sufficient safety guarantee on the other hand. The current power supply devices that meet the distribution column geometry previously described manage the aforementioned issues in a more or less 5 satisfactory manner. Thus, in many cases, the electrical devices do not hold correctly in the panel, which may if applicable cause insulation problems. In certain cases, the products are kept attached to the distribution column based solely on screwed connections, which poses the problem of stability on the one hand, the mechanical link being able to prove defective, and slowness or even difficulty of assembly on the 10 other hand. It has also been noted that certain configurations include conductors in a free wired form, which are potentially dangerous and require a connection using non optimized traditional methods, including screwing. It should be noted that, for many devices, the neutral is free, which at the very least makes it difficult to connect. 15 The configuration of the invention responds to these issues, by implementing an original solution that additionally makes it possible to work locally and under good conditions on each electrical device individually, without completely disassembling it. The solution according to the invention furthermore provides indicators and means guaranteeing the correct connection of the product or, 20 conversely, the fact that said product is not powered on, although it is not disassembled. To that end, as well as in order to perform other functions that will appear in the present description, the power bus according to the invention is primarily characterized in that the devices are individually fixed on at least one moving 25 carriage cooperating with a distribution strip and sliding on a distribution pedestal extending on either side of the transverse strips, the sliding being ensured by means for guiding the translation in the transverse direction between two stable positions corresponding to a disconnected position and a connected position of the device reflecting two relative positions of a carriage and a transverse strip, and respectively 30 making it possible to assemble/disassemble a device on at least one carriage and connect it to a number of transverse strips corresponding to the number of carriages, said carriage including means for insulating the strip and blocking the translation of 27/08/13,dh-21019 - speci - cdm.docx,2 -3 the carriage that are activated in the disconnected position and when no electrical device is present on the carriage. The idea at the base of the invention therefore lies in the fact that the devices are no longer directly connected to the central column, but are mechanically 5 secured to one or more sliding carriages performing mechanical functions for fastening an electrical protection device as traditionally used in electricity distribution cabinets, and participating in its electrical connection. The idea of the carriage furthermore makes it possible to sequentially perform the mechanical securing of each device, without taking the electrical connections into account, then 10 secondly to place electrical connections, after sliding of the carriage(s) and once the mechanical fastening of the device on the carriage is complete. This sequential approach makes it possible to perform and simplify each function, i.e., the first mechanical fastening function and the second electrical connection function, by separating them. It furthermore makes it possible to 15 substantially improve safety, insofar as the first mechanical fastening is done powered off. The carriages are designed such that, when they are in their position allowing the mechanical placement of each device, no contact is possible with a part that is powered on. During the sliding for electrical connection, the device is already mounted on its carriage through which the electrical connection is done, again with 20 no possibility of direct contact from the outside. This remains true during the reverse operation, in order to electrically disconnect an electrical device: at no time is there any possibility of electrical contact with a part that is powered on. However, when one goes from the connected position to the disconnected position, which alone allows it, the disassembly of a device is 25 then done powered off. The assembly of the inventive device, including the carriages, has been designed such that the mechanical connections are robust, and they make it possible to work quickly owing to connections / guides designed to be immediate and quick to use. 30 In practice, according to one possibility, a raised portion of the pedestal forms the distribution column of the bus, which further includes: - one or more axial bars conveying the phase(s), 27/08/13,dh-21019 - speci - cdm.docx,3 -4 - the transverse distribution strips distributing them laterally, and - a lid equipped on at least one side with ribbed protuberances for guiding the carriages and from which the transverse strips protrude. In fact, more specifically, the carriages are alongside each other and have a 5 width, in the direction of the axis of the central column, equal to the distance between the median axes of two adjacent strips. Such a configuration makes it possible to best manage the available space insofar as the devices are then also alongside each other, by large side faces of their box. In the event standard modular devices are used, the carriages have said standard 10 width, called modular width. According to one possible configuration, the carriage includes, in an end promontory interposed between the device and the distribution column, at the height of the transverse strips, an opening allowing the passage of one end of the strip, which is kept in the volume of the promontory in the disconnected position and 15 protrudes from the opening in the connected position, and means for sealing said opening which, when activated, prevent contact with said end in the disconnected position as well as free sliding of the carriage toward the connected position. In other words, when the carriages are in the disconnected position, the strips are not accessible to a contact, and are invisible. They may only be visible in 20 the connected position, but in that case, the existence of a device on the carriage causes the strip to connect to the inside of the box of said device, and is therefore no longer accessible. It should be noted that the sealing means, ensuring the IP2X insulation in the disconnected position, prevent the carriage from sliding toward its connected 25 position without using a specific, and therefore desired, manual maneuver. This further reinforces the safety resulting from the existence of this carriage. More specifically, according to one possibility specific to the invention, the means for sealing the passage consist of a latch of the guillotine type movable in a direction perpendicular to the movement direction of the carriage, an actuating end of 30 which protrudes from the carriage when the latch is in a stable idle position, said latch being movable against return means and including a slit aligned with the transverse strip and the opening so as to allow the passage of said strip when the 27/08/13,dh-21019 - speci - cdm.docx,4 -5 actuating end is actuated, said slit being offset from the opening and sealing the passage in the idle position. In the absence of bias, in the disconnected position of the carriage, the latch seals the passage. 5 To improve the positioning of the electrical devices on the carriages, squares may be placed at the foot of the end promontory, between the latter and a base plate of the carriage, at the side edges of said base plate. They prevent sideways movement of the devices on their carriage on the one hand, and poor connection of the devices, straddling two carriages, i.e., two adjacent transverse strips at the same 10 time, on the other hand. Lastly, according to one possible configuration, the accessible actuating end of the latch comprises an orifice for the passage of a lock, making it possible to confine the electrical devices. The problem of managing the neutral was mentioned above. According to 15 one possibility, the power bus according to the invention may include, on each existing distribution side by the transverse strips, a neutral bar fastened to the pedestal and including connection blades oriented in the translation direction of the carriage, one blade under each carriage, and with a length provided to make them accessible in the connected position of the carriages. 20 In substance, the bus according to the invention makes the neutral available, irrespective of whether it is used, for any electrical device fixed on a carriage. These plates are preferably provided, both in terms of their orientation and length, to cooperate with the carriages while respecting the same goals as the transverse distribution strips, i.e., in accessibility when the carriage is in the 25 disconnected position, and electrical accessibility otherwise. In fact, according to one possible configuration, each neutral bar is positioned in a slot formed in the pedestal following an orientation parallel to the distribution column, at least one portion of the blades extending above and parallel to the pedestal. 30 Each neutral bar in reality includes an axial rod or bar that develops along the distribution column, in said slot formed in the pedestal, and bent blades at regular intervals such that the free ends of the blades are parallel to the pedestal and 27/08/13,dh-21019 - speci - cdm.docx,5 -6 positioned in a predetermined manner relative to the pedestal on which the carriages, which are configured to account for said blades, slide. Each carriage in practice includes a base plate provided with at least one longitudinal recess capable of adjusting on at least one raised portion protruding 5 from the pedestal, which constitutes a rail for guiding the translation of said base plate. This is a sort of rail on which the base plate adjusts itself, said base plate then being able to slide while being guided, a single degree of freedom being granted to it. A blade end portion of the neutral bar extending above the pedestal is housed on the one hand between the bottom of the recess of the base plate and on the 10 other hand a support protruding from the pedestal, said blade end portion remaining below the base plate in the disconnected position and leaving the base plate in the connected position. To summarize, each carriage, when in the disconnected position, does not allow any element of the electrical circuit to appear. 15 According to one possibility, said end portion of each blade includes an insulating coating with a length greater than said portion, capable of sliding along the blade over a distance at least equal to said end portion in order to strip the free end of the blade protruding from the carriage in its connected position, a flange equipping the distal end of the insulating coating of said free end being driven, so that the 20 coating covers the end portion when the blade has been stripped, by a low wall protruding from the bottom of the recess of the base plate and exerting an action on the flange when the carriage is moved toward its disconnected position. If the carriage with no device is moved into its connection position, the end portion of the blade appears, covered by its insulating coating. Certain pieces of 25 equipment are equipped with a prismatic protuberance, or "insulating screw joint", for connecting to the neutral that protrudes from their base plate in the carriage, which pushes the insulating coating back when the carriage is moved toward its connection position, producing the simultaneous connection to the neutral for this type of device. It is, however, necessary to "reset" the position of the insulating 30 coating during the reverse movement, which is done by the aforementioned low wall. Additionally, according to the invention, the support for the blade may include a raised portion forming a hard spot followed by an end abutment, between 27/08/13,dh-21019 - speci - cdm.docx,6 -7 which the flange is positioned when the carriage is at the end of the travel to its disconnected position. The hard spot serves as a haptic acknowledgment member indicating that the "reset" has indeed been done, i.e., that the insulating coating is again covering the end portion of the blade. 5 According to one particular arrangement of the invention, the central part of each carriage base plate, on its face across from the recess, has a profile assuming the form of a standardized rail for fastening electrical devices with two walls perpendicular to the base plate topped by two rims flaring outwardly in a direction substantially parallel to said base plate. 10 In principle, such profiles are standardized, which means that the distances between the walls on the one hand and the free ends of the rims on the other hand are fixed. In the case at hand, the distance between said walls of the profile is increased relative to the standardized profiles so as to avoid any angular movement 15 of the devices when they are fixed there and such that, on the promontory side, the distance between the free ends of the rims remaining the standardized distance, the protrusion of the rim relative to the wall is reduced. Its end is also rounded, so that the fastening on the profile of a latch sliding on the base plate of the modular electrical devices against return means makes it possible to disassemble the modular 20 device by pivoting the latter around the opposite end of the profile. In fact, the purpose of this adaptation of the profile is twofold: - maximize the distance between walls to come as close as possible to the separation between the end of sliding latch and the tip facing it in the central part of the base plate of a modular device provided to be fixed on a rail, to eliminate 25 any angular movement as mentioned above; - facilitate the separation of the modular product by rounding the end of the profile opposite that which serves as a pivot axis when said product is disassembled. The advantage of this configuration is that it will then be possible, with a 30 power bus according to the invention, to reuse modular devices used in other configurations until now, i.e., simply fixed on a rail of the DIN type equipping other types of power supply boxes. 27/08/13,dh-21019 - speci - cdm.docx,7 -8 In- this perspective, and to allow connection as traditionally used in particular in the bridge bar systems used in the type of box mentioned above, the ends of each transverse distribution strip may be provided in the shape of a fork. The square-shaped ribs guaranteeing the proper positioning of the modular 5 device on the carriage, the existence of which was mentioned above, are in fact positioned between the profile assuming the form of a standardized rail and the end promontory of each carriage. They prevent an electrical device from straddling two adjacent carriages and connecting to two adjacent branches of two separate forks. It should be noted that the distance between the ends of the transverse 10 distribution strips and the input connectors of the electrical devices placed on the carriages is greater than 4 mm in the disconnected position of the carriages, such that the power bus according to the invention can operate as a disconnecting switch, since it obeys the standardized distance constraints between conductors. The invention will now be described more detail, in reference to the 15 appended figures, in which: - figure 1 shows a power bus according to the present invention, in a version where the distribution column is central, and includes two sets of side carriages; - figure 2 shows a top view of the power bus of figure 1; 20 - figure 3 shows a slight perspective side view; and - figure 4 shows the design of the carriage according to the present invention, in perspective view, while showing the recesses in particular used for translational guiding. In reference to figure 1, the distribution bus according to the invention 25 includes a pedestal (1) having a raised central part (2) and two side portions (3) and (4) on which sliding carriages (5) are positioned. The raised central part (2) of the pedestal (1) supports conductive strips (7), in this case conveying all three phases, topped by a blade (8) and to which transverse distribution strips (9) with a forked end are secured. The assembly formed by the raised central part (2) of the pedestal (1), 30 the bars conveying the phases (7), the lid (8) and the transverse strips (9) constitutes the distribution column, in this case positioned centrally in a symmetrical bus configuration. 27/08/13,dh-21019 - speci - cdm.docx,8 -9 The carriages (5), one example of which is shown in figure 4, are shown in figures 1 and 2 in the disconnected position in the left part of the figure and the connected position in the right part of the figure, respectively. To make it possible to assess the relative positioning, in particular of the carriages (5) and the end of the 5 transverse strips (9), the two carriages situated in the first plane have been removed. In a three-phase configuration as shown in the figures, the transverse strips (9) regularly and periodically distribute the three phases. The pedestal (1) furthermore includes symmetrical slots (10) oriented along the distribution axis, i.e., longitudinal axis of the bars (7) conveying the phases. The slots (10) each house a neutral bar to 10 which bent blades (11) are attached following a regular spatial frequency that corresponds to that of the transverse strips (9). In the disconnected position, shown in the left part of figures 1 and 2, and which is also that shown in figure 3, which is consequently a left side view, the forked ends of the transverse strips (9) as well as the bent blades of the neutral bar 15 are not visible, but remain inside the carriage (5). The sealing means (12), in this case latches of the guillotine type that can be actuated manually for example via an end (13) equipped with a locking orifice (23), make it possible on the one hand to provide IP2X protection while preventing any contact with the transverse strips (9) electrically connected to the bars (7), and on the other hand to acknowledge the 20 correct positioning of the carriage in the connected mode when said carriage (5) is completely slid toward the central distribution column. In this scenario, shown in the right part of figures 1 and 2, the forked ends of the transverse strips (9) are accessible, having crossed the opening (14) provided at their level in an end promontory (15) of the carriage (5) overhanging the base 25 plates (16) of the latter provided to be interposed between the distribution column and the electrical protection devices to be fixed on the carriages (5). Said base plate (16) includes, in its central part, a profile (17) similar to the DIN rails on which electrical protection devices are fixed in certain distribution cabinets. A rounded portion (24) one of the ends of the profile (17) (see figure 1) maintains significant 30 travel for the latch equipping the devices to be installed on the carriages (5), but the length between the walls of said profile (17) is provided such that said devices may be disassembled by rotation around the opposite end (25) of the profile (17), as was 27/08/13,dh-21019 - speci - cdm.docx,9 - 10 explained previously. This feature is necessary for the possibility of disassembly to exist, since the user does not have access to said latch when the device is fixed on the carriage (5). To go from the disconnected position shown in the left part of the figures to 5 the connected position in the right part, each carriage (5) slides on a rail (18) over a length allowing it to abut against the central distribution column, the base plate (16) being guided by said rail (18), while the upper part of the promontory (15) is guided by shape matching in contact with prismatic ribbed protuberances (19) laterally protruding from the lid (8) of the central distribution column, from which the forked 10 ends of the side strips (9) emerge. In reference to figure 3, the openings (14) are sealed by the sealing means (12), which in this case are made up of a latch whereof the upper part is provided with an actuating end (13) allowing it to be manually actuated against a helical spring (not shown), and which has a slit (20) calibrated to allow the passage of the 15 forked ends of the transverse strips (9) when it is aligned with the opening (14). In the configuration shown in figure 3, the slit (20) is placed so as to seal the opening (14), which one can see is not situated at the same level as it. It is consequently appropriate for the user to exert pressure on the upper part of the sealing member (12) against the spring, so as to cause it to descend in order to make the slit (20) and 20 the passage (14) coincide. In that case, the carriages (5) can slide on the rails (18) and, guided by the ribbed protuberances (19), may be moved toward the central distribution column. Figure 4 also shows the cooperation between the latch of the sealing member (12) and the carriage (5), the sealing member (12) again being situated in its 25 idle position sealing the passage created by the opening (14) (not shown). The carriage (5) essentially includes two hollow volumes oriented substantially perpendicular to each other, the first volume being formed in the end promontory (15), allowing guiding in contact with the protuberances (19) that adjust in the upper part of the hollow volume delimited by the side and upper walls of said end 30 promontory (15). A second volume or hollow recess (21) is situated below the base plate (16), and adjusts by shape adaptation to the rails (18) provided in the pedestal (1), on which rails (18) the carriage (5) can then slide. The recess (21) is closed, at its 27/08/13,dh-21019 - speci - cdm.docx,10 - 11 end, by a partition in which an orifice (22) is formed for the passage of the bent blade (11) coming from the neutral bar (10). The end portion of these blades (11) is coated with an insulator (26) ending with a flange (27), as in the connected position for example shown on the right in 5 figures 1 and 2, and said portion protrudes from the carriages (5) only by its insulated portion. It does not appear in the disconnected position of the carriage (5), shown on the left part of the same figures 1 and 2. Said insulating coating (26) can slide, for example driven by an "insulating screw joint" protruding from certain devices and producing the connection to the 10 neutral, causing it to slide as the carriage (5) is moved toward its connected position. In the reverse movement, a low wall (28) protruding from the bottom of the recess (21) pushes the insulating coating (26) back toward its end position as shown, and reached when the flange (27) crosses a hard spot (29) and reaches an abutment (30) of the support (31) (see figure 1, enlarged detail). The position of the insulator (26) is 15 then reset. 27/08/13,dh-21019 - speci - cdm.docx, 11
