Definitions

the present invention relates to an electrical switching device intended to be fixed on a mounting support and comprising at least one breaking module and at least one module housing a complementary electrical function, at least one of the modules housing a complementary electrical function being located next to at least one of the abovementioned cut-off modules, the or each cut-off module comprising a breaking chamber.
the present invention solves these problems and proposes an electrical switching device comprising a certain number of breaking modules as well as at least one module providing a complementary electrical function, in which either the nominal intensity or the performance of the complementary function are increased. , while maintaining the cutoff performance of the device and without increasing the overall width of the device.
the subject of the present invention is an electrical switching device of the kind mentioned above, this apparatus being characterized in that the module's interrupting chamber situated opposite the complementary module has a domed face towards the inside of said chamber. cutoff so as to create inside said chamber a space for housing a portion of the volume of the module housing the complementary function and in that the ends of said interrupting chamber encroach on the volume of the complementary module.
the or each of the breaking chambers comprising a stack of plates extending substantially parallel to each other, the edges of the plates of the aforementioned chamber, located opposite the complementary module, are located in a plane curved towards the interior of the corresponding break chamber.
the (the) module (s) cutoff (s) respectively the (the) pole (s) of a circuit breaker, and the module housing the complementary function is a differential protection module.
the differential protection module comprises a torus and the torus is housed in part in the volume of the (or) module (s) nearby cutoff (s).
this apparatus comprises a differential module surrounded on each side by a breaking module housing a circuit breaker pole, the two faces of the two breaking chambers of the two breaking modules located on either side of the differential module. being curved inwardly of said chamber.
the or each cut-off module comprising an electromagnetic coil
this apparatus is characterized in that the or each cut-off module comprises at least one wall comprising an offset so as to form two portions of modules of different widths.
width being the dimension of the apparatus measured parallel to the alignment direction of the modules, the module portion having the smallest width accommodating the interrupting chamber and the module portion having the largest width accommodating the coil, said coil having a diameter greater than the width of the corresponding interrupting chamber.
the differential protection module comprises a torus placed between two interrupters opposite, and the axis of the torus extends parallel to the axis of the coil (s).
FIG 1 is a partial sectional view of a bipolar differential circuit breaker according to the invention, in a plane parallel to the base of the device,
FIG. 2 is a perspective view, illustrating a set of plates constituting a breaking chamber according to the invention.
FIG 3 is a schematic representation, illustrating in a plan view, a differential multipole circuit breaker according to the invention, according to a particular embodiment of the invention.
FIG. 1 shows the inner part of a bipolar differential circuit breaker D comprising a differential module 1 surrounded by two breaking modules 2, 3.
the differential module 1 comprises a core 4 traversed by primary conductors 5 and the breaking modules 2, 3 each comprise a breaking chamber 7.8, each breaking chamber 7.8 comprising a set of plates 9,10 juxtaposed and extending substantially parallel to each other and to the base of the device.
the faces 11,12 of the cutoff chambers 7,8 located opposite the torus are curved towards the inside of said chambers.
the width of the plates has been reduced in the center of the breaking chambers 7.8 and increases as we approach the ends 13,14,15,16 of said chambers.
the edges 10a of the plates facing the complementary module are located in a domed plane towards the inside of the corresponding interrupting chamber. This made it possible to create inside the breaking chambers 7.8, a space E, F making it possible to house a portion of the torus 4, the dimensions of which have therefore been increased.
the decrease in the width of the plates at the central portion of the cutoff chambers 7.8 is offset by the increase in the width of the plates at the ends 13 to 16 of the chambers 7.8, which results in the performance electrical shutdowns are not changed.
the invention has thus made it possible to produce a cut-off chamber allowing the encroachment of the torus into the breaking poles without penalizing the cutoff by, on the one hand, creating an additional space for accommodating the torus, the dimensions of which have been increased and on the other hand, to increase the width of the chamber at the ends of said chamber.
the torus is surrounded by the material of the chamber, the amount of material being kept so as to maintain the breaking potential, all without increasing the width of the device.
a multipole differential circuit breaker comprises a differential protection module 1 surrounded on each side by two breaking modules 2, 3, 17, 18.
Each cutoff module 2,3,17,18 comprises a breaking chamber 7,8,19,20 housing plates 9,10 arranged parallel to each other and an electromagnetic coil 22,23,21,24.
Each portion 2a, 3a, 17a, 18a of the cutoff module 2,3,17,18 housing the coil 21 to 24 is offset relative to the corresponding breaking chamber 7,8,19,20 so that each breaking module 2,3,17,18, over a length substantially corresponding to that of the electromagnetic coil, encroaches on the adjacent cut-off module or on the complementary module.
the partition walls 26,27,25,28 of the cutoff modules 2,3,17,18 have, at the separation between the breaking chamber and the housing of the coil, an offset 26a, 25a , 28a, 27a towards the complementary module 1, so as to form two portions of different width modules L1, L2, the latter being measured parallel to the alignment direction D of the modules.
This arrangement is particularly advantageous in the case where the torus is placed so that its axis is parallel to the axis of the coils. Indeed, this particular arrangement of the toroid allows the offset of the partitions so as to enlarge the space in which are housed the coils.
the invention is advantageously applicable to differential circuit breakers and generally to monobloc modular electrical switching devices comprising a central or lateral complementary function such as an integrated remote control, an exhaust gas recirculation system, etc.
