Definitions

  • the present invention relates generally to circuit breakers multipolar differentials.
  • these multipole differential circuit breakers include, on the one hand, a certain number of breaking compartments, at the rate of one per pole, and, on the other hand, for all of these breaking compartments, a differential protection compartment.
  • Each terminal has a terminal associated with it. input and an output terminal, with, acting between them, contacts switches, at least one of which is movable under the control of a mechanism commonly called "lock".
  • this mechanism is itself under the control of at least one organ of trigger, such as for example a magnetic trigger and / or a thermal trigger, capable of causing if necessary a command to open the switch contacts.
  • organ of trigger such as for example a magnetic trigger and / or a thermal trigger
  • the pole is a neutral
  • a neutral which is for example the case when, being a four-pole differential circuit breaker, such a neutral is associated with three phases
  • no triggering device is usually provided, the corresponding mechanism then being simply under the control of the mechanism of any of the phases.
  • the differential protection compartment is equipped, him, a fault detector able to deliver a differential current in response a fault, a sensitive relay served by this fault detector, and a mechanism, also commonly known as a "lock", capable of intervening in triggering on the mechanism of at least one of the compartments of break.
  • the present invention relates more particularly to the case where the circuit breaker Multipolar differential concerned constitutes what is commonly called a modular device.
  • the housing of such a modular device comprises, parallel to each other, two main faces, and its width, equal to the distance separating one from the other these main faces, is a multiple of a basic module given common to all modular devices of same type.
  • the breaking compartments are usually arranged parallel to each other, and they all have the same width equal to the basic module.
  • the differential protection compartment extends also most often to date in parallel with the breaking compartments, by being in practice attached to these at one or the other of the ends of the alignment they form, and its width is equal to three times the module basic.
  • the overall width of a differential circuit breaker four-pole for example is most often equal to seven times the modulus of based.
  • the width of each of the compartments of cut-off remains equal to the basic module, and the protective compartment differential is distributed longitudinally between these breaking compartments, everything happens as if the volume available inside the case was split in two following a plane perpendicular to both the main faces of this housing and its fixing face, part of this volume being fragmented transversely between the various breaking compartments while the other is occupied longitudinally by the differential protection compartment.
  • the axis of the triggering member magnetic of each of the breaking compartments extends, in practice, and almost necessarily, perpendicular to the fixing face of the housing, and, the influence of this magnetic trip member being greater along this axis only transversely to it, the available volume according to this same axis for the arc extinguishing chamber usually associated with switch contacts is reduced accordingly, to the detriment of the power of break.
  • differential protection compartment extends longitudinally over the entire width of the housing, transversely with respect to to the switch-off compartments, the electrical connections to be made between the many internal components of these various compartments are particularly complicated and difficult to achieve.

  • the decision is made, according to the invention, to reduce the width of the switch-off compartments at a fraction of the basic module.
  • the layout according to the invention further allows, advantageously, for some at least of the constituents to be used, to economically take advantage of achievements already known and proven in the same field.
  • the mechanism of the breaking compartments that is to say the "lock” thereof, can advantageously be of the type which, for a circuit breaker bipolar neutral phase of width equal to the basic module, was the subject of French patent filed August 4, 1994 under No 94 09691 and published under No 2,723,470.
  • the differential protection compartment mechanism i.e. the "lock” thereof, may advantageously be of the type which, for a differential neutral phase tripping device with overall width equal to twice the basic module, was the subject of the French patent filed on May 31 1994 under No 94 06585 and published under No 2 720 548.
  • the axis of the magnetic tripping device of the switching compartments can advantageously extend parallel to the fixing face of the housing, at benefit of the space available for the arc extinguishing chamber at the right of this magnetic trigger, and, therefore, for the benefit of the power of break.
  • the coupling winding to destination of the differential protection compartment is inserted between the input terminal and magnetic trip device.
  • the volume available downstream of the triggering member magnetic can advantageously be used to full for the only room arc extinction, again for the benefit of the breaking capacity.
  • the winding of coupling to the differential protection compartment is connected to the magnetic trip member by a return section, which is parallel to the axis of this magnetic trip member, and which, for all the cut-off compartments extend to the same level.
