Definitions

  • the invention relates to a trip device of an electrical circuit breaker with molded housing having, by pole, a pair of contacts elastically biased in contact in the closed position of the circuit breaker and capable of separating under the action of electrodynamic repulsion forces when the current flowing the contacts exceed a predetermined threshold to generate a limitation of said current, said trip device having an overload and / or short-circuit fault detector which actuates a mechanism for controlling automatic opening of the circuit breaker on fault.
  • a known trigger (US-A-3,631,369) of the kind mentioned, comprises a movable pallet, arranged in bimetallic strip and subjected to the action of the electromagnetic trigger. An extension of the pallet projects into the gas exhaust duct of the breaking chamber. During a cut, the gas flow drives the pallet to the trigger position. In the majority of circuit breakers, the gas exhaust pipe is distant from the trip device and the aforementioned device is therefore not applicable. The pallet is subjected to the pooling action of gases and its proper functioning is quickly hampered. Each pole must be equipped with such a trigger and a trigger selectivity is not conceivable because the actuator reacting to the flow of gases is integrated into the thermal and magnetic trigger.
  • the object of the present invention is to produce a trigger ensuring both the limitation and the selectivity of triggering by simple, universal and reliable means.
  • the trip device is characterized in that said actuator device constitutes a sealed assembly only in communication with the contact zone, and which has a limited actuation stroke.
  • the pressure in the contact area in particular in the breaking chamber, is a direct function of the power of the arc, and it can quickly reach significant values, for example from 3 to 10 bars.
  • This overpressure acts on a simple membrane or movable piston device which actuates the circuit breaker tripping mechanism.
  • the rise in pressure and the transmission of this pressure to the detector are all the faster the higher the currents.
  • the device is not sensitive to low currents, and an untimely tripping on a simple overload can easily be avoided by providing a return spring for the piston, or the measurement membrane.
  • the actuator is a sealed or quasi-sealed assembly formed by the cylinder with the piston or the membrane and the connection conduit between the cylinder and the breaking chamber.
  • This small section conduit can be relatively long and its housing in the housing is easy.
  • the displacement of the piston requires only a tiny flow of gas in the conduit and this flow occurs almost entirely before the pollution of the gases by the action of the arc. The actuator is thus protected from these polluted gases.
  • the present invention starts from the observation that a cut in a limiting circuit breaker always generates a large arcing voltage, and therefore a significant arcing energy resulting in an increase in the pressure in the breaking zone.
  • This pressure increase is ultra-rapid, and the selectivity can be ensured by the use of a calibrated return spring so as to trigger at a predetermined pressure.
  • each pole of a multipole circuit breaker comprises an overpressure actuator, so as to intervene as soon as an overpressure occurs in any of the poles, and carry out tripping as quickly as possible.
  • the piston of the overpressure actuator can be common to the different poles, these being connected to the piston by conduits equipped with a non-return device.
  • the different interrupting chambers are preferably connected to a common manifold with the interposition of a non-return valve, this manifold itself being connected by a conduit to the piston or to the membrane of the overpressure actuator, which acts on the circuit breaker trip bar.
  • the trip on fault can be obtained by a standard thermal or electromagnetic trip, or by a static trip with polarized relay. All these trips and actuators act on the same trip bar which releases the mechanism of opening of the circuit breaker, in a way well known to specialists.
  • the overpressure actuator can therefore include a piston of small surface area, of the order of one square centimeter, and this small size facilitates housing in a molded case, possibly of an existing device.
  • a pole of a molded case circuit breaker 10 comprises a pair of contacts 11,12 arranged in a breaking chamber 13 equipped with deionization plates 14.
  • the breaking chamber 13 is delimited by partitions 15 of which one is traversed by an arm 16 for supporting the movable contact 12.
  • the breaking chamber 13 is almost leaktight and communicates via a channel 17 of restricted section with the outside of the molded housing 10.
  • the movable contact arm 16 is pivotally mounted on a bar 18 belonging to a control mechanism 19, having a lever 20 for manually opening and closing the contacts 11,12 and a latch 21 for triggering the mechanism 19.
  • the movable contact 12 is biased by a spring 22 in the closed position, being able to pivot counterclockwise under the force of electrodynamic repulsion generated by the current flowing through the contact arm 16 and the contacts 11,12.
  • the hooking 21 is controlled by a trip bar 23 common to the different poles of the circuit breaker.
  • the circuit breaker comprises a standard trip switch with bimetallic strip 24 and with an electromagnetic coil 25, both acting on the trip bar 23.
  • Such a circuit breaker is well known to specialists and it is unnecessary to describe it in more detail. It suffices to recall that during a short circuit the repulsion of the contacts 11, 12 causes a rapid opening of these contacts, against the force of the spring 22, this rapid opening causing a limitation of the short-circuit current. .
  • the opening of the contacts 11, 12 is confirmed by the intervention of the electromagnetic trip device 25 acting via the trip bar 23 on the latch 21, which opens the mechanism 19 of the circuit breaker.
  • the circuit breaker comprises an overpressure actuator comprising a piston 26, cylinder 27 assembly cooperating with the trigger bar 23.
  • the piston 26 mounted to slide in the cylinder 27 carries a rod 28 capable of striking the trigger bar 23.
  • a return spring 29 maintains the piston 26 in the retracted position, shown in FIG. 2.
  • the face opposite to the rod 28 of the piston 26 is subjected to the pressure prevailing in the chamber 30 which communicates via a conduit 31 with the interrupting chamber 13.
  • the conduit 31 opens into the chamber 13 in the vicinity of the deionization plates 14, but the pressure test can be carried out in any location of the chamber 13, the uniformity of the pressure inside this chamber being almost instantaneous.
  • the circuit breaker can be multipolar and in this case, each pole can be equipped with its own overpressure actuator 26,27 acting on the trip bar 23. During a short circuit, the most charged pole causes tripping by the 'increase in pressure in its breaking chamber 13, this triggering causing the opening of all the poles of the circuit breaker.
  • three poles P1, P2, P3 of a three-pole circuit breaker communicate by conduits 31 with a collector 32, itself connected to the chamber 30 of the overpressure actuator 26 , 27.
  • the opening of the conduits 31 in the collector 32 is capable of being closed by a non-return valve 33, preventing the passage of gases from one pole to the other.
  • the pressure build-up in the breaking chamber of the first pole P1 is the fastest, and this pressure is transmitted by the conduit 31 and the manifold 32 to the overpressure actuator 26,27 , the valve 33 being open.
  • the other two poles P2, P3 are isolated from the collector 32 by closing their corresponding valve 33, and the device actuator retains its quasi-tightness.
  • the invention is applicable to circuit breakers with static tripping using current transformers for detecting overload or short circuit. These current transformers supply a signal to an electronic processing unit which delivers a tripping order to a polarized relay 34 when the predetermined thresholds are exceeded.
  • the polarized relay 34 includes a plunger core 35 held in the retracted position by a permanent magnet 36, and biased in the control position of the trigger bar 23, by means of a pusher 38, by a spring 37.
  • the tripping order is transmitted to a coil 39 which releases the core 35.
  • the overpressure actuator 26,27 is adjacent to the polarized relay 34 and the rod 28 is arranged opposite the trigger bar 23 to activate the latter during an overpressure.
  • the trigger bar 23 carries a lug 40 capable of cooperating with the rear face of the head of the pusher 38, leaving a clearance "j" sufficient for the displacement of the trigger bar 23 under the action of the overpressure actuator 26,27, without displacement of the core 35 of the relay 34.
  • This tab 40 causes, after triggering of the mechanism 19, the disarming of the polarized relay 34.
  • the curves in FIG. 5 show the mode of action of the trigger according to the invention.
  • the curve “a” shows the separation distance of the contacts 11,12, during an opening on short circuit by electrodynamic repulsion of the movable contact 12.
  • the curve “b” shows the variation of the arcing voltage corresponding to the opening of the contacts 11,12 .
  • Curve “c” illustrates the growth of the presumed short-circuit current, while curve “d” corresponds to the current limited by the electrodynamic repulsion of the contacts 11,12.
  • the curve “e” shows the variation of the pressure in the breaking chamber 13.
  • the separation of the contacts 11,12 occurs at an instant "t1" and the overpressure actuator causes the opening of the mechanism 19, and therefore , that of the three poles of the circuit breaker at an instant "t2" confirming the opening of the contacts by electrodynamic repulsion.
  • a piston 26, with a diameter of 10mm has made it possible to obtain forces largely sufficient to actuate the trigger bar 23.
  • a piston of this size can easily be accommodated in the molded housing 10, and the conduit 31 of small section allows capturing the pressure at any location in the interrupting chamber 13.
  • the usual sealing of the interrupting chambers 13 is largely sufficient to obtain the necessary overpressures, and it is unnecessary to provide additional means for sealing these chambers.
  • the assembly is particularly simple and the selectivity is obtained by the use of return springs 29 of appropriate size.
