Definitions

  • the invention relates to a breaking chamber of a low-voltage circuit breaker of high intensity.
  • EP 0 306 382 discloses a multipole circuit breaker molded insulating housing containing a control mechanism coupled to a switching bar so as to ensure the opening and closing of all the poles of the circuit breaker.
  • Each pole comprises a fixed contact member, a movable contact member and an arc extinction chamber.
  • the fixed contact member comprises a conductive fixed range of current supply bearing on the bottom of the housing, main fixed contacts and a fixed contact arc.
  • the fixed contact area is arranged in front engagement. In other words, it consists of a relatively straight metal bar, which does not impose a curved path to the current flowing therethrough and therefore prohibits any electromagnetic loop effect on the incipient bow when opening.
  • the movable contact member comprises a conductive fixed current-carrying pad also bearing on the bottom of the housing, and a contact system having a plurality of identical main contacts, divided into two series of the same number of parts and of another of a movable arc contact extending longitudinally along the median axis of the pole.
  • the arc contact protrudes into the chamber and allows entry of the arc into the chamber.
  • the arc extinguishing chamber is disposed above the first range and comprises lateral flanges supporting a stack of separators constituted by metal sheets of deionization of the arc, each sheet having a V-shaped notch. lower bow horn and an upper bow horn frame the stack of sheet metal from the extinguishing chamber.
  • the upper bow horn has two side tabs that are folded towards the fixed contacts and partially seal the upper part of the entrance into the chamber.
  • a lateral arc guiding cheek In the contact separation zone in the extension of each of the two side flanges of the chamber, there is a lateral arc guiding cheek.
  • the two cheeks protrude obliquely towards each other from the plane of the corresponding flange.
  • the cheeks have a substantially trapezoidal shape and are located in the lower part of the chamber, close to the fixed contact. They limit in the lower part access to the chamber, near the lower bow horn. When opening the contacts, the guide cheeks allow centering of the root arc along the lower arcuate horn.
  • Such a chamber is particularly suitable for circuit breakers of high caliber, of the order of 3000 A, having to satisfy single-phase voltage breaking tests.
  • relatively high of the order of 600 V with a relatively low intensity, of the order of 5 to 10 times the rated current of the circuit breaker.
  • it is poorly adapted to the breaking of very high fault currents, of the order of 100kA, at a moderately high voltage of 480V.
  • the intensity of the breaking current is very high, the diameter of the section of the arc is important, so that the arc is born almost instantaneously on all the contact fingers and immediately occupies the entire the available volume of the room.
  • the chamber is then subjected to a very high pressure and a very high temperature.
  • the gas emission of the cheeks further contributes to increase the pressure. But the positioning of the cheeks and the upper bow horn helps to reduce the opening of the entrance to the chamber, resulting in a delay in the balancing of the pressures in the housing of the device, which can lead to explosion of it.
  • circuit breaker arc chamber described in US Pat. No. 4,650,938, comprising separators intended to be arranged close to the contacts, and a pair of lateral flanges arranged on either side of a terminal block.
  • median longitudinal plane of the chamber to support the separators.
  • Each flange has an elongate rib projecting towards the opposite flange.
  • the two ribs extend over the entire height of the chamber, perpendicular to the separators, and face each other. They are arranged between the separators and the contacts, so as to restrict the width of the opening of the chamber entrance uniformly over the entire height of the chamber.
  • the ribs modify the gas flow in the chamber, and protect the portion of the flanges supporting the separators of the hot gas flow.
  • Such an arrangement is useful for a low performance low-end circuit breaker, in order to prevent the flanges from being damaged by the heat of the arc gases. By cons, it does not allow to use the entire volume of the chamber to cool the gas. The dimensions of the chamber needed to dissipate the energy of a given arc power, will be more important.
  • a circuit breaker of this type requires that arrangements be made to facilitate entry of the arc into the chamber, and in particular that the fixed contact is U-shaped under the lower surface of the chamber, to create an electromagnetic loop effect favoring the entry of the arc into the chamber.
  • the invention therefore aims to improve the performance of a high-voltage low-voltage multipole circuit breaker equipped with an upper arc horn. It aims in particular to allow the cutting of arcs large diameter arcs generated by very high fault currents at medium voltages, avoiding the risk of explosion of the chamber.
  • the arc horns help to ensure the entrance of the arc into the chamber as soon as the head of the main electric arc switches on the upper arc of the bow, even if the contact pads are of the type taken before , without electromagnetic effect of loop on the arc.
  • the dielectric shields allow them to lengthen and bend the electric arc between the movable contact in the open position and the separators, so as to promote the switching of the arc on the upper arc horn.
  • the narrowing of the dielectric screens in the lower part of the chamber, near the fixed contact allows to obtain a wide opening of the entrance to the chamber, which promotes the balance of pressures between the chamber and the previous volume of the pole.
  • the upper arc horn has a free end located near the movable contact member in the open position, and interposed between the separators and the movable contact member in the open position.
  • the upper part of each side dielectric screen interposes between the separators and the free end of the upper arc horn. This positioning of the upper bow horn allows for optimal switching of the bow on the upper bow horn. Dielectric screens are an obstacle for the arc. The arc is obliged to circumvent them to reach the separators, which allows its elongation.
  • the side dielectric screens are made of a low-gas-generating material, especially a polytetrafluoroethylene or a polyamide 6-6 or 4-6 heavily loaded.
  • the screens do not help to increase the pressures in the room. In addition, they do not generate a flow of gas likely to hinder the entry of the arc into the chamber.
  • each dielectric screen has an upper part and a lower part substantially narrower than the upper part. Alternatively, it is possible to totally eliminate the lower part.
  • each dielectric screen has an anterior part, the anterior parts of the two dielectric screens flanking at least partially the contact zone.
  • the front parts of the screens act as a protective shield for the side wall of the pole.
  • a low-power multipole circuit breaker 10 comprises a molded insulating casing 12 enclosing a known type of control mechanism 14, provided with a transverse switching bar 16 common to all the poles, journalling in bearings housed in the housing 12.
  • Each pole comprises a fixed contact member 20, a movable contact member 22 and an arc extinction chamber 24 located near the fixed contact member 20.

  • the arc voltage U B is high enough to prohibit its regeneration. The current is cut.
  • the maximum pressure reached in the chamber requires a considerable strengthening of the walls of the chamber to prevent an explosion of the device.
  • the early rise of the arc voltage U B is useless for a device with little limiter, since the essential thing is to have a sufficiently large arc voltage at the time of the passage of the current by zero.

However, the maximum value is identical to that of the previous test and is maintained until the passage of current by zero, so that at this moment, the arc goes off permanently.
  • the dielectric screens are not very gasogenic, so as to control the pressure rise in the chamber. However, it may be useful in certain configurations, to provide dielectric screens in a gasogenic material. On this point there is a compromise to be made between the ultimate breaking power of the circuit breaker and its performance in the other breaking tests, especially during tests at high voltage and low current.
