Definitions

  • the present invention relates to a dual-chamber compression-breaking chamber and a power circuit breaker comprising such a current-breaking chamber.
  • Circuit breakers using a so-called “auto-blow" breaking chamber perform a compression of a dielectric gas, making it possible to blow an arc that is formed between arcing contacts during a power failure operation, or operation of opening of the circuit breaker.
  • the compression is generally performed by an operating member, which may be a spring mechanism coupled to a motor, actuating a movable part, such as a piston, in the breaking chamber.
  • These circuit breakers also utilize the energy provided by the arc as heat, thereby decreasing the external power consumption compared to conventional gas compression circuit breakers.
  • the energy supplied by the arc is much less important than when the current is a strong current, and if moreover the the duration of the arc is long (between about 15 and 20 ms), the external power consumption required for the blowing of the arc then becomes too great.
  • the purpose of the present invention is to provide a breaking chamber, used in particular in a power circuit breaker, for cutting currents as strong as weak, while avoiding unnecessarily increasing the external energy consumption by the device. maneuver, whatever the duration of the arc.
  • the present invention proposes in claim 1 a current-breaking chamber, which can be used in a circuit-breaker, filled with a dielectric fluid comprising a movable assembly moving axially between a start position and an end position of power failure operation, or opening operation of the circuit breaker.
  • the moving assembly comprises at least a first compression chamber whose volume decreases between the opening operation opening position of the circuit breaker and a compression end position of the first chamber, at least a first arcing contact, intended to cooperate with a second arcing contact, the two arcing contacts being axially movable relative to each other.
  • the movable assembly also comprises at least one second compression chamber, communicating at a first end with the first compression chamber, the volume of which decreases between the starting position of maneuver, that is to say the starting position of circuit breaker opening operation, and the end-of-circuit breaker opening operation position, for injecting dielectric fluid into the first compression chamber, between an open position of the circuit breaker, and first chamber and the end position of opening operation of the circuit breaker, when the pressure in the first compression chamber is lower than the pressure in the second compression chamber.

  • the second compression chamber makes it possible to maintain the blowing of the arc, initially produced by the first compression chamber, for the duration of the arc. arc, and that avoiding excessive external energy consumption through the use of the energy provided by the arc during the entire duration of the blowing.

  • the current interruption chamber may also comprise means immobilizing the piston between the opening operation opening position of the circuit breaker and the compression end position of the first chamber. Thus, by remaining stationary between these two positions, the piston reduces the volume of the first compression chamber and thus compresses the dielectric fluid present in the first compression chamber.
  • the means immobilizing the piston may comprise at least one housing for receiving a stop, for example a ball, connected to the piston.
  • the current cut-off chamber may also comprise means axially displacing the piston with the moving assembly between the compression end position of the first chamber and the end-of-circuit opening position of the circuit breaker.
