Definitions

  • the invention relates to arc extinguishing chambers of circuit breaker-type protection devices with high breaking performance. More generally, the invention relates to a closure system for cooling and filtering gases from an electric arc, but discharging said gases in a differentiated manner depending on the magnitude of the fault and the pressure thus generated.
  • High-voltage low-voltage circuit breakers most often have separable contacts arranged at the entrance of an arc-extinguishing chamber: during the separation of the contacts caused by a trigger following an overcurrent, an electric arc arises between contacts and propagates in the arc extinguishing chamber intended to absorb the energy of the arc while maintaining its voltage.
  • the quenching chamber comprises a plurality of separators arranged transversely to the arc and intended to split it; this fractionation makes it possible to increase the voltage of the arc and to cool it by heat exchange with the separators, which are supported by two lateral walls of the chamber arranged facing each other, perpendicular to the separators.
  • the chamber is subjected to very high thermal, mechanical and electrical stresses: a current of 200 kA maintained for 4 ms at a voltage of arc of 500 V thus releases an energy of 400 kJ, the plasma column forming the arc can reach a temperature between 3500 and 20000 ° C, and the pressure in the extinguishing chamber can simultaneously reach 1.4 MPa.
  • the generated overpressure is transmitted to the circuit breaker box, and various means have been put in place to respond to this constraint.
  • circuit breakers have filtration systems for cooling and deionizing the gases from the arc to ensure a secure external environment.
  • the filtration system conventionally comprises, as for example described in US 7,176,771 or FR 2 788 372 , quiches and watertight passages to force the gases to circulate there; corollary, sealing means retain the gases inside the housing until the filtration is not performed.
  • circuit breakers with extreme performance can see the residual pressure inside their housing become very important: for example, for a circuit breaker displaying a three-phase performance of 200 kA 508 V, a performance of 174 kA 508V single phase is required by ANSI standards, and the pressure generated may be greater than 14 bar.
  • the filtration systems hardly withstand beyond 14 bar, in addition to a possible explosion of the housing, breakage or tearing of the seals, which implies an uncontrolled flow of gases and therefore a danger for an operator and a risk boot.
  • the invention aims to overcome the disadvantages of existing arc extinguishing chambers.
  • the invention proposes to maintain a gas filtration passage while providing a solution when the internal pressure becomes too great for a molded case circuit breaker.
  • the invention relates to a circuit breaker with a housing for at least one separable contact pole in which a breaking chamber can be placed, or any other external wall allowing a closure of said housing: the housing opens out of the housing of the circuit breaker by at least two partitions provided with a flange on which the outer wall or an outer wall of the interrupting chamber can rest.

  • the wall is associated with a valve device at its opposite surface.
  • the valve device comprises at least two lips protruding out of the opposite surface at the sides intended to be placed on the edges of the housing.

  • the valve device is monobloc, and comprises a membrane pierced with at least one central passage opening cooperating with the gate, and a periphery whose two opposite sides form the lips while the other two sides serve as a seal. seal.
  • the lips are made of insulating material, preferably a polymer, which is resistant to heat and to sudden increases in temperature, especially at temperatures of more than 2000 ° C. or even 3500 ° C. during minus 5 ms, preferably at least 10 ms.
  • the lips have a mechanical strength to maintain the valve device substantially flat along the opposite surface and on the edges of the housing despite the cantilever ; the lips are such that no significant deformation is caused by a pressure orthogonal to the opposite surface less than a first threshold, preferably of the order of 3 bars, or even 7 and even 10 bars.
  • the mechanical strength is such that, when the outer wall is placed on the edges of the housing and the pressure is exerted from the bottom of the housing, the lip is lifted uniformly, to abut against the part of the housing. protruding end without further deformation of the valve device; advantageously, the cantilever is sufficient so that, in the open position, the lip is always projecting relative to the end portion.
  • at least the lips are made of aramid fibers which are very resistant to heat and flame, in particular polyaramide with phenyl groups in meta, in particular Nomex® 410.
  • the outer wall may be part of an arc extinguishing chamber, being orthogonal to a set of parallel arc separators and two lateral retaining cheeks at which the valve lips are located.
  • the width defined between the lateral cheeks is less than the width of the intermediate portion, so that the space between the housing and the outer wall is successively decreasing and increasing.

  • the invention relates to an outer wall of an arc extinguishing chamber, adapted to rest on two flanges of a switchgear housing housing, comprising a rigid closure grid of the housing whose cut orthogonal to the closure surface of the housing comprises an end portion that can rest on the projecting flanges with respect to an intermediate portion that can be inserted into the space defined by said flanges, and a valve device coupled to the grid at level of intermediate part projecting on at least two sides by lips which can rest on said flanges, wherein said lips of the valve device are made of insulating material, resistant to heat, and a mechanical strength such that the lip is substantially rigid and flat when it is subjected to an orthogonal pressure less than a first threshold pressure, in particular 10 bar, and the lip deforms reversibly when the orthogonal pressure is greater than a second threshold pressure, in particular 10 bar.
  • the lips are made of polyaramid that can withstand temperatures above 2000 ° C. for at least 5 ms, especially with separation of amides by meta-phenylene groups.

  • a device with contact pressure springs 36 is disposed in a notch of the cage 30 and urges the contact fingers 24B pivoting about the first axis 28.
  • the cage 30 is coupled to the switching shaft 22 by a link rod / link assembly 38 so that the rotation of the shaft 22 induces a pivoting of the cage 30 around the axis 34.
