摘要： A medium-, high-, or very high-voltage circuit breaker (10), comprising at least one arc-control chamber (12) and an outer casing (14) in which the arc-control chamber (12) is arranged. In the invention, the circuit breaker includes sealing ring (52) for sealing an opening (50) in a discharge cap (40) of the arc-control chamber (12), the ring (52) being movable between a sealing position and a retracted position in which they allow the gas to pass, the circuit breaker being configured in such a manner that in the closed position, the sealing ring (52) are in their retracted position, and in such a manner that passage from the retracted position to the sealing position takes place during an operation of opening the circuit breaker.

摘要： The invention relates to a medium-, high-, or very high-voltage circuit breaker, comprising at least one arc-control chamber and an outer casing in which the arc-control chamber is arranged. The circuit breaker includes a discharge cap (40) forming a portion of the outer wall external of the arc-control chamber (12), the discharge cap being situated inside the outer casing and internally defining a gas-flow chamber (31). In the invention, the discharge cap (40) includes at least one portion (40′) that is movable under the effect of the gas pressure in the gas-flow chamber (31), in such a manner that its volume is extensible.

摘要： A nozzle with an electric arc-blast having a median part of a first dielectric material and two end parts. The nozzle includes an insert of a second dielectric material, chosen from among: a composite material including a fluorocarbon polymer matrix and inorganic filler A chosen from among a sulfur, a ceramic and an oxide (SiO2, TiO2, Al2CoO4, ZnO, BaTiO3 and P2O5), in a percentage weight ranging between 0.1% and 10%, and/or at least one inorganic filler B (a graphite, a mica, a glass and a fluoride), in a percentage weight ranging between 5% and 50%, and a ceramic material including compound(s) (a carbide, a boride and an oxide).
