Abstract
The invention relates to a compressed gas circuit-breaker with a tubular stationary contact, a tubular moving contact, a device for inserting a resistance when the circuit-breaker closes, the insertion device and the resistance being disposed in a coaxial casing, said device being controlled by the moving contact of the circuit-breaker, the insertion device (19) being of the semi-mobile type and having a first means (51, 52) for damping its closing and a second means (50, 44) for delaying its opening when the circuit-breaker opens, wherein the first means (51, 52) and the second means (50, 44) are of the type which operate by pressure reduction. Application to circuit-circuit breakers which equip very high tension lines.
