ABSTRACT:
The invention relates to a double-acting, compressed gas, high tension circuit breaker in which the operating energy is assisted by the thermal effect of the arc, the circuit breaker comprises a moving assembly having main contacts and arcing contacts which is electrically connected to a first electrical connection point, a fixed assembly connected to a second electrical connection point of the circuit breaker, and a semi-moving assembly which is electrically connected to said fixed assembly and which is mechanically linked to said fixed assembly by resilient means, said semi-moving assembly having main contacts and arcing contacts which co-operate respectively with the main contacts and the arcing contacts of the moving assembly, the circuit breaker further including means (13, 36) for exerting a force on said semi-moving assembly (20) when an arc is being interrupted in order to displace the semi-moving assembly in the opposite direction to that in which the moving assembly (40) is displaced.
