摘要

The invention relates to a circuit breaker has a high voltage and a compressed gas, a maneuvering energy assisted by the thermal effect of the arc and a double movement, comprising a moving assembly carrying the main contacts and of the arcing contacts and electrically connected to a first electrical socket, a fixed assembly connected to a second electrical connector of the circuit breaker, a semi - mobile assembly is connected electrically to the fixed assembly and bound mechanically to the fixed assembly by means of a subject of the main contacts and of the arcing contacts cooperating respectively with the main contacts and the arcing contacts of the mobile assembly characterizes in that it comprises means 13, 36 in order to exert, during an interruption arc of a force on the whole arrangement - wheel 20 in order to tend to remove it in the direction opposed to the displacement of the moving assembly 40. p / p applications to the circuit breakers a sulphur hexafluoride.
