助電極を設けてなるガス遮断器。[Claims for Utility Model Registration] An arc extinguishing device comprising an annular magnetic field generator disposed in an insulating gas atmosphere and having a coil, and an annular arc runner located on one side of the magnetic field generator and connected to one end of the coil. a fixed contact arranged near the hollow part of the arc extinguishing device on the arc runner side of the arc extinguishing device and connected to the other end of the coil, and a movable contact that contacts the fixed contact so as to be able to freely approach and separate. a contactor, the arc generated by the opening of both the contacts is transferred from the fixed contactor to the arc runner, the arc current is commutated to the coil, and the arc is caused by the magnetic field of the magnetic field generator. A gas circuit breaker configured to extinguish an arc by rotating at high speed outside the hollow part using electromagnetic force, wherein an auxiliary electrode having approximately the same potential as the fixed contact is provided in the hollow part.
