Claims

[Scope of utility model registration request]

a container filled with a gas having arc-extinguishing properties, a pair of contacts disposed opposite to each other in the container, which can be moved into and out of contact, an arc running plate provided near one of the contacts of the pair, and one of the contacts. and a magnetic drive coil that is provided to surround the contactor and has one end electrically connected to the arc running plate, and the arc is driven to the arc running plate by the rotational force given by the magnetic flux generated from the magnetic drive coil. In a gas breaker that extinguishes an arc by rotating along the arc, a pressure chamber provided on the one contactor side, and a space surrounded by the magnetic drive coil and the arc traveling plate inside the one contactor. A gas circuit breaker, comprising: a communication path that communicates between the pressure chamber and the pressure chamber.
