Abstract
In order to solve the above-described problems, a gas circuit breaker of the present invention has an insulating nozzle disposed so as to cover an inner surface of a coupling member such that an end surface of the coupling member and an end surface of the insulating nozzle form one surface (the end surface of the coupling member is flush with the end surface of the insulating nozzle), in order to suppress contact between a high-temperature and high-pressure gas generated by an arc and the coupling member coupling the insulating nozzle and a driving rod.
