ABSTRACT:
An insulator-type gas circuit interrupter which comprises a movable contact and a stationary contact for closing and separating a main circuit and an insulator tube in which an arc-extinguishing chamber of a frustoconical configuration is defined. The movable contact is disposed in the frustoconical arc-extinguishing chamber at its smaller inner diameter side, and the stationary contact is disposed in the frustoconical arc-extinguishing chamber at its larger inner diameter side. An electrically insulating gas is sealed inside of the frustoconical arc-extinguishing chamber.
