遮断器。 It has a fixed contact element and a movable contact element that can be separated, and an insulating nozzle provided to surround the movable contact part, and is connected to the movable contact element to an arc generated between the two contact elements when current is interrupted. In a gas circuit breaker that extinguishes an arc by spraying arc-extinguishing gas compressed by a cylinder and a piston through the insulating nozzle, when the pressure in the cylinder chamber surrounded by the cylinder and the piston exceeds a certain level, the cylinder A gas circuit breaker characterized by being provided with a valve that opens in a direction different from the direction in which arc is generated from the chamber.
