Abstract:
This gas circuit breaker (1) is provided with: a tank (2) in which an insulating gas is sealed; a fixed contactor (4) fixed on the central axis (N) of the tank (2); a movable contactor (3) capable of reciprocating between a position when making contact with the fixed contactor (4) on the central axis (N) and a position when separated from the fixed contactor (4); a cooling tube (6) which covers around the fixed contactor (4) and through which the insulating gas for arc-extinguishing can flow; and an insulating tube (8) which is attached to an end of the cooling tube (6) in a first direction parallel to the central axis (N), into which the insulating gas from the cooling tube (6) can flow, and which is made of an insulator. The length of the insulator in a second direction vertical to the central axis (N) is longer than the length of the cooling tube (6) in the second direction.
