Claims

[Scope of utility model registration request]

(1) The arc generated between the contacts of the breaker part during the breaker operation is extinguished by being blown through the compressed gas insulated nozzle in the buffer sill and exhausted through at least the inner diameter of the movable arc contactor. In the buffer type gas circuit breaker, the movable arc contact has a surface substantially parallel to the operating direction of the movable member at the inner diameter thereof, and the inner diameter expands toward the downstream side at a portion downstream of the surface from the surface. A first inclined part is provided, and in an open state, the inner diameter of the downstream end of the first inclined part is approximately equal to the inner diameter of the upstream end of a finger support that supports the movable arc contactor extending downstream. A buffer type gas breaker characterized in that it is configured to have a second inclined part whose inner diameter expands toward the downstream side of the finger support 5.

(2) In the open state, the first sloped part of the movable arc contact and the second sloped part of the finger support are arranged in a substantially straight line. Buffer type gas breaker described in section 1).
