Claims

[Scope of utility model registration request]

A buffer cylinder is housed in a grounded metal container and has a movable contact that advances and retreats in a straight line to make contact with and separate from a fixed contact.A hollow metal tube that is connected along the axis and has an exhaust port on the wall is connected to an insulating rod. a fixed piston defining a buffer chamber between the coupled operation rod and the buffer sill, and a cylindrical cylinder having a contact portion that slides on the outer circumferential surface of the buffer sill at an end on the fixed contact side. A buffer type gas circuit breaker comprising a current collector formed in the shape of a shape, and a fixed support part that supports the current collector and the fixed piston from the metal container via an insulator, wherein the current collector is discharged from the operating rod. A shielding part is formed inside the fixed support part so as to shield the insulator from the exhaust gas, and a space is formed between the cylindrical current collector and the exhaust gas flowing outside the fixed support part. A buffer type gas cutoff, characterized in that the fixed support part is provided with a through hole that communicates between the inside and the outside of the fixed support part, and the collector is provided with an exhaust port that communicates with the internal space of the metal container. vessel.
