Claims

[Scope of utility model registration request]

(1) A fixed contact part and a movable contact part placed opposite to the fixed contact part so as to be able to move toward and away from the fixed contact part are provided in a container filled with arc-extinguishing gas. The compressed gas in the buffer sill is sprayed onto the arc between the surface contacts in conjunction with the opening operation of the movable arc contact, and an insulating nozzle arranged to wrap around the movable arc contact is attached to the middle part of the outer periphery of the insulating nozzle. The insulating nozzle is fixed to the buffer cylinder via a mounting member that engages with the buffer cylinder, one end is fixed near the outer peripheral tip of the insulating nozzle so as to surround the outer periphery of the mounting member, and the other end is fixed to the inside of the insulating nozzle with the mounting member. An insulating cover stretched out with a predetermined gap through which arc-extinguishing gas flows in and out is attached, and the mounting member is provided with a current-carrying contact portion on the outer peripheral surface near the base of the mounting member, and the tip of the mounting member is connected to the A buffer type gas breaker, characterized in that the buffer type gas breaker is located closer to the fixed contact portion than the current carrying contact portion.

(2) The buffer type gas breaker according to claim 1, wherein the current-carrying contact portion is constituted by a separate member from the mounting member. S) The buffer type gas breaker according to claim 1, wherein the current-carrying contact portion is made of the same member as the mounting member.
