Claims

[Scope of utility model registration request]

(1) In a tank filled with an arc-extinguishing gas such as SFe gas, a fixed conductor section having a fixed contact section, and a movable conductor section consisting of a movable contact section and a gas compression mechanism directly connected to it. The movable contact part and the buffer sill of the gas compression mechanism are connected to the tip of a hollow operation pipe, and this operation pipe is interlocked with the external drive part via an insulating iron, and the inside is connected from the tip side of the operation pipe. In a buffer type gas breaker configured to discharge gas flowing into the operation pipe from the operation pipe, a connecting iron having an outer diameter smaller than the inner diameter of the operation pipe is inserted into the insulated iron side end of the operation pipe, The proximal end of the connecting rod is fixed to the tip of the insulating iron, and the operating pipe and the connecting rod are connected via a plate-like member arranged radially between the inner surface of the operating pipe and the outer periphery of the connecting rod. A buffer type gas breaker featuring:

(2) The buffer type gas breaker according to claim 1, wherein the connection between the operating pipe and the connecting rod is made by welding.
