Claims

[Scope of claim for utility model registration] (1) Storing the opening/closing part together with insulating gas inside the tank,
An operating mechanism unit that drives the movable side of the opening/closing unit is disposed adjacent to the tank and communicated with an insulating gas, and a buffer device is further disposed at an end of the operating mechanism unit in communication with an insulating gas. In this shock absorber, a piston connected to an operating rod of the operating mechanism section, which is connected to a movable side of the opening/closing section via an insulating rod, is inserted into a chamber formed at an end of the operating mechanism section. , in which a buffer member made of an elastic member is disposed at the end of the reciprocating stroke of the piston that slides inside the chamber, the strain that alleviates the compressive strain that occurs when the piston collides with the buffer member. Relief part 2: = I, , f: (2) Strain relief part of a gas insulated switch characterized by having a plurality of ring-shaped relaxation parts each having a different diameter fitted so as to form a gap between them. A shock absorbing device for a gas insulated switch as set forth in claim 1 of the utility model registration claim. (3) A shock absorbing device for a gas insulated switch according to claim 1, wherein the strain relief portion is formed by a plurality of grooves or a plurality of holes provided in a plate-shaped shock absorbing member.
