Claims

[Scope of utility model registration request]

(1) A movable member for operating a movable contact is housed in a closed metal tank so as to be able to reciprocate, a proximity sensor is fixed to either the inner wall of the metal tank or the movable member, and the other is
A gas insulated switchgear having a stroke device, characterized in that it is provided with means for varying the output of the proximity sensor as the movable member moves.

(2) A gas insulated switchgear having a stroke device according to claim 1, wherein the output variation means of the proximity sensor is obtained by tilting the wall surface of a metal tank or the surface of a movable member facing the proximity sensor.

(3) Utility model registration claim 1, in which the output variation means of the proximity sensor is a plurality of notches provided at predetermined intervals on the wall surface of the metal tank or the surface of the movable member facing the proximity sensor.
A gas insulated switchgear having a stroke device according to paragraph 1.
