Claims

[Scope of utility model registration request]

(1) In a gas insulator type breaker consisting of a fixed electrode and a movable electrode arranged so as to be able to approach and separate from each other in an insulator tube, a drive piston connected to the movable electrode via a contact drive shaft is connected to the movable electrode. A damper piston is provided that is integrated and protrudes toward the movable electrode, and a concave portion is formed on the outer periphery of the damper piston.On the other hand, a recessed portion is formed on the movable electrode side of the cylinder in which the driving piston is reciprocatably housed.
A cylinder block in which the damper piston fits is formed inside the cylinder block, a locking device is disposed in the cylinder block, and the locking device is a chamber partitioned into the inside and outside by a locking rod having a T-shaped cross section; It is characterized by being formed by a spring that presses the tip of the locking rod toward the concave portion of the damper piston, and a compressed air supply pipe communicating with the chamber on the opposite side of the locking rod. Gas insulator type breaker.

(2) The gas insulator type circuit breaker according to claim 1, wherein a plurality of locking devices are disposed in the cylinder block.
