しゃ断器の手動操作装置。A control box with a door that can be opened and closed on the front side and installed with a gap between it and the ground surface is connected to a movable contact of the breaker housed in the control box and connected to a fixed contact. It is equipped with an operating valve that switches and transfers pressure oil to a hydraulic cylinder that controls the operating valve, and a solenoid valve that is installed on the operating valve and has a plunger end for manual operation that is covered with a gate-shaped cover and has a protruding plunger end. , the electromagnetic valve is pivotably supported on the gate-shaped cover of each of the solenoid valves, one end is engageable with the plunger end, the other end projects toward the front side, and is normally biased by a spring toward the anti-engagement side. a vertical operating lever that is pivotably guided, one end of which is engageable with the lower surface of the front end of the operating lever, and the other end of which extends through the lower wall of the control box; A spring-biased manual is connected to the other end of the operating lever via a crank for changing direction, and engages the front end of the operating lever of the solenoid valve with the vertical lever by pulling from the front side of the control box. A manual operating device for a hydraulically operated breaker, characterized by comprising a handle.
