Claims

[Claims for Utility Model Registration] (1) A ratchet gear that is rotatably supported on a frame, an electric claw that is driven by an electric motor to rotate the ratchet gear, a fixed claw that prevents the ratchet gear from reversing, and a ratchet gear that rotates on the frame. a manual operating lever supported on the frame and driven by a manual operating handle; a manual claw provided on the manual operating lever for rotating the ratchet gear; and a manual operating lever provided on a frame for positioning the manual operating lever. a stopper, a cam provided on the side surface of the ratchet gear to rotate integrally with the ratchet gear, a slider provided slidably on the frame to turn on/off a handle of the circuit or disconnector, and a slider provided on the slider. a roller that engages with the cam; a closing spring that presses and biases the slider toward a position where the handle is in an on state; a switch for the electric motor; and a switch rotatably supported by the slider and with the handle in an off state. a stop operation lever that operates the switch when the slider moves to a position where , and a stop operation pin that is provided on the cam and operates the stop operation lever;
It has a latch mechanism that holds both the slider and the closing spring in the energized position, and when the ratchet gear is driven by the electric motor or the manual operation handle, the slider is moved by the cam via the roller, and the slider is moved by the cam via the roller. When the closing spring is energized and the slider moves to switch the handle to the off position, the stop operation pin rotates the stop operation lever to operate the switch and the slider is held by the latch mechanism. When the closing spring is held in a stored state, and the loaded force of the closing spring is released, the slider moves in the opposite direction to the moving direction to switch the handle to the on position and at the same time closes the stop operating lever. In the electric operating device for a circuit or disconnection, in which the lever is detached from the stop operation pin and the switch, at least a stopper portion of the manual operation lever stopper is made of an elastic body such as elastic rubber, and when the ratchet gear is reversed, the fixed An electrical operating device for a circuit or disconnection device, characterized in that the manual pawl engages with the ratchet gear before the pawl engages with the ratchet gear. (2) The electrical circuit breaker according to claim 1 of the utility model registration claim, characterized in that the manually operated lever stopper is composed of an elastic rubber plate constituting the stopper portion and a replaceable spacer. Operating device.
