Claims (1)

[Claims for Utility Model Registration] (1) A ratchet gear that is rotatably supported by 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 the ratchet gear. A cam provided on the side surface and rotating integrally with the ratchet gear, a slider provided slidably on the frame and used to turn on and off the handle of the circuit breaker or disconnector, and a roller provided on the slider and engaged with the cam. a closing spring that presses and biases the slider toward a position where the handle is in an on state, and a switch for the electric motor;
a stop actuation lever rotatably supported by the slider and actuating the switch when the slider moves to a position where the handle is turned off; and a stop operation provided on the cam to actuate the stop actuation lever. It has a pin and a latch mechanism that holds both the slider and the closing spring in the loaded position, and when the electric claw drives the ratchet gear, the slider is moved by the cam via the roller and the closing spring is moved. is stored,
When the handle is switched to the off position due to the movement of the slider, the stop operation pin rotates the stop operation lever to operate the switch, and the latch mechanism holds the slider and the closing spring is in the charged state. is held in
Then, when the stored 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 the stop operating lever separates from the stop operating pin and the switch. An electric operating device for a circuit switch or breaker, characterized in that the ratchet gear is divided into an inner ring part on the center side and an outer ring part on the outer peripheral side, and the two are connected by an elastic body such as elastic rubber. electrical control device for the device. (2) Electrical operation of a circuit breaker as claimed in claim 1 of the utility model registration claim, characterized in that the elastic body is an elastic rubber ring, which is press-fitted between the inner ring and outer ring of a ratchet gear. Device. (3) The electric operating device for a circuit or breaker according to claim 1, wherein the inner ring and outer ring of the ratchet gear are integrally molded from elastic rubber.
