Abstract

The invention relates to a clutch for controlling on-off with a power supply. The clutch for controlling on-off with the power supply comprises an output shaft arranged on a inner rotating frame of a case body, a ratchet wheel and a cam are fixed on the output shaft, and the excircle of the ratchet wheel is provided with an arc groove; a mounting shaft is fixed on the cam, a pawl support is rotatably arranged on the mounting shaft, and a clutch shaft is fixed on the pawl support; the clutch shaft and the arc groove of the ratchet wheel excircle are selectively coordinated, a torsional spring is arranged on the mounting shaft, and the torsional spring presses the pawl support to ensure the clutch shaft to be embed in the arc groove of the ratchet wheel excircle; and a driving device which enables the pawl support to rotate around the mounting shaft on the cam so as to cause the clutch shaft in the arc groove and the arc groove to deviate, is arranged in the box,. The clutch provided bythe invention has the advantages that the arc groove ratchet wheel has high intensity and is meshed with the clutch shaft reliably, the pawl support and the ratchet wheel are move synchronously without sound, the pawl support and the cam are installed into a whole, and the synchronizing precision is high.

Description

technical field [0001] The invention relates to an electric operating mechanism, in particular to a clutch with power supply control on-off. Background technique [0002] As the core power part of the circuit breaker, the electric operating mechanism is widely used in various circuit breaker industries. Its main function is to convert electrical energy into mechanical energy to provide power for the closing and opening (energy storage) of the circuit breaker. In the event of a power outage or damage to the backup power supply, the circuit breaker needs to be manually opened for closing and opening. During manual closing and opening, the motor and the circuit breaker are not separated, which increases the difficulty of manual energy storage. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a clutch with power control on-off that can realize clutching and synchronously control power on-off. ...
