The invention discloses a circuit breaker electric operating mechanism of a flat structure. The circuit breaker electric operating mechanism comprises an enclosure, wherein one side of the enclosure is provided with a flat motor; an output shaft is arranged in the enclosure; the output shaft is connected with a one-way engaging and disengaging gear which is in transmission connection with the flat motor; the one-way engaging and disengaging gear comprises a main gear, a pawl, a spacing shaft, a microswitch, an output shaft sleeve and a control cam, wherein the output shaft sleeve and the control cam are independently fixedly arranged on the output shaft; the control cam is provided with a first bayonet; the output shaft sleeve is provided with a second bayonet; a dialing button of the microswitch is matched with the first bayonet; the main gear is sheathed on the output shaft sleeve; the pawl is arranged on the main gear; the inner end of the pawl is matched with the second bayonet on the output shaft sleeve; and the spacing shaft is fixedly arranged on the inner wall of the enclosure. The electric operating mechanism can cooperatively work with the microswitch on the basis of the one-way engaging and disengaging gear in the circuit breaker electric operating mechanism so as to realize the accurate control of the circuit breaker.
Description
technical field [0001] The invention relates to a circuit breaker electric operating mechanism with a flat structure. Background technique [0002] As the core component of remote and intelligent control of various circuit breakers, the known electric operating mechanism not only needs to realize reliable electric operation, but also ensures manual operation of the circuit breaker. During electric operation, the electric operating mechanism runs in place, and the micro switch acts to cut off the power supply of the motor. However, due to the inertia of the motor, the continuous operation of the electric operating mechanism will cause a certain impact on the circuit breaker. During manual operation, since manual operation and electric operation share the same transmission system, during manual operation, not only the resistance on the circuit breaker mechanism itself must be overcome, but also the resistance of the motor in the electric operation mechanism (to drive the moto...
