Abstract

The invention discloses an electric operating mechanism of a circuit breaker, which relates to the field of circuit breakers. The electric operating mechanism of the circuit breaker comprises a shell, a motor, a gear set connected with the output end of the motor, a coupler, an operating handle and a tripping mechanism, wherein the gear set comprises a handle gear in transmission connection with the motor, and the coupler is relatively and fixedly connected with the operating handle; the handle gear is installed on the coupler in a hinged mode and provided with a gear boss extending out in the radial direction, and the coupler is provided with a check block which corresponds to the gear boss and is in contact fit with the gear boss. The handle gear has a first state in which the operating handle is driven to be switched on through forward rotation of the motor and contact cooperation of the gear boss and the stop block when the handle gear is at the initial position, and a second state in which the handle gear returns to the initial position through reverse rotation of the motor when the handle gear is switched on. The mechanism has the advantages of being small in occupied space and reasonable in layout.

Description

technical field [0001] The invention relates to the field of circuit breakers, in particular to an electric operating mechanism of a circuit breaker. Background technique [0002] As a switch that can provide various protection functions, the circuit breaker can effectively improve the safety and reliability of electrical equipment and power lines. In order to meet the increasingly diverse needs of users, the specification diversification and miniaturization of circuit breakers is a trend; at present, circuit breakers that can realize remote opening and closing control generally adopt the internal assembly and linkage method of 18mm circuit breakers and 18mm electric operating mechanisms. To realize the remote automatic opening and closing control of the product, the electric operating mechanism needs to be placed separately at a height of 18mm, which occupies a large volume and has a complex structure, which cannot meet the miniaturization requirements of the circuit breake...
