Abstract

The invention relates to the technical field of low-voltage circuit breakers, and discloses a driving and tripping structure for an electric operating device of an intelligent circuit breaker, which includes a driving motor and a base, and the base is provided with a base groove, a transmission gear, a connecting rod, a driving gear, a driving rod, and a guide Rod and trip lever, the rotating shaft of the drive motor is meshed with the transmission gear through the worm; the transmission gear is meshed with the drive gear, one end of the connecting rod is connected with the drive gear through the matching hole, and the guide rod is provided with a waist hole. The other end of the connecting rod is installed in the waist hole; the trip lever is coaxial with the drive gear, and the guide rod is coaxially connected with the drive rod through the drive shaft; the circuit breaker handle is connected with the drive shaft and rotates synchronously with the drive shaft. The invention can realize that when the tripping part is not reset, it can avoid the damage of the internal parts by human operation, can realize the functions of remote opening, closing and tripping, and can perform operation switching, realize manual / automatic operation, and facilitate remote control and on-site maintain.

Description

technical field [0001] The invention relates to the technical field of low-voltage circuit breakers, in particular to a driving and tripping structure of an electric operating device of an intelligent circuit breaker. Background technique [0002] Common automatic closing and opening devices of circuit breakers are driven by a motor gear system to increase the output torque of the motor and reduce the speed to provide power for closing and opening of the circuit breaker. During the user's use, the circuit breaker products are closed and opened according to the instructions output by the user, and the remote control is realized through the communication function. The automatic closing and opening device of the circuit breaker drives the circuit breaker mechanism to close through the gear mechanism. Since the internal transmission gear adopts a linkage structure, when the remote closing is not in place, due to the one-way transmission of the worm, it cannot be manually closed,...
