Problems solved by technology

[0002] The actuator of the circuit breaker in the prior art has many parts and complex structure, especially the cost of parts and processing is high
In addition, in the prior art, the push plate is always in contact with the actuator during the action of the actuator unit. The actuator needs to overcome the action of the push plate. The demand for the force value of the actuator is high, the volume of the actuator is large, and the service life is short.
The existing technology has a low degree of modularization and is difficult to process and manufacture

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0029] see Figure 1 to Figure 3 , The actuator reset device provided by the present invention includes an actuator 4 , a rotating plate 6 , a rotating plate reset torsion spring 5 , a push rod 7 and a push rod return spring 8 . The actuator 4 is fixed in the housing 1 to receive the tripping command and issue an execution action. Usually, the actuator cannot automatically reset after receiving the tripping command. The actuator reset device provided by the present invention can solve this problem. The rotating plate 6 is arranged in the housing 1 and rotates around an axis. The rotating plate 6 pushes the actuator 4 to move when rotating so as to realize the reset of the actuator. The rotating plate return torsion spring 5 is connected (contacted) with the rotating plate 6 to reset the rotating plate 6, and keeps the rotating plate 6 in a s...

Abstract

According to an executing mechanism resetting device, the rotating plate is rotatably arranged in the shell, the executing unit is installed in the shell, when a circuit breaker is opened, a main shaft of a circuit breaker operating mechanism rotates to push the push rod, in this way, the push rod slides in the shell and is in lap joint with the rotating plate so as to push the rotating plate to rotate in the shell, and the rotating plate drives the driving ejector rod to do linear motion while rotating so that resetting can be completed. According to the executing mechanism resetting device, the structure is simple and compact, the modularization degree is high, the part cost and the machining cost are greatly reduced, according to the new scheme, when the executing unit of the executing mechanism is tripped, the push plate is far away from the executing unit, extra resistance is not generated on the executing unit, and therefore, the force value required by the execution unit in the execution mechanism is small, and the service life of the execution mechanism is greatly prolonged.

Description

technical field [0001] The invention relates to a circuit breaker device, in particular to an actuator of the circuit breaker. Background technique [0002] The actuator of the circuit breaker in the prior art has many parts and complex structure, especially the cost of parts and processing is high. In addition, in the prior art, the push plate is always in contact with the actuator during the action of the actuator unit. The actuator needs to overcome the action of the push plate. The demand for the force value of the actuator is high, the volume of the actuator is large, and the service life is low. The prior art has a low degree of modularization and is difficult to process and manufacture. Contents of the invention [0003] The invention provides a reset device for an actuator with a simple and compact structure and convenient processing. [0004] In order to achieve the purpose of the present invention, a reset device for an actuator provided by the present inventio...
