An opening and closing transmission device with clutch function and a circuit breaker thereof

Abstract

The invention discloses an opening and closing transmission device with a clutch function, and a breaker. The device includes a shell, and a driving motor, a breaker handle mechanism and a gear transmission mechanism that are arranged in the shell, and a shifting lever switching structure; the shifting lever switching structure comprises a shifting lever part and a linkage part, the linkage part can move between the first driven gear and the second driven gear in a cooperated reciprocating telescoping mode under the driving of the shifting lever part, and has a first position state enabling the first driven gear and the second driven gear to form a coaxial linkage fit, and a second position state enabling the first driven gear and the second driven gear to release the linkage relation. Theshifting switching structure can overcome the problem that the breaker handle cannot be shifted due to clamping and blocking, manual and automatic mode switching can be truly realized without being controlled by an external power supply, the control system is simplified, the manufacturing cost is saved, the use is convenient, and the usability of the product is improved.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to an opening and closing transmission device with a clutch function and a circuit breaker thereof. Background technique [0002] With the promotion of the smart grid, the use of electric energy metering devices such as IC card prepaid meters is becoming more and more popular. The circuit breaker that needs to be manually operated can no longer meet the requirements of the smart grid. Therefore, it is necessary to match the circuit breaker specially used by the prepaid meter The circuit breaker product can realize automatic reclosing operation, transmit a control signal, and then realize remote control, so that the circuit breaker can be automatically closed or opened, without the need for staff to manually open and close, effectively saving manpower and material resources . [0003] The existing reclosing device used in conjunction with the circuit breake...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the problem that when the circuit breaker and the opening and closing device are used together in the prior art, once the system is powered off, the gears are stuck to each other, so that the handle of the circuit breaker is blocked and cannot be moved, and the existing clutch mechanism has poor reliability. , the action is easy to fail, and there are defects of potential safety hazards, so as to provide a safe and reliable opening and closing transmission device with clutch function, which is simple in structure, and the handle of the circuit breaker can be freely toggled back to its position in the power failure state.
