Opening-closing operation control device and circuit breaker

Abstract

The invention relates to the technical field of circuit breakers, and discloses an opening-closing operation control device. The opening-closing operation control device comprises a shell, a motor, a driving gear, a handle gear, a handle turntable and a release lever; a pressure block on the end face of the driving gear can be matched with one end of the release lever, the handle turntable is used for setting a handle inner shaft, a handle connecting rod of the handle turntable is positioned in an accommodating groove of the handle gear, the motor rotates in one direction, the handle gear drives the handle turntable to rotate to realize automatic closing, the motor rotates reversely to drive the handle gear to return to the initial position, and the handle turntable can rotate freely in the accommodating groove to realize manual opening and closing; the motor further rotates reversely, and the pressure block can drive one end of the release lever, and a release linkage shaft drives a release linkage mechanism inside a circuit breaker to release so as to realize automatic opening and keep the opening state. The circuit breaker can realize the functions of automatic opening and closing, manual opening and closing after automatic closing, failure in manual closing after automatic opening and the like, and is simple in structure, good in opening and closing synchronization and quick in opening.

Description

technical field [0001] The present invention relates to the technical field of circuit breakers, in particular to an opening and closing operation control device, and a circuit breaker with the opening and closing operation control device. Background technique [0002] With the development of technology, the power consumption of daily life and production is increasing. Correspondingly, in order to ensure the safety of power consumption, circuit breakers with automatic opening and closing functions are more and more widely used in smart grids. , such as self-resetting overvoltage and undervoltage protectors and prepaid reclosing circuit breakers, etc., can realize remote control of circuit breaker opening and closing. [0003] However, in practical applications, when the automatic recloser drives the handle of the circuit breaker to close or open through its own operating handle, the phenomenon of asynchronous reclosing of the circuit breaker often occurs, especially in multi...

Problems solved by technology

[0003] However, in practical applications, when the automatic recloser drives the handle of the circuit breaker to close or open through its own operating handle, the phenomenon of asynchronous reclosing of the circuit breaker often occurs, especially in multi-pole open circuits. This will cause the circuit breaker of the last pole to fail to close normally, and the circuit cannot be connected, which will cause a large circuit failure or safety hazard

[0004] In addition, in some applications, it is necessary to meet the requirement that the switch cannot be closed manually after opening, and the control motor can automatically close the switch after receiving the control command. However, such automatic reclosing devices often have artificial The situation of manual closing, resulting in some users not paying for electricity
