An operating mechanism of a circuit breaker for an inflatable cabinet

Abstract

The invention discloses an operating mechanism for a circuit breaker of an inflatable cabinet, which comprises an operating casing. A fixed mandrel is fixed on the inner side wall of the operating case. The mandrel is equipped with a chute plate and a grooved plate. The grooved plate is equipped with an inner groove slide bar. The inner groove slide bar is fixedly connected with one end of the slide bar plate, and the other end of the slide bar plate is fixedly connected with the cam rocker. In the middle of the rod, one end of the cam rocker is connected to the large spindle boss, the other end of the cam rocker is connected to the front end of the closing spring mechanism, and the other end of the closing spring mechanism is connected to the small spindle boss, and the cam rocker is equipped with a manual The cam and the motor cam, the motor cam is fixedly linked to the motor turbine, the motor turbine is equipped with a motor worm, the motor worm is fixed on the shaft of the energy storage motor, and the cam rocker is equipped with a spring buckle. The operating mechanism of the circuit breaker of the inflatable cabinet of the present invention ensures safety through button-type operation, and at the same time, the number of parts is small.

Description

technical field [0001] The invention relates to the field of gas-filled cabinet devices, in particular to an operating mechanism of a gas-filled cabinet circuit breaker. Background technique [0002] The inflatable cabinet is a new generation of switchgear. The main switch can use either a permanent magnet mechanism vacuum circuit breaker or a spring mechanism vacuum circuit breaker. The whole cabinet is combined with air insulation and sulfur hexafluoride gas compartment, which is both compact and expandable. , suitable for distribution automation. In the field of high-voltage vacuum circuit breakers, the use of spring operating mechanisms has become more common. The demand for high-capacity and generator circuit breakers continues to increase; correspondingly, spring-operated mechanisms are also used in generator circuit breakers. [0003] The current operating mechanism of the circuit breaker of the gas-filled cabinet generally uses the knob when the worker opens and cl...
