Reclosing apparatus of circuit breaker

Abstract

The invention relates to a reclosing apparatus of a circuit breaker. The reclosing apparatus comprises a pedestal, a top cover, a transmission mechanism, an intelligent control circuit board and a release mechanism; the transmission mechanism comprises a driving handle, a motor, a worm and a gear assembly; the gear assembly comprises a balance wheel, a rotating shaft and a semi-gear; one side, corresponding to the driving handle, of the intelligent control circuit board is provided with a first hall sensor; the semi-gear is provided with a first induction piece cooperating with the first Hall sensor; the other side, corresponding to the driving handle, of the intelligent control circuit board is provided with a second hall sensor; the balance wheel is provided with a second induction piece cooperating with the second Hall sensor; the intelligent control circuit board controls forward rotation, stopping and backward rotation motions of the motor, and drives motion of the transmission mechanism to realize an automatic reclosing motion of the circuit breaker; and the intelligent control circuit board controls motion of the release mechanism to realize an automatic opening motion of the circuit breaker. The reclosing apparatus of the circuit breaker has the advantages of simple structure, stable and reliable performance and long service life.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a reclosing device of a circuit breaker. Background technique [0002] Miniature circuit breakers are widely used in low-voltage power distribution networks, mainly in various places such as industry, commerce, high-rise buildings, and residential buildings. They can provide overcurrent protection and leakage protection for electrical equipment such as motors, distribution lines, and lighting circuits. With the development of my country's smart grid, under the premise of requiring the safe operation of the grid, it is more and more urgent to realize the intelligent control of electrical appliances. In order to cope with new changes in the situation, the existing miniature circuit breakers are equipped with reclosing devices, but the reclosing devices of the existing miniature circuit breakers have complex structural design, high production costs, unstabl...

AI Technical Summary

Problems solved by technology

In order to cope with new changes in the situation, the existing miniature circuit breakers are equipped with reclosing devices, but the reclosing devices of the existing miniature circuit breakers have complex structural design, high production costs, unstable performance, and use The defect of short life, when the circuit breaks down and requires the small circuit breaker to trip quickly, the transmission mechanism of the reclosing device is not sensitive, which greatly affects the normal opening and closing of the circuit breaker, thus causing serious safety hazards and cannot guarantee the user's power consumption Safety
