Dustproof high-voltage vacuum circuit breaker

Abstract

The invention discloses a dustproof high-voltage vacuum circuit breaker, which comprises a box body. A support plate is arranged inside the box body; a circuit breaker main body is fixedly connected to the top of the support plate; both sides of the box body communicate with a connecting tube; an electrostatic dustproof net is fixedly connected to each of the two sides on the top of the support plate; and a first electric telescopic rod is fixedly connected to each of the two sides on the top of the inner cavity of the box body. In the invention, an effect of placing the circuit breaker main body is achieved through the arrangement of the box body; an effect of absorbing the dust is achieved through the electrostatic dustproof nets; an effect of driving a brush to move is achieved throughthe first electric telescopic rod; an effect of cleaning the dust on the electrostatic dustproof nets is achieved through the brush; an effect of cleaning the dust in the box body is achieved throughthe connecting tube and a fan; and an effect of sealing the connecting tube and filtering the dust is achieved through a baffle plate and a filtering net. The circuit breaker can shield the dust effectively and brings convenience for people to use.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breakers, in particular to a dust-proof high-voltage vacuum circuit breaker. Background technique [0002] Vacuum circuit breaker is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. Vacuum circuit breakers are widely used in industrial and mining enterprises, power plants, and substations as protection and control of electrical equipment. They are especially suitable for places that require no oil, less maintenance, and frequent operations. The circuit breaker can be configured in Central cabinets, double-deck cabinets, and fixed cabinets are used to control and protect high-voltage electrical equipment, while the existing vacuum circuit breakers will be exposed to the air for a long tim...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a dust-proof high-voltage vacuum circuit breaker, which has the advantages that the vacuum circuit breaker will not be exposed to the air for a long time and will not adhere to a large amount of dust when the vacuum circuit breaker is in use. When in use, it will be exposed to the air for a long time, and there will also be a problem of a large amount of dust sticking
