Description

Technical Field

[0001] This utility model relates to the field of vacuum circuit breaker technology, and in particular to an outdoor automatic reclosing permanent magnet vacuum circuit breaker. Background Technology

[0002] Outdoor automatic reclosing permanent magnet vacuum circuit breakers are named for their high vacuum nature, which is both the arc-extinguishing medium and the insulating medium in the contact gap after arc extinguishing. They have the advantages of small size, light weight, suitability for frequent operation, and no maintenance required for arc extinguishing. They are widely used in power distribution networks and can be used in industrial and mining enterprises, power plants, and substations for the protection and control of electrical equipment. They are particularly suitable for applications requiring oil-free operation, minimal maintenance, and frequent operation.

[0003] However, in the existing technology, it has been found that some outdoor automatic reclosing permanent magnet vacuum circuit breakers used outdoors do not have rainproof measures. When it rains, corrosive substances in the rainwater come into contact with the outdoor automatic reclosing permanent magnet vacuum circuit breaker. Over time, the corrosive substances in the rainwater may corrode the outdoor automatic reclosing permanent magnet vacuum circuit breaker, which may reduce its service life. Utility Model Content
