Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a novel outdoor vacuum circuit breaker. Background Art

[0002] "Vacuum circuit breaker" is named because 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 arc extinguishing without maintenance, and is widely used in distribution networks. Vacuum circuit breaker is an indoor power distribution device in 3~10kV, 50Hz three-phase AC system. It can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is particularly suitable for use in places that require oil-free, less maintenance and frequent operation.
