What is a vacuum circuit breaker?

"Vacuum circuit breaker" is named for its high dielectric energy due to its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing; it has the advantages of small size, light weight, suitable for frequent operation, and no need for overhaul of arc extinguishing. The application in the power grid is more popular. The vacuum circuit breaker is an indoor power distribution device in a 3~10kV, 50Hz three-phase AC system, which can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants and substations, especially suitable for oil-free and less For maintenance and frequent operation, the circuit breaker can be configured in the central cabinet, double cabinet, and fixed cabinet for controlling and protecting high voltage electrical equipment.
