Vacuum circuit breaker is named because its arc extinguishing medium and the insulating medium in the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, lightweight, suitable for frequent operations, and no maintenance required for arc extinguishing. It is widely used in power grids. Vacuum circuit breaker is an indoor power distribution device in a 3-10kV, 50Hz three-phase AC system. It can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is especially suitable for oil-free and low-voltage applications. In places of maintenance and frequent operations, circuit breakers can be configured in central cabinets, double-layer cabinets and fixed cabinets to control and protect high-voltage electrical equipment.
