Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a column type vacuum circuit breaker. Background Art

[0002] The name of the vacuum circuit breaker is derived from the fact that both its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum. The vacuum circuit breaker has the advantages of small size, light weight, suitable for frequent operation, and no maintenance required for arc extinguishing. It is widely used in distribution networks; the vacuum circuit breaker is an indoor distribution device in a 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. The circuit breaker can be configured in a central cabinet, a double-layer cabinet, and a fixed cabinet to control and protect high-voltage electrical equipment.
