What are the functions of vacuum interrupter?

Vacuum interrupter, also known as vacuum switch tube, is the core component of medium and high voltage power switch. Its main function is to quickly extinguish the arc and suppress the current after the medium and high voltage circuit cuts off the power supply through the excellent insulation of vacuum in the tube, so as to avoid accidents and accidents. It is mainly used in power transmission and distribution control system, as well as metallurgy, mining, petroleum, chemical industry, railway Distribution systems such as broadcasting, communication and industrial high-frequency heating. It has the characteristics of energy saving, material saving, fire prevention, explosion-proof, small volume, long service life, low maintenance cost, reliable operation and no pollution. The vacuum interrupter is divided into interrupter for circuit breaker and interrupter for load switch. The interrupter for circuit breaker is mainly used for substation and power grid facilities in power department, and the interrupter for load switch is mainly used for end users of power grid.
