What is Vacuum interrupter

The contact opening distance is small, the contact opening distance of 10KV vacuum interrupter is only about 10mm, the operation work of the operating mechanism is small, the mechanical part stroke is small, and its mechanical life is long.

The vacuum interrupters should be checked and maintained once a year to ensure normal operation.

The main structure of the vacuum circuit breaker consists of a vacuum interrupter, an operating mechanism and an insulating support base frame, etc.

The vacuum circuit breaker breaks the current and extinguishes the arc in the vacuum bubble, and the vacuum circuit breaker itself does not have a device for qualitatively and quantitatively monitoring the characteristics of the vacuum degree, so the vacuum degree reduction fault is a recessive faul......

When using the high-voltage vacuum circuit breaker, in order to better exert the corresponding performance, it is necessary to understand the corresponding characteristics.
