Vacuum circuit breaker mainly contains three parts

Vacuum breaker mainly consists of three parts: vacuum interrupter, electromagnetic or spring operating mechanism, support, and other components

Editor features

1) small contact, 10 kV Vacuum circuit breaker contact only from about 10 millimeters, high voltage vacuum circuit breaker operation mechanism of operation power is very small, the mechanical part is small, the machine service life is long.

(2) the arc time is short, independent of the switch current size, usually only half of the cycle.

(3) the rapid recovery of the contact gap between the back arc media and the splitting of the vicinity of the fault is better.

(4) as a result of dredging, when the break off current is small, so contact electrical life long, open circuit 30 to 50 times full capacity, rated current open more than 5000 times, noise is very small, suitable for frequent operation.

5. Small in size and light in weight.

6. Capacitive load current for open circuit.

Because of its many advantages, it is widely used in substations, the current model mainly includes: ZN12-10, ZN28A - 10, ZN65A - 12, ZN12A - 12, VS1, ZN30, and so on.
