1. Introduction to high voltage vacuum circuit breaker:
The high-voltage vacuum circuit breaker is named because its arc-extinguishing medium and the insulating medium in the contact gap after arc-extinguishing have high vacuum degrees; it has the advantages of small size, light weight, suitable for frequent operations, and no maintenance required for arc extinguishing. It is widely used in power distribution and online applications are relatively common.
The high-voltage vacuum circuit breaker is mainly composed of three parts: a vacuum arc extinguishing chamber, an electromagnetic or spring operating mechanism, and a bracket.
2. Energy storage and manual opening of high-voltage vacuum circuit breaker:
1. High voltage vacuum circuit breaker energy storage:
Turn on the auxiliary power switch in the intelligent control unit to charge the battery in the intelligent control box. If the battery is fully charged, you can turn on the battery switch in the smart control box. Wait 20 seconds. At this time, the energy storage capacitor is charged and the circuit breaker is ready to operate.
2. Manual opening operation of high-voltage vacuum circuit breaker:
When the vacuum circuit breaker is in the closed position, use the insulated operating rod to hook the pull ring on the manual opening handle of the circuit breaker and pull it downward. The circuit breaker can break and still has a certain breaking speed to ensure that the circuit breaker can reliably break the rated load current.
