[0003] "High-voltage vacuum circuit breaker" is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. The application in the distribution network is relatively popular. The existing high-voltage vacuum circuit breakers have slow action speed, complex structure, small contact pressure, and no self-locking function.
