High-voltage vacuum switches are not the same as high-voltage vacuum circuit breakers.
A high-voltage vacuum switch is a functional switch with strong arc quenching capability, long electrical life, long maintenance cycles, minimal operation and maintenance workload, fire and explosion prevention, and stable performance. A high-voltage vacuum circuit breaker, on the other hand, is a device with both protective and control (switching) functions. In the event of a fault, it automatically trips to disconnect the circuit, thereby protecting the safety of both the circuit and equipment.
