Basic function analysis of high voltage vacuum circuit breaker

1. Current limiting and breaking
When a short circuit occurs in the circuit system, the high-voltage vacuum circuit breaker will react quickly and open the contacts. The main function of the contacts is to limit the subsequent increase in current and reduce the incidence of subsequent failures.
2.Short circuit protection
The meaning of short-circuit protection is relatively simple. It is somewhat similar to the operation of an ordinary switch. Mainly when a high-voltage current passes through the circuit and creates a short circuit, the high-voltage vacuum circuit breaker trips instantly to achieve the purpose of protecting the circuit system.
3. Overload delay protection
Each device has its own corresponding upper limit of carrying current. If this upper limit is exceeded, the device may burn out. The function of the high-voltage vacuum circuit breaker is to detect that when the upper limit of current is exceeded, it cuts off the current source in a very short time to protect electrical equipment.
4.Isolation
Isolation means that after the high-voltage vacuum circuit breaker disconnects the current, it can also lock the current within the circuit system, and will not cause damage to other surrounding equipment or even personnel due to current leakage.
