High voltage circuit breaker detection:
① Reliable operation: When the circuit breaker operates under the technical conditions given by the manufacturer, it should be able to operate normally and reliably for a long time ② It should have sufficient breaking capacity: due to the high voltage and current of the power grid, when the circuit breaker disconnects the circuit, an arc will appear between the contacts. Only by extinguishing the arc can the circuit be disconnected. Therefore, it is required that the circuit breaker has sufficient breaking capacity, can reliably cut off short-circuit current, and ensure sufficient thermal and electric stability ③ With the shortest possible cut-off time: When a power grid fault occurs, the circuit breaker is required to quickly cut off the faulty circuit, which can shorten the fault time of the power grid and reduce the damage of short-circuit current to electrical equipment
