The basic working mode of intelligent circuit breaker

The basic working mode of the intelligent circuit breaker is: when the system fails, the relay protection device sends a disconnection signal or the operator sends an operation signal, and the intelligent identification module is first started to judge the current state, that is, the working condition of the circuit breaker, and adjust the adjustment. The device sends out different quantitative control information and automatically adjusts the relevant parameters to obtain the motion characteristics suitable for the current system working state, and then makes the circuit breaker act. Its core is to automatically select the parameters of the operating mechanism and the pre-specified working conditions of the arc extinguishing chamber according to the different fault currents monitored, and disconnect at low speed when the current is small, and disconnect at high speed when the current is large, so as to obtain the best electrical and mechanical performance.
