Closing resistors play an irreplaceable role in limiting the over - voltage caused during the interruption of circuit breakers. Since closing resistors endure high heat energy in a short time, malfunctions often occur due to excessively high temperatures. Given that it is difficult to measure their working states, it is of great significance to simulate and analyze the working states of closing resistors under different working scenarios. Based on the parameters provided by the closing resistor manufacturer and self-measured parameters, and according to the recorded wave signals during a certain closing resistor fault process, this paper constructs a simulation model for the working state of the closing resistor and conducts a simulation analysis. The results of the simulation analysis are basically consistent with the fault process shown by the recorded wave signals, verifying the correctness of the simulation model constructed in this paper.
