Abstract This paper combines a case of a circuit breaker trip of a high-voltage reactor in a substation and looks for it from three aspects of primary equipment, secondary equipment, and protection principles. Due to the long service life of the equipment and the frequent opening and closing of the high-voltage reactor circuit breaker during maintenance, Causes circuit breaker spring weakness and high-voltage reactor interturn protection trip. By adjusting the spring compression of the circuit breaker to meet the requirements of the circuit breaker's switching characteristics, it provides a reference for the field personnel to operate and maintain the old equipment, analyze and deal with similar failures, avoid such events, and ensure normal power transmission.

Key words： high-voltage reactor circuit breaker zero sequence protection spring compression switching characteristics
