Abstract
Disclosed is a spring energy storage type circuit breaker contactor no-voltage and closing malfunction detection method. The method is characterized by comprising the following steps of a, detecting a control loop, b, detecting an operation fuse protector, c, detecting a control circuit breaker contact, d, detecting an auxiliary circuit breaker normally-closed contact and e, detecting a tripping prevention relay normally-closed contact. According to the portion likely to malfunctions, the probability of malfunction generation and the maintenance complexity degree, the detection method can rapidly detect the malfunctioning portion, repair the malfunctioning portion in time and rapidly recover normal operation of a power grid.
Description
Technical field
The present invention relates to spring energy-storage type breaker contacts device no-voltage, switch failure fault detection method, belong to isolating switch maintenance technique field.
