Research on the Anti Misoperation Device of Grounding Switch in Ring Network Cabinet

In view of the problem of misoperation of the ring cabinet, which is easy to occur in the electrical operation of the distribution network at present, this paper develops an anti-misoperation device of the ring cabinet grounding switch, which has the "five prevention" logic judgment to assist the distribution network switch to prevent misoperation. The device adds intelligent locks to optimize the management of traditional distribution network locks, and studies the operating environment before manual operation to improve the level of anti-error operation. Field experiments show that the accuracy of the device is 99.86%, which can reduce the risk probability of misoperation and ensure the safe and reliable operation of distribution network.
