AUTOMATIC CLOSING DEVICE AND METHOD OF VACUUM CIRCUIR BREAKER IN CASE OF FAILURE RECOVERY BY DISTRIBUTION LINE

摘要

The present invention relates to an automatic input device and a method of a vacuum circuit breaker in repairing a distribution line fault. The present invention comprises: a relay state detection unit (10) for detecting a relay state value; a voltage current measurement unit (20) for measuring a current value and a voltage value of a distribution line; a central processing unit (30) for receiving a relay state value detected by the relay state detection unit (10), to determine a power outage or power recovery state, receiving the current value and the voltage value measured by the voltage current measurement unit (20) to determine whether or not there is an accident inside or outside, and outputting a circuit breaker control signal by determining a distribution line fault and a distribution line restoration; and a VCB control unit (40) for controlling the vacuum circuit breaker according to the circuit breaker control signal of the central processing unit (30). According to the present invention, the power outage time can be shortened by quickly recovering in the event of a power outage due to a distribution line fault, and the safety of workers can be ensured during power outage recovery.
