DGVZ-15/27KV
DGG
The working principle of high-voltage automatic reclosing is mainly based on the nature of faults in the power system, most of which are instantaneous or temporary, such as surface flashover of insulators caused by lightning, and discharge of branches on the line. When these faults occur, the relay protection device will quickly activate, causing the circuit breaker to trip and cut off the power supply. Then, after a predetermined time interval, if the fault has been automatically eliminated, the automatic reclosing device will cause the circuit breaker to close again, thereby restoring power supply. This process reduces power outage time and improves the reliability of power supply. If the fault is persistent, such as line tripping, short lines, etc., the circuit breaker will trip again and no longer overlap to prevent further damage to the equipment.
