瞬时性故障主要是指由雷电引起的绝缘子表面闪络、线路对树枝放电、大风引起

Instantaneous faults mainly refer to short circuits caused by lightning flashover on the surface of insulators, discharge of lines to tree branches, short-term touches caused by strong winds, and discharges through bird bodies. After the instantaneous fault is disconnected from the power supply by the relay protection action, the arc at the fault point is automatically extinguished, the insulation strength is restored, the fault is eliminated, and the circuit breaker automatically recloses to restore normal power supply.

瞬时性故障主要是指由雷电引起的绝缘子表面闪络、线路对树枝放电、大风引起的短时碰线、通过鸟类身体的放电等原因引起的短路。瞬时性故障由继电保护动作断开电源后，故障点的电弧自行熄火、绝缘强度重新恢复，故障自行消除，线路断路器自动重合闸恢复正常供电。

Transient fault mainly refers to the short circuit caused by lightning flashover on insulator surface, line to branch discharge, short-time line contact caused by strong wind, discharge through bird body, etc. After the instantaneous fault is disconnected by the relay protection action, the arc at the fault point will automatically extinguish, the insulation strength will be restored, the fault will be eliminated automatically, and the automatic reclosing of the line breaker will restore the normal power supply.<br>
