输电线路末端设备的雷击损坏及保护措施

THUNDERSTROKE DAMAGE AND PROTECTING MEASURES OF END EQUIPMENT OF POWER LINE

通过高压线路末端悬空系统因雷击引起过电压而损坏线路末端设备的事故，分析了雷电波在输电线路中的传播过程，提出了在输电线路末端加装避雷器以保护线路末端设备的安全有效措施。

Based on an accident which overvoltage is produed by thunderstroke in the end hung system of high-voltage line to cause damage to the line end equipment, the authors analyze the propagation of lightning wave in the power line,and put forward the effective safe measures which the lightning arrester is installed at the power line end to protect the end equipment.
