调度台雷击事故分析及整改措施

Analysis and Rectification Measures for the Lightning Accidents of Dispatcher Station

当建筑物遭受雷击时,强大的雷电流及其产生的空间电磁脉冲将对室内的电子设备造成干扰,容易引起电子设备工作失灵或者损坏,导致通信故障。文章在分析某公司一年中连续发生2次因雷击造成调度台故障的基础上,重点研究雷电感应对室内电子设备的影响,提出针对性的防雷措施,以减少雷击对电网通信的影响。

When a building is struck by lightning, the indoor electronic equipment will be disturbed by powerful lightning current and spatial electromagnetic pulse generated by the lightning current, which will bring about the malfunction and damage for electronic equipment easily, leading to communication failure. On the basis of analyzing the breakdown of dispatcher station caused by lightning strike occurred twice in a year in our company, this paper puts emphasis on studying the influence of lightning induction on indoor electronic equipment. In addition, this paper proposes some lightning-protection measures to reduce the affects of lightning on the power grid communication system.
