摘　　要：高山雷达站雷电地电位反击是一个容易被忽视的雷击事故隐患,事故主要特征是弱电系统设备大面积设备信号端口损坏,主要原因是雷达站场地面积小,弱电系统独立接地装置安全距离不够,采取埋地线路屏蔽措施是一个妥当的解决方法。The counterattack of lightning ground potential in high mountain radar station is an easily overlooked hidden danger of lightning. The major feature of the accident is large-area equipment signal port damage in weak current system equipment. The main reason is that the radar station site area is small, and the safety distance of the independent grounding device of weak current system is not enough.It is a proper solution to take underground line shielding measures.
