摘　　要：地震监测台站观测设备长期面临雷击风险。雷击事件一旦发生,将对监测站的正常运行造成严重干扰。2021年6月7日—8日,海南省儋州市西流地下流体观测站连续2次遭受雷击,造成巨大损失。经现场调查,对受损元件和设备进行深入分析,研究雷击侵入路径和方式。结果表明,2次雷击事件均由通信网络端感应引发,是网络通信线路感应引起的典型感应雷击事件。The observation equipment of earthquake monitoring stations is exposed to the risk of lightning strike for a long time.Once lightning strikes occur,it will cause serious interference to the normal operation of the monitoring station.From June 7 to 8,2021,the Xiliu Underground Fluid Observation Station in Danzhou City,Hainan Province,was struck by lightning twice in a row,causing huge losses.Through the field investigation,analysis was conducted on the damaged components and equipment to study the path and method of lightning intrusion.The results indicate that the 2 lightning strikes were caused by the communication network terminal induction,which are typical induced lightning strikes caused by network communication line induction.
