摘要

通过对典型形变台站遭雷害的调查，指出形变台站受雷害或干扰的途径是：（１）雷击避雷针的雷电过电压和大电流；（２）交流供电线路上的雷直击过电压与感应过电压等。在分析和归纳后针对性地提出并实践了：（１）应用半导体少长针消雷器防直击雷害；（２）建立接地地网和设计过压保护单元电路或雷击期启用ＵＰＳ以防电子设备的感应雷害；（３）对架空供电进线换用埋地金属外皮屏蔽电缆以防线路来波侵入等综合治理措施，收到了显著的社会和经济效益。
Through investigation on the typical deformation seismostation which are damaged by lightning, two ways of lightning damage are pointed out in the paper:(1) The overvoltage and large current formed when lightning strikes lightning rod; (2) The overvolotage of supply power lines formed in the direct hits or induction of lightning. After analysis and summary, the measures are presented and applied as follows:(1) Establishing the semiconductor lightning eliminator to prevent the direct lightning; (2) Improving grounding mesh and adding overvolotage protection circuits or supplying power by UPS in process of lightning; (3) Changing overhead supply power lines into power cables with metal shield buried in ground. It has been proved that the measures are very effective.
