摘　　要：因雷电导致的地震台站观测系统瘫痪以及设备损坏产生的经济损失已成为影响地震台站长期稳定运行的重要因素之一。针对地震台站观测系统电子特性通过雷电表现形式对雷击成因进行分析并找出原因。根据地震台站布设的地理、地质特点及其重要性,按照国家防雷相关规范要求做出了地震台站的防雷类别划分即二类防雷类别。运用综合雷电防护技术措施从直击雷防护、雷电感应防护、等电位连接、综合布线及屏蔽、接地装置等技术措施对地震台站观测系统进行了防雷设计和施工技术要求的论述。The lightning-caused paralyses of observing systems in seismic stations and the economic losses which caused by equipments' damage have become two important factors affecting the long-term stable operation of seismic stations. Thanks to the electronic features of observing systems in seismic stations and lightning manifestations, this essay, by which, have found out the causes and reasons. According to the geographical, geological characteristics and importance, this essay, followed by some relevant regulations, have divided the lightning protection into two types, ln order to discuss the designs and technical requirements of constructions of the observation system, the author have used most of the lighting-proof technologies, such as, direct lightning protection, lightning sensor system, equipotential connection, wiring and shielding, earthing devices and other technical measures.
