摘　　要：雷电危害是影响地震台站稳定运行的重要因素之一,对台站进行雷电防护具有重要意义。从讨论雷电对地震台站造成的危害出发,分析雷电入侵地震台站前兆设备的途径,阐述综合防雷系统的构成与基本要求,从配电系统、通信和信号线路、地网改造、线路电磁屏蔽等多个方面提出地震台站防雷的有效措施,可以有效减轻雷灾损失,特别是减轻雷电对地震观测技术系统仪器设备的损害。Lightning hazard is one of the most important factors that affect the stable operation of seismic stations. The paper discusses the lightning hazards of seismic stations, analyzes the lightning invasion pathways precursory observation devices of seismic stations, and explains a comprehensive lightning protection system and the basic requirements. Meanwhile, the paper puts forward effective measures for lightning protection of seismic stations from the aspects of distribution system, the communication and signal line, network reconstruction,electromagnetic shielding line, which can effectively reduce disaster losses, and in particular, reduce lightning damage on seismic observation system equipment.
