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。本文分析雷电的形成、雷击的种类和雷电对数字化前兆地震台站的危害,从配电系统防护、信号线路防护、屏蔽措施和布线防护、接地与等电位连接、雷电预警、防雷装置维护与管理6个方面对台站雷电防护进行探讨,在实际地震监测中取得较好效果,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。
Thunderstorm Hazard is one of the important factors affecting the stable operation of seismic stations, which is of great significance to the station lightning protection. This article analyzes the formation of thunder and lightning, the type of lightning and the damage of lightning to digital precursor seismic stations. From the perspectives of distribution system protection, signal line protection, shielding measures and wiring protection, grounding and equipotential bonding, lightning warning, lightning protection device maintenance Management of six aspects of lightning protection station to discuss in the actual earthquake monitoring to achieve better results, which can effectively reduce the damage caused by lightning, in particular, to reduce lightning damage to the instruments and equipment of the earthquake observation technology system.
