浙江岛屿深井地震台防雷接地系统设计

针对当前岛屿深井地震台设备容易遭雷击及维修不便等问题，通过对雷电入侵台站设备的途径分析，依据现有防雷技术规范和相关理论，对观测房和井口防雷接地采用法拉第笼结构预防雷击，加强接地等电位连接，规范各种线路布设，综合多级雷电防护措施，使岛屿深井地震台站稳定可靠运行。

Design of lightning protection and grounding system for the islands of Zhejiang deep seismic stations

For the problems that the deep-well seismic equipment on the islands is easily struck by lightning and difficult to be repaired conveniently,with the analysis on the path of lightning intruding the stations equipment and the existant technology on lightning protection and relevant theories,we suggest applying Faraday cage structure to the observation room and the wellhead to prevent lightning,strengthening the grounding equipotential bonding,specifying various line layout and integrating multi-stage lightning protection measures,in order to make sure the deep-well seismic stations on the islands work steadily and reliably.
