江苏省数字地震台站防雷改造工程效果分析

Effect Analysis of Lightning Protection Alteration of Digital Seismic Stations in Jiangsu Province

介绍了雷电对数字化地震观测台站的危害和2010年江苏地震局防雷改造工作采取的方式,并统计防雷改造的效果,总结了改造工作中成功的经验与不足,并提出了建议。地震台站防雷是一项系统工程,需要从接地、配电系统、观测系统、通信系统、综合布线综合考虑,并结合台站自身特点做针对性防护。

The paper introduces the lightning damage to the digital seismic observation stations, and the methods of lightning protection alteration took by Earthquake Administration of Jiangsu Province in 2010, statistics the effect of lightning protection alteration, summaries the experience and deficiency of the work, and puts forward suggestions to the deficiency. Lightning protection alteration of the digital seismic observation stations is a system engineering, which needs comprehensive consideration from the ground, power distribution system, monitoring system, communication system, integrated wiring, and targeted protection combined with the characteristics of seismic stations.
