摘要
基于前期实验取得的良好效果,利用静电屏蔽原理,结合供电隔离、线路屏蔽及套管接地等技术,对重庆地震局钻孔应变观测台站进行了防雷技术改造,取得明显效果,达到了降低钻孔应变观测系统雷击故障率的目的;从实践效果看,地震台站防雷是一项科学、严谨的系统工程,防雷改造过程中必须要综合考虑,注重每个细节,才能达到良好的防雷效果。
Applied with principle of electrostatic shielding,the technologies of power isolation,cable shield and casing ground electrode,Earthquake Administration of Chongqing borehole strain observation site has made a great achievement on lightning protection technology,which meets the goal that the accident rates is lowered.In practical,lightning protection in seismic station is a scientific and rigorous projict,which every detail in transformation should be seriously considered so as to achieve the lightning protection goal.
