浅谈静电屏蔽原理在钻孔应变仪防雷中的应用

摘要

Applied with principle of electrostatic shielding , the technologies of power isolation , ca-ble shield and casing ground electrode , Earthquake Administration of Chongqing borehole strain ob-servation 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 a-chieve the lightning protection goal .%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。
