提高地电观测线路抗漏电影响的有效途径

AN EFFECTIE WAY IMPROVING ON RESISTANT LEAKAGE OF EARTH ELECTRICITY OBSERVATION

本文对漏电场进行了系统计算,给出漏电场的空间分布特征;对供电线与测量线间的漏电及其转化进行了理论分析,在此基础上讨论了提高地震台站观测线路抗漏电影响适合地震电法特点的较科学经济的布线原则和方法。荷泽地震台线路改造实例及某些实验结果证明了方法的可行性及其效果。

In this paper, the characteristics of spatial distribution of leakage field were given bycalculating systematically; The leakage and it's transform between supply power wire andsurveying wire were analysed theoretically. On the basis of that a wiring principle andmethod which can improve on resistant leakage of measurement wire were disccused. Theexample to remakel observation wire at Heze seismic station and some experimental resultshave proved feasibility and effectiveness of the method.
