摘要

对高邮台地电NS向ρs的观测精度在2002 07 24雷雨后出现降低的现象进行了分析排查,发现是一交流接触器在遭雷击时烧坏,导致交流电三相中的一相对地漏电,与变压器中的零线形成回路所致。从而排除了配电房漏电的干扰,保证了观测资料的质量。
Comprehensive analyses and examinations are made of the reason for the reduction of the accuracy of the ρs observations on NS component at the Gaoyou Seismic Station after a thunder shower on July 24,2002. It is found that an a.c. contactor was burned down, leading to the leakage of electricity of one of the three phases of the alternate current to the earth and a loop was formed with the zero line in the transformer. Then, the disturbance was eliminated and the quality of observational data is ensured.
