摘要
随着越来越多的电网高压线路的投入运行,对地磁观测造成了较大范围的干扰,这种干扰需要通过预处理进行解决。该文根据地震地磁观测的主要任务和基本原理,结合蒙城地震台的观测数据,从台站提供的地磁干扰资料着手,研究由于直流线路影响地磁观测数据的特点。通过对安徽蒙城地震台的地磁观测(GM4磁通门磁力仪)的高压直流输电的干扰的动态特征进行分析,同时,介绍了对高压直流干扰的预处理的一般方法。
As more and more put into operation of high--voltage lines, causing interference to the geomagnetic wide range of such interference needs to be resolved through preprocessing. Based on the main tasks and basic principles of geomagnetic observation, combined with observations of Mengcheng Seismic Station, geomagnetic disturbances from the station to provide information to proceed, because the DC line impact study geomagnetic data features.Dynamic characteristics through Anhui Mengcheng Seismic Station geomagnetic observation(GM4 fluxgate) HVDC interference analyzed simultaneously describes the general method for the pretreatment of HVDC interference.
