摘要
随着宁夏至山东电网高压线路的投入运行,对河南浚县地震台的地磁观测(FHD-2质子矢量磁力仪)造成了一定的干扰。分析了高压直流输电干扰的动态特征,介绍了干扰的预处理方法。
The geomagnetic observation( FHD-2) in Junxian seismic station is interfered by the Grid highvoltage lines from Ningxia to Shandong.The dynamic characteristics of high-voltage transmission interference are analyzed,and the methods of interference clearing are introduced in the paper.
