摘　　要：利用全国地磁台站地磁秒数据干扰资料,统计了27条高压直流输电对地磁观测H、D分量造成的干扰情况,研究高压直流输电对地磁观测H、D分量的影响特点,根据统计结果得到了地磁观测H、D分量受高压直流输电影响的多种干扰形态,并对各类形态产生的原因进行了分析,对H、D分量受高压直流干扰形态有了更清晰的认识。Based on the geomagnetic second data of national geomagnetic stations,the interference of 27 high voltage direct current(HVDC)lines on H and D components of geomagnetic observation are counted,and the influence of HVDC transmission on H and D components of geomagnetic observation are studied.According to the statistical results,various interference forms of H and D components of geomagnetic observation affected by HVDC transmission are obtained,and the causes of these forms are analyzed,so that the interference forms of H and D components by HVDC are more clearly understood.
