超高压送电线路下方空间电磁环境的研究

探讨了超高压送电线路下方空间电磁环境问题 ,主要就超高压送电线路辐射工频电磁场进行论述 .利用模拟电荷法计算工频电场 ,离地 2m范围内的合成工频电场 ,其数值和垂直场强差别不大 ,实际测量值与理论计算值基本一致 .工频磁场按静态场计算 ,其大小与地磁场在同一数量级 ,并与实测结果基本相符 .由于我国现在还没有制定工频场强限制的国家标准 ,故本文的数据可供实际工作者参考

On Electromagnetic Environment Below Super-Voltage Lines

We discuss Electromagnetic Environment below Super voltage Lines, mainly focus on power frequency electromagnetic field from Super voltage Lines. Simulation charge method is used to compute the power fiequency electric field, and there is little difference between power frequency electric field of 2 m range from the earth and vertical field. The practical measure valuse are equal to the theoretical values basically. Power frequency magnetic field is computed according to the static field, which value is the same quantitative level as to the earth magnetic field, and be a match for the practical measure result. China lacks of power frequency field strength limit standard. Data in this paper may be provided with reference to practical operators.
