摘要
考虑到大地的非均匀性,为准确计算高压输电线路避雷线中的电能损耗,建立了土壤水平分层模型,以两层土壤为例,基于麦克斯韦方程组,推导出了电磁场等效作用宽度的计算公式,提出了考虑土壤水平分层结构时避雷线各阻抗参数的计算方法。
In view of the heterogeneity for the earth,a multi-layer horizontal soil model is built in order to calculate the power loss accurately in lightning-shield line for high voltage transmission.Based on Maxwell's equations,the formulas of equivalent width for the electromagnetic field are deduced,this article also puts forward a way of the calculation for impedance in the lightning-shield line when considering the two-layer horizontal soil.
