| 中文摘要:为估算出超高压输电线路下方的电场分布情况，采用等效电荷法的计算模型，并简要介绍有无架空地线两者之间的区别。通过MATLAB仿真软件对某一实际500kV输电线路的电场进行仿真，分析其周围电场特性。针对输电线路是否投运，提出几种不同的降低输电线路周围电场强度的方法，可为降低500kV输电线路工频电场的实施措施提供参考。 |

| Abstract:Calculation model called equivalent electric charge is used to estimate the distribution of electric field below Ehv transmission lines, besides, difference between with aerial landlines or not are also briefly introduced. Through the simulation of MATLAB software for a practical 500kV transmission line, its surrounding electric field characteristic is analyzed in the paper. Aiming at ehv transmission lines whether be into operation or not, it puts forward several different ways to reduce electric intensity, and it can be provided reference for reducing power frequency electric field of 500kV transmission line. |
