110kV同塔四回输电线路工频电场的研究

Research on the Power Frequency Electric Field of 110 kV Four Circuits on the Same Tower

根据镜像法和叠加原理,对110kV同塔四回路输电线路的工频电场进行计算研究.分析输电线在不同的相序排列,导线水平间隔距离,杆塔高度和导线排布等情况下在地面附近的电场分布情况.提出减少线路周围工频电场的措施,为电网建设提供理论参考.

Calculation of the power frequency electric field strength of the 110 kV four circuits transmission line is made according to the image method and superposition theorems.There are many parameters affecting the distribution of the electric field of the overhead transmission lines,such as the phase sequence arrangement,the wire spacing,the height of the tower,and the arrangements of conductor.The results show that thefactors investigated have different levels of effects on the electric field distribution,and measures to reduce the electric field were proposed.
