摘要
为了更深入的探讨500k V超高压输电线路电场的结构布局问题,在保证了有限元电磁场的分析软件Ansoft maxwell的科学性和准确性之后,搭建了新的同塔双回输电线路数模。主要探究和分析了相导线相对于地面的距离、分裂导线的构造大小等其他原因对电场产生的影响,还有线路出现了故障或者是进行停电维修时对于电场分布的影响,可以有助于减弱对输电线路周围产生的电场和对电磁环境的更新升级提供了技术和理论的支持,进一步来说,也对停电维修线路提供了一定的参考和借鉴。
In order to discuss the structure layout of electric field of 500kV EHV transmission line more deeply, a new numeri-cal model of double-circuit transmission line on the same tower is built after ensuring the science and accuracy of the finite elementelectromagnetic field analysis software Ansoft maxwell. This paper mainly explores and analyzes the influence of the distance betweenthe phase conductor and the ground, the structure size of the split conductor and other reasons on the electric field, as well as theinfluence on the electric field distribution when the line is out of order or maintenance. It can help to weaken the electric fieldaround the transmission line and provide technical and theoretical support for the upgrading of the electromagnetic environment. Fur-thermore, it can also provide a certain reference for the maintenance of power lines.
