摘要
为探讨500 k V超高压输电线路下的电场分布问题,在验证了有限元电磁场分析软件Ansoft maxwell的有效性后,建立了同塔双回输电线路模型。主要分析与研究了相导线对地高度、分裂导线结构尺寸等因素对电场特性的影响,以及线路发生故障或停电检修时电场分布的变化规律,这为降低输电线路周围电场和对电磁环境的优化提供理论依据和方法,同时对停电检修线路注意事项提供一定的参考。
In order to investigate the electric field distribution problems under 500 k V EHV transmission lines and establish the same tower double circuit transmission line model after verifying the effectiveness of the finite element electromagnetic field analysis software Ansoft Maxwell,this paper mainly analyzes the influence of the phase conductors to ground height,split wire structure size and other factors on the characteristics of the electric field,and the variation of the line electric field distribution when a fault occurs or outage maintenance,which is to provide a theoretical basis and methods for reducing the transmission lines around the farm and optimizing the electromagnetic environment. At the same time,it provides a reference for outage maintenance lines.
