| 摘 要： | 为了研究同塔双回紧凑型输电线路周围的电场分布,将每个子导线的表面进行剖分,以各个节点的电荷面密度作为变量,根据电磁场理论建立线性方程组来求解各个节点的电荷面密度,然后计算输电线路周围电位、电场强度的分布。同时,对目前工程中使用的每相工作电容进行分析,指出这个概念在理论上的缺陷,提出用部分电容作为输电线路的参数,并提出了计算部分电容的数值方法。

| Abstract: | In order to study the electric field around 550 kV double circuit compact overhead transmission line on same tower,the surface of every bundle conductor was divided into many arc segments,surface charges density of every node were set be variable,and linear interpolation is used to express the charges density of every arc segment. According to the electromagnetic theory,linear equations were set up to calculate the surface charges density of every bundle conductor,then the distribution of potential and elec... |
