| 摘 要： | 为研究不同电压等级线路同塔多回架设时线下工频电场分布,对运行的330 kV、110 kV同塔四回线路及分开架设时线下工频电场进行了实测,利用ANSYS有限元分析软件计算了同塔四回不同排列方式的线下工频电场。结果表明:330 kV、110 kV同塔四回架设较分开架设时线下工频电场分布得到明显改善;330kV、110 kV线路分别采用逆相序排列,且同侧上层330 kV与下层110 kV线路也为逆相序时,线下工频电场分布改善效果最佳。

| Abstract: | To study the power frequency electric field distribution under four-circuit lines on the same tower with different voltage degrees,this paper measured the distribution of power frequency electric field under the operating four-circuit lines on one tower with the two voltage degrees: 330 kV and 110 kV,and measured that under the separated 330 kV and 110 kV double-circuit lines respectively.ANSYS finite element analysis software was applied to calculate the field distribution under four-circuit lines on the s... |
