基于有限元方法500kV交流输电线路表面电场强度的研究
摘要
本文基于有限元方法详细讨论了500 kV交流输电线路导线表面电场的分布规律
并定量分析了线路参数及导线表面特性对导线表面最大电场强度的影响。结果表明
线路采用多分裂、大截面、倒三角布置方式
可以降低导线表面电场强度;不光滑导线将导致导线表面电场增大。
Abstract
In the paper
the surface electric field distribution of 500 kV transmission line are discussed in detail based on finite element method
and the impact of line parameters and surface characteristics on maximum electric field of transmission line are also analyzed quantitatively.The results verify that the more sub-conductor
large conductor section and inverse triangle configuration design can reduce the surface electric field
while the non-smooth surface can cause the surface electric field enhancement.
