摘要
以220kV永吉和井永同塔双回架空线路实现逆相序排列为例,探讨逆相序排列降低线下工频电场强度的计算原理和理论计算结果,提出具体的实施方案,分析比对线下工频电场强度的实测结果,验证逆相序排列对降低同塔双回架空线路线下工频电场的效果显著,为解决工频电场强度过大探索既经济又实惠的办法。
With the example of reverse sequence in 220 kV Yongji and Jingyong double-circuit overhead transmission line,calculation principle and theoretic result of reverse sequence in decreasing power frequency electric field were discussed and then implementing scheme was put forward.The result proved that reverse sequence is an economic method to solve strong power frequency electric field.
