同塔多回路输电线路带电检修技术分析

摘要

文章介绍了同塔多回路输电线路带电检修技术，带点检修的方法；分析了500 kV耐张串绝缘子带电更换可行性。实践表明，带电更换500 kV耐张串绝缘子，能够满足最小安全距离及组合间隙要求，具有很高的可行性。%This paper introduces the technology of live line maintenance of multi circuit transmission lines on the same tower; and analyzed the replacement feasibility of 500 kV tension string insulator. The practice shows that replaced 500 kV tension insulator string can meet the requirements of the minimum safety distance and combination of space, which has a high feasibility.
