±660kV直流同塔双回输电线路带电作业试验研究
Experimental Research of Live Working on ±660 kV Double Circuit DC Transmission Line on the Same Tower
摘要
Abstract
In order to determine the technical requirements of the safety distance,the complex gap,the working mode and the safety protection etc.for live working on ± 660 kV double circuit DC transmission line on the same tower,based on the practice ±660 kV transmission line project,the maximum operating over-voltage level for live working on the line was obtain through simulation calculation and simulation experiments.Based on these,the minimum approach distance on ± 660 kV double circuit AC transmission line on the same tower at different altitudes were determined through the 1：1 ratio scale simulated tower,including the altitudes of 500,1000,1500 and 2000 m.The minimum complex gap of entering equal potential has got at the same time.Otherwise the electric field intensity on live working human-body surface and the energy traverse human-body when potential is shifting are simulated and calculated,and the main parameter requirement of the screen clothes was presented.The results of this experimental investigation provide technical support and reference for live working on 660 kV double circuit DC transmission line on the same tower.关键词
