摘要

随着"西电东送"工程的开展以及紧凑型输电技术的应用

高海拔紧凑型线路在中国不断出现。为了保证这些线路带电作业能安全进行

需要对带电作业过程中的安全距离和组合间隙进行研究。笔者针对500 kV高海拔紧凑型输电线路带电作业进行了一系列试验研究

对海拔为2 000

000 m的紧凑型线路带电作业安全距离与组合间隙进行了危险率计算

计算结果表明

德宏高海拔紧凑性输电线路直线塔边相、中相和下相带电作业安全距离和组合间隙满足安全性要求

研究结果可为在500 kV紧凑型高海拔输电线路杆塔设计与带电作业开展提供技术参考。

Abstract

With the implement of ‘power transmission from west to east’project and the application of compact transmission technology

many compact transmission lines have been applied in China

even in high altitude areas of China.In order to carry out living work on these lines

it is necessary to study the approach distance and complex gap during living work.A serial experiments have been carried out to reseaerch the living work of 500 kV compact transmission lines in high altitude area.The risk rate of approach distance and complex gap of living work on compact transmission line at altitude between 2 000 m and 3 000 m are calculated according test results.The results of calculation show that approach distance and complex gap of Dehong compact highaltitude 500 kV transmission line satisfy the safety requirement of living work.Research results provide references for the design of pole and tower and impeletion of living work of 500 kV compact transmission lines in high altitude area.
