摘要
为配合三沪±500 kV直流输电线路的同塔双回改造工程,根据带电作业技术特点,结合该线路塔型、导线布置以及作业人员在塔上的作业位置等实际情况,开展了1:1模型的带电作业的试验研究。根据研究结果提出了±500 kV同塔双回直流线路带电作业典型工况下的最小安全距离和最小组合间隙,为线路塔头间隙尺寸设计和线路带电作业工作开展提供技术依据。
In order to cooperate with the double circuit modification work of San-Hu ±500 kV DC transmission line,the live working test is studied.According to the characteristics of live working,the test is processed based on practical situation of tower model,transmission line layout,and the operating personnel＇s working position on tower.The minimal safety distance and minimal compounding gap of typical working condition in ±500 kV double circuit DC transmission line are put forward,which provides technique basis to the design of tower head＇s gap size and the practice of live working.
