±1100kV直流输电线路带电作业屏蔽防护研究
Research on Shield Protection for Hot-Line Work on±1100kV DC Transmission Line
摘要
Abstract
As the highest DC transmission voltage level over the world,±1100kV DC transmission line will be built in China soon. Electric field strength in surrounding space of ±1100kV DC line is much stronger than that of±800kV and lower voltage level line. To ensure safety of hot-line work on ±1100kV DC lines, its safety protection should be researched. Firstly, based on proposed screening clothes, test results of hot-line work shield protection on±1100kV DC line were given, including measurements of characteristics of screening clothes, their inside and outside electrical field strengths, flowing through current of hot-line work screening clothes, discharge arc current and audible noise. Then, safety control level of±1100kV DC hot-line work shield protection was analyzed. Finally, based on the test results, precautions for shielding protection in± 1100kV hot-line work were summarized. The results show that it is feasible to hot-line work on± 1100kV DC transmission lines with high quality screening clothes.关键词
