日前,国家电网公司科技项目“750kV输电线路电晕损耗的实测研究”通过了专家组验收。该项目针对750kV交流输电线路的电晕损失问题,在对不同海拔和气候条件下进行大量实际测量和理论分析的基础上,提出了750kV六分裂导线电晕损失海拔修正新方法,可直接指导高海拔下750kV输电线路导线结构的设计,研究成果达到国际领先水平。 Recently, the State Grid Corporation of Science and Technology Project “750kV transmission line corona loss measurement research ” passed the expert group acceptance. Aiming at the corona loss problem of 750kV AC transmission line, this project proposed a new method of altitude correction for corona loss of 750kV six-split conductor based on a large number of actual measurements and theoretical analyzes under different altitude and climatic conditions, The design of conductor structure of 750kV power transmission line under the altitude has reached the leading level in the world.
