摘要
目前,我国已(在)建的±800kV特高压直流输电线路的极间距离均按不小于22m设计。综合考虑电磁环境、合成绝缘子串长、空气间隙、V型绝缘子串夹角等因素,探讨极间距进一步缩小的可能性,并对其经济效益进行分析,为后续特高压直流输电线路的设计提供参考。
At present,it is required that the polarity distance of ±800 kV UHV DC transmission lines constructed or constructing is not less than 22 m in our country.In this paper,the possibility of decreasing the polarity distance is discussed by considering electromagnetic environment,length of the composite insulator string,air gap,angle of the V style insulator string and so on.In addition,the economic benefits are analyzed.The results obtained provide references for the design of future UHVDC transmission line.
