摘要
针对近年来国内采用同塔多回架空输电线路中存在的问题,给出了同塔多回高压架空输电线路在设计、施工、制造和建设运行等方面采用的主要技术参数,并进行了经济性分析。分析结果表明:在部分线路路径选择特别困难或通道投资特别高的地区,同塔多回架空输电线路具有比较明显的优越性,可在工程中有选择性地采用同塔多回架空输电线路的型式。给出的设计原则可为将来健全输电线路设计规程提供参考。
In view of the existing problems of multi-loop overhead transmission lines in China, the main technical parameters of the multi-loop overhead transmission lines adopted in design, construction, manufacturing and operation phases are described and corresponding economic analysis is made. The analysis shows that the multi-loop overhead transmission lines have obvious advantages over single-loop overhead transmission lines in the regions where route conditions are very poor or cost for rout path is very high. Therefore it is advisable to selectively adopt the multi-loop overhead transmission lines in some places. The design principles proposed in this paper can be used as a reference for revision of the existing design codes of transmission lines.
