摘要
介绍了国内、外架空线路的导线选型方法和导线载流量的计算原理与方法,在此基础上阐述了决定导线输电能力的主要因素;另外还就国内电力行业设计手册、标准对导线输电能力的计算条件和规定限值进行了对比和分析,给出了江苏电网220 kV,500 kV架空线路常用导线热稳极限载流量的推荐值;最后针对提高江苏电网架空线路的输电能力,提出了几点措施与建议。
This paper introduces both domestic and overseas methods to select conductor of overhead line,and the principles and methods of how to calculate the conductor current capacity.Then it presents the main factors which determine the line capacity.It also contrasts and analyzes the calculating parameters and limits about line transmission capacity on design handbooks and rules of domestic electric power industry,and recommends the current-carrying capacity of common conductors of Jiangsu 220 kV and 500 kV Grid.In the end,it offers some proposals for how to improve the line capacity.
