摘要
基于对架空输电线路的导线选型方法与导线载流量计算方法的分析,得出了决定导线输电能力的主要因素,给出了220、500 kV架空输电线路常用导线热稳极限载流量的推荐值,并提出了提高江苏电网架空线路输电能力的措施与建议。
Based on an analysis on conductor selection and the current-carrying capacity calculation of overhead transmission lines,this paper presents the factors which determine the transmission capability,proposes the recommended values of the ultimate thermotolerant current-carrying capacity of common conductors for 220 kV and 500 kV overhead transmission lines and offers some proposals on improving the transmission capabilities of the Jiangsu grid.
