摘要
基于动态增容理论,和在现有输电走廊的基础上提高输送容量的理念,建立输电线路暂态运行方程,给出了导线允许温度与弧垂的关系式,对220 k V输电线路热弧垂特性进行了分析。
Based on the dynamic capacity-increase technology,and the idea to increase the transmission capacity on the foundation of existing power transmission corridors,the thermal sag characteristics are analyzed for 220 k V overhead transmission lines. The transient operation equation of the transmission lines is established. The relationship between the allowed temperature and the sag is then given.
