摘　　要：对目前应用较为广泛的几种增容导线进行了介绍,以上海电网中几条实际输送功率较大的220 kV线路为例,探讨了导线增容技术在上海电网中的应用情况.在导线截面相同的情况下,碳纤维芯软铝导线的增容效果与其他类型增容导线相当,甚至更优,但其水平荷载和垂直荷载均明显小于其他类型的增容导线,弧垂特性优势更加明显.其他类型增容导线无论截面大小其弧垂均大于原常规导线,部分碳纤维芯软铝导线的弧垂较原常规导线有所减小.Several types of augmented capacity conductor which are widely used are introduced.Based on the research of several 220 kV lines with large transmission power in Shanghai grid,the application of augmented capacity conductor to overhead power transmission lines in Shanghai is studied.In case of same section,the soft aluminum conductor carbon fiber reinforced (SACCFR) brings about a striking effect in capacity augmentation,even superior to other types of augmented capacity conductors.Its horizontal load and vertical load are smaller,and its sag is also evidently smaller than that of other types of conductors.The sag of this ACCC is smaller than that of general types of conductor,but as for other types of augmented capacity conductor,the sags are bigger no matter how big their sections are.
