建设资源节约型输电线路时所使用的导线

本文针对我国"十一五"期间为建设资源节约型输电线路的要求,对现有导线和近年来国内外出现的各种新型导线的性能,应用范围等作详细的评说,并提出对于主干线路用导线,应着重考虑节能、节约线路用地,在N-1时的精况下能安全运行;对于老旧线路改造用导线,应着重考虑线路改造后扩容时的弧垂特性。文中对我国输电线路用导线的生产、研制概况、规模给予介绍,提出研制新型导线的原则,指出创新是最重要的方法。

Conductors for Construction of Resource-Conserving Type of Transmission Lines

In terms of the requirement for construction of resource-conserving type of transmission lines during the 11~(th) Five Year Plan,the author of this paper made a detailed comment on the existing conductors and those newly developed conductors at home and abroad in recent years for their properties and applications and suggested that for the conductors for main lines,the focus should be on energy-saving and saving the land for power lines and the possibility of safe operation under the N-1 condition;for the conductors for renovation of old power lines,the focus should be on the sag characteristics with increased capacity due to renovation.The author presented the production,R & D and scale of the conductors for transmission lines in China and the principle for R & D of new conductors,indicating innovation is of most importance.
