摘要

在目前用电负荷持续增加的趋势下,长距离跨区域输电已经成为较重要的输电模式,为了提高输电线路的经济性、稳定性、可靠性与环保性,需要提高节能导线的使用频率.如果现有的高压输电线路全部替换成节能导线将会节约45亿kW·h左右的电能,相当于150万t的标准煤.文章以某输电工程为例,基于实际条件和建设要求分析了导线选型的设计方案,提出了1种常规导线和3种新型节能导线,3种节能导线分别是钢芯高导电率硬铝绞线、铝合金芯铝绞线和中强度全铝合金绞线,并从其载流量、线路损耗、机械特性、经济性等指标对导线进行对比研究,以期为类似的输电项目提供参考.

Abstract

Taking a certain transmission project as an example,this article analyzes the design scheme of wire selection based on actual conditions and construction requirements.One conventional wire and three new energy-saving wires are proposed,which are steel core high conductivity hard aluminum stranded wire,aluminum alloy core aluminum stranded wire,and medium strength all aluminum alloy stranded wire.The wires are compared and studied from their current carrying capacity,line loss,mechanical characteristics,economy and other indicators,in order to provide effective reference for similar transmission projects.
