| 摘 要： | 间隙型增容导线主要是以钢芯和(超)耐热合金层之间有一定的间隙为特色,利用(超)耐热铝合金和“间隙结构”结合实现了低弧垂和增容特性.在输电线路进行增容改造时只要简单地更换导线,就能实现1.6～2.0倍的输送容量而不增加弧垂.通过分析间隙型增容导线与钢芯铝绞线的弧垂特性以及线路载流量与温度弧垂特性的关系,提出了间隙型增容导...

| Abstract: | The up-rating conductor consists of steel and（supper） resistant aluminum alloy,which a certain gap between layers is ＂loose＂.Low-sag and transmission capacity are achieved by（super） resistant aluminum alloy and gap structure.The transmission capacity can achieve 1.6~2.0 times without increasing the sag by replacing the conductor when the transmission line is refurbished.The sag characteristics,transmission capacity and the relationship of temperature and sag characteristics are analyzed between the up-rating conductor and ACSR,and the basic principles of replacing up-rating conductor are suggested,which is guiding significance to transmission line of refurbishment. |
