摘要
针对发达地区难以开辟新的线路走廊问题,为能满足老旧线路杆塔的使用条件,需采用各种耐热导线对老旧线路进行改造,从电气特性、机械特性以及经济性等方面对比研究了钢芯铝绞线、碳纤维复合芯导线,殷钢耐热铝合金导线和间隙型导线等5种导线的优缺点,提出各种导线在增容改造工程中的使用方案,增容改造线路一般可以考虑殷钢导线和间隙型导线。
For developed areas,it is difficult to develop new line corridors.In order to meet the service conditions of old line poles and towers,a variety of heat-resisting wires are needed to transform the old lines.The advantages and disadvantages of five kinds of wires,such as steel core aluminum stranded wire,carbon fiber composite core wire,invar heat-resisting aluminum alloy wire and clearance type wire,are compared and studied from the aspects of electrical characteristics,mechanical characteristics and economy.The application schemes of various wires in capacity expansion and reconstruction projects are put forward.Generally,invar wire and clearance type wire can be considered.
