摘　　要：近年来,随着上海市政建设的快速发展,配合市政建设的部分线路需进行改造、增加杆塔,传统的线路停电改造施工的停电时间长,将影响系统安全运行。为此,对带电组立220 kV双回路双分裂(630导线)直线塔关键技术进行了论述,经某220 kV同塔双回线路上带电组立直线塔的实践表明,工艺合理、安全,施工装置合适、可靠。Recently,with the fast development of the Shanghai municipal construction,and in order to support the municipal construction,some lines need to be transformed and added with the towers.The outage time of the traditional line outage transformation operation is long,which affects the system safe operation of the system.Therefore,the key technologies of charged grouping 220 kV double-circuits twin bundled（630 conductors） line straight towers were discussed.The practices of the charged grouping the straight towers of one 220 kV double-circuits lines on the same tower demonstrated that the technologies were rational and safe and the operation equipments were suitable and reliable.
