摘　　要：为解决西北高海拔地区日益增长的输电容量与走廊紧张的矛盾,在750 kV同塔双回紧凑型关键技术研究的基础上,通过理论分析、试品研制及悬挂力学试验,在线路电磁暂态、导线排列、悬挂方式、铁塔结构及技术经济等方面进行了深入分析,研究提出了提高输送容量节约走廊的双回导线同窗布置及塔头型式,并给出了直线塔设计方案、线路适用条件,结合工程计算分析了潜在的经济效益。To resolve the contradiction between the rising power flow and the narrow corridor, based on the key technology research of 750 kV double-circuit in single tower window compact line, through the theoretical analysis, making sample and mechanics test, this paper researches the electric-magnetic transient, lines arrangement, hanging, tower construction and technical economy, and gives the idea of double-circuit in single tower window to improve the transmission line power and induce the corridor. At last, this paper put forwards the design of the single tower window compact line, the surroundings to be used, and the potential economic benefit by the project sample.
