摘　　要：针对高寒地区特殊的气象条件,研究了110kV城网中提高导线温度的可行性及提高导线温度后主变的过载能力,并给出了计算依据和结果。线路试运行结果表明,将导线允许温度从70℃提高到80℃时,除部分配套金具不能满足要求外,主变及其他均能安全运行。This paper studies feasibility and major transformer＇s over loading ability of improving temperature of conducting wire in 110 kV urban network in a condition of special plateau environment, then provides calculation basis and results. The test run result of transmission line shows that if we increase permitted temperature of conducting wire from 70℃ to 80℃,the major transformer and other devices can be safe in operation except that a part of auxiliary accessories can not meet the need.

关 键 词：高寒地区 导线容许温度 主变 过载能力 输送容量
