摘要
目前,我国已有的500kV紧凑型线路耐张塔主要参照国外经验设计,在山区应用时,跳线对地间隙的矛盾突出,常有树木砍伐及跳线开发等现象。本文综合考虑其塔型结构、跳线串型式、空气间隙等因素,探讨500kV紧凑型耐张塔塔型优化的可能性,并对其经济效益和社会效益进行分析,为后续500kV紧凑型线路的耐张塔设计提供参考。
At present in our country, The tension tower of 500kV compact transmission line is mostly designed according to foreign experiece,the air gap between jumper and ground is always inadequate when the 500kV compact transmission line is used in the mountain, which causes tree felling and earthwork, this essay considers compositely the tower structure, junper isulator string and air gap of the tension tower and so on, disscusses the the possibility of optimum research, and research the economic benefits and social effects, provides reference for the design of 500kV Compact Transmission Line in the later.
