330 kV输电线路采用酒杯塔合理性分析

The Rationality Analysis of Using Cup Type Tower in the 330 kV Transmission Line

对单回架空输电线路而言,国内外广泛采用的塔型主要有酒杯塔和猫头塔,两种塔型各有优缺点。然而在330 kV输电线路工程中,单回路直线塔很少使用酒杯塔,《国家电网公司输变电工程通用设计(330 kV模块)》中单回路直线塔全部为猫头塔。本文以甘肃洛大-绿源-巩昌330 kV线路工程为背景,对甘肃南部山区单回架空输电线路直线塔选用酒杯塔的合理性进行分析。建议《通用设计(330 kV模块)》中单回路直线塔增加酒杯塔。

Cup type tower and cat head type tower are mainly used in the single loop overhead transmission line at home and abroad,both of which as advantages and disadvantages.However,in the 330 kV transmission line project,cup type tower was rarely used as single loop tower.Cat head type tower was used as the only single loop linear tower by"General design of the State Grid Corp transmission project(330 kV module)".The rationality of of choosing cup type tower as single loop linear tower for transmission line in southern mountainous area of Gansu will be analyzed in this paper,which takes Luoda-Luyuan-Gongchang 330 kV transmission line project as the background.Increasing cup type tower in"General design of the State Grid Corp transmission project(330 kV module)"was suggested in this paper.
