新型500kV线路180°转角终端塔设计研究OA
Research on the New 180° Angle Terminal Tower for 500 kV Transmission Line
目前,一般输电线路的耐张塔的转角度数设计范围仅为0°～90°之间.若要实现更大角度的转向,则只能利用多基铁塔来实现.由于架设地貌、环境保护、土地规划等特殊情况下,线路转角可能大于90°,甚至达到180°.本文依托某水电站重建工程,改进了相导线的布置与跳线的连接,优化了铁塔结构,设计了一种全新的500 kV线路180°转角终端塔,满足大角度出线的需求,减少土地资源占用,实现了保护自然环境与提高经济效益的双赢.
At present,the line angle of tension tower is only between 0° and 90° for normal transmission lines.If larger angle is necessary,it can only be achieved by using more than one tension towers.Due to special circumstances such as geomorphology for installation,environmental protection,land planning and so on,the line angle may be larger than 90° or even up to 180°.Based on the reconstruction project of a hydropower station,this paper improved the phase conductor arrangement and jumpers connection,optimized the tower structure.Designed a new 180° angle terminal tower for 500kV transmission lines,which can meet the demand of large angle outlet,reduce the occupation of land resources,and realize protecting environment and improving economic benefits at the same time.
