220kV输电线路跨越河流方案研究

Research on Crossing River Scheme of 220 kV Transmission Line

大跨越是送电线路极其重要时组成部分,跨江方案与工程造价密切相关,跨江点要求选择在地形优越、跨距小以及水文、地质条件较好的地方,并应与一般线路综合考虑,通过技术经济比较确定推荐方案。

Long-span was an extremely important part of transmission lines. The cross-river project was closely related to the project cost. The cross-river point should be selected where the topography was superior, the span was small, and the hydrological and geological conditions were good. The recommended project should be determined through technical and economic comparison with the general line.
