摘要
在对750 kV变电构架进行选型时,以4孔出线门形构架为例,采用目前国内外500 kV及以上电压等级变电站常用的几种构架结构型式,运用空间分析计算程序进行整体分析计算,并进行技术经济分析比较。同时,对构架柱平面、立面、腹杆型式以及柱根开的选型进行方案论证,提出较为合理的出线构架梁、柱结构型式,为其他类似工程提供参考。
When deciding the 750 kV substation truss structure, using 4--oulet portal frame as an example, several truss structures commonly used in domestic and foreign 500 kV and above substations are selected. Spatial analysis program is used to perform overall analysis calculation and technical and economical analysis comparisons are also conducted. In the mean time, it demonstrates selection of column plane and section, web member and column root width selections, and brings forward rational selections of beam and column structure of the truss to provide references for similar projects.
