摘　　要：黄草营330 k V变电站是进出线柱和母线柱均为A型柱的构架,在其原有结构基础上,进行优化设计。将进出线构架柱采用钢管混凝土单杆柱代替常规的A型柱,中间构架柱采用钢管混凝土A型柱,进出线构架通过母线构架梁及进出线构架梁与中间构架结合在一起,形成整体受力体系。重点论述其结构方案、荷载组合、杆件选择、计算结果分析等,并与常规330 k V构架的经济性进行比较,提出较为合适的330 k V全联合钢管混凝土构架结构形式。The 330 kV substation of Huangcaoying＇s inlet-outlet and busbar line towers were A-shaped columns. On the basis of the original structure, an optimal design was conducted. The structure type of the entirely combined gantry was that the ingoing-outgoing overhead line towers used single CFT pipe instead of the A-shaped columns, the middle towers used the CFT A-shaped columns, and the ingoing-outgoing overhead line towers were connected with the middle towers by the busbar. The structure scheme, the load characteristics, the selection of members, the calculation results were emphasized to discuss in this paper. The more suitable structure type for the entirely combined gantries was put forward by comparing with the conventional 330 kV gantries in consideration of economy.
