摘　　要：采用列表分析法对SF7、SF8、SFZ9、SFZ10等4个系列的110 k V双绕组变压器的耗能参数、在最小损耗运行方式下的最大效率和最佳负荷率及不同负荷率时的效率和损耗进行了分析比较,得出4个系列110 k V变压器的最大效率、最佳负荷率、经济运行区、经济容量的确定方法思路,并对新建或扩建的变电站110 k V双绕组变压器的选型提出了建议。In the paper, the determination methods of maximum efficiency, optimum load rate, economic operation interval and economic volume of 110kV two-winding transformers of four series i.e. SF7, SFS, SFZ9 and SFZ10 are explored by comparing and analyzing the energy loss parameters, the maximum efficiency and the optimum load rate under minimum loss operation mode as well as the efficiency and loss under different load rates through list analysis method. Besides, some suggestions are given to the type selection of 110kV two-winding transformer for newly-built or extended substation.
