Abstract During selection of distribution transformer，the high efficiency, energy-saving and factors in economy operation etc. shall be taken into account. Based on the current policies for power supplying, optimization of transformer capability in view of energy-saving and discount rate of total cost is analyzed，and a dynamic and quantitative selection way is proposed.  

Key words　Transformer　Energy-saving Power supplying condition　Total cost

摘　要　配电变压器的选择，要考虑高效节能，同时考虑经济运行等因素。通过工程实例，在目前的供电政策下，从节能、综合费用折现值等角度分析变压器的容量优化，提出一种动态量化的选择解决方式。
