摘　　要：通过对城区电网和农村电网负荷特点的分析,将城区电网划分为15类、农村电网划分为8类应用场景,结合配变效率、效益的含义及关键指标划分,通过对配变运行指标的理论分析,找出指标间的逻辑关系,给出不同应用场景下配变最大经济负载率和单位配变容量年供电量推荐值。Through the analysis of the load characteristics of urban and rural power grids,the urban power grid is divided into 15 categories and the rural power grid is divided into 8 application scenarios.Combined with the meaning of distribution transformer efficiency and benefit and the division of key indicators,the logical relationship between indicators is found out through the theoretical analysis of distribution transformer operation indicators,and the recommended values of maximum economic load rate and annual power supply per unit distribution transformer capacity under different application scenarios are given.

关 键 词：配变效率 经济负载率 年供电量
