摘　　要：变压器损耗在电力系统损耗中占有相当比例,严重时甚至超过系统损耗的1/2,导致大量电能浪费。针对现状,提出了调整变压器运行方式的方案来减少损耗。根据变压器的损耗特性,分析了变压器负载率、容量等因素对变压器损耗大小的影响,提出了变压器经济容量的选择方法。Loss in the transformers accounts for a considerable proportion of the total loss in the power system .The pro-portion may be even higher than 50 percent in the worst case .In this paper , a recommendation is given to change the operation mode of transformers to reduce the transformer loss .Based on the characteristics of transformer loss , effects of several parameters such as the load rate and capacity of the transformer on the transformer loss are analyzed .Then , a se-lection method is proposed on the economic capacity of the transformer .

关 键 词：变压器 经济运行 最佳负载率 变压器容量
