摘　　要：本文从电力变压器实际运行情况出发，分析了功率损耗最小原则的片面性，提出按电能损耗最小原则来选择变压器容量。本文对变压器运行节能也进行了系统分析。另外，按电能损耗最小原则论述了备用变压器投入或切除的条件。According to the operations of power transformers,the error og the smallest power loss principle is discussed in this paper.The selecting method of the transrormer capacity based on the smallest energy loss prindiple is introduced.The operating ways for saving energy are analysed systematically. The conditions under which the reserve transformer is turned on or off are discussed.
