摘　　要：通过对住宅负荷不同季节的数据测量,给出了目前配电变压器负荷率的一般情况,对变压器的最佳负荷率进行推导,通过给定的负荷曲线找到实际情况下最佳的变压器容量,并对变压器损耗计算过程中需要的年最大负荷利用小时数进行了研究,分析结果可以为设计过程中变压器容量选择提供参考。Through the measurement of residential load data in different seasons, the general situation of load rate of distribution transformer at present was given. And then the optimum load rate of transformer was discussed, the best transformer capacity under actual conditions by a given load curve was determined. Finally the loss hour was studied, which was needed in tile process of transtonner loss calculation. The data and analysis results could provide a reference for transformer capacity selection in the design process.
