变压器容量选择和最佳负荷范围探讨

A Study of Capacity Selecting and the Optimum Load Range of Transformer

深入地分析了变压器效率特性的特点 ,提出了一种既能保证变压器容量的利用率 ,又能保证在一定负荷范围内高效运行的变压器容量选择方法。文中以 SL7系列变压器为例 ,确定出了 4 0 0～ 16 0 0 k VA容量等级的最佳负荷范围 。

This paper analyzes the transformer efficiency characteristics, taking 10kV grad SL7 series transformer for example and gives the optimum load range of the capacity grad 400 1600kVA. It introduces to the reader a transformer capacity selecting method with great efficiency in operation in certain load range while allowing the best use of transformer capacity.
