摘要
若想将变压器并联使用 ,必须知道变压器的组别。介绍如何用电压法测定三相变压器联接组别及鉴定组别的计算公式。从公式可知 ,变压器联接组别的向量变化是有一定规律的。
The transformer term must be distinguished before parallel using.Introduces how to use the ways of voltage to determine three terms transformer the formulas of the differences of joining generators and the differences of appraising generators.We know the atransformation has fixed law,foom formulas.
