摘　　要：通过对不同电压等级的主变运行情况的统计分析发现,变压器绕组电容量的变化大小与绕组的变形程度相关。提出了基于变压器绕组电容变化量来初步判断变压器绕组是否变形的简便方法。According to the statistics of the operating results of some different main transformers,it is found that the rate-of-change of capacitance in transformer windings is related to the wind-ing deformation.The simple method to judge deformation of transformer windings according to ca-pacitance of transformer windings is presented.
