摘　　要：采用频率响应分析法检测运行中的变压器绕组变形是一种较灵敏的方法,近年来在全国得到广泛的应用,效果非常显著,但是,在判断分析事故方面仍缺乏相应的国家标准指导。为避免误判断造成的巨大损失,介绍了几种判断变压器绕组变形的辅助分析方法,补充了频率响应分析法在判断绕组变形上的不足。The frequency response analysis （FRA） technology has been widely adopted to detect winding deformation of operating transformers and good effects have been achieved. However, there is still lack of national standard guidance in analysis and judgment of faults. To avoid heavy losses caused by misjudgment, this paper introduces several auxiliary test methods to judge transformer winding deformation, so as to counteract the weakness of FRA in the judgment of winding deformation.
