变压器绕组变形分析及检测

Analysis and Checking of Transformer Winding Distortion

针对近年来因为绕组变形而引发的变压器事故所占比例不断提高的情况。分析了造成变压器绕组变形的一些内外部原因,重点介绍了频率响应法进行绕组变形的检测及分析方法。

Abstract： Aiming at the circs that the ratio of accident caused from winding distortion in transformer accidents is increased continually, the author analyzed some inside and outside reasons to make transformer winding distortion, in this paper, and introduced mainly the frequency-response method used for analyzing and checking winding distortion.
