摘要 频率响应分析法诊断变压器绕组变形建立在比较曲线图谱的基础上,频响曲线的变化所对应的绕组变形种类需要结合具体案例进行细化总结。本文应用频率响应分析法对某110kV主变事故前后的绕组频率响应曲线进行比较,结合相关系数,对该主变绕组变形情况进行了分析判断,结合吊罩检查情况,对该主变绕组变形形态的频响曲线分频进行了综合分析与总结。

Abstract:The diagnosis of transformer winding deformation using frequency response analysis is based on the comparison of curves. The variation of frequency response curves corresponds to the types of winding deformation needs to refine and sum up, combed with the concrete case. In this paper, the winding deformation frequency-response curve of an 110kV power transformer is analyzed based on frequency response analysis. Combined with the correlation coefficient, the situation of main transformer winding deformation is analyzed and judged. With disassembling inspection, the frequency division of the frequency response curve are comprehensive analyzed and summarized.
