Abstract:

Windings’ deformation is one of the most frequent faults for the power transformer. Based on the vibration frequency response analysis, this paper proposes a correlation coefficient of vibration frequency response curve in order to more effectively detect the windings deformation. In the experiments, the vibration frequency response method is used to detect the states of largescale power transformers windings which are manmade fault. The results analysis shows that this correlation coefficient is sensitive to the windings deformation.

Key words: vibration and wave, transformer, winding, frequency response, correlation coefficient

摘要：

为了更加有效地识别绕组的变形故障，在基于机械振动频响法对变压器绕组进行检测的基础上，提出了标示绕组形变程度的振动频响曲线相关系数。通过对大型变压器的绕组进行人为故障设定，利用机械振动频响法对故障绕组进行检测，试验证明该振动频响曲线相关系数对判断变压器绕组变形具有较高的灵敏度。
