| 摘 要： | 介绍了应用频率响应分析法检测变压器绕组变形的两个实例.指出在检测中通过对前后频谱曲线的分析,能准确有效地发现变压器内部电气及机械事故隐患,对于变压器及电网的安全运行有着重要意义.但频率响应分析法不一定能够有效反映出变压器绕组变性发生单一扭动变形这类故障,绕组变形的诊断仍需使用多种试验手段综合分析和判断.

| Abstract: | This paper presents two fault-diagnosis examples for the winding deformation of electric power transformer using frequency responae analysis. It is pointed out that the hidden electrical and mechanical troubles in power transformers can be effectively detected by comparing the frequency response curves before and after the detection. This technique plays a significant role in the secure operation of the transformers and power network. However, frequency response analysis can not detect some faults such as simplex twist deformation. More experimentation and judgment approaches are needed in the diagnosis of power transformer winding deformation. |
