浅析变压器绕组变形及其检测

Analysis of Transformer with Winding Deformation and Its Inspection and Testing

从变压器短路后的分析入手,提出了几种检查和检测变压器绕组变形的方法,综合分析各种方法的优缺点后提出,频率响应分析技术是当前测量变压器绕组变形的最有效工具。并以承德供电公司西地站#1主变发生绕组变形的诊断实例为依据,说明开展频率响应法测量变压器绕组变形的有效性和必要性。

Starting with the analysis of the short - circuited transformer, this paper puts forward a couple of methods of inspecting and testing the transformer with the winding deformation. With the synthetical analysis of the advantages and disadvantages of different methods, the paper points out that the technique of the analysis of frequency responding is nowadays the most effective method to measure the transformer with winding deformation. Based on the diagnosed sample from Xidi No. 1 station＇s major transformer in Chengde Power Supply Company, this paper proves the effectiveness and necessity of carrying out the frequency responding to measure the transformer with winding deformation.
