摘要
以国内首台1 000 kV特高压变压器现场绕组变形测量试验为例,介绍了采用频率响应法(FRA)和短路阻抗法(SCR)对特高压变压器绕组变形进行综合判断的情况,详细说明了2种方法的特点、现场试验技术和测量结果,有效提高了变压器绕组变形诊断的可靠性和准确性。
Taking the on-site winding deformation measurement of the first domestic 1 000 kV ultra high voltage transformer for example,the frequency response analysis（FRA）and the short circuit reactance（SCR）method are used to synthetically measure the winding deformation of the ultra high voltage transformer.The characteristics,on-site testing techniques and measurement results of both methods are analyzed.Consequently,the reliability and accuracy of transformer winding deformation diagnosis are effectively improved with the synthetic winding deformation measurement.
