摘　　要：本文中作者分析了一台型式为SFZ11-31500/110变压器高、低压绕组同时变形的故障案例。采用短路阻抗法和频率响应法诊断了其绕组变形情况,查明了故障具体部位及损坏程度。A fault case in which the high and low voltage windings of the SFZ11-31500/110 transformer are deformed by the authors in this article. The short-circuit impedance method and frequency response method are used to diagnose the winding deformation,and to find out the specific fault location and damage degree.
