摘　　要：介绍了一起110k V变压器经受短路冲击后的故障情况。在油色谱、直流电阻和变比数据正常的情况下,运用频率响应法、电容量测试及低电压短路阻抗法对绕组变形情况进行了判断,给出了解决方法。The fault after short circuit impulse of 110kV transformer is introduced. Under normal data of oil chromatographic analysis, DC resistance and ratio, the winding de- formation is judged with the frequency response, capacity test and LV short circuit impedance method. The solution is presented.
