摘　　要：介绍了一起220 kV电流互感器引流板变形缺陷分析及处理过程。通过对电流互感器引流板受力分析、仿真模拟及试验检测,认为引流板未达到设计厚度,不能承受现场实际应力是发生变形的主要原因。通过对这起缺陷的分析研究,对今后类似缺陷的分析提供借鉴与参考。This paper introduces a defect analysis and handling process of the conductive plate bending deformation of a 220 kV current transformer. Through the stress analysis, simulation and test on the conductive plate of current transformer, it is considered that the strength of the conductive plate does not meet the design thickness and is unable to bear the actual stress. The analysis of the defects will provide reference for future similar defect analysis of current transformer.
