摘要
本文中作者分析了一台变压器的高压绕组损坏故障案例。通过油色谱分析、短路阻抗试验、直流电阻测量等判明故障类型,解体检查验证分析结论和查明故障部位,并根据故障原因,提出了改进措施。
The winding failure case of transformer is analyzed by the authors in this pa-per.The fault type is determined by oil chromatography analysis,short circuit impedance test and DC resistance measurement.The analysis conclusion is verified by disassembly inspection and the fault location is identified.According to the fault reason,the improvement measures are presented.
