摘要
笔者应用气相色谱分析技术中的成分超标法I、EC三比值法以及平衡判据法成功地判断出一台主变压器B相内部所存在的突发性电弧放电故障。变压器停运后吊罩检查结果与气相色谱分析诊断结论相吻合,验证了气相色谱分析技术诸方法的正确性及有效性,为大型变压器的运行和异常判断提供了经验。
A sudden arc discharge fault in a 500 kV transformer was detected by means of the dissolved gas analysis method, and the check result confirmed the detection. The accuracy and validity of this method was therefore verified. In addition, some useful experiences for fault diagnosis in large transformer were provided.
