摘要
分析了IEC三比值法和大卫三角形故障诊断理论中特征气体比值集合划分和编码,结合几个特征气体产气量关系和发展趋势。
The set partition and its code of characteristic gas ratio in IEC and Duval triangle are analyzed. Based on the gas production rate and its trend of several characteristic gasses, the correctness of fault codes in national standard and industry standard is arguesed.
