摘　　要：2006年通过色谱监督发现并确诊了4号主变内部存在高温过热故障的重大隐患,随后进行了60多天的连续跟踪监测,得到了详实、准确的数据,为今后更好地进行气相色谱监测,以保证大型电气主设备绝缘安全积累了经验。In 2006, incipient fault caused by overheating fault inside No. 4 main transformer has been found out and confirmed by using chromatogram supervision. A more than 60 days monitoring has been conducted later on. The detailed and correct data has been collected to ensure a better meteorological chromatogram supervision and richer experience on insulation safety of large main electric equipment.
