Abstract

Abstract: In Huadian Inner Mongolia Energy Corporation Limited, Baotou Power Generation Branch Company, after the B phase main transformer of unit No.2 was put into operation, during the periodical chromatographic analysis of the gas dissolved in the oil, it was found that the volume fraction of the total hydrocarbon was increasing continuously, and the absolute gas generation rate exceeded the warning value. It was judged that there is over temperature fault inside the transformer. The transformer was overhauled many times and had been transported to the manufacturing factory to repair, and the fault was found and eliminated finally; then the safe and stable operation of the transformer was ensured.

Key words: transformer, chromatographic analysis, total hydrocarbon, fault diagnosis
