Diagnosis and Analysis of Abnormal Oil Chromatography of High Voltage Reactor

Reactors play an important role in reactive power compensation and harmonious filtering of the AC system, as well as limiting fault current, stabilizing the DC ripple and restraining commutation failure of the DC system. An abnormal oil chromatography of the high-voltage reactor is analyzed in this paper. Through on-site detection, return to factory disassembly and simulation analysis, it is determined that there is foreign matter discharge between the reactor side yoke baffle and the upper yoke, resulting in rapid growth of hydrogen. The analysis results provide a basis for the troubleshooting of the same type of high resistance hidden dangers and provide a guarantee for the safe operation of the power system.
