摘要
The parallel oil immersed reactor of 750 kV ultra-high voltage can improve the reactive power operation state of the 750 kV line. When the 750 kV line is lightly empty or lightly loaded, the line has capacitance effect, which can be used to reduce the power frequency transient overvoltage and improve the voltage distribution. This is the reason why the high voltage reactor of Hehu II line in Helanshan 750 kV substation was installed and put into operation. The oil chromatogram of phase C high-voltage reactor of the line is detected offline regularly, and abnormal data is found. Through the analysis of field detection test, diagnostic test and multi physical field simulation, the problem reproducibility is verified, the causes of abnormal faults are determined, and finally the measures to prevent similar faults are put forward.
