Abstract:Taking the abnormal noise generated during the operation of a 500kV line high-voltage shunt reactor as an example, the abnormal noise fault processing process is recorded in detail, and the cause of abnormal noise generated by the high-voltage shunt reactor is analyzed, and an effective means to deal with such problems is proposed. According to infrared temperature measurement, insulation resistance test, oil chromatography off-line analysis and other methods, it can be determined whether the abnormal noise originates from the inside of the body. According to the vibration test, noise test and equipment operation, it is judged whether the abnormal noise originates from the external fault of the equipment. Through a variety of detection methods and comprehensive analysis,it is found that the source of abnormal sound is caused by the metal welding residue in the pressure ring of the high-voltage parallel reactor and the looseness of the body parts. According to the fault analysis and processing method of 500kV line high voltage shunt reactor abnormal sound, the reliable measures of equipment maintenance and repair are summarized, and the effective means of fault diagnosis is put forward. It has certain reference significance for the initial judgment of the operation personnel. It is helpful for maintenance personnel to take corresponding measures to avoid blind maintenance.
