Analysis and Treatment on a Heating Fault of 110 kV Transformer Bushing

doi:10.3969/j.issn.1008-0198.2022.01.020

Abstract

Abstract: In this paper, a heating fault of 110 kV transformer bushing is found through infrared temperature measurement. The process of fault inspection and treatment is introduced, and the reason of the heating fault is analyzed. The analysis result shows that the missing of inclined coil spring is the direct cause of this fault, and transformer operates normally after rectification. Finally, suggestions are put forward for analysis and treatment of such faults.

Key words: transformer bushing, infrared temperature measurement, heating fault, fault analysis
