Oil-immersed transformer aging fault identification method based on data analysis

The invention discloses an oil-immersed transformer aging fault identification method based on data analysis, and relates to the technical field of transformer aging fault identification, and the method comprises the following steps: collecting a historical data set Uz of furfural content corresponding to the operating age limit of an oil-immersed transformer; and establishing a furfural content coordinate analysis model corresponding to the operating age limit of the oil-immersed transformer, and importing the obtained historical data set Uz into the coordinate analysis model to obtain a regional distribution model diagram of the furfural content corresponding to the operating age limit of the oil-immersed transformer on the coordinate analysis model. According to the invention, the method achieves the recognition of the abnormal aging state change condition of the target oil-immersed transformer, achieves the recognition of the aging state of the target oil-immersed transformer and the abnormality of the no
