Abstract

The application discloses a gas spectrum identification method in transformer oil based on multispectral analysis and relates to the technical field of gas spectrum identification in transformer oil, and comprises the following steps: performing spectrum pretreatment on a spectrum diagram to obtain a spectrum calibration diagram; performing feature extraction on the spectrum calibration diagram; learning a judgment basis of a feature peak according to a spectrum feature; extracting gas combinations of a transformer under different working states, and analyzing to obtain characteristic reference data of the transformer under different working states; and performing identification analysis on the spectrum feature of the gas in the transformer oil based on the characteristic reference data, and judging the working state of the transformer; the application is used to solve the problems that the existing gas spectrum identification technology in transformer oil is prone to noise interference in spectrum diagram identification, the identification of overlapping feature peaks is not accurate, and the identification of the gas revealed in the spectrum diagram is not accurate.
