Transformer detection method and device based on ethylene signal, equipment and storage medium

The invention relates to a transformer detection method and device based on an ethylene signal, computer equipment and a storage medium. The method comprises the following steps: introducing ethylene gas with known concentration into a White cell, and calculating a primary relationship between a peak value of a second harmonic gas absorption peak of ethylene and the concentration; detecting the concentration of ethylene gas separated from a transformer and dissolved in oil by utilizing a TDLAS technology, and reversely deducing the concentration of the ethylene gas according to the relationship between the peak value of a second harmonic gas absorption peak and the concentration; and determining fault information of the transformer according to the calculated ethylene gas concentration. A Butterworth filter and TDLAS signal processing are combined, and the influence of noise in second harmonics on an absorption peak is reduced. Therefore, the detection of the final ethylene becomes very accurate, the fault an
