The application discloses an on-line monitoring device and method for dissolved gas in transformer oil based on infrared spectrum, which comprises a transformer oil gas separation part, an infrared spectrum gas detection part and a data processing part. The method comprises the following steps: firstly, carrying out oil gas separation; then, sending the obtained dissolved gas in oil into a gas chamber and scanning the gas chamber by using an infrared spectrometer to obtain a spectrum diagram; and finally, obtaining the content of various target gases in oil by using a gas quantitative analysis model. The application uses infrared spectrum method as the gas detection part, has the advantages of fast spectrum data acquisition, no consumption of gas samples, wide detection range, high stability, maintenance-free, long-term operation monitoring cost, etc. compared with the most widely used gas chromatography method for on-line monitoring of gases in transformer oil. The device adopts a structure based on single-chamber vacuum degassing, solves the problem of spectrum baseline offset distortion, and does not need to consume nitrogen as background, thereby improving the automation degree of the device.
