[0062] Under normal operation of power transformers, due to the aging of internal insulating solids, a small amount of gas will be dissolved in insulating oil, mainly hydrogen (H 2 ), methane (CH 4 ), ethane (C 2 h 6 ), ethylene (C 2 h 4 ), acetylene (C 2 h 2 ), carbon monoxide (CO), carbon dioxide (CO 2 ) and other gases. According to the different proportions of dissolved gas in the oil, different operating conditions of the transformer can be distinguished, for example: hydrogen H gas when high-energy discharge is generated 2 and acetylene C 2 h 2 The content of will increase; When running into the situation of intense magnetic field, the content of hydrocarbon gas will increase, and show certain correlation, the present invention selects hydrogen (H 2 ), methane (CH 4 ), ethane (C 2 h 6 ), ethylene (C 2 h 4 ), acetylene (C 2 h 2 ), carbon monoxide (CO), carbon dioxide (CO 2 ) and other seven gases are used as characteristic parameters.
