Converter transformer fault monitoring and warning device, method, recording medium and system

The invention belongs to the technical field of electrical detection, and particularly relates to a converter transformer fault monitoring and warning device and method, which form advantage complementation based on different monitoring means such as oil chromatography, rapid oil chromatography, single hydrogen, acoustoelectric combination and the like, mutually verify monitoring data, and formulate a multi-dimensional and time-space fusion fault diagnosis early warning strategy. Reliability of monitoring data, accuracy of fault diagnosis and timeliness of early warning maintenance are realized, terrible accidents caused by further development of faults are avoided, safe and stable operation of a power grid is guaranteed, and the method is especially suitable for on-line monitoring of a large converter transformer. The invention also provides a non-transitory readable recording medium storing the program of the method and a system comprising the medium, and the program can be called through a processing circu
