Transformer fault diagnosis method, system and equipment and storage medium

The invention provides a transformer fault diagnosis method, system and device and a storage medium, and belongs to the technical field of transformer fault diagnosis. The method comprises the steps of obtaining operation information of a transformer; determining the operation information meeting the corresponding fault condition in the operation information of the transformer as effective operation information of the transformer; based on a preset transformer fault set and the effective operation information of the transformer, probability statistics is carried out, and at least one transformer fault result corresponding to the effective operation information of the transformer is determined; and matching the at least one transformer fault result with a preset fault processing measure mapping relation table and a preset fault type mapping relation table, and determining at least one transformer fault processing measure and a transformer fault type corresponding to the transformer fault result.
