The invention discloses a transformer residual life prediction method and device, equipment and a storage medium. The method comprises the steps that the working current, the working voltage and the working oil temperature of a target transformer are acquired; performing Bayesian updating on the working current, the working voltage and the working oil temperature of the target transformer to obtain prior information of the target transformer; establishing a general path model of the target transformer according to the prior information and the working current, the working voltage and the working oil temperature of the target transformer; and according to the general path model, obtaining an optimal prediction parameter so as to predict the residual life of the target transformer. Therefore, working data of the target transformer are collected, a general path model is established, optimal prediction parameters are obtained, the residual life of the transformer is accurately predicted, and loss caused by sudden
