Zusammenfassung:The invention discloses a transformer bushing residual life prediction method considering water content accelerated aging, and relates to the technical field of transformer bushing life prediction, and the method comprises the following steps: collecting offline data and online data of a transformer bushing, and constructing a water content data simulation model of the transformer bushing, the on-line data represents first physical characteristic data of the transformer bushing, and the off-line data represents second physical characteristic data of a space where the transformer lasso is located; based on the water content data simulation model, acquiring a water accelerated aging factor coefficient by analyzing the accelerated influence of water on insulation aging of the transformer bushing; based on the aging dynamic model of the transformer bushing, a prediction model is constructed by introducing a moisture accelerated aging factor coefficient, and the residual life of the transformer bushing is predicte
