The invention relates to a transformer winding overall aging test method characterized by including the steps of 1) taking transformer oil, placing the transformer oil in a dry vacuum oven, and dryingthe transformer oil at 110-130 DEG C for 48-60 hours; 2) placing a model transformer winding in the dry vacuum oven and drying insulating material in the winding structure at 100-110 DEG C for 24-30hours; 3) mounting a load cell on the dried model transformer winding; and 4) immersing the dry model transformer winding equipped with the load cell in the dried transformer oil at 75-85 DEG C for 46-50 hours, requiring the immersion process to be in a vacuum environment and fully immersing the model transformer winding in the transformer oil during the immersion. The method of the invention cannot only accurately characterize the overall aging process, but also avoid the return and maintenance of a transformer in operation, thereby reducing the impact on the power grid.
