The invention provides a transformation method for an air cooling system of an oil-immersed transformer, relates to the technical field of transformer cooling, and is used for improving a forced oil circulation air cooling system of a large oil-immersed transformer, and the transformation method comprises the step of transforming the transformer cooling system from an original cooler into a three-stage cooling structure of a finned radiator, a fan and an oil pump. According to the transformation method for the air cooling system of the oil-immersed transformer, a three-stage cooling system of oil-immersed self-cooling, oil-immersed air cooling and forced oil air cooling is transformed on the basis of forced oil circulation of an original transformer oil pump, different cooling modes are allowed to be switched under different load conditions according to needs, and the adaptability of the air cooling system of the transformer is improved; and meanwhile, under the condition that a secondary power supply fails a
