Oil-immersed transformer capable of automatically adjusting heat dissipation function

The utility model relates to the technical field of transformers, and discloses an oil-immersed transformer with an automatic heat dissipation adjusting function, the oil-immersed transformer comprises a transformer body, and a plurality of heat dissipation fins arranged at equal intervals are fixedly connected to the front and back of the transformer body. According to the oil-immersed transformer capable of automatically adjusting the heat dissipation function, through the arrangement of the first heat dissipation fan, external air can be conveyed into a dust screen, dust in the air is filtered through interception fins and a filter screen, and the situation that the dust covers the surfaces of the heat dissipation fins, so that contact between the heat dissipation fins and the air is affected is avoided; meanwhile, ventilation grooves among the multiple heat dissipation fins can form air channels, the heat dissipation efficiency of the transformer body is improved, heat conduction blocks and cooling pipes
