Multifunctional transformer

The utility model discloses a multifunctional transformer which comprises a base, a bin body is fixedly installed on the top of the base, a transformer body is fixedly installed on the inner wall of the bin body, insulation heat dissipation oil is contained in the bin body, and a heat exchange assembly is fixedly installed on the outer wall of the bin body. The heat exchange assembly comprises a self-priming pump used for circulating insulation heat dissipation oil and fan blades used for conducting heat exchange on the insulation heat dissipation oil, the transformer body can be conveniently installed in the insulation heat dissipation oil by arranging the heat exchange assembly, so that liquid cooling can be conveniently conducted on the transformer body through the insulation heat dissipation oil, and the heat exchange efficiency is improved. And meanwhile, when the temperature of the transformer body is too high, the insulating heat dissipation oil is pumped out through the self-priming pump, then air coo
