PROBLEM TO BE SOLVED: To provide an oil-filled transformer which achieves space saving by preventing a radiator from becoming extremely large and efficiently radiates heat occurring therein to an exterior part.SOLUTION: An oil-filled transformer 10 includes: a transformer tank 11; an iron core 12 disposed in the transformer tank; and a coil 13 wound around an outer peripheral surface of the iron core; a radiator 14 which is disposed on an outer wall surface of the transformer tank through an oil tube 15; and an insulation oil filling the transformer tank. Further, a thermoelectric element 19 is disposed so as to thermally contact with at least one part of the oil-filled transformer. |
