<p>The invention is related to an oil transformer (10), comprising a transformer vessel (12), a transformer core mounted (14) therein, at least one upright hollow cylindrical transformer coil (16, 18) with at least one axial cooling channel (34, 36) arranged around a limb (28) of the transformer core (14) and an oil chamber (20, 22, 60, 80, 90) arranged at an axial front side of the transformer coil (16, 18). At least one first opening (86, 87, 88) leading from the inner chamber (100) to the belonging front side of the transformer coil (16, 18) is foreseen and at least one second opening (70) is foreseen within the surrounding boundaries (64, 66, 94, 96) of the oil chamber (20, 22, 60, 80, 90). The oil chamber (20, 22, 60, 80, 90) is an under-pressure chamber, wherein the at least one first opening (86, 87, 88) is an inlet port and the at least one second opening (70) is an outlet (78) port.</p> |
