OIL TRANSFORMER |
| 摘要 |
An oil transformer includes a transformer vessel, a transformer core mounted in the vessel, at least one upright hollow cylindrical transformer coil including at least one axial cooling channel arranged around a limb of the transformer core, and an oil chamber arranged at an axial front side of the transformer coil. At least one first opening leading from the inner chamber to the belonging front side of the transformer coil is provided, and at least one second opening is provided within the surrounding boundaries of the oil chamber. The oil chamber is an under-pressure chamber, wherein the at least one first opening is an inlet port and the at least one second opening is an outlet port. |
