Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a three-dimensional oil-immersed transformer oil tank. Background Art

[0002] The oil tank is the outer shell of the oil-immersed transformer, which is used to dissipate heat and protect the body of the transformer. The body of the transformer is placed in the oil tank, and transformer oil for insulation and heat dissipation is placed in the oil tank. Existing oil-immersed transformer oil tanks mostly use heat sinks for air cooling. However, for transformers with larger capacity, the heat increase caused by electromagnetic loss is large. Relying solely on the heat sink of the oil tank for heat dissipation has the risk of untimely heat dissipation. If the temperature is to be controlled within a reasonable range, it is necessary to further increase the transformer oil tank and the amount of transformer oil in the oil tank, which makes the oil tank too large, inconvenient to use, and increases the cost.
