Description
Technical Field
The utility model is suitable for the field of transformer equipment and provides an oil immersed transformer with efficient heat dissipation.
Background
A transformer is a stationary electrical device for transforming ac voltage and current to transmit ac power. The electric energy transmission is realized according to the principle of electromagnetic induction. The transformer can be classified into a power transformer, a test transformer, an instrument transformer, and a special-purpose transformer in terms of its uses. The cooling of the transformer means that heat generated by the running transformer is emitted by a certain method, and when the transformer runs, heat generated by loss in a winding and an iron core must be timely dissipated so as to avoid insulation damage caused by overheating. Since the loss of a transformer is proportional to its volume, as the capacity of the transformer increases, its volume and loss will increase to the third power of the core size, while the outer surface area increases only to the second power of the size. Therefore, the large-capacity transformer core and windings should be immersed in oil, and most distribution transformers and many power transformers adopt the oil-immersed self-cooling mode.
The oil immersed transformer is arranged in the oil tank to cool down through cooling oil in the oil tank, and meanwhile, the cooling oil dissipates heat through cooling fins on the oil tank. Because the intervals of the radiating fins are smaller, when natural wind is used for ventilating the radiating fins for cool air, the natural wind is difficult to blow to the radiating fins in the middle part. The cooling water in the existing water-cooling heat-dissipation type oil immersed transformer has limited heat dissipation effect in the circulation process, and when the temperature of the oil immersed transformer is higher, the temperature of the cooling water rises, heat exchange is not easy to perform, and the heat dissipation effect is limited.
