Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer heat dissipation, in particular to an oil tank structure with a heat sink. Background Art
[0002] Transformer is an indispensable equipment in the power system. It can convert high voltage into low voltage, or convert low voltage into high voltage. During the operation of the transformer, the conversion of electric energy is inevitably accompanied by energy loss and heat generation. If the transformer is in a high temperature state for a long time, it will have an adverse effect on its performance, life and stability. Therefore, heat dissipation is crucial to the operation of the transformer. Transformer radiator refers to a heat dissipation device used for transformer cooling, which is an important component for dissipating the heat generated by the transformer. Through the heat dissipation of the radiator, the normal operation of the transformer can be guaranteed and its service life can be extended. Since the loss of the transformer is proportional to its volume, as the capacity of the transformer increases, its volume and loss will increase by the cube of the core size, while the surface area will only increase by the square of the size. As the capacity of the transformer increases, in order to reduce the temperature rise of the transformer, it is necessary to add a radiator to the transformer, and the overall cost of the transformer increases. In order to effectively reduce the transformer tank structure, we propose a transformer tank structure with a heat sink. Utility Model Content
