Abstract

This application relates to an oil-immersed transformer, which relates to the field of transformers. It includes an oil tank and a number of heat dissipation fins. The oil tank is provided with an accommodation cavity. The outer wall of the oil tank is provided with an oil guide tube. At the oil outlet, an oil pump is also arranged on the oil guide pipe. Control the oil pump to drive the oil in the oil tank to enter from the oil inlet and then discharge from the oil outlet. Part of the heat carried by the oil is dissipated into the air through the oil guide pipe, which increases the contact area between the heat and the air, and part of the heat is transferred to the air. The heat dissipation fins speed up the transfer of heat to the heat dissipation fins, further accelerate the heat dissipation, and delay the temperature rise of the oil tank, thereby improving the heat dissipation performance of the transformer and reducing the situation that the internal overheating of the transformer affects the operation of the transformer, which is beneficial to prolong the life of the transformer. The service life of the internal components of the transformer can reduce the frequency of transformer damage and scrapping, reduce material waste, and have a certain energy-saving effect.

Description

technical field [0001] The present application relates to the field of transformers, and more particularly, to an oil-immersed transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage, including distribution transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, and single-phase transformers. [0003] At present, oil-immersed transformers are mostly used. Oil-immersed transformers are transformers filled with transformer oil, which realizes insulation and cooling functions through transformer oil. It has the characteristics of low loss, large capacity and low price. [0004] After the oil-immersed transformer works for a long time, its internal oil temperature will rise, and if it is in a high temperature state for a long time, it may cause the winding temperature in the oil-immersed transformer to exceed the insulation tolerance ...
