Novel oil-immersed transformer

Abstract

The invention discloses a novel oil-immersed transformer in the technical field of oil-immersed transformers, which comprises a transformer body, and a heat dissipation mechanism for accelerating the heat dissipation efficiency of a heat dissipation plate is arranged on the outer side of the transformer body. The side wall of the transformer body is connected with a rotating mechanism used for driving the heat dissipation mechanism to rotate around the transformer body, and the rotating mechanism is matched with the heat dissipation mechanism to rapidly dissipate heat around the transformer body. Each time when the transformer body works with high load and generates heat severely, the rotating mechanism is started and drives the heat dissipation mechanism to move around the transformer body, so that the heat dissipation mechanism rapidly drives air on the outer side of the transformer body to conduct contact heat exchange on the transformer body, the transformer is rapidly cooled, the heat dissipation is mild, and the adverse effects on the transformer body are avoided. And the heat dissipation mechanism is simple in structure, integrated with the transformer body and small in occupied area, and the transformer body is convenient to install and use.

Description

technical field [0001] The invention relates to the technical field of oil-immersed transformers, in particular to a novel oil-immersed transformer. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: distribution transformer, fully sealed transformer, combined transformer, dry-type transformer, oil-immersed transformer, single-phase transformer, etc. Among them, the oil-immersed transformer has the characteristics of low loss, large capacity and low price. [0003] When the oil-immersed transformer in the prior art works for a long time, the temperature of the cooling oil will rise rapidly, which will easily cause the internal heating of the oil-immersed transformer, easily damage the ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a new type of oil-immersed transformer to solve the problem that the oil-immersed transformer of the prior art in the above background technology will cause the temperature of the cooling oil to rise rapidly when it works for a long time, which will easily lead to the oil-immersed transformer. The internal heating of the transformer is easy to damage the windings inside the transformer, accelerate the aging of components, and cause damage to the transformer. However, the existing oil-immersed transformers use cooling oil and heat dissipation plates to dissipate heat, and the heat dissipation effect is poor. When the oil temperature rises, it cannot be cooled quickly, so there is an urgent need for a new type of oil-immersed transformer that can quickly dissipate heat
