Circulating oil heat dissipation type low-noise transformer

Abstract

The invention discloses a circulating oil heat dissipation type low-noise transformer. The transformer comprises a hollow transformer shell and two fixing plates, wherein the two fixing plates are arranged in the transformer shell, a plurality of iron cores are welded to the side walls of the sides, which are close to each other, of the two fixing plates, pore plates are glued to the side walls ofthe sides, which are opposite to each other, of the two fixing plates through insulating supports; a plurality of springs are fixedly connected between the pore plate and the inner wall of the transformer shell; the transformer shell is fixedly connected with a circulating oil pipe in a penetrating mode, the two ends of the circulating oil pipe extend into the transformer shell in a penetrating mode, the section, which is located outside the transformer shell, of the circulating oil pipe is coiled on the outer side wall of the transformer shell in an S-shaped mode, and a plurality of coolingfins are welded to the outer side wall of the transformer shell. The transformer has the advantages that forced circulation of transformer oil is achieved without an oil pump, noise is reduced while abetter cooling effect is achieved, the transformer can be monitored in real time, and burnout caused by overheating of the transformer is avoided.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a circulating oil cooling type low-noise transformer. Background technique [0002] A transformer is a common electrical device in our life. It is a device that converts a certain value of AC voltage into one or several voltages with the same frequency. Generally, the voltage is increased through the transformer during the transmission process to reduce the transmission process. For the loss of electric energy, the high voltage is reduced to low voltage at the place where the users are concentrated, and the transformer itself also loses electric energy during the process of transforming the voltage. Part of the lost electric energy is converted into internal energy, which makes the temperature of the transformer rise. Therefore, the transformer needs certain cooling measures. [0003] In the prior art, the existing transformers generally adopt oil-immersed transformers, ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art that the heat dissipation effect of the transformer is not good, the transformer noise is too large, and the transformer is burned due to the lack of a good monitoring device, and a circulating oil heat dissipation type low-noise transformer is proposed.
