Abstract

The invention belongs to the field of transformers, and particularly relates to an oil-immersed three-phase transformer. In the prior art, cooling fins are used for heat dissipation, but the cooling fins are generally arranged inside; or heat is dissipated through vent holes, but the heat dissipation efficiency is not high, and the open vent holes enable dust to easily enter a transformer to damage the transformer. In order to solve the problems, a scheme as follows is put forward: the oil-immersed three-phase transformer comprises a transformer shell of a hollow structure, an oil tank is fixedly installed at the top of the transformer shell, and an oil inlet pipe and an oil outlet pipe are fixedly installed in the transformer shell. The transformer is simple in structure and convenient tooperate. Heat generated in the working process of the transformer body can be dissipated, heat can be dissipated even when the external temperature is high, and normal work of the transformer body isguaranteed. Meanwhile, after heat dissipation is completed, heat dissipation openings can be sealed, so that dust is prevented from entering the transformer, and the requirements of people are met.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an oil-immersed three-phase transformer. Background technique [0002] The three-phase transformer is a complete set of transformation equipment, which can be used for terminal power supply and ring network power supply. The conversion is very convenient and ensures the reliability and flexibility of power supply. However, the transformer will generate a lot of heat during operation. The traditional transformer dissipates heat Mainly by setting air passages or oil passages in the body, the heat is taken away by the circulating flow of gas or oil to dissipate heat. Its structure is complex, manufacturing and maintenance is difficult, and it is highly specific to the type of transformer and does not have universal applicability; [0003] Traditionally, heat sinks are also used to dissipate heat, but the heat sinks are usually installed inside to dissipate the heat through the ...
