Transformer box body structure with circulating cooling function

Abstract

The invention provides a transformer box body structure with a circulating cooling function, belongs to the technical field of transformer boxes, and is used for solving the problems of poor cooling effect and low efficiency of an existing transformer box. The transformer box body structure comprises a box body and a box cover, the box cover is fixed on the box body through a plurality of mountingbolts, and an oil storage rack is fixed at the upper end of the box cover. An oil conservator is fixed at the upper end of the oil storage rack, an oil guide pipe is connected between the oil conservator and the box cover, and a plurality of first radiating fins are fixed at the left and right sides of the box body. A plurality of second cooling fins are fixed to the front side and the rear sideof the box body, a circulating air cooling mechanism, a circulating water cooling mechanism and a return oil cooling mechanism are arranged at the periphery of the box body, and the return oil coolingmechanism comprises an oil pump. A return oil valve is fixed at the right side of the box body, the oil inlet end of the oil pump is connected to the return oil valve through a return oil capillary,and the oil outlet end of the oil pump is connected to the oil conservator through a return oil capillary. The transformer box body structure can carry out air cooling, water cooling and oil cooling circulation heat dissipation and cooling efficiently, the heat dissipation and cooling effect is good, the efficiency is high, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of transformer boxes, and relates to a transformer box, in particular to a transformer box structure with a cooling function. Background technique [0002] The box-type transformer is a combination of traditional transformers and other accessories installed in a box-type housing, making it a compact, light-weight, and easy-to-install variable voltage power supply system. The box-type transformer is not just a transformer, it is equivalent to a small substation distribution station, which can directly provide power to users. [0003] Wet transformer, also known as oil-immersed transformer, is a structural type of box-type transformer. Unlike dry-type transformers, the coils of wet-type transformers are soaked in oil. Commonly used are silicone oil, diesel oil, etc. Oil-immersed transformers are generally installed indoors or outdoors in separate transformers due to the need for fire prevention. They have the...

AI Technical Summary

Problems solved by technology

[0004]The box body of the existing wet-type transformer is relatively large. When the electrical components are in operation, losses such as copper loss and iron loss will occur, and the loss will generate a lot of heat. The windings, electrical components and lines are installed compactly, the heat dissipation effect is not good, and it is difficult to cool down in time after the silicone oil is heated up, so that the transformer windings are kept at a high temperature level for a long time, the working state is not very stable, and the life of the coil will be greatly shortened
