Level-1-energy-efficiency oil-immersed energy-saving transformer

Abstract

The invention relates to the technical field of oil-immersed energy-saving transformers, in particular to a level-1-energy-efficiency oil-immersed energy-saving transformer. The level-1-energy-efficiency oil-immersed energy-saving transformer comprises a transformer body. The top of the transformer body is bolted with a cover body; front radiating fins are welded to the front side and the rear side of the transformer body respectively; side radiating fins are welded to the left side and the right side of the transformer body respectively; supporting frames are welded to the two sides of the top of the transformer body; an oil outlet is formed in one side of the bottom of the transformer body in a penetrating mode; and an oil column runs through the cover body. The beneficial effects are that: cooling liquid in a cooling liquid tank is introduced into a heat dissipation cavity by utilizing an oil supply pump to make the cooling liquid take away the heat on the radiating fins; and finally, the cooling liquid in the heat dissipation cavity flows back to the cooling liquid tank, so that a cooling liquid circulation system is formed to uninterruptedly cool the radiating fins. Compared with the traditional technology, the heat dissipation efficiency of the radiating fins is obviously higher, the heating power of the transformer can be effectively reduced, and the energy loss of the transformer is reduced.

Description

technical field [0001] The invention relates to the technical field of oil-immersed energy-saving transformers, in particular to a first-class energy-efficiency oil-immersed energy-saving transformer. Background technique [0002] Oil-immersed transformers are mainly composed of iron cores, windings, oil tanks, oil pillows, insulating bushings, tap changers, and gas relays. The iron cores and windings are all immersed in transformer oil, which plays the role of insulation and cooling. The role of reducing the energy loss of the transformer during operation. Existing oil-immersed transformers mainly arrange cooling fins in four directions, front, rear, left, and right of the box body, so as to increase the surface area of ​​the box body to improve heat dissipation efficiency. But even so, under the premise of high-load operation of the transformer, its internal winding coil will generate heat, which will also generate a lot of heat, which will increase the overall temperatur...

Problems solved by technology

But even so, under the premise of high-load operation of the transformer, its internal winding coil will generate heat, which will also generate a lot of heat, which will increase the overall temperature of the transformer. Over time, it will affect the performance of each component inside the transformer and increase the transformer. Loss, it is difficult to meet the standard of first-class energy efficiency

[0003] In addition, the existing transformer oil is filled inside the transformer casing, and the top of the transformer is connected with a cover by bolts. This arrangement obviously lacks a sealing structure, and as the service life increases, the transformer oil will gradually leak from the transformer casing. Seepage in the gap is not conducive to the safe use of the transformer. Therefore, the present invention proposes a first-level energy-efficiency oil-immersed energy-saving transformer to solve the above problems
