Problems solved by technology
[0004] The purpose of the present invention is to provide an oil-immersed transformer based on a cooling protection device to solve the problem that most of the insulating and cooling oil inside the oil-immersed transformer proposed in the background technology cannot be replaced effectively and quickly, which makes the insulating and cooling oil last for a long time. It is easy to deteriorate inside the transformer, and its cooling and insulation effects will be greatly reduced, which will lead to the reduction of the overall working efficiency of the transformer.

The invention discloses an oil-immersed transformer based on a cooling protection device, which comprises an outer metal shell of the transformer, an upper end plate is fixedly welded on the upper end of the outer metal shell of the transformer, a fixed plate is fixedly welded on one side of the upper surface of the upper end plate, and the fixed plate Both sides are fixed with a circular groove, and a metal end cap is fixedly placed in the circular groove. The lower end of the metal end cap is fixedly welded with an insertion pin, and the two sides below the two sides of the insertion pin are fixed with a mounting cavity. One end inside the installation cavity is fixedly welded with a small extension spring, one side of the small extension spring is fixedly welded with a limit block, and the outside of the inside of the installation cavity is fixedly welded with a limit block, and the two sides of the lower end of the insertion pin are fixed with limit stops card slot. The invention can effectively and quickly replace the insulating cooling oil inside the oil-immersed transformer, and can quickly disassemble and install when the oil filling metal nozzle is damaged.
Description
technical field [0001] The invention relates to the technical field of oil-immersed transformers, in particular to an oil-immersed transformer based on a cooling protection device. Background technique [0002] With the rapid development of social economy, distribution transformers are one of the important equipment in the power supply and distribution systems of industrial and mining enterprises and civil buildings. Oil-immersed transformers are widely promoted because of their excellent performance and low price. [0003] However, most of the insulating cooling oil inside the existing oil-immersed transformer cannot be replaced effectively and quickly, which makes the insulating cooling oil easy to deteriorate in the transformer for a long time, and its cooling and insulating effect will be greatly reduced, resulting in The reduction of the overall working efficiency of the transformer. Contents of the invention [0004] The purpose of the present invention is to provid...
