Embodiment Construction

[0026] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0027] A transformer impregnation method, comprising the steps of:

[0028] ①Put the transformer in an oven to dry for 4 hours, and control the temperature at 10°C lower than the boiling point of the paint solvent;

[0029] ② Take out the transformer while it is hot and immerse it in the paint solution at room temperature for 0.5 hours;

[0030] ③Take out the transformer and let it dry for 1 hour;

[0031] ④ Place the transformer in an oven to dry.

[0032] The principle of the present invention is: appropriately increase the temperature during dipping to reduce the viscosity so as to increase the content of solid matter (lacquer base) in the transformer void. When the insulating varnish suddenly arrives at high temperature, the organic solvent has not had time to volatilize, and the linear resin molecules in the insulating varn...

Abstract

The invention provides a transformer impregnating method. The method includes the steps of 1, drying a transformer in a drying box, at the controlled temperature 5 to 15 DEG C lower than a boiling point of paint solvent; 2, extracting the transformer when it is hot, and impregnating the transformer in paint at room temperature; 3, extracting the transformer, and drip-drying the same; 4, drying the transformer in the drying box. The method has the advantages that the process time is short, insulation degree of the transformer is increased, production efficiency is improved, energy consumption is lowered, and equipment investment is none.

Description

technical field [0001] The invention relates to a transformer impregnation method, which belongs to the field of transformer processing. Background technique [0002] Transformers are an indispensable part of electronic products, and the insulation degree of transformers determines the length of life of transformers. By impregnating the insulating varnish, after curing at high temperature, the solids contained in the insulating varnish are left in the gap of the transformer to increase the insulation of the transformer. The degree of insulation is determined by the filling rate of the solids in the transformer gap. The higher the filling rate, the higher the filling rate. The greater the degree of insulation. So far, vacuum impregnation, pressure impregnation or vacuum-pressure impregnation has been used for transformer impregnation. [0003] It is difficult to increase the solid content in the transformer gap, whether it is vacuum impregnation, pressure impregnation, or v...
