The working principle of the invention is as follows: when the temperature of the transformer 2-1 rises, the temperature of the compressed air in the compressed air fixing half-sealed cylinder 6-1 rises, the air pressure is increased, the increased air pressure drives the telescopic shaft 6-5 to move outwards in the two sealing partition plates 6-3 through the sealing sliding of the two sliding sealing rings 6-4, and the telescopic top plate 6-6 extrudes the driving top plate 3-1; when the limiting condition is to be adjusted according to different temperatures, the adding condition of compressed air in the fixed semi-sealed cylinder 6-1 of the compressed air can be adjusted, or the displacement of the transformer 2-1 can be adjusted by rotating the two adjusting bolts 2-4, so that the extrusion condition of the telescopic top plate 6-6 on the driving top plate 3-1 and the two springs 3-3 is adjusted, and the limiting condition to be cooled is adjusted; the telescopic top plate 6-6 is extruded outwards to drive the top plate 3-1 through the increased air pressure, so that the two springs 3-3 are extruded, and meanwhile, the two top plate spring shafts 3-2, the front rack connecting plate 3-4, the two front T-shaped sliding blocks 3-5 and the two driving racks 3-6 all move forwards; the two driving racks 3-6 which move forwards drive the two driving gears 4-1 to rotate, so that the two side rotating shafts 4-2 and the two driving turntables 4-3 rotate, the upper sliding door 4-7 and the lower sliding door 4-8 are driven to slide in the two door limiting sliding seats 4-9 through the two driving hinge rods 4-4, the upper hinge seat 4-5 and the lower hinge seat 4-6 simultaneously, and the front ventilation groove 1-2 is opened to facilitate air inlet of the outdoor front for cooling; two driving racks 3-6 which simultaneously move forwards drive the closed side door leaves 5-1 to rotate on the side door hinge seats 5-2 through the fixed connecting seats 5-4 and the hinge rods 5-3, so that all the side door leaves 5-1 are separated from the plurality of side ventilation slots 1-3, outdoor air passes through the plurality of side ventilation slots 1-3 and the two inner wall interval ventilation plates 1-6, and the temperature of the transformer 2-1 with high temperature is reduced; when the transformer 2-1 is gradually lowered, the two driving racks 3-6 are gradually restored to the original positions and are displaced backwards by the acting force of the two springs 3-3, so that all the side door 5-1 are gradually closed, the upper sliding door 4-7 and the lower sliding door 4-8 are gradually closed, and the protection box body 1-1 is closed again after the temperature is reduced to the designated temperature; the transformer 2-1 is subjected to closed protection, and then self-cooling is realized; when the temperature is high, the closed protection shell is automatically opened for ventilation, and when the temperature is not normal, the closed protection shell effectively protects the transformer located outdoors; the displacement distance and the position of the transformer can be adjusted according to the actual condition of the temperature of the transformer, and then adjustment is carried out according to different actual temperature conditions; through the self-adjustment of transformer temperature, avoid the use at outdoor electric power, convenient and practical.
The above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and variations, modifications, additions and substitutions which may be made by those skilled in the art within the spirit of the present invention are within the scope of the present invention.
