when the air in the pressure relief box 6 is increased due to pressure relief, the pressure relief plate 17 is extruded to move downwards in the pressure relief box 6, and when the pressure relief plate 17 moves downwards, the supporting spring 18 is driven to synchronously compress and move downwards, and then the lifting pressing plate 19 is driven to move downwards, and the lifting pressing plate 19 moves downwards to extrude the synthetic ester oil at the lower part of the pressure relief plate to automatically extrude the synthetic ester oil.
The synthetic ester oil in the pressure release box 6 is poured into the liquid guide tube 12 when being extruded, so that the piston frame 14 in the liquid guide tube 12 is pushed to move, and the displacement plate 20 is driven to synchronously move when the piston frame 14 moves, even if the displacement plate slides on the supporting top plate 7;
the displacement plate 20 can drive the transmission toothed bar 24 to move when moving, the transmission toothed bar 24 can drive and rotate a plurality of transmission gears 23 and a plurality of driven rollers 21, and a plurality of induced air cooling fins 22 can be driven to rotate when a plurality of driven rollers 21 rotate, so that the deflection angle of the induced air cooling fins 22 can be adjusted, the induced air cooling fins are more easily affected by wind, and the heat dissipation efficiency is improved.
When the induced air cooling fin 22 rotates, the linkage plate 25 is pushed to move, and when the linkage plate 25 moves, the folding baffle plate 8 on the linkage plate is driven to move and compress, so that the shielding range of the folding baffle plate 8 to the cooling port 5 is reduced, the cooling ventilation range of the cooling port 5 is improved, the overall ventilation efficiency of the explosion-proof housing 1 is improved, the cooling efficiency of the cooling fin 3 and the induced air cooling fin 22 is improved, the temperature of the explosion-proof housing 1 and the transformer main body 2 is reduced in a cooling manner, and the explosion risk of the transformer main body 2 is reduced.
The synthetic ester oil in the pressure relief box 6 is poured into the radiating pipe 9 when being extruded, and is accumulated on the side part of the pushing disc 30 in the radiating pipe 9, and along with the gradual increase of the synthetic ester oil, the pushing disc 30 gradually moves under the pushing of the synthetic ester oil and drives the trigger rod 31 to touch the trigger button 32, and at the moment, the trigger button 32 is triggered, so that the servo motor 34 is controlled to start;
the servo motor 34 is started to drive the driving roller 35 to rotate, the driving roller 35 drives the plurality of air impellers 29 on the driving roller to rotate when rotating, the air impellers 29 suck cold air outside the explosion-proof housing 1 into the radiating pipe 9 through the induced air dust filtering box 4, wind power air flow is formed in the radiating pipe 9 and then is led into the air guiding box 10 through the upper air pipe 28, and when the air in the air guiding box 10 increases, the air is blown out vertically downwards through the plurality of blowing pipes 26;
The wind power air current in the blowpipe 26 can carry out the pertinence to two radiating fins 3 of its both sides and blow, can dispel the heat efficiency of radiating fins 3 fast, and the wind power air current that the blowpipe 26 bloied produced can circulate in the circulation wind groove in explosion-proof shell 1 simultaneously to can further accelerate the radiating effect of explosion-proof shell 1 and transformer main part 2 when flowing, thereby reduce the temperature of transformer main part 2 fast, realize the inside step-down of transformer main part 2, reduce its risk of explosion, realize effectual explosion-proof protection.
The embodiment of the invention also provides a use method of the station explosion-proof transformer with high safety, which is used for the station explosion-proof transformer with high safety and comprises the following steps:
s1, performing targeted pressure monitoring on the inside of a transformer main body 2 through a plurality of pressure monitoring sensors 15, and monitoring whether the pressure in the transformer main body 2 exceeds a standard in real time;
s2, if the pressure is monitored to be large, targeted deflation and pressure relief of the area are carried out through the pressure relief assembly;
S3, pressure relief is carried out, and the unfolding states of a plurality of folding baffles 8 in the adjusting assembly are adjusted through the pressure relief assembly according to the pressure, so that the natural heat dissipation efficiency of the inside of the transformer main body 2 is improved;
S4, pressure relief is simultaneously started through the pressure relief assembly driving heat dissipation assembly according to the pressure, and the heat dissipation fins 3 are blown and dissipated in a targeted mode through the blowpipes 26, so that the pressure relief of the transformer main body 2 is promoted through cooling, and the explosion-proof safety of the transformer main body 2 is improved.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
