Description

Technical Field

[0001] The present invention relates to the technical field of transformer equipment, and in particular to an energy-saving and environment-friendly dry-type power transformer. Background Art

[0002] Dry-type power transformers offer high electrical, mechanical, and thermal strength. They are excellent products for urban power grid transformation and are particularly suitable for critical locations requiring fire, explosion, and moisture protection, such as high-rise buildings, airports, power stations, and commercial centers. Dry-type transformers are widely used in areas such as local lighting, high-rise buildings, airports, and CNC machinery at ports. Simply put, a dry-type transformer is one whose core and windings are not immersed in insulating oil. Cooling methods include natural air cooling (AN) and forced air cooling (AF). Natural air cooling allows the transformer to operate continuously at rated capacity for extended periods. Forced air cooling increases the transformer's output capacity by 50%. They are suitable for intermittent overload operation or emergency overload conditions. However, due to the significant load loss and impedance voltage increase during overload, which results in uneconomical operation, extended continuous overload operation should be avoided.

[0003] With the development of my country's national economy, the continuous improvement of national environmental protection laws and regulations, and the increasing public awareness of environmental protection, the share of dry-type transformers in urban distribution transformers has rapidly increased.

A partition space is formed between the first support ring 5 and the second support ring 6, and the top of the first support ring 5 is fixed to the bottom of the box body 4. A heat dissipation port is provided at the bottom of the box body 4. After the box body 4 is running, the heat generated inside is transmitted from the bottom, and the waste heat contained in the waste gas is filtered through the activated carbon filter 22. After the plywood 8 is unfolded, the space below increases, which increases the transmission area of ​​the heat source and the heat dispersion speed, thereby improving the heat dissipation effect.

[0041] Detailed usage and effects of this embodiment:

[0042] A number of heat dissipation vents are provided at the bottom of the box body 4, and the first support ring 5 is fixed to the bottom of the box body 4 to drive the first motor 45 to run. The first motor 45 drives the winding wheel 46 connected above to pay out the line, causing the cable 49 to be loosened and not in a taut state. At the same time, a telescopic movement is generated between the driving cylinder 31 and the gas rod 32, and the gas rod 32 drives the upper sleeve gear 1 33 upward to be on the same horizontal plane with the side gear 2 34 and meshing with the gear 2 34. At this time, the second motor 30 is driven to run, and the second motor 30 drives the cylinder 31 to rotate, and the gas rod 32 will rotate together, further driving the gear 1 33 set above to rotate, and the gear 1 33 will drive the meshing gear 2 34 on the side to rotate. When the gear 2 34 rotates, the winding wheel 4 35 connected to the middle part through the gear shaft When the reel 4 rotates, the cable 39 wound thereon will be wound around it, and at the same time, the cable 39 will pull the reel 38, and then pull the moving block 37 to slide towards the middle on the track plate 36, and the moving block 37 will pull the outer end of the plywood 8 downward through the cable 2 41 to unfold the plywood 8, and the drill rod 13 set at the outer end of the plywood 8 is inserted into the soil or supporting the ground, wherein the first motor 45 and the second motor 30 can drive the connected cables at the same time, so that the cables are in a taut state, that is, when the cable 1 49 is releasing the rope, the cable 2 41 is in a taut state, and after the plywood 8 is unfolded, it is supported by the drill rod 13 around the bottom of the box 4. At this time, there is a certain space between the box 4 and the supporting base 1 and the mounting components, so that multiple compartment spaces are formed under the box 4.

[0043] When the heat generated by the box body 4 is running, it is transmitted, and the exhaust gas contained in the heat passes through the activated carbon filter 22 below for preliminary filtration. The heat penetrates and diffuses around. At this time, the air rod 32 extends into the cylinder 31, and the gear 1 33 will move downward to leave the gear 2 34. The gear 1 33 and the gear 2 34 are disconnected, keeping the plywood 8 in an expanded state. When the air rod 32 is retracted downward, the shaft 20 moves downward, wherein a convex strip is provided on the surface of the shaft 20, and a convex groove matching the convex strip is provided on the inner wall of the cam mechanism 27. The convex strip is embedded in the convex groove. When the shaft 20 moves downward, it slides downward through the cam mechanism 27, and the cam mechanism 27 remains in its original position. At this time, the sound absorbing panel 15 will also be pulled downward, and the spiral column 16 will follow downward, and then the second motor 30 will be driven. During operation, the second motor 30 drives the cylinder 31 to rotate together, and the air rod 32 drives the rotating shaft 20 to rotate. After the rotating shaft 20 rotates, the cam mechanism 27 is rotated due to the cooperation between the surface convex strips and the convex grooves on the inner wall of the cam mechanism 27. Since the piston rod 28 is movably connected to the cam mechanism 27, and the piston rod 28 and the piston plate inside the cylinder body 29 are also movably connected, when the cam mechanism 27 rotates, it will drive the piston rod 28 to move in the cylinder body 29, and the air inside the cylinder body 29 will generate positive and negative pressure, and the holes provided on the cylinder body 29 will dissipate the air power generated inside. At the same time, after the rotating shaft 20 rotates, it drives the upper rotor 24, and a magnetic field effect is generated between the rotor 24 and the stator 23, wherein the magnetic field generator is composed of at least one permanent magnet, or the magnetic field generator is composed of at least one permanent magnet and at least one soft magnet.

[0044] By setting up two magnetocaloric material beds, it can be ensured that the air needs to pass through the magnetocaloric material beds for demagnetization and heat dissipation when flowing, and then provide flow power to the surrounding air under the action of the rotational force generated by the upper fan blades 17. At the same time, after the rotating shaft 20 rotates, the upper fan blades 17 will bring the air flow above, and the cold air generated by the condenser 19 inside the spiral column 16 is emitted through the heat dissipation holes 18, and the surrounding temperature will be affected, thereby dissipating and cooling the diffused heat source. At the same time, the sound-absorbing panel 15 has the effect of absorbing noise. In addition, the generated noise will hit the spiral column 16 during transmission. The surface spiral structure of the spiral column 16 increases the transmission path, so that the noise will be weakened.

[0045] The above specific embodiments will allow those skilled in the art to easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific embodiments. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to implement different technical solutions.
