Description

Technical Field

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

[0002] A dry-type power transformer is a dry-type transformer with very high electrical strength, mechanical strength, and heat resistance. It is an excellent product for urban power grid transformation and is especially suitable for important places such as high-rise buildings, airports, power stations, and commercial centers that require fire prevention, explosion prevention, and moisture protection. Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports, docks, and CNC machinery equipment. Simply put, a dry-type transformer refers to a transformer in which the iron core and winding are not impregnated in insulating oil. The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When natural air cooling is used, the transformer can operate continuously for a long time at the rated capacity. When forced air cooling is used, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation or emergency accident overload operation; since the load loss and impedance voltage increase significantly during overload, it is in a non-economic operation state, so it should not be operated under long-term continuous overload.

[0003] With the development of China's national economy, the continuous improvement of national environmental protection regulations, and the enhancement of people's environmental protection awareness. The share of dry-type transformers in urban distribution transformers has accelerated, and at the same time, users' requirements for dry-type transformer manufacturers are also getting higher and higher.

An interlayer space will be formed between the first support ring 5 and the second support ring 6. The top of the first support ring 5 is fixed to the bottom of the box body 4. The bottom of the box body 4 is provided with a heat dissipation port. After the box body 4 operates, the heat generated inside is transmitted from the bottom. The waste heat contains waste gas that is filtered through the activated carbon filter screen 22. After the heat source expands with the plywood 8, with the increase of the space below, the transmission area of the heat source increases, and the heat dissipation speed increases, thereby improving the heat dissipation effect.

[0041] Detailed usage method and function of this embodiment:

[0042] A number of heat dissipation ports are provided at the bottom of the box body 4. The first support ring 5 is fixed to the bottom of the box body 4. The first motor 45 is driven to operate. The first motor 45 drives the wire winding wheel one 46 connected above to pay out the wire, so that the cable one 49 is loosened and not in a taut state. At the same time, telescopic movement is generated between the driving cylinder 31 and the air rod 32. The air rod 32 drives the gear one 33 sleeved on the upper part to move up to the same horizontal plane as the side gear two 34 and mesh with the gear two 34. At this time, the second motor 30 is driven to operate. The second motor 30 drives the cylinder 31 to rotate, and the air rod 32 will rotate along with it, further driving the gear one 33 sleeved on the upper part to rotate. The gear one 33 will drive the side meshing gear two 34 to rotate. When the gear two 34 rotates, the wire winding wheel four 35 connected by the gear shaft in the middle rotates. After the wire winding wheel four 35 rotates, the cable three 39 wound on it will be wound on it. At the same time, the cable three 39 will pull the wire winding wheel three 38, and then pull the moving block 37 to slide towards the middle on the track plate 36. The moving block 37 pulls the outer end of the plywood 8 downward through the cable two 41 to unfold the plywood 8. The drill rod 13 provided at the outer end of the outer side of the plywood 8 is inserted into the soil or supports the ground. Among them, the first motor 45 and the second motor 30 can drive the connected cables at the same time to make the cables in a taut state. That is to say, when the cable one 49 pays out the rope, the cable two 41 is in a taut state. After the plywood 8 is unfolded, it is supported by the drill rod 13 around the lower part of the box body 4. At this time, there is a certain space interlayer between the box body 4, the support chassis 1 and the installation components, so that multiple interlayer spaces will be formed below the box body 4.

[0043] When the heat generated by the box body 4 is running, the exhaust gas contained in the heat passes through the activated carbon filter 22 below for preliminary filtration, and the heat penetrates and diffuses around. At this time, the gas rod 32 extends into the cylinder 31, and the gear 1 33 will move downward to leave the gear 2 34, and the gear 1 33 and the gear 2 34 are disconnected, keeping the clamping plate 8 in an expanded state. When the gas 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, and 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 it downward, and then drive the second motor 30. 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, due to the cooperation between the surface convex strip and the convex groove on the inner wall of the cam mechanism 27, the cam mechanism 27 is rotated. 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 pressures, 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 with the rotational force generated by the upper fan blades 17, the surrounding air is provided with flow power. At the same time, after the rotating shaft 20 rotates, the upper fan blades 17 will bring the upper air flow, and the cold air generated by the condenser 19 inside the spiral column 16 is emitted through the heat dissipation holes 18, 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] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
