Description

Technical Field

[0001] The invention relates to the technical field of transformers, and in particular to an adjustable transformer heat dissipation device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Existing transformers generate a lot of heat during operation, causing their temperature to rise continuously during operation. Existing transformers are mainly divided into two types, namely oil-immersed transformers and dry-type transformers. The heat dissipation method of oil-immersed transformers is that the oil and iron core of the transformer dissipate heat through natural convection. After absorbing the heat generated by the windings and the iron core, the density of the transformer oil decreases and flows upward into the oil pillow, while the cooler oil in the oil pillow sinks to replenish. This convection process helps to dissipate heat. In order to enhance the heat dissipation effect, some oil-immersed transformers are equipped with fans. This fan helps increase air flow and take away the heat on the surface of the transformer and in the oil. After searching, it was found that Patents with publication numbers CN111627654A and CN110850946A also disclose heat dissipation structures that have a heat dissipation effect. Although the above-mentioned prior art has a heat dissipation effect, it only achieves the heat dissipation effect by independently using water cooling or air cooling. In addition, in order to improve the heat dissipation effect, the prior art usually installs multiple sets of heat dissipation pipes in the oil tank, and takes away the heat transferred from the transformer oil to the heat dissipation pipes through air circulation. However, during long-term use, the heat dissipation pipes will accumulate too much dust, thereby affecting their heat dissipation efficiency, and the filtering device used to filter dust in the air will also adsorb too much dust impurities, thereby affecting the heat dissipation effect of the air, that is, maintenance personnel are required to regularly clean and unclog the heat dissipation pipes and filtering equipment to keep them working normally.

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited. Example 1

[0026] An adjustable transformer heat dissipation device, such as Figure 1 to Figure 3 As shown, it includes a mounting frame 1, an oil-immersed transformer 2, a connecting frame 3, an oil conservator 4 and a first connecting pipe Ⅰ5; the mounting frame 1 is fixedly connected to the oil-immersed transformer 2; the connecting frame 3 is fixedly connected to the oil conservator 4; the oil conservator 4 is connected to two symmetrically arranged first connecting pipes Ⅰ5; all the first connecting pipes Ⅰ5 are connected to the oil-immersed transformer 2;

[0027] It also includes a water tank 6, a water inlet pipe 7, a delivery pipe 8, a telescopic pipe 9, a filter 10, a second connecting pipe II 11, a heat dissipation pipe 12, a third connecting pipe III 13, an electric push rod 14, a connecting plate 15 and a micro pump 16; the oil-immersed transformer 2 is fixedly connected with a water tank 6; the water tank 6 is connected with a water inlet pipe 7; the water tank 6 is connected with two symmetrically arranged delivery pipes 8; each delivery pipe 8 is connected with a telescopic pipe 9; each telescopic pipe 9 is fixedly connected with a filter 10; the oil-immersed transformer 2 is connected with two symmetrically arranged micro pumps 16; each micro pump 16 is connected with the corresponding delivery pipe 8; each micro pump 16 is connected with a second connecting pipe II 11; the second connecting pipe II 11 runs through the oil-immersed transformer 2, and the second connecting pipe II 11 is connected to the oil A sealing gasket is provided at the connection of the oil-immersed transformer 2; each second connecting pipe II 11 is connected to seven equidistantly distributed heat dissipating pipes 12; the seven heat dissipating pipes 12 located in the front are connected to the third connecting pipe III 13; the seven heat dissipating pipes 12 located in the rear are commonly connected to another third connecting pipe III 13, all the heat dissipating pipes 12 penetrate the oil-immersed transformer 2, and the positions where the heat dissipating pipes 12 contact the oil-immersed transformer 2 are provided with sealing gaskets, and the two heat dissipating pipes 12 located on the far right penetrate the corresponding first connecting pipe I 5 and the oil storage cabinet 4; an electric push rod 14 is passed through the water tank 6, and a sealing gasket is provided at the connection position between the water tank 6 and the electric push rod 14; a connecting plate 15 is fixedly connected to the telescopic end of the electric push rod 14; the connecting plate 15 is fixedly connected to all the filters 10.

[0028] A guide frame is arranged on the upper part of the water tank 6. The guide frame is an expanded opening with a larger upper part and a smaller lower part, so as to collect water discharged from the third connecting pipe III 13.

[0029] The filter screen 10 is provided with a hemispherical structure to increase the filtering area. At the same time, the hemispherical structure cooperates with the water discharged from the third connecting pipe III 13 to wash away the dust attached to the surface.

[0030] First, the staff uses an external water injection device to connect with the water inlet pipe 7. During the operation of the oil-immersed transformer 2, after the oil-immersed transformer 2 has been running for a long time, the temperature of the iron core in the oil-immersed transformer 2 increases, thereby driving the temperature of the cooling oil in the oil-immersed transformer 2 to increase, that is, the density of the cooling oil decreases as the temperature increases, and flows into the oil conservator 4 through the first connecting pipe I5, while the colder cooling oil in the oil conservator 4 sinks and is supplemented into the oil-immersed transformer 2, that is, the oil-immersed transformer 2 is cooled. Since the oil stored in the oil conservator 4 is limited and in a sealed state, its cooling efficiency is limited and cannot meet the required heat dissipation requirements. That is, in the process of heat dissipation of the oil-immersed transformer 2, the micro pump 16 is controlled to operate, and the filter 10, the telescopic tube 9 and The delivery pipe 8 inhales air, causing the air to enter the second connecting pipe II 11 and the heat dissipation pipe 12, and then be discharged through the third connecting pipe III 13, that is, the cooling oil in the oil-immersed transformer 2 is continuously heat-exchanged and cooled by air circulation. In the process of inhaling air through the filter 10, the telescopic pipe 9 and the delivery pipe 8, although the dust can be filtered out by the filter 10, some dust particles still enter the second connecting pipe II 11, the heat dissipation pipe 12 and the third connecting pipe III 13 under the action of the airflow, so that the dust adheres to the inner walls of the second connecting pipe II 11, the heat dissipation pipe 12 and the third connecting pipe III 13. The dust adheres to the second connecting pipe II 11, the heat dissipation pipe 12 and the third connecting pipe III 13, which will affect the air flow and the air and the oil-immersed transformer 2. The cooling oil in the filter 10 is heat exchanged and cooled, and after long-term use, the filter 10 will absorb too much dust, which will affect the air entering the second connecting pipe II 11, the heat dissipation pipe 12 and the third connecting pipe III 13, affecting the air cooling and heat dissipation effect. Therefore, after the air cooling operation has been running for a period of time, the external water injection device is controlled to operate, and water is injected into the water tank 6 through the water inlet pipe 7. When the water is flush with the connecting plate 15, the external water injection device is controlled to stop injecting water, and then the electric push rod 14 is controlled to contract and drive the connecting plate 15 to move downward. The connecting plate 15 drives the filter 10 to move downward and compresses the telescopic pipe 9 to make the filter 10 enter the water in the water tank 6. In this process, the micro pump 16 keeps running. At this time, the air is sucked through the filter 10, the telescopic pipe 9 and the delivery pipe 8. The water enters the water tank 6, so that the water enters the second connecting pipe II 11 and the heat dissipation pipe 12, and then is discharged through the third connecting pipe III 13, that is, the dust attached to the second connecting pipe II 11 and the heat dissipation pipe 12 is cleaned by water to ensure that the cooling oil in the oil-immersed transformer 2 is effectively heat-exchanged and cooled during subsequent air cooling. At the same time, when the water flows in the second connecting pipe II 11 and the heat dissipation pipe 12, the water continues to heat-exchange and cool the cooling oil in the oil-immersed transformer 2, avoiding that when the second connecting pipe II 11, the heat dissipation pipe 12 and the third connecting pipe III 13 are cleaned, the cooling oil in the oil-immersed transformer 2 cannot be heat-exchanged and cooled, and the water discharged from the third connecting pipe III 13 flows back to the water tank 6 again, and the mixed dust in the water is isolated by the filter screen 10 at this time.At the same time, the water discharged from the third connecting pipe III 13 is used to wash the dust adsorbed on the surface of the filter screen 10 due to the air cooling operation. After the second connecting pipe II 11, the heat dissipation pipe 12 and the third connecting pipe III 13 are cleaned by water for multiple cycles, the electric push rod 14 is controlled to push the connecting plate 15 to move upward, so that the connecting plate 15 drives the filter screen 10 to float to the surface of the water, and the telescopic pipe 9 is stretched at the same time, and then the air cooling work is continued by absorbing air. The water flowing back to the water tank 6 has a higher temperature due to multiple cycles. Therefore, during the air cooling operation, the water in the water tank 6 is The water is cooled naturally, and there is no need to use external cooling equipment for cooling, which saves costs. As the air flows in the telescopic tube 9, the water in the water tank 6 can be cooled down, and the cooling speed of the water in the water tank 6 can be accelerated. After the water cooling operation, some water will remain in the second connecting tube II 11 and the heat dissipation tube 12, that is, the water in the second connecting tube II 11 and the heat dissipation tube 12 will be vaporized under the influence of the heat generated during the operation of the oil-immersed transformer 2, and the water vaporization is a heat absorption process, that is, the residual water vaporization and the air can improve the heat dissipation effect.

[0031] During the heat dissipation process of air cooling and water cooling, the two heat dissipation pipes 12 on the far right pass through the oil conservator 4 and the first connecting pipe Ⅰ5, that is, the air and water flowing in the two heat dissipation pipes 12 on the right will cool down the cooling oil in the oil conservator 4 and the first connecting pipe Ⅰ5, so that the cooling oil in the oil conservator 4 is replaced with the cooling oil in the oil-immersed transformer 2 after being cooled.

[0032] In addition, a temperature sensor may be provided in the oil-immersed transformer 2, so that when the temperature in the oil-immersed transformer 2 rises abnormally, the temperature sensor controls the electric push rod 14 to drive the filter 10 into the water in the water tank 6 to directly perform water cooling operation, and the water cooling operation is adjusted to provide a stronger heat dissipation effect for the oil-immersed transformer 2. It should be noted that the specific heat capacity of water is greater than that of air, so the water cooling heat dissipation effect is better. If after adjusting to the water cooling operation, the temperature sensor detects that the temperature in the oil-immersed transformer 2 is still abnormally heated, then the temperature sensor sends a signal to control the oil-immersed transformer 2 to stop running, and sends the abnormal signal to the staff. Example 2

[0033] On the basis of the above-mentioned embodiment 1, Figure 4-5As shown, it also includes an adsorption component, which includes a sponge tube 101, a connecting shaft 102, an extrusion plate 103 and a DD motor 104; each second connecting tube Ⅱ11 is fixedly connected to a sponge tube 101; each second connecting tube Ⅱ11 is rotatably connected to a connecting shaft 102, and the connecting shaft 102 passes through the second connecting tube Ⅱ11 and the outer shell of the oil-immersed transformer 2 respectively; the connecting shaft 102 is rotatably connected to the oil-immersed transformer 2; each connecting shaft 102 is fixedly connected to an extrusion plate 103, the extrusion plate 103 is located in the sponge tube 101, and the extrusion plate 103 is in contact with the sponge tube 101; two symmetrically arranged DD motors 104 are bolted to the oil-immersed transformer 2; the output shaft of each DD motor 104 is fixedly connected to the corresponding connecting shaft 102.

[0034] The connection points between the connecting shaft 102, the oil-immersed transformer 2 and the second connecting pipe II 11 are all provided with rubber rings to ensure the sealing effect and avoid leakage.

[0035] An arc-shaped scraper is provided on the squeezing plate 103 to facilitate cleaning of dust adsorbed on the sponge tube 101 .

[0036] During the air-cooling heat dissipation process, after the air flows into the second connecting tube Ⅱ11 and the heat dissipation tube 12, since the heat dissipation tube 12 bears the main heat exchange and cooling effect, a sponge tube 101 is set in the second connecting tube Ⅱ11, that is, during the air-cooling process, the sponge tube 101 absorbs and intercepts the dust in the air entering the heat dissipation tube 12 from the second connecting tube Ⅱ11, so as to reduce the dust attached to the heat dissipation tube 12 after the air enters the heat dissipation tube 12, so as to extend the service life of the heat dissipation tube 12, reduce the frequency of cleaning the heat dissipation tube 12, and allow the water in the water tank 6 to have sufficient time to cool down. Although the porous structure of the sponge tube 101 can absorb a large amount of dust, dust will still adhere to the heat dissipation tube 12 after long-term use. At the same time, after the dust adsorbed on the surface of the sponge tube 101 is saturated, the dust will still adhere to the inner wall of the heat dissipation tube 12 in large quantities. Therefore, when switching to the water-cooling mode to clean the second connecting tube Ⅱ11 and the heat dissipation tube 12, the DD motor 104 is controlled to drive the connecting shaft 102 to rotate, and the connecting shaft 102 The squeezing plate 103 is driven to rotate, and the squeezing plate 103 is used to scrape the dust attached to the surface of the sponge tube 101 due to air cooling, so that the sponge tube 101 is cleaned with water. After the second connecting tube Ⅱ 11 and the heat dissipation tube 12 are cleaned by water cooling, a large amount of water will be adsorbed on the sponge tube 101, thereby enhancing the adsorption effect of dust in the air during the subsequent air cooling process, further reducing the amount of dust adhering to the inner wall of the heat dissipation tube 12, and further extending the service life of the heat dissipation tube 12. At the same time, after the sponge tube 101 adsorbs water, in the subsequent air cooling process, the heat generated by the oil-immersed transformer 2 will vaporize the water adsorbed in the sponge tube 101, that is, in this process, the vaporized water vapor is mixed with the input air, that is, the water vapor is mixed with the dust in the air, so that the mixture of water vapor and dust is attached to the sponge tube 101, further reducing the dust entering the heat dissipation tube 12, and at the same time, the water adsorbed in the sponge tube 101 can take away the heat transferred to the second connecting tube Ⅱ 11 by the oil-immersed transformer 2 during the vaporization process. Example 3

[0037] Based on the above embodiment 2, Figure 6-7 As shown, it also includes a filtering component, which includes a first filter plate I201, a second filter plate II202 and a waste box 203; the first filter plate I201 is fixedly connected to the connecting plate 15; the first filter plate I201 is fixedly connected to the filter screen 10; the first filter plate I201 is in contact with the inner wall of the water tank 6; the second filter plate II202 is fixedly connected to the inside of the water tank 6; four equidistantly distributed waste boxes 203 are connected to the water tank 6.

[0038] A plurality of protrusions corresponding to the filter holes of the second filter plate II 202 are arranged below the first filter plate I 201 for blocking the filter holes of the second filter plate II 202 .

[0039] The filter holes on the second filter plate II 202 are arranged in a structure that is larger at the top and smaller at the bottom, and are used to limit the dust and impurities in the waste box 203 and reduce the dust and impurities from flowing into the water tank 6 through the filter holes on the second filter plate II 202 .

[0040] The water tank 6 and the waste box 203 are arranged in a quick-release structure for cleaning dust and impurities in the waste box 203 .

[0041] During the air cooling process, the water in the water tank 6 is in a static state, that is, after a long period of precipitation, the dust and impurities in the water will flow downward through the second filter plate II 202 and enter the waste box 203. Since the water in the water tank 6 is in a static state, part of the dust and impurities in the water in the water tank 6 are removed by precipitation and stored in the waste box 203. When the water cooling is performed, the electric push rod 14 is controlled to contract and drive the connecting plate 15 to the lower end, and the connecting plate 15 drives the first filter plate I 201 to the lower end to approach and fit the second filter plate II 202, that is, the filter holes on the second filter plate II 202 are blocked by the protrusions on the lower surface of the first filter plate I 201, and the water tank 6 and the waste box 203 are separated by the first filter plate I 201 and the second filter plate II 202, that is, the dust and impurities in the waste box 203 are prevented from being sucked into the delivery pipe 8 and the telescopic pipe 9 with the water flow, and then enter the second connecting pipe II 11 and the heat dissipation pipe 12, that is, the impurities in the water during the water cooling process are reduced.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
