Description

Technical Field

[0001] This invention relates to the field of power transformers, and more specifically, to a device for monitoring the temperature status of dry-type transformers. Background Technology

[0002] Traditional dry-type transformers primarily rely on natural heat dissipation or simple air cooling for heat dissipation. Natural heat dissipation depends mainly on the natural convection between the transformer surface and the surrounding air for heat exchange, which is inefficient and difficult to meet the heat dissipation requirements of transformers under high load or high temperature environments. When a transformer operates under high load for extended periods, the heat generated inside cannot be dissipated in time, leading to a rapid increase in transformer temperature, accelerated aging of insulation materials, shortened transformer lifespan, and potentially even transformer failure, causing power outages and resulting in significant losses to the power system and users.

[0003] While simple air-cooling improves heat dissipation efficiency to some extent, it still has many shortcomings. Air-cooling typically involves installing fans around the transformer, using the airflow to remove heat from the transformer's surface. However, these fans are usually stationary and cannot intelligently adjust based on the transformer's actual temperature. When the transformer temperature is low, the fan continues to run, wasting energy and generating unnecessary noise; conversely, when the transformer temperature is high, the fan's cooling capacity may be insufficient, causing the transformer temperature to rise further and affecting its normal operation.

[0004] To address the aforementioned problems, this invention proposes a dry-type transformer temperature status monitoring device. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the present invention aims to provide a dry-type transformer temperature status monitoring device. This solution, through the coordinated use of data processing and temperature and power acquisition modules, can comprehensively and accurately monitor the transformer's operating status in real time, promptly identifying potential problems. The intelligent temperature control module intelligently adjusts the circulating pump based on temperature feedback to achieve precise heat dissipation, avoid overheating damage, extend lifespan, and ensure stable operation of the power system. The heat-conducting plate and fan work together to form an efficient heat exchange network. When the transformer experiences localized overheating, the heat pipe assembly automatically slides towards the high-temperature area to achieve targeted and enhanced heat dissipation. The human-machine interface module is easy to operate, the heat-conducting plate is easy to install and disassemble, the sliding groove design allows the heat pipe heat dissipation assembly to slide smoothly, and the magnetic shielding powder and magnet blocks work together to enhance thrust, improve heat dissipation efficiency, and reduce energy consumption.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A dry-type transformer temperature status monitoring device includes a monitoring box body, within which a dry-type transformer and a monitoring unit are housed. The monitoring unit includes a data processing module, a temperature acquisition module, and a power acquisition module. An intelligent temperature control module is located at the right end of the monitoring box body. This intelligent temperature control module includes an exchange pipe, the outer end of which is connected to a storage tank. A circulation pump is installed at the outer end of the storage tank, and the circulation pump is electrically connected to the temperature acquisition module. Through the coordinated operation of the temperature acquisition module, the power acquisition module, and the data processing module, this dry-type transformer temperature status monitoring device can achieve comprehensive monitoring of the transformer's operating status. The high-precision measurement of the temperature acquisition module, through real-time and accurate monitoring, can promptly detect potential problems such as local overheating of the transformer. The accurate acquisition of power data by the power acquisition module helps to assess the transformer's load status and power quality. The data processing module performs in-depth analysis of this data, providing a scientific and reasonable basis for the intelligent temperature control module. Based on the feedback signal from the temperature acquisition module, the intelligent temperature control module achieves precise regulation of the transformer temperature through intelligent control of the circulating pump. This combination of precise monitoring and intelligent regulation can effectively prevent transformer damage due to overheating, extend the transformer's service life, and ensure the stable operation of the power system.

[0010] Furthermore, the exchange pipe is equipped with multiple first heat-conducting plates and second heat-conducting plates, which are spaced apart. The first heat-conducting plate has a first vent hole at its outer end, and a fan is installed in the first vent hole. The second heat-conducting plate has a second vent hole at its outer end. The first and second heat-conducting plates are spaced apart in the exchange pipe. This layout is like a carefully woven "heat exchange network". When the cooling medium flows in the exchange pipe, the first and second heat-conducting plates can greatly increase the heat transfer effect of the cooling medium. The heat-conducting plates are usually made of materials with high thermal conductivity, such as aluminum alloy, which can quickly conduct the heat generated by the dry transformer to the cooling medium. After the fan is started, it can generate a strong airflow. The airflow forms a directional flow in the exchange pipe through the first vent hole.

[0011] On the one hand, the airflow directly blows on the surface of the first heat-conducting plate, accelerating the airflow speed on the surface of the heat-conducting plate. According to the principle of thermal convection, the faster the airflow speed, the stronger the ability to carry away heat. Therefore, the airflow generated by the fan can quickly carry away the heat on the first heat-conducting plate, reduce the temperature of the heat-conducting plate, and thus improve the heat exchange efficiency between the heat-conducting plate and the cooling medium.

[0012] On the other hand, when the airflow flows in the exchange pipe, it also disturbs the surrounding air, forming a turbulence effect. Turbulence can disrupt the air boundary layer, increase the contact opportunities between the air and the heat conduction plate and the cooling medium, and further enhance the heat convection heat dissipation effect. At the same time, the airflow can also promote the renewal of the air in the exchange pipe, exhaust the hot air that has absorbed heat from the pipe, and introduce fresh cold air, forming a good heat dissipation cycle.

[0013] Furthermore, two symmetrical grooves are carved into the outer end of the second heat-conducting plate. A heat pipe heat dissipation assembly is slidably connected within the grooves. The heat pipe heat dissipation assembly includes a slider located within the groove. Two rollers are rotatably connected to both the upper and lower ends of the slider. A heat pipe located inside the monitoring box body is connected to the outer end of the slider. Two symmetrical deformation airbags are connected to the outer end of the slider and are located within the grooves. When the dry-type transformer generates heat during operation, the temperature of the end of the heat pipe near the transformer rises rapidly. The heat transfer medium inside the heat pipe absorbs heat and then... During a phase change, the heat transfer medium changes from a liquid to a gaseous state. Under the influence of a small pressure difference inside the heat pipe, the gaseous heat transfer medium rapidly flows to the other end of the heat pipe. At the cold end, the gaseous heat transfer medium releases heat to the surrounding air or other cooling media, and then condenses back into a liquid state. Subsequently, the liquid heat transfer medium flows back to the hot end under the capillary action of the inner wall of the heat pipe to continue absorbing heat. This cycle repeats continuously, achieving efficient heat transfer and dissipation. This efficient heat dissipation characteristic of the heat pipe can quickly remove the heat generated by the dry-type transformer and reduce the transformer temperature.

[0014] Furthermore, the heat pipe is made of aluminum alloy with high thermal conductivity and is filled with a heat transfer medium. The inner wall of the heat pipe is roughened. When the temperature of the hot end of the heat pipe rises, the heat transfer medium inside the heat pipe absorbs heat and vaporizes. The vapor flows rapidly to the cold end of the heat pipe, releases heat at the cold end, condenses into liquid, and then flows back to the hot end through capillary action. This cycle repeats continuously to achieve efficient heat transfer.

[0015] Furthermore, a magnet is connected between the upper and lower inner walls of the deformable airbag, and multiple uniformly distributed magnetic shielding powders are provided inside the deformable airbag.

[0016] Furthermore, a human-machine interaction module is installed on the outer end of the main body of the monitoring box, and the human-machine interaction module is connected to the data processing module.

[0017] Furthermore, both the first and second heat-conducting plates are equipped with handles at their outer ends, which facilitates the installation and disassembly of the first and second heat-conducting plates by technicians.

[0018] Furthermore, the cross-section of the slide groove is convex, and a polished layer is provided at the contact points between the slide groove and the slider. By making the slide groove convex, the entire heat pipe heat dissipation assembly is less likely to separate from the slide groove. By providing a polished layer, the heat pipe heat dissipation assembly can slide more smoothly within the slide groove.

[0019] Furthermore, the two magnets that are close to each other repel each other. By setting the magnets that are close to each other to repel each other, the heat pipe heat dissipation assembly can be driven to slide laterally in the groove under the repulsive action of the magnets after the deformation airbag expands, thereby improving the heat dissipation efficiency of the heat pipe in the main body of the monitoring box.

[0020] Furthermore, the magnetic shielding powder is made of an iron-nickel alloy material, with a nickel content of 80%. By using an iron-nickel alloy to make the magnetic shielding powder, the gaps between adjacent magnetic shielding powders are smaller when the deformation airbag contracts, thus providing magnetic shielding for the magnet. When the deformation airbag expands, the gaps between the magnetic shielding powders increase, thereby removing the shielding effect on the magnet. Under normal conditions, the magnetic shielding powder provides magnetic shielding for the magnet, resulting in a smaller repulsive force between two magnets that are close to each other. When the deformation airbag expands due to heat, the gaps between adjacent magnetic shielding powders gradually increase, and the original magnetic shielding effect gradually dissipates. As the magnetic shielding effect weakens, the repulsive force between two magnets that are close to each other gradually increases, further enhancing the thrust of the deformation airbag on the slider and prompting the heat pipe cooling assembly to move to the appropriate position more quickly.

[0021] 3. Beneficial Effects

[0022] Compared with the prior art, the advantages of this invention are:

[0023] This solution, through the collaborative efforts of data processing, temperature, and power acquisition modules, enables comprehensive, real-time, and accurate monitoring of the transformer's operating status, promptly identifying potential problems. The intelligent temperature control module, based on temperature feedback, intelligently adjusts the circulating pump to achieve precise heat dissipation, preventing overheating damage, extending lifespan, and ensuring stable power system operation. The heat-conducting plate and fan work together to form a highly efficient heat exchange network. When the transformer experiences localized overheating, the heat pipe assembly automatically slides towards the high-temperature area for targeted and enhanced heat dissipation. The human-machine interface module is easy to operate, the heat-conducting plate is convenient to install and remove, the sliding groove design allows for smooth sliding of the heat pipe cooling assembly, and the combination of magnetic shielding powder and magnets enhances thrust, improving heat dissipation efficiency and reducing energy consumption.

[0036] Example 1:

[0037] Please see Figure 1-3 A dry-type transformer temperature status monitoring device includes a monitoring box body 1, within which a dry-type transformer 2 and a monitoring unit are installed. The monitoring unit includes a data processing module 3, a temperature acquisition module 4, and a power acquisition module 5. An intelligent temperature control module 6 is located at the right end of the monitoring box body 1. The intelligent temperature control module 6 includes an exchange pipe 7, with a storage tank 8 connected to its outer end. A circulation pump 9 is installed at the outer end of the storage tank 8 and is electrically connected to the temperature acquisition module 4. Through the coordinated operation of the temperature acquisition module 4, the power acquisition module 5, and the data processing module 3, this dry-type transformer temperature status monitoring device can achieve comprehensive monitoring of the transformer's operating status. Real-time and accurate monitoring: The high-precision measurement of the temperature acquisition module 4 can promptly detect potential problems such as local overheating of the transformer. The accurate acquisition of power data by the power acquisition module 5 helps to assess the load status and power quality of the transformer. The data processing module 3 performs in-depth analysis of these data to provide a scientific and reasonable basis for regulation and control for the intelligent temperature control module 6. Based on the feedback signal from the temperature acquisition module 4, the intelligent temperature control module 6 achieves precise regulation and control of the transformer temperature through the intelligent control of the circulating pump 9. This combination of precise monitoring and intelligent regulation can effectively prevent the transformer from being damaged due to overheating, extend the service life of the transformer, and ensure the stable operation of the power system.

[0038] In this system, the exchange pipe 7, storage tank 8, and circulating pump 9 in the intelligent temperature control module 6 work together to form a highly efficient heat dissipation system. The rational design of the exchange pipe 7 ensures sufficient heat exchange between the cooling medium and the transformer, improving heat dissipation efficiency. The storage tank 8 can stably provide the cooling medium, ensuring the continuous operation of the heat dissipation system. The intelligent control of the circulating pump 9 adjusts its working state according to the actual temperature of the transformer, avoiding unnecessary energy waste. Compared with traditional transformer heat dissipation methods, this online controller can more accurately control the heat dissipation process, meeting the transformer's heat dissipation needs while minimizing energy consumption and improving energy utilization efficiency.

[0039] Please see Figure 3-4The heat exchange pipe 7 is equipped with multiple first heat-conducting plates 10 and second heat-conducting plates 11, which are spaced apart. The outer end of the first heat-conducting plate 10 is drilled with a first vent hole 12, and a fan 13 is installed in the first vent hole 12. The outer end of the second heat-conducting plate 11 is drilled with a second vent hole 14. The first heat-conducting plates 10 and second heat-conducting plates 11 are spaced apart in the heat exchange pipe 7. This layout is like a carefully woven "heat exchange network". When the cooling medium flows in the heat exchange pipe 7, the first heat-conducting plates 10 and second heat-conducting plates 11 can greatly increase the heat transfer effect of the cooling medium. The heat-conducting plates are usually made of materials with high thermal conductivity, such as aluminum alloy, which can quickly conduct the heat generated by the dry transformer to the cooling medium. After the fan 13 is started, it can generate a strong airflow. The airflow forms a directional flow in the heat exchange pipe 7 through the first vent hole 12.

[0040] On the one hand, the airflow directly blows on the surface of the first heat-conducting plate 10, accelerating the airflow speed on the surface of the heat-conducting plate. According to the principle of heat convection, the faster the airflow speed, the stronger the ability to carry away heat. Therefore, the airflow generated by the fan 13 can quickly carry away the heat on the first heat-conducting plate 10, reduce the temperature of the heat-conducting plate, and thus improve the heat exchange efficiency between the heat-conducting plate and the cooling medium.

[0041] On the other hand, when the airflow flows in the exchange pipe 7, it will also disturb the surrounding air and form a turbulence effect. Turbulence can destroy the air boundary layer, increase the contact opportunities between the air and the heat conduction plate and the cooling medium, and further enhance the heat convection heat dissipation effect. At the same time, the airflow can also promote the renewal of the air in the exchange pipe 7, exhaust the hot air that has absorbed heat from the pipe, and introduce fresh cold air to form a good heat dissipation cycle.

[0042] Please see Figure 5The second heat-conducting plate 11 has two symmetrical grooves 15 cut into its outer end. A heat pipe heat dissipation assembly 16 is slidably connected in the grooves 15. The heat pipe heat dissipation assembly 16 includes a slider 17 located in the groove 15. Two rollers 18 are rotatably connected to both the upper and lower ends of the slider 17. A heat pipe 19 located in the main body 1 of the monitoring box is connected to the outer end of the slider 17. Two symmetrical deformation airbags 20 are connected to the outer end of the slider 17. The deformation airbags 20 are located in the grooves 15. Inside, when the dry-type transformer generates heat during operation, the temperature of the hot end of the heat pipe 19, which is close to the transformer, rises rapidly. The heat transfer medium 21 inside the heat pipe 19 absorbs heat and undergoes a phase change, changing from a liquid to a gaseous state. Under the influence of a small pressure difference inside the heat pipe 19, the gaseous heat transfer medium 21 quickly flows to the cold end of the heat pipe 19. At the cold end, the gaseous heat transfer medium 21 releases heat to the surrounding air or other cooling media, and then condenses back into a liquid state. Subsequently, the liquid heat transfer medium 21 flows back to the hot end under the capillary action of the inner wall of the heat pipe 19 to continue absorbing heat. This cycle repeats, achieving efficient heat transfer and dissipation. This efficient heat dissipation characteristic of the heat pipe 19 can quickly remove the heat generated by the dry-type transformer and reduce the transformer temperature.

[0043] Please see Figure 6-7 The heat pipe 19 is made of aluminum alloy with high thermal conductivity. The heat pipe 19 is filled with heat transfer medium 21. The inner wall of the heat pipe 19 is rough. When the temperature of the hot end of the heat pipe 19 rises, the heat transfer medium 21 inside the heat pipe absorbs heat and vaporizes. The vapor flows rapidly to the cold end of the heat pipe 19. After releasing heat at the cold end, it condenses into liquid and then flows back to the hot end through capillary action. This cycle repeats to achieve efficient heat transfer. A magnet block 22 is connected between the upper and lower inner walls of the deformable airbag 20. The deformable airbag 20 is provided with multiple uniformly distributed magnetic shielding powders 23.

[0044] Please see Figure 1-4 A human-machine interaction module 101 is installed on the outer end of the main body 1 of the monitoring box, and the human-machine interaction module 101 is connected to the data processing module 3.

[0045] Furthermore, handles 1001 are connected to the outer ends of the first heat-conducting plate 10 and the second heat-conducting plate 11. By setting handles 1001, technicians can easily install and disassemble the first heat-conducting plate 10 and the second heat-conducting plate 11. The cross-section of the slide groove 15 is set to be convex. A polished layer is provided at the contact points between the slide groove 15 and the slider 17. By setting the slide groove 15 to be convex, the entire heat pipe heat dissipation assembly 16 is less likely to separate from the slide groove 15. By setting a polished layer, the heat pipe heat dissipation assembly 16 can slide more smoothly in the slide groove 15.

[0046] Please see Figure 7Two magnet blocks 22 that are close to each other repel each other. By setting the magnet blocks 22 that are close to each other to repel each other, the heat pipe heat dissipation component 16 can be driven to slide laterally in the slide groove 15 under the repulsive action of the magnet blocks 22 after the deformation airbag 20 expands. This improves the heat dissipation efficiency of the heat pipe 19 in the monitoring box body 1. The magnetic shielding powder 23 is made of iron-nickel alloy material, and the nickel content in the magnetic shielding powder 23 is 80%. By using iron-nickel alloy to make the magnetic shielding powder 23, the gap between adjacent magnetic shielding powders 23 is smaller when the deformation airbag 20 contracts, so as to magnetically shield the magnet blocks 22. When the deformation airbag 20 expands, the magnetic shielding powder 23 can be magnetically shielded. After the airbag 20 expands, the gaps between the magnetic shielding powders 23 increase, thereby removing the shielding effect on the magnet block 22. Under normal conditions, the magnetic shielding powders 23 provide a magnetic shielding effect on the magnet block 22, resulting in a smaller repulsive force between two magnet blocks 22 that are close to each other. When the deformable airbag 20 expands due to heat, the gaps between adjacent magnetic shielding powders 23 gradually increase, and the original magnetic shielding effect gradually disappears. As the magnetic shielding effect weakens, the repulsive force between two magnet blocks 22 that are close to each other gradually increases, further enhancing the pushing force of the deformable airbag 20 on the slider 17, and prompting the heat pipe heat dissipation assembly 16 to move to the appropriate position more quickly.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
