Description

Technical Field

[0001] The present invention relates to the technical field of transformer protection, and in particular to a novel heat dissipation structure for a transformer. Background Art

[0002] Transformers are core components of power systems, and their heat dissipation performance directly impacts their operating efficiency and lifespan. To prevent dust and debris from clogging the heat dissipation channels, dust shields are typically installed on the outside of transformer radiators to reduce dust intrusion into the fins. However, over time, dust accumulates on these shields, obstructing airflow, reducing heat dissipation efficiency, and even causing transformer overheating.

[0003] At present, the common cleaning methods of dustproof panels mainly include:

[0004] 1. Manual disassembly and cleaning: Remove the dust shield regularly for flushing or wiping, but the operation is cumbersome and requires power outage for maintenance, affecting the continuity of power supply.

[0005] 2. Simple scraping: Use a scraper or brush to clean the surface dust, but it is difficult to completely remove fine particles and manual intervention is still required.

[0006] These traditional methods suffer from low efficiency, manual labor dependency, and long maintenance cycles. Especially in high-dust environments, dust shields may require frequent cleaning, increasing operational costs and safety risks. Therefore, an automatic, efficient, and maintenance-free dust shield cleaning technology is urgently needed to improve transformer heat dissipation performance and operational reliability.

[0007] To this end, a new heat dissipation structure for transformers is proposed, which can automatically trigger the cleaning mechanism when dust accumulates without manual intervention, and significantly improve the cleaning efficiency, thereby optimizing the heat dissipation management of the transformer.

[0012] Preferably, a blowing shaft is provided in the heat dissipation box, and the blowing shaft is a driving source that can drive the flow fan to rotate.

[0014] Preferably, a conversion shaft is provided on the front side of the cleaning water tank, a conversion block is fixedly connected to the conversion shaft, and a wind speed sensor is provided on the rear side of the guide frame, the wind speed sensor is used to measure the flow rate of the air in the guide frame, and the wind speed sensor can also control the conversion shaft;

[0015] The conversion block is rotatably connected to two rotationally symmetrical flip shafts, the flip shafts are fixedly connected to a cleaning gear, and the flip shafts are also fixedly connected to a flip rod, and the two flip rods are respectively fixedly connected to the first dustproof plate and the second dustproof plate;

[0016] The cleaning water tank is also slidably connected with a pushing rack, the pushing rack is connected to a pushing rod, the pushing rod is fixedly connected to a sliding frame, the pushing ring is fixedly connected to a pushing shaft, the outer wall of the pushing shaft is slidably connected to the inner wall of the sliding frame, and the rotation of the stirring shaft can drive the pushing rack to move back and forth.

[0033] The following will refer to the attached Figures 1 to 8 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0034] Example 1

[0035] Refer to the attached Figure 1 -Attached Figure 8 A novel heat dissipation structure for a transformer includes a transformer body 1 and a heat dissipation box 3. The transformer body 1 is arranged in the heat dissipation box 3, and a guide cover 2 is provided on the outside of the transformer body 1 to block water vapor in the flowing air. Figure 8 The air can flow around the air guide cover 2, and the heat transferred in the air through the air guide cover 2 when the transformer body 1 is working can also be quickly taken away by the flowing air.

[0036] The transformer body 1 is surrounded by a condensation pipe 8, and the condensed water in the condensation pipe 8 flows from the rear side to the front side. The condensation pipe 8 and the condensed water can remove part of the heat of the transformer body 1 during operation by contact heat dissipation, which is a conventional method.

[0037] Refer to the attached Figure 1 , the heat dissipation box 3 is provided with an air inlet 4 and an air outlet 5 on opposite sides, the air inlet 4 is on the front side of the device, and the air outlet 5 is on the rear side of the device. The direction of air flow in the heat dissipation box 3 is from the air inlet 4 to the air outlet 5;

[0038] Refer to the attached Figure 7 A plurality of heat outlets 27 are provided on the side of the air guide cover 2 opposite to the air outlet 5. The heat outlets 27 are arranged on the rear side of the air guide cover 2 to prevent water vapor from contacting the transformer body 1 when air circulates. Although the airflow direction passes through this place, it will not flow into the air guide cover 2.

[0039] A sealing block 28 is provided on the inner side of the heat outlet 27, and an airbag 29 is provided inside the air deflector 2. A push rod 30 is provided in contact with the expansion direction of the airbag 29. The sliding direction of the push rod 30 is the same as the sliding direction of the sealing block 28. The expansion of the airbag 29 is controlled by the temperature of the transformer body 1, thereby controlling the opening and closing of the heat outlet 27. When the transformer body 1 generates heat during operation, the heat causes the airbag 29 to expand, driving the push rod 30 to move upward, thereby causing the sealing block 28 to move upward, opening the heat outlet 27 and facilitating the dissipation of heat from the transformer body 1.

[0040] Example 2

[0041] A flow fan 12 is provided at both the air inlet 4 and the air outlet 5. The two flow fans 12 can accelerate the circulation of air in the heat dissipation box 3. A blowing shaft 11 is provided in the heat dissipation box 3. The blowing shaft 11 is a driving source that can drive the flow fan 12 to rotate.

[0042] The outer wall of the air inlet 4 is provided with a guide frame 6 and a cleaning water tank 7. Figure 2 After passing through the transformer body 1, the condensed water flowing in the condensation duct 8 flows through the clean water tank 7 and is then discharged. A first dust shield 10 and a second dust shield 15 are installed within the guide frame 6. As air passes through the guide frame 6, impurities in the air are filtered out by the first dust shield 10 or the second dust shield 15. A cleaning mechanism is installed within the clean water tank 7 to clean dust from the first dust shield 10 and the second dust shield 15.

[0043] The cleaning mechanism includes an agitating shaft 13 disposed within the cleaning water tank 7. The tail end of the condensation pipe 8 communicates with the inner side of the cleaning water tank 7, through which condensed water flows. The agitating shaft 13 is provided with a plurality of agitating blades 14 for agitating the condensed water. The top end of the agitating shaft 13 is provided with a pushing ring 26. The agitated water improves the efficiency of removing impurities from the dustproof plate when the dustproof plate enters the condensed water.

[0044] A conversion shaft 17 is provided on the front side of the cleaning water tank 7, and a conversion block 16 is fixedly connected to the conversion shaft 17. A wind speed sensor 18 is provided on the rear side of the guide frame 6. The wind speed sensor 18 is used to measure the flow rate of the air in the guide frame 6. The wind speed sensor 18 can also control the conversion shaft 17;

[0045] The following is a preferred method for detecting the degree of impurity accumulation. Specifically, when excessive impurities accumulate on the dust shield, obstructing air flow into the guide frame 6, the wind speed sensor 18 monitors the wind speed. When the wind speed is low, it drives the shift shaft 17 to rotate 180 degrees, causing the dust shield, which is heavily laden with dust, to face inward from the guide frame 6. To prevent large amounts of dust from entering the heat sink 3 during this period, the flow fan 12 stops, reducing air circulation. The flow fan 12 only turns on when the dust shield, laden with impurities, rotates inward.

[0046] The conversion block 16 is rotatably connected to two rotationally symmetrical flip shafts 19, and the flip shaft 19 is fixedly connected to a cleaning gear 20. The flip shaft 19 is also fixedly connected to a flip rod 21, and the two flip rods 21 are respectively fixedly connected to the first dustproof plate 10 and the second dustproof plate 15;

[0047] A pushing rack 22 is also slidably connected in the cleaning water tank 7, and a pushing rod 23 is connected to the pushing rack 22. A sliding frame 24 is fixedly connected to the pushing rod 23, and a pushing shaft 25 is fixedly connected to the pushing ring 26. The outer wall of the pushing shaft 25 is slidably connected to the inner wall of the sliding frame 24. The rotation of the stirring shaft 13 can drive the pushing rack 22 to move back and forth.

[0048] The forward and backward movement of the pushing rack 22 can drive the flip rod 21 to rotate 90 degrees. When the flip rod 21 rotates to the lowest point, it can contact the discharged condensed water.

[0049] Refer to the attached Figure 4 and attached Figure 6 When the stirring shaft 13 rotates, it drives the push ring 26 to rotate. Since the push rack 22 slides in the front-to-back direction, the push shaft 25 drives the sliding frame 24 to move in the front-to-back direction. When the push rack 22 moves, it contacts the cleaning gear 20, causing the cleaning gear 20 to rotate. The cleaning gear 20 causes the flip shaft 19 to rotate, thereby driving the flip rod 21 and the connected dust plate to rotate. The dust plate is a general term for the first dust plate 10 and the second dust plate 15.

[0050] Then, when the dustproof plate rotates, it will enter below the liquid level of the condensed water in the cleaning water tank 7. The side of the dustproof plate that absorbs dust will enter the condensed water. The condensed water is rotated by the stirring shaft 13, and the impurities attached to the dustproof plate are cleaned by the condensed water. In this way, the cleaning of impurities on the dustproof plate can be effectively improved, and the dustproof plate is repeatedly rotated within this limit. While cleaning, it can also adhere to a part of the condensed water. When the outside air flows into the heat dissipation box 3, the condensed water can play a role in cooling. The cooled air will flow through the surface of the air guide hood 2, and the heat emitted by the transformer body 1 will be taken away. In addition, the heat that flows out through the heat outlet 27 mentioned above will also be taken away by the cooled air, which can speed up the heat dissipation of the heat outlet 27.

[0051] A detachably connected filter screen 9 is provided on one end of the condensation pipe 8 located in the cleaning water tank 7 , and the filter screen 9 is used to prevent impurities during cleaning from flowing into the condensation pipe 8 .

[0052] A filter plate is provided on the inner side of the air outlet 5 to prevent external dust from entering the heat dissipation box 3 when the air is stationary. The filter plate can be detachably provided. Since this is the outlet of the air flow, dust will not adhere to the surface of the filter plate, and the air flow will clean the surface of the filter plate, so no impurity removal part is provided here.
