Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a multi-channel circulating cooling dry-type transformer and a control method thereof. Background Art

[0002] Dry-type transformers are widely used in various indoor power distribution and special environments due to their high safety, environmental protection, low maintenance requirements and strong adaptability.

[0003] Dry-type transformers usually rely on natural convection of air to dissipate heat and are suitable for small-capacity transformers. Since they do not use oil as a cooling medium, they avoid the risks of oil leakage, fire and explosion. They are particularly suitable for places with high safety requirements, such as high-rise buildings, subways, hospitals, etc.

[0004] If the temperature of the dry-type transformer rises during use, the fan can be used to force air flow to enhance the heat dissipation effect. The existing fan blows air into the cooling pipeline, and the air usually circulates evenly along the pipeline trajectory. The air is in a laminar state in the pipeline. In the laminar flow, the air flows in layers, and there is less mixing between the layers, resulting in heat transfer mainly relying on heat conduction, and the convection effect is weak, which reduces the heat exchange efficiency. Even if the fan power is increased, the heat dissipation effect that can be achieved is still not high. Summary of the invention

[0008] As a further solution of the present invention: the turbulence control mechanism includes a second cooling pipe installed on the support plate, the second cooling pipe is connected to a plurality of turbulence pipes which are equidistantly distributed and connected to the first cooling pipe, and a guide assembly is arranged on the support plate.

[0009] As a further solution of the present invention: the guide assembly includes a guide rail installed on the support plate, a conduction plate slidably installed on the guide rail and slidably connected to the cooling box, the cooling box is provided with a cylinder fixedly connected to the conduction plate, and the conduction plate is provided with an air supply structure connected to the first cooling pipe and the second cooling pipe.

[0010] As a further solution of the present invention: the air supply structure includes a through groove opened on the conductive plate, and a first conductive hole and a second conductive hole are opened in the through groove. The first conductive hole is conductively matched with the first cooling pipe, and the second conductive hole is conductively matched with the second cooling pipe.

[0011] As a further solution of the present invention: the follow-up adjustment mechanism includes a slot provided on the side wall of the support plate, a sliding block fixedly connected to the conduction plate is slidably installed in the slot, a hinged rod is hinged on the sliding block, and an elastic component connected to the hinged rod is arranged on the first cooling pipe.

[0012] As a further solution of the present invention: the elastic component includes a sliding sleeve slidably mounted on the first cooling tube and hinged to the hinged rod, a symmetrically arranged receiving plate is provided on the first cooling tube, a spring is sleeved on the first cooling tube, two ends of the spring are respectively abutted against the sliding sleeve and the receiving plate, and a driven structure connected to the receiving plate is provided on the sliding sleeve.

[0013] As a further solution of the present invention: the driven structure includes a sliding groove opened on the receiving plate and symmetrically arranged, a movable block is slidably installed in the sliding groove, a symmetrically arranged supporting sleeve is arranged on the sliding sleeve, and a support rod fixedly connected to the movable block is slidably installed in the supporting sleeve.

[0014] As a further solution of the present invention: the drainage assembly includes a guide column installed on the movable block, and a plurality of guide sleeves equidistantly distributed are slidably installed on the guide column, and the guide sleeve is fixedly connected to the air guide plate, and a sealing sleeve is provided on the circumferential outer wall of the first cooling pipe, and the sealing sleeve is slidably connected to the air guide plate.

[0015] A control method for multi-channel circulation cooling of dry-type transformers, comprising the following steps: Step 1: absorbing and cooling the outside air through the circulating cooling component, and conveying the gas to the first cooling pipe for laminar flow through the turbulence control mechanism; Step 2: The turbulence control mechanism can move when the temperature in the protective box increases, and control the first cooling pipe and the circulating cooling component to be in a blocked state; Step 3: The circulating cooling component will transport air to the first cooling pipe through the turbulence control mechanism and adjust the air circulation state in the first cooling pipe; Step 4: The turbulence control mechanism will also drive the follow-up adjustment mechanism to move, so as to control the air guide plate to be inserted into the first cooling pipe through the drainage component.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the present application can increase the contact area and heat exchange time between the cooling gas and the heat source by breaking the air laminar flow, thereby increasing the cooling effect. Specifically, when the circulating cooling component is working, it can absorb and cool the external air, and transport it to the first cooling pipe through the turbulence control mechanism to form a laminar flow for heat exchange and cooling treatment. If the temperature is still in an elevated state, the first cooling pipe is blocked under the action of the turbulence control mechanism, and the circulating cooling component will form turbulence in the first cooling pipe through the turbulence control mechanism. At the same time, under the action of the turbulence control mechanism, the follow-up adjustment mechanism is controlled to move, so as to control the air guide plate to be inserted into the first cooling pipe through the drainage component. Under the synchronous action of the turbulence control mechanism and the air guide plate, the air in the first cooling pipe breaks the laminar flow and forms an irregular turbulent state to further enhance the cooling effect.

[0017] The air entering the first cooling pipe through the turbulence pipe will first collide with the first cooling pipe to enhance the heat exchange with the heat source. Under the action of air pressure, it will gradually flow toward the discharge pipe and be disturbed again under the impact of the air delivered by the next turbulence pipe until the air is discharged out of the protective box. Through the cooperation of multiple turbulence pipes, the air circulation in the first cooling pipe can always maintain a disordered turbulent state to increase the cooling effect.

[0018] When the air transported by the turbulence pipe to the first cooling pipe flows through the air guide vanes, the air in the first cooling pipe flows along the trajectory of the air guide vanes under the guidance of the two air guide vanes and impacts each other, so that the air flow direction in the first cooling pipe is further disturbed. The air guide vanes also have the effect of gathering air, which increases the air pressure flowing through the air guide vanes, making the air flow turbulent and increasing the flow rate.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] See also Figure 1 to Figure 10 In an embodiment of the present invention, a multi-channel circulating cooling dry-type transformer includes: A protection box 1, and a support truss 2 installed in the protection box 1, wherein a transformer body 3 and a water tank 6 are arranged on the support truss 2; Also includes: A circulating cooling component is arranged in the protective box 1 and connected to the water tank 6, the circulating cooling component is connected to a support plate 5, the support plate 5 is provided with a first cooling pipe 15, and the first cooling pipe 15 is provided with a discharge pipe 1501; A turbulence control mechanism, which is disposed on the support plate 5 and connected to the circulating cooling assembly and the first cooling pipe 15, and is used to adjust the conduction and air supply state of the first cooling pipe 15; The follow-up adjustment mechanism is arranged on the first cooling tube 15 and connected to the turbulence control mechanism. The first cooling tube 15 is also provided with a drainage component connected to the follow-up adjustment mechanism. The drainage component is connected to an air guide plate 29. The follow-up adjustment mechanism can adjust the distance between the air guide plate 29 and the first cooling tube 15 through the drainage component when the turbulence control mechanism moves.

[0033] Specifically, ventilation slots 101 are provided on both sides of the protection box 1. When the transformer body 3 needs to be cooled, under the action of the circulating cooling component, the outside air is sucked into the circulating cooling component through one of the ventilation slots 101 to cool the air. The cooled air will be transported to the first cooling pipe 15 and exchange heat with the heat generated by the transformer body 3 to cool the transformer body 3. The air after the heat exchange will be discharged to the outside of the protection box 1 through the exhaust pipe 1501 and the other ventilation slots 101. If the temperature in the protection box 1 continues to rise, since the air flow directly transported to the first cooling pipe 15 is in a laminar state, the heat conduction mainly depends on the heat conduction effect, and the convection effect is weak, so that the heat exchange efficiency is not high. Therefore, under the action of the turbulence control mechanism, The first cooling pipe 15 and the circulating cooling component are in a blocked state. At this time, the cold air transported by the circulating cooling component will enter the first cooling pipe 15 through the turbulence control mechanism. Under the action of the turbulence control mechanism, the air forms an irregular turbulent state in the first cooling pipe 15, thereby breaking the boundary layer, enhancing heat exchange, and increasing the heat exchange time with the heat source, further enhancing the cooling effect. At the same time, the turbulence control mechanism will also drive the follow-up adjustment mechanism to move, and control the air guide plate 29 to be inserted into the first cooling pipe 15 through the drainage component. When the air in the turbulent state flows to the air guide plate 29, the air flow direction is changed again when guided by the air guide plate 29, and the mutual impact between the flowing air is controlled, thereby having a turbulent effect on the air, so as to further enhance the heat dissipation effect on the transformer body 3.

[0034] See also Figure 1-Figure 3 , Figure 5-Figure 7 The circulating cooling assembly includes a fan 14 installed in the protective box 1, a cooling box 4 is arranged on the fan 14, the cooling box 4 is fixedly connected to the support plate 5, a water pump 7 is arranged on the top of the water tank 6, an absorption pipe 8 and a circulating conveying pipe 9 are connected to the water pump 7, the absorption pipe 8 is connected to the water tank 6, and the circulating conveying pipe 9 passes through the cooling box 4 and is connected to the water tank 6.

[0035] In detail, the water tank 6 is filled with coolant, the absorption tube 8 is connected to the side bottom of the water tank 6, and the circulation delivery tube 9 is connected to the side top of the water tank 6. When the fan 14 is working, under the action of the fan 14, the outside air is blown into the cooling box 4 through one of the ventilation slots 101. At the same time, the water pump 7 works and delivers the coolant at the bottom of the water tank 6 to the circulation delivery tube 9 through the absorption tube 8. The circulation delivery tube 9 is arranged in a corrugated shape in the cooling box 4. Under the action of the circulation delivery tube 9, the contact area between the coolant and the air in the cooling box 4 is increased, thereby cooling the air more comprehensively. With the circulation of the coolant, the coolant in the circulation delivery tube 9 will flow back to the water tank 6 and be located at the top layer of the coolant in the water tank 6. The coolant is continuously circulated, thereby achieving cooling of the air.

[0036] Preferably, since the coolant absorbed by the absorption tube 8 is located at the bottom of the water tank 6, the temperature of the coolant in this part is at a relatively low level, and the coolant flowing back into the water tank 6 in the circulation delivery tube 9 is at the top of the water tank 6. Therefore, it can get enough time to cool down when it is absorbed by the absorption tube 8 next time, so as to ensure subsequent normal use.

[0037] See also Figure 2 , Figure 3 , Figure 5-Figure 7 The turbulence regulating mechanism includes a second cooling pipe 16 installed on the support plate 5, and a plurality of turbulence pipes 17 equidistantly distributed and connected to the first cooling pipe 15 are connected to the second cooling pipe 16. A guide assembly is provided on the support plate 5, wherein the guide assembly includes a guide rail 501 installed on the support plate 5, and a conduction plate 10 slidably connected to the cooling box 4 is slidably installed on the guide rail 501, and a cylinder 13 fixedly connected to the conduction plate 10 is provided on the cooling box 4, and an air supply structure connected to the first cooling pipe 15 and the second cooling pipe 16 is provided on the conduction plate 10, and the air supply structure includes a through groove 1001 opened on the conduction plate 10, and a first conduction hole 11 and a second conduction hole 12 are opened in the through groove 1001, the first conduction hole 11 is in conduction with the first cooling pipe 15, and the second conduction hole 12 is in conduction with the second cooling pipe 16.

[0038] It should be noted that when the temperature in the protection box 1 is low, the cooled air can be directly transported through the first cooling pipe 15. At this time, under the action of the cylinder 13, the conduction plate 10 is located at the end of the stroke away from the supporting truss 2, the first conduction hole 11 and the first cooling pipe 15 are in a conducting state, and the second conduction hole 12 and the second cooling pipe 16 are in a misaligned state, so that the second cooling pipe 16 is in a blocked state, and the cooled air in the cooling box 4 will be transported to the first cooling pipe 15 through the through groove 1001 and the first conduction hole 11, so as to cool the transformer body 3; If the temperature of the transformer body 3 is still in an elevated state, it indicates that the cooling effect on the transformer body 3 needs to be enhanced. At this time, the cylinder 13 works and drives the conduction plate 10 to move along the length direction of the guide rail 501. The conduction plate 10 also drives the first conduction hole 11 and the second conduction hole 12 to move, so that the first conduction hole 11 is separated from the first cooling pipe 15, and the first cooling pipe 15 will be in a blocked state. When the second conduction hole 12 moves to a position connected to the second cooling pipe 16, at this time, the air in the cooling box 4 will enter the second cooling box 4 through the second conduction hole 12. In the tube 16, one end of the second cooling tube 16 is connected to the second conducting hole 12, and the other end is in a blocked state. Therefore, the air in the second cooling tube 16 will be transported to the first cooling tube 15 through multiple turbulence tubes 17. Under the action of the turbulence tubes 17, the air in the first cooling tube 15 forms an irregular turbulent state, thereby breaking the laminar boundary layer and enhancing heat exchange. As the air in the first cooling tube 15 flows to the discharge pipe 1501, the air will be discharged through another ventilation slot 101, and the above steps are repeated to cool the transformer body 3.

[0039] Preferably, if the air circulates directly in the first cooling tube 15, the air circulation will be in a laminar state, and the air entering the first cooling tube 15 through the turbulence tube 17 will first collide with the first cooling tube 15 to enhance the heat exchange with the heat source, and under the action of air pressure, gradually flow toward the discharge tube 1501, and under the impact of the air delivered by the next turbulence tube 17, the air is disturbed again until the air is discharged out of the protective box 1. Through the cooperation of multiple turbulence tubes 17, the air circulation in the first cooling tube 15 can always maintain a disordered turbulent state to increase the cooling effect.

[0040] See also Figure 2-Figure 6 , Figure 8 , Fig. 9The follow-up adjustment mechanism includes a slot 18 provided on the side wall of the support plate 5, a sliding block 19 fixedly connected to the conduction plate 10 is slidably installed in the slot 18, a hinge rod 20 is hinged on the sliding block 19, an elastic component connected to the hinge rod 20 is provided on the first cooling tube 15, wherein the elastic component includes a sliding sleeve 21 slidably installed on the first cooling tube 15 and hinged to the hinge rod 20, a symmetrically arranged receiving plate 22 is provided on the first cooling tube 15, and the first cooling tube 15 is provided with a receiving plate 22. A spring 26 is sleeved on the tube 15, and the two ends of the spring 26 are respectively in contact with the sliding sleeve 21 and the receiving plate 22. The sliding sleeve 21 is provided with a driven structure connected to the receiving plate 22, and the driven structure includes a sliding groove 2201 opened on the receiving plate 22 and symmetrically arranged, and a movable block 23 is slidably installed in the sliding groove 2201. The sliding sleeve 21 is provided with a symmetrically arranged supporting sleeve 24, and a supporting rod 25 fixedly connected to the movable block 23 is slidably installed in the supporting sleeve 24.

[0041] Further, the support sleeve 24 and the support rod 25, the sliding sleeve 21, and the movable block 23 are combined in the same vertical plane to form a vertical triangle system. When the first cooling pipe 15 and the first conducting hole 11 are in a conducting state, it means that the conducting plate 10 is located at the end of the travel in the direction away from the supporting truss 2. Under the action of the conducting plate 10, the sliding block 19 is located at the end of the travel in the direction of the slot 18 away from the first cooling pipe 15. The sliding block 19 will control the sliding sleeve 21 to be located in the direction toward the support plate 5 through the hinge rod 20. At the end of the stroke, in the vertical triangle system, the distance between the sliding sleeve 21 and the receiving plate 22 is the largest, which means that in the vertical triangle system, one of the right-angle sides is the longest. Therefore, the hypotenuse formed by the support sleeve 24 and the support rod 25 is the longest, and the size of the mutual fit is the smallest. The movable block 23 is located at the end of the stroke on the side of the slide groove 2201 away from the first cooling pipe 15. Under the action of the drainage component, the air guide plate 29 is located outside the first cooling pipe 15 and will not affect the air flow direction in the first cooling pipe 15. If the temperature in the protection box 1 is in an elevated state, under the action of the cylinder 13, the conduction plate 10 is controlled to move, so that the first conduction hole 11 is separated from the first cooling pipe 15, and the second conduction hole 12 is connected to the second cooling pipe 16, so as to control the air to form a turbulent state in the first cooling pipe 15 through the turbulent pipe 17. At the same time, the conduction plate 10 will also drive the sliding block 19 to move along the length direction of the slot 18, so as to control the sliding sleeve 21 to move in a direction away from the support plate 5 through the hinge rod 20 to compress the spring 26. The sliding sleeve 21 will also drive the support sleeve 24 to move, so that the size of the mutual fitting of the support sleeve 24 and the support rod 25 increases. Since in the vertical triangle system, the length of one of the right-angle sides represented by the sliding sleeve 21 is reduced, under the action of the support sleeve 24 and the support rod 25, the movable block 23 also slides along the length direction of the slide groove 2201 and moves toward the first cooling pipe 15, so as to drive the guide column 27 to move toward the first cooling pipe 15 through the drainage assembly; Preferably, when the conduction plate 10 moves, it is possible to adjust the conduction state between the first conduction hole 11 and the first cooling tube 15, and the second conduction hole 12 and the second cooling tube 16 to change the state of air circulation, and synchronously control the movement of the follow-up adjustment mechanism to change the position of the air guide plate 29, thereby simplifying the driving source and achieving the effect of precise and stable adjustment.

[0042] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Fig.10 The drainage assembly includes a guide column 27 installed on the movable block 23, and a plurality of guide sleeves 28 equidistantly distributed are slidably installed on the guide column 27. The guide sleeves 28 are fixedly connected to the air guide plates 29. A sealing sleeve 30 is provided on the circumferential outer wall of the first cooling tube 15, and the sealing sleeve 30 is slidably connected to the air guide plates 29.

[0043] Furthermore, the air guide pieces 29 are symmetrically arranged on the first cooling pipe 15. When the first conducting hole 11 and the first cooling pipe 15 are in a conducting state, the movable block 23 is at the end of the stroke in the direction away from the first cooling pipe 15, so that the air guide pieces 29 are controlled to be outside the first cooling pipe 15 through the guide column 27 and the guide sleeve 28, and under the action of the air guide pieces 29 and the sealing sleeve 30, it is ensured that the side wall of the first cooling pipe 15 is in a blocked state; When the first conducting hole 11 is separated from the first cooling tube 15, and the second conducting hole 12 is connected to the second cooling tube 16, under the action of the follow-up adjustment mechanism, the movable block 23 moves toward the first cooling tube 15, thereby driving the guide column 27 to move, and the guide column 27 will drive the guide sleeve 28 to move toward the first cooling tube 15 to control the movement of the air guide plate 29. The air guide plate 29 will slide along the trajectory of the sealing sleeve 30, so that the guide sleeve 28 will also move along the length direction of the guide column 27. When the second conducting hole 12 is connected to the second cooling tube 16, the air guide plate 29 will slide along the trajectory of the sealing sleeve 30, so that the guide sleeve 28 will also move along the length direction of the guide column 27. The amount of the sheet 29 inserted into the first cooling tube 15 reaches the maximum. Since the air guide sheet 29 is arranged obliquely relative to the inner wall of the first cooling tube 15, when the air delivered to the first cooling tube 15 by the turbulence tube 17 flows through the air guide sheet 29, under the guidance of the two air guide sheets 29, the air in the first cooling tube 15 flows along the trajectory of the air guide sheet 29 and impacts each other, so that the air flow direction in the first cooling tube 15 is further disturbed. The air guide sheet 29 also has the effect of gathering air, which increases the air pressure flowing through the air guide sheet 29, making the air flow turbulent and increasing the flow rate.

[0044] Preferably, since the air guide plates 29 and the turbulence ducts 17 are adjacently and staggeredly distributed, when the air whose wind direction and flow rate are changed by the air guide plates 29 and then impacted by the air transported by the turbulence ducts 17, the air in the first cooling tube 15 will change direction again to increase the contact time and contact area between the air and the heat source, thereby improving the heat dissipation efficiency.
