Description

Technical Field

[0001] This application relates to the technical field of dry-type transformers, and in particular to a dry-type transformer. Background Technology

[0002] A dry-type transformer is a power device that converts voltage through electromagnetic induction. Dry-type transformers rely on air, epoxy resin, or other solid materials for insulation and heat dissipation. Dry-type transformers are typically installed in power generation, industrial and infrastructure, public buildings, power transmission and distribution networks, and other similar locations.

[0003] In related technologies, dry-type transformers include a housing, a fan on the outer surface of the housing that blows air onto the housing, and water-cooling pipes on the housing located in the path of the fan.

[0004] If the water cooling pipe malfunctions, the staff needs to remove the water cooling pipe from the casing. At this time, the transformer will be very hot because only the fan is blowing, which will affect the use of the transformer. Summary of the Invention

[0005] To address the issue that disassembling the water-cooling pipe during a water-cooling pipe failure would affect the normal operation of the transformer, this application provides a dry-type transformer.

[0006] This application provides a dry-type transformer, which adopts the following technical solution:

[0007] A dry-type transformer includes a housing, a fan mounted on the housing, a water-cooling pipe mounted on the housing, a plurality of water-cooling plates mounted on the water-cooling pipe, a first connector mounted on the water-cooling plate, and a plurality of second connectors mounted on the water-cooling pipe; when the first connector is connected to the second connector, the water-cooling plate is connected to the water-cooling pipe.

[0008] By adopting the above technical solution, the water-cooled plate and the water-cooled pipe are connected through the first connector and the second connector, so that the water-cooled pipe can drive the water in the water-cooled plate to flow, thereby allowing the water in the water-cooled plate to cool the air. This reduces the temperature of the air blown by the fan, reduces the possibility that the fan's air blowing effect will be weakened due to high outside temperature, and thus allows the transformer to be used stably.

[0009] Optionally, the water-cooled plate is provided with air holes for airflow, and multiple movable holes are provided on the surface of the air holes near the shell, the movable holes communicating with the air holes.

[0010] By adopting the above technical solution, when the fan starts, the air blown by the fan moves along the direction of the air vents and the moving holes to the housing, allowing the air to reach the housing through the water cooling plate more effectively, thereby increasing the cooling effect of the air.

[0011] Optionally, a guide block is provided on the wall of the movable hole, and a guide slope is provided on the guide block. The distance between the guide slope and the housing gradually decreases along the distance from the water-cooled plate to the fan.

[0012] By adopting the above technical solution, a guide slope is provided on the guide block, and the distance between the guide slope and the shell gradually decreases along the distance from the water-cooling plate to the fan. This allows air to move along the inclined direction of the guide slope, enabling the air to flow towards the ground. This allows the cold air to flow near the shell to a greater extent, thus maximizing the cooling effect on the shell. It also reduces the possibility of the cold air passing directly through the shell, which would result in a poor cooling effect, further increasing the cooling effect of the cold air on the shell.

[0013] Optionally, the housing is provided with a fixing plate, and the fixing plate has multiple mounting slots extending to the surface of the fixing plate near the housing. The mounting slots are for mounting the water-cooling plate. The mounting slots are provided with mounting springs, and the mounting springs are provided with mounting blocks. The water-cooling plate has grooves for the mounting blocks to be inserted into. The mounting springs drive the mounting blocks to be inserted into the grooves. When the mounting blocks are inserted into the grooves, the water-cooling plate is fixed in the mounting slots.

[0014] By adopting the above technical solution, the water-cooled plate is fixed to the fixed plate by inserting the spring-driven mounting block into the groove. This reduces the possibility of damage to the connection between the water-cooled plate and the water-cooled pipes caused by transformer vibration. When the water-cooled plate is damaged, the operator only needs to remove the replacement water-cooled plate, facilitating the installation and removal of the water-cooled plate. In cold environments such as winter, only a small number of water-cooled plates can be installed, while in hot environments such as summer, a larger number of water-cooled plates can be installed, allowing the water-cooled plates to dynamically adjust to different environments for the benefit of the transformer.

[0015] Optionally, the mounting block is provided with a mounting ramp, and the distance between the mounting ramp and the housing gradually increases along the direction from the fixing plate to the fan.

[0016] By adopting the above technical solution, when the water-cooled plate is not installed on the fixed plate, the mounting spring drives the mounting block to protrude. The distance between the mounting slope and the housing gradually decreases along the direction from the fixed plate to the fan, allowing air to flow through the inclined direction of the mounting slope and quickly pass through the housing, increasing the airflow at the housing and enabling the housing temperature to drop rapidly.

[0017] Optionally, a placement block is provided on the groove wall of the groove, and a placement slope is provided on the placement block. The distance between the placement slope and the mounting spring gradually increases along the direction from the housing to the water-cooling plate. When the water-cooling plate slides in the mounting groove, the placement slope is used to drive the mounting block to disengage from the groove.

[0018] By adopting the above technical solution, when the water-cooled plate slides in the mounting groove, the distance between the inclined plane and the mounting spring gradually increases along the direction from the shell to the water-cooled plate. The inclined plane drives the mounting block to disengage from the groove, thereby releasing the mounting block from limiting the water-cooled plate and allowing the water-cooled plate to be smoothly removed from the mounting groove, so that the staff can replace the water-cooled plate.

[0019] Optionally, the fixing plate is provided with a dustproof net, and a cleaning brush is slidably connected to the fixing plate. The cleaning brush is located on the moving path of the water-cooling plate. When the water-cooling plate is installed on the fixing plate, the cleaning brush can clean the dustproof net.

[0020] By adopting the above technical solution, when the water-cooled plate is installed on the fixed plate, the cleaning brush is located on the moving path of the water-cooled plate, which enables the water-cooled plate to drive the cleaning brush to move, allowing the cleaning brush to clean the dust screen and reduce the dust accumulated on the dust screen; the dust screen can be cleaned by replacing the water-cooled plate, so that the staff do not need to clean the dust screen specially, reducing the number of operation steps for the staff.

[0021] Optionally, the cleaning brush is provided with a reset spring, which drives the cleaning brush to reset; when the water-cooled plate does not contact the cleaning brush, the reset spring drives the cleaning brush to reset.

[0022] By adopting the above technical solution, when the staff removes the water-cooling plate, the water-cooling plate does not come into contact with the cleaning brush, allowing the return spring to drive the cleaning brush to move, so that the cleaning brush can clean the dust screen; at the same time, it facilitates the cleaning of the dust screen by the cleaning brush when the next water-cooling plate is installed.

[0023] Optionally, a limiting plate for blocking the first and second connecting members is slidably connected to the fixing plate, a baffle is slidably connected to the fixing plate, the baffle has a receiving hole for storing dust, a gear set is provided on the fixing plate, the limiting plate and the baffle are both meshed on the gear set, and a collection hole for dust to pass through is provided on the fixing plate; when the limiting plate does not block the first and second connecting members, the receiving hole is aligned with the collection hole.

[0024] By adopting the above technical solution, the operator slides the limiting plate, which drives the baffle to move via the gear set, aligning the collection hole with the receiving hole. This allows the dust in the receiving hole to move into the collection hole, facilitating cleaning of the dust in the collection hole. By storing the dust in both the receiving hole and the collection hole, excessive dust accumulation in the receiving hole prevents it from being blown away by airflow, reducing the problem of large amounts of dust being blown away by airflow. The operator can also move the accumulated dust by replacing or installing the water-cooling plate, avoiding a series of problems caused by excessive dust accumulation.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The water-cooled plate and the water-cooled pipe are connected by the first connector and the second connector, so that the water-cooled pipe can drive the water in the water-cooled plate to flow, thereby allowing the water in the water-cooled plate to cool the air. This reduces the temperature of the air blown by the fan, reducing the possibility that the fan's air blowing effect will be weakened due to high outside temperature, and thus allowing the transformer to be used stably.

[0027] 2. The water-cooled plate and the water-cooled pipe are connected by the first connector and the second connector, so that the water-cooled pipe can drive the water in the water-cooled plate to flow, thereby allowing the water in the water-cooled plate to cool the air. This reduces the temperature of the air blown by the fan, reducing the possibility that the fan's air blowing effect will be weakened due to high outside temperature, and thus allowing the transformer to be used stably.

[0036] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0037] This embodiment discloses a dry-type transformer. (Refer to...) Figure 1 A dry-type transformer includes a housing 1, on both sides of which a fan 11 is bolted. The fan 11 can blow air from the ground in a vertically upward direction.

[0038] Reference Figure 1 and Figure 2 A fixing plate 2 is fixedly connected to the surface of the housing 1, and the fixing plate 2 surrounds the circumference of the housing 1. A water-cooling pipe 3 is fixedly connected to the outer surface of the fixing plate 2, and the water-cooling pipe 3 extends along the circumference of the housing 1. A water-cooling component 31 is fixedly connected to the water-cooling pipe 3, and the water-cooling component 31 achieves water-cooling circulation through the water-cooling pipe 3.

[0039] Reference Figure 2 and Figure 3 The mounting plate 2 has multiple mounting slots 21 on its surface away from the ground, extending through the surface of the mounting plate 2 near the housing 1 along the direction from the mounting plate 2 to the housing 1. The mounting plate 2 has through holes 22 communicating with the mounting slots 21, allowing air blown by the fan 11 to pass through. Multiple water-cooling plates 32 are mounted on the mounting plate, each capable of being installed in a corresponding mounting slot 21. A first connector 33 is fixedly connected to each water-cooling plate 32, and multiple second connectors 34 are fixedly connected to each water-cooling pipe 3. The first connectors 33 and second connectors 34 can be interconnected. When the first connectors 33 and second connectors 34 are interconnected, the water-cooling pipe 3 and the water-cooling plate 32 can communicate with each other. The first connectors 33 and second connectors 34 are quick-connect couplings.

[0040] Reference Figure 3 and Figure 4 The mounting groove 21 has a placement groove 23 on its wall. A mounting spring 231 is fixedly connected to the bottom wall of the placement groove 23. A mounting block 232 is fixedly connected to the surface of the mounting spring 231 away from the bottom wall of the placement groove 23. The mounting spring 231 drives the mounting block 232 to protrude out of the placement groove 23. When the mounting block 232 protrudes out of the placement groove 23, the mounting spring 231 is in a non-stressed state; when the mounting block 232 is completely inside the placement groove 23, the mounting spring 231 is in a compressed state.

[0041] Reference Figure 1 and Figure 4 The mounting block 232 has a mounting ramp 233 on its surface away from the ground. The distance between the mounting ramp 233 and the ground gradually decreases along the direction from the housing 1 to the fixing plate 2. The mounting ramp 233 is located on the gas movement path.

[0042] Reference Figure 4 and Figure 5 The surface of the water-cooled plate 32 has a groove 321 for inserting the mounting block 232. When the mounting block 232 is inserted into the groove 321, the water-cooled plate 32 is fixed in the mounting groove 21. A placement block 322 is fixedly connected to the groove wall of the groove 321. A placement ramp 323 is formed on the surface of the placement block 322. The distance between the placement ramp 323 and the mounting spring 231 gradually increases along the direction from the housing 1 to the water-cooled plate 32. When the water-cooled plate 32 slides in the mounting groove 21, the mounting block 232 moves along the inclined direction of the placement ramp 323, allowing the mounting block 232 to move from the mounting groove 21 into the placement groove 23, so that the mounting block 232 does not fix the water-cooled plate 32, allowing the water-cooled plate 32 to be removed from the mounting groove 21.

[0043] Reference Figure 3 The surface of the water-cooled plate 32 has vent holes 35 extending along its length. Multiple movable holes 351 are formed on the side of the water-cooled plate 32, communicating with the vent holes 35, and are arranged in an array along the length of the water-cooled plate 32. A guide block 352 is integrally formed on the surface of the movable hole 351 away from the ground. A guide ramp 353 is formed on the surface of the guide block 352, and the distance between the guide ramps 353 and the ground surface gradually decreases along the direction from the fixed plate 2 to the housing 1. The vent holes 35 flowing within the movable holes 351 can flow along the guide ramps 353.

[0044] Reference Figure 3Air is blown from the fan 11 and passes through the perforation 22, the air hole 35 and the moving hole 351 in sequence, allowing the water-cooled plate 32 to cool the air. The cold air flows along the inclined direction of the guide slope 353, allowing the cold air to flow in the direction between the shell 1 and the ground, greatly increasing the residence time of the cold air between the shell 1 and the fixed plate 2, allowing the cold air to further reduce the temperature of the shell 1.

[0045] Reference Figure 3 Multiple dustproof nets 24 are fixedly connected to the fixing plate 2. The dustproof nets 24 are fixedly connected to the side of the mounting groove 21 near the housing 1, that is, when air flows into the housing 1, it needs to pass through the dustproof nets 24. The dustproof nets 24 extend along the height direction of the fixing plate 2.

[0046] Reference Figure 3 and Figure 5 Two return springs 241 are fixedly connected to the wall of the mounting groove 21. A cleaning brush 242 is provided inside the mounting groove 21, which can clean the dust screen 24. The return springs 241 are fixedly connected to the cleaning brush 242 on the surface away from the ground, and the return springs 241 drive the cleaning brush 242 to move away from the ground. When the cleaning brush 242 abuts against the side of the dust screen 24 away from the ground, the return springs 241 are in a non-stressed state; when the cleaning brush 242 abuts against the side of the dust screen 24 close to the ground, the return springs 241 are in a compressed state.

[0047] Reference Figure 3 and Figure 5 A connecting block 36 is fixedly connected to the surface of the water-cooled plate 32, and the connecting block 36 is located on the moving path of the cleaning brush 242. When the water-cooled plate 32 is installed in the mounting groove 21, the connecting block 36 drives the cleaning brush 242 to fall, allowing the cleaning brush 242 to clean the dust filter 24.

[0048] Reference Figure 3 and Figure 6 The fixed plate 2 has a movable hole 25, and a baffle 251 is slidably connected inside the movable hole 25. The fixed plate 2 has a through hole 252 that connects to the mounting groove 21 and the movable hole 25, allowing dust to fall through. A dust-storing groove 254 is formed on the surface of the baffle 251, and a dust-storing hole 253 is formed in the groove 254. A receiving slope 255 is formed on the bottom wall of the groove 254, inclined towards the receiving hole 253 to facilitate dust accumulation at the receiving hole 253. A collection hole 28 is formed on the fixed plate 2 for collecting dust. When the baffle 251 is completely inside the through hole 252, the receiving hole 253 is directly below the through hole 252.

[0049] Reference Figure 3 and Figure 6When the water-cooled plate 32 is installed in the mounting groove 21, the cleaning brush 242 can block the opening of the receiving hole 253 to reduce the problem of dust floating in the receiving groove 254 due to airflow. When the baffle 251 moves away from the housing 1, the receiving hole 253 can align with the collection hole 28, at which time dust can move from the receiving hole 253 into the collection hole 28, so as to facilitate the cleaning of dust by the staff.

[0050] Reference Figure 3 and Figure 7 A limiting plate 26 is slidably connected to the fixed plate 2. A limiting groove 261 is provided on the surface of the limiting plate 26 near the ground for the first connecting piece 33 and the second connecting piece 34 to be inserted. The limiting groove 261 extends through to the side of the limiting plate 26 near the water cooling pipe 3.

[0051] Reference Figure 3 and Figure 7 Multiple gear sets 27 are rotatably connected to the fixed plate 2. Each gear set 27 includes a rotating rod 271, a first gear 272, and a second gear 273. The rotating rod 271 is rotatably connected to the fixed plate 2, and both the first gear 272 and the second gear 273 are fixedly connected to the rotating rod 271. The diameter of the second gear 273 is larger than the diameter of the first gear 272. A rack meshing with the first gear 272 is fixedly connected to the limiting plate 26, and a rack meshing with the second gear 273 is fixedly connected to the baffle 251. When the limiting plate 26 moves, the limiting plate 26 drives the baffle 251 to move via the first gear 272.

[0052] Reference Figure 3 , Figure 6 and Figure 7 When the staff slides the limiting plate 26, the first connecting piece 33 and the second connecting piece 34 are disengaged from the limiting groove 261. The limiting plate 26 drives the first gear 272 to rotate, and the first gear 272 drives the second gear 273 to rotate through the rotating rod 271. The second gear 273 drives the baffle 251 to move, so that the receiving hole 253 is aligned with the collection hole 28, so that the staff can clean the dust in the receiving hole 253.

[0053] The implementation principle of a dry-type transformer in this application embodiment is as follows: The operator first installs the water-cooled plate 32 on the fixed plate 2, then slides the water-cooled plate 32 so that the mounting block 232 is located in the groove 321, driving the first connector 33 and the second connector 34 to communicate with each other, and finally slides the limiting plate 26 so that the limiting groove 261 in the limiting plate 26 blocks the first connector 33 and the second connector 34.
