Description

Technical Field

[0001] This utility model relates to the field of dry-type transformers, and in particular to a dry-type transformer with auxiliary heat dissipation function. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, a dry-type transformer is a transformer whose core and windings are not immersed in insulating oil. A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Dry-type transformers are a commonly used type of transformer.

[0003] In the existing technology, after a long period of use, the dry-type transformer itself generates high temperature. At this time, in order to ensure the stable operation of the dry-type transformer, natural air cooling is often used. However, the efficiency of natural air cooling is low, which can easily make the dry-type transformer work unstablely. Utility Model Content

[0004] This utility model provides a dry-type transformer with auxiliary heat dissipation function. By setting up an air-cooling component, which uses a fan and water-cooling pipes, the airflow drawn in from one end of the fan is cooled by the water-cooling pipes to form a low-temperature airflow, and then blown out from the other end of the fan to the surface of the dry-type transformer. This low-temperature airflow reduces the surface temperature of the dry-type transformer, effectively reducing the temperature of the dry-type transformer and ensuring the stable operation of the dry-type transformer.

[0005] To achieve the above objectives, this utility model provides a dry-type transformer with auxiliary heat dissipation function, comprising:

[0009] Multiple air-cooled components are arranged on the air-cooled mounting bracket. Each air-cooled component includes an air-cooled housing, water-cooled pipes, and a fan. The air-cooled housing has a hollow cavity extending through it. A filter slot is opened on one side of the air-cooled housing and communicates with the hollow cavity. The water-cooled pipes are arranged in the hollow cavity, with both ends passing through the two sides of the air-cooled housing. The water-cooled pipes are located above the filter slot. The fan is arranged in the hollow cavity and above the water-cooled pipes.

[0010] A detachable filter element is disposed within the filter slot and located below the water-cooling pipeline.

[0011] Furthermore, the water-cooled pipeline is provided with multiple U-shaped pipes, with the water inlet end of the water-cooled pipeline passing through one side of the air-cooled housing and the water outlet end of the water-cooled pipeline passing through the other side of the air-cooled housing.

[0012] Furthermore, the fan unit includes a fixing plate and a plurality of fans. The fixing plate is disposed in the hollow cavity, and a plurality of fan holes are formed on the fixing plate, with the fans disposed in the fan holes.

[0013] Furthermore, a plurality of first positioning holes are provided on the other side of the air-cooled housing, and second positioning holes are symmetrically provided on the outer side wall of the air-cooled housing. Both the first positioning holes and the second positioning holes are connected to the filter slot.

[0014] Furthermore, the detachable filter element includes a filter plate, a first positioning post, and a deformation fixing part. The first positioning post is provided at one end of the filter plate, and the deformation fixing part is provided at the other end of the filter plate. The deformation fixing part includes a first deformation plate, a second deformation plate, a second positioning post, and an auxiliary guide. One end of the first deformation plate and one end of the second deformation plate are respectively inclinedly provided on both sides of the filter plate. The second positioning post is respectively provided on the outer side wall of the first deformation plate and the second deformation plate, and the second positioning post is close to the filter plate. The auxiliary guide is provided between the first deformation plate and the second deformation plate.

[0015] Furthermore, the auxiliary guide includes a guide post and an auxiliary compression spring. The two ends of the guide post are slidably disposed at the other ends of the first deformation plate and the other ends of the second deformation plate. The auxiliary compression spring is sleeved on the guide post and disposed between the first deformation plate and the second deformation plate. One end of the auxiliary compression spring is fixedly disposed on one side of the first deformation plate, and the other end of the auxiliary compression spring is fixedly disposed on one side of the second deformation plate.

[0016] Preferably, the second positioning post mates with the second positioning hole, and the first positioning post mates with the first positioning hole.

[0017] Furthermore, the dry-type transformer with auxiliary heat dissipation function also includes a fan plate assembly. The top of the air-cooled housing is provided with a fan plate groove, and the fan plate assembly is disposed in the fan plate groove. The fan plate groove is located directly above the fan section. The fan plate assembly includes a mounting fan plate, multiple fan blades, and an adjustment part. The mounting fan plate has a fan blade slot and an adjustment slot. The multiple fan blades are arranged in the fan blade slot, and the adjustment part is disposed in the adjustment slot. The adjustment part controls the multiple fan blades.

[0018] Furthermore, the wind turbine component includes a blade plate and a shaft, the shaft is rotatably disposed in the wind turbine groove, one end of the shaft extends into the adjustment groove, and the blade plate is fixedly disposed on the shaft.

[0019] Furthermore, the adjustment unit includes multiple driven adjustment sprockets, an adjustment rotating column, a main adjustment sprocket, a control chain, and a control wheel.

[0020] Compared with the prior art, a dry-type transformer with auxiliary heat dissipation function according to an embodiment of the present invention includes a dry-type transformer, a line mounting base, a mounting base, a mounting plate, an air-cooled mounting bracket, multiple air-cooling components, and a detachable filter. The air-cooling components are mainly used to cool the dry-type transformer itself. Each air-cooling component includes an air-cooled housing, water-cooled pipes, and a fan. The air-cooled housing has a through-hole hollow cavity, and both the water-cooled pipes and the fan are located within the hollow cavity of the air-cooled housing. The fan is positioned above the water-cooled pipes. When the fan operates, it guides the water-cooled pipes to cool the transformer. The airflow near the water-cooled pipes flows away from the water-cooled pipes. At this time, the airflow undergoes heat exchange through the water-cooled pipes, thereby reducing the temperature of the airflow passing through the water-cooled pipes and forming a low-temperature airflow. The low-temperature airflow is then blown towards the dry-type transformer through the fan section, allowing the low-temperature airflow to come into contact with the surface of the high-temperature dry-type transformer, thereby reducing the surface temperature of the dry-type transformer. Moreover, the temperature of the low-temperature airflow is much lower than the natural outdoor temperature, which improves the cooling efficiency of the dry-type transformer. The detachable filter screen is used to intercept impurities and prevent them from adhering to the water-cooled pipes and the dry-type transformer, while also facilitating installation, disassembly, and subsequent cleaning.

[0035] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0036] like Figure 1-9 As shown in the figure, a dry-type transformer with auxiliary heat dissipation function according to an embodiment of the present invention includes:

[0037] Dry-type transformer, mounting base 1300, line mounting base 1300, 1200, mounting base 1300, mounting base plate 1400, air-cooled mounting bracket 1500, multiple air-cooled components 2000, and removable filter screen 3000;

[0038] The upper end of the dry-type transformer 1100 is provided with a mounting base 1300 and a line mounting base 1300 1200, and the lower end of the dry-type transformer 1100 is provided with a mounting base 1300. Multiple mounting base plates 1400 are provided at the lower part of the mounting base 1300. Air-cooled mounting brackets 1500 are provided on the mounting base plates 1400 and are symmetrically arranged on both sides of the mounting base 1300.

[0039] Multiple air-cooled components 2000 are arranged on the air-cooled mounting bracket 1500. Each air-cooled component 2000 includes an air-cooled housing 2100, water-cooled pipes 2200, and a fan 2300. The air-cooled housing 2100 has a hollow cavity 2110 through it. A filter slot 2120 is opened on one side of the air-cooled housing 2100 and is connected to the hollow cavity 2110. The water-cooled pipes 2200 are arranged inside the hollow cavity 2110 and pass through both sides of the air-cooled housing 2100. The water-cooled pipes 2200 are located above the filter slots 2120. The fan 2300 is arranged inside the hollow cavity 2110 and is located above the water-cooled pipes 2200.

[0040] The removable filter element 3000 is installed in the filter slot 2120 and is located below the water cooling pipe 2200;

[0041] Furthermore, such as Figure 4As shown, the water-cooled piping 2200 is equipped with multiple U-shaped pipes. The water inlet 2210 of the water-cooled piping 2200 passes through one side of the air-cooled housing 2100, and the water outlet 2220 of the water-cooled piping 2200 passes through the other side of the air-cooled housing 2100. After the air-cooled assembly 2000 is installed, a water-cooled circulation assembly needs to be set up to connect the water inlet 2210 and the water outlet 2220 of the water-cooled piping 2200, assisting the water-cooled piping 2200 in forming a flow path, so that the lower temperature water can completely flow through the hollow cavity 2110 of the air-cooled housing 2100. The multiple U-shaped pipes increase the water flow path, so that the airflow contacts the water-cooled piping 2200 to the maximum extent.

[0042] Preferably, the water flow pipeline is made of copper pipe, which has better thermal conductivity and can achieve better temperature exchange.

[0043] Furthermore, such as Figure 3 As shown, the fan unit 2300 includes a fixing plate 2310 and multiple fans 2320. The fixing plate 2310 is disposed in the hollow cavity 2110, and multiple fan holes are formed on the fixing plate 2310. The fans 2320 are disposed in the fan holes. During assembly, the fan unit 2300 is connected to the control circuit. The fans 2320 facilitate airflow, thereby accelerating air exchange.

[0044] When the dry-type transformer 1100 of this utility model with auxiliary heat dissipation function needs to be cooled after long-term use, a water-cooling circulation component is set up. The water-cooling circulation component will continuously pump low-temperature water into the water-cooling pipe 2200. At the same time, the fan 2320 in the fan section 2300 is turned on. The fan 2320 guides air to enter from the bottom of the hollow cavity 2110 of the air-cooled housing 2100, pass through the hollow cavity 2110 of the air-cooled housing 2100, and then blow out from the bottom of the hollow cavity 2110 of the air-cooled housing 2100. First, the airflow passes through the area located in the air-cooled housing. The removable filter 3000 at the bottom of the hollow cavity 2110 of the 2100 intercepts impurities, preventing them from entering the hollow cavity 2110. The airflow then passes through the water-cooling pipe 2200, where it is cooled down. After cooling, the airflow is blown out from the top of the hollow cavity 2110 of the air-cooled housing 2100. The cooled airflow is then blown directly onto the dry-type transformer 1100, which is at a high temperature, thereby reducing the surface temperature of the dry-type transformer 1100, ensuring its service life, and maintaining voltage stability.

[0045] Preferably, the air-cooled mounting bracket 1500 is provided with multiple fixing positions, and the bottom of the air-cooled housing 2100 is set on the fixing positions. A silicone pad is provided between the bottom of the air-cooled housing 2100 and the fixing positions, which helps to buffer the vibration of the air-cooled component 2000 during operation, and at the same time increases the friction between the air-cooled component 2000 and the fixing positions, ensuring that the air-cooled component 2000 is fixed more stably.

[0046] Furthermore, such as Figure 4 As shown, multiple first positioning holes 2130 are opened on the other side of the air-cooled housing 2100, and second positioning holes 2140 are symmetrically opened on the outer side wall of the air-cooled housing 2100. Both the first positioning holes 2130 and the second positioning holes 2140 are connected to the filter slot 2120.

[0047] Furthermore, such as Figure 5As shown, the detachable filter element 3000 includes a filter plate 3100, a first positioning post 3200, and a deformation fixing part. The first positioning post 3200 is provided at one end of the filter plate 3100, and the deformation fixing part is provided at the other end of the filter plate 3100. The deformation fixing part includes a first deformation plate 3310, a second deformation plate 3320, a second positioning post 3330, and an auxiliary guide. One end of the first deformation plate 3310 and one end of the second deformation plate 3320 are respectively inclinedly arranged on both sides of the filter plate 3100. The second positioning post 3330 is respectively arranged on the outer side wall of the first deformation plate 3310 and the second deformation plate 3320. The second positioning post 3330 is close to the filter plate 3100. The auxiliary guide is arranged between the first deformation plate 3310 and the second deformation plate 3320. After prolonged use, the removable filter element 3000 will accumulate a significant amount of impurities and dust on its surface, affecting airflow. The removable filter element 3000 allows for timely cleaning and also makes installation easier. When installing the removable filter element 3000, ensure that one end of the filter plate 3100 first enters the filter slot 2120, so that the first positioning post 3200 at one end of the filter plate 3100 mates with the first positioning hole 2130, completing the initial positioning of the removable filter element 3000. As the filter plate 3100 continues to penetrate deeper into the filter slot 2120, the user simultaneously presses the first positioning post 3200... The first deformation plate 3310 and the second deformation plate 3320 move relative to each other, and at the same time, the first deformation plate 3310 and the second deformation plate 3320 deform. At this time, the second positioning post 3330 on the first deformation plate 3310 and the second deformation plate 3320 enters the filter slot 2120 until the second positioning post 3330 reaches the position of the second positioning hole 2140. Then the user releases the first deformation plate 3310 and the second deformation plate 3320, and the first deformation plate 3310 and the second deformation plate 3320 return to their original state. At this time, the second positioning post 3330 enters the second positioning hole 2140, completing the final positioning of the detachable filter part 3000.

[0048] Furthermore, such as Figure 5The auxiliary guide includes a guide post 3341 and an auxiliary compression spring 3342. The guide post 3341 is slidably positioned at the other ends of the first deformation plate 3310 and the second deformation plate 3320. The auxiliary compression spring 3342 is sleeved on the guide post 3341 and positioned between the first deformation plate 3310 and the second deformation plate 3320. One end of the auxiliary compression spring 3342 is fixedly positioned on one side of the first deformation plate 3310, and the other end is fixedly positioned on one side of the second deformation plate 3320. When the user presses the first deformation plate 3310 and the second deformation plate 3320 relative to each other, the first deformation plate 3310 and the second deformation plate 3320 will slide on the guide post 3341, simultaneously compressing the auxiliary compression spring 3342 between the first deformation plate 3310 and the second deformation plate 3320, facilitating the subsequent return of the first deformation plate 3310 and the second deformation plate 3320 to their initial positions.

[0049] Preferably, the first deformation plate 3310 and the second deformation plate 3320 are made of flexible steel, so that both the first deformation plate 3310 and the second deformation plate 3320 have a certain deformation force.

[0050] Furthermore, such as Figure 6 and Figure 7 As shown, the dry-type transformer with auxiliary heat dissipation function also includes a fan plate assembly 4000. A fan plate groove 2150 is provided on the top of the air-cooled housing 2100. The fan plate assembly 4000 is disposed in the fan plate groove 2150. The fan plate groove 2150 is located directly above the fan section 2300. The fan plate assembly 4000 includes a mounting fan plate 4100, multiple fan blades 4200, and an adjustment section. A fan blade slot 4110 and an adjustment slot 4120 are provided on the mounting fan plate 4100. Multiple fan blades 4200 are arranged in the fan blade slot 4110. The adjustment section is disposed in the adjustment slot 4120. The adjustment section controls the multiple fan blades 4200. As shown in the figure, the cooled airflow cannot be efficiently blown directly onto the dry-type transformer 1100, which increases the cooling time and results in low heat dissipation efficiency. Therefore, the user changes the flow direction of the low-temperature airflow blown out from the top of the hollow cavity 2110 of the air-cooled box 2100 by setting the air plate assembly 4000, so that the low-temperature airflow blows directly onto the dry-type transformer 1100, thereby efficiently reducing the temperature of the dry-type transformer 1100.

[0051] Furthermore, such as Figure 8 As shown, the fan blade assembly 4200 includes a fan blade 4220 and a fan blade shaft 4210. The fan blade shaft 4210 is rotatably mounted in the fan blade slot 4110, with one end extending into the adjustment slot 4120. The fan blade 4220 is fixedly mounted on the fan blade shaft 4210. One end of the fan blade 4220 is provided with a guide angle, and the rotation of the fan blade shaft 4210 will synchronously drive the fan blade 4220 to rotate, changing the angle of the fan blade 4220.

[0052] Furthermore, such as Figure 8 As shown, the adjustment unit includes multiple driven adjustment sprockets 4310, an adjustment rotating column 4320, a main adjustment sprocket 4330, a control chain, and a control wheel 4340. The driven adjustment sprockets 4310 are disposed at one end of the fan blade shaft 4210. The adjustment rotating column 4320 is rotatably disposed at one end of the adjustment groove 4120. The main adjustment sprocket 4330 is disposed on the adjustment rotating column 4320 near the fan blade groove 4110. The control chain drives the main adjustment sprocket 4330 to cooperate with the multiple driven adjustment sprockets 4310. The control wheel 4340 is disposed on the adjustment rotating column 4320 and is located on one side of the main adjustment sprocket 4330. The surface of the control wheel 4340 is decorated with a pattern to increase friction, making it easier for personnel to control the rotation of the control wheel 4340. The rotation of the control wheel 4340 will drive the main adjusting sprocket 4330 on the same adjusting rotating column 4320 to rotate. The rotation of the main adjusting sprocket 4330 will synchronously drive the control chain to rotate, and the control chain will synchronously drive multiple driven adjusting sprockets 4310 to rotate, so that the driven adjusting sprockets 4310 drive the fan blade shaft 4210 to rotate.

[0053] The specific working principle of the wind vane assembly 4000 is as follows: the user controls the control wheel 4340 to rotate counterclockwise, such as... Figure 9 As shown, the control wheel 4340 synchronously drives the main adjusting sprocket 4330 on the adjusting rotating column 4320 to rotate counterclockwise, and at the same time drives the control chain on the main adjusting sprocket 4330 to rotate counterclockwise. The control chain synchronously drives multiple driven adjusting sprockets 4310 to rotate counterclockwise, so that the fan blade shaft 4210 rotates counterclockwise synchronously, and the fan blade 4220 deflects closer to the dry-type transformer 1100. At this time, the airflow with a lower temperature will be guided by the fan blade 4220 to the center of the dry-type transformer 1100, thereby effectively reducing the temperature of the dry-type transformer 1100.
