Description

Technical Field

[0001] The invention relates to the technical field of transformer substations, and in particular to a box-type transformer substation with a heat dissipation function. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation. It is a kind of factory prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines the functions of transformer step-down and low-voltage distribution organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation. Box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution room and distribution station and becomes a new type of complete set of transformer and distribution equipment.

[0003] When the current box-type substation is in use, it is necessary to dissipate heat for the substation box and its internal components. The main reasons for the heating of the box-type substation are internal heating. The main heating component is the transformer. The transformer will produce losses during operation, and these losses will all be converted into heat. There are also external reasons. Since the transformer is installed in an outdoor box and exposed to the sun outdoors, there are currently three main ways to dissipate heat for the box-type substation: opening a heat dissipation port on the outer shell of the box-type substation for natural heat dissipation, which has poor heat dissipation effect on hot days and is not suitable for high temperature seasons and high temperature areas; using fans for forced air cooling for heat dissipation. In high-temperature areas and seasons, the internal air can flow out through internal circulation, but the internal temperature cannot be dissipated, which is not convenient for heat dissipation. The external dust will be easily blown into the box-type substation through the internal and external air replacement, resulting in a large amount of dust adhering to the internal electronic components, affecting the normal use and service life of the electronic components; water cooling is usually used to cool the outer shell of the box-type substation through a heat exchanger. The heat exchange area is small and the heat dissipation is poor. Especially in high-temperature seasons, the sun shines directly on the outer shell of the box-type substation, which will cause the outer shell of the box-type substation to heat up quickly, affecting the effect of water cooling.

[0027] Reference Figure 1 - Figure 8The present invention proposes a box-type substation with heat dissipation function, including a box-type substation shell 1 and a metal top 2, the metal top 2 is fixedly installed on the top of the box-type substation shell 1, the box-type substation shell 1 and the metal top 2 are welded together, and the two are in precise contact, a cement base 3 is fixedly installed at the bottom of the box-type substation shell 1, part of the cement base 3 is buried in the ground, and part of it is exposed above the ground, a cooling water tank 4 is fixedly installed at the bottom of the cement base 3, the cooling water tank 4 is buried underground, and the cooling water tank 4 contains cooling water, and the cooling water tank 4 is buried underground, which can reduce the influence of the cooling water in the cooling water tank 4 on the external temperature, a cooling heat conductive plate 5 is fixedly installed on the back of the box-type substation shell 1, the cooling heat conductive plate 5 is a whole piece of metal plate, and the cooling heat conductive plate 5 is completely attached to the back of the box-type substation shell 1, which can facilitate the heat transfer of the cooling heat conductive plate 5 to the box-type substation shell 1, and a water injection channel 10 is opened in the cooling heat conductive plate 5, and the bottom opening of the water injection channel 10 is connected with a metal water injection pipe 6. The metal water injection pipe 6 penetrates the cement base 3 and extends into the cooling water tank 4 and is inserted into the cooling water. At the same time, a plurality of heat-conducting columns are connected to the bottom of the cooling heat-conducting plate 5. The heat-conducting columns penetrate the cement base 3 and extend into the cooling water for heat transfer. In the non-high temperature season, the sun shines directly on the box-type substation shell 1, causing the temperature of the box-type substation shell 1 to rise. At the same time, the heat generated by the heat generated by the transformer in the box-type substation shell 1 is transferred by the metal water injection pipe 6 to the cooling heat-conducting plate 5. The cooling heat-conducting plate 5 transfers the low temperature to the back of the box-type substation shell 1, dissipates the heat of the box-type substation shell 1 and cools the air in the box-type substation, thereby achieving the heat dissipation effect. Compared with the traditional natural heat dissipation effect, there is no need for other energy loss. A water pump 25 is fixedly installed in the cooling water tank 4. The water inlet of the metal water injection pipe 6 is connected to the water outlet of the water pump 25. A cooling waterfall channel 7 connected to the water injection channel 10 is opened in the metal top 2. The cooling waterfall channel 7 is a cooling water flow channel with a relatively wide width, such as Figure 2As shown in , the cooling water flows over a large area, increasing the contact area between the cooling water and the inner wall of the cooling waterfall channel 7, improving the heat transfer, and increasing the cooling effect. A return water waterfall channel 8 connected to the cooling waterfall channel 7 is opened in the cooling heat conduction plate 5, and the return water waterfall channel 8 is connected to the cooling water tank 4. The width of the return water waterfall channel 8 is the same as the width of the cooling waterfall channel 7. When the cooling water flows from the cooling waterfall channel 7 to the return water waterfall channel 8, a large area of ​​cooling water contacts the inner wall of the return water waterfall channel 8, increasing the contact area between the cooling water and the cooling heat conduction plate 5, improving the heat transfer, and increasing the heat dissipation effect. It should be noted that the number of metal water injection pipes 6 is four, the number of water injection channels 10 is also four, the number of cooling waterfall channels 7 and the number of return water waterfall channels 8 are both two, and the two cooling waterfall channels 7 almost occupy most of the area of ​​the top surface of the metal top 2. The two water injection channels 10 and one cooling waterfall channel 7 are a group, and the two water injection channels 10 are respectively located on both sides of the cooling waterfall channel 7, and the two water injection channels 10 inject cooling water into one cooling waterfall channel 7 at the same time.

[0028] like Figure 1 and Figure 2 As shown, a plurality of movable top plates 9 are rotatably installed on the top surface of the metal roof 2, and a driving structure is installed on the metal roof 2. The driving structure is used to drive the movable top plates 9 to rotate on the top surface of the metal roof 2. When the movable top plates 9 rotate, the flow speed of the air on the top surface of the metal roof 2 can be accelerated. When used in a normal box-type substation, the top surface of the box-type substation remains unchanged. When the sun is directly shining, since the box top of the box-type substation is in a stationary state, the box top will continue to receive sunlight and the temperature will gradually increase. Since the top of the box is stationary, the heat conduction rate inside the top of the box is slow, so the temperature of the top of the box will rise slowly. In addition, the heat dissipation rate on the surface of the top of the box is also slow, because there is no air flow to accelerate the convection dissipation of heat. Therefore, the top of the box will gradually become hotter when it is stationary; when the top of the box becomes rotating, the top of the box is in a rotating state, the top of the box will constantly move and drive the surrounding air flow. This air flow will promote the convection dissipation of heat, so that the heat will be dissipated from the surface of the top of the box to the surrounding environment faster. Therefore, it is easier for the top of the box to dissipate heat when it is rotating than when it is not moving, and the surface temperature will be relatively low. In addition, when the top of the box rotates, different parts will alternately receive sunlight, making the heat distribution more even and not easy to overheat locally. In general, it is easier for the top of the box to dissipate heat when it is rotating than when it is not moving, and the surface temperature is relatively low. Therefore, under the sun, in order to keep the temperature of the top of the box suitable, the top of the box can be kept running to help dissipate heat and lower the overall temperature.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the driving structure includes an impeller 11, a driving gear 12 and a transmission gear 13; a driving channel 14 connecting the water injection channel 10 and the cooling waterfall channel 7 is opened in the metal top 2, and a rotating groove is opened on the inner wall of the driving channel 14. The impeller 11 is rotatably installed in the driving channel 14, and part of the blades of the impeller 11 are located in the driving channel 14. The water pump 25 works to inject cooling water into the water injection channel 10 through the metal water injection pipe 6, and the cooling heat conduction plate 5 transfers the temperature of the cooling water to the back of the box-type substation shell 1, and then cools down the hot air in the box-type substation. The cooling water then enters the driving channel 14. Since part of the blades of the impeller 11 are located in the driving channel 14, the flowing cooling water drives the impeller 11 to rotate, and the rotating impeller 11 drives the driving gear 12 to rotate synchronously. Since the driving gear 12 and the transmission gear 13 are meshed, the driving gear 12 drives the transmission gear 13 to rotate, and then the transmission gear 13 is driven by the driving gear 12. The gear 13 drives the movable top plate 9 to rotate, so that all parts of the movable top plate 9 are evenly exposed to the sun. During the rotation of the movable top plate 9, the air on the top surface of the metal top 2 is driven to flow rapidly, and the flowing air accelerates the heat dissipation, thereby reducing the temperature of the metal top 2 and reducing the temperature impact on the box-type substation shell 1. A transmission groove is opened in the metal top 2, and the driving gear 12 rotates in the transmission groove. The impeller 11 and the driving gear 12 are fixedly connected through a transmission shaft. The impeller 11 and the driving gear 12 are coaxially arranged. The transmission gear 13 is rotatably installed in the transmission groove, and the transmission gear 13 is meshed with the driving gear 12. The transmission gear 13 is fixedly connected to the rotation of the movable top plate 9. In normal temperature weather, the temperature in the box-type substation can be heat-conducted by the metal water injection pipe 6. The heat dissipation of the box-type substation shell 1 can be achieved by reducing the temperature of the box-type substation shell 1. No water cooling is required, which can save electricity and reduce energy waste.

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the bottom inner wall of the cooling waterfall channel 7 is inclined downward toward the back side of the box-type substation shell 1. When the cooling water reaches the driving channel 14, it enters the cooling waterfall channel 7 horizontally. The cooling water flows downward along the bottom inner wall surface of the cooling waterfall channel 7 under the action of gravity, and the metal top 2 is cooled and dissipated by the cooling water. The cooling water flows along the inclined inner wall of the cooling waterfall channel 7 to the return water waterfall channel 8. The cooling water flows along the inner wall of the return water waterfall channel 8 and cools and dissipates the back shell of the box-type substation shell 1. At the same time, the hot air in the box-type substation shell 1 is cooled and dissipated. Since the cooling water can contact the inner wall of the cooling waterfall channel 7 and the inner wall of the return water waterfall channel 8 over a large area, the heat conduction area is increased, the heat transfer is increased, and the cooling and heat dissipation effect is improved.

[0031] like Figure 2 , Figure 3and Figure 4 As shown, a plurality of dividing strips 15 are fixedly connected to the bottom inner wall of the cooling waterfall channel 7, and the length direction of the dividing strips 15 is consistent with the water flow direction in the cooling waterfall channel 7. The plurality of dividing strips 15 can divide the cooling waterfall channel 7 into a plurality of cooling channels. After the cooling water enters the cooling waterfall channel 7 horizontally, the cooling water is affected by gravity and flows down flatly. The dividing strips 15 divide the water into a plurality of strips, thereby reducing the occurrence of water flows converging into bundles and flowing down, thereby ensuring the contact area between the cooling water and the inner wall of the cooling waterfall channel 7 in the cooling waterfall channel 7. The length of the dividing strips 15 can be designed to be different in length according to actual conditions. The end of the dividing strips 15 gradually rises in a step-like manner from the side of the cooling waterfall channel 7 to the middle. Each time the cooling water passes through a dividing strip 15, part of the cooling water will be intercepted and enter the cooling channel at the corresponding position, so that the cooling water can be evenly distributed in the cooling waterfall channel 7, thereby increasing the contact area with the cooling water and improving the heat transfer.

[0032] like Figure 1 and Figure 2 As shown, a top inclined groove 16 is provided on the top surface of the metal roof 2, and a plurality of movable top panels 9 are rotated at the top opening of the top inclined groove 16 through a rotating shaft, which can ensure the rotation of the movable top panels 9. On rainy days, rainwater can flow backwards to reduce the accumulation of rain on the metal roof 2.

[0033] like Figure 2 As shown, an L-shaped pipe 17 is fixedly installed on the bottom surface of the metal roof 2, and the L-shaped pipe 17 is located at the top of the box-type substation shell 1. A circulation fan 18 is installed in the L-shaped pipe 17. The air inlet of the L-shaped pipe 17 is located at the top of the box-type substation shell 1 near the front end of the box-type substation shell 1, and the air outlet of the L-shaped pipe 17 faces the back inner wall of the box-type substation shell 1. When the box-type substation shell 1 needs to be cooled and dissipated, the hot air inside the box-type substation shell 1 moves upward, and the circulation fan 18 works to blow the hot air from the top front position inside the box-type substation shell 1 The air is sucked into the L-shaped pipe 17, and the hot air contacts the bottom surface of the metal roof 2 for cooling and heat dissipation. The cooled hot air is then blown to the back shell of the cooled box-type substation shell 1 for cooling again. The cooled air continues to move downward and replaces the air at the bottom. The air at the bottom is replaced and rises, so that the air inside the box-type substation shell 1 forms a circulation, which can make the hot air in the box-type substation shell 1 be cooled and dissipated in a better and orderly manner, so that the air cooling and heat dissipation effect inside the box-type substation shell 1 is better.

[0034] like Figure 2 and Figure 8As shown, a heat-conducting rod 19 is fixedly installed at the bottom of the metal top 2, and a plurality of heat-conducting wires 20 are circumferentially connected to the outer periphery of the heat-conducting rod 19, and the heat-conducting rod 19 and the heat-conducting wires 20 are both located in the L-shaped pipe 17. When the hot air enters the L-shaped pipe 17, the contact area with the hot air can be increased, thereby increasing the cooling effect on the hot air.

[0035] like Figure 2 and Figure 3 As shown, the inner wall of the return water waterfall channel 8 is fixedly installed with an inclined guide plate 21, and there is a distance between the guide plate 21 and the inner wall of the return water waterfall channel 8 on the side close to the box-type substation shell 1, and the guide plate 21 is arranged downwardly and inclined toward the side close to the box-type substation shell 1. When the cooling water flows from the cooling waterfall channel 7 to the return water waterfall channel 8, part of the cooling water will be in the middle position of the return water waterfall channel 8 and will not contact the inner wall of the return water waterfall channel 8. Due to the design of the guide plate 21, the cooling water flows onto the guide plate 21, and the cooling water flows downward along the inclined surface of the guide plate 21, so that the cooling water can contact the cooling heat conduction plate 5. By making the cooling water flow in a waterfall-like manner and increasing the contact area, the heat can be better transferred to the cooling water and taken away.

[0036] like Figure 2 and Figure 3 As shown, the inner wall of the return water waterfall channel 8 close to the box-type substation shell 1 is arranged inclined, and the inner wall of the return water waterfall channel 8 can be regarded as a slope. When the cooling water flows from the cooling waterfall channel 7 to the return water waterfall channel 8, more cooling water can flow along the slope, which can facilitate the cooling water to take away more heat; the bottom of the return water waterfall channel 8 is connected with a return water pipe 22, and the return water pipe 22 passes through the cement base 3 and is connected with the cooling water tank 4. A floor drain core is detachably installed in the return water pipe 22, and the floor drain core can ensure the unidirectional flow of water. The design of the return water pipe 22 is to slow down the speed of the cooling water when it returns, so that part of the cooling water can remain at the bottom of the return water waterfall channel 8, and will not all flow back to the cooling water tank 4 at once, thereby increasing the contact area of ​​the cooling water, which can better cool and dissipate the heat of the box-type substation shell 1. Effect, and the metal roof 2 and the back of the box-type substation shell are equivalent to a double-layer structure. In high temperature seasons, the sun shines directly, the outermost layer of the shell absorbs heat, and heat is transferred through the connected positions on both sides. However, due to the small contact area, the transferred heat is less, and part of the heat needs to be transferred through the air and cooling water in the cooling waterfall channel 7 and the return water waterfall channel 8. However, since the cooling water is flowing, the heat can be quickly absorbed and taken away. In addition, the connection positions on both sides of the shell have a small contact area. When the cooling water flows, the contact positions can also be quickly cooled and dissipated, which can reduce the heat conduction and make the cooling and heat dissipation effect better. The top surface of the metal roof 2 is still composed of a plurality of rotating movable top plates 9, which makes the temperature rise smaller, which is more conducive to the cooling and heat dissipation effect.

[0037] like Figure 1 and Figure 2 As shown, a cooling plate 23 is fixedly installed in the cooling water tank 4, and the cooling plate 23 is immersed in cooling water. A heat-conducting column 24 is fixedly connected to the bottom of the cooling water tank 4. The top of the heat-conducting column 24 passes through the cooling water tank 4 and is fixedly connected to the bottom surface of the cooling plate 23. The cooling water transfers the temperature to the cooling plate 23, and the cooling plate 23 transfers the temperature to the heat-conducting column 24, and the heat-conducting column 24 transfers the heat to the soil. In the high temperature season, the temperature of the soil 3-5 meters underground is about 15-20 degrees Celsius, which can be several tens of degrees different from the temperature of the box-type substation shell 1 exposed to direct sunlight. It can be completely heat-dissipated, and there is no need for additional refrigeration equipment to refrigerate the cooling water, which can save a lot of energy. In addition, the cooling water tank 4 itself can also transfer heat to dissipate heat, which is completely sufficient to cool the cooling water itself.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
