Description

TECHNICAL FIELD

[0001] The present application relates to the field of box-type substations, in particular to a 10KV substation noise reduction and heat dissipation structure. BACKGROUND

[0002] The 10KV substation refers to a place in the power system for transforming voltage and current, receiving and distributing electric energy.

[0003] The 10KV substation usually includes a box body and various electrical elements arranged in the box body. During use, heat is continuously generated inside the substation. Excessive heat can cause overheating of internal electrical elements, leading to short circuit and even fire. The current heat dissipation method for substations usually uses fans and exhaust holes to discharge heat.

[0004] However, the demand for heat dissipation is different in different environments. In hot and dry environments, the heat dissipation effect needs to be increased. In cold and humid environments, the heat dissipation effect needs to be reduced, and the internal heat can ensure that the substation is in a dry state.

[0005] Therefore, the current heat dissipation method cannot meet the heat dissipation needs of different environments, and there is room for improvement. SUMMARY

[0006] In order to realize the adjustment of the heat dissipation effect and adapt to the heat dissipation needs of different environments, the present application provides a 10KV substation noise reduction and heat dissipation structure.

[0007] The 10KV substation noise reduction and heat dissipation structure provided by the present application adopts the following technical scheme:

[0008] A 10KV substation noise reduction and heat dissipation structure includes a box body, an installation space for installing electrical elements is formed in the box body, and a soundproof board is arranged on the inner wall of the box body. An air inlet and an air outlet are formed on the side wall of the box body, and a heat dissipation fan is installed at the air outlet of the box body. A damper plate is rotatably arranged on the inner wall of the box body, a communication port is formed on the damper plate and communicates with the air outlet, two communication ports are arranged, and the sizes of the two communication ports are different.

[0009] By driving the damper plate to rotate, the communication ports of different sizes are communicated with the air outlet, the cross-sectional area of the air outlet is changed, the air outlet effect is changed, the heat dissipation effect is changed, the larger communication port is communicated with the air outlet in hot and dry environments, the smaller communication port is communicated with the air outlet in cold and humid environments, and the heat dissipation needs of different environments are met, so the adaptability is stronger.

[0010] Preferably, the box is provided with a cooling channel, one end of the cooling channel is communicated with an external water tank, the other end of the cooling channel is communicated with the water tank, and the box is provided with an adjusting assembly for controlling the flow of the cooling channel.

[0011] Through the above technical scheme, during the operation of the transformer substation, the cooling water circulates in the cooling channel to exchange heat with the heat in the box, thereby achieving the cooling of the transformer substation. Since the cooling channel is filled with water, the internal noise can be isolated to some extent, thereby achieving the noise reduction effect.

[0012] Preferably, the box is provided with an expanding portion on one side of the cooling channel, the adjusting assembly comprises an adjusting plate and a linkage plate, the adjusting plate is slidingly arranged in the expanding portion, the linkage plate is fixedly connected with the adjusting plate, and the box is provided with a driving member for driving the linkage plate to slide.

[0014] Preferably, the driving member is the air adjusting plate, the air adjusting plate is in a rectangular shape, the expanding portion is provided with a return spring, one end of the return spring is connected with the inner wall of the expanding portion, and the other end of the return spring is connected with the adjusting plate; the inner wall of the box is provided with a sliding groove for the linkage plate to slide; the linkage plate is provided with a first sliding groove, the linkage plate is slidingly connected with a first wedge-shaped block in the first sliding groove, the first wedge-shaped block extends out of the sliding groove, the first wedge-shaped block is provided with a first wedge-shaped surface, the first sliding groove is provided with a first compression spring, one end of the first compression spring is connected with the inner wall of the first sliding groove, and the other end of the first compression spring is connected with the first wedge-shaped block.

[0015] By adopting the above technical solution, during the rotation of the air regulating plate, the surface of the air regulating plate is always in contact with the first wedge surface of the first wedge block. The first wedge block slides into the second sliding groove. When the first wedge block enters the connecting port, it resets. Then, the edge of the connecting port contacts the side of the first wedge block and drives the first wedge block to slide. At this time, the linkage plate slides in the sliding groove, and the linkage plate synchronously drives the adjustment plate to slide, thereby adjusting the cross-sectional area of ​​the cooling channel, changing the flow rate and flow of the cooling water, and thus adjusting the cooling effect. Moreover, when connecting ports of different sizes cooperate with the first wedge block, the linkage plate moves different distances. When the larger connecting port cooperates with the first wedge block, the linkage plate moves a smaller distance, that is, the cooling effect is reduced. At this time, the smaller connecting port is connected to the exhaust port, and the heat dissipation effect is also reduced. Conversely, when the smaller connecting port cooperates with the first wedge block, the linkage plate moves a larger distance, the cooling effect is improved, and the larger connecting port is connected to the exhaust port.

DETAILED DESCRIPTION

[0038] The following is combined with Figures 1-8 This application is described in further detail.

[0039] The embodiment of the present application discloses a noise reduction and heat dissipation structure for a 10KV substation.

[0040] Example 1

[0041] Reference Figure 1The noise reduction and heat dissipation structure of the 10KV substation includes a box body 1, a plurality of dampers 11 are installed at the bottom of the box body 1, and a mounting plate 12 is installed on all the dampers 11. The box body 1 is located above the mounting plate 12 to form an installation space 13, and the electrical components are installed in the installation space 13. The inner wall of the box body 1 is provided with a sound insulation board for noise reduction, and the sound insulation board is a porous structure; an air inlet 2 and an air exhaust port 3 are provided on one side wall of the box body 1, and a filter plate 21 is installed at the air inlet 2 to prevent impurities from entering the substation, and a cooling fan 31 is installed at the air exhaust port 3 of the box body 1; an air regulating plate 4 is rotatably provided on the inner wall of the box body 1, and the rotation axis of the air regulating plate 4 is located above the air exhaust port 3. The air regulating plate 4 is rectangular, and two connecting ports 41 are provided on the air regulating plate 4. The two connecting ports 41 are of different sizes, and the centers of the two connecting ports 41 are symmetrical about the rotation axis of the air regulating plate 4.

[0042] By driving the air regulating plate 4 to rotate, the connecting ports 41 of different sizes can be aligned and connected with the exhaust port 3, thereby changing the flow area of ​​the exhaust port 3. The change in the exhaust cross-sectional area directly affects the exhaust effect, thereby adjusting the heat dissipation efficiency. Specifically, the larger connecting port 41 is selected to be connected to the exhaust port 3 to increase the exhaust cross-sectional area, increase the exhaust volume, and improve the heat dissipation effect. Switching to a smaller connecting port 41 to be connected to the exhaust port 3 reduces the exhaust cross-sectional area and reduces the exhaust volume, thereby avoiding excessive heat dissipation that causes humidity inside the substation and affects the normal operation of electrical components. That is, by adjusting the heat dissipation efficiency through the air regulating plate 4, it can adapt to the heat dissipation requirements of different environments and has greater applicability.

[0043] A cooling channel 5 is defined within the housing 1. The water inlet of the cooling channel 5 is located on the upper side of the housing 1, and the cooling channel 5 circulates around the housing 1. The water outlet of the cooling channel 5 is located on the lower side of the housing 1. In practice, the water inlet and outlet of the cooling pipe are both connected to an external water tank, and circulation is achieved through pumping. A regulating assembly 6 is also mounted on the housing 1 to control the flow rate of the cooling channel 5.

[0044] During substation operation, cooling water continuously circulates within cooling channel 5, exchanging heat with the heat within enclosure 1 to cool the substation interior. Furthermore, since cooling channel 5 is filled with water, its high density can effectively block noise generated by equipment operation, thereby achieving a noise reduction effect.

[0045] Reference Figure 1 、 Figure 2 and Figure 3A flared portion 51 is formed on the water inlet side of the cooling channel 5 of the box body 1. The adjustment assembly 6 includes an adjustment plate 61 and a linkage plate 62. The adjustment plate 61 slides in the flared portion 51. The linkage plate 62 and the adjustment plate 61 are fixedly connected by a vertical rod 63. A return spring 52 is provided in the flared portion 51. One end of the return spring 52 is connected to the inner wall of the flared portion 51, and the other end is fixedly connected to the adjustment plate 61. A driving member for driving the linkage plate 62 to slide is provided in the box body 1.

[0046] Reference Figure 1 、 Figure 3 and Figure 4 In this application, the driving member is set as the air regulating plate 4, and the inner wall of the box body 1 is provided with a sliding groove 14 for the sliding of the linkage plate 62. The linkage plate 62 is formed with a first sliding groove 7, and a first wedge block 71 is slidingly connected in the first sliding groove 7. The first wedge block 71 extends out of the sliding groove 14, and a first wedge surface 711 is formed on the first wedge block 71. A first compression spring 72 is provided in the first sliding groove 7, and one end of the first compression spring 72 is connected to the inner wall of the first sliding groove 7, and the other end is connected to the first wedge block 71.

[0047] A second sliding groove 8 is defined within the linkage plate 62, into which a telescopic block 81 is slidably connected. The first sliding groove 7 is defined within the telescopic block 81, and a second compression spring 82 is disposed within the second sliding groove 8. One end of the second compression spring 82 is connected to the inner wall of the second sliding groove 8, and the other end is connected to the telescopic block 81. A second wedge block 9 is also fixedly connected to the end of the sliding groove 14. A second wedge surface 91 is formed on the second wedge block 9. A through groove 811 is defined in the middle of the telescopic block 81, and a third wedge surface 812 is formed on the inner wall of the through groove 811, which mates with the second wedge surface 91.

[0048] During the rotation of the air regulating plate 4, its surface is always in contact with the first wedge surface 711 of the first wedge block 71. Under the guidance of the wedge surface, the first wedge block 71 is in a compressed state. When the first wedge block 71 completely enters the connecting port 41, it automatically resets under the action of the first compression spring 72. Subsequently, the edge of the connecting port 41 abuts against the side of the first wedge block 71, pushing the first wedge block 71 to continue sliding. At this time, the linkage plate 62 moves synchronously in the sliding groove 14, and drives the adjustment plate 61 to slide, thereby realizing the adjustment of the cross-sectional area of ​​the cooling channel 5. By changing the cross-sectional area of ​​the cooling channel 5, the flow rate and flow of the cooling water can be controlled, and the cooling effect can be adjusted. Refer to Figure 5When the smaller connection port 41 is connected to the exhaust port 3, the heat dissipation efficiency decreases, and the larger connection port 41 drives the adjustment plate 61 to move a smaller distance. That is, the cooling channel 5 opens a smaller gap, the water flow rate is smaller, and the cooling effect decreases simultaneously. Conversely, when the larger connection port 41 is connected to the exhaust port 3, the heat dissipation efficiency increases, and the smaller connection port 41 drives the linkage plate 62 to move a larger distance. The cooling channel opens a larger gap, the water flow rate increases, and the cooling effect improves simultaneously. This linkage design achieves synchronous adjustment of the cooling system and the heat dissipation system through the coordinated action of the air adjustment plate 4, the first wedge block 71, the linkage plate 62, and the adjustment plate 61, so as to synchronously adapt to the heat dissipation requirements of different environments.

[0049] As the air damper plate 4 rotates, the edge of the communication opening 41 first pushes the linkage plate 62 to continue sliding along the sliding groove 14. After the linkage plate 62 has slid a certain distance, the third wedge block engages with the penetration groove 811. At this point, the inclined guiding action of the second wedge surface 91 and the third wedge surface 812 takes effect, driving the telescopic block 81 to retract into the second sliding groove 8, thereby driving the first wedge block 71 to slide synchronously, gradually disengaging the communication opening 41.

[0050] When the first wedge 71 is completely separated from the connecting port 41, the return spring 52 releases its elastic potential energy, pushing the linkage plate 62 back along the sliding slot 14. At this point, the linkage mechanism completes one adjustment cycle and is ready for switching with the next connecting port 41. This process enables orderly switching between connecting ports 41 of different sizes, ensuring coordinated adjustment of the cross-sectional area of ​​the cooling channel 5 and the exhaust cross-sectional area.

[0051] Reference Figure 1 A rotating shaft is coaxially fixed to the middle of the air regulating plate 4, and the rotating shaft rotates with the inner wall of the box body 1. The rotating shaft passes through the outside of the box body 1, and a rotating motor 15 is installed on the outer wall of the box body 1. The output shaft of the rotating motor 15 is coaxially fixed with the rotating shaft, and the rotating motor 15 drives the air regulating plate 4 to rotate 180 degrees.

[0052] The implementation principle of a noise reduction and heat dissipation structure of a 10KV substation in an embodiment of the present application is as follows: during operation of the substation, if it is in a hot and dry environment, the air regulating plate 4 is controlled to rotate so that the larger connecting port 41 is connected to the exhaust port 3, thereby improving the heat dissipation efficiency. At this time, with the cooperation of the smaller connecting port 41 and the first wedge block 71, the regulating plate 61 slides a larger distance, and the flow rate of the cooling channel 5 increases, that is, the heat dissipation effect and the cooling effect are simultaneously improved; on the contrary, in a cold and humid environment, the regulating plate 61 rotates, the smaller connecting port 41 is connected to the exhaust port 3, and the heat dissipation efficiency decreases. At this time, with the cooperation of the larger connecting port 41 and the first wedge block 71, the regulating plate 61 slides a smaller distance, and the flow rate of the cooling channel 5 decreases, that is, the heat dissipation effect and the cooling effect are simultaneously reduced. Through the above-mentioned linkage method, the heat dissipation effect and the cooling effect are synchronously adjusted, which helps to adapt to the heat dissipation needs in different environments.

[0053] Example 2

[0054] Reference Figure 6 、 Figure 7 and Figure 8 The difference between this embodiment and embodiment 1 is that a lifting groove 16 is opened on the upper side of the box body 1 at the air inlet 2, the filter plate 21 is lifted and slid in the lifting groove 16 along the vertical direction, and an inclined dust scraping portion 211 is formed on the upper top wall of the air inlet 2, and a driving component 10 for driving the filter plate 21 to rise and fall is provided on the box body 1.

[0055] The drive assembly 10 includes a connecting rope 101, a movable pulley 102, and a slider 103 that slides vertically. One end of the connecting rope 101 is fixedly connected to the top wall of the lifting groove 16, and the other end of the connecting rope 101 is fixedly connected to the slider 103. The connecting rope 101 is wound around the movable pulley 102, and the rotating axis of the movable pulley 102 forms a vertical guide with the inner wall of the lifting groove 16. The movable pulley 102 is fixedly connected to the filter plate 21 via a connecting rod. A slide groove 20 is formed in the vertical direction on one side of the casing 1 located in the lifting groove 16, and the slider 103 slides in the slide groove 20.

[0056] When the air regulating plate 4 rotates, the side of the air regulating plate 4 will drive the slider 103 to slide upward in the slide groove 20, and drive the movable pulley 102 to slide upward through the connecting rope 101, thereby driving the filter plate 21 to rise. When the filter plate 21 rises, the dust and impurities on the surface of the filter plate 21 will be scraped off by the dust scraping part 211 to prevent impurities from clogging the filter plate 21 and affecting the air intake effect; and then, the slider 103 is separated from the air regulating plate 4, and under the action of gravity of the filter plate 21, the slider 103 descends, and the filter plate 21 is reset. When the filter is reset due to gravity, it will also collide with the lower bottom wall of the air inlet 2, and the surface will be cleaned again by vibration force to improve the impurity removal effect.

[0057] In practice, when the air regulating plate 4 drives the filter plate 21 to rise, the surface of the air regulating plate 4 will block the exhaust port 3. At this time, the exhaust effect in the substation is reduced to a minimum, preventing the exhaust effect from occurring when the filter plate 21 rises, causing impurities falling from the filter plate 21 to be sucked into the substation.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
