[0002] In recent years, with economic development and rapid social progress, the number of complete power distribution facilities in cities has continued to increase. Packaged substations are one such type of urban power distribution facility. Packaged substations are prefabricated, compact indoor and outdoor power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a specific wiring scheme. Suitable for urban power grid construction and renovation, packaged substations represent a new type of substation, following the rise of civil substations. Packaged substations are suitable for mines, factories, enterprises, oil and gas fields, and wind power stations. They replace existing civil distribution rooms and substations, becoming a new type of complete power distribution and transformation system. Packaged substations are mostly installed outdoors for ease of use.

[0011] The U-shaped tube is fixedly installed on the inner wall of the transformer box near the box door, and the edge of the heat conducting plate is fixed to the inner wall of the transformer box.

[0012] Preferably, the heat conducting plates are evenly distributed on the outer circumferential surface of the heat conducting tube, the heat conducting plates are vertically installed, and the notches are evenly opened on the surface of the heat conducting plates.

[0013] By utilizing the suction force of the suction fan and combining the connection between the right-angle air duct, the square connecting tube and the U-shaped tube, the gas in the heat-conducting pipe enters the U-shaped tube under the action of suction, and is transported by the right-angle air duct and the square connecting tube and discharged through the air outlet of the suction fan, so that the gas in the heat-conducting pipe and the U-shaped tube can circulate. Through the flow of gas, the heat can be quickly taken out and the heat in the transformer box can be quickly dissipated.

[0014] Preferably, the heat conducting pipes are evenly installed in the middle of the surface of the U-shaped pipe, and the heat conducting plates are fixedly connected to the heat conducting pipes.

[0015] Preferably, a supporting assembly is installed at the bottom of the transformer box cavity and near the position of the intubation, and the supporting assembly includes a square base, the bottom of the square base is fixedly connected to the bottom of the transformer box cavity, the top of the square base is fixedly connected to a flat plate, and a square mounting piece is fixedly installed in the middle of the top of the flat plate, the surface of the transformer and near the top position are fixed to the square mounting piece by screws, the top of the flat plate and near the position of the intubation is fixedly connected to a positioning cylinder, the top of the positioning cylinder is fixedly connected to a sealing ring, the bottom end of the intubation passes through the center of the sealing ring, and the bottom end of the intubation extends to the inside of the positioning cylinder, and air holes are opened in the inside of the flat plate and near the square mounting piece and the positioning cylinder. The transformer is installed on the top of the square mounting piece and is supported by the square base, so that the flat plate separates the transformer from the bottom of the transformer box cavity, and the bottom of the flat plate is suspended between the bottom of the transformer box cavity to form a suspended layer, which can play a moisture-proof effect and make the transformer less likely to get damp.

[0016] Preferably, the positioning cylinders are evenly distributed on the top of the flat plate, and the positions of the positioning cylinders correspond to the positions of the cannulas, and the sealing rings are made of rubber.

[0017] The bottom end of the insert tube passes through the center of the sealing ring and extends to the inside of the positioning cylinder. The sealing ring can be sealed to prevent gas leakage. As the gas in the heat pipe is discharged, the insert tube draws air from the inside of the positioning cylinder, so that the gas in the air hole is sucked out. The air inlet of the air hole is opened below the transformer, and the air holes are evenly opened inside the flat plate, so that the hot air around the transformer can be sucked out, so that the heat dissipation is uniform and dead corners are less likely to occur.

[0020] Preferably, the tension spring is installed in the middle of the air outlet of the right-angle exhaust duct, and the surface of the rubber ring fits with the inner wall of the air outlet of the right-angle exhaust duct. When the heat dissipation in the transformer box is completed, the suction fan stops working, so that the power of the wind blowing on the sealing ball disappears, and under the elastic tension of the tension spring, the sealing ball drives the rubber ring to move upward, and the surface of the rubber ring fits with the inner wall of the air outlet of the right-angle exhaust duct, so that the air outlet of the right-angle exhaust duct can be sealed, and external dust and impurities are not easily entered into the interior of the right-angle exhaust duct.

[0021] The present invention provides a box-type substation with an arrayed low-voltage heat dissipation structure. It has the following beneficial effects:

[0022] 1. This box-type substation with an arranged low-voltage heat dissipation structure can transfer the heat inside the transformer box to the heat pipes through the heat transfer principle and the heat conduction of the heat conducting sheets. The heat pipes are evenly installed on the surface of the U-shaped tubes, and the heat conducting sheets are evenly installed on the surface of the heat conducting tubes. The heat pipes and heat conducting sheets form an arranged heat dissipation mechanism, which can improve the heat transfer efficiency and promote the conduction of heat inside the transformer box.

[0023] 2. The box-type substation with an arranged low-voltage heat dissipation structure uses a U-shaped tube to be fixed on the inner wall of the transformer box and close to the box door, and the edge of the heat conducting plate is fixed to the inner wall of the transformer box, and the U-shaped tube and the heat conducting plate are fixed together to form an integrated type, which can support the inner wall of the transformer box, thereby increasing the condition of the transformer box itself, making it less likely to deform and having an anti-collision effect.

[0024] 3. The box-type substation with an arranged low-voltage heat dissipation structure utilizes the suction force of the suction fan and combines the connection between the right-angle air duct, the square connecting tube and the U-shaped tube, so that the gas in the heat-conducting pipe enters the U-shaped tube under the action of suction, and is transported by the right-angle air duct and the square connecting tube and discharged through the air outlet of the suction fan, so that the gas in the heat-conducting pipe and the U-shaped tube circulates. The heat can be quickly taken out through the flow of gas, and the heat in the transformer box can be quickly dissipated.

[0025] 4. This box-type substation with an arranged low-voltage heat dissipation structure has a blowing force on the triangular bucket as the gas in the square connecting tube flows. Under the blowing of the airflow, the connecting teeth and the triangular bucket rotate together to adjust the angle, and the elastic membrane can be pulled by the bottom end of the connecting teeth to cause the elastic membrane to deform elastically. By making the elastic membrane concave toward the inside of the square connecting tube, the cross-sectional area of ​​the inner cavity of the square connecting tube can be reduced, thereby increasing the gas flow rate and further accelerating the dissipation of heat.

[0026] 5. The box-type substation with an arranged low-voltage heat dissipation structure, supported by a square base, uses a flat plate to separate the transformer from the bottom of the transformer box cavity, and the bottom of the flat plate and the bottom of the transformer box cavity are suspended to form a suspended layer, which can achieve a moisture-proof effect and prevent the transformer from getting damp.

[0027] 6. The box-type substation with an arranged low-voltage heat dissipation structure passes through the center of the sealing ring through the bottom end of the insert and extends to the inside of the positioning cylinder. The sealing ring can be sealed, and gas leakage is not likely to occur. As the gas in the heat pipe is discharged, the insert draws air from the inside of the positioning cylinder, so that the gas in the air hole is sucked out, and the air inlet of the air hole is opened below the transformer, and the air holes are evenly opened inside the flat plate, so that the hot air around the transformer can be sucked out, so that the heat dissipation is uniform and dead corners are not likely to occur.

[0028] 7. The box-type substation with an arranged low-voltage heat dissipation structure discharges gas through the air outlet of the suction fan, allowing the gas to enter the right-angle exhaust duct. The gas can then apply blowing force to the blocking ball, causing the blocking ball to move downward. The blocking ball applies tension to the tension spring, which elastically deforms. The blocking ball is moved out of the air outlet of the right-angle exhaust duct, allowing smooth exhaust.

[0029] 8. The box-type substation with an arranged low-voltage heat dissipation structure uses the suction fan to stop working, so that the wind power of the sealing ball disappears, and under the elastic tension of the tension spring, the sealing ball drives the rubber ring to move upward, and uses the surface of the rubber ring to fit with the inner wall of the air outlet of the right-angle exhaust duct, so that the air outlet of the right-angle exhaust duct can be sealed, and external dust and impurities are not easy to enter the interior of the right-angle exhaust duct.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0041] The first embodiment, as Figures 1 to 6As shown, the present invention provides a technical solution:

[0042] A box-type substation with an arranged low-voltage heat dissipation structure includes a transformer box 1 and a transformer 2. The transformer 2 is installed in the middle of the transformer box 1. A box door 3 is installed in the middle of the surface of the transformer box 1.

[0043] The heat dissipation mechanism 4 is used to cool the interior of the transformer box 1. The heat dissipation mechanism 4 is installed inside the transformer box 1 and close to the transformer 2.

[0044] Among them, the heat dissipation mechanism 4 includes an arranged heat conductor 41 and a suction fan 42. The arranged heat conductor 41 is installed inside the transformer box 1 and close to the inner wall. The suction fan 42 is fixedly installed in the middle of the top of the transformer box 1. The air inlet of the suction fan 42 is connected with a right-angle air duct 43. The bottom end of the right-angle air duct 43 is connected with a square connecting tube 44. An elastic membrane 45 is fixedly installed at the bend of the surface of the square connecting tube 44. A connecting tooth 46 is hinged on the inner wall of the square connecting tube 44 and close to the elastic membrane 45. The bottom end of the connecting tooth 46 is connected to the surface of the elastic membrane 45. The top of the connecting tooth 46 is fixedly connected with a triangular bucket 47. As the gas in the square connecting tube 44 flows, the airflow exerts a blowing force on the triangular bucket 47. Under the blowing of the airflow, the connecting tooth 46 and the triangular bucket 47 rotate together to adjust the angle. The elastic membrane 45 can be pulled by the bottom end of the connecting tooth 46, so that the elastic membrane 45 is elastically deformed. By making the elastic membrane 45 concave toward the inside of the square connecting tube 44, the cross-sectional area of ​​the inner cavity of the square connecting tube 44 can be reduced, thereby increasing the gas flow rate and further accelerating the heat dissipation.

[0045] The surface of the elastic membrane 45 is wavy. There are two elastic membranes 45 , and the two elastic membranes 45 are symmetrically installed along the central axis of the middle of the square connecting tube 44 .

[0046] The connecting teeth 46 are installed obliquely, and there are two triangular buckets 47 , which are symmetrically installed along the central axis of the middle of the square connecting tube 44 .

[0047] The arranged heat conductor 41 includes a U-shaped tube 411 and a heat conducting sheet 412. The opening of the U-shaped tube 411 is downward. The U-shaped tube 411 is fixedly connected to the inner wall of the transformer box 1 and close to the box door 3. The edge of the surface of the heat conducting sheet 412 is fixedly connected to the inner wall of the transformer box 1. The bottom end of the square connecting tube 44 is connected to the top of the U-shaped tube 411. A notch 413 is provided on the surface of the heat conducting sheet 412 and close to the inner wall of the transformer box 1. A heat conducting pipe 414 is connected to the middle of the surface of the U-shaped tube 411. The heat conducting pipe 414 passes through the center of the notch 413. The bottom of the outer circular surface of the heat pipe 414 is connected to a plug 415. When the transformer 2 generates heat during operation, as the temperature inside the transformer box 1 rises, through the principle of heat transfer, the heat inside the transformer box 1 can be transferred to the heat pipe 414 by utilizing the heat conduction of the heat conductive sheet 412. In addition, the heat pipe 414 is evenly installed on the surface of the U-shaped tube 411, and the heat conductive sheet 412 is evenly installed on the surface of the heat pipe 414. The heat pipe 414 and the heat conductive sheet 412 form an arranged heat dissipation mechanism, which can improve the heat transfer efficiency and promote the conduction of heat inside the transformer box 1.

[0048] The heat conducting sheets 412 are evenly distributed on the outer circumference of the heat conducting pipe 414 . The heat conducting sheets 412 are installed vertically, and the notches 413 are evenly opened on the surface of the heat conducting sheets 412 .

[0049] The U-shaped tube 411 is fixedly installed on the inner wall of the transformer box 1 and close to the box door 3, and the edge of the heat conducting plate 412 is fixed to the inner wall of the transformer box 1. The U-shaped tube 411 and the heat conducting plate 412 are fixed together to form an integrated structure, which can support the inner wall of the transformer box 1, thereby increasing the condition of the transformer box 1 itself and preventing deformation.

[0050] The heat conducting pipe 414 is evenly installed in the middle of the surface of the U-shaped tube 411 , and the heat conducting sheet 412 is fixedly connected to the heat conducting pipe 414 .

[0051] The staff turns on the suction fan 42 to work, using the suction force of the suction fan 42 and combining the connection between the right-angle air duct 43, the square connecting tube 44 and the U-shaped tube 411, so that the gas in the heat conduction pipe 414 enters the U-shaped tube 411 under the action of suction, and is transported by the right-angle air duct 43 and the square connecting tube 44, and is discharged through the air outlet of the suction fan 42, so that the gas in the heat conduction pipe 414 and the U-shaped tube 411 circulates. Through the flow of gas, the heat can be quickly taken out, and the heat in the transformer box 1 can be quickly dissipated.

[0052] The second embodiment, based on the first embodiment, see Figures 1 to 8 As shown:

[0053] The bottom of the inner cavity of the transformer box 1 and the position near the intubation 415 are provided with a supporting assembly 5, which includes a square base 51, the bottom of the square base 51 is fixedly connected to the bottom of the inner cavity of the transformer box 1, the top of the square base 51 is fixedly connected to a flat plate 52, a square mounting piece 53 is fixedly installed in the middle of the top of the flat plate 52, the surface of the transformer 2 and the position near the top are fixedly installed with the square mounting piece 53 by screws, the top of the flat plate 52 and the position near the intubation 415 are fixedly connected to a positioning cylinder 54, the top of the positioning cylinder 54 is fixedly connected to a sealing ring 5 5. The bottom end of the insert 415 passes through the center of the sealing ring 55 and extends to the inside of the positioning cylinder 54. An air hole 56 is provided inside the flat plate 52 near the square mounting member 53 and the positioning cylinder 54. The transformer 2 is mounted on the top of the square mounting member 53 and supported by the square base 51, so that the flat plate 52 separates the transformer 2 from the bottom of the inner cavity of the transformer box 1, and the bottom of the flat plate 52 is suspended from the bottom of the inner cavity of the transformer box 1 to form a suspended layer, which can play a moisture-proof role and make the transformer 2 less likely to get damp.

[0054] The positioning cylinders 54 are evenly distributed on the top of the flat plate 52 , and the positions of the positioning cylinders 54 correspond to the positions of the cannula 415 . The sealing ring 55 is made of rubber.

[0055] The bottom end of the insert tube 415 passes through the center of the sealing ring 55 and extends to the inside of the positioning cylinder 54. The sealing ring 55 can be sealed to prevent gas leakage. As the gas in the heat pipe 414 is discharged, the insert tube 415 draws air from the inside of the positioning cylinder 54, so that the gas in the air hole 56 is sucked out. The air inlet of the air hole 56 is opened below the transformer 2, and the air holes 56 are evenly opened inside the flat plate 52, so that the hot air around the transformer 2 can be sucked out, so that the heat dissipation is uniform.

[0056] The air inlet of the air hole 56 is opened at the bottom of the transformer 2 , the air outlet of the air hole 56 is opened inside the positioning cylinder 54 , and the air holes 56 are evenly opened inside the flat plate 52 .

[0057] The third embodiment, based on the first and second embodiments, see Figures 1 to 9 As shown:

[0058] The top of the transformer box 1 is equipped with an auxiliary mechanism 6, which includes a triangular ceiling 61. The bottom of the triangular ceiling 61 is fixedly connected to the top of the transformer box 1. A right-angle exhaust duct 62 is fixedly installed on the inner side of the triangular ceiling 61 and near the suction fan 42. The air inlet of the right-angle exhaust duct 62 is connected to the air outlet of the suction fan 42. The air outlet of the right-angle exhaust duct 62 passes through the inner wall of the triangular ceiling 61 and extends to the outside. The inside of the right-angle exhaust duct 62 and the position near the air outlet are fixed. A tension spring 63 is installed, and a blocking ball 64 is fixedly installed at the bottom end of the tension spring 63. A rubber ring 65 is fixedly connected to the surface of the blocking ball 64. As the gas is discharged from the air outlet of the suction fan 42, the gas enters the right-angle exhaust duct 62, and the gas can apply a blowing force to the blocking ball 64, so that the blocking ball 64 moves downward, and the blocking ball 64 applies a pulling force to the tension spring 63, and the tension spring 63 undergoes elastic deformation. The blocking ball 64 is used to move out of the air outlet of the right-angle exhaust duct 62, so that the exhaust is smooth.

[0059] The tension spring 63 is installed in the middle of the air outlet of the right-angle exhaust duct 62, and the surface of the rubber ring 65 fits with the inner wall of the air outlet of the right-angle exhaust duct 62. When the heat dissipation in the transformer box 1 is completed, the suction fan 42 stops working, so that the blocking ball 64 is blown away by the wind and the power disappears. Under the elastic tension of the tension spring 63, the blocking ball 64 drives the rubber ring 65 to move upward, and the surface of the rubber ring 65 fits with the inner wall of the air outlet of the right-angle exhaust duct 62, so that the air outlet of the right-angle exhaust duct 62 can be blocked, and external dust and impurities are not easily entered into the interior of the right-angle exhaust duct 62.

[0060] When in use, the staff opens the box door 3, and puts the transformer 2 into the interior of the transformer box 1 and installs it at the position of the square mounting piece 53. The transformer 2 is installed on the top of the square mounting piece 53 and supported by the square base 51, so that the flat plate 52 separates the transformer 2 from the bottom of the inner cavity of the transformer box 1, and the bottom of the flat plate 52 is suspended from the bottom of the inner cavity of the transformer box 1 to form a suspended layer, which can play a moisture-proof effect and prevent the transformer 2 from getting wet again.

[0061] When the transformer 2 generates heat during operation, as the temperature inside the transformer box 1 rises, the heat inside the transformer box 1 can be transferred to the heat pipe 414 through the heat transfer principle and the heat conduction of the heat conducting sheet 412. In addition, the heat conducting sheet 414 is evenly installed on the surface of the U-shaped tube 411, and the heat conducting sheet 412 is evenly installed on the surface of the heat conducting sheet 414. The heat conducting sheet 414 and the heat conducting sheet 412 form an arranged heat dissipation mechanism, which can improve the heat transfer efficiency and promote the conduction of heat inside the transformer box 1.

[0062] At this time, the staff turns on the suction fan 42 to work, and uses the suction force of the suction fan 42, combined with the connection between the right-angled air duct 43, the square connecting tube 44 and the U-shaped tube 411, so that the gas in the heat-conducting tube 414 is sucked into the U-shaped tube 411, and is transported by the right-angled air duct 43 and the square connecting tube 44, and is discharged through the air outlet of the suction fan 42, so that the gas in the heat-conducting tube 414 and the U-shaped tube 411 circulates. The flow of gas can quickly bring out the heat, and the heat in the transformer box 1 can be quickly dissipated;

[0063] At the same time, as the gas in the square connecting tube 44 flows, the airflow exerts a blowing force on the triangular bucket 47. Under the blowing of the airflow, the connecting teeth 46 and the triangular bucket 47 rotate together to adjust the angle, and the elastic membrane 45 can be pulled by the bottom end of the connecting teeth 46, causing the elastic membrane 45 to elastically deform. By making the elastic membrane 45 concave toward the inside of the square connecting tube 44, the cross-sectional area of ​​the inner cavity of the square connecting tube 44 can be reduced, thereby increasing the gas flow speed and further accelerating the heat dissipation.

[0064] The bottom end of the insert 415 passes through the center of the sealing ring 55 and extends to the interior of the positioning cylinder 54. The sealing ring 55 can be sealed to prevent gas leakage. As the gas in the heat pipe 414 is discharged, the insert 415 draws air from the interior of the positioning cylinder 54, so that the gas in the air hole 56 is sucked out. The air inlet of the air hole 56 is opened below the transformer 2. The air holes 56 are evenly opened inside the flat plate 52, so that the hot air around the transformer 2 can be sucked out, so that the heat dissipation is uniform.

[0065] Moreover, as the air outlet of the suction fan 42 discharges the gas, the gas enters the right-angle exhaust pipe 62, and the gas exerts a blowing force on the blocking ball 64, thereby causing the blocking ball 64 to move downward. The blocking ball 64 exerts a pulling force on the tension spring 63, and the tension spring 63 elastically deforms, and the blocking ball 64 is moved out of the air outlet of the right-angle exhaust pipe 62, so that the exhaust is smooth.

[0066] The U-shaped tube 411 is fixedly mounted on the inner wall of the transformer box 1 near the box door 3, and the edge of the heat conducting sheet 412 is fixed to the inner wall of the transformer box 1. The U-shaped tube 411 and the heat conducting sheet 412 are fixed together to form an integrated structure, which can support the inner wall of the transformer box 1, thereby increasing the strength of the transformer box 1 itself and preventing deformation.

[0067] When the heat dissipation in the transformer box 1 is completed, the suction fan 42 stops working, so that the wind force on the blocking ball 64 disappears, and under the elastic tension of the tension spring 63, the blocking ball 64 drives the rubber ring 65 to move upward, and the surface of the rubber ring 65 fits with the inner wall of the air outlet of the right-angle exhaust duct 62, so that the air outlet of the right-angle exhaust duct 62 can be blocked, and external dust and impurities are not easily entered into the interior of the right-angle exhaust duct 62.

[0068] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0069] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
