Description

Technical Field

[0001] The present invention relates to the technical field of substations, and specifically relates to a box-type substation with an arranged low-voltage heat dissipation structure. Background Art

[0002] A box-type substation, also called a prefabricated substation or a prefabricated transformer substation, is a compact complete power distribution device that combines high-voltage switchgear, distribution transformers, low-voltage power distribution devices, and reactive power compensation devices, etc. according to a certain wiring scheme in one or several boxes. It mainly includes high-voltage switch cabinets, ring main units, load switches, fuses, disconnectors, earthing switches and other equipment, which play the roles of switching on and off, controlling and protecting in the power distribution system. Inside, there are distribution transformers, busbars and enclosed connection lines, etc. The distribution transformer converts high-voltage current into low-voltage current, and the busbar is used to connect each electrical equipment to realize the transmission of electric energy. It is usually composed of low-voltage switch cabinets, low-voltage feeder circuit breakers, etc., and is responsible for distributing the low-voltage current to different electrical equipment or power distribution networks.

[0003] In the prior art, long strip-shaped upright supports are mostly used to support the air ducts on the coil insulation layer. After the installation of the long strip-shaped upright supports, the pads may block the air ducts formed by the supports, thereby interfering with the heat dissipation work. Summary of the Invention

[0004] To achieve the above purposes, the present invention is realized through the following technical solutions: A box-type substation with an arranged low-voltage heat dissipation structure, comprising:

[0005] A main body, the back of the main body is fixedly connected with an exhaust component;

[0006] A transformer component, the transformer component is installed inside the main body;

[0007] The transformer component includes a bracket, the top of the bracket is fixedly connected with a pad, the top of the pad is fixedly connected with a coil mechanism, and an iron core is installed on the top of the coil mechanism;

[0008] The coil mechanism includes an insulating layer, ventilation grooves are opened inside the insulating layer, support bars are evenly arranged inside the ventilation grooves, the side surface of the support bars is fixedly connected with the inside of the ventilation grooves, and the shape of the support bars is point-breaking type. Air duct rods are evenly arranged inside the ventilation grooves, the side surface of the air duct rods is fixedly connected with the inside of the ventilation grooves, the support bars and the air duct rods are sequentially arranged in a surrounding manner inside the ventilation grooves, metal connecting pieces are arranged on the side surface of the insulating layer, the number of the metal connecting pieces is two, and the two metal connecting pieces are respectively fixedly connected with both sides of the insulating layer;

[0009] By electrically connecting two conductor sheets at the bottom of the insulating layer to the busbar electrical equipment of the external device, the extraction and distribution of electric energy are realized. At the same time, a radiator can be installed on the bracket. By increasing the heat dissipation area and accelerating the air flow, the heat generated during the operation of the transformer can be dissipated into the surrounding environment;

[0010] In the low-voltage coil, the copper foil is usually wound around the iron core. As the conductive part of the coil, the copper foil is tightly wound layer by layer on the insulating layer. It is spread open by spacers and together with the spacers surrounds the low-voltage coil for a full circle. Multiple such structures are combined together to form the winding of the low-voltage coil;

[0011] Since the interlayer insulation is soft and the spacers stick to the interlayer insulation, the interlayer insulation can carry the spacers and surround the low-voltage coil for a full circle for one coil. Using four such combinations of interlayer insulation and spacers ensures that the spacers can spread open the copper foil, and there is an air duct left between the copper foils to ensure heat dissipation;

[0012] Relative to using long strip vertical spacers, after installation, the pads may block the air ducts formed between the spacers. While using point-break spacers, even if the pads block the air duct openings at the upper and lower ends, due to being point-break, the wind can blow into the interior of the air duct holes originally blocked by the pads from the air duct rods or the gaps misaligned with the air duct rods, forming better ventilation and heat dissipation;

[0013] The exhaust component includes an exhaust housing. The side of the exhaust housing is fixedly connected to the back of the main body. A fixing frame is fixedly connected to the inner side of the exhaust housing close to the main body. A motor is fixedly connected to the side of the fixing frame. The output end of the motor is fixedly connected to one side of the fan blade close to the fixing frame. A fan blade is rotatably connected to the side of the fixing frame away from the motor. A net plate is fixedly connected to the inner side of the exhaust housing close to the fan blade. Both sides of the exhaust housing are provided with notches. Collection mechanisms are fixedly connected to both sides of the notches. The sides of the collection mechanisms are in contact with the notches. A rotating mechanism is rotatably connected to the side of the net plate away from the fan blade. A baffle is fixedly connected to the side of the exhaust housing away from the motor;

[0014] When the transformer component works in the main body, by turning on the motor, the output end of the motor drives the fan blade to rotate on the fixing frame. Thus, when the dry-type transformer is working, the temperature inside the main body can be cooled and ventilated. When the fan blade rotates, it simultaneously drives the rotating mechanism to rotate on the net plate, thus avoiding a large amount of dust accumulating on the net plate during long-term heat exchange inside the main body;

[0015] At the same time, when the rotating mechanism rotates on the net plate, by turning on the collection mechanism, the dust cleaned and dropped by the rotating mechanism on the net plate can enter the collection mechanism through the suction force of the collection mechanism through the notch for storage and collection work;

[0016] Preferably, the rotating mechanism includes a rotating shaft. The side surface of the rotating shaft is rotatably connected to the inner side of the mesh plate. One end of the rotating shaft away from the baffle is fixedly connected to one side of the fan blade away from the motor output end. The other end of the rotating shaft is rotatably connected to the side surface of the baffle. Both sides of the rotating shaft are fixedly connected with rotating frames. The side surface of the rotating frame is fixedly connected with cleaning brushes. The side of the cleaning brush away from the rotating frame is in contact with the side of the mesh plate close to the rotating frame. A rotating groove is formed in the middle of the side surface of the rotating frame. An arc-shaped frame is rotatably connected to the inner side of the rotating groove. Arc-shaped grooves are evenly formed in the side surface of the arc-shaped frame.

[0017] When the output end of the motor drives the fan blade to rotate on the fixed frame, the rotating shaft is driven to rotate by the fan blade at the same time, so that the rotating shaft drives the rotating frames on both sides to rotate, and further the rotating frames drive the cleaning brushes to clean the side surface of the mesh plate, thus avoiding that a large amount of dust in the outside world will accumulate on the mesh plate during long-term ventilation work, which will interfere with the ventilation effect of the mesh plate.

[0018] At the same time, when the rotating shaft drives the cleaning brush to clean the side surface of the mesh plate through the rotating frame, when the rotating frame rotates, the arc-shaped frame is driven to rotate in the rotating groove by the action of centrifugal force. By evenly arranging arc-shaped grooves on the side surface of the arc-shaped frame, when the arc-shaped frame rotates in the rotating groove, it can grab the flocculent or strip-shaped dust falling during the cleaning work of the mesh plate through the arc-shaped grooves, thus avoiding the phenomenon that the dust falling on the mesh plate will accumulate on the cleaning brush in large quantities during the cleaning work of the cleaning brush, which will interfere with the cleaning work.

[0019] Preferably, the collecting mechanism includes two collecting outer shells. The two collecting outer shells are symmetrically arranged on the side surface of the heat dissipation outer shell. The side surface of the collecting outer shell is fixedly connected to the side surface of the exhaust outer shell. The side of the collecting outer shell close to the exhaust outer shell abuts against the notch. An air suction component is fixedly connected to the side of the collecting outer shell away from the exhaust outer shell. A filter screen is fixedly connected to the inner side of the collecting outer shell. Grabbing components are evenly arranged on the inner side of the collecting outer shell. Both ends of the grabbing component are rotatably connected to the inner side of the collecting outer shell.

[0020] When the rotating frame drives the cleaning brush to clean the mesh plate, by turning on the air suction component, due to the suction force generated by the air suction component, the dust falling from the cleaning of the mesh plate by the cleaning brush can enter the collecting outer shell through the notch for collection work. At the same time, by arranging grabbing components in the inner cavity of the collecting outer shell, when the air suction component performs suction work, the grabbing components rotate in the inner cavity of the collecting outer shell due to the suction force generated by the air suction component. The rotating grabbing components can stir the dust in the collecting outer shell to prevent the dust from accumulating in blocks or forming blockages in the collecting outer shell.

[0021] Preferably, the grasping assembly includes a circular shaft, both ends of the circular shaft are fixedly connected with circular plates, one side of the circular plate away from the circular shaft is rotatably connected to the inner side of the collection housing, the side surface of the circular shaft is evenly provided with bent rods, the number of the bent rods is five, the five bent rods are arranged centered on the circular shaft, and the side surface of the bent rod is fixedly connected to the inner side of the circular shaft. The side of the circular shaft away from the bent rod is evenly provided with grasping rods, the number of the grasping rods is five, the five grasping rods are evenly arranged centered on the circular shaft, and the side surface of the grasping rod is fixedly connected to the inner side of the circular shaft. A rotating shaft is rotatably connected to the inner side of the grasping rod, both sides of the rotating shaft are fixedly connected with arc-shaped rods, and a grasping groove is opened on one side of the arc-shaped rod away from the rotating shaft;

[0022] When the air suction assembly performs the air suction and collection work on the dust swept and dropped on the mesh plate, the bent rods and the grasping rods drive the circular shaft to rotate in the inner cavity of the collection housing, so that the grasping rods and the bent rods grab and disperse the flocculent dust entering the inner cavity of the collection housing;

[0023] At the same time, by arranging an arc-shaped rod and a rotating shaft on the inner side of the grasping rod, when the circular shaft rotates in the inner cavity of the collection housing, the rotating shaft can drive the arc-shaped rod to rotate in the inner side of the grasping rod. At the same time, by opening a grasping groove on the side surface of the arc-shaped rod; the grasping groove increases the contact points and contact area between the arc-shaped rod and the dust, and can more effectively grab the flocculent dust entering the inner cavity of the collection housing.

[0024] The present invention provides a box-type substation with an arranged low-voltage heat dissipation structure. It has the following beneficial effects:

[0025] 1. For the box-type substation with the arranged low-voltage heat dissipation structure, it is provided with discontinuous struts. The interlayer insulating tape is used to surround the low-voltage coil with the discontinuous struts, which can ensure that the struts open the copper foil and leave an air duct, and the wind can blow into the air duct holes blocked by the spacer blocks from the gaps where the air duct rods are misaligned, forming a better ventilation and heat dissipation path, effectively improving the heat dissipation efficiency, reducing the coil temperature, avoiding problems such as insulation aging and equipment performance degradation caused by overheating, and extending the service life of the equipment.

[0026] 2. For the box-type substation with the arranged low-voltage heat dissipation structure, the discontinuous struts are provided. Compared with the long strip vertical struts, it can better adapt to the space layout during installation, reduce the space waste caused by the shape of the struts, make the internal structure of the equipment more compact, be conducive to reducing the volume of the equipment, and improving the integration degree and space utilization efficiency of the equipment.

[0027] 3. The box-type substation with an arranged low-voltage heat dissipation structure is provided with a rotating mechanism. If a large amount of dust accumulates on the cleaning brush, it may aggravate the wear of the cleaning brush. The wear situation is reduced by grasping dust through the arc-shaped groove, thereby prolonging the service life of the cleaning brush, reducing the maintenance cost and replacement frequency of the equipment.

[0028] 4. The box-type substation with an arranged low-voltage heat dissipation structure is provided with a grasping component. For some larger particulate dust or flocculent dust, the rotation of the grasping component can disperse them, making it easier for them to be carried by the air flow or adsorbed on the inner wall of the collection housing, keeping the internal passage of the collection housing unobstructed, ensuring that the suction force of the suction component can act effectively, and maintaining a good dust suction effect.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a box-type substation with an arranged low-voltage heat dissipation structure, including:

[0043] Main body 1, and an exhaust component 2 is fixedly connected to the back of the main body 1;

[0044] Transformer component 3, and the transformer component 3 is installed inside the main body 1;

[0045] The transformer component 3 includes a bracket 31, a pad 32 is fixedly connected to the top of the bracket 31, a coil mechanism 33 is fixedly connected to the top of the pad 32, and an iron core 34 is installed on the top of the coil mechanism 33;

[0046] Please refer to Figures 1 - 5The coil mechanism 33 includes an insulating layer 331, a ventilation slot 332 is provided on the inner side of the insulating layer 331, and struts 333 are evenly arranged on the inner side of the ventilation slot 332. The side of the struts 333 is fixedly connected to the inner side of the ventilation slot 332, and the shape of the struts 333 is dot-interrupted. Airway rods 334 are evenly arranged on the inner side of the ventilation slot 332, and the side of the airway rods 334 is fixedly connected to the inner side of the ventilation slot 332. The struts 333 and the airway rods 334 are sequentially arranged around the inner side of the ventilation slot 332. A metal connecting sheet 335 is provided on the side of the insulating layer 331. The number of the metal connecting sheets 335 is two, and the two metal connecting sheets 335 are respectively fixedly connected to the two sides of the insulating layer 331;

[0047] By connecting the two conductor sheets at the bottom of the insulating layer 331 to the busbar electrical equipment of the external equipment, the extraction and distribution of electric energy can be realized. At the same time, by installing a heat sink on the bracket 31, the heat generated during the operation of the transformer can be dissipated to the surrounding environment by increasing the heat dissipation area and accelerating the air flow;

[0048] In the low-voltage coil, the copper foil is usually wound around the iron core 34. As the conductive part of the coil, the copper foil is tightly wound on the insulating layer 331 layer by layer, and is stretched open by the support bar 333. Together with the support bar 333, it surrounds the low-voltage coil for a full circle. Multiple such structures are combined together to form the winding of the low-voltage coil.

[0049] Since the interlayer insulation is soft, the support bar 333 is adhered to the interlayer insulation, so that the interlayer insulation with the support bar 333 can surround the low-voltage coil for a whole circle. The combination of four such interlayer insulations and the support bar 333 ensures that the support bar 333 can support the copper foil and ensure that there is an airway with the copper foil to ensure heat dissipation;

[0050] Compared with the use of long upright support bars 333, after installation, the pads may block the airway formed between the support bars 333 and the support bars 333. However, with the use of the point-interrupted support bars 333, even if the pads 32 block the airway openings at the upper and lower ends, because of the point-interrupted type, the wind can blow from the airway rod or the gap misaligned with the airway rod to the inside of the airway hole originally blocked by the pads, thereby forming better ventilation and heat dissipation.

[0051] See also Figures 1 - 8 , the present invention provides a technical solution:

[0052] The exhaust component 2 includes an exhaust housing 21. The side of the exhaust housing 21 is fixedly connected to the back of the main body 1. A fixing frame 22 is fixedly connected to the inner side of the exhaust housing 21 close to the main body 1. A motor 23 is fixedly connected to the side of the fixing frame 22. The output end of the motor 23 is fixedly connected to one side of the fan blade 24 close to the fixing frame 22. The fan blade 24 is rotatably connected to the side of the fixing frame 22 away from the motor 23. A net plate 26 is fixedly connected to the inner side of the exhaust housing 21 close to the fan blade 24. Grooves 29 are formed on both sides of the exhaust housing 21. Collection mechanisms 25 are fixedly connected to both sides of the groove 29. The side of the collection mechanism 25 abuts against the groove 29. A rotating mechanism 28 is rotatably connected to the side of the net plate 26 away from the fan blade 24. A baffle 27 is fixedly connected to the side of the exhaust housing 21 away from the motor 23;

[0053] When the transformer component 3 works in the main body 1, by starting the motor 23, the output end of the motor 23 drives the fan blade 24 to rotate on the fixing frame 22, so that when the dry-type transformer works, the temperature inside the main body 1 can be cooled and ventilated. When the fan blade 24 rotates, it simultaneously drives the rotating mechanism 28 to rotate on the net plate 26, thus preventing a large amount of dust from accumulating on the net plate 26 when heat exchange is carried out inside the main body 1 for a long time;

[0054] At the same time, when the rotating mechanism 28 rotates on the net plate 26, by starting the collection mechanism 25, the dust cleaned and dropped by the rotating mechanism 28 on the net plate 26 can enter the collection mechanism 25 through the suction force of the collection mechanism 25 through the groove 29 for storage and collection work;

[0055] Please refer to Figures 1 - 9 , the rotating mechanism 28 includes a rotating shaft 281. The side of the rotating shaft 281 is rotatably connected to the inner side of the net plate 26. One end of the rotating shaft 281 away from the baffle 27 is fixedly connected to one side of the fan blade 24 away from the output end of the motor 23. The other end of the rotating shaft 281 is rotatably connected to the side of the baffle 27. Rotating frames 282 are fixedly connected to both sides of the rotating shaft 281. A cleaning brush 283 is fixedly connected to the side of the rotating frame 282. The side of the cleaning brush 283 away from the rotating frame 282 is in contact with the side of the net plate 26 close to the rotating frame 282. A rotating groove 284 is formed in the middle of the side of the rotating frame 282. An arc-shaped frame 285 is rotatably connected to the inner side of the rotating groove 284. Arc-shaped grooves 286 are evenly formed on the side of the arc-shaped frame 285;

[0056] When the output end of the motor 23 drives the fan blade 24 to rotate on the fixed frame 22, the fan blade 24 drives the rotating shaft 281 to rotate at the same time, so that the rotating shaft 281 drives the rotating frames 282 on both sides to rotate, and then the rotating frames 282 drive the cleaning brushes 283 to clean the side surface of the net plate 26, thus avoiding a large amount of dust in the outside world from gathering on the net plate 26 during long-term ventilation work, which may interfere with the ventilation effect of the net plate 26;

[0057] At the same time, when the rotating shaft 281 drives the cleaning brush 283 to clean the side surface of the net plate 26 through the rotating frame 282, when the rotating frame 282 rotates, due to the action of centrifugal force, the arc-shaped frame 285 is driven to rotate in the rotating groove 284. By evenly arranging arc-shaped grooves 286 on the side surface of the arc-shaped frame 285, when the arc-shaped frame 285 rotates in the rotating groove 284, it can grab the flocculent or strip-shaped dust that falls during the cleaning work of the net plate 26 through the arc-shaped grooves 286, thus avoiding the phenomenon that a large amount of dust falling on the net plate 26 will gather on the cleaning brush 283 during the cleaning work of the cleaning brush 283, which may interfere with the cleaning work;

[0058] By the arc-shaped frame 285 rotating in the rotating groove 284 and using the arc-shaped groove 286 to grab flocculent or strip-shaped dust, it can effectively reduce the problem of dust falling and accumulating during the cleaning process, avoid a large amount of dust gathering on the cleaning brush 283 and interfering with the cleaning work, so that the cleaning brush 283 can clean the side surface of the net plate 26 more efficiently and improve the cleaning cleanliness of the net plate 26;

[0059] Please refer to Figures 1 - 10 As shown in the figure, the collection mechanism 25 includes two collection outer shells 251, which are symmetrically arranged on the side surface of the heat dissipation outer shell. The side surface of the collection outer shell 251 is fixedly connected to the side surface of the exhaust outer shell 21. One side of the collection outer shell 251 close to the exhaust outer shell 21 abuts against the notch 29. The side of the collection outer shell 251 away from the exhaust outer shell 21 is fixedly connected with a suction component 252. A filter screen 253 is fixedly connected to the inner side of the collection outer shell 251. Grabbing components 254 are evenly arranged on the inner side of the collection outer shell 251, and both ends of the grabbing component 254 are rotatably connected to the inner side of the collection outer shell 251;

[0060] When the rotary rack 282 drives the cleaning brush 283 to clean the mesh plate 26, by turning on the suction component 252, the suction force generated by the suction component 252 enables the dust swept off the mesh plate 26 by the cleaning brush 283 to enter the collection housing 251 through the notch 29 for collection. At the same time, a grasping component 254 is arranged in the inner cavity of the collection housing 251. When the suction component 252 performs suction work, the suction force generated by the suction component 252 causes the grasping component 254 to rotate in the inner cavity of the collection housing 251. The rotating grasping component 254 can stir the dust in the collection housing 251 to prevent the dust from accumulating in blocks or forming blockages in the collection housing 251;

[0061] Please refer to Figures 1 - 11 , the grasping component 254 includes a circular shaft 2542. Circular plates 2541 are fixedly connected to both ends of the circular shaft 2542. The side of the circular plate 2541 away from the circular shaft 2542 is rotatably connected to the inner side of the collection housing 251. Bent rods 2543 are evenly arranged on the side surface of the circular shaft 2542. The number of bent rods 2543 is five. The five bent rods 2543 are arranged centered on the circular shaft 2542, and the side surface of the bent rod 2543 is fixedly connected to the inner side of the circular shaft 2542. Grasping rods 2544 are evenly arranged on the side of the circular shaft 2542 away from the bent rods 2543. The number of grasping rods 2544 is five. The five grasping rods 2544 are evenly arranged centered on the circular shaft 2542, and the side surface of the grasping rod 2544 is fixedly connected to the inner side of the circular shaft 2542. A rotating shaft 2545 is rotatably connected to the inner side of the grasping rod 2544. Arc-shaped rods 2546 are fixedly connected to both sides of the rotating shaft 2545. A grasping groove 2547 is formed on the side of the arc-shaped rod 2546 away from the rotating shaft 2545;

[0062] When the suction component 252 sucks and collects the dust swept off the mesh plate 26, the bent rods 2543 and the grasping rods 2544 drive the circular shaft 2542 to rotate in the inner cavity of the collection housing 251, so that the grasping rods 2544 and the bent rods 2543 grab and disperse the flocculent dust entering the inner cavity of the collection housing 251;

[0063] At the same time, by arranging the arc-shaped rod 2546 and the rotating shaft 2545 on the inner side of the grasping rod 2544, when the circular shaft 2542 rotates in the inner cavity of the collection housing 251, the rotating shaft 2545 can drive the arc-shaped rod 2546 to rotate inside the grasping rod 2544. At the same time, a grasping groove 2547 is formed on the side surface of the arc-shaped rod 2546; the grasping groove 2547 increases the contact points and contact area between the arc-shaped rod 2546 and the dust, and can more effectively grab the flocculent dust entering the inner cavity of the collection housing 251;

[0064] During the rotation process, the grasping rod 2544 and the bent rod 2543 perform the work of scattering flocculent dust, which can disperse the flocculent dust agglomerates, prevent them from accumulating into blocks and clogging the collection housing 251 or affecting subsequent dust collection and treatment, and contribute to maintaining the smooth operation of the collection system.

All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
