Description
Technical Field
[0001] The present invention relates to the technical field of dry-type transformers, and in particular to a dry-type transformer with a breathing heat dissipation structure. Background Art
[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. The cooling methods are divided into natural air cooling and forced air cooling. When the transformer is naturally cooled, it can operate continuously for a long time at the rated capacity. When forced air cooling, the transformer output capacity can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be allowed to operate continuously for a long time.
[0003] Dry-type transformers will generate high temperatures during long-term operation. In terms of heat dissipation, most of them open heat dissipation holes on the transformer shell, and the air flow is poor. At the same time, most transformers are outdoors. Affected by the environment, a large amount of dust will enter the shell and gather on the various components of the transformer. Excessive temperature and dust accumulation can easily cause aging of the components in the transformer and reduce its service life. At the same time, it is easy to cause circuit fires and safety accidents. Summary of the invention
[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A dry-type transformer with a breathing heat dissipation structure includes a base, the base is used to support the device, a transformer housing is fixedly installed on the top of the base, there are two bases, and the two bases are symmetrically arranged at the bottom of the transformer housing; A transformer body, wherein the transformer body is fixedly installed in the middle of the transformer housing, and a guide plate is arranged on the outside of the transformer body. There are several guide plates, and the guide plates are closely fitted to the outside of the transformer body. The cold air entering the transformer housing passes through the gaps between the multiple guide plates, and then the air carrying heat is discharged from the other end. By arranging the guide plates, the surface area of the outside of the transformer body is increased. At the same time, the guide plates can guide the flow of surrounding air to form a more orderly airflow and improve the heat dissipation effect. Several guide plates are evenly distributed on the outside of the transformer body; A heat dissipation component, wherein the heat dissipation component is arranged outside the transformer housing; Among them, the heat dissipation component includes a square plate, which is fixedly connected to the outer side of the transformer shell. There are multiple square plates, and the multiple square plates are evenly distributed on the outer side of the transformer shell. The external wind passes through the corrugated plate. By setting the heat dissipation plate as a corrugated plate, the contact area between the heat dissipation plate and the air is increased, so that in the heat exchange process, the heat can be more effectively transferred to the air, and the heat dissipation efficiency is higher. There are winds in multiple directions in the outside world, and the wind perpendicular to the corrugated plate passes through two adjacent corrugated plates. Since the two adjacent corrugated plates overlap to form a maze with a complex channel structure, the path length of the air flowing therein is increased, so that the opportunities for heat exchange transfer are increased, and the hot air stays therein for a longer time, which is similar to the heat dissipation efficiency of the heat dissipation plate. The corrugated plate can perform more sufficient heat exchange, thereby improving the heat dissipation effect and reducing the operating temperature of the equipment. A square groove is provided on the outer side of the square plate. There are two square grooves, which are symmetrically arranged on the outer side of the square plate. The inner wall of the square groove is slidably connected with a corrugated plate. The corrugated plate is elastic, and two adjacent corrugated plates are overlapped. The overlapping arrangement of the corrugated plates makes the flow of hot air in adjacent corrugated plates more uniform, thereby achieving more uniform heat dissipation, thereby avoiding local overheating and improving the stability and reliability of the entire system.

[0007] The present invention provides a dry-type transformer with a breathing heat dissipation structure. It has the following beneficial effects: 1. The dry-type transformer with a breathing heat dissipation structure forms a maze by overlapping two adjacent corrugated plates, and has a complex channel structure, which increases the path length of the air flowing therein, increases the opportunities for heat exchange and transfer, and allows the hot air to stay therein for a longer time, allowing for more sufficient heat exchange with the corrugated plates, thereby improving the heat dissipation effect and reducing the operating temperature of the equipment.
[0008] 2. The dry-type transformer with a breathing heat dissipation structure makes the hot air flow more evenly in adjacent corrugated plates through overlapping arrangement of corrugated plates, thereby achieving more uniform heat dissipation, thereby avoiding local overheating and improving the stability and reliability of the entire system. At the same time, the complex structure can have a certain damping effect on the air flow, reduce the turbulence and noise of the air flow, remove dust in the air, and reduce the dust from entering the interior of the transformer housing.
[0009] 3. The dry-type transformer with a breathing heat dissipation structure expands due to the heat of the thermosensitive component, so that the thermosensitive component drives the limit frame and the moving rod to move inward.

DETAILED DESCRIPTION
[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
[0015] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a dry-type transformer with a breathing heat dissipation structure, comprising a base 1, the base 1 is used to support the device, a transformer housing 2 is fixedly installed on the top of the base 1, there are two bases 1, and the two bases 1 are symmetrically arranged at the bottom of the transformer housing 2; Transformer body 3, the transformer body 3 is fixedly installed in the middle of the transformer housing 2, and a guide plate 4 is arranged on the outside of the transformer body 3, and the number of the guide plates 4 is several, and the guide plates 4 are closely fitted with the outside of the transformer body 3, and the cold air entering the transformer housing 2 passes through the gaps of the multiple guide plates 4, and then the air carrying heat is discharged from the other end. By setting the guide plates 4, the surface area of the outside of the transformer body 3 is increased, and the guide plates 4 can guide the flow of the surrounding air to form a more orderly airflow and improve the heat dissipation effect. Several guide plates 4 are evenly distributed on the outside of the transformer body 3; A heat dissipation component 5, which is arranged on the outside of the transformer housing 2; The heat dissipation component 5 includes a square plate 51, which is fixedly connected to the outer side of the transformer housing 2. There are multiple square plates 51, which are evenly distributed on the outer side of the transformer housing 2. The external wind passes through the corrugated plate 54. By setting the heat dissipation plate as the corrugated plate 54, the contact area between the heat dissipation plate and the air is increased, so that in the heat exchange process, the heat can be more effectively transferred to the air, and the heat dissipation efficiency is higher. There are winds from multiple directions in the outside world, and the wind perpendicular to the corrugated plate 54 passes through two adjacent corrugated plates 54. Since the two adjacent corrugated plates 54 overlap to form a maze with a complex channel structure, the path length of the air flowing therein is increased, so that the opportunities for heat exchange transfer are increased, and the hot air stays therein for a longer time, which is similar to the heat dissipation efficiency of the heat dissipation component 55. The corrugated plate 54 performs more sufficient heat exchange, thereby improving the heat dissipation effect and reducing the operating temperature of the equipment. A square groove 52 is opened on the outer side of the square plate 51. There are two square grooves 52. The two square grooves 52 are symmetrically arranged on the outer side of the square plate 51. The inner wall of the square groove 52 is slidably connected with a corrugated plate 54. The corrugated plate 54 is elastic, and two adjacent corrugated plates 54 are overlapped. Through the overlapping arrangement of the corrugated plates 54, the flow of hot air in adjacent corrugated plates 54 is more uniform, thereby achieving more uniform heat dissipation, thereby avoiding local overheating and improving the stability and reliability of the entire system. At the same time, the complex structure can have a certain damping effect on the air flow, reduce the turbulence and noise of the air flow, remove dust in the air, and reduce the dust from entering the interior of the transformer housing 2.
[0016] The second embodiment is based on the first embodiment. Figure 6 to Figure 7As shown, an extension plate 53 is fixedly connected to the middle of the outer side of the square plate 51, and a slide groove 57 is opened on the outer side of the square plate 51. The slide groove 57 is symmetrically arranged at the edge of the square plate 51 with the corrugated plate 54 as the center, and the slide groove 57 is symmetrically arranged on both sides of the square plate 51. The inside of the slide groove 57 is slidably connected with a slider 56. Under the elastic force of the corrugated plate 54, the two ends of the corrugated plate 54 contact the inner wall of the square groove 52. When the internal temperature of the transformer housing 2 increases, the thermal sensitive element 211 expands due to the heat, so that the thermal sensitive element 211 drives the limit frame 210 and the moving rod 25 to move inward. At this time, the moving rod 25 slides in the direction of the extension plate 53 inside the annular groove 55. The movable rod 25 drives the slider 56 to move. At this time, the corrugated plate 54 is compressed. At this time, the curvature of the corrugated plate 54 becomes larger. As the curvature of the corrugated plate 54 increases, its surface area is relatively larger. The corrugated plate 54 with a large curvature can change the flow path of the surrounding air to form an airflow that is more conducive to heat dissipation. When the air flows through the corrugated plate 54 with a large curvature, certain vortices and turbulence are generated, which enhances the heat exchange between the air and the surface of the heat sink and improves the heat dissipation effect of the transformer. The curvature of the corrugated plate 54 can be adjusted according to the temperature inside the transformer, thereby improving the heat dissipation efficiency of the transformer. The number of sliders 56 is the same as the number of waves of the corrugated plate 54, and the number of sliders 56 is the same as the number of waves of the corrugated plate 54. The two adjacent sliders 56 are symmetrically arranged alternately with the square plate 51 as the center. A connecting rod 58 is fixedly connected to one side of the slider 56 close to the corrugated plate 54. The connecting rod 58 passes through the corrugated plate 54. Both ends of the connecting rod 58 are fixedly connected to the two sliders 56 located on the same vertical line. The outer side of the connecting rod 58 close to the edge of the corrugated plate 54 is rotatably connected to a connecting plate 510. The end of the connecting plate 510 away from the connecting rod 58 is fixedly connected to a fixing rod 59. By arranging the fixing rod 59 and the connecting plate 510, the internal support of the corrugated plate 54 can be effectively dispersed, the pressure resistance of the corrugated plate can be improved, and the corrugated plate can be prevented from working for a long time. The corrugated plate may deform and twist due to its own weight, temperature changes or external factors. The internal support can limit the deformation of the corrugated plate to keep it flat and stable. At the same time, in a strong wind environment, the internal support can increase the rigidity of the corrugated plate to prevent the corrugated plate 54 from vibrating and deforming easily due to the action of wind, thereby improving its wind resistance. The outer side of the fixing rod 59 is rotatably connected to the outer side of the corrugated plate 54. There are two fixing rods 59, and the two fixing rods 59 are symmetrically arranged with the connecting rod 58 as the center. An annular groove 55 is opened on the outer side of the square plate 51 near the slide groove 57, and the annular groove 55 is located inside the slide groove 57, and the annular groove 55 runs through the square plate 51.
[0017] The third embodiment is based on the first and second embodiments. Figures 8 to 10As shown, the transformer housing 2 includes a shell 21, the bottom of the shell 21 is fixedly connected to the base 1, a through hole 22 is provided on the outside of the shell 21, the through hole 22 runs through the shell 21, a fixing plate 24 is fixedly installed inside the through hole 22, a groove 23 is provided on the fixing plate 24 near the outer edge of the through hole 22, the groove 23 and the protrusion inside the through hole 22 form a sealing frame, and the sealing frame can effectively prevent air leakage. During the operation of the transformer, the internal heat is heat-exchanged with the surrounding air through the heat dissipation component 5 inside the fixing plate 24. If the sealing frame exists Leakage, hot air will leak out, while cold air cannot fully enter, resulting in reduced heat dissipation efficiency. At the same time, the sealed frame can effectively prevent dust, debris and moisture from entering the inside of the transformer, avoiding these external substances from damaging the windings, core and insulating materials of the transformer, etc., affecting the performance and life of the transformer. A convex block is arranged inside the through hole 22 on the shell 21, and the shell 21 is snap-fitted with the groove 23 on the fixing plate 24 through the convex block. A notch 27 is arranged on the outer side of the fixing plate 24, and a buffer plate 28 is fixedly connected to the inner wall of the notch 27. The notch 27 and the groove 23 is vertically arranged, a limiting groove 29 is provided inside the fixing plate 24, a square plate 51 is located inside the limiting groove 29, a middle part of the square plate 51 is fixedly connected to the limiting groove 29, the limiting groove 29 is annularly arranged, an extension plate 53 is located inside the semicircular groove of the limiting groove 29, a water outlet groove 26 is provided on the outer side of the housing 21 near the through hole 22, and by providing the extension plate 53, airflow enters the transformer through the gap between the extension plate 53 and the limiting groove 29, and when the temperature difference between the inside and the outside is large, the cold air from the outside contacts the heat on the extension plate 53, water droplets are generated, and the water droplets are retained on the extension plate 53. The outer side of the long plate 53, then flows into the water outlet groove 26 along the extension plate 53 and is discharged to prevent water vapor in the air from entering the inside of the transformer. The water outlet groove 26 is located below the through hole 22, and the water outlet groove 26 is connected to the through hole 22. The outer side of the shell 21 is slidably connected with a moving rod 25. The moving rod 25 is U-shaped. The moving rod 25 is located inside the annular groove 55. The moving rod 25 passes through the shell 21. One end of the moving rod 25 is fixedly connected to a limit frame 210. The middle part of the limit frame 210 is fixedly connected with a thermosensitive component 211. The thermosensitive component 211 is fixedly connected to the inner wall of the shell 21.
[0018] When in use, the outside wind passes through the corrugated plate 54. By setting the heat sink as the corrugated plate 54, the contact area between the heat sink and the air is increased, so that in the heat exchange process, the heat can be more effectively transferred to the air, and the heat dissipation efficiency is higher. There are winds in multiple directions outside, and the wind perpendicular to the corrugated plate 54 passes through two adjacent corrugated plates 54. Since the two adjacent corrugated plates 54 overlap to form a maze with a complex channel structure, the path length of the air flowing therein is increased, so that the opportunities for heat exchange transfer are increased, and the hot air stays therein for a longer time, and a more sufficient heat exchange is carried out with the corrugated plate 54, thereby improving the heat dissipation effect and reducing the operating temperature of the equipment.
[0019] Under the elastic force of the corrugated plate 54, the two ends of the corrugated plate 54 are in contact with the inner wall of the square groove 52. When the internal temperature of the transformer housing 2 rises, the thermal sensitive component 211 expands due to the heat, so that the thermal sensitive component 211 drives the limit frame 210 and the moving rod 25 to move inward. At this time, the moving rod 25 slides in the direction of the extension plate 53 inside the annular groove 55, and the moving rod 25 drives the slider 56 to move. At this time, the corrugated plate 54 is compressed by force, and the curvature of the corrugated plate 54 becomes larger. As the curvature of the corrugated plate 54 increases, its surface area is relatively larger. The corrugated plate 54 with a large curvature can change the flow path of the surrounding air and form an airflow that is more conducive to heat dissipation.
[0020] The groove 23 and the protrusion inside the through hole 22 form a sealing frame, which can effectively prevent air leakage. During the operation of the transformer, the internal heat is exchanged with the surrounding air through the heat dissipation component 5 inside the fixing plate 24. If there is a leak in the sealing frame, the hot air will leak out, and the cold air cannot fully enter, resulting in reduced heat dissipation efficiency. At the same time, the sealing frame can effectively prevent dust, debris and moisture from entering the transformer.
