Description

Technical Field

[0001] This invention relates to the field of transformers, and more particularly to a heat-dissipating, rainproof, and switching type power transformer. Background Technology

[0002] A transformer is a complete set of power distribution equipment that can be used for terminal power supply and ring network power supply. It is very convenient to switch between them and ensures the reliability and flexibility of power supply. A transformer is a compact indoor and outdoor power distribution equipment that integrates traditional transformers in a box-type housing and is arranged in a certain wiring scheme. It organically combines functions such as high voltage power reception, transformer voltage reduction, and low voltage power distribution.

[0003] In our power system, various high and low voltage transformers are a very important and frequently used type of electrical equipment. At the same time, most transformers are usually installed outdoors to facilitate ventilation and maintenance.

[0004] However, outdoor transformers also have significant drawbacks, as they are easily exposed to wind and rain. This can lead to short circuits in the internal wiring and moisture buildup in the oil tank, affecting the transformer's lifespan. To address this, we have proposed a heat dissipation and rainproof switching transformer that can dissipate heat when it is not raining and also provide rain protection in rainy weather. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a heat-dissipating, rainproof, and switchable power transformer.

[0006] The heat dissipation and rainproof switching type power transformer provided in this application adopts the following technical solution: A heat dissipation and rainproof switching type power transformer includes a transformer body and a protective cover. The top surface of the protective cover has a heat dissipation opening, and a dustproof plate is provided at the heat dissipation opening. The dustproof plate includes an outer plate and an inner plate. The outer plate has a first vent hole, and the inner plate has a second vent hole. The inner plate slides inside the outer plate, and the outer plate has a sliding groove for the inner plate to slide. The top of the dustproof cover is provided with two rain shields, both of which are telescopic. Each rain shield includes a first plate and a second plate. The first plate has a first heat dissipation hole, and the second plate has a second heat dissipation hole. The end of the first plate away from the second plate is hinged to the top wall of the protective cover, and the ends of the second plates away from the first plate are hinged to each other. The top of the dustproof cover is provided with a lifting cylinder, and the piston rod of the lifting cylinder is connected to the hinge shaft of the two second plates. The lifting cylinder is located on both sides of the width direction of the dustproof plate. Both the dustproof plate and the rainproof plate have heat dissipation and rainproof functions. When the first plate is in its lowest position, the rain shield is attached to the dustproof plate, and at this time the first heat dissipation hole, the second heat dissipation hole, the first vent hole and the second vent hole are all connected. When the first plate rises to its highest position, the dustproof plate and the rainproof plate simultaneously enter the rainproof state. At this time, the first heat dissipation hole and the second heat dissipation hole are misaligned, and the first vent hole and the second vent hole are also misaligned. The inner plate moves simultaneously with the rain shield via a linkage assembly; A humidity sensor is installed on the outer wall of the protective cover. When the humidity sensor detects that the humidity value is greater than the set range, the piston rod of the lifting cylinder extends upward. When the humidity sensor detects that the humidity value is less than the set value, the piston rod of the lifting cylinder retracts.

[0007] Furthermore, the linkage assembly includes a first rack, a first spur gear, a first bevel gear, a second bevel gear, and a second spur gear. The first rack is vertically arranged and connected to the piston rod of the lifting cylinder via a first connecting rod. The first rack meshes with the first spur gear. The first bevel gear and the first spur gear are rotatably connected to the side wall of the outer plate via a first rotating shaft. The second bevel gear meshes with the first bevel gear. The second bevel gear and the second spur gear are rotatably connected to the outer plate via a second rotating shaft. The second spur gear meshes with the second rack, and the second rack is fixedly connected to the inner plate via a second connecting rod.

[0008] Furthermore, the inner wall of the slide groove is provided with a limiting groove for the sliding of the second rack.

[0009] Furthermore, a guide plate is provided on the outer wall of the outer plate, a guide block is fixedly connected to the side wall of the first rack, and a guide groove is provided on the first rack for the guide block to slide.

[0010] Furthermore, both the guide block and the guide groove are T-shaped.

[0011] Furthermore, the protective cover has an installation opening, and a protective plate is provided at the installation opening. The protective plate is fixed to the protective cover by bolts.

[0012] Furthermore, the length of the rain shield is greater than the width of the dustproof plate, and the lifting cylinder is located below the rain shield.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. When the humidity sensor detects that the humidity value is greater than the set range, the piston rod of the lifting cylinder extends upward, the first plate rises to the highest position, and the dustproof plate and the rainproof plate simultaneously enter the rainproof state. At this time, the first heat dissipation hole and the second heat dissipation hole are misaligned, so that the dustproof plate is sealed. At the same time, under the action of the linkage component, the first vent hole and the second vent hole are misaligned, and the rainproof plate is also sealed. Rainwater or humid air is difficult to enter the protective cover, thus playing a role in rain protection. When the humidity sensor detects that the humidity value is less than the set value, the piston rod of the lifting cylinder retracts, and the rain shield adheres to the dustproof plate. At this time, the first heat dissipation hole, the second heat dissipation hole, the first vent hole, and the second vent hole are all connected to achieve heat dissipation. Thus, the technical solution of this application can dissipate heat when it is not raining and can also provide rain protection in rainy weather. 2. By setting up the linkage components, the dustproof plate can be driven to move at the same time as the rainproof plate, thus saving energy.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a heat dissipation and rainproof switching type power transformer.

[0024] Reference Figure 1-5 The heat dissipation and rainproof switching type power transformer includes a transformer body 1 and a protective cover 2. The top surface of the protective cover 2 is provided with a heat dissipation opening, and a dustproof plate 3 is provided at the heat dissipation opening. The dustproof plate 3 includes an outer plate 31 and an inner plate 32. The outer plate 31 is provided with a first vent 311, and the inner plate 32 is provided with a second vent 321. The inner plate 32 slides inside the outer plate 31, and a sliding groove 312 is provided inside the outer plate 31 for the inner plate 32 to slide.

[0025] The top of the dustproof cover is equipped with two rain shields 4, both of which are telescopic. Each rain shield 4 includes a first plate 41 and a second plate 42. The first plate 41 has a first heat dissipation hole 411, and the second plate 42 has a second heat dissipation hole. The end of the first plate 41 away from the second plate 42 is hinged to the top wall of the protective cover 2, and the ends of the second plates 42 away from the first plate 41 are hinged to each other. The top of the dustproof cover is equipped with a lifting cylinder 5, and the piston rod of the lifting cylinder 5 is connected to the hinge shaft of the two second plates 42. The lifting cylinder 5 is located on both sides of the width direction of the dustproof plate 3 to improve the stability of the movement of the first plate 41.

[0026] A humidity sensor 6 is installed on the outer wall of the protective cover 2. When the humidity sensor 6 detects that the humidity value is greater than the set range, the piston rod of the lifting cylinder 5 extends upward. When the humidity sensor 6 detects that the humidity value is less than the set value, the piston rod of the lifting cylinder 5 retracts.

[0027] The length of the rain shield 4 is greater than the width of the dust shield 3, and the lifting cylinder 5 is located below the rain shield 4, reducing the possibility of damage to the lifting cylinder 5.

[0028] The protective cover 2 has an installation port 21, through which the transformer body 1 can be installed into the protective cover 2. A protective plate 22 is provided at the installation port 21, and the protective plate 22 is fixed to the protective cover 2 by bolts.

[0029] Both the dustproof plate 3 and the rainproof plate 4 have heat dissipation and rainproof functions.

[0030] When the first plate 41 is in the lowest position, the rain shield 4 is attached to the dustproof plate 3, and at this time the first heat dissipation hole 411, the second heat dissipation hole, the first vent 311 and the second vent 321 are all connected. When the first plate 41 rises to its highest position, the dustproof plate 3 and the rainproof plate 4 simultaneously enter the rainproof state. At this time, the first heat dissipation hole 411 and the second heat dissipation hole are misaligned, and the first vent hole 311 and the second vent hole 321 are also misaligned.

[0031] The inner plate 32 moves simultaneously with the rain shield 4 via the linkage assembly 7. The linkage assembly 7 is located at one of the lifting cylinders 5. The linkage assembly 7 includes a first rack 71, a first spur gear 72, a first bevel gear 73, a second bevel gear 74, and a second spur gear 75. The first rack 71 is vertically arranged and connected to the piston rod of the lifting cylinder 5 via a first connecting rod. The first rack 71 meshes with the first spur gear 72. The first bevel gear 73 and the first spur gear 72 are rotatably connected to the side wall of the outer plate 31 via a first rotating shaft. The second bevel gear 74 meshes with the first bevel gear 73. The second bevel gear 74 and the second spur gear 75 are rotatably connected to the outer plate 31 via a second rotating shaft. The second spur gear 75 meshes with the second rack 76, and the second rack 76 is fixedly connected to the inner plate 32 via a second connecting rod. By setting up the linkage assembly 7, the dust shield 3 can be driven to move simultaneously with the rain shield 4, saving energy.

[0032] When the piston rod of the lifting cylinder 5 extends to the point where the first heat dissipation hole 411 and the second heat dissipation hole are misaligned, the first rack 71 rises, the first spur gear 72 rotates, the first bevel gear 73 rotates, the second bevel gear 74 rotates, the second spur gear 75 rotates, and the second rack 76 slides, causing the first vent hole 311 and the second vent hole 321 to be misaligned.

[0033] A guide plate 8 is provided on the outer wall of the outer plate 31. A guide block 711 is fixedly connected to the side wall of the first rack 71. A guide groove 81 is provided on the first rack 71 for the guide block 711 to slide. The guide block 711 slides in the guide groove 81. Both the guide block 711 and the guide groove 81 are T-shaped, which limits and guides the sliding of the first rack 71. A limiting groove 313 is provided on the inner wall of the slide groove 312 for the sliding of the second rack 76, which limits and guides the sliding of the second rack 76.

[0034] The implementation principle of a heat dissipation and rainproof switching type power transformer in this application embodiment is as follows: When the humidity sensor 6 detects that the humidity value is greater than the set range, the piston rod of the lifting cylinder 5 extends upward, the first plate 41 rises to the highest position, and the dustproof plate 3 and the rainproof plate 4 simultaneously enter the rainproof state. At this time, the first heat dissipation hole 411 and the second heat dissipation hole are misaligned, so that the dustproof plate 3 is sealed. At the same time, under the action of the linkage component 7, the first vent 311 and the second vent 321 are misaligned, and the rainproof plate 4 is also sealed. Rainwater or humid air is difficult to enter the protective cover 2, thus playing a role in rain protection. When the humidity sensor 6 detects that the humidity value is less than the set value, the piston rod of the lifting cylinder 5 retracts, and the rain shield 4 is attached to the dustproof plate 3. At this time, the first heat dissipation hole 411, the second heat dissipation hole, the first vent hole 311 and the second vent hole 321 are all connected to achieve heat dissipation. Thus, the technical solution of this application can dissipate heat when it is not raining and can also provide rain protection on rainy days.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
