Description

Technical Field

[0001] This invention relates to the technical field of distribution transformers, specifically to an air-cooled energy-saving distribution transformer. Background Technology

[0002] Three-phase oil-immersed transformers use a fully oil-filled, sealed corrugated tank shell. The tank is permanently sealed and adapts to the expansion of the oil through its own elasticity. Oil-immersed transformers have been widely used in various power distribution equipment.

[0003] Currently, the market uses traditional energy-saving distribution transformers, which have insufficient heat dissipation, are prone to dust accumulation inside, and have high internal temperatures, posing safety risks. In addition, the noise generated by the distribution transformers during operation affects the lives of surrounding residents. Summary of the Invention

[0004] This invention provides an air-cooled, energy-saving distribution transformer to solve the technical problems mentioned in the background section.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A wind-cooled energy-saving distribution transformer includes a transformer housing and a wind-cooling device and a heat dissipation device disposed on one side of the transformer housing. The transformer housing is equipped with a noise reduction mechanism. A first window is opened through the outer wall of one side of the transformer housing, and a second window is opened through the outer wall of the other side of the transformer housing. An oil tank is connected through the bottom of the transformer housing, and a support base plate is connected to the bottom of the oil tank. A fixing mechanism is provided at the bottom of the support base plate.

[0007] The air-cooling device includes a cooling fan, a cooling block, a cooling plate, and a first cooling fan. The cooling block is located between and connected to the cooling fan and the cooling plate. The first cooling fan is connected to the side of the cooling plate away from the cooling block.

The cooling fan is located at the first window, and the first cooling fan is located at the air outlet window of the dustproof box.

[0008] The heat dissipation device includes a heat dissipation window, which is arranged in a cuboid structure. A second heat dissipation fan is symmetrically arranged on the outside of the heat dissipation window. One end of the outer wall of the heat dissipation window is connected to the inner wall of the second window. A first limiting frame is arranged on the inner wall of the heat dissipation window. A first limiting rod is connected to the middle of the first limiting frame. A dustproof mechanism is arranged on the outer wall of the heat dissipation window.

[0009] The noise reduction mechanism includes a first honeycomb sound insulation board, a sound insulation felt, a sound insulation cotton, and a second honeycomb sound insulation board, which are sequentially pasted and connected together.

[0010] Preferably, the fixing mechanism includes a fixing frame with a plurality of first bolt fixing holes evenly distributed throughout it. The fixing frame is symmetrically arranged at the bottom of the support base plate. Fixing grooves are provided through the top of both sides of the support base plate, and fixing screws are inserted through the fixing grooves. The fixing screws pass through the first bolt fixing holes and connect to the fixing frame. The fixing mechanism facilitates the connection between the transformer box and the external support, and the fixing grooves facilitate the adjustment of the position of the fixing frame for easy installation.

[0011] Preferably, the dustproof mechanism includes a dustproof frame, one end of which is connected to the inner wall of the heat dissipation window via a pivot. A second limiting frame is connected to the outer wall of the dustproof frame near the heat dissipation window. Second limiting rods are connected to both ends and the middle of the inner wall of the second limiting frame. A dustproof net is pasted inside the second limiting frame. While the second cooling fan dissipates the heat inside the transformer tank, it also adsorbs dust inside the transformer tank through the dustproof net, protecting the parts inside the transformer tank and preventing dust accumulation.

[0012] Preferably, the second cooling fan is connected to the inner wall of the dustproof frame on the side away from the second limiting frame. The second cooling fan is fixed to the dustproof frame. While the second cooling fan dissipates the heat inside the transformer box, the dustproof frame is easy to open for cleaning.

[0013] Preferably, when the dustproof frame is closed, it is located inside the heat dissipation window, and its outer walls are connected to the inner walls of the heat dissipation window. The dustproof net absorbs and filters dust, and opening the dustproof frame facilitates the replacement and cleaning of the dustproof net.

[0014] Preferably, the outer wall of the first honeycomb sound insulation panel away from the sound insulation felt is connected to the inner wall of the transformer box. The noise reduction mechanism achieves the purpose of absorbing the noise generated by the main body of the energy-saving distribution transformer, reducing the noise and thus reducing the impact on the daily life of the surrounding residents.

[0015] Preferably, the dustproof frame is provided with an opening and closing handle on the outer wall of the end away from the rotating shaft. The opening and closing handle makes it easy to open the dustproof frame and replace and clean the dustproof net pasted inside the second limiting frame, which is convenient to use.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] Firstly, this invention achieves the purpose of reducing the air temperature inside the transformer tank by setting up an air-cooling device, thereby enhancing the heat dissipation effect on the main body of the energy-saving distribution transformer.

[0018] Secondly, the high temperature inside the transformer tank is dissipated in a timely manner through the heat dissipation device. At the same time, the heat dissipation device absorbs dust inside the transformer tank through the dustproof net, protecting the parts inside the transformer tank and preventing dust accumulation.

[0019] Thirdly, by setting up a noise reduction mechanism, the noise generated by the main body of the energy-saving distribution transformer is absorbed, thereby reducing the noise and minimizing the impact on the daily lives of surrounding residents.

[0031] Please refer to the appendix carefully. Figure 1-6As shown, in a preferred embodiment of the present invention, an air-cooled energy-saving distribution transformer includes a transformer housing 1 and an air-cooling device 2 and a heat dissipation device 3 disposed on one side of the transformer housing 1. A noise reduction mechanism 4 is provided inside the transformer housing 1. A first window 11 is provided through the outer wall of one side of the transformer housing 1, and a second window 12 is provided through the outer wall of the other side of the transformer housing 1. An oil tank 13 is provided through the bottom of the transformer housing 1, and a support base plate 14 is provided at the bottom of the oil tank 13. A fixing mechanism 15 is provided at the bottom of the support base plate 14. The air-cooling device 2 includes a cooling fan 21, a cooling block 22, a cooling plate 23, and a first cooling fan 24. The cooling block 22 is located between and connected to the cooling fan 21 and the cooling plate 23. The first cooling fan 24 is connected to the side of the cooling plate 23 away from the cooling block 22. A dustproof box 25 is provided outside the air-cooling device 2, and the dustproof box 25 is connected through the first window 11. The dustproof box 25 has an air outlet 251 through the outer wall on one side. The cooling fan 21 is located at the first window 11, and the first cooling fan 24 is located at the air outlet 251 of the dustproof box 25. The heat dissipation device 3 includes a heat dissipation window 31, which is arranged in a cuboid structure. A second cooling fan 35 is symmetrically arranged on the outside of the heat dissipation window 31. One end of the outer wall of the heat dissipation window 31 is connected to the inner wall of the second window 12. A first limiting frame 32 is arranged on the inner wall around the heat dissipation window 31. A first limiting rod 33 is connected to the middle of the first limiting frame 32. A dustproof mechanism 34 is arranged on the outer wall of the heat dissipation window 31. The noise reduction mechanism 4 includes a first honeycomb sound insulation board 41, a sound insulation felt 42, a sound insulation cotton 43, and a second honeycomb sound insulation board 44. The first honeycomb sound insulation board 41, the sound insulation felt 42, the sound insulation cotton 43, and the second honeycomb sound insulation board 44 are sequentially pasted and connected together. The outer wall of the first honeycomb sound insulation board 41 away from the sound insulation felt 42 is connected to the inner wall of the transformer box 1.

[0032] It should be noted that in this embodiment, the transformer housing 1 is cooled and ventilated by the air-cooling device 2 and the heat dissipation device 3, so as to prevent the internal parts from being damaged by the high internal temperature of the transformer housing 1 and extend the service life of the transformer housing 1 and its internal parts.

[0033] Furthermore, by setting up the air-cooling device 2, the purpose of reducing the air temperature inside the transformer box 1 is achieved. The cooling chip 23 performs cooling, the cooling block 22 performs cooling, and the cooling fan 21 delivers the low temperature to the inside of the transformer box 1 through the first window 11, thereby enhancing the heat dissipation effect on the main body of the energy-saving distribution transformer.

[0034] Furthermore, the heat dissipation device 3 promptly dissipates the high temperature inside the transformer housing 1. While the heat dissipation device 3 dissipates heat, the dustproof net 345 adsorbs the dust inside the transformer housing 1, protecting the internal parts of the transformer housing 1 and preventing dust accumulation.

[0035] Furthermore, by setting up the noise reduction mechanism 4, the noise generated by the main body of the energy-saving distribution transformer is absorbed, thus reducing the noise and minimizing the impact on the daily lives of surrounding residents.

[0036] Please refer to the appendix carefully. Figure 1 and 2 In another preferred embodiment of the present invention, the fixing mechanism 15 includes a fixing frame 151, a plurality of first bolt fixing holes 152 are uniformly provided on the fixing frame 151, the fixing frame 151 is symmetrically arranged at the bottom of the support base plate 14, and fixing grooves 141 are provided through the top of both sides of the support base plate 14. Fixing screws 142 are provided through the fixing grooves 141, and the fixing screws 142 are connected to the fixing frame 151 through the first bolt fixing holes 152.

[0037] It should be noted that in this embodiment, the fixing mechanism 15 facilitates the connection between the transformer housing 1 and the external support, and the fixing groove 141 facilitates the adjustment of the position of the fixing frame 151, making installation convenient.

[0038] Please refer to the appendix carefully. Figure 1 , 2 In another preferred embodiment of the present invention, the dustproof mechanism 34 includes a dustproof frame 341. One end of the dustproof frame 341 is connected to the inner wall of one side of the heat dissipation window 31 via a pivot 342. A second limiting frame 343 is connected to the outer wall of the dustproof frame 341 near the heat dissipation window 31. A second limiting rod 344 is connected to both ends and the middle of the inner wall of the second limiting frame 343. A dustproof net 345 is pasted inside the second limiting frame 343. A second cooling fan 35 is connected to the inner wall of the dustproof frame 341 away from the second limiting frame 343. When the dustproof frame 341 is closed, it is located inside the heat dissipation window 31, and its outer walls are connected to the inner walls of the heat dissipation window 31. An opening and closing handle 346 is connected to the outer wall of the end of the dustproof frame 341 away from the pivot 342.

[0039] It should be noted that, in this embodiment, while the second cooling fan 35 dissipates the heat inside the transformer housing 1, the dustproof net 345 adsorbs the dust inside the transformer housing 1, protecting the parts inside the transformer housing 1 and preventing dust accumulation.

[0040] Furthermore, the second cooling fan 35 is fixed to the dustproof frame 341. While the second cooling fan 35 dissipates the heat inside the transformer box 1, the dustproof net 345 adsorbs and filters dust. The dustproof net 345 can be easily replaced and cleaned by opening the dustproof frame 341.

[0041] Furthermore, the dustproof frame 341 can be easily opened via the opening and closing handle 346 to replace and clean the dustproof net 345 pasted inside the second limit frame 343, making it convenient to use.

[0042] The specific process of this invention is as follows:

[0043] In use, the mounting slot 141 on the support base plate 14 is connected to the mounting bracket 151 via mounting screws 142. The mounting bracket 151 is then connected to the external support mechanism. The dustproof net 345 is placed inside the second limiting frame 343. The first limiting rod 33 and the second limiting rod 344 limit the dustproof net 345, ensuring it is positioned within the second window 12. The dustproof frame 341 is closed using the opening and closing handle 346. The cooling chip 23 is then connected to the external integrated circuit power supply, and the first cooling fan 24 and the second cooling fan 35 are connected to the external power supply for use. By setting up the air-cooling device 2, the internal air temperature of the transformer tank 1 is reduced, thereby enhancing the heat dissipation effect on the main body of the energy-saving distribution transformer. The heat dissipation device 3 promptly discharges the high temperature inside the transformer tank 1. While the heat dissipation device 3 dissipates heat, the dustproof net 345 adsorbs the dust inside the transformer tank 1, protecting the internal parts of the transformer tank 1 and preventing dust accumulation. By setting up the noise reduction mechanism 4, the noise generated by the main body of the energy-saving distribution transformer is absorbed, reducing noise and thus minimizing the impact on the daily life of surrounding residents.
