[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0025] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:
[0026] A new energy oil-immersed transformer dedicated to solar power generation, including an oil-immersed transformer body 1. A fuel tank 2 is fixedly installed on the right side of the oil-immersed transformer body 1. A first filtering component 3 is arranged at the front end of the fuel tank 2, and the rear end of the first filtering component 3 extends into the interior of the fuel tank 2. A lifting component 4 is arranged at the bottom position inside the fuel tank 2. The lifting component 4 includes a lifting bucket 41. The lifting bucket 41 is fixedly installed at the bottom position inside the fuel tank 2. A rotating rod 42 is movably installed inside the lifting bucket 41. Four groups of rotating plates 43 are fixedly installed on the surface of the rotating rod 42 in an annular array;
[0027] A counterweight 44 is fixedly installed in the clockwise direction of each of the four groups of rotating plates 43. A fuel supply pipe 45 is fixedly installed at the bottom of the rear end of the lifting bucket 41. The fuel supply pipe 45 is communicated with the interior of the oil-immersed transformer body 1. The end of the rotating plate 43 is in contact with the inner wall of the lifting bucket 41. When the rotating plate 43 rotates through the rotating rod 42, it can drive the circulation of the gas inside the lifting bucket 41.
[0028] By adopting the above technical solution, before the oil-immersed transformer body 1 works, it is necessary to inject transformer oil into it first. When injecting transformer oil, first open the hopper cover 22 and inject transformer oil into the fuel tank 2 through the oil injection hopper 21. When injecting transformer oil, since the length of the first oil pipe 231 and the oil injection hopper 21 is short, and the connection between the oil injection hopper 21 and the first oil pipe 231 is arc-shaped, the transformer oil can play a certain buffering role when injecting, thus avoiding the situation of splashing when injecting transformer oil. The transformer oil flows through the oil pipe group 23 to the first filtering component 3, then flows through the first filtering component 3 and the second oil pipe 232 to the second filtering component 5, and finally flows into the lifting component 4 through the second filtering component 5 and the third oil pipe 233. Since the whole third oil pipe 233 is inclined towards the lifting bucket 41, when the transformer oil is injected into the interior of the lifting bucket 41 through the third oil pipe 233, the flow of the liquid will generate a certain impact force, so that the rotating plate 43 inside the lifting bucket 41 rotates through the rotating rod 42. And because the rotating plate 43 is in contact with the inner wall of the lifting bucket 41, the rotating plate 43 will promote the air circulation inside the lifting bucket 41 during the rotation process, thus forming a phenomenon of inhaling air into the third oil pipe 233. The generation of this phenomenon can improve the flow speed of the transformer oil in the oil pipe group 23. The rotating plate 43 rotates in the clockwise direction when rotating through the rotating rod 42, and a counterweight 44 is installed in the clockwise direction of the rotating plate 43, so the rotation speed of the rotating plate 43 can be increased, thereby enhancing the air circulation speed and further improving the flow efficiency of the transformer oil. Finally, the transformer oil will be discharged from the lifting bucket 41 through the fuel supply pipe 45 and injected into the oil-immersed transformer body 1.
[0029] Specifically, such as Figures 1 to 3As shown, the first filtering component 3 includes a filtering box 31, which is fixedly installed at the front end of the fuel tank 2. An oil inlet channel 32 and an oil discharge channel 33 are formed in the filtering box 31 from top to bottom. A roller 35 is movably installed inside the oil inlet channel 32. The oil inlet channel 32 and the oil discharge channel 33 are in a communicating state. A filter screen 34 is fixedly installed at the communicating part of the oil inlet channel 32 and the oil discharge channel 33. Four groups of brush plates 36 are fixedly installed on the surface of the roller 35 in an annular array. The filter screen 34 is inclined backward. When the brush plates 36 rotate through the roller 35, the bristles at their ends can contact the filter screen 34. A set of threaded holes 37 are formed on the left and right sides of the front end of the filtering box 31. The filtering box 31 is installed through the threaded holes 37 and screws. A set of second filtering components 5 are arranged at the rear end of the fuel tank 2. The second filtering component 5 has the same structure as the first filtering component 3 and they are symmetric. The height of the first filtering component 3 is higher than that of the second filtering component 5;
[0030] A fuel injection hopper 21 is fixedly installed on the top of the fuel tank 2. A hopper cover 22 is movably installed on the top of the fuel injection hopper 21. An oil pipeline group 23 is arranged inside the fuel tank 2. The oil pipeline group 23 is composed of a first oil pipeline 231, a second oil pipeline 232 and a third oil pipeline 233. The rear end of the first oil pipeline 231 is fixedly connected to the bottom end of the fuel injection hopper 21. The front end of the first oil pipeline 231 is inserted into the oil inlet channel 32. The front end of the second oil pipeline 232 is inserted into the oil discharge channel 33. The rear end of the second oil pipeline 232 is inserted into the oil inlet channel 32 of the second filtering component 5. The rear end of the third oil pipeline 233 is inserted into the oil discharge channel 33 of the second filtering component 5. The front end of the third oil pipeline 233 is communicated with the lifting bucket 41.
[0031] By adopting the above technical solution, transformer oil is a petroleum-based liquid, and there will be some impurities in the liquid. If the transformer oil is injected into the oil-immersed transformer body 1 without filtration, it may cause the equipment in the oil-immersed transformer body 1 to operate smoothly, and even damage the internal equipment of the oil-immersed transformer body 1. The transformer oil is injected into the oil inlet passage 32 through the first oil pipeline 231. At this time, the transformer oil flowing continuously in the oil inlet passage 32 will pass through the filter screen 34 for filtration. The filtered transformer oil then flows into the second oil pipeline 232 through the oil discharge passage 33, flows into the second filtering component 5 through the second oil pipeline 232, and then flows into the third oil pipeline 233 after being filtered by the filter screen 34 in the second filtering component 5, and finally flows into the lifting bucket 41. By setting the first filtering component 3 and the second filtering component 5, the transformer oil can be double-filtered, improving the filtering quality of the transformer oil and avoiding impurities in the transformer oil. At the same time, a roller 35 and a brush plate 36 are also arranged in the first filtering component 3 and the second filtering component 5. When the transformer oil flows in the oil inlet passage 32, it will impact the brush plate 36. Therefore, the brush plate 36 rotates through the roller 35. When the brush plate 36 rotates, the bristles at its end will contact the filter screen 34. Therefore, the impurities filtered on the filter screen 34 can be cleaned to one side, avoiding the situation of blockage of the filter screen 34 after long-term filtration. By setting the roller 35 and the brush plate 36 in the first filtering component 3 and the second filtering component 5, it can prevent the filter screen 34 from being blocked after long-term filtration.
[0032] Working principle: When in use, first inject transformer oil into the oil-immersed transformer body 1. Open the bucket cover 22 and inject transformer oil through the oil injection bucket 21. The transformer oil flows into the oil inlet channel 32 of the filter box 31 through the oil injection bucket 21 and the first oil pipeline 231. After being filtered by the filter screen 34 in the oil inlet channel 32, it flows into the second oil pipeline 232 through the oil discharge channel 33. At this time, the transformer oil is filtered again by the second filtering component 5 and then flows into the lifting bucket 41 through the third oil pipeline 233. When the transformer oil flows through the first filtering component 3 and the second filtering component 5, it will be filtered by the filter screen 34. At the same time, the flow of the transformer oil can also make the brush plate 36 rotate through the roller 35. When the brush plate 36 rotates, it can clean the impurities filtered on the surface of the filter screen 34, sweep the impurities to one side, and prevent the filter screen 34 from being blocked after long-term filtration. When the transformer oil flows into the lifting bucket 41, it will make the rotating plate 43 rotate through the rotating rod 42. When the rotating plate 43 rotates, it will drive the air in the lifting bucket 41 to flow, resulting in the phenomenon of pumping air through the third oil pipeline 233. Through this phenomenon, the flow rate of the transformer oil in the oil pipeline group 23, the first filtering component 3, and the second filtering component 5 is increased. At the same time, the filtering efficiency of the transformer oil in the first filtering component 3 and the second filtering component 5 is also indirectly increased. Finally, the transformer oil is injected into the oil-immersed transformer body 1 through the oil supply pipe 45. After the oil-immersed transformer body 1 completes the injection of the transformer oil, it can work normally.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
