[0036] In the transformer for renewable energy power generation cluster of the present invention, when transformer oil flows out from the transformer body 1 and enters the regeneration chamber 2 through the oil inlet pipe 3, it first enters the oil inlet cavity 5. In the oil inlet chamber 5, the transformer oil is initially filtered by the coarse filter component to remove larger impurities and particulate matter, and the oil pressure is increased by the booster component to provide a stable oil flow for subsequent processing; then, the transformer oil enters the heating chamber 6, in which the heating component heats the oil to a suitable temperature to promote the activation and decomposition of pollutants in the oil, creating favorable conditions for subsequent regeneration processing; the heated transformer oil continues to flow and enters the regeneration chamber 7, in which the transformer oil flows from bottom to top, and the oil first enters the regeneration box 11 through the mesh opened on the isolation plate 10 and the regeneration box 11, in which the transformer oil is in close contact with the regeneration layer 12, and the regeneration layer 12 will absorb, decompose or transform harmful substances in the oil, such as oxidation products, moisture, acidic substances, etc., so as to restore the insulation performance and cooling effect of the oil; the regenerated transformer oil then enters the filter chamber 8, and under further filtration by the fine filter component, any residual tiny impurities are removed to ensure the cleanliness of the oil. Finally, the oil enters the cooling chamber 9, and the oil temperature is reduced to a suitable range through the cooling effect of the cooling assembly, and then returns to the transformer body 1 through the oil outlet pipe 4, completing the entire cycle regeneration process; the regeneration layer 12 is composed of granular activated clay, and the colored substances, organic impurities, moisture and acidic substances in the oil are removed through the high adsorption of the activated clay. At the same time, the activated clay is a silicate compound with excellent chemical stability. During the transformer oil regeneration process, it can withstand certain temperature and pressure changes without significant chemical changes or loss of its adsorption performance. On the other hand, the use of granular activated clay helps to provide a contact area between the transformer oil and the activated clay, thereby improving the regeneration effect;
[0037] By installing the regeneration chamber 2 on the transformer body 1 and utilizing the various components inside the regeneration chamber 2, efficient and continuous regeneration of the transformer oil is achieved, which significantly improves the cleanliness and insulation performance of the transformer oil and prolongs the service life of the transformer oil. Through the oil regeneration process, the dependence on fresh transformer oil is reduced, and the frequency and cost of oil replacement are reduced. At the same time, transformer failures and downtime caused by oil quality problems are reduced, the overall operating efficiency and economy of the power generation cluster are improved, transformer failures caused by oil quality problems are reduced, and the power supply reliability and stability of the renewable energy power generation cluster are improved. At the same time, the circulation of transformer oil can be driven, so that the oil is continuously purified and regenerated during the flow process. This circulation not only improves the utilization rate of the oil and the use effect of the transformer oil, but also enhances the self-cleaning ability of the oil, which helps to maintain the long-term stability of the oil quality.
[0038] As a preferred technical solution of the present invention, the boosting component includes a connecting plate 13, an electric oil pump 14 and an oil guide pipe 15. The connecting plate 13 is fixedly connected to the upper part of the oil inlet chamber 5, and multiple electric oil pumps 14 are fixedly connected to the surface of the connecting plate 13. The top of each electric oil pump 14 is fixedly connected to an oil guide pipe 15, and the oil guide pipe 15 is connected to the top of the heating chamber 6. The electric oil pump 14 is located above the coarse filter component.
[0039] Specifically, the electric oil pump 14 can extract the transformer oil from the oil inlet chamber 5 and pressurize it into the subsequent heating and regeneration process to ensure that the oil flow is stable and meets the requirements of the regeneration process, thereby ensuring the stable circulation of the entire transformer oil.
[0040] As a preferred technical solution of the present invention, the coarse filter assembly includes a coarse filter box 16, a coarse filter layer 17 and a first fixed plate 19. The coarse filter box 16 is located between the two isolation plates 10 in the oil inlet chamber 5. The coarse filter layer 17 is fixedly connected to the coarse filter box 16. The first fixed plate 19 is fixedly connected to one side of the coarse filter box 16. The first fixed plate 19 is fixedly connected to the outer wall of the regeneration chamber 2. The upper and lower surfaces of the coarse filter box 16 are provided with meshes.
[0041] Specifically, when the transformer oil flows through the coarse filter box 16, large particles, impurities and suspended matter in the oil are intercepted by the coarse filter layer 17 and remain on its surface or in the pores, thereby preventing these impurities from directly entering precision components such as the electric oil pump 14, reducing the risk of failure of the electric oil pump 14 due to impurity blockage or wear, and also preventing these impurities from directly contacting the regeneration layer 12, preventing a large amount of impurities from directly entering the regeneration layer 12, reducing its regeneration effect, causing damage to the regeneration layer 12, and increasing the service life of the regeneration layer 12; the coarse filter layer 17 is a glass fiber filter element, and the filter element is folded to increase the filtration area. The oil enters from one end of the filter element, and after being filtered by multiple layers of folded filter elements, it flows out from the other end, thereby achieving coarse filtration of the oil.
[0042] As a preferred technical solution of the present invention, the heating assembly includes a heating block 20 and an electric heating wire 23. The heating block 20 is fixedly connected to the middle of the heating chamber 6. A plurality of heating grooves 21 penetrating the heating block 20 are provided on the surface of the heating block 20. An installation groove 22 is provided in the heating block 20. A plurality of electric heating wires 23 are fixedly connected in the installation groove 22. The electric heating wire 23 surrounds the outside of the heating groove 21.
[0043] Specifically, when the electric heating wire 23 is energized, its resistance generates heat, which is transferred to the heating block 20 through the mounting groove 22, thereby heating the transformer oil flowing through the heating groove 21, promoting the activation and decomposition of pollutants in the transformer oil. The high temperature also helps to accelerate the decomposition and removal of oxidation products in the oil, improve the oil's antioxidant properties and stability, create favorable conditions for subsequent regeneration treatment, and improve the regeneration effect of the transformer oil.
[0044] As a preferred technical solution of the present invention, the fine filtration component includes a fine filtration box 24, a ceramic filter element 25, an adsorption layer 26, a filter membrane 27 and a second fixed plate 28. The fine filtration box 24 is located between the two isolation plates 10 in the filter chamber 8. The ceramic filter element 25, the adsorption layer 26 and the filter membrane 27 are fixedly connected in sequence from top to bottom in the fine filtration box 24. The second fixed plate 28 is fixedly connected to one side of the fine filtration box 24. The second fixed plate 28 is fixedly connected to one side of the regeneration chamber 2. The upper and lower surfaces of the fine filtration box 24 are provided with meshes.
[0045] Specifically, the regenerated transformer oil will enter the filter chamber 8, flow from top to bottom, and pass through the ceramic filter element 25, the adsorption layer 26 and the filter membrane 27 in sequence. The ceramic filter element 25 is made of high-purity, porous ceramic materials, which can intercept smaller particles and suspended matter in the oil. Its porous structure also provides a large specific surface area, which is conducive to full contact and filtration between the oil and the filter element; the adsorption layer 26 is used to remove soluble pollutants in the oil, such as water, acidic substances, organic compounds, etc., and is made of materials with strong adsorption capacity, such as activated carbon, molecular sieves, adsorbents, etc. Attached resin, etc.; the filter membrane 27 is made of polytetrafluoroethylene, polypropylene and other materials, and is used to remove tiny particles and colloidal substances remaining in the oil. Its pore size is usually very small and can intercept micron-level or even nano-level impurities. This multi-stage filtration mechanism not only improves the cleanliness of the oil, but also ensures the quality and stability of the oil. The oil with high cleanliness can reduce the sediment and scaling inside the transformer, reduce the wear and failure rate of the transformer, and improve the operating efficiency and reliability of the transformer. The oil with high cleanliness can also extend the service life of the transformer and reduce maintenance costs and downtime.
[0046] As a preferred technical solution of the present invention, the cooling component includes a cooling block 31 and a fan 34. The cooling block 31 is detachably connected to the side of the inner wall of the cooling chamber 9 away from the oil inlet pipe 3. An air inlet 33 is opened at the top of the cooling block 31, and an air outlet 35 is opened at the bottom of the cooling block 31. The air inlet 33 and the air outlet 35 are connected by a guide groove 36. The air inlet 33 and the air outlet 35 are both connected to the outside of the regeneration chamber 2. The fan 34 is fixedly connected in the air inlet 33. A part of the cooling block 31 located in the cooling chamber 9 is provided with multiple cooling grooves 32. The side of the cooling block 31 away from the cooling grooves 32 is fixedly connected to a fourth fixed plate 40, and the fourth fixed plate 40 is fixedly connected to one side of the regeneration chamber 2.
[0047] Specifically, during the transformer oil regeneration process, the heated and regenerated oil enters the cooling chamber 9. At this time, the fan 34 is started, and the external air is sucked into the cooling block 31 through the air inlet 33. The air exchanges heat with the oil flowing through the cooling groove 32 in the guide groove 36, absorbs the heat in the oil, and becomes warm, and is discharged from the air outlet 35. Through this process, the temperature of the oil is effectively reduced, providing suitable temperature conditions for subsequent use.
[0048] As a preferred technical solution of the present invention, the first fixing plate 19, the second fixing plate 28, the third fixing plate 30 and the fourth fixing plate 40 are fixedly connected to the regeneration chamber 2 by bolts 39, and handles 29 are fixedly connected to their surfaces.
[0049] Specifically, when it is necessary to replace the regeneration layer 12, the coarse filter layer 17, the ceramic filter element 25, the adsorption layer 26, the filter membrane 27 or clean the cooling block 31, it is only necessary to loosen the corresponding bolts 39 to easily remove the corresponding fixing plate and the components thereon from the regeneration chamber 2. This detachability greatly simplifies the maintenance process and reduces the maintenance cost; the handle 29 is fixedly connected to the surface of each fixing plate, providing a convenient gripping point for the operator. When removing or installing the fixing plate, the operator can easily apply force through the handle 29, avoiding damage that may be caused by directly applying excessive force to the fixing plate or the bolt 39. By operating with the handle 29, the operator can more stably control the position and direction of the fixing plate, avoiding accidental injuries caused by improper operation.
[0050] As a preferred technical solution of the present invention, a control valve 41 is fixedly connected to the middle of the oil inlet pipe 3, and oil drain ports 42 are opened on the bottom surfaces of the oil inlet chamber 5, the regeneration chamber 7 and the cooling chamber 9, and a sealing cover 43 is threadedly connected to the outer wall of each oil drain port 42.
[0051] Specifically, before replacing the internal components of the regeneration chamber 2, the staff can close the control valve 41, unscrew the sealing cover 43, and drain the transformer oil inside the regeneration chamber 2. After the oil is drained, the components inside the regeneration chamber 2 can be replaced or maintained.
[0052] As a preferred technical solution of the present invention, a heat dissipation mesh plate 37 is fixedly connected to the inner wall of the air outlet 35 , and a waterproof shell 38 corresponding to the position of the fan 34 is fixedly connected to the outer wall of the fourth fixing plate 40 .
[0053] Specifically, the heat dissipation mesh plate 37 can prevent dust, particles and other impurities in the external environment from entering the cooling system through the air outlet 35, thereby maintaining the cleanliness of the system and extending the service life of the equipment; the waterproof shell 38 is fixedly connected to the outer wall of the fourth fixed plate 40 and corresponds to the position of the fan 34. Its main function is to prevent external moisture or humidity from directly contacting the fan 34, thereby preventing the fan 34 from being damaged or its performance degraded due to moisture. This design improves the waterproof performance of the fan 34 and ensures its stable operation in a humid environment.
[0054] As a preferred technical solution of the present invention, a controller 18 is fixedly connected to one side of the regeneration chamber 2, the electric oil pump 14, the electric heating wire 23, and the fan 34 are all electrically connected to the controller 18, and the controller 18 is electrically connected to the transformer body 1.
[0055] Specifically, the controller 18 is used to receive signals from the transformer body 1 or other terminals, and accurately control and supply power to components such as the electric oil pump 14, the electric heating wire 23, and the fan 34 according to preset programs or operating instructions. This centralized control method not only simplifies the operating process, but also improves the response speed and accuracy of the system.
[0056] It is worth noting that the components such as the electric oil pump 14, the electric heating wire 23, and the fan 34 in the present invention are mature products in the prior art, so they are not described in detail here.
