Description

Technical Field

[0001] This invention belongs to the field of transformer-related technology, specifically a self-cleaning oil-immersed new energy transformer. Background Technology

[0002] An oil-immersed transformer is a power transformer in which the windings and core are immersed in insulating oil. Its core principle is to use the insulating oil as a cooling and insulating medium. The transformer oil effectively carries away the heat generated during operation and dissipates it into the air through the tank casing or heat sinks. Simultaneously, its excellent insulation properties ensure electrical isolation between internal energized components. This structure boasts strong heat dissipation, low cost, large capacity, and long service life, making it the most common and economical transmission and distribution equipment in power systems, widely used in substations, industrial and mining enterprises, and other outdoor applications.

[0003] Patent document CN114628113A discloses an oil-immersed transformer, including a tank, a transformer body, a cooling assembly, an exhaust assembly, and a control assembly. The transformer body is immersed in a cavity filled with insulating oil and fixed to the tank. The transformer body includes an iron core and windings wound around the iron core. The primary and secondary coils of the windings each have at least one high-voltage lead and at least one low-voltage lead. The multiple high-voltage leads and multiple low-voltage leads are electrically connected to high-voltage and low-voltage insulating bushings, respectively. The cooling assembly is installed in the mounting cavity. The exhaust pipe is installed on the upper wall of the tank and forms an exhaust hole. The sealing component includes a connecting part and a sealing part for sealing the exhaust hole.

[0004] Existing oil-immersed transformers have certain shortcomings in use. Oil-immersed transformers mainly achieve internal cooling by circulating oil, which is accomplished through a coil structure for oil transport and cooling. When blockage occurs in the pipeline structure, the oil flow rate of the oil-immersed transformer will decrease or even stop flowing normally, affecting the cooling effect. Secondly, the cooling pipes are an integrated structure, and when there is partial blockage, the entire coil structure needs to be replaced, increasing the maintenance cost of oil-immersed transformers. Summary of the Invention

[0005] This invention provides a self-cleaning oil-immersed new energy transformer, which solves the problem in existing technologies where oil transportation and cooling are achieved through a coil structure. When blockage occurs within the pipeline structure, the oil flow rate in the oil-immersed transformer decreases or ceases to flow normally, thus affecting the cooling effect of the transformer. A self-cleaning, oil-immersed new energy transformer includes a booster installed on one side of the outer surface of an oil tank, with the oil tank and booster connected in a continuous manner. The oil tank is filled with oil, and a pump body for use with the oil tank and booster is fixedly installed on the upper outer surface of the oil tank. The booster includes a high-pressure tank, with a first current controller fixedly installed on one end of the outer surface of the high-pressure tank and a second current controller fixedly installed on the other end of the outer surface of the high-pressure tank. The first and second current controllers are symmetrically arranged.

[0006] As a further technical solution of the present invention, the winding is fixedly installed inside the oil tank, and the iron core is fixedly installed on the outer surface of the winding. The oil-immersed transformer is a transformer that uses the oil to cool the inside of the transformer by immersing the iron core and winding in the oil of the oil tank.

[0007] As a further technical solution of the present invention, an oil conservator is fixedly installed on the upper end of the oil tank on one side of the pump body. The pump body and the oil conservator are connected through each other. The oil conservator is an oil storage tank. The pump body draws the oil out of the oil conservator, so that the oil enters the interior of the oil tank to cool down the iron core and winding. When the oil is discharged from the oil tank, it enters the high-pressure tank of the turbocharger and is transported to the coil assembly through the high-pressure tank. The coil assembly has a coil-shaped structure. During the oil flow, the cooling fan is used to cool down the coil assembly, so that the temperature of the oil is reduced.

[0008] As a further technical solution of the present invention, the second flow controller, the high-pressure tank, and the first flow controller are connected in a continuous manner, and the booster and the coil are connected in a continuous manner. By using the booster, high-pressure unblocking operation of the coil can be realized. When a blockage occurs in the pipeline of the coil, the first flow controller is turned on and the second flow controller is turned off, so that the pump continuously delivers oil to the high-pressure tank of the booster, so that the pressure in the high-pressure tank continuously increases. When the oil pressure in the high-pressure tank reaches a predetermined value, the first flow controller is turned off and the second flow controller is turned on, so that the high-pressure oil in the high-pressure tank is instantly discharged outward through the connecting part, thereby entering the pipeline of the coil. The high-pressure oil impacts the blockage in the pipeline, thereby completing the periodic unblocking operation of the coil.

[0009] As a further technical solution of the present invention, both the second flow controller and the first flow controller include a connecting member and a solenoid valve. The solenoid valve is fixedly installed on the outer surface of one end of the connecting member. The interior of the connecting member has a three-way structure, so that the connecting member can respectively complete the docking operation of the high-pressure tank, the solenoid valve and the connecting pipe.

[0010] As a further technical solution of the present invention, a connecting pipe is fixedly installed at one end of the connecting member, and the high-pressure tank and the coil are connected through the connecting pipe. By using the connecting pipe, the pressurized oil can be transported to the inside of the coil.

[0011] As a further technical solution of the present invention, radiators are fixedly installed on both outer surfaces of the oil tank, and the two sets of radiators are symmetrically arranged. By using the arrangement of the radiators, the oil flowing in the coil can be cooled by air cooling.

[0012] As a further technical solution of the present invention, the outer surface of the radiator is provided with several sets of coils, which are arranged side by side. The oil is transported to the interior of the radiator through the coils to complete the heat dissipation and cooling of the oil.

[0013] As a further technical solution of the present invention, a cooling fan for use with a coil is fixedly installed inside the radiator, and several sets of terminals are provided on the upper outer surface of the oil tank. By using the cooling fan, external air is introduced into the interior of the radiator.

[0014] As a further technical solution of the present invention, the coil assembly includes several sets of main oil pipes and auxiliary oil pipes. The auxiliary oil pipes are fixed between two sets of main oil pipes. The main oil pipes and auxiliary oil pipes are connected and fixed by a combination joint. When a partial blockage occurs in the entire coil assembly, the auxiliary oil pipe in that part can be removed using the combination joint, and the auxiliary oil pipe can be replaced or the main oil pipe can be bypassed.

[0015] The beneficial effects of this invention are as follows: By incorporating a booster, this invention automatically performs intermittent pressure boosting and impacting the oil circuit during the use of the self-cleaning oil-immersed new energy transformer. The pressure generated after the oil is boosted is instantly released, clearing blockages in the pipeline. During operation, the pump draws oil from the oil conservator, allowing it to enter the oil tank for cooling the core and windings. When discharged from the oil tank, the oil enters the high-pressure tank of the booster. When blockage occurs in the coil components' pipeline, the first flow controller is activated and the second flow controller is deactivated, causing the pump to continuously... Oil is supplied to the high-pressure tank of the booster, causing the pressure inside the high-pressure tank to increase continuously. When the oil pressure in the high-pressure tank reaches a predetermined value, the first flow controller is closed and the second flow controller is opened, causing the high-pressure oil in the high-pressure tank to be discharged outward through the connecting part and enter the pipeline of the coil fitting. The high-pressure oil impacts the blockage in the pipeline, thereby completing the periodic unblocking operation of the coil fitting. The oil is transported to the coil fitting through the high-pressure tank. The coil fitting has an overall coil-shaped structure. During the oil flow, the cooling fan is used to cool the coil fitting, thereby reducing the temperature of the oil. By incorporating a coiled tube assembly, this self-cleaning oil-immersed new energy transformer features a combined pipeline structure, making maintenance operations more convenient and reducing maintenance difficulty when the pipeline is blocked. During operation, the radiator allows for air cooling of the oil flowing within the coiled tube assembly. The main oil pipe and auxiliary oil pipe are connected and fixed via a combination joint. When a blockage occurs in a part of the coiled tube assembly, the auxiliary oil pipe in that part can be removed using the combination joint and replaced, or the main oil pipe can be rerouted to keep the entire coiled tube assembly unobstructed.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-4As shown, a self-cleaning oil-immersed new energy transformer includes an oil tank 1 and a booster 2. The booster 2 is installed on one side of the outer surface of the oil tank 1, and the oil tank 1 and the booster 2 are connected in a continuous manner. The interior of the oil tank 1 is filled with oil 16. A pump body 4 for use with the oil tank 1 and the booster 2 is fixedly installed on the upper outer surface of the oil tank 1. The booster 2 includes a high-pressure tank 10. A first current controller 11 is fixedly installed on the outer surface of one end of the high-pressure tank 10, and a second current controller 12 is fixedly installed on the outer surface of the other end of the high-pressure tank 10. The first current controller 11 and the second current controller 12 are symmetrically arranged. The solenoid valves 14 of the first current controller 11 and the second current controller 12 are both controlled by a controller.

[0021] The oil tank 1 has a winding 9 fixedly installed inside, and an iron core 8 is fixedly installed on the outer surface of the winding 9. The oil-immersed transformer is made by immersing the iron core 8 and the winding 9 in the oil body 16 of the oil tank 1, and using the oil body 16 to cool the inside of the transformer.

[0022] An oil conservator 5 is fixedly installed on the upper end of the oil tank 1 on one side of the pump body 4. The pump body 4 and the oil conservator 5 are connected through each other. The oil conservator 5 is an oil storage tank. The oil 16 in the oil conservator 5 is drawn out by the pump body 4 and enters the interior of the oil tank 1 to cool the iron core 8 and winding 9. When it is discharged from the oil tank 1, it enters the high pressure tank 10 of the booster 2 and is transported to the coil component 7 through the high pressure tank 10. The coil component 7 has a coil-shaped structure. During the flow of the oil 16, the cooling fan 18 is used to cool the coil component 7, so that the temperature of the oil 16 is reduced.

[0023] The second flow controller 12, the high-pressure tank 10, and the first flow controller 11 are connected in a continuous manner, as are the booster 2 and the coil 7. The booster 2 allows for high-pressure unblocking of the coil 7. When a blockage occurs in the coil 7's pipeline, the first flow controller 11 is activated and the second flow controller 12 is deactivated, causing the pump 4 to continuously pump oil 16 into the high-pressure tank 10 of the booster 2, thus increasing the pressure within the high-pressure tank 10. When the oil pressure in the high-pressure tank 10 reaches a predetermined value, the first flow controller 11 is deactivated and the second flow controller 12 is activated, allowing the high-pressure oil 16 in the high-pressure tank 10 to be instantly discharged through the connecting piece 13, thereby entering the coil 7's pipeline. The high-pressure oil 16 then impacts the blockage within the pipeline, completing the periodic unblocking operation of the coil 7.

[0024] Both the second flow controller 12 and the first flow controller 11 include a connecting member 13 and a solenoid valve 14. The solenoid valve 14 is fixedly installed on the outer surface of one end of the connecting member 13. The interior of the connecting member 13 has a three-way structure, which allows the connecting member 13 to perform docking operations with the high-pressure tank 10, the solenoid valve 14 and the connecting pipe 15 respectively.

[0025] One end of the connecting member 13 is fixedly installed with a connecting pipe 15. The high-pressure tank 10 and the coil 7 are connected through the connecting pipe 15. By using the connecting pipe 15, the pressurized oil 16 can be transported to the inside of the coil 7.

[0026] Radiators 6 are fixedly installed on both outer surfaces of the oil tank 1. The two sets of radiators 6 are symmetrically arranged. By using the radiators 6, the oil 16 flowing in the coil 7 can be cooled by air cooling.

[0027] The outer surface of the radiator 6 is provided with several sets of coils 7, which are arranged side by side. The oil 16 is transported to the interior of the radiator 6 through the coils 7 to complete the heat dissipation and cooling of the oil 16.

[0028] The radiator 6 is internally fixed with a cooling fan 18 that works with the coil fitting 7. The upper outer surface of the oil tank 1 is provided with several sets of terminals 3. The cooling fan 18 allows external air to be introduced into the radiator 6.

[0029] The coil assembly 7 includes several sets of main oil pipes 19 and auxiliary oil pipes 20. The auxiliary oil pipes 20 are fixed between two sets of main oil pipes 19. The main oil pipes 19 and auxiliary oil pipes 20 are connected and fixed by a combination joint 17. When a blockage occurs in a part of the entire coil assembly 7, the auxiliary oil pipe 20 in that part can be removed using the combination joint 17, and the auxiliary oil pipe 20 can be replaced or the main oil pipes 19 can be bypassed.

[0030] A self-cleaning oil-immersed new energy transformer, when in use, utilizes a booster 2 to automatically and intermittently increase the pressure in the oil circuit. The pressure generated by the increased oil volume 16 is instantly released to clear blockages in the pipeline. During operation, the pump 4 draws the oil volume 16 from the oil conservator 5, allowing it to enter the oil tank 1 for cooling the core 8 and windings 9. When discharged from the oil tank 1, the oil enters the high-pressure tank 10 of the booster 2. When blockage occurs in the pipeline of the coil component 7, the first flow controller 11 is activated and the second flow controller 12 is deactivated, causing the pump 4 to continuously increase the pressure. The oil body 16 is transported into the high-pressure tank 10 of the device 2, causing the pressure inside the high-pressure tank 10 to increase continuously. When the oil pressure in the high-pressure tank 10 reaches a predetermined value, the first flow controller 11 is closed and the second flow controller 12 is opened, so that the high-pressure oil body 16 in the high-pressure tank 10 is instantly discharged out through the connecting part 13, and then enters the pipeline of the coil 7. The high-pressure oil body 16 is used to impact the blockage in the pipeline, thereby completing the periodic unblocking operation of the coil 7. The oil body 16 is transported into the coil 7 through the high-pressure tank 10. The coil 7 has a coil-shaped structure. During the flow of the oil body 16, the cooling fan 18 is used to cool the coil 7, thereby reducing the temperature of the oil body 16. By setting up the coil component 7, the self-cleaning oil-immersed new energy transformer has a combined pipeline structure, which makes maintenance operations more convenient and reduces maintenance difficulty when the pipeline is blocked. During operation, the radiator 6 can be used to cool the oil 16 flowing in the coil component 7 through air cooling. The main oil pipe 19 and the auxiliary oil pipe 20 are connected and fixed by the combination joint 17. When a partial blockage occurs in the entire coil component 7, the auxiliary oil pipe 20 in that part can be removed using the combination joint 17 and replaced, or the main oil pipe 19 can be bypassed to keep the entire coil component 7 unobstructed.

[0031] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
