Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and particularly to an oil-immersed transformer with an oil purification structure. Background Technique

[0002] A transformer is an important electrical equipment. During the operation of the transformer, heat is generated when current passes through the coil, so cooling is required. The oil in the oil-immersed transformer serves the purpose of cooling. According to the structure, the oil-immersed transformer can be divided into a core-type transformer and an iron-shell type transformer. When the winding is wrapped around the periphery of the iron core, it is a core-type transformer, and when the iron core is wrapped around the periphery of the winding, it is an iron-shell type transformer. The two are only slightly different in structure and have no essential difference in principle. The oil-immersed transformer mainly consists of an iron core, a winding, an oil tank, an oil conservator, an insulating bushing, a tap changer, a gas relay, etc.

[0003] The oil in the oil-immersed transformer not only plays an insulating role but also undertakes the heat dissipation function, which is crucial for the stable operation of the transformer. However, during long-term operation, the internal components of the transformer work in a high-voltage and high-temperature environment for a long time, and different degrees of wear and aging will occur. For example, the winding insulation material gradually decomposes under the action of electrical stress and thermal stress, and the fibrous or granular substances generated will mix into the oil. The metal debris generated by the electromagnetic vibration of the iron core will also enter the oil. Therefore, it is necessary to filter the oil. The traditional oil purification method of the oil-immersed transformer mainly relies on manually replacing the filter screen regularly for filtration. However, the device cannot automatically clean the filter screen during use. As the filtration time increases, the filter screen will gradually be blocked, resulting in a sharp decline in the filtration efficiency and unable to meet the long-term stable operation of the transformer.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Through the coordinated operation of the liquid supply component and the purification component, the oil inside the transformer can be pumped into the heat dissipation pipe, so that the hot oil can exchange heat with the outside air more fully, speeding up the heat dissipation of the oil. After that, it is filtered through the oil purification box and returned to the transformer through the stretching hose 2, so as to be used stably in a cycle, thereby quickly reducing the oil temperature inside the transformer and ensuring the efficient operation of the transformer. During the heat dissipation, the self-cleaning component is set to automatically clear and collect impurities in the filter holes inside the flexible belt, so that the whole does not need to be replaced and cleaned manually, and can be cleaned automatically, ensuring the sustainable operation of the overall purification and filtration operation, and meeting the long-term stable operation of the transformer;

[0017] 2. When the self-cleaning component is running, it will trigger the cleaning component to run synchronously. Through the operation of the cleaning component, the dust on the outer surface of the heat pipe can be brushed back and forth, thereby ensuring the cleanliness of the heat pipe surface, avoiding the thick dust adhesion affecting the overall heat dissipation effect, and the overall use effect is better;

[0018] 3. When the self-cleaning blockage component is running, the briquetting collection component is started synchronously. Through the cooperation between the two components, the fibrous substances filtered from the surface of the flexible belt can be scraped and collected during use to ensure the overall filtering effect of the flexible belt. At the same time, the collected fibrous substances can be concentratedly squeezed, and at the same time, the quantitative flocculant is sprayed to make the squeezed fibrous substances form long strips and blocks, and finally fall into the storage area on one side of the collection box. As a result, the volume of the fibrous substances is greatly reduced after being squeezed and agglomerated, and the internal storage space of the collection box will not be rapidly reduced, thereby reducing the cleaning frequency of the collection box. At the same time, when it is taken out later, the fibrous impurities after being squeezed and agglomerated form blocks with a certain shape and density. The contact area between this block and the inner wall of the collection box is relatively small, and due to its good integrity, it will not be easily broken or scattered. When taking it out, you only need to use simple tools, such as a shovel or a clamp, to easily take it out of the collection box completely, and the overall cleaning is more convenient and quick.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0036] Embodiment 1: Please refer to Figures 1 - 6 , an oil-immersed transformer with an oil purification structure, including a main transformer housing 1, an auxiliary heat sink 2 installed on one side, and a rotating shaft 3 longitudinally rotatably installed on the outer edge of the other side of the main transformer housing 1. A heat dissipation pipe 4 is fixedly installed on the outer side of one side of the rotating shaft 3. An adjusting assembly is arranged on one side of the bottom end of the rotating shaft 3. A liquid supply assembly is arranged at the input end of the heat dissipation pipe 4. An oil purification box 10 is fixedly installed on the outer side of one side of the output end of the heat dissipation pipe 4. A purification assembly is arranged inside the oil purification box 10. A fixed frame 27 is longitudinally fixedly installed on the outer side of one side of the oil purification box 10.

[0037] The purification component includes four drive shafts 12 and a flexible belt 14. The four drive shafts 12 are all rotatably installed through one side of the oil purification box 10 near the top. The flexible belt 14 is sleeved and attached to the outside of the four drive shafts 12. A number of filter holes 15 are installed through the inside of the flexible belt 14 at equal angles. A water flow driving component is arranged inside the bottom end of the oil purification box 10, and a self-cleaning and blockage prevention component and a pressing block collection component are arranged inside the top end of the oil purification box 10.

[0038] The heat dissipation pipe 4 is arranged in an S shape. The side cross-section of the flexible belt 14 is arranged in a rectangular shape. The output end of the heat dissipation pipe 4 is conductively fixedly connected to a drain pipe head 11. The output end of the drain pipe head 11 is installed through the inside of one side of the top end of the oil purification box 10 located at the bottom of the flexible belt 14.

[0039] Specifically, through the design of the S-shaped heat dissipation pipe 4, the contact area between the heat dissipation pipe 4 and the air is increased. During the rotation process, all parts of the S-shaped heat dissipation pipe 4 can fully contact the air, enabling the hot oil to conduct more sufficient heat exchange with the outside cold air and accelerating the heat dissipation speed of the oil. At the same time, due to the side cross-section of the flexible belt 14 being arranged in a rectangular shape, the liquid discharged from the drain pipe head 11 will directly spray onto the filter holes 15 on the bottom surface of the flexible belt 14 for filtration, while the top surface of the flexible belt 14 is undergoing a cleaning and blockage prevention operation to ensure the stable operation of the device.

[0040] The adjustment component includes a worm gear 5 and a worm 7. The worm gear 5 is fixedly installed through the outside of one side of the bottom end of the rotating shaft 3. The worm 7 is horizontally meshed and connected to the outside of one side of the worm gear 5.

[0041] The liquid supply component includes an oil pump 8 and a first stretching hose 9. The oil pump 8 is fixedly installed on the outside of one side of the rotating shaft 3 through a bracket. The input end of the first stretching hose 9 is fixedly installed through the inside of one side of the main transformer housing 1 near the bottom end, and the output end of the first stretching hose 9 is conductively fixedly connected to the input end of the heat dissipation pipe 4.

[0042] Drive belts 13 are sleeved and attached to the outside between the two ends of the four rotating shafts 3 for transmission. One side of each drive belt 13 is adhesively fixedly connected to one side of the flexible belt 14.

[0043] Specifically, so that the two drive belts 13 on both sides will drive the centrally fixed flexible belt 14 to rotate and change its surface synchronously during rotation.

[0044] The water flow drive assembly includes a guide shell 17 and a rotating rod 19. The guide shell 17 is fixedly installed on the inner wall of the oil purification box 10 near the bottom end. The rotating rod 19 rotates and penetrates the seal installed inside the guide shell 17. The outer surface of the rotating rod 19 located inside the guide shell 17 penetrates and is fixedly installed with a fan blade 18. The oil purification box 10 is located at the top of the guide shell 17 and a V-shaped guide cover 16 is fixedly installed inside. The bottom output end of the guide cover 16 and the top input end of the guide shell 17 are fixedly connected through a conduit. The bottom output end of the guide shell 17 penetrates and is fixedly installed with a stretch hose 36, and the output end of the stretch hose 36 penetrates and is fixedly installed inside one side of the transformer main shell 1 near the top.

[0045] Specifically, the V-shaped arrangement of the air deflector 16 increases the impact force of the oil after passing through the air deflector 16 , thereby ensuring that the oil can impact the fan blades 18 to rotate.

[0046] One end of the rotating rod 19 is rotatably installed on the outside of one side of the oil purification box 10, and the end of the rotating rod 19 located outside the oil purification box 10 is fixedly installed with a limit gear 1 20, and a rotating through end of one of the transmission shafts 12 is fixedly installed with a limit gear 2 21, and the limit gear 1 20 is meshingly connected with the limit gear 2 21.

[0047] The self-cleaning plugging assembly includes a plurality of resistance columns 22, which are all slidably installed in the top side of the oil purification box 10 near the corresponding side filter hole 15, the bottom ends of the plurality of resistance columns 22 are arranged in an arc shape, the tops of the plurality of resistance columns 22 are fixedly installed with a limit block 23, the bottom ends of both sides of the limit block 23 are symmetrically longitudinally provided with two auxiliary rods 24, the bottom ends of the two auxiliary rods 24 are all slidably installed in the top inside of the oil purification box 10, the plurality of resistance columns 22 are all sleeved with a resistance spring 25 near the outside of the top, the two ends of the resistance spring 25 are respectively installed on one side of the limit block 23 and the top of the oil purification box 10, and a collection box 26 is installed in a sliding seal through the inside of one side of the oil purification box 10 near the top.

[0048] In this embodiment, when using this oil-immersed transformer, first install the oil-immersed transformer. At the same time, during installation, the heat dissipation pipe 4 can be rotated to an appropriate angle according to the daily wind direction at the installation location of the transformer to ensure that it is perpendicular to the wind direction and guarantee the heat dissipation effect. During adjustment, the operator only needs to rotate the worm 7 on the mounting seat 6 on one side of the bottom end. By rotating the worm 7, the engaged worm wheel 5 on one side is driven to rotate. By the rotation of the worm wheel 5, the rotating shaft 3 and the heat dissipation pipe 4 on one side are driven to rotate, so that the overall orientation of the heat dissipation pipe 4 can be adjusted conveniently. At the same time, through the meshing self-locking setting of the worm 7 and the worm wheel 5, the situation of rotation due to the resistance of the wind is avoided, and the overall use stability is guaranteed. When the installation and adjustment are completed, during use, the oil pump 8 can be controlled to start. Through the operation of the oil pump 8 and the conduction of the stretching hose 9, the high-temperature oil in the main transformer housing 1 is pumped out and discharged into the heat dissipation pipe 4 to contact the external air for cooling and heat dissipation. Then, the cooled oil enters the oil purification box 10 through the drain pipe head 11, and the cooled oil is sprayed on the filter holes 15 on the bottom surface of the flexible belt 14 to purify and filter the oil to ensure the later use effect. The purified and filtered oil enters the inside of the diversion housing 17 through the diversion cover 16. Through the rotation setting of the rotating rod 19, the oil entering the inside of the diversion housing 17 will impact the fan blade 18, causing the fan blade 18 and the rotating rod 19 to start rotating. Finally, the cooled and filtered oil will return to the inside of the main transformer housing 1 through the stretching hose 2 36 again.

[0049] It should also be noted that when the rotating rod 19 rotates, it will drive the externally mounted limit gear 1 20 on one side to rotate synchronously. When the limit gear 1 20 rotates, it will drive the engaged limit gear 2 21 on one side to rotate synchronously. When the limit gear 2 21 rotates, it will drive one of the transmission shafts 12 to rotate. With the fitting transmission setting of the transmission belt 13, when one transmission shaft 12 rotates, all the transmission shafts 12 will be driven to rotate synchronously, thereby driving the flexible belt 14 to rotate and switch, so that the flexible belt 14 close to the output end of the drain pipe head 11 and the filter holes 15 inside it will continuously switch and change the surface during use, so as to ensure the overall purification and filtration effect without manual switching, which is convenient to use.

[0050] It should also be noted that when the flexible belt 14 is rotating and changing its surface, a number of resistance columns 22 arranged through the top of the oil purification box 10 will be continuously inserted into the interior of the filter hole 15 under the guidance of the auxiliary rod 24 and the rebound and extrusion of the resistance spring 25, so that the impurities in the filter hole 15 can be resisted and discharged, and automatic cleaning can be performed. At the same time, the cleaned impurities will be automatically resisted into the collection box 26, so that the impurities in the filter hole 15 inside the flexible belt 14 can be automatically cleared and collected, so that the whole does not need to be replaced and cleaned manually, and can be cleaned automatically, ensuring the sustainable operation of the overall purification and filtration operation to meet the long-term stable operation of the transformer. At the same time, after a certain period of use, the operator can directly pull the collection box 26 out of the oil purification box 10, centrally process the impurities inside the collection box 26, and then insert it back through the resistance. The single cleaning cycle is long, and the overall use is convenient.

[0051] Example 2: Please refer to Figures 7 - 9 This embodiment further illustrates the first embodiment, where a cleaning component is disposed on one side of the fixing frame 27 .

[0052] The cleaning assembly includes two reciprocating screw rods 31 and two brush rods 33. The two reciprocating screw rods 31 are symmetrically rotatably mounted on the outside of both sides of the fixed frame 27. The two brush rods 33 are symmetrically arranged on the outside of one side of the two reciprocating screw rods 31. The ends of the two reciprocating screw rods 31 close to the middle position of the fixed frame 27 are fixedly mounted with bevel gears 2 30. The top side of the fixed frame 27 close to the bevel gear 2 30 is rotatably mounted with a gear rod 28 through a bracket. The gear end of the gear rod 28 is meshed with one side of the limit gear 1 20, and the other end of the gear rod 28 is fixedly mounted with a bevel gear One 29, bevel gear one 29 is meshedly connected with bevel gear two 30, one side of the two reciprocating screw rods 31 is threadedly connected with a limit slider 32, one end of the limit slider 32 is slidably mounted on the outside of one side of the fixed frame 27, one end of the two brush rods 33 is fixedly connected to one end of the limit slider 32 on the corresponding side, and bristles 34 are adhered and fixed to the outside of one side of the two brush rods 33 close to the heat dissipation pipe 4, and one side of the two brush rods 33 is fixedly installed with a guide ring 35, and the guide ring 35 is slidably mounted on the outside of one side of the heat dissipation pipe 4.

[0053] In this embodiment, when the first limiting gear 20 rotates, it drives the gear rod 28 meshing on one side to rotate synchronously. The rotation of the gear rod 28 drives the first bevel gear 29 on one side to rotate. When the first bevel gear 29 rotates, it drives the two second bevel gears 30 meshing on both sides to rotate synchronously. The rotation of the two second bevel gears 30 drives the reciprocating lead screws 31 fixedly connected on both sides to rotate synchronously. In cooperation with the through-sliding engagement connection between the limiting slider 32 and the fixed frame 27, and at the same time, the limiting slider 32 has a threaded groove, and the limiting slider 32 is threadedly connected to the reciprocating lead screw 31 through the threaded groove. When the reciprocating lead screw 31 rotates, it drives the limiting slider 32 and the brush rod 33 on one side to perform reciprocating motion on one side of the fixed frame 27. At the same time, in cooperation with the installation of the bristles 34 on one side of the brush rod 33, the brush rod 33 drives the bristles 34 to fit on the outer surface of one side of the heat dissipation pipe 4 for reciprocating cleaning motion, so as to be able to reciprocally brush off the dust adhering to the outer surface of the heat dissipation pipe 4, thereby ensuring the cleanliness of the surface of the heat dissipation pipe 4, avoiding the thick adhesion of dust and affecting the overall heat dissipation effect, and the overall use effect is better.

[0054] It should also be noted that through the arrangement of the guiding ring 35 being installed through-sliding on the outside of one side of the heat dissipation pipe 4, the brush rod 33 drives the bristles 34 to perform longitudinal reciprocating motion more smoothly and stably, ensuring the overall cleaning effect.

A discharge slot 45 is provided through the bottom of the processing cylinder 37 near the collection box 26. A partition plate 46 is fixedly installed inside the processing cylinder 37. An installation slot 47 is recessed inside one side of the contact block 44. A driving rod 48 is rotatably installed inside the installation slot 47. One end of the driving rod 48 rotatably penetrates and is installed outside one side of the oil purification box 10. A large gear 50 is fixedly installed through the outside of one side of the output shaft of the stepping motor 38. A small gear 51 is fixedly installed at the rotatable penetration end of the driving rod 48. One side of the large gear 50 is meshed and connected with one side of the small gear 51. An extrusion block 49 is fixedly installed outside one side of the driving rod 48 located inside the installation slot 47. A piston block 52 is slidably and sealingly installed inside one side of the installation slot 47 near the extrusion block 49. A number of one-way liquid discharge nozzles 53 are equally spaced and recessed on the outer surface of one side of the extrusion block 49 located inside the processing cylinder 37. The input ends of the one-way liquid discharge nozzles 53 are all fixedly installed through the inside of one side of the installation slot 47 near the piston block 52. The front sectional views of the adjacent surfaces of the piston block 52 and the extrusion block 49 are both semi-circular. A return spring 54 is fixedly connected and provided between one inner wall of the installation slot 47 and the outer surface of one side of the piston block 52. A one-way liquid inlet valve pipe 55 is fixedly installed through one side of the installation slot 47 located between the one-way liquid discharge nozzles 53 and the piston block 52. A liquid storage tank 56 is fixedly installed on the top of the oil purification box 10 through a bracket. The input end of the one-way liquid inlet valve pipe 55 penetrates and is installed inside one side of the bottom end of the liquid storage tank 56.

[0056] In the present embodiment, when the flexible belt 14 is rotating and switching, its filtering surface will contact the shovel plate 57 on the inner wall of the entry groove 40, so that the fibrous impurities adhering to the filtering surface can be effectively scraped off, thereby ensuring the overall filtering effect of the flexible belt 14. The scraped fibrous impurities fall into the processing cylinder 37 between two squeezing plates 42. At the same time, when in use, the stepper motor 38 can be controlled to rotate intermittently at a time through the existing control module. When the stepper motor 38 is started, the output shaft of the stepper motor 38 is used to drive the rotating rod 39 on one side to rotate synchronously by a certain angle. When the rotating rod 39 rotates by a certain angle, it will drive the external squeezing plate 42 to rotate synchronously. By rotating a certain angle and cooperating with the continuous change of the arc-shaped slope of the resistance block 44, the extrusion plate 42 is compressed toward the inside of the extrusion groove 41 on one side during the process of the resistance movement on one side of the resistance block 44, so that the storage space between the two extrusion plates 42 is reduced, and the fibrous material collected between the two extrusion plates 42 is also compressed and squeezed. After the output shaft of the stepper motor 38 rotates to drive the rotating rod 39 to rotate intermittently at a certain angle, it will synchronously drive the large gear 50 to rotate a certain angle, and the large gear 50 is connected by meshing with the small gear 51, and the gear ratio of the large gear 50 and the small gear 51 is set, so that the large gear 50 rotates a certain angle. When the driving rod 48 rotates, the small gear 51 on one side will be driven to rotate one circle. Through the rotation of the small gear 51, the driving rod 48 and the extrusion block 49 will be driven to rotate one circle inside one side of the installation groove 47. When the driving rod 48 rotates and drives the arc surface of the extrusion block 49 to contact the arc surface of the piston block 52, the piston block 52 is squeezed to move toward the side of the one-way liquid discharge nozzle 53 as a whole, so that the quantitative flocculant originally drawn into the inside of one side of the installation groove 47 is sprayed into the compressed fibrous material through a plurality of one-way liquid discharge nozzles 53, so that the compressed fibrous material is flocculated and agglomerated. When the rotating rod 39 rotates intermittently several times, the compressed block fibrous material is removed from the bottom of the treatment cylinder 37. The fibrous substances are discharged from the discharge groove 45 and fall into the storage area on one side of the collection box 26, so that the volume of the fibrous substances is greatly reduced after being squeezed and agglomerated, and the internal storage space of the collection box 26 will not be rapidly reduced, thereby reducing the cleaning frequency of the collection box 26. At the same time, when taking out later, the fibrous impurities after being squeezed and agglomerated form blocks with a certain shape and density. The contact area between the block and the inner wall of the collection box 26 is relatively small, and due to its good integrity, it will not be easily broken or scattered. When taking it out, it can be easily taken out from the collection box 26 with simple tools, such as a shovel or a clamp, and the overall cleaning is more convenient and quick.

[0057] It should also be noted that when the driving rod 48 drives the arc surface of the extrusion block 49 to rotate and disengage from the arc surface of the piston block 52, one side of the piston block 52 loses the resistance and extrusion. At this time, due to the rebound characteristics of the reset spring 54, the piston block 52 is driven to move back and reset as a whole. At this time, through the conduction between the one-way liquid inlet valve tube 55 and the liquid storage tank 56 and the conduction between the one-way liquid inlet valve tube 55 and the inside of one side of the installation groove 47, the piston block 52 will quantitatively extract the flocculant pre-stored in the liquid storage tank 56 into the inside of one side of the installation groove 47 when moving back, so that the entire device can be used continuously to ensure the flocculation and agglomeration effect of the fiber material in the later stage.

[0058] It should also be noted that when the originally compressed extrusion plate 42 is separated from the resistance block 44, the originally compressed compression spring 43 inside the extrusion groove 41 also rebounds and resets synchronously, thereby driving the extrusion plate 42 on one side to move back and reset synchronously, ensuring that the subsequent rebounded extrusion plate 42 can reach the bottom of the entry groove 40 again for a secondary collection operation, thereby ensuring the overall sustainable use effect.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
