Description

Technical Field

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

[0002] Transformer is an important power equipment. When the transformer is working, the current passing through the coil will generate heat, so it needs to be cooled. The oil in the oil-immersed transformer plays the purpose of cooling. Oil-immersed transformers can be divided into iron core transformers and iron shell transformers according to their structure. The winding is wrapped around the iron core for iron core transformers, and the iron core is wrapped around the winding for iron shell transformers. The two are slightly different in structure, but there is no essential difference in principle. The oil-immersed transformer is mainly composed of iron core, winding, oil tank, oil pillow, insulating bushing, tap changer and gas relay.

[0003] The oil inside the oil-immersed transformer not only plays an insulating role, but also undertakes the heat dissipation function, which is crucial to 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 will experience varying degrees of wear and aging. For example, the winding insulation material gradually decomposes under the action of electrical stress and thermal stress, and the resulting fibrous or granular substances will be mixed into the oil. The metal debris generated by the electromagnetic vibration of the iron core will also enter the oil. Therefore, the oil needs to be filtered. The traditional oil-immersed transformer oil purification method mainly relies on regular manual replacement of the filter for filtration, but the device cannot automatically clean the filter during use. As the filtering time increases, the filter will gradually become blocked, resulting in a sharp drop in filtration efficiency, which cannot meet the long-term stable operation of the transformer.

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.

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.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-Figure 6 An oil-immersed transformer with an oil purification structure includes a transformer main housing 1, an auxiliary heat sink 2 installed on one side, and a rotating shaft 3 longitudinally rotatably installed at the outer edge of the other side of the transformer main housing 1, a heat dissipation pipe 4 is fixedly installed on the outside of one side of the rotating shaft 3, an adjustment component is arranged on one side of the bottom end of the rotating shaft 3, an input end of the heat dissipation pipe 4 is arranged with a liquid supply component, an oil purification box 10 is fixedly installed on the outside of one side of the output end of the heat dissipation pipe 4, a purification component is arranged inside the oil purification box 10, and a fixing frame 27 is longitudinally fixedly installed on the outside of one side of the oil purification box 10.

[0020] The purification component includes four transmission shafts 12 and a flexible belt 14. The four transmission shafts 12 are rotatably installed on one side of the oil purification box 10 near the top. The flexible belt 14 is sleeved and fits on the outside of the four transmission shafts 12. A number of filter holes 15 are installed at equal angles inside the flexible belt 14. A water flow driving component is arranged inside the bottom end of the oil purification box 10, and a self-cleaning component and a briquette collection component are arranged inside the top end of the oil purification box 10.

[0021] The heat dissipation tube 4 is arranged in an S shape, and the side section of the flexible belt 14 is arranged in a rectangular shape. The output end of the heat dissipation tube 4 is connected and fixedly connected with a drainage pipe head 11, and the output end of the drainage pipe head 11 is installed through the oil purification box 10 at the top side of the bottom end of the flexible belt 14.

[0022] Specifically, the S-shaped heat dissipation tube 4 is designed to increase the contact area between the heat dissipation tube 4 and the air. During the rotation process, each part of the S-shaped heat dissipation tube 4 can fully contact the air, allowing the hot oil to have a more complete heat exchange with the external cold air, thereby accelerating the heat dissipation speed of the oil. At the same time, the side profile of the flexible belt 14 is set to be rectangular, so that the liquid discharged from the drain pipe head 11 will be directly sprayed on the filter hole 15 on the bottom surface of the flexible belt 14 for filtration, while the top surface of the flexible belt 14 is performing a clearing operation to ensure the stable operation of the device.

[0023] The adjusting assembly includes a worm wheel 5 and a worm 7. The worm wheel 5 is fixedly installed on the outside of one side of the bottom end of the rotating shaft 3.

The output end of the stretch hose 9 is conductively and fixedly connected to the input end of the heat dissipation pipe 4.

[0025] A transmission belt 13 is sleeved and arranged between the two ends of the four rotating shafts 3 , and one side of the transmission belt 13 is adhered and fixedly connected to one side of the flexible belt 14 .

[0026] Specifically, when the transmission belts 13 on both sides rotate, they will drive the flexible belt 14 fixed in the middle to rotate synchronously and change surfaces.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] In this embodiment, when using the oil-immersed transformer, the oil-immersed transformer is first installed. At the same time, during installation, the heat dissipation pipe 4 can be rotated to a suitable angle according to the daily wind direction of the transformer installation location to ensure that it can be perpendicular to the wind direction and ensure the heat dissipation effect. When adjusting, the operator only needs to rotate the worm 7 on the mounting seat 6 on one side of the bottom end, and the rotation of the worm 7 drives the meshing worm wheel 5 on one side to rotate, and the rotation of the worm wheel 5 drives the rotating shaft 3 and the heat dissipation pipe 4 on one side to rotate, so that the overall direction of the heat dissipation pipe 4 is convenient to adjust. At the same time, the meshing self-locking setting of the worm 7 and the worm wheel 5 can avoid the situation of rotation caused by wind resistance, thereby ensuring the overall stability of use. After the installation and adjustment are completed, the oil pump 8 can be started by control during use. By running the oil pump 8 and connecting the stretch hose 1 9, the high-temperature oil inside the transformer main housing 1 is pumped out and discharged into the heat dissipation pipe 4, where it comes into contact with the external air for cooling and heat dissipation. After that, the dissipated oil enters the oil purification box 10 through the discharge 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 interior of the guide housing 17 through the guide cover 16. Through the rotation setting of the rotating rod 19, the oil entering the guide housing 17 will impact the fan blades 18, so that the fan blades 18 and the rotating rod 19 start to rotate. Finally, the cooled and filtered oil will return to the interior of the transformer main housing 1 again through the stretch hose 2 36.

[0032] It should also be noted that when the rotating rod 19 rotates, it will drive the limit gear 20 installed on one side to rotate synchronously. When the limit gear 20 rotates, it will drive the meshing limit gear 21 on one side to rotate synchronously. When the limit gear 21 rotates, it will drive one of the transmission shafts 12 to rotate. Combined with the fitting transmission setting of the transmission belt 13, when one transmission shaft 12 rotates, it will drive all the transmission shafts 12 to rotate synchronously, thereby driving the flexible belt 14 to rotate and switch, so that the flexible belt 14 near the output end of the discharge pipe head 11 and its internal filter hole 15 will continuously switch and change surfaces during use, so as to ensure the overall purification and filtration effect, without manual switching, and convenient to use.

[0033] 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.

[0034] Example 2: Please refer to Figure 7-Figure 9 This embodiment further illustrates the first embodiment, where a cleaning component is disposed on one side of the fixing frame 27 .

[0035] 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.

[0036] In this embodiment, when the limit gear 1 20 rotates, it will drive the gear rod 28 on one side to rotate synchronously, and the rotation of the gear rod 28 will drive the bevel gear 1 29 on one side to rotate. When the bevel gear 1 29 rotates, it will drive the two bevel gears 2 30 on both sides to rotate synchronously. The rotation of the two bevel gears 2 30 will drive the reciprocating screws 31 fixed on both sides to rotate synchronously, and the limit slider 32 is connected to the fixed frame 27 by sliding engagement. At the same time, the limit slider 32 has a threaded groove, and the limit slider 32 is threadedly connected to the fixed frame 27 through the threaded groove. It is connected to the reciprocating screw rod 31, so that when the reciprocating screw rod 31 rotates, it will drive the limiting slider 32 and the brush rod 33 on one side to reciprocate on one side of the fixed frame 27. At the same time, with the installation of the bristles 34 on one side of the brush rod 33, the brush rod 33 will drive the bristles 34 to fit the outer surface of one side of the heat dissipation tube 4 for reciprocating cleaning movement, so that the dust on the outer surface of the heat dissipation tube 4 can be brushed off reciprocatingly, thereby ensuring the cleanliness of the surface of the heat dissipation tube 4, avoiding the thick adhesion of dust to affect the overall heat dissipation effect, and the overall use effect is better.

[0037] It should also be noted that, by the guide ring 35 being slidably installed on the outside of one side of the heat dissipation tube 4, the brush rod 33 can drive the bristles 34 to perform longitudinal reciprocating motion more smoothly and stably, thereby ensuring the overall cleaning effect.

The input ends of several one-way liquid discharge nozzles 53 are all fixedly installed on the inside of the mounting groove 47 on one side close to the piston block 52. The front cross-section of the adjacent surfaces of the piston block 52 and the extrusion block 49 are both semicircular arc-shaped. A return spring 54 is fixedly connected between the inner wall of one side of the mounting groove 47 and the outer surface of one side of the piston block 52. A one-way liquid inlet valve tube 55 is fixedly installed on the inside of one side of the mounting groove 47 between the one-way liquid discharge nozzle 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, and the input end of the one-way liquid inlet valve tube 55 is installed on the inside of the bottom side of the liquid storage tank 56.

[0039] 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.

[0040] 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, the 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 previously 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.

[0041] 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.
