Description
Technical Field
[0001] This invention relates to the technical field of oil conservator moisture absorption devices, and in particular to an oil conservator moisture absorption device for a 345KV ultra-high voltage large-capacity transformer. Background Technology
[0002] The oil conservator moisture absorption device, also known as the transformer breather (moisture absorber), is the only moisture absorption device that is matched with the 345kV main transformer oil conservator. It is a large-capacity main transformer-specific high-flow double-cylinder and high-capacity single-cylinder breather, which is different from the small-specification breather of 10kV and 110kV small transformers. In the existing technology, the oil conservator moisture absorption device absorbs moisture through the desiccant in the drying cylinder inside the device. However, when the desiccant needs to be replaced after a long period of use, the moisture absorption device needs to be replaced or disassembled to replace the desiccant inside. This is not only time-consuming and labor-intensive, but the moisture absorption device cannot perform its moisture absorption function properly for a long time, which may even affect the normal operation of the transformer. Therefore, there are areas for improvement. However, since the nut is installed on the lead screw later, errors can easily occur in the installation of the lead screw and the nut, which will affect the stability of the module's movement. In order to ensure the stable operation of the module, lubricating oil is added to the lead screw for lubrication. This makes it easy for dust in the air to accumulate on the lead screw, shortening the service life of the lead screw and the module, and it is also difficult to clean. Therefore, there are areas for improvement. Summary of the Invention

Transformer oil is contained at the bottom of the venting cavity 13 and the venting cavity 24, and the vent 25 is submerged. The transformer oil in the oil conservator When the oil conservator is cooled and air is drawn out, the gas in the external space enters the air passage chamber 13 through the air passage port 12, passes through the transformer oil and the air passage port 25 into the air passage chamber 24, then enters the air passage chamber 37 through the air passage port 36, and enters the corresponding moisture absorption cylinder 10 from the air passage chamber 317. After being dehumidified by the desiccant in the moisture absorption cylinder 10, the gas enters the oil conservator through the bottom pipe 4, the connecting pipe 5, and the pipeline. When the transformer oil in the oil conservator is heated, the oil conservator exhausts gas outward.

This causes one end of the insertion rod 34 to slide from the lowest positioning groove 31 into the adjacent transmission groove 32. The insertion rod 34 presses against the wall of the transmission groove 32, pushing the transmission column 30 and the connecting column 29 to rotate as a whole. This causes the switching disc 6 and the dehumidifying cylinder 10 to rotate as a whole, switching the dehumidifying cylinder 10 to the dehumidifying position for continued dehumidification.

Several air passage grooves 21 are opened on the top surface of the lifting cylinder 20. The lifting cylinder 20 is not enclosed. The lifting cylinder 20 has several limiting grooves on its side, and each limiting groove has a limiting strip 36 that moves through it. The limiting strip 36 is fixedly set on the inner wall of the air passage cavity 17. The screw 27 rotates through the threaded groove in the middle of the top surface of the lifting cylinder 20, and the screw 27 rotates out of the top of the top cover 3 to install the rotating wheel 28; a fixing ring 23 is set at the bottom of the lifting cylinder 20, and a sealing ring 24 is set at one end of the fixing ring 23. The sealing ring 24 is inserted into the sealing gasket 26 in the corresponding sealing groove 25; a fixing ring 22 is fixedly set on the inner wall of the air passage chamber 3 17, and the lifting cylinder 20 is pressed against the fixing ring 22; after switching the moisture absorption cylinder 10, the screw 27 is rotated by the rotating wheel 28. Under the limiting action of the limiting strip 36, the lifting cylinder 20 moves up and down on the screw 27, and the lifting cylinder 20 presses against the sealing ring 24 and inserts into the sealing gasket 26 in the sealing groove 25 at the top of the moisture absorption cylinder 10, while simultaneously lifting and lowering. The cylinder 20 is pressed against the fixing ring 22 to ensure the air passage chamber 17 and the moisture absorption cylinder 10 are sealed; the hook structure includes: a hook frame 44 set above the side of each moisture absorption cylinder 10; a square groove is opened on the main body 1 of the moisture absorption device, a square block 47 moves through the square groove, a sealing plate 48 is set on the square block 47, and a handle 52 is installed on the sealing plate 48; a hook rod 46 is connected to the bottom of the square block 47, and a hook block 45 is installed at one end of the hook rod 46; a second protrusion 49 is set on one side of the sealing plate 48, a third screw 50 moves through the second protrusion 49, the bottom end of the third screw 50 is fixedly connected to the main body 1 of the moisture absorption device, the top end of the third screw 50 is tightened with a second screw sleeve 51 by a thread, and the bottom end of the second screw sleeve 51 is rotatably set on the second protrusion 49; When the desiccant in the moisture-absorbing cylinder 10 needs to be replaced, switch to the switching position. First, rotate the threaded sleeve 51 on the protrusion 49 to turn the threaded sleeve 51 out from the top of the screw 50. Then, use the handle 52 to pull out the square block 47 and the sealing plate 48 from the square groove. As the square block 47 is pulled out of the square groove, it drives the buckle 46 to insert the buckle block 45 into the buckle frame 44. As the sealing plate 48 moves upward, the moisture-absorbing cylinder 10 is pulled out from the main body 1 of the moisture-absorbing device, and the desiccant in the corresponding moisture-absorbing cylinder 10 is replaced.
[0019] The implementation principle of a moisture-absorbing device for an oil conservator in a 345kV ultra-high voltage large-capacity transformer according to an embodiment of the present invention is as follows: When the transformer oil in the oil conservator cools down and the oil conservator draws air outwards, the gas from the external space enters the air passage chamber 13 through air passage port 12, passes through the transformer oil and air passage port 15 into the air passage chamber 14, then enters the air passage chamber 17 through air passage port 16, and from the air passage chamber 17 into the corresponding moisture-absorbing cylinder 10. After being dehumidified by the desiccant in the moisture-absorbing cylinder 10, the gas enters the oil conservator through the bottom pipe 4, connecting pipe 5, and pipeline. When the transformer oil in the oil conservator heats up, the conservator vents gas outward. The vented gas enters the desiccant 10 through the connecting pipe 5 and the bottom pipe 4, where it is dehumidified by the desiccant. The gas then exits through the third air passage 17, the third air passage 16, the second air passage 14, the second air passage 15, the first air passage 13, and the first air passage 12.

In adjacent transmission grooves 32, the insertion rod 34 presses against the groove wall of the transmission groove 32, pushing the transmission column 30 and connecting column 29 to rotate as a whole, thereby driving the switching disc 6 and the moisture-absorbing cylinder 10 to rotate as a whole, switching the moisture-absorbing cylinder 10 to the moisture-absorbing position to continue the moisture-absorbing work; when the electric push rod 35 continues to drive the lifting ring 33 to move upward, the insertion rod 34 presses against the groove wall of the downward-moving transmission groove 32, which can continue to drive the switching disc 6 to rotate, switching the moisture-absorbing cylinder 10; when the moisture-absorbing cylinder 10 that needs to be replaced with desiccant is switched to the switching position, firstly, on the convex Rotate the second screw sleeve 51 on block 2 49 to turn the second screw sleeve 51 out from the top of the third screw 50. Then use the handle 52 to pull out the square block 47 and the sealing plate 48 from the square groove. During the process of pulling out the square block 47 in the square groove, it drives the buckle 46 to insert the buckle block 45 into the buckle frame 44. As the sealing plate 48 moves upward, the moisture absorption cylinder 10 is pulled out from the main body 1 of the moisture absorption device. The desiccant in the corresponding moisture absorption cylinder 10 is replaced. During the replacement process, the device can continue to perform moisture absorption. The operation is more labor-saving and convenient, and the work efficiency is improved.
