Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a device for degassing transformer oil. Background Technology

[0002] A transformer is a static electrical device used to convert alternating current (AC) energy of one voltage level to AC energy of another voltage level at the same frequency. It achieves this conversion using the principle of electromagnetic induction without changing the frequency of the electrical energy. Transformer oil degassing is an important maintenance step, primarily to remove dissolved gases, prevent partial discharge, and improve insulation performance. Transformer oil degassing devices are typically used to separate gases and liquids from transformer oil for subsequent testing.

[0003] In existing technologies, online chromatographic degassing methods mainly include membrane separation degassing, vacuum degassing, and headspace degassing. Degassing transformer oil can effectively reduce the risk of transformer failure, extend transformer life, improve transformer performance, and ensure the stability of power supply. Transformer oil degassing devices generally include filtration devices to remove impurities from the oil, thereby improving oil quality, protecting the degassing equipment, and increasing degassing efficiency and speed. However, the filter element in the filtration device needs to be replaced regularly, otherwise it will clog the oil and allow it to enter downstream machines. Removing the filter element is difficult, resulting in slow replacement speed and affecting work efficiency. Therefore, this utility model proposes a transformer oil degassing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for degassing transformer oil to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for degassing transformer oil, comprising: a transformer, a filter mechanism provided on one side of the transformer, the filter mechanism including a pressure cover, and a filter barrel detachably connected to the lower side of the pressure cover.

[0006] The inner surface of the filter barrel is slidably connected to the outer ring surface of the housing. The filter element is fixedly installed on the inner ring surface of the housing. The two sides of the housing are movably engaged with locking blocks. One side of the locking block is fixedly connected to one side of the transverse pressure block, and the other side of the transverse pressure block is fixedly connected to the adjusting plate.

[0007] Preferably, the transformer includes an oil outlet fixedly installed on one side of the bottom and an oil inlet fixedly installed on the other side of the bottom, and an oil pump is provided on one side of the oil outlet.

[0008] Preferably, an oil inlet pump is fixedly installed opposite the oil outlet pump, and a cooling device is fixedly installed between the oil outlet pump and the oil inlet pump. The upper side of the cooling device is connected to the vacuum tank through a solenoid valve.

[0009] Preferably, a vacuum pump is fixedly installed on one side of the vacuum tank, the top of the vacuum tank is fixedly connected to the bottom of the filter barrel through a connecting column, a bent tube is fixedly installed inside the connecting column, and a heating sleeve is fixedly fitted on the outer ring of the connecting column.

[0010] Preferably, a fixing plate is provided on both sides of the top of the heating jacket. One end of the fixing plate is fixedly connected to the outer ring surface of the filter barrel, and a threaded rod is rotatably sleeved on the other end of the fixing plate. A drive sleeve is threaded onto the threaded rod. A connecting seat is fixedly connected to one side of the adjusting plate, and the other side of the adjusting plate is fixedly connected to one side of the transverse pressure block.

[0011] Preferably, a sealing strip is fixedly connected to the other side of the transverse pressure block, the drive sleeve is rotatably connected to one end of the connecting rod by a pin, the other end of the connecting rod is rotatably connected to the connecting seat by a pin, the sealing strip is adapted to the groove opened on the outer ring surface of the filter barrel, a flow guide ring is fixedly connected to the upper surface of the sleeve, and a pull ring is fixedly connected to the filter element.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the filter needs to be replaced, pull the pull ring fixed on the upper side of the filter element, first remove the bolts that connect the pressure cap to the top of the filter element to separate them, and then move the horizontal pressure block horizontally by the back-to-back movement between the adjusting plates on both sides of the filter element. This causes the horizontal pressure block to slide out of the slot on the outer surface of the housing, thus removing the housing from its position. Then, by pulling the pull ring upwards, the filter element and housing can be removed for replacement. This method can better fix the filter element, improve the filtration effect and speed, and does not affect the quick removal of the filter element.

[0014] 2. Place the new filter element into the filter canister. The new filter element is installed by engaging the locking block with the slot on the outer ring of the housing. This locks the new filter element at the top of the filter canister, preventing it from slipping to the bottom and causing difficulty in removal. This facilitates quick removal later and improves work efficiency. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a device for degassing transformer oil, comprising: a transformer 1, a filter mechanism 2 provided on one side of the transformer 1, the filter mechanism 2 including a pressure cover 3, a filter barrel 4 detachably connected to the lower side of the pressure cover 3, the inner surface of the filter barrel 4 being slidably connected to the outer ring surface of the casing 5, a filter element 6 being fixedly installed on the inner ring surface of the casing 5, and locking blocks 7 being movably engaged on both sides of the casing 5, one side of the locking block 7 being fixedly connected to one side of the transverse moving pressure block 8, and the other side of the transverse moving pressure block 8 being fixedly connected to the adjusting plate 9.

[0024] When the filter element 6 inside the filter canister 4 needs to be replaced, pull the pull ring 28 fixed on the upper side of the filter element 6, first remove the bolts installed on the top of the pressure cover 3 and the top of the filter canister 4 to separate them, and then drive the horizontal moving pressure block 8 to move horizontally through the back-to-back movement between the adjusting plates 9 on both sides of the filter canister 4. This causes the horizontal moving pressure block 8 to drive the locking block 7 to slide out of the slot opened on the outer surface of the housing 5, thus no longer limiting the housing 5. Then, by pulling the pull ring 28 upward, the filter element 6 and the housing 5 can be taken out for replacement. Place the new filter element 6 into the filter canister 4, and install the new filter element 6 through the cooperation of the locking block 7 and the slot. This achieves better fixation of the filter element 6, improves the filtration effect and speed, and does not affect the quick removal of the filter element 6.

[0025] Example 2: Based on Example 1, the transformer 1 includes an oil outlet 10 fixedly installed on one side of the bottom and an oil inlet 11 fixedly installed on the other side of the bottom. An oil pump 12 is provided on one side of the oil outlet 10. The oil outlet 10 and the oil inlet 11 are symmetrically arranged on both sides of the bottom of the transformer 1. The oil outlet 10 is connected to the input end of the oil pump 12 through a pipe. The output end of the oil pump 12 is connected to the top of the pressure plate 3 through a connecting pipe. An oil pump 13 is fixedly installed opposite the oil pump 12. A cooling device 14 is fixedly installed between the oil pump 12 and the oil pump 13. The upper side of the cooling device 14 is connected to the vacuum tank 16 through a solenoid valve 15. The input end of the oil pump 13 is connected to the cooling device 14 through the oil inlet pipe, and the output end of the oil pump 13 is connected to the oil inlet interface 11 through the long pipe. The bottom of the vacuum tank 16 is connected to the cooling device 14 through the linear array of solenoid valves 15. A vacuum pump 17 is fixedly installed on one side of the vacuum tank 16. The top of the vacuum tank 16 is fixedly connected to the bottom of the filter barrel 4 through the connecting column 18. A bent pipe 19 is fixedly installed inside the connecting column 18. A heating sleeve 20 is fixedly fitted on the outer ring of the connecting column 18. The vacuum pump 17 installed on one side of the vacuum tank 16 can generate a low-pressure environment in the vacuum tank 16. The connecting column 18 is fixedly supported between the filter barrel 4 and the vacuum tank 16.

[0026] By activating the oil pump 12, the oil outlet 10 draws oil through the pressure cap 3 into the filter tank 4 for filtration. After filtration, the oil flows downwards. Because the connecting column 18 is fitted with several bent tubes 19, the oil flows through these tubes into the vacuum tank 16. A heating jacket 20 is fitted around the connecting column 18 to heat the oil within the bent tubes 19. The bent tubes 19 also slow the oil flow, increasing the heating time. Heating by the heating jacket 20 reduces the viscosity of the oil, making it easier for gas to escape. The vacuum pump 17 creates a low-pressure environment inside the vacuum tank 16. Under this low-pressure environment, the gas dissolved in the oil will escape rapidly, forming bubbles that are then pumped away. After a period of time, the solenoid valve 15 is opened, and the degassed oil is discharged from the vacuum tank 16 and enters the cooling device 14. The cooling device 14 lowers the oil temperature to near room temperature to prevent the oil from causing other problems due to excessive temperature when returning to the transformer 1. Finally, the oil inlet pump 13 is started to return the oil to the oil tank at the bottom of the transformer 1 through the oil inlet port 11, thus completing one cycle.

[0027] Example 3: Based on Example 2, fixing plates 21 are provided on both sides of the top of the heating jacket 20. One end of the fixing plate 21 is fixedly connected to the outer ring surface of the filter barrel 4, and the other end of the fixing plate 21 is rotatably fitted with a threaded rod 22. A drive sleeve 23 is threadedly fitted onto the threaded rod 22. A connecting seat 24 is fixedly connected to one side of the adjusting plate 9, and the other side of the adjusting plate 9 is fixedly connected to one side of the transverse pressure block 8. The fixing plate 21 is fixed to the outer ring surface of the filter barrel 4 and supports the threaded rod 22. The adjusting plate 9 is slidably installed between the two fixing plates 21, thereby limiting its position through the fixing plates 21. The other side of the transverse pressure block 8 is fixed... A sealing strip 26 is fixedly connected. The drive sleeve 23 is rotatably connected to one end of the connecting rod 25 via a pin. The other end of the connecting rod 25 is rotatably connected to the connecting seat 24 via a pin. The sealing strip 26 is adapted to the groove opened on the outer ring surface of the filter barrel 4. A flow guide ring 27 is fixedly connected to the upper surface of the sleeve 5. A pull ring 28 is fixedly connected to the filter element 6. Grooves are opened on both sides of the outer ring surface of the filter barrel 4. The grooves are adapted to the sealing strip 26 fixedly connected to the transverse pressure block 8. The transverse pressure block 8 is slidably connected to the filter barrel 4. The sleeve 5 fixes the filter element 6. The flow guide ring 27 fixedly connected to the upper surface of the sleeve 5 can make the oil flow better to the filter element 6.

[0028] Initially, the locking block 7 is engaged in the slot on the outer surface of the housing 5. When the filter element needs to be replaced, first remove the bolts and nuts installed between the pressure cap 3 and the filter barrel 4 to separate the pressure cap 3 and the filter barrel 4. Pull the pull ring 28, and then rotate the handle fixed to one end of the threaded rod 22 to drive the threaded rod 22 to rotate. The threaded rod 22 has two threads in different directions, which causes the threaded rod 22 to drive the drive sleeve 23 to move. The two drive sleeves 23 move in opposite directions. Under the rotational connection of the connecting rod 25, the connecting seat 24 and the pin, the adjusting plate 9 is pulled away from the filter barrel 4, which drives the transverse pressure block 8 to move synchronously. The transverse pressure block 8 then drives the locking block 7 to disengage. The new filter element 6 is removed by quickly pulling down the pull ring 28 within the slot on the housing 5, thus removing the housing 5 from its position. The new filter element 6 is then placed into the filter barrel 4. The threaded rod 22 is rotated in the opposite direction, and the new filter element 6 is installed through the cooperation of the locking block 7 and the slot. This better secures the filter element 6, improving filtration efficiency and speed, without hindering its rapid removal. The sealing strip 26 installed on one side of the transverse pressure block 8 cooperates with the groove on the outer surface of the filter barrel 4, improving the sealing of the filter barrel 4 and preventing oil spillage. The new filter element 6 is secured at the top of the filter barrel 4, preventing it from slipping to the bottom and causing difficulty in removal, thus facilitating subsequent rapid removal and improving work efficiency.
