Description

Technical Field

[0001] The present invention relates to the field of oil-immersed transformers, and more particularly to a transformer explosion-proof protection device suitable for extreme environments. Background Art

[0002] Oil-immersed transformers, also known as transformers, are susceptible to internal arcing caused by short circuits, overvoltage, and other factors, which ionizes the oil and releases various flammable gases. If internal overpressure causes the oil tank to vent or rupture, oxygen can enter, which can instantly cause a fire if exposed to open flames. These gases can also spread the fire to nearby equipment, rapidly spreading the fire and causing an explosion, resulting in significant damage. Transformers typically explode within 5 to 50 milliseconds after the internal tank pressure begins to build, making transformer short circuits extremely destructive.

[0003] In order to solve the above problems, the invention patent application with application publication number CN118430938A discloses an oil-immersed transformer explosion-proof pressure protection device. This patent application realizes the effect of automatic pressure relief of the exhaust gas collection component box by setting an automatic pressure relief component, and the structure is convenient for adsorption treatment of the discharged exhaust gas. However, in rainy weather, rainwater will enter the interior of the exhaust gas collection component through the purification net, and the humid air will come into contact with the hydraulic oil, which will reduce the insulation effect of the hydraulic oil and accelerate the corrosion rate of the internal components of the transformer. There are certain safety hazards, and dust attached to the purification net will reduce the filtration rate. Summary of the Invention

[0013] Furthermore, a pressure relief assembly is provided on one side of the upper surface of the transformer body, and the pressure relief assembly includes a guide tube fixed on one side of the upper surface of the transformer body, the other end of the guide tube is fixedly connected to a spiral tube, the other end of the spiral tube is fixedly connected to a burette, and the other end of the burette extends to the interior of the collection bin.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This solution is equipped with a purification component. When the pressure inside the transformer body reaches a certain threshold, the piston pushes the sealing cover upward. The setting of the sealing cover prevents the activated carbon plate from being exposed to the natural environment for a long time, causing a large amount of dust and impurities to adhere to its surface and cause clogging of the activated carbon plate.

[0019] 2. This solution is equipped with a rainproof mechanism. When gas is discharged in rainy or snowy weather, the rising sealing cover will simultaneously drive the annular frame to move upward from the inside of the filter frame, and move multiple exhaust holes from the inside of the filter frame to expose them to the outside world. The gas is filtered by the activated carbon plate and discharged through multiple exhaust holes. Since the exhaust holes are arranged at an angle, rainwater cannot flow into the inside of the filter frame through the exhaust holes, which can effectively prevent rainwater from entering the inside of the collection bin in rainy weather and mixing with the transformer oil inside the collection bin to affect the secondary use of the transformer oil, thereby avoiding accelerated corrosion of equipment components by moisture.

[0020] 3. This solution is provided with a pressure relief component. The pressure inside the transformer body gradually increases, which will prompt the gas to enter the interior of the guide tube. The gas enters the interior of the spiral tube and moves in a spiral motion, so that the oil-gas mixture fully contacts the side wall of the spiral tube, so that the oil mist gathers on the side wall of the spiral tube. The gas smoothly passes through the spiral tube and the burette into the interior of the collection bin. The oil mist gathers into oil droplets and also enters the interior of the collection bin through the burette, so that the oil in the gas can be fully separated, avoiding the impact of the oil mist on the surrounding environment when it is discharged along with the gas.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 8 A transformer explosion-proof protection device suitable for extreme environments includes a mounting frame 1, a transformer body 5 is fixedly connected to the upper surface of the mounting frame 1, a second terminal 4 and a first terminal 3 are respectively provided on the front and rear sides of the upper surface of the transformer body 5, and heat dissipation fins 2 are fixedly connected to the front and rear sides of the transformer body 5. A liquid oil collection component 7 is provided on one side of the mounting frame 1, and a purification component 6 for exhaust is provided on the liquid oil collection component 7.

[0039] like Figure 3-5 As shown, the purification component 6 includes a mounting cylinder 61 fixed on the liquid oil collection component 7, the upper surface of the mounting cylinder 61 is fixedly connected to a connecting frame 610, the upper surface of the connecting frame 610 is fixedly connected to a filter frame 66, the interior of the mounting cylinder 61 is slidably connected to a piston 611, the upper surface of the piston 611 is fixedly connected to a push rod 612, the top of the push rod 612 is fixedly connected to a sealing cover 62, and the inner surface of the filter frame 66 is fixedly connected to an activated carbon plate 615.

[0040] The outer surface of the sealing cover 62 is axially symmetrically fixedly connected to a fixing plate 63, the lower surface of the fixing plate 63 is fixedly connected to a telescopic rod 69, the outer surface of the filter frame 66 is axially symmetrically fixedly connected to a sleeve plate 64, the outer surface of the telescopic rod 69 is sleeved with a spring 65, the inner surface of the connecting frame 610 is fixedly connected to an electromagnet 613, and the upper surface of the piston 611 is fixedly connected to a metal sheet 614.

[0041] The top of the push rod 612 passes through the interior of the electromagnet 613 and the activated carbon plate 615, and the push rod 612 slides with the electromagnet 613 and the activated carbon plate 615. The telescopic rod 69 passes through the interior of the sleeve plate 64 and slides with each other. The spring 65 is located between the fixed plate 63 and the sleeve plate 64 and is fixed to each other.

[0042] like Figure 3 and Figure 6As shown, the liquid oil collection assembly 7 includes a collection bin 71 fixed to one side of the transformer body 5, a pressure relief pipe 72 is fixedly connected to one side of the collection bin 71, an explosion-proof disk 75 is fixedly connected to the edge of the inner surface of the pressure relief pipe 72, a pressure detection sensor 76 is fixedly connected to the inner surface of the pressure relief pipe 72, a water pump 73 is fixedly connected to the lower surface of the collection bin 71, and return pipes 74 are provided at both the output and input ends of the water pump 73, one return pipe 74 extends to the interior of the collection bin 71, and the other return pipe 74 extends to the interior of the transformer body 5, a nitrogen nozzle 77 is provided at the inner bottom of the collection bin 71, the nitrogen nozzle 77 is connected to the nitrogen system, a one-way valve is connected to the output end of the water pump 73, the one-way valve is connected to the return pipe 74, and the flow direction of the one-way valve is from the collection bin 71 to the interior of the transformer body 5.

[0043] In an extremely high temperature environment, the components inside the transformer overheat, the insulation performance of the insulating material on the components degrades and may even be broken down by the current, causing an arc to be generated, causing the transformer oil to heat up rapidly and produce a large amount of gas. The main components of the gas are hydrogen and methane, causing the internal pressure of the transformer body 5 to increase instantly. Excessive pressure will break the explosion-proof plate 75. At this time, the oil and gas inside the transformer body 5 instantly enter the interior of the collection bin 71 through the pressure relief pipe 72, and the oil and gas mixture enters the interior of the collection bin 71 for oil and gas separation. The pressure detection sensor 76 detects the pressure of the transformer oil, transmits the signal to the terminal, opens the nitrogen control system, fills nitrogen into the interior of the transformer body 5 and the interior of the collection bin 71, and energizes the electromagnet 613. When the oil and gas enter the interior of the collection bin 71, the pressure inside the collection bin 71 increases at the same time, which will push the piston 611 to move upward inside the mounting cylinder 61, and the metal sheet 614 moves with the activity. The plug 611 moves synchronously, and the metal sheet 614 approaches the electromagnet 613 and is attracted by the electromagnet 613, thereby fixing the piston 611. At the same time, the piston 611 pushes the sealing cover 62 upward through the push rod 612, opening the filter frame 66, thereby exposing the activated carbon plate 615. The setting of the sealing cover 62 prevents the activated carbon plate 615 from being exposed to the natural environment for a long time, causing a large amount of dust and impurities to adhere to its surface, resulting in clogging of the activated carbon plate 615. At the same time, it prevents the activated carbon from absorbing too much dust and becoming ineffective, thereby reducing the efficiency of absorbing hydrogen and methane. At this time, the interior of the collection bin 71 is interconnected with the interior of the filter frame 66 and the connecting frame 610. The hydrogen and methane generated by the high temperature of the transformer oil enter the interior of the filter frame 66 through the mounting cylinder 61 and the connecting frame 610, and are purified and absorbed by the activated carbon plate 615, absorbing the hydrogen and methane in the gas, achieving pollution-free emissions, and avoiding the impact of hydrogen and methane on the surrounding environment.

[0044] like Figure 4-5As shown, a rainproof mechanism 67 is provided at the edge of the lower surface of the sealing cover 62 . The rainproof mechanism 67 includes an annular frame 671 fixed at the edge of the lower surface of the sealing cover 62 . A plurality of exhaust holes 672 are evenly opened inside the annular frame 671 .

[0045] The exhaust hole 672 is opened at an angle, and one end of the exhaust hole 672 close to the inner surface of the annular frame 671 is higher than the other end. The annular frame 671 and the filter frame 66 are adapted to each other.

[0046] When the transformer is discharging gas, if it encounters rainy or snowy weather, when the filter frame 66 is discharging gas, raindrops will fall into the inside of the filter frame 66, and enter the inside of the collection bin 71 through the filter frame 66, the connecting frame 610 and the mounting cylinder 61, causing rainwater to mix with the transformer oil. The water in the transformer oil will reduce its insulation performance and increase its conductivity, which may cause equipment failure. Therefore, an annular frame 671 is provided under the sealing cover 62. When the gas is discharged, the sealing cover 62 will rise synchronously with the piston 611, and the sealing cover 62 will simultaneously drive the annular frame 671 to move upward. The frame 671 is moved upward from the interior of the filter frame 66, and the multiple exhaust holes 672 are moved out of the interior of the filter frame 66 to expose it to the outside. The gas is filtered by the activated carbon plate 615 and discharged through the multiple exhaust holes 672. Since the exhaust holes 672 are arranged at an angle, rainwater cannot flow into the interior of the filter frame 66 through the exhaust holes 672. This can effectively prevent rainwater from entering the interior of the collection bin 71 during rainy weather and mixing with the transformer oil in the collection bin 71, affecting the secondary use of the transformer oil, thereby preventing moisture from accelerating corrosion of equipment components.

[0047] When the gas inside the transformer body 5 is exhausted, the pressure inside the transformer body 5 and the collection chamber 71 decreases. Since the electromagnet 613 is not energized and does not generate magnetic force, the piston 611 will not be fixed. As the pressure decreases, the spring 65 in the stretched state will pull the fixing plate 63 and the sealing cover 62 downward, so that the sealing cover 62 returns to its original position to cover and seal the filter frame 66. At the same time, the piston 611 moves to the inside of the mounting cylinder 61 for secondary sealing. When the pressure inside the transformer body 5 reaches a certain threshold, the pressure is automatically relieved and the gas is exhausted to prevent the pressure inside the transformer body 5 from exceeding the mechanical strength of the transformer body 5 and causing an explosion, further improving the safety of the transformer body 5.

[0048] like Figure 6 As shown, a pressure relief assembly 68 is provided on one side of the upper surface of the transformer body 5. The pressure relief assembly 68 includes a flow guide tube 681 fixed on one side of the upper surface of the transformer body 5. The other end of the flow guide tube 681 is fixedly connected to a spiral tube 682. The other end of the spiral tube 682 is fixedly connected to a burette 683. The other end of the burette 683 extends to the interior of the collection bin 71.

[0049] During daily use, the transformer may generate heat, which will cause the transformer oil to slowly heat up and slowly generate gas, which is not enough to break the explosion-proof plate 75. At this time, the gas will gather inside the transformer body 5. When the gas gathers inside the transformer body 5 and reaches a certain volume, there will be a risk of explosion. As the gas increases, the pressure inside the transformer body 5 gradually increases, which will prompt the gas to enter the interior of the guide tube 681. When the gas enters the interior of the spiral tube 682, the gas moves spirally inside the spiral tube 682, so that the oil-gas mixture fully contacts the side wall of the spiral tube 682, so that the oil mist gathers on the side wall of the spiral tube 682, and the gas smoothly passes through the spiral tube 682 and the burette 683 into the interior of the collection bin 71. The oil mist gathers into oil droplets and also passes through the burette 683 into the interior of the collection bin 71, so that the oil in the gas can be fully separated, avoiding the impact of the oil mist on the surrounding environment when it is discharged along with the gas.

[0050] like Figure 7-8 As shown, a breaking up assembly 8 is provided on the inner surface of the collecting bin 71, and the breaking up assembly 8 includes a first annular rack 83 fixed on the inner surface of the collecting bin 71 and support rods 84 fixed around the inner surface of the collecting bin 71. The outer surfaces of the four support rods 84 are slidably connected with a ring 85, and an annular groove 89 is provided on the lower surface of the ring 85. The outer surface of the ring 85 is fixedly connected with a second annular rack 86, and the inner surface of the ring 85 is rotatably connected with a support shaft 810, and the outer surface of the support shaft 810 is evenly and fixedly connected with three grid plates 87.

[0051] A second gear 88 is fixedly connected to one side of the outer surface of the support shaft 810 , a driving motor 81 is fixedly connected to the corner of the top of the collection bin 71 , and a first gear 82 is fixedly connected to the output end of the driving motor 81 .

[0052] The second gear 88 is located on the lower surface of the first annular rack 83 . The second gear 88 and the first annular rack 83 are meshed with each other. The first gear 82 and the second annular rack 86 are meshed with each other. The support rod 84 slides inside the annular groove 89 .

[0053] When the internal pressure of the transformer increases instantly, the oil enters the collection chamber 71 through the pressure relief pipe 72, and the pressure detection sensor 76 transmits a signal to the terminal. The terminal turns on the drive motor 81 to make it work, driving the first gear 82 to rotate. The first gear 82 drives the second annular rack 86 engaged with it to rotate. The second annular rack 86 drives the ring 85 to slide stably on the outside of the support rod 84. The ring 85 drives the grid plate 87 and the second gear 88 to rotate in a circle through the support shaft 810. When the second gear 88 rotates in a circle, it meshes with the first annular rack 83. The second gear 88 and the support shaft 810 rotate, driving the three grid plates 87 to rotate synchronously, so that the grid plates 87 rotate in a circle and rotate around the support shaft 810 at the same time. The transformer oil flows into the collection chamber 71 through the pressure relief pipe 72 and first contacts the rotating grid plates 87, so that the streamlined transformer oil is instantly broken up into small oil droplets, which increases the surface area of ​​the transformer oil. The nitrogen sprayed from the nitrogen nozzle 77 quickly cools the transformer oil droplets. At the same time, the transformer oil and nitrogen combine with each other and reduce the concentration of hydrogen and methane in the collection chamber 71, thereby avoiding explosion in the collection chamber 71.

[0054] Instructions for use: The transformer oil heats up rapidly to produce a large amount of gas, the main components of which are hydrogen and methane, causing the internal pressure of the transformer body 5 to increase instantly. When the pressure reaches a certain level, the explosion-proof disk 75 will be broken. At this time, the oil and gas inside the transformer body 5 instantly enter the collection chamber 71 through the pressure relief pipe 72, and the oil and gas mixture enters the collection chamber 71 for oil and gas separation. The pressure detection sensor 76 detects the pressure of the transformer oil and transmits the signal to the terminal, turning on the nitrogen control system to fill nitrogen into the transformer body 5 and the collection chamber 71, and the electromagnetic When the iron 613 is energized and oil and gas enter the collection chamber 71, the pressure inside the collection chamber 71 increases, pushing the piston 611 upward inside the mounting cylinder 61. The metal sheet 614 moves synchronously with the piston 611. The metal sheet 614 approaches the electromagnet 613 and is attracted by the electromagnet 613, thereby fixing the piston 611. At the same time, the piston 611 pushes the sealing cover 62 upward through the push rod 612, opening the filter frame 66. The oil and gas enter the filter frame 66 through the mounting cylinder 61 and the connecting frame 610, and the hydrogen and methane are purified and absorbed by the activated carbon plate 615.

[0055] An annular frame 671 is provided below the sealing cover 62. When gas is discharged, the sealing cover 62 rises synchronously with the piston 611, and the sealing cover 62 simultaneously drives the annular frame 671 upward from the inside of the filter frame 66, exposing the multiple exhaust holes 672 from the inside of the filter frame 66. The gas is filtered by the activated carbon plate 615 and discharged through the multiple exhaust holes 672. Since the exhaust holes 672 are arranged at an angle, rainwater cannot flow into the filter frame 66 through the exhaust holes 672.

[0056] When the gas accumulates inside the transformer body 5 and reaches a certain concentration, there will be a risk of explosion. As the gas increases, the pressure inside the transformer body 5 gradually increases, which will prompt the gas to enter the inside of the guide tube 681. When the gas enters the inside of the spiral tube 682, the airflow moves in a spiral motion inside the spiral tube 682, so that the oil-gas mixture fully contacts the side wall of the spiral tube 682, so that the oil mist gathers on the side wall of the spiral tube 682, and the gas smoothly passes through the spiral tube 682 and the burette 683 into the inside of the collection bin 71. The oil mist gathers into oil droplets and also passes through the burette 683 into the inside of the collection bin 71, so that the oil in the gas can be fully separated.
