Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to a small transformer breather integrated device that facilitates operation monitoring and maintenance. Background Technology

[0002] The power industry is a leading sector of national industry, and its stable development is the foundation for the sustainable development of the national economy. Transformers are an important component of the power system, and their operating status directly affects the system's safety. With the rapid development of ultra-high voltage and extra-high voltage technologies, the power grid capacity has increased and its coverage has expanded. Its failures can cause significant damage and impact on the power system and users.

[0003] The main function of a transformer breather is to breathe air in response to temperature changes and remove impurities and moisture from the intake air; it is an important device to ensure the stable and reliable operation of the transformer. For a transformer, if the breather malfunctions, it may cause the explosion-proof membrane to rupture, oil leakage, water ingress, or a false oil level.

[0004] The applicant found that: replacing silicone requires disassembling the flange bolts. When working on the high-voltage side, the tool's range of motion does not meet the safety distance, posing a risk of electric shock. Furthermore, during installation and replacement, the installation position is generally at the height of a person's head, requiring one person to disassemble the upper flange while another person supports the bottom, which is inconvenient. In addition, over time, the bolts are prone to rusting, requiring tools and making disassembly difficult, which is extremely inconvenient.

[0005] For example, the transformer breather disclosed in CN115458283A includes a silicone canister, a top cover for sealing the silicone canister, a snap-fit ​​arm, and a first snap-fit ​​assembly. By adopting the above-mentioned technical solution, the first snap-fit ​​assembly drives the silicone canister to rotate, which can flip the silicone canister to a set angle so that the silicone canister can be replaced through the open end of the silicone canister. This simplifies the operation process and improves work efficiency. However, in actual use, according to the prescribed steps, it is still necessary to remove the oil seal cup at the bottom first, then tilt the silicone canister to pour out the old silicone, then wipe the inner wall of the silicone canister, and finally replace it with new silicone.

[0006] More importantly, traditional silica gel changes color after absorbing moisture, indicating excessive humidity. When silica gel absorbs water, it expands in volume (the water absorption rate can reach 40%), indicating that the humidity in the air has exceeded the safe threshold (usually >60%RH), and the silica gel needs to be replaced immediately. However, current technology requires manual observation of the silica gel color change, relying entirely on manual inspection for identification. In large substations, it is difficult to quickly locate abnormal equipment, and manual inspection is often delayed, making it difficult to detect silica gel saturation failure in time. This causes the respirator to continue to operate in a "sick" state, making preventive maintenance impossible and creating safety hazards. Summary of the Invention

[0007] The purpose of this invention is to provide a small transformer breather integrated device that is easy to monitor and maintain during operation, in order to overcome the shortcomings mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a small transformer breather integrated device for easy operation monitoring and maintenance, comprising: a transformer body, an oil level gauge connected to one side thereon, a support frame at the bottom end, and an oil inlet at the top end of the transformer body.

[0009] The oil inlet is connected to a conduit via a flange, and a breather is installed at the end of the conduit. The breather includes:

[0010] A transparent silicone container with a removable top cover that is sealed at the top and a liftable bottom cover that is sealed at the bottom.

[0011] The humidity alarm component located inside the bottom cover includes a silicone expansion drive mechanism and an acoustic alarm. The silicone expansion drive mechanism monitors the expansion of the silicone volume by absorbing moisture in real time and triggers the acoustic alarm.

[0012] The moving component that drives the transparent silicone can to separate from the top and bottom covers includes a first lifting mechanism located on the outside of the silicone can, and a second lifting mechanism that independently drives the transparent silicone can to move up and down.

[0013] Cleaning components integrated into the inner wall of the silicone container;

[0014] in,

[0015] The first lifting mechanism drives the transparent silicone tank and bottom cover to move down to the operating height;

[0016] The second lifting mechanism drives the transparent silicone tank to move upwards separately, exposing the bottom opening of the tank so that the old silicone can be unloaded by gravity, while the cleaning component scrapes away the residue inside the tank.

[0017] The second lifting mechanism drives the transparent silicone tank to move down and reset, and new silicone is filled through the opening at the top of the tank;

[0018] The first lifting mechanism drives the transparent silicone tank and bottom cover to move upward and lock them into the working position.

[0019] The first lifting mechanism lowers the silicone tank and bottom cover to the appropriate operating height simultaneously; the second lifting mechanism lifts the silicone tank separately, exposing the bottom opening to allow the old silicone to be unloaded by gravity, while the cleaning components scrape the tank wall clean; after the tank body is lowered and reset, new silicone is filled in, and finally the whole body is lifted and locked.

[0020] Preferably, the silicone expansion drive mechanism includes:

[0021] A plurality of compression springs are evenly distributed in the inner cavity of the bottom cover. One end of each compression spring is connected to the bottom end of the bottom cover, and the other end is connected to a base plate. Sliding blocks are provided at both ends of the base plate. Sliding cavities corresponding to the sliding blocks are provided on both sides of the bottom cover. A conductive rod is provided at the bottom of each sliding cavity. One end of the conductive rod passes through the bottom end of the bottom cover and is electrically connected to an acoustic alarm, which is located at the bottom end of the bottom cover. A return spring is sleeved on the outside of the conductive rod. The other end of the conductive rod is connected to a first conductive block. A corresponding second conductive block is provided at the bottom end of each sliding block.

[0022] The silicone absorbs water and expands, pushing the base plate downwards. The sliding block compresses the reset spring, causing the second conductive block to contact the first conductive block, thus completing the circuit and triggering an audible alarm.

[0023] Preferably, the first lifting mechanism includes:

[0024] Two first fixing rods are symmetrically fixedly connected to both sides of the top cover, and the outer side of the first fixing rods is provided with a first sliding protrusion;

[0025] Two second fixing rods are symmetrically fixedly connected to both sides of the bottom cover. The inner side of the second fixing rod is provided with a first sliding groove corresponding to the first sliding protrusion.

[0026] The first sliding protrusion moves vertically along the groove of the second fixed rod, ensuring that the silicone can and the bottom cover rise and fall synchronously without deviation.

[0027] Preferably, the second lifting mechanism includes:

[0028] A second sliding groove is provided inside the two first fixed rods;

[0029] The second sliding protrusions are symmetrically arranged on both sides of the transparent silicone can, corresponding to the second sliding groove.

[0030] The silicone can be raised and lowered independently by moving the second sliding protrusion along the groove of the first fixed rod, thus separating it from the bottom cover.

[0031] Preferably, the cleaning component includes:

[0032] Two parallel sliding rods are provided, with one end of each rod vertically fixed to the top cover and the other end fixedly connected to both ends of an annular scraper. The annular scraper is in contact with the inner wall of the transparent silicone can.

[0033] When the silicone tank rises or falls individually, the fixed scraper moves downward or upward relative to the surrounding area, and the annular blade scrapes away the residual silicone from the tank wall.

[0034] Preferably, the bottom side of the transparent silicone can and the bottom cover are respectively provided with a first handle and a second handle, and the outer side of the two second fixing rods are also provided with hooks.

[0035] The transparent silicone container and its bottom cap are raised and lowered by applying force through the handle, and a recycling bag is placed through the hook. The old silicone falls directly into the recycling bag without coming into contact with the air.

[0036] Preferably, the top cover is further provided with a connector, which includes hooks disposed on both sides of the top cover and buckle rings disposed on two second fixing rods corresponding to the hooks.

[0037] Preferably, both the bottom end of the top cover and the top end of the bottom cover are provided with sealing gaskets.

[0038] By compressing and filling the gaps at the top and bottom of the transparent silicone can with sealing gaskets, air and moisture can be prevented from entering.

[0039] Preferably, the respirator further includes an oil seal cup, which is disposed at the bottom of the bottom cover and detachably connected to the bottom cover. A second air vent is provided inside the oil seal cup. One end of the second air vent passes through and is fixed to the bottom plate, and a filter screen is provided at the point of penetration. The other end is connected to the oil seal cup.

[0040] Preferably, the respirator further includes a top plate, both ends of which are slidably disposed on the outside of the sliding rod. A first ventilation tube is provided on the top plate, one end of which passes through the top plate and communicates with the top cover, and the other end of which passes through and is fixedly connected to a pressure plate.

[0041] The gas inside the transformer enters the transparent silicone container through the first vent pipe, and the air is connected between the transparent silicone container and the oil seal cup through the second vent pipe. The filter screen is used to prevent the backflow of silicone particles, thus achieving bidirectional filtration.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] 1. In this invention, a dual lifting mechanism consisting of a first lifting mechanism and a second lifting mechanism is used. The first lifting mechanism simultaneously lowers the silicone can and its bottom cover to an appropriate operating height, and the handle is ergonomically designed, allowing for ground-based operation throughout the maintenance process and avoiding the risk of climbing. The second lifting mechanism separately lifts the silicone can to expose its bottom, allowing the old silicone to be automatically unloaded by gravity. This solves the problem of traditional maintenance requiring climbing to remove bolts, which is time-consuming and leaves silicone residue. The invention eliminates the need to remove or tilt the silicone can; the old silicone can be directly dropped into a hook-suspended recycling bag by vertical movement, the can is self-cleaned to remove all residue, and new silicone can be refilled. This method is simple and convenient.

[0044] 2. In this invention, a silicone expansion drive mechanism, a compression spring, and a conductive trigger are used. When the silicone absorbs moisture and expands, it pushes the base plate down. The sliding block compresses the reset spring, and the second conductive block contacts the first conductive block, thus triggering an acoustic alarm by connecting the circuit. This solves the problem that manual inspection cannot detect silicone saturation in time, which leads to oil deterioration. It also effectively avoids transformer oil contamination accidents caused by silicone failure. Attached Figure Description

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Please see Figures 1-9 One embodiment provided by the present invention:

[0057] A small transformer breather integrated device for easy operation monitoring and maintenance includes a transformer body 1, with an oil level gauge 11 connected to one side and a support frame 12 at the bottom. An oil inlet 13 is located at the top of the transformer body 1, and the oil inlet 13 is connected to a conduit 2 via a flange. A breather 3 is installed at the end of the conduit 2. The breather 3 includes:

[0058] A transparent silicone container 31, with a removable top cover 4 and a retractable bottom cover 5 sealed at the bottom;

[0059] The humidity alarm component located inside the bottom cover 5 includes a silicone expansion drive mechanism 6 and an acoustic alarm 7. The silicone expansion drive mechanism 6 monitors the moisture absorption volume expansion of the silicone in real time and triggers the acoustic alarm 7.

[0060] The moving parts that drive the transparent silicone can 31 to separate from the top cover 4 and the bottom cover 5 include a first lifting mechanism 8 located on the outside of the silicone can and a second lifting mechanism 9 that independently drives the transparent silicone can 31 to move up and down.

[0061] Cleaning components integrated into the inner wall of the silicone container;

[0062] in,

[0063] The first lifting mechanism 8 drives the transparent silicone tank 31 and the bottom cover 5 to move down to the operating height;

[0064] The second lifting mechanism 9 drives the transparent silicone tank 31 to move upwards separately, exposing the bottom opening of the tank so that the old silicone can be unloaded by gravity, while the cleaning component scrapes away the residue inside the tank.

[0065] The second lifting mechanism 9 drives the transparent silicone tank 31 to move down and reset, and new silicone is filled through the opening at the top of the tank;

[0066] The first lifting mechanism 8 drives the transparent silicone tank 31 and the bottom cover 5 to move upward and lock them to the working position.

[0067] In this embodiment, the traditional process addresses the shortcomings of replacing silicone sealant, which requires disassembling flange bolts. When working on the high-voltage side, the tool's range of motion does not meet the safety distance, posing a risk of electric shock. Furthermore, during installation and replacement, the installation position is generally at the height of a person's head, requiring one person to disassemble the upper flange while another person supports the bottom, making the operation inconvenient. In addition, over time, the bolts are prone to rusting, requiring tools and becoming difficult to disassemble, which is extremely inconvenient.

[0068] This solution employs a dual-lifting mechanism. The first lifting mechanism 8 drives the tank and bottom cover 5 to move synchronously to an operating height of 1.2m. The second lifting mechanism 9 separately lifts the transparent silicone tank 31, exposing the bottom opening for gravity unloading of the old silicone. Simultaneously, cleaning components are scraped to remove residue from the tank walls. After the tank descends and resets, it is filled with new silicone and then raised and locked as a whole. This solution solves the problems of traditional maintenance requiring high-altitude bolt removal and tilting of the tank to empty the silicone, which are dangerous and leave significant residue. It allows for maintenance to be completed with one hand on the ground, reducing silicone residue and avoiding the risks of working at height.

[0069] Please see Figure 3 and Figure 4 In this embodiment, the silicone expansion driving mechanism 6 includes: a plurality of compression springs 61 evenly distributed in the inner cavity of the bottom cover 5, one end of the plurality of compression springs 61 being connected to the bottom end of the bottom cover 5, and the other end being connected to a base plate 62, the two ends of the base plate 62 being provided with sliding blocks 63, the two sides of the bottom cover 5 being provided with sliding cavities 64 corresponding to the sliding blocks 63, the bottom of the sliding cavity 64 being provided with a conductive rod 65, one end of the conductive rod 65 penetrating the bottom end of the bottom cover 5 and electrically connected to a sound alarm 7, the sound alarm 7 being located at the bottom end of the bottom cover 5; a return spring 66 being sleeved on the outside of the conductive rod 65, the other end of the conductive rod 65 being connected to a first conductive block 67, and the bottom end of the sliding block 63 being provided with a corresponding second conductive block 67.

[0070] Traditional silica gel, when it absorbs moisture and changes color, indicates that the humidity is too high. When silica gel absorbs water, it expands in volume (the water absorption rate can reach 40%), indicating that the humidity in the air has exceeded the safe threshold (usually >60%RH), and the silica gel needs to be replaced immediately. However, the current technology requires people to come close to observe the color change of the silica gel. It relies entirely on manual inspection and identification, which makes it difficult to quickly locate abnormal equipment in large substations. Manual inspection is often lagging behind.

[0071] In this embodiment, the silicone absorbs moisture and expands, pushing the base plate 62 downward. The sliding block 63 compresses the reset spring 66, and the second conductive block 67 contacts the first conductive block 67, thus realizing the circuit conduction and triggering an 85dB sound alarm. This method is low-cost and highly effective, solving the problem that manual inspections are difficult to detect silicone saturation in a timely manner, and that the lag leads to oil quality deterioration.

[0072] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 In this embodiment, the first lifting mechanism 8 includes: two first fixing rods 81, which are symmetrically fixedly connected to both sides of the top cover 4, and the outer side of the first fixing rods 81 is provided with a first sliding protrusion 82; two second fixing rods 83, which are symmetrically fixedly connected to both sides of the bottom cover 5, and the inner side of the second fixing rods 83 is provided with a first sliding groove 84 corresponding to the first sliding protrusion 82.

[0073] The second lifting mechanism 9 includes: a second sliding groove 92 disposed inside the two first fixed rods 81; and second sliding protrusions 93 symmetrically disposed on both sides of the transparent silicone can 31, corresponding to the second sliding groove 92.

[0074] The transparent silicone can 31 and the bottom cover 5 are respectively provided with a first handle and a second handle on the bottom side, and hooks are also provided on the outer side of the two second fixing rods 83.

[0075] The cleaning component includes two parallel sliding rods 101, one end of which is vertically fixed to the top cover 4, and the other end is fixedly connected to both ends of the annular scraper 102. The annular scraper 102 is in contact with the inner wall of the transparent silicone tank 31.

[0076] The top cover 4 is also provided with a connector 14, which includes hooks 141 disposed on both sides of the top cover 4, and buckle rings 142 disposed on the two second fixing rods 83 corresponding to the hooks 141.

[0077] The respirator 3 also includes a top plate 19, both ends of which are slidably disposed on the outside of the sliding rod 101. A first ventilation pipe 20 is provided on the top plate 19. One end of the first ventilation pipe 20 passes through the top plate 19 and communicates with the top cover 4. The other end of the first ventilation pipe 20 passes through and is fixedly connected to a pressure plate 21.

[0078] Both the bottom of the top cover 4 and the top of the bottom cover 5 are provided with sealing gaskets 15.

[0079] In this embodiment, the working principle of the linkage between the moving part and the cleaning part is as follows:

[0080] like Figure 8 As shown, when the second handle is pulled down, the second fixing rod 83 moves the first sliding groove 84 downward, and the first sliding protrusion 82 of the first fixing rod 81 slides vertically along the first sliding groove 84, causing the transparent silicone can 31 and the bottom cover 5 to descend synchronously to the operating height, while preventing the can from tilting.

[0081] like Figure 9As shown, the unloading and cleaning are then completed simultaneously by raising the tank separately: the first handle is lifted, and the second sliding protrusion 93 of the transparent silicone tank 31 moves upward along the second sliding groove 92 of the first fixed rod 81, so that the tank is separated from the stationary bottom cover 5, the bottom opening of the tank is exposed, and the old silicone is unloaded by gravity and falls into the recycling bag suspended by the hook; or the material recycling box can be placed directly under the respirator 3 for recycling.

[0082] As the transparent silicone tank 31 rises, the annular scraper 102 moves downward relative to the inner wall of the tank. The scraper blade is made of polytetrafluoroethylene or a wiping sponge to scrape the tank wall, peeling off the residual silicone and wiping the inner wall; thus achieving simultaneous unloading and cleaning.

[0083] The can body descends and resets, then is filled with new silicone: Press down the first handle, and the transparent silicone can 31 moves down along the second sliding groove 92. The annular scraper 102 moves upward relative to it, scraping twice, and the can body descends to the top of the bottom cover 5.

[0084] Pull up the top plate 19 and the pressure plate 21, and fill in new silicone through the opening at the top of the can. Then, press down and seal the new silicone particles in the transparent silicone can 31 through the pressure plate 21.

[0085] like Figure 7 As shown, when the second handle is lifted, the bottom cover 5 moves the transparent silicone container 31 to the lower end of the top cover 4. The hook 141 of the top cover 4 engages with the buckle ring 142 of the second fixing rod 83 to achieve a wedge-shaped locking buckle connection. This is existing technology and will not be elaborated on in detail as it is only for demonstrating the connection relationship. At the same time, the sealing gaskets 15 set at the bottom of the top cover 4 and the top of the bottom cover 5 achieve a firm seal and lock with the transparent silicone container 31.

[0086] Please see Figure 2 , Figure 4 , Figure 8 and Figure 9 The respirator 3 also includes an oil seal cup 16, which is disposed at the bottom of the bottom cover 5 and is detachably connected to the bottom cover 5. It can be connected by a threaded connection using existing technology. It is not the focus of improvement of this technical solution, so it will not be described in detail.

[0087] The oil seal cup 16 is provided with a second vent pipe 17. One end of the second vent pipe 17 passes through and is fixed to the bottom plate 62, and a filter screen 18 is provided at the passage. The other end is connected to the oil seal cup 16.

[0088] The first vent pipe 20 connects the transformer gas to the transparent silicone canister 31, and the second vent pipe 17 connects the silicone canister gas to the oil seal cup 16. The filter screen 18 prevents the backflow of silicone particles, thus avoiding the backflow of particles that could block the breathing passage and cause pressure imbalance.

[0089] Working principle:

[0090] Pressure balancing and dehumidification: The gas inside the transformer enters the transparent silica gel tank 31 through the first vent pipe 20. After the silica gel absorbs the moisture, the dry air enters the oil seal cup 16 through the second vent pipe 17. The oil further filters dust and blocks the back seepage of external moisture, thus achieving bidirectional dehumidification and pressure balancing.

[0091] Real-time alarm for excessive humidity: When the silica gel absorbs moisture and expands to the preset threshold, it pushes the base plate 62 to move down, the sliding block 63 compresses the reset spring 66, the second conductive block 67 contacts the first conductive block 67, the circuit is connected and triggers the sound alarm 7, so that the staff can respond in time.

[0092] Pulling down the second handle causes the second fixing rod 83 to move the first sliding groove 84 downwards. The first sliding protrusion 82 of the first fixing rod 81 slides vertically along the first sliding groove 84, causing the transparent silicone can 31 and the bottom cover 5 to descend synchronously to the operating height. Pulling up the first handle causes the second sliding protrusion 93 of the transparent silicone can 31 to move upwards along the second sliding groove 92 of the first fixing rod 81, separating the can from the stationary bottom cover 5 and exposing the bottom opening. The old silicone is unloaded by gravity and falls into the recycling bag suspended by the hook. When the transparent silicone can 31 rises, the annular scraper 102 moves downwards relative to the inner wall of the can, peeling off the residual silicone and wiping the inner wall. Unloading and cleaning are completed simultaneously.

[0093] Press down the first handle, and the transparent silicone container 31 moves down along the second sliding groove 92. The annular scraper 102 moves up and scrapes twice, and the container descends to the top of the bottom cover 5. Pull up the top plate 19 and the pressure plate 21, and fill new silicone into the container through the opening at the top. Then, the pressure plate 21 presses down and seals the new silicone particles in the transparent silicone container 31. Finally, lift up the second handle, and the bottom cover 5 moves the transparent silicone container 31 up to the lower end of the top cover 4. The hook 141 of the top cover 4 engages with the buckle ring 142 of the second fixing rod 83 to achieve a wedge-shaped locking buckle connection. At the same time, the sealing gaskets 15 set at the bottom end of the top cover 4 and the top end of the bottom cover 5 achieve a firm seal and lock with the transparent silicone container 31.

[0094] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
