Description

Technical Field

[0001] This invention belongs to the field of transformer technology, and specifically relates to a dry-type transformer. Background Technology

[0002] Dry-type transformers are a type of transformer that does not require insulating oil and relies on air cooling. Due to their safety and environmental protection characteristics, they are widely used in many fields. They achieve voltage transformation based on the principle of electromagnetic induction. Their core structure includes an iron core (providing the magnetic circuit), windings (achieving electromagnetic conversion), insulation system (ensuring electrical safety), temperature control system (monitoring and protecting equipment), and cooling system (natural / forced air cooling). They are characterized by safety and environmental protection (no risk of oil leakage), easy maintenance (no oil treatment required), stable operation (strong short-circuit resistance), low noise, and energy saving. They are widely used in high-rise buildings, subways, factories, and other scenarios with high requirements for fire prevention and environmental protection.

[0003] Dry-type transformers mostly use natural or forced air cooling. Natural cooling is achieved through heat dissipation of heat between the windings and the core and air convection. Forced air cooling is achieved by adding a fan to accelerate airflow and improve heat dissipation efficiency.

[0004] Currently, regardless of whether it's natural wind cooling or forced air cooling, dust filters are required to reduce the entry of dust and fibers. However, dust filters can only be cleaned during regular transformer maintenance, and even then, professional cleaning tools are needed. Cleaning is particularly complex in humid environments. At present, human resources are becoming increasingly scarce, leading to increased cleaning costs and longer cleaning intervals. If the filter is not cleaned for a long time, the filtration effect will decrease significantly, and a large amount of dust will enter the transformer with the air, accumulating in winding gaps, fan blades, and other areas. The accumulation of dust can even block air ducts, significantly reducing the transformer's heat dissipation efficiency.

[0005] Therefore, it is necessary to provide a dry-type transformer to address the aforementioned technical problems.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0033] like Figures 1 to 9 As shown, a dry-type transformer in one embodiment of the present invention includes: a dry-type transformer body 1, a pair of rotary cleaning mechanisms 2, a pair of positioning power components 3, and an injection cleaning mechanism 4. The pair of rotary cleaning mechanisms 2 are slidably installed inside the dry-type transformer body 1. Each rotary cleaning mechanism 2 includes a filter lifting component 21, a synchronization component 22, and a pair of cleaning components 23. The filter lifting component 21 is slidably installed inside the dry-type transformer body 1, the synchronization component 22 is fixedly installed on one side of the dry-type transformer body 1, and the cleaning components 23 are rotatably installed inside the dry-type transformer body 1.

[0034] The filter lifting assembly 21 includes: a lifting filter 211, a pair of lifting fixing ears 212, a pair of lifting threaded rods 213, and a lifting driven bevel gear 214. The lifting filter 211 is slidably installed inside the dry-type transformer body 1. The lifting filter 211 filters the air intake of the dry-type transformer body 1, reducing the probability of dust entering the dry-type transformer body 1 and improving the cleanliness inside the dry-type transformer body 1. The lifting fixing ears 212 are fixedly installed on one side of the lifting filter 211 and can drive the lifting filter 211 to slide, improving the lifting filter 211's efficiency. The stability of the lifting filter 211 is improved, reducing the chance of tilting and making the lifting of the lifting filter 211 more controllable. The lifting threaded rod 213 is located on one side of the lifting filter 211 and can drive the lifting fixing ear 212, providing corresponding power for the lifting of the lifting fixing ear 212 and improving the controllability of the lifting fixing ear 212. The lifting driven bevel gear 214 is fixedly installed at one end of the lifting threaded rod 213 and can be driven by the synchronous power active bevel gear 223 to rotate, providing corresponding power for the lifting of the lifting fixing ear 212.

[0035] The cleaning assembly 23 includes: a rotating cleaning shaft 231, a rotating cleaning mounting plate 232, a rotating cleaning brush 233, and a rotating cleaning driven pulley 234. The rotating cleaning shaft 231 is rotatably mounted inside the dry-type transformer body 1. The rotating cleaning shaft 231 can drive the rotating cleaning mounting plate 232 to rotate, providing corresponding power for the rotation of the rotating cleaning brush 233. The rotating cleaning mounting plate 232 is fixedly mounted on the rotating cleaning shaft 231 and can clean the lifting filter screen 211, reducing the dust adhering to the surface of the lifting filter screen 211 and improving the cleanliness of the lifting filter screen 211. The rotating cleaning brush 233 is fixedly mounted on one side of the rotating cleaning mounting plate 232 and can be mounted on the rotating cleaning mounting plate 232. It is driven by the rotating cleaning mounting plate 232 to rotate and clean the lifting filter screen 211. The rotating cleaning driven pulley 234 is fixedly mounted on the side of the rotating cleaning shaft 231 away from the rotating cleaning brush 233 and can provide power to the rotating cleaning shaft 231, enabling the rotating cleaning shaft 231 to rotate.

[0036] A pair of positioning power components 3 are fixedly installed on one side of the dry-type transformer body 1.

[0037] The injection cleaning mechanism 4 is fixedly installed inside the dry-type transformer body 1. The injection cleaning mechanism 4 includes a flushing component 41, an injection component 42, a pair of dehumidification components 43 and a pair of efficiency enhancement components 44. The flushing component 41 is fixedly installed inside the dry-type transformer body 1, the injection component 42 is fixedly installed on the lower side of the dry-type transformer body 1, the dehumidification component 43 is fixedly installed inside the dry-type transformer body 1, and the efficiency enhancement components 44 are located on the lower side of the dehumidification component 43.

[0038] The dry-type transformer is used as follows: When the filter lifting assembly 21 needs cleaning, the synchronization assembly 22 controls the filter lifting assembly 21 to descend, providing the corresponding power for the descent. At this time, the cleaning fluid in the injection assembly 42 is injected into the flushing assembly 41, which flushes the filter lifting assembly 21. Simultaneously, the cleaning assembly 23 cleans the filter lifting assembly 21, reducing dust adhesion on its surface and improving its cleanliness. Meanwhile, the positioning power assembly 3 can... The cleaning component 23 is powered and can be controlled to rotate synchronously, providing better cleaning efficiency for the filter lifting component 21. After cleaning, the filter lifting component 21 rises. At this time, the filter lifting component 21 drives the dehumidification component 43 to rotate. The dehumidification component 43 cleans the water droplets on the filter lifting component 21, reducing the chance of water vapor entering the dry transformer body 1. The efficiency enhancement component 44 can keep the dehumidification component 43 dry and improve the moisture absorption efficiency of the dehumidification component 43 on the filter lifting component 21.

[0039] like Figures 1 to 5 As shown, the lifting threaded rod 213 passes through the lifting fixing ear 212, which facilitates the installation of the lifting threaded rod 213, improves its balance, and reduces the probability of it detaching. Simultaneously, when the lifting threaded rod 213 rotates, it can synchronously displace the lifting fixing ear 212, allowing the lifting fixing ear 212 to be raised and lowered under the control of the lifting threaded rod 213. This enhances the controllability of the lifting fixing ear 212. The lifting threaded rod 213 and the lifting fixing ear 212 are matched; the lifting threaded rod 213 can control the lifting fixing ear 212 through its own rotation, thus improving the lifting fixing ear 212's height and position. To improve the smoothness of lifting and lowering, the dry-type transformer body 1 has a lifting groove that matches the lifting filter 211, which improves the stability of the lifting filter 211, reduces the chance of air leakage from the gaps, and improves the cleanliness inside the dry-type transformer body 1. The dry-type transformer body 1 also has a limiting groove that matches the lifting fixing ear 212, which improves the balance of the lifting fixing ear 212, reduces the chance of the lifting fixing ear 212 tilting, and improves the stability of the lifting fixing ear 212, which in turn further improves the balance of the lifting filter 211. The lifting threaded rod 213 is set through the dry-type transformer body 1, which facilitates the installation of the lifting threaded rod 213 and allows the lifting threaded rod 213 to better control the lifting fixing ear 212 to lift and lower.

[0040] like Figures 1 to 3As shown, the lifting threaded rod 213 matches the lifting fixed ear 212. A lifting sealing plate 215 is fixedly installed on the lower side of the lifting filter screen 211, which can seal the cleaning groove on the lower side of the lifting filter screen 211, reducing the entry of water vapor from the lower side of the lifting filter screen 211 into the lifting groove where the lifting filter screen 211 is located, thus improving the service life of the lifting filter screen 211. At the same time, it reduces water vapor leakage and improves the efficiency of the cleaning fluid. A sealing groove matching the lifting sealing plate 215 is carved inside the dry-type transformer body 1, which can be placed on the lifting sealing plate 215 and can be matched with the lifting sealing plate 215 to seal the space on the lower side of the lifting sealing plate 215. A cleaning groove matching the rotating cleaning installation plate 232 is carved inside the dry-type transformer body 1, which facilitates the accommodation of the rotating cleaning installation plate 232, provides sufficient space for cleaning the lifting filter screen 211, and provides corresponding space for the rotation of the rotating cleaning installation plate 232.

[0041] like Figures 1 to 2 As shown, the synchronization assembly 22 includes: a synchronization power chamber 221, a synchronization power shaft 222, a pair of synchronization power drive bevel gears 223, and a synchronization power motor 224. The synchronization power chamber 221 is fixedly installed on one side of the dry-type transformer body 1. The synchronization power chamber 221 can accommodate the synchronization power shaft 222, reducing damage to the synchronization power shaft 222 and extending its service life. The synchronization power shaft 222 is rotatably installed within the synchronization power chamber 221. The synchronization power shaft 222 can drive the rotation of the pair of synchronization power drive bevel gears 223, providing the corresponding power for the rotation of the pair of synchronization power drive bevel gears 223 and providing the corresponding position for the installation of the synchronization power drive bevel gears 223. The pair of synchronization power drive bevel gears 223 are fixedly installed on the synchronization power shaft 222. The synchronization power drive bevel gears 223 can drive the rotation of the lifting driven bevel gear 214, providing the corresponding power for the lifting of the lifting filter screen 211. The synchronous power motor 224 is fixedly installed at one end of the synchronous power shaft 222 and is also fixedly installed with the synchronous power housing 221. The synchronous power motor 224 can provide the corresponding power for the rotation of the synchronous power shaft 222. At the same time, the fixed installation with the synchronous power housing 221 reduces the probability of disengagement, improves the balance of the synchronous power shaft 222, further enhances the stability of the synchronous power shaft 222, and improves the precision between the synchronous power driving bevel gear 223 and the lifting driven bevel gear 214.

[0042] like Figures 1 to 6As shown, the synchronous drive shaft 222 is installed through the synchronous drive housing 221, which improves the balance of the synchronous drive shaft 222 and reduces the probability of the synchronous drive shaft 222 detaching. At the same time, the installation through the synchronous drive housing 221 allows the synchronous drive motor 224 to be fixedly installed with the synchronous drive shaft 222, providing convenience for the installation of the synchronous drive motor 224. A pair of synchronous drive bearings 225 are installed between the synchronous drive shaft 222 and the synchronous drive housing 221. The synchronous drive bearings 225 reduce the friction between the synchronous drive shaft 222 and the synchronous drive housing 221. The friction between the synchronous power chambers 221 improves the stability of the synchronous power shaft 222, reduces the damage caused by friction between the synchronous power chambers 221 and the synchronous power shaft 222, and extends the service life of the synchronous power chambers 221 and the synchronous power shaft 222. The synchronous power drive bevel gear 223 meshes with the lifting driven bevel gear 214, and the synchronous power drive bevel gear 223 can drive the rotation of the lifting driven bevel gear 214, so that the lifting threaded rod 213 can rotate synchronously, providing the corresponding power for the lifting of the lifting filter screen 211.

[0043] like Figures 1 to 7 As shown, the positioning power assembly 3 includes: a positioning power motor 31, a pair of positioning drive pulleys 32, and a positioning timing belt 33. The positioning power motor 31 is fixedly installed on one side of the dry-type transformer body 1 and extends through the body. The positioning power motor 31 provides power for the rotation of the positioning drive pulleys 32, while reducing the likelihood of tilting, allowing the positioning drive pulleys 32 to more stably drive the rotation of the positioning timing belt 33. The pair of positioning drive pulleys 32 are fixedly installed on the positioning power motor 31 and can drive the rotation of the rotating cleaning driven pulley 234 via the positioning timing belt 33, providing power for the rotation of the rotating cleaning driven pulley 234. The positioning timing belt 33 is installed between the positioning active pulley 32 and the rotating cleaning driven pulley 234. The positioning timing belt 33 can play a transmission role, providing corresponding assistance for the positioning active pulley 32 to drive the rotation of the rotating cleaning driven pulley 234, so that a pair of rotating cleaning brushes 233 can clean the lifting filter screen 211, thereby improving the cleanliness of the lifting filter screen 211.

[0044] like Figures 1 to 7As shown, the flushing assembly 41 includes: a pair of flushing support chambers 411, a flushing connecting hose 412, and a flushing temporary storage chamber 413. The pair of flushing support chambers 411 are fixedly installed inside the dry-type transformer body 1. The flushing support chambers 411 can temporarily contain the cleaning fluid and provide corresponding outlets for the discharge of the cleaning fluid, allowing the cleaning fluid to flush the lifting filter screen 211. The flushing connecting hose 412 is fixedly installed on the lower side of the flushing support chambers 411 and passes through both the flushing support chambers 411 and the dry-type transformer body 1. The flushing connecting hose 412 connects the flushing support chambers 411 and the flushing temporary storage chamber 413, allowing the cleaning fluid in the flushing temporary storage chamber 413 to enter the flushing connecting hose 412, and enabling the flushing support chambers 411 to be replenished with cleaning fluid at any time. The flushing storage chamber 413 is fixedly installed on one side of the dry-type transformer body 1 and is connected to the flushing connection hose 412. The flushing storage chamber 413 can temporarily contain the cleaning fluid, and the cleaning fluid in the flushing support chamber 411 can be replenished at any time through the flushing connection hose 412.

[0045] like Figures 1 to 3 As shown, the injection assembly 42 includes: an injection receiving chamber 421, an injection filter chamber 422, an injection connecting water pump 423, a pair of injection support bars 424, and a pair of injection connecting pipes 425. The injection receiving chamber 421 is fixedly installed on the lower side of the dry-type transformer body 1. The injection receiving chamber 421 can temporarily contain the cleaning fluid and facilitates the installation of the injection filter chamber 422, providing a suitable position for its installation, reducing the probability of the injection filter chamber 422 detaching, and improving the stability of the injection filter chamber 422. The injection filter chamber 422 is slidably installed within the injection receiving chamber 421. The injection filter chamber 422 can filter the cleaning fluid to a certain extent, reducing the probability of dust re-entering the flushing assembly 41, making the cleaning fluid used in the flushing assembly 41 cleaner. An injection pump 423 is fixedly installed inside the injection receiving chamber 421 and extends through both the injection receiving chamber 421 and the flushing storage chamber 413. The injection pump 423 draws cleaning fluid from the injection receiving chamber 421 and injects it into the flushing storage chamber 413, ensuring that the cleaning fluid in the flushing storage chamber 413 is replenished as needed. A pair of injection support bars 424 are located on the lower side of the injection receiving chamber 421 and are fixedly installed thereto. The injection support bars 424 support the injection filter chamber 422, reducing the likelihood of tilting and improving its stability, making the extraction and removal of the injection filter chamber 422 smoother. A pair of injection connecting pipes 425 are fixedly installed on the lower side of the dry-type transformer body 1 and extend through it, connecting the cleaning tank and the injection receiving chamber 421. This allows wastewater from the cleaning tank to enter the injection receiving chamber 421, ensuring that the cleaning fluid in the injection receiving chamber 421 is replenished accordingly.

[0046] like Figures 1 to 6 As shown, the dehumidification assembly 43 includes: a dehumidification fixing rod 431, a dehumidification rotating sponge 432, and a dehumidification rotating bearing 433. The dehumidification fixing rod 431 is fixedly installed inside the dry-type transformer body 1. The dehumidification fixing rod 431 supports the dehumidification rotating sponge 432, providing a corresponding axis for the rotation of the dehumidification rotating sponge 432, thus increasing the probability and degree of contact between the dehumidification rotating sponge 432 and the lifting filter screen 211. The dehumidification rotating sponge 432 is sleeved and installed on the outside of the dehumidification fixing rod 431. The dehumidification rotating sponge 432 can absorb water droplets on the surface of the lifting filter screen 211, reducing the moisture on the surface of the lifting filter screen 211, reducing the probability of moisture entering the dry-type transformer body 1, and improving the safety of the dry-type transformer body 1 in use. The dehumidifying rotating bearing 433 is installed between the dehumidifying fixed rod 431 and the dehumidifying rotating sponge 432, which reduces the friction between the dehumidifying fixed rod 431 and the dehumidifying rotating sponge 432, improves the smoothness of the rotation of the dehumidifying rotating sponge 432, makes it easier for the dehumidifying rotating sponge 432 to be driven to rotate by the lifting filter screen 211, and makes it easier for the water in the dehumidifying rotating sponge 432 to be squeezed out.

[0047] like Figures 1 to 8 As shown, the enhancement component 44 includes: a dehumidifying squeeze roller 441, a dehumidifying squeeze base 442, and several pairs of dehumidifying telescopic rods 443. The dehumidifying squeeze roller 441 is located below the dehumidifying rotating sponge 432. The dehumidifying squeeze roller 441 can squeeze the dehumidifying rotating sponge 432, squeezing out the cleaning liquid inside, making the dehumidifying rotating sponge 432 drier when it comes into contact with the lifting filter screen 211, and absorbing more moisture. The dehumidifying squeeze base 442 is located below the dehumidifying squeeze roller 441 and extends through the dehumidifying squeeze roller 441. The dehumidifying squeeze base 442 can support the dehumidifying squeeze roller 441, reducing the likelihood of the dehumidifying squeeze roller 441 tilting. Several pairs of dehumidifying telescopic rods 443 are installed between the dehumidifying squeezing seat 442 and the rinsing support chamber 411. They can support the dehumidifying squeezing seat 442, allowing it to better squeeze the dehumidifying rotating sponge 432 and improve the drying degree of the dehumidifying rotating sponge 432.
