Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an air-cooled transformer with an air filtering function. Background Art

[0002] Dry-type transformer is an important power equipment, which plays a vital role in the power system. Unlike the traditional oil-immersed transformer, the core and winding of the dry-type transformer do not use insulating oil for cooling and insulation, but use air as the cooling medium. This feature makes the dry-type transformer have significant advantages in safety, environmental protection, maintenance and other aspects.

[0003] Air-cooled transformers rely on air convection for cooling, so they need to be equipped with air inlets, air ducts, and air outlets. Because there are impurities such as dust in the air, for transformers placed outdoors, there are insects outside, and insects can enter the air duct through the air inlet. Dust nets are generally used to prevent dust and insects from entering the transformer, but the dust nets need to be replaced frequently, and the dust nets will increase the resistance of air entering the air duct, and the dust nets have poor blocking ability for fine dust. Even if dust nets are installed, fine dust can still enter the transformer, and because there are only small holes on the dust net, it is necessary to increase the power of the fan to be able to suck the outside gas into the air duct, which increases energy consumption and cannot completely block the entry of dust. Summary of the invention

[0004] The utility model aims to solve the problems existing in the background technology and proposes an air-cooled transformer with an air filtering function which prevents dust from entering the box.

DETAILED DESCRIPTION

[0031] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] Example

[0033] like Figure 1-7As shown, the utility model provides an air-cooled transformer with air filtering function, including a box body 1, a transformer 2 fixedly installed in the box body 1, a plurality of air inlet holes 3 are provided on one side of the box body 1, and a plurality of air outlet holes 4 are provided on the other side of the box body 1. An installation box 5 is installed in the box body 1 and located on one side of the air inlet holes 3, a plurality of first fans 501 are installed in the installation box 5, a water tank 503 is located on the box body 1 and below the first fans 501, a filtered liquid 504 is provided in the water tank 503, and an air inlet pipe 502 is installed on the installation box 5, and the air inlet pipe 502 extends to the bottom of the water tank 503. When heat dissipation is performed, the first fan 501 is started to suck outside air into the air inlet pipe 502. The gas will enter the bottom of the water tank 503 through the air inlet pipe 502 and come into contact with the filtered liquid 504. By bringing the gas into contact with the filtered liquid 504, impurities in the gas will be filtered by the filtered liquid 504. The dust in the gas will sink after coming into contact with the filtered liquid 504, and the gas will float upward.

[0034] like Figure 7 As shown, the stirring mechanism is installed in the water tank 503, and the stirring mechanism destroys the bubbles formed by the gas entering the water tank 503. The stirring mechanism includes a motor 601 fixedly installed on the installation box 5, and two stirring blades 6 rotatably installed in the water tank 503, and a linkage belt 602 is installed on the two stirring blades 6. The starting motor 601 drives the two stirring blades 6 to rotate through the linkage belt 602, thereby crushing the bubbles formed in the filtrate 504, thereby preventing the impurities contained in the bubbles from being transferred to the box body 1 through the bubbles.

[0035] like Figure 7 As shown, the dehumidification mechanism is installed on both sides of the box body 1, and the dehumidification mechanism dehumidifies the gas passing through the water tank 503. The dehumidification mechanism includes a dehumidification box 7 fixedly installed in the box body 1 and located on both sides of the water tank 503, a second fan 701 fixedly installed on the dehumidification box 7, a plurality of moisture-absorbing cottons 703 fixedly installed in the dehumidification box 7, and an air pipe 702 fixedly installed on the dehumidification box 7, and the air pipe 702 is connected with the water tank 503 and the dehumidification box 7. The second fan 701 is started to extract the gas passing through the filtrate 504, and the gas is contacted with the moisture-absorbing cotton 703 through the dehumidification box 7, and the moisture-absorbing cotton 703 absorbs the moisture in the gas, thereby preventing the humidity in the box body 1 from being too high.

[0036] like Figure 7As shown, a compression mechanism is installed in the box body 1, and the compression mechanism discharges the moisture in the moisture-absorbing cotton 703. The compression mechanism includes a first electric telescopic rod 8 fixedly installed on the box body 1 and located above the dehumidification box 7, a pressing plate 801 slidably installed in the dehumidification box 7, and a water pipe 802 fixedly installed at the bottom of the dehumidification box 7, one end of the water pipe 802 is connected to the dehumidification box 7 and the other end is connected to the water tank 503. When the moisture in the moisture-absorbing cotton 703 is too high, the first electric telescopic rod 8 is started to drive the pressing plate 801 to compress the moisture-absorbing cotton 703, so that the moisture in the moisture-absorbing cotton 703 can be discharged, and the discharged moisture flows into the water tank 503 again through the water pipe 802.

[0037] like Figure 5 and Figure 8-9 As shown, the closing mechanism is installed in the box body 1 and is located on one side of the air outlet 4, and the closing mechanism controls the open and blocked state of the air outlet 4. The closing mechanism includes a mounting plate 9 fixedly installed on the box body 1 and located on one side of the air outlet 4, a second electric telescopic rod 901 fixedly installed on the mounting plate 9, a plurality of baffles 902 slidably installed on the box body 1, and a plurality of plugs 904 fixedly installed on the baffles 902. The telescopic shaft of the second electric telescopic rod 901 is fixedly connected to the baffles 902, and a connecting rod 903 is fixedly installed between two adjacent baffles 902. When heat dissipation occurs, the second electric telescopic rod 901 is started to drive the baffle 902 to move toward the inside of the box 1, thereby driving the plug 904 to move to the outside of the air outlet 4, so that the gas entering the box 1 can be discharged, and air is blown outward at this time, and external dust cannot enter the inside of the box 1 through the air outlet 4. When heat dissipation is not performed, the second electric telescopic rod 901 drives the plug 904 to move, so that the plug 904 blocks the air outlet 4.

[0038] Working principle: Start the first fan 501 to suck outside air into the air inlet pipe 502. The gas will enter the bottom of the water tank 503 through the air inlet pipe 502 and contact the filtered liquid 504. The dust in the gas will sink after contacting the filtered liquid 504, and the gas will float upward. The motor 601 is started to drive the two stirring blades 6 to rotate through the linkage belt 602, so as to crush the bubbles formed in the filtered liquid 504, thereby preventing the impurities contained in the bubbles from being transferred to the box body 1 through the bubbles. Start the second fan 701 to extract the gas passing through the filtered liquid 504, and contact the moisture-absorbing cotton 703 through the dehumidification box 7. The moisture-absorbing cotton 703 absorbs the moisture in the gas, thereby preventing the humidity in the box body 1 from being too high. Start the second electric telescopic rod 901 to drive the baffle 902 to move toward the inside of the box 1, thereby driving the plug 904 to move to the outside of the air outlet 4, so that the gas entering the box 1 can be discharged, and air is blown outward at this time, and external dust cannot enter the inside of the box 1 through the air outlet 4. When heat dissipation is not performed, the second electric telescopic rod 901 drives the plug 904 to move, so that the plug 904 blocks the air outlet 4.
