Abstract
Description
Technical Field
[0001] The utility model relates to the field of dry-type transformers, in particular to a dust-proof and noise-reduction structure of a dry-type transformer. Background Art
[0002] During operation, dry-type transformers are susceptible to inhaling dust and impurities from the air due to the complexity of their surrounding environment. If these dust and impurities enter the transformer, they can adhere to components such as insulation materials and coils, leading to reduced insulation performance and poor heat dissipation, which in turn affects the normal operation and service life of the transformer.
[0003] Dry-type transformers generate a certain amount of noise during operation, primarily due to vibrations in the core and windings. When the transformer is subjected to alternating current, electromagnetic forces act on the core and windings, generating vibration and noise. Furthermore, auxiliary equipment such as the transformer's fan and oil pump also generate noise. This noise not only disrupts the surrounding environment but can also adversely affect the health of workers.
[0004] Dry-type transformers generate a lot of heat during operation. If the heat cannot be dissipated in time, the transformer temperature will rise, which will affect its performance and life. Therefore, how to effectively cool the transformer is a very important issue. Utility Model Content
[0005] The purpose of the utility model is to provide a dust-proof and noise-reduction structure for a dry-type transformer, which can achieve the functions of dust-proof and noise-reduction while also providing cooling. In addition, multiple settings can be replaced, which increases the service life of the structure and increases the recyclability of the structure.
[0006] To achieve the above-mentioned objectives, the utility model provides a dust-proof and noise-reduction structure for a dry-type transformer, comprising a base, a noise reduction box being arranged above the base, a purification chamber being arranged on the base, cooling chambers being arranged on both sides of the purification chamber, a ventilation pipe being arranged on the base and passing through the cooling chamber and connecting to the purification chamber, and a suction fan being connected to one end of the ventilation pipe.
[0007] Preferably, a purification liquid is provided in the purification chamber, and a condensate is provided in the cooling chamber.
[0008] Preferably, slopes are provided above the base at both ends, with a distance between the slopes; a drainage pipe is provided on the side wall of the base, and the drainage pipe is located at the lower end of the slope.
[0009] Preferably, the other end of the ventilation pipe is located at the bottom end of the purification chamber.
[0010] Preferably, one end of the ventilation pipe connected to the suction fan is provided with a primary filter and a secondary filter in sequence.
[0011] Preferably, a through hole is provided at the bottom of the noise reduction box, and the through hole is located above the slopes.
[0012] Preferably, the inner layer of the noise reduction box is provided with sound-absorbing cotton.
[0013] Preferably, the noise reduction box is provided with a first fixing unit and a second fixing unit at the upper and lower ends. The first fixing unit is a symmetrically arranged L-shaped plate, and the second fixing unit has one side set as a straight plate and the side perpendicular to the straight plate set as an inclined plate, and the inclined plate is connected to the straight plate.
[0014] Preferably, a breathable plate is provided on the top of the noise reduction box.
[0015] Therefore, the present invention adopts the above-mentioned dust-proof and noise-reduction structure of a dry-type transformer, and the technical effects are as follows:
[0016] Dust-proof design: The purification fluid, primary and secondary filters, and the purification chamber effectively remove dust and impurities from the air, preventing them from entering the transformer. A removable ventilation duct facilitates maintenance and filter replacement. Furthermore, the sloped design and drain pipe collect and discharge any airborne purification fluid, maintaining cleanliness and normal operation.
[0017] Noise reduction design: The sound-absorbing cotton lining the noise reduction box effectively absorbs the noise generated by the transformer during operation. In addition, the breathable panel on the top ensures air circulation while reducing direct noise transmission.
[0018] Cooling design: The condensate in the cooling chamber and the structural design of the purification chamber make the air entering the purification chamber be cooled first, thus reducing the temperature around the transformer. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solution of the present utility model is further described below through the accompanying drawings and embodiments.
[0025] Unless otherwise defined, technical or scientific terms used in the present invention should have the common meanings understood by persons having ordinary skills in the field to which the present invention belongs.
[0026] Example 1
[0027] The utility model provides a dust-proof and noise-reduction structure for a dry-type transformer, comprising a base 1, a noise reduction box 2 is arranged above the base 1, a purification chamber 3 is arranged on the base 1, a purification liquid is arranged in the purification chamber 3, cooling chambers 4 are respectively arranged on both sides of the purification chamber 3, and condensate is arranged in the cooling chamber 4.
[0028] A ventilation pipe 5 is provided on the base 1 and passes through the cooling chamber 4 and is connected to the purification chamber 3. One end of the ventilation pipe 5 is connected to a suction fan 6.
[0029] Air is drawn into the ventilation duct 5 by the suction fan 6. The air in the ventilation duct 5 passes through the cooling chamber 4, where its temperature drops. The air then enters the purification liquid, where impurities are filtered out. Since the other end of the ventilation duct 5 is located at the bottom of the purification chamber 3, the air is fully purified. Furthermore, since the purification chamber 3 is enclosed within the cooling chamber 4, the air is cooled again as it passes through the purification chamber 3.
[0030] The end of the ventilation duct 5 connected to the suction blower 6 is provided with a primary filter 10 and a secondary filter 11. The primary and secondary filters 10 and 11 filter the air and remove impurities, reducing the amount of impurities that enter the purified liquid and reducing the need for purified liquid replacement. The ventilation duct 5 is removable, allowing the coolant and purified liquid to be replaced through the holes in the duct.
[0031] A single-section ventilation pipe 5 can be provided at the position where the primary filter screen 10 and the secondary filter screen 11 are provided, so as to facilitate replacement of the primary filter screen 10 and the secondary filter screen 11 .
[0032] Slopes 7 are provided above the base 1 at both ends to collect the purified liquid brought out with the air. A drain pipe 9 is provided on the side wall of the base 1. The drain pipe 9 is located at the lower end of the slope 7, and the collected purified liquid is discharged through the drain pipe 9.
[0033] There is a distance between the slopes 7 , and a through hole 12 is provided at the bottom of the noise reduction box 2 . The through hole 12 is located above the slopes 7 , and air is fed into the noise reduction box 2 .
[0034] The noise reduction box 2 is provided with a first fixing unit 14 and a second fixing unit 15 at its upper and lower ends. The first fixing unit 14 is a symmetrical L-shaped plate, while the second fixing unit 15 is a straight plate on one side and an inclined plate on the other side perpendicular to the straight plate. The inclined plates are connected to each other. During installation, the dry-type transformer 8 can be installed in the noise reduction box 2 first, and then the inclined plates are connected to the straight plates. The connection between the inclined plates and the straight plates can be various methods, such as welding, bolting, or snap fastening.
[0035] A breathable plate 16 is provided on the top of the noise reduction box 2, and the breathable plate 16 connects the noise reduction box 2 with the atmosphere to achieve air circulation.
[0036] The inner layer of the noise reduction box 2 is provided with sound-absorbing cotton 13 to reduce the noise of the dry-type transformer 8. However, since the sound-absorbing cotton 13 itself has a heat-insulating effect, the dry-type transformer 8 generates a large amount of heat during operation. Therefore, in addition to preventing dust and reducing noise, it is also necessary to reduce the temperature. The cooling chamber 4 is provided, and the purification chamber 3 is surrounded by the cooling chamber 4 to further cool the air, thereby achieving cooling of the dry-type transformer 8.
[0037] Therefore, the utility model adopts the above-mentioned dust-proof and noise-reduction structure of the dry-type transformer, which can achieve the function of dust-proof and noise-reduction while also having the function of cooling. In addition, multiple settings can be replaced, which improves the service life of the structure and increases the recyclability of the structure.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
