Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer with high-efficiency sound insulation performance. Background Art

[0002] A transformer is a static electrical device used to transform AC voltage and current to transmit AC power. Its main components include primary coil, secondary coil and iron core, and its working principle is based on electromagnetic induction. Transformers can be classified into power transformers, test transformers, instrument transformers and transformers for special purposes according to their uses, such as electric furnace transformers for smelting, welding transformers, rectifier transformers for electrolysis, etc.

[0003] When the transformer is working, it usually generates a lot of noise and dissipates a lot of heat. In order to minimize the impact of the noise generated by the transformer on the surrounding environment, a sound insulation mechanism is usually set in the main box of the transformer. However, in the actual structure of the transformer, the heat dissipation structure usually needs to be connected to the outside world, which is often the main place where the internal working noise of the transformer leaks out.

[0004] For example, after patent search, it was found that the patent number is: CN216212804U, which is a transformer with noise reduction and heat dissipation effect. The motor is started to drive the cooling fan to operate, which can dissipate heat for the device. The hot air in the box is dissipated outward through the air outlet. A filter box is arranged at the air outlet, and a filter net is arranged in the filter box. When the external air interacts with the air inside the box, it can well block impurities and water molecules in the external air from entering the box, so that the transformer has a good heat dissipation and dust prevention effect, which greatly improves the operation efficiency and service life of the transformer. A sound insulation board is fixedly connected to the inner wall of the rear end of the box. The sound insulation board has a double-layer structure, a sound-absorbing layer is arranged at the front end, and the sound-absorbing layer is made of poplar fiber, and a sound insulation layer is arranged at the rear end, and the sound insulation layer is made of polyester fiber. When the transformer body generates noise during operation, the noise is absorbed and reduced by the sound-absorbing layer, and the noise that is not completely absorbed by the sound-absorbing layer will be isolated by the sound insulation layer to prevent the noise from being emitted outside the box, so that the device has good sound insulation and noise reduction performance.

[0005] When the above device is actually used, the moisture in the air is dried by the internal mechanism of the filter box to prevent it from interfering with the operation of the transformer of the above device. However, the filter box connected to the outside world and its internal structure have little blocking effect on the propagation of noise, which inevitably causes the noise generated by the transformer of the above device to propagate outward through the filter box of the above device.

[0006] Therefore, we propose a transformer with high efficiency sound insulation performance to solve the above-mentioned technical problems. Utility Model Content

[0007] In view of this, the present invention aims to solve the above problems by providing a transformer with high-efficiency sound insulation performance.

[0008] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a box body, a box door arranged on one side of the box body and multiple support seats connected to the bottom of the box body, a transformer body is installed in the box body, filter boxes are arranged on both sides of the box body, one side of the filter box is S-shaped and equidistantly distributed and slidably inserted with multiple sound insulation layers, multiple filter layers are arranged between the multiple sound insulation layers, and the filter layers are slidably inserted into the inner side of the filter box, the inner side of the filter layer is filled with desiccant, and the interior of the box body is provided with an air induction mechanism for accelerating air circulation.

[0009] As a preferred solution, the air induction mechanism includes a heat dissipation fan, and a plurality of the heat dissipation fans are symmetrically installed at one end of one group of the filter boxes close to the box body.

[0010] As a preferred solution, an outer layer is provided inside the sound insulation layer, and the outer layer may be made of, but is not limited to, high-density polyethylene.

[0011] As a preferred solution, an inner layer is provided in the sound insulation layer, and the inner layer may be made of, but is not limited to, glass fiber reinforced concrete.

[0012] As a preferred solution, a middle layer is provided in the sound insulation layer, and the middle layer may be made of, but is not limited to, a damping sound insulation composite material.

[0013] As a preferred solution, the desiccant may be but is not limited to silica gel desiccant.

[0014] As a preferred solution, the inner wall of the box body is provided with a sound-absorbing coating, and the sound-absorbing coating may be but is not limited to damping coating.

[0015] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that it mainly has the following advantages:

[0016] When the transformer main body generates noise during operation, the device blocks the noise through the middle part of the S-shaped structure formed by the four groups of sound insulation layers, so that the air entering through the inclined opening of the filter box can be transmitted through the S-shaped channel formed by the four groups of sound insulation layers, and at the same time, the moisture in the air can be absorbed by the filter layer located between two adjacent groups of sound insulation layers, and the multiple groups of filter layers can reduce the noise generated when the transformer main body is working, thereby reducing the situation of its transmission to the outside through the filter box, and at the same time, the sound-absorbing coating can reduce the situation of the noise generated when the filter box is working being transmitted to the outside through the inner wall of the box body, and then the device is started by the air induction mechanism composed of the heat dissipation fan, so that the air outside one group of filter boxes is guided to the other group of filter boxes for discharge, and in this process;

[0017] In addition, through the above-mentioned arrangement, when the device is normally exhausting and cooling, the noise generated by the operation of the transformer body is reduced from being transmitted to the outside through the filter box.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0030] See also Figures 1 to 8The embodiment of the utility model provides a transformer with high-efficiency sound insulation performance, including a box body 1, a box door 2 arranged on one side of the box body 1 and a plurality of support seats 3 connected to the bottom of the box body 1. The box door 2 is connected to the box body 1 through a hinge. By opening or closing the box door 2, the internal space of the box body 1 can be opened or closed. The support seats 3 are specifically provided with four groups, which are fixedly connected to the bottom of the box body 1 by welding. The overall height of the box body 1 can be increased by the support seats 3, and at the same time, the stability of the box body 1 can be improved, and the shaking of the box body 1 can be reduced. The raised overall height will help the device to be affected by the wet ground, thereby increasing the service life of the device. A transformer body 4 is installed in the box body 1, and the transformer body 4 is fixedly installed by bolts Inside the box body 1, filter boxes 5 are arranged on both sides of the box body 1, and two groups of filter boxes 5 are arranged. The two groups of filter boxes 5 are symmetrically distributed and fixed to two opposite outer sides of the box body 1 by welding, and the upper end portion of the filter box 5 has a vent connected to the inside of the box body 1. Through the two groups of filter boxes 5, one group can be used as an air inlet, and the other group is used as an air outlet. Since the two groups of filter boxes 5 are respectively arranged on both sides of the box body 1, when air enters through one group and then passes out through the other group of filter boxes 5, the internal air of the box body 1 can be exchanged with the outside world. At the same time, the lower end of the filter box 5 on the side away from the box body 1 is provided with equidistantly distributed inclined openings, and the inclined openings can make the filter box 5 connected to the outside space. The filter box 5 has a plurality of chutes, and one side of the filter box 5 is equidistantly distributed in an S-shaped manner and is slidably plugged with a plurality of sound insulation layers 6. Specifically, four groups of sound insulation layers 6 are provided, and the sound insulation layers 6 are inserted into the filter box 5 through the chutes provided on the filter box 5, and then fixed to the filter box 5 by bolts. Therefore, the sound insulation layer 6 can be replaced by removing the bolts. A plurality of filter layers 7 are provided between the plurality of sound insulation layers 6, and the filter layers 7 are slidably plugged to On the inner side of the filter box 5, the filter layer 7 is connected to the filter box 5 by bolts. Specifically, there are three groups of filter layers 7, which are slidably plugged into the inner side of the filter box 5 through the slide grooves provided in the filter box 5, and the three groups of filter layers 7 are respectively located between the four groups of sound insulation layers 6. The inner side of the filter layer 7 is filled with a desiccant 11. The desiccant 11 can be replaced by removing the bolts and sliding out the filter layer 7, thereby increasing its service life or improving its use effect. The desiccant 11 can be, but is not limited to, a silica gel desiccant. Through such a structure, the middle part of the S-shaped structure formed by the four groups of sound insulation layers 6 can be blocked. Through this arrangement, the air entering through the inclined opening of the filter box 5 can be transmitted through the S-shaped channel formed by the four groups of sound insulation layers 6.At the same time, the filter layer 7 between two adjacent sound insulation layers 6 can absorb moisture in the air, and the multiple filter layers 7 can reduce the noise generated by the transformer body 4 when it is working, thereby reducing the noise transmitted to the outside through the filter box 5.

[0031] See also Figures 1 to 8 The interior of the box body 1 is provided with an air induction mechanism for accelerating air circulation, and the air induction mechanism includes a heat dissipation fan 12. The heat dissipation fan 12 is provided with a plurality of symmetrically installed at one end of one group of filter boxes 5 close to the box body 1. The heat dissipation fan 12 is fixedly connected to the side wall of the filter box 5 by bolts. When the heat dissipation fan 12 is started, one group of external air can be guided to the inner side of the box body 1, and then discharged through another group of filter boxes 5, thereby completing the air induction process.

[0032] See also Figures 4 to 8 An outer layer 8 is provided inside the sound insulation layer 6. The outer layer 8 can be made of but is not limited to high-density polyethylene. High-density polyethylene has high strength and wear resistance, as well as good sound insulation effect. As the outer protective layer of the sound insulation layer 6, it can effectively protect the internal sound insulation material from the influence of the external environment, such as ultraviolet rays, humidity, chemical corrosion, etc., thereby improving the service life of the sound insulation layer 6.

[0033] See also Figures 4 to 8 An inner layer 10 is arranged in the sound insulation layer 6. The inner layer 10 can be made of but not limited to glass fiber reinforced concrete. Glass fiber reinforced concrete has high strength and durability, can effectively prevent the propagation of sound waves, and provide good sound insulation effect, so that it can remain stable when impacted by sound waves and is not easy to break or deform.

[0034] See also Figures 4 to 8 A middle layer 9 is provided in the sound insulation layer 6. The middle layer 9 may be made of, but not limited to, a damping sound insulation composite material. The damping sound insulation composite material may include a polymer damping material such as rubber, asphalt, etc. and a supporting material such as glass fiber or mineral wool. Therefore, it can effectively absorb and disperse sound waves and reduce the transmission of sound waves. Moreover, the polymer damping material will generate viscous resistance under the action of sound waves, converting sound energy into heat energy, thereby reducing the transmission of sound waves. Supporting materials such as glass fiber or mineral wool provide sufficient rigidity and supporting force, thereby ensuring the stability and durability of the damping material.

[0035] See also Figures 1 to 8 The inner wall of the box body 1 is provided with a sound-absorbing coating, and the sound-absorbing coating may be, but is not limited to, a damping coating. The sound-absorbing coating can reduce the noise generated by the transformer body 4 during operation from being transmitted to the outside through the inner wall of the box body 1.

[0036] In summary, when the transformer main body 4 generates noise during operation, the device blocks the noise through the middle part of the S-shaped structure formed by the four groups of sound insulation layers 6, so that the air entering through the inclined opening of the filter box 5 can be transmitted through the S-shaped channel formed by the four groups of sound insulation layers 6, and at the same time, the moisture in the air can be absorbed by the filter layer 7 located between two adjacent groups of sound insulation layers 6, and the multiple groups of filter layers 7 can reduce the noise generated when the transformer main body 4 is working, thereby reducing the noise transmitted to the outside through the filter box 5, and at the same time, the sound-absorbing coating can reduce the noise generated when the filter box 5 is working. The noise is transmitted to the outside through the inner wall of the box body 1, and then the device is started by the air induction mechanism composed of the heat dissipation fan 12, so that the air outside one group of filter boxes 5 is guided to another group of filter boxes 5 for discharge, and in this process, through the above-mentioned settings, the noise generated by the operation of the transformer main body 4 can be reduced from being transmitted to the outside through the filter box 5 under the condition of normal exhaust and heat dissipation of the device, thereby achieving the high-efficiency sound insulation performance of the device.
