[0002] A transformer is a static electrical device that converts an AC voltage of a certain value into another or several voltages of different values ​​with the same frequency through electromagnetic coupling. In long-distance power transmission, transformers play an important role. On the one hand, the transformer increases the voltage and sends the electricity to the power consumption area. On the other hand, the transformer reduces the voltage to various levels of usage voltage to meet the user's electricity demand. Noise is generated during the operation of the transformer, and the noise of the transformer not only pollutes the environment, but also endangers human health. The noise of the transformer is mostly caused by the contact between the transformer and the mounting plate when it vibrates. In order to reduce the spread of noise, the cabinet is generally set to a sealed structure, but this method will have a greater impact on the heat dissipation effect of the cabinet, affecting the heat dissipation of the transformer, and affecting the normal operation of the transformer when overheated.

The serrated noise reduction pad 31 is used to buffer the force generated by the transformer components, so that when the transformer components vibrate, the vibration between the elastic mounting plate 4 and the transformer mounting frame 3 after being subjected to the force is buffered by the serrated noise reduction pad 31, thereby reducing noise again. A plurality of strip-shaped sound-absorbing cottons 311 are arranged between the serrated noise reduction pad 31 and the elastic mounting plate 4. The strip-shaped sound-absorbing cottons 311 are arranged to fill the space between the serrated noise reduction pad 31 and the elastic mounting plate 4, thereby reducing the deformation range of the serrated noise reduction pad 31 after receiving the force, thereby increasing the buffering effect of the serrated noise reduction pad 31 and improving the noise reduction of the serrated noise reduction pad 31.

Since the transformer mounting frame 3 and the support frame 32 are made of relatively hard materials, the noise is relatively large during vibration. The noise generated by the vibration between the transformer mounting frame 3 and the support frame 32 is reduced through the buffering of the rubber gasket 33. The elastic mounting plate 4 is composed of a plurality of connecting plates 41 and a plurality of rubber connecting strips 42, wherein the rubber connecting strips 42 are elastic structures. Under the effect, the elastic mounting plate 4 has a certain elastic force, and is connected to the raised end of the serrated noise reduction pad 31 through the rubber connecting strip 42. When the transformer vibrates during operation, several connecting plates 41 vibrate with the same amplitude after being subjected to the force. However, since the connecting plates 41 are not connected to each other and are replaced by the rubber connecting strip 42, the noise generated by the vibration between some transformer components and the elastic mounting plate 4 is reduced, so that the present invention can reduce the vibration between the transformer and the installation position in the cabinet cavity during operation. By setting the serrated noise reduction pad 31, the strip sound-absorbing cotton 311, the rubber gasket 33 and the rubber connecting strip 42 and other soft connections, the noise generated by the collision between the hard plates during vibration is reduced, and the collision between the transformer components and the mounting plate can be reduced.This reduces the noise generated by the transformer components when they are working, and can maintain the cabinet sealing and noise reduction while maintaining the heat dissipation effect of the working components in the cabinet cavity, thereby improving the protection effect of the working components.

[0019] One end of the sound-absorbing cotton partition 2 is detachably connected to a movable sealing plate 21, the movable sealing plate 21 is snap-connected to the opening of the connecting cavity 12, and the sound-absorbing cotton partition 2 is slidably connected to the inner walls on both sides of the connecting cavity 12; by setting the movable sealing plate 21, the sound-absorbing cotton partition 2 is connected, which facilitates the disassembly and assembly of the sound-absorbing cotton partition 2 and its replacement. After opening the movable sealing plate 21, the heat dissipation effect of the area between the partitions 11 can be increased.

[0020] A plurality of connecting plates 41 and a plurality of rubber connecting strips 42 are arranged alternately, and the adjacent connecting plates 41 are movably connected to the rubber connecting strips 42. A plurality of heat dissipation holes 411 are provided on the top of the connecting plates 41. By providing a plurality of heat dissipation holes 411 on the top of the connecting plates 41, the air flow at the bottom of the transformer is increased, thereby increasing the heat dissipation effect on the bottom of the transformer.

[0021] The rubber gasket 33 is clamped and set at the top of the support frame 32, and the two ends of the transformer mounting frame 3 are fixed to the support frame 32 through mounting parts; so that the transformer mounting frame 3 and the support frame 32 cannot be in direct contact, and the noise generated by the vibration between the transformer mounting frame 3 and the support frame 32 is reduced through the buffering of the rubber gasket 33.

[0022] A cabinet door is hinged on the front side of the cabinet body 1, and the cabinet door is arranged between two partitions 11, and the partitions 11 are set as a hollow structure; by arranging the cabinet door between the partitions 11, it is convenient to inspect and maintain the interior of the cabinet body 1, and by setting the partitions 11 as a hollow structure, it is convenient for the area between the partitions 11 to dissipate heat to the outside.

[0023] The working principle and use process of the utility model are as follows: when in use, each transformer component is installed on the top of the elastic mounting plate 4. During the operation of the transformer, a sound-absorbing cotton partition layer 2 is arranged in the inner cavity of the connecting cavity 12 to prevent the noise generated by the operation of the transformer in the inner cavity of the cabinet 1 from being transmitted to the outside of the cabinet 1, thereby reducing the noise of the cabinet 1. The serrated noise reduction pad 31 is used to reduce the pressure of each component installed on the top of the elastic mounting plate 4 on the transformer mounting frame 3. The serrated noise reduction pad 31 is used to buffer the force generated by the transformer components. When the transformer components vibrate, the vibration between the elastic mounting plate 4 and the transformer mounting frame 3 after being subjected to the force is buffered by the serrated noise reduction pad 31, thereby reducing the noise again. A plurality of strip-shaped sound-absorbing cottons 311 are arranged between the serrated noise reduction pad 31 and the elastic mounting plate 4. The strip-shaped sound-absorbing cottons 311 are arranged to fill the space between the serrated noise reduction pad 31 and the elastic mounting plate 4 to reduce the noise generated by the serrated noise reduction pad. The range of deformation of 31 after receiving the force, thereby increasing the buffering effect of the serrated noise reduction pad 31, improving the noise reduction effect of the serrated noise reduction pad 31, and arranging a rubber gasket 33 at the top of the support frame 32, so that the transformer mounting frame 3 and the support frame 32 cannot be in direct contact. Since the transformer mounting frame 3 and the support frame 32 are both made of relatively hard materials, the noise is relatively large during vibration. The buffering of the rubber gasket 33 reduces the noise generated by the vibration between the transformer mounting frame 3 and the support frame 32. Under the connection effect of the rubber connecting strip 42, the elastic mounting plate 4 has a certain elastic force, and is connected to the raised end of the serrated noise reduction pad 31 through the rubber connecting strip 42. When the transformer vibrates during operation, several connecting plates 41 vibrate with the same amplitude after receiving the force. However, since the connecting plates 41 are not connected to each other and are replaced by the rubber connecting strip 42, the noise generated by the vibration between some transformer components and the elastic mounting plate 4 is reduced.
