Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a noise reduction transformer. Background Art

[0002] Transformers are crucial components of power systems, playing a crucial role in changing voltage during the transmission and distribution of electrical energy. However, transformers generate significant noise during operation, which not only pollutes the surrounding environment and impacts people's lives and work, but also can damage operators' hearing if exposed to prolonged high-noise environments. Traditional transformer noise reduction measures often have limited effectiveness and fail to meet increasingly stringent environmental and work environment requirements.

[0003] Most of the existing transformer noise reduction methods are to install corresponding sound insulation covers for the transformers. Although this can play a role in noise reduction, most of these sound insulation covers wrap the surface of the transformer, which also wraps the heat sink inside the sound insulation cover. The heat dissipation function of the heat sink is limited, and the temperature continues to rise, which can easily cause damage to the transformer. However, if the surface of the transformer is not wrapped, the noise reduction effect cannot be optimized. Summary of the Invention

However, if the surface of the transformer is not wrapped, the noise reduction effect cannot be optimized.

[0005] To achieve the above object, a noise reduction transformer is provided, comprising a body, a support block for supporting the body being fixedly connected below the body, a base being fixedly connected below the support block, and heat sinks for dissipating heat from the body being fixedly connected to all four sides of the body;

The first soundproof cover slides through the cooling plate to control the contact and separation with the body. The first soundproof cover can reduce noise on the two longer surfaces of the body;

[0008] The second sound insulation cover is arranged on the sides of the two shorter surfaces of the body and wraps the heat sinks on the corresponding sides of the body. The inner side of the second sound insulation cover is also slidably connected with a cooling plate. The side of the cooling plate away from the second sound insulation cover is fixedly connected to the body. The second sound insulation cover slides through the cooling plate to control the fit and separation with the body. The second sound insulation cover can reduce the noise of the two shorter surfaces of the body.

[0009] As a further improvement of the present technical solution, a connecting rod is fixedly connected to the surface of the first sound insulation cover, and an end of the connecting rod away from the first sound insulation cover is fixedly connected to the first partition.

[0012] As a further improvement of the present technical solution, a second partition is fixedly connected to the surface of the second sound insulation cover, an inclined plate is fixedly connected to the inner side of the second partition, a sliding groove is provided on the surface of the inclined plate corresponding to the top rod, the inner cavity of the sliding groove is slidably connected to the beveled surface of the top rod, and a plurality of groups of circular holes are provided on the surface of the inclined plate.

[0013] As a further improvement of the present technical solution, the inner cavities of the first sound insulation cover and the second sound insulation cover are both provided with the same device, the inner cavity of the first sound insulation cover is fixedly connected to the first sound absorbing board, the inner cavity of the first sound insulation cover and one side of the first sound absorbing board is fixedly connected to the metal sound insulation board, the inner cavity of the first sound insulation cover and one side of the metal sound insulation board is fixedly connected to the second sound absorbing board, and the inner cavity of the first sound insulation cover and one side of the second sound absorbing board is fixedly connected to the sound absorbing cotton board.

[0015] As a further improvement of the present technical solution, shock-absorbing pads are fixedly connected to the top of the base and on both sides of the support block, and a spring is fixedly connected between the top of the shock-absorbing pad and the bottom of the body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this noise reduction transformer, the hydraulic cylinder drives the telescopic end to extend and drive the first partition to move, and the movement of the first partition drives the movement of the first sound insulation cover. After the first sound insulation cover moves, the cooling plate leaks out. At this time, the natural wind from the outside can blow to the heat sinks on the two longer sides of the body through the ventilation holes on the cooling plate, so that the heat generated by the transformer can be eliminated. At the same time, the hydraulic cylinder drives the telescopic end to extend and drive the circular ring to move, and the movement of the circular ring drives the vertical rod to move, and the movement of the vertical rod drives the top rod to move the top of the inclined plate, and the movement of the inclined plate drives the second sound insulation cover to move, so that the cooling plate inside the second sound insulation cover also leaks out. At this time, the natural wind from the outside can blow to the heat sinks on the two shorter sides of the body through the ventilation holes on the cooling plate. The heat sinks on the four sides are in contact with the natural wind at the same time and cool down quickly. The heat dissipation function of the heat sink will not be limited, and the temperature will continue to rise, which will easily cause damage to the transformer, thereby improving the service life of the transformer.

[0018] 2. In this noise-reducing transformer, the first sound-absorbing panel, the metal sound insulation panel, the second sound-absorbing panel and the sound-absorbing cotton panel work together to significantly reduce the noise generated during the operation of the transformer, effectively improve the quality of the surrounding environment, reduce health hazards to operators, and at the same time ensure the normal operation and maintenance convenience of the transformer.

[0019] 3. In this noise reduction transformer, springs are evenly distributed at the bottom of the body, and shock-absorbing pads are set under the springs to reduce vibration transmission during transformer operation, thereby reducing noise generated by vibration.

[0033] See also Figures 1-8 As shown, the present embodiment aims to provide a noise reduction transformer, comprising a body 1, a support block 2 for supporting the body 1 being fixedly connected below the body 1, a base 3 being fixedly connected below the support block 2, and heat sinks 4 for dissipating heat from the body 1 being fixedly connected to all four sides of the body 1;

[0034] Also includes:

[0035] A first soundproof cover 5 is provided on the sides of the two longer surfaces of the body 1 and wraps the heat sink 4 on the corresponding sides of the body 1. A cooling plate 7 is slidably connected to the inside of the first soundproof cover 5. The cooling plate 7 is fixedly connected to the body 1 on the side away from the first soundproof cover 5. The first soundproof cover 5 slides through the cooling plate 7 to control the fit and separation with the body 1. The first soundproof cover 5 can reduce noise on the two longer surfaces of the body 1;

[0036] The second sound insulation cover 6 is arranged on the side of the two shorter surfaces of the body 1 and wraps the heat sink 4 on the corresponding side of the body 1. The inner side of the second sound insulation cover 6 is also slidably connected with a cooling plate 7. The cooling plate 7 is fixedly connected to the body 1 on the side away from the second sound insulation cover 6. The second sound insulation cover 6 slides through the cooling plate 7 to control the fit and separation with the body 1. The second sound insulation cover 6 can reduce the noise of the two shorter surfaces of the body 1.

[0037] A connecting rod 9 is fixedly connected to the surface of the first sound insulation cover 5, and one end of the connecting rod 9 away from the first sound insulation cover 5 is fixedly connected to the first partition 10. A hydraulic cylinder 11 is fixedly connected to the side of the body 1 and on both sides of the first sound insulation cover 5. The telescopic end of the hydraulic cylinder 11 is fixedly connected to a connecting rod 12, and one end of the connecting rod 12 is fixedly connected to the first partition 10. A ring 13 is fixedly connected to the surface of the telescopic end of the hydraulic cylinder 11, and a docking block 14 is fixedly connected to the surface of the ring 13. One end of the docking block 14 is fixedly connected to a vertical rod 15, and a push rod 16 is fixedly connected to the side of the vertical rod 15, and the end of the push rod 16 is an inclined surface.

[0038] A second partition 17 is fixedly connected to the surface of the second soundproof cover 6, and an inclined plate 18 is fixedly connected to the inner side of the second partition 17. A sliding groove 19 is provided on the surface of the inclined plate 18 corresponding to the top rod 16. The inner cavity of the sliding groove 19 is slidably connected to the cut bevel of the top rod 16, and a plurality of groups of circular holes 20 are provided on the surface of the inclined plate 18.

[0039] The slide groove 19 is slidably connected to the push rod 16. When the first sound insulation cover 5 and the second sound insulation cover 6 need to be re-wrapped around the body 1 for noise reduction, the hydraulic cylinder 11 contracts to retract the first sound insulation cover 5, and the push rod 16 moves to drive the second sound insulation cover 6 to fit with the body 1.

[0040] The hydraulic cylinder 11 drives the telescopic end to extend and drive the first partition 10 to move. The movement of the first partition 10 drives the first sound insulation cover 5 to move. After the first sound insulation cover 5 moves, the cooling plate 7 leaks out. At this time, the natural wind from the outside can blow through the ventilation holes 8 on the cooling plate 7 to the heat sinks 4 on the two longer sides of the body 1, which can eliminate the heat generated by the transformer. At the same time, the hydraulic cylinder 11 drives the telescopic end to extend and drive the ring 13 to move. The movement of the ring 13 drives the vertical rod 15 to move. The movement of the vertical rod 15 drives the top rod 16 to move. The movement of the top rod 16 pushes the inclined plate 18 to move. The movement of the inclined plate 18 drives the second sound insulation cover 6 to move, so that the cooling plate 7 inside the second sound insulation cover 6 also leaks out. At this time, the natural wind from the outside can blow through the ventilation holes 8 on the cooling plate 7 to the heat sinks 4 on the two shorter sides of the body 1. The heat sinks 4 on the four sides are exposed to the natural wind at the same time and quickly cool down. The heat dissipation function of the heat sink 4 will not be limited, and the temperature will continue to rise, which will easily cause damage to the transformer, thereby improving the service life of the transformer.

[0041] The inner cavities of the first sound insulation cover 5 and the second sound insulation cover 6 are both provided with the same device. The inner cavity of the first sound insulation cover 5 is fixedly connected to the first sound absorbing panel 21. The inner cavity of the first sound insulation cover 5 and one side of the first sound absorbing panel 21 are fixedly connected to the metal sound insulation panel 22. The inner cavity of the first sound insulation cover 5 and one side of the metal sound insulation panel 22 are fixedly connected to the second sound absorbing panel 23. The inner cavity of the first sound insulation cover 5 and one side of the second sound absorbing panel 23 are fixedly connected to the sound absorbing cotton board 24.

[0042] Through the combined effect of the first sound-absorbing panel 21, the metal sound insulation panel 22, the second sound-absorbing panel 23 and the sound-absorbing cotton panel 24, the noise generated during the operation of the transformer can be significantly reduced, the surrounding environment quality can be effectively improved, the health hazards to operators can be reduced, and the normal operation and maintenance convenience of the transformer can be ensured.

[0043] The inner layer of the first sound absorbing panel 21 and the second sound absorbing panel 23 is a metal panel, and the outer layer is a sound insulation material panel. The sound absorbing cotton panel 24 can be a rock wool panel or other materials with good sound insulation performance. An air layer is formed between the first sound absorbing panel 21 and the metal sound insulation panel 22 to enhance the sound insulation effect.

[0044] A plurality of groups of ventilation holes 8 for cooling are provided on the surface of the cooling plate 7 , and the plurality of groups of ventilation holes 8 are evenly distributed on the surface of the cooling plate 7 .

[0045] Shock-absorbing pads 25 are fixedly connected to the top of the base 3 and on both sides of the support block 2 , and springs 26 are fixedly connected between the top of the shock-absorbing pads 25 and the bottom of the body 1 .

[0046] Working principle: Under normal conditions, the first sound insulation cover 5 and the second sound insulation cover 6 are in close contact with the body 1 to reduce noise to the greatest extent. At this time, the first sound absorbing panel 21, the metal sound insulation panel 22, the second sound absorbing panel 23 and the sound absorbing cotton panel 24 work together to significantly reduce the noise generated during the operation of the transformer and effectively improve the quality of the surrounding environment. The springs 26 are evenly distributed at the bottom of the body 1, and the shock absorbing pads 25 are arranged under the springs 26 to reduce the vibration transmission during the operation of the transformer, thereby reducing the noise generated by the vibration. When the temperature inside the body 1 is too high, the hydraulic cylinder 11 drives the telescopic end to extend and drive the first partition 10 to move. The movement of the first partition 10 drives the first sound insulation cover 5 to move. After the first sound insulation cover 5 moves, the cooling plate 7 is leaked. At this time, the natural wind from the outside can blow to the body 1 for a longer time through the ventilation holes 8 on the cooling plate 7. The heat generated by the transformer can be eliminated by extending the telescopic end 4, and at the same time, the hydraulic cylinder 11 drives the telescopic end to extend to drive the circular ring 13 to move, and the movement of the circular ring 13 drives the vertical rod 15 to move, and the movement of the vertical rod 15 drives the push rod 16 to move, and the movement of the push rod 16 pushes the inclined plate 18 to move, and the movement of the inclined plate 18 drives the second sound insulation cover 6 to move, so that the cooling plate 7 inside the second sound insulation cover 6 also leaks out. At this time, the natural wind from the outside can blow through the ventilation holes 8 on the cooling plate 7 to the heat sinks 4 on the two shorter sides of the body 1. The heat sinks 4 on the four sides are in contact with the natural wind at the same time to quickly cool down. When the first sound insulation cover 5 and the second sound insulation cover 6 need to be re-wrapped around the body 1 to reduce noise, the hydraulic cylinder 11 contracts to retract the first sound insulation cover 5, and drives the second sound insulation cover 6 to fit with the body 1 through the movement of the push rod 16.
