Description

Technical Field

[0001] The invention relates to the technical field of dry-type transformers, and in particular to a novel noise-reducing dry-type transformer. Background Art

[0002] With the continuous development of the power system and the acceleration of urbanization, dry-type transformers, as key equipment in the process of power transmission and distribution, are increasingly used in a wide range of scenarios, covering substations in city centers, commercial complexes, residential communities, and various industrial plants. However, the noise problem generated by traditional dry-type transformers during operation has gradually become prominent, becoming a key factor restricting their further optimization of application.

[0003] In the prior art, when reducing the noise of a dry-type transformer, a soundproof box is generally set up to block the noise and reduce the spread of noise. However, the setting of the soundproof box makes the heat dissipation effect of the transformer poor, and long-term use affects the performance of the transformer or even damages it. Therefore, a new type of noise-reducing dry-type transformer is designed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a new type of noise-reducing dry-type transformer.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A novel dry-type transformer with noise reduction comprises a bottom plate, a protective frame is fixedly connected to the top edge of the bottom plate, two inspection doors are arranged on one side of the protective frame, rubber pads are fixedly connected to the top of the bottom plate near the four corners inside the protective frame, the tops of the four rubber pads are fixedly connected to the same dry-type transformer, a rectangular frame is fixedly connected to the top of the outer wall of the bottom plate, and the rectangular frame is connected to the bottom plate, a rectangular hole is opened at the top of the rectangular frame, two side straight holes are opened on both sides of the rectangular frame, first T-shaped blocks are slidably connected to the two ends of the top two side straight holes, the same first sliding frame is fixedly connected between the four first T-shaped blocks, the two ends of the bottom two side straight holes are slidably connected to the second T-shaped blocks, the same second sliding frame is fixedly connected between the four second T-shaped blocks, a plurality of first V-shaped plates are fixedly connected to the two sides of the first sliding frame at equal distances, a plurality of second V-shaped plates are fixedly connected to the two sides of the second sliding frame at equal distances, and the plurality of first V-shaped plates and the second V-shaped plates are staggered with each other.

[0006] As a further solution of the present invention, springs are fixedly connected at both ends of the outer wall of the first sliding frame, and the other end of each spring is fixedly connected to the inner wall of the rectangular frame. A rotating shaft is rotatably connected to the middle part of both sides of the inner wall of the rectangular frame, and a rotating rod is fixedly connected to the side close to the two rotating shafts. Straight holes are opened at both ends of the two rotating rods, and the first sliding rods are slidably connected in the two top straight holes. The two first sliding rods are fixedly connected to the outer wall of the first sliding frame, and the second sliding rods are slidably connected to the bottom of the two bottom straight holes, and the two second sliding rods are fixedly connected to the outer wall of the second sliding frame.

[0007] As a further solution of the present invention, the bottom of the two rotating rods are fixedly connected to a first diagonal rod, the bottom of the two first diagonal rods are fixedly connected to the same cross rod, and the middle of the cross rod is fixedly connected to two second diagonal rods. The fan blades push the two second diagonal rods so that when the fan blades rotate, the rotating rods can be driven to rotate, thereby aligning the multiple first V-shaped plates with the second V-shaped plates.

[0008] As a further solution of the present invention, the same connecting plate is fixedly connected on both sides of the top of the protective frame, a motor is fixedly sleeved in the middle of the connecting plate, and a square rod is fixedly connected to the output end of the top of the motor, a fan blade and a sliding column are provided on the sliding sleeve near the top of the square rod, and the sliding column is located at the bottom of the fan blade, and square holes matching the square rod are provided on the sliding column and the fan blade. The arrangement of the sliding column, the square rod and the fan blade ensures that when the fan blade rotates, it will be affected by the reaction force of the air and the fan blade will gradually drop, and the sliding column is matched with the second inclined rod, and the top of the square rod is fixedly connected to a limiting block.

[0009] As a further solution of the present invention, sound-absorbing cotton is fixedly connected to the inside of the protective frame. The provision of the sound-absorbing cotton facilitates the absorption of noise inside the protective frame, and a temperature sensor and a controller are fixedly connected to the top of the inner side of the protective frame, and the controller is electrically connected to the temperature sensor and the motor respectively.

[0010] As a further solution of the present invention, a square frame is fixedly sleeved in the middle of the bottom of the base plate, a square hole matching the square frame is opened at the bottom of the base plate, a fixed plate is fixedly connected to the inner wall of the square frame, and a plurality of thin tubes are fixedly sleeved at equal distances on the fixed plate, and a conical cover is fixedly connected to the bottom of each of the thin tubes. Through the arrangement of the thin tubes and the conical cover, air can easily enter the interior of the protective frame, and the noise waves inside the protective frame are not easy to diffuse out.

[0011] As a further solution of the present invention, both ends of the bottom of the base plate are fixedly connected with support legs, the top of the protective frame is fixedly connected with a ceiling through a support rod, and the ceiling is adapted to the rectangular frame. The top of the rectangular frame can be protected by the ceiling to prevent impurities and rainwater from entering the interior of the protective frame.

[0012] The beneficial effects of the present invention are: The present invention adopts the technical means of the first sliding frame, the second sliding frame, the first V-shaped plate, the second V-shaped plate, the rotating rod, the second oblique rod and the fan blades. During normal use, when the dry-type transformer inside the protective frame dissipates heat naturally, the multiple first V-shaped plates and the second V-shaped plates are interlaced with each other, so that the noise sound waves inside the protective frame are not easy to diffuse out. In combination with the sound-absorbing cotton, a good noise reduction effect is achieved. When active heat dissipation is required, when the fan blades rotate, the first V-shaped plate is aligned with the second V-shaped plate, so that air can be quickly discharged, thereby improving the active heat dissipation efficiency and effectively solving the problems raised in the background technology. Furthermore, on the basis of not affecting the natural heat dissipation and noise reduction function of the dry-type transformer, its active heat dissipation efficiency is effectively improved, and an optimal balance between noise reduction and heat dissipation performance is achieved, which not only overcomes the disadvantage that the noise reduction measures of the traditional dry-type transformer may affect the heat dissipation, but also enhances the active heat dissipation capacity, thereby improving the overall operation stability and reliability of the dry-type transformer.

[0013] The present invention: through the arrangement of the thin tube and the conical cover, the air at the bottom can easily enter the inside of the protection frame, but the noise sound waves inside the protection frame cannot be easily diffused out through the thin tube and the conical cover.

[0019] In this embodiment, springs 706 are fixedly connected at both ends of the outer wall of the first sliding frame 704, and the other end of each spring 706 is fixedly connected to the inner wall of the rectangular frame 7. The middle parts of the two sides of the inner wall of the rectangular frame 7 are rotatably connected with rotating shafts 710, and the sides close to the two rotating shafts 710 are fixedly connected with rotating rods 711. Straight holes 712 are opened at both ends of the two rotating rods 711, and the first sliding rods 713 are slidably connected in the two top straight holes 712. The two first sliding rods 713 are fixedly connected to the outer wall of the first sliding frame 704, and the second sliding rods 714 are slidably connected at the bottom of the two bottom straight holes 712, and the two second sliding rods 714 are fixedly connected to the outer wall of the second sliding frame 707.

[0020] In this embodiment, the bottoms of the two rotating rods 711 are fixedly connected to the first oblique rods 8 , the bottoms of the two first oblique rods 8 are fixedly connected to the same cross rod 801 , and the middle of the cross rod 801 is fixedly connected to two second oblique rods 802 .

[0021] In this embodiment, the same connecting plate 9 is fixedly connected to both sides of the top of the protective frame 2, a motor 901 is fixedly sleeved in the middle of the connecting plate 9, and a square rod 902 is fixedly connected to the top output end of the motor 901, and a fan blade 903 and a sliding column 904 are slidingly sleeved near the top of the square rod 902, and the sliding column 904 is located at the bottom of the fan blade 903, and square holes matching the square rod 902 are opened on the sliding column 904 and the fan blade 903, and the sliding column 904 is matched with the second inclined rod 802, and a limited block is fixedly connected to the top of the square rod 902. Through the sliding setting of the fan blade 903 and the sliding column 904, the fan blade 903 will gradually decline under the reaction force of the air when it rotates, driving the second inclined rod 802 to deflect.

[0022] In this embodiment, the protective frame 2 is fixedly connected to the inside with sound-absorbing cotton 4, and the top of the inner side of the protective frame 2 is fixedly connected to the temperature sensor 5 and the controller, and the controller is electrically connected to the temperature sensor 5 and the motor 901 respectively. Through the setting of the temperature sensor 5, active heat dissipation can be performed when natural heat dissipation is insufficient.

[0023] In this embodiment, a square frame 102 is fixedly sleeved in the middle of the bottom of the base plate 1, a square hole matching the square frame 102 is opened at the bottom of the base plate 1, a fixing plate 103 is fixedly connected to the inner wall of the square frame 102, and a plurality of thin tubes 104 are fixedly sleeved at equal distances on the fixing plate 103, and a conical cover 105 is fixedly connected to the bottom of each thin tube 104. The arrangement of the thin tubes 104 and the conical cover 105 facilitates the entry of airflow, but the noise sound waves inside the protective frame 2 are not easy to spread to the outside of the protective frame 2.

[0024] In this embodiment, both ends of the bottom of the base plate 1 are fixedly connected to support legs 101, and the top of the protective frame 2 is fixedly connected to a ceiling 202 through a support rod, and the ceiling 202 is adapted to the rectangular frame 7. The setting of the ceiling 202 prevents impurities such as rainwater from entering the top of the rectangular frame 7.

[0025] Working principle: when the transformer is in use, when the dry-type transformer 601 is working, the protection frame 2 and the sound-absorbing cotton 4 are used to reduce the noise of the dry-type transformer 601, and the noise flowing out of the outside of the protection frame 2 is reduced. Through the arrangement of multiple thin tubes 104 and conical covers 105, the gas at the protection frame 2 is easy to circulate, while the sound waves inside the protection frame 2 are not easy to be discharged through the thin tubes 104 and the conical covers 105. At the same time, the top first sliding frame 704 and the second sliding frame 707 allow the hot air at the top of the protection frame 2 to flow out. At the same time, since the multiple first V-shaped plates 705 and the second V-shaped plates 709 are staggered, the noise sound waves inside the protection frame 2 are not easy to flow out through the rectangular frame 7, but the hot air at the top can be discharged through the gap. Through the arrangement of multiple first V-shaped plates 705 and the second V-shaped plates 709, the sound waves can rebound repeatedly and gradually dissipate. When the temperature sensor 5 detects the protection When the temperature inside the protective frame 2 is high and natural heat dissipation is insufficient, the motor 901 is turned on to rotate the square rod 902 with the fan blades 903. When the fan blades 903 blow air toward the top rectangular frame 7, the fan blades 903 and the sliding column 904 gradually move downward due to the reaction force of the air, and then push the two second inclined rods 802 through the sliding column 904. Under the action of the second inclined rods 802, the cross rod 801 and the first inclined rod 8, the two rotating rods 711 gradually rotate a little, so that under the action of the straight hole 712, the first sliding rod 713 and the second sliding rod 714, the second sliding frame 707 and the first sliding frame 704 are staggered by a small distance, and the spring 706 on one side is compressed. At this time, the multiple first V-shaped plates 705 and the second V-shaped plates 709 will be neatly arranged to facilitate the flow of air, so that the fan blades 903 can quickly discharge the hot air inside the protective frame 2.
