Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer noise reduction structure. Background Technology

[0002] Transformers generate noise during operation, which not only affects the quietness of the surrounding environment but may also interfere with people's daily life and work. Therefore, noise reduction structures are installed on transformers.

[0003] Currently, some methods for reducing transformer noise involve wrapping the transformer with a casing to achieve the desired effect. However, these noise-reducing casings are all of a fixed size. When different specifications of transformers require noise reduction, a single-size casing cannot be used, resulting in poor installation adaptability. Moreover, most noise-reducing casings are enclosed, which affects the transformer's heat dissipation efficiency. Summary of the Invention

[0004] This utility model provides a transformer noise reduction structure that can be installed on the outside of transformers of different specifications to reduce noise, improve the adaptability during installation, and ensure the heat dissipation efficiency of the transformer.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes a transformer noise reduction structure, including: a first noise reduction housing 1;

[0029] A second noise-reducing housing 2 is installed between the first noise-reducing housing 1 and the second noise-reducing housing 2. The first and second noise-reducing housings 1 and 2 are used to enclose the transformer, thereby reducing noise. A heat dissipation vent 3 is provided on the front and rear inner walls of both the first and second noise-reducing housings 1 and 2. When the transformer's fan dissipates heat, hot air first enters the interlayer cavity between the first and second noise-reducing housings 1 and 2 through the heat dissipation vent 3 and flows upwards. A rainproof baffle 4 is welded to the top of both the first and second noise-reducing housings 1 and 2. During rainy weather, the rainproof baffle 4 can also block rainwater from entering the interlayer cavity between the first and second noise-reducing housings 1 and 2. A locking block 5 is provided on the front and rear sides of the first noise-reducing housing 1, and the second... Two locking blocks 5 are symmetrically arranged on the front and rear sides of the noise reduction housing 2. During assembly, the round rods on the bottom sides of the fixing frame 7 can be inserted from top to bottom into the round holes between the two adjacent locking blocks 5. At this time, the round rods on the fixing frame 7 will lock the first noise reduction housing 1, the second noise reduction housing 2, and the adjacent second noise reduction housing 2, ensuring that the first noise reduction housing 1 and the second noise reduction housing 2 enclose the transformer inside. A fixing frame 7 is installed between the two adjacent locking blocks 5. The fixing frame 7 is used to lock and fix the first noise reduction housing 1 and the second noise reduction housing 2. A fixing plate 6 is welded to the bottom of the fixing frame 7. During installation, the expansion screws can be passed through the round holes on the fixing plate 6 and screwed into the ground, thus fixing the position of the fixing plate 6 and the fixing frame 7.

[0030] In this embodiment of the disclosure, such as Figures 1-6As shown, the fixing frame 7 is a T-shaped frame. A round rod is provided on the bottom of both the left and right sides of the fixing frame 7. A corresponding through round hole is also provided in the middle of the locking block 5. During assembly, the round rods on the bottom of both sides of the fixing frame 7 can be inserted from top to bottom into the round holes in the middle of the two adjacent locking blocks 5. At this time, the round rods on the fixing frame 7 will lock the first noise reduction housing 1, the second noise reduction housing 2 and the adjacent second noise reduction housing 2, ensuring that the first noise reduction housing 1 and the second noise reduction housing 2 enclose the transformer inside.

[0031] In this embodiment of the disclosure, such as Figure 5 and Figure 6 As shown, each of the first noise reduction housing 1 and the second noise reduction housing 2 has a sandwich cavity. The heat dissipation vents 3 are connected to the sandwich cavities in the first noise reduction housing 1 and the second noise reduction housing 2. When the transformer fan dissipates heat, the hot air will first enter the sandwich cavity in the first noise reduction housing 1 and the second noise reduction housing 2 through the heat dissipation vents 3 and flow upward. Finally, the hot air will be discharged upward through the rectangular openings at the top of the first noise reduction housing 1 and the second noise reduction housing 2 to achieve heat dissipation.

[0032] In this embodiment of the disclosure, such as Figures 1-3 As shown, when the first noise-reducing housing 1 and the second noise-reducing housing 2 are in close contact, and when the adjacent second noise-reducing housing 2 is in close contact, the round rods at the bottom of both sides of the fixing frame 7 can be inserted into the round holes in the middle of the locking blocks 5. At the same time, the adjacent rainproof baffles 4 will also be in close contact. During assembly, the round rods at the bottom of both sides of the fixing frame 7 can be inserted from top to bottom into the round holes in the middle of the two adjacent locking blocks 5. At this time, the round rods on the fixing frame 7 will lock the first noise-reducing housing 1, the second noise-reducing housing 2, and the adjacent second noise-reducing housing 2, ensuring that the first noise-reducing housing 1 and the second noise-reducing housing 2 enclose the transformer inside.

[0033] In this embodiment of the disclosure, such as Figures 1-6 As shown, both the first noise-reducing housing 1 and the second noise-reducing housing 2 have a rectangular opening at their tops. A rainproof baffle 4 is installed above the rectangular openings at the tops of the first noise-reducing housing 1 and the second noise-reducing housing 2. When the transformer fan is dissipating heat, hot air will first enter the interlayer cavity in the first noise-reducing housing 1 and the second noise-reducing housing 2 through the heat dissipation vent 3 and flow upwards. Finally, this hot air will be discharged upwards through the rectangular openings at the tops of the first noise-reducing housing 1 and the second noise-reducing housing 2 to achieve heat dissipation. In rainy weather, the rainproof baffle 4 can also block rainwater and prevent rainwater from entering the interlayer in the first noise-reducing housing 1 and the second noise-reducing housing 2.

[0034] In this embodiment of the disclosure, such as Figures 1-6As shown, the top surfaces of the first noise-reducing housing 1 and the second noise-reducing housing 2 are two inclined surfaces, and the rainproof baffle 4 is an inverted V-shaped plate. In rainy weather, the rainproof baffle 4 can also block rainwater and prevent rainwater from entering the interlayer inside the first noise-reducing housing 1 and the second noise-reducing housing 2. Moreover, the inclined surfaces of the top of the first noise-reducing housing 1 and the second noise-reducing housing 2 as well as the top of the rainproof baffle 4 facilitate the outward flow of rainwater.

[0035] Example 2, based on Example 1, such as Figures 1-6 As shown, several strip grooves are equidistantly arranged on the inner wall of the interlayer cavity in the first noise reduction housing 1 and the second noise reduction housing 2, and several round holes are also provided on both sides of the strip grooves. When the transformer is working, the porous structure in the first noise reduction housing 1 and the second noise reduction housing 2 can play a role in noise reduction.

[0036] The working principle of this embodiment is as follows: When installing this structure, first install one of the first noise-reducing housings 1 on one side of the transformer. Then, install the second noise-reducing housing 2 on the top outer side of the transformer, ensuring that one outer wall of the second noise-reducing housing 2 is tightly against the outer wall of the first noise-reducing housing 1. If the transformer is wide, the number of second noise-reducing housings 2 can be increased according to the width of the transformer. Finally, install the other first noise-reducing housing 1 on the other side of the second noise-reducing housing 2. Then, insert the round rods at the bottom of both sides of the fixing bracket 7 into the round holes between the two adjacent locking blocks 5 from top to bottom until the bottom surface of the fixing plate 6 is tightly against the ground. At this point, the expansion screws can be passed through the round holes on the fixing plate 6 and screwed into the ground, thus fixing the position of the fixing plate 6 and the fixing bracket 7. At this time, the fixing bracket 7 will also press the locking blocks 5 downwards, thus firmly securing the positions of the first noise-reducing housing 1 and the second noise-reducing housing 2. The fixing bracket 7 also locks the first noise reduction housing 1, the second noise reduction housing 2, and the adjacent second noise reduction housing 2 together, ensuring that the first noise reduction housing 1 and the second noise reduction housing 2 enclose the transformer inside. When the transformer is working, the porous structure in the first noise reduction housing 1 and the second noise reduction housing 2 can play a role in noise reduction. Moreover, when the transformer fan dissipates heat, the hot air will first enter the interlayer cavity in the first noise reduction housing 1 and the second noise reduction housing 2 through the heat dissipation vent 3 and flow upward. Finally, this hot air will be discharged upward through the rectangular opening at the top of the first noise reduction housing 1 and the second noise reduction housing 2 to achieve heat dissipation. In rainy weather, the rainproof baffle 4 can also block rainwater and prevent rainwater from entering the interlayer in the first noise reduction housing 1 and the second noise reduction housing 2. In addition, the inclined surfaces at the top of the first noise reduction housing 1 and the second noise reduction housing 2 and the top of the rainproof baffle 4 also facilitate the outward flow of rainwater.
