Referring to fig. 1 and 2, an embodiment of the present invention provides a transformer 100, which includes a box 10, a transformer main body 20, and at least three first vibration dampers 30. The case 10 has a receiving cavity (not shown) therein, and the transformer body 20 is received in the receiving cavity. The first vibration damping assemblies 30 are arranged between the cavity bottom wall of the accommodating cavity and the transformer main body 20, each first vibration damping member 30 is provided with a first end 31 and a second end 32 which are oppositely arranged along the extending direction of the first vibration damping member, the first ends 31 of all the first vibration damping members 30 are mutually butted, and the second ends 32 are arranged at intervals along the circumferential direction of the cavity bottom wall of the accommodating cavity.

It should be noted that, in the operation process of the transformer 100, the transformer main body 20 often generates a large amount of heat, and in order to facilitate heat dissipation of the transformer main body 20, the transformer main body 20 is usually placed in a containing cavity of the tank 10, and transformer oil is filled in the containing cavity. When the transformer main body 20 is immersed in the transformer oil, the transformer oil can transfer heat generated from the transformer main body 20 to the tank 10, thereby achieving heat dissipation.

At present, when the transformer body 20 is directly placed on the cavity bottom wall of the accommodating cavity, the transformer body 20 is in rigid contact with the cavity bottom wall of the accommodating cavity. When the transformer main body 20 moves during operation or shakes during transportation, a rigid collision or a rigid friction is generated between the transformer main body 20 and the cavity bottom wall of the accommodating cavity. This easily causes damage to the structure of the transformer body 20. On the other hand, internal noise is also easily generated in the transformer 100, which affects the performance of the transformer 100.

Based on this, providing at least three first vibration dampers 30 between the cavity bottom wall of the accommodation cavity and the transformer body 20 can reduce the generation of rigid collision or rigid friction between the transformer body 20 and the cavity bottom wall of the accommodation cavity. This can prevent the structure of the transformer main body 20 from being damaged, and can also prevent noise pollution from occurring between the transformer main body 20 and the case 10.

In addition, all the first vibration dampers 30 are uniformly arranged on the cavity bottom wall of the accommodating cavity, so that multipoint vibration damping connection between the transformer main body 20 and the cavity bottom wall of the accommodating cavity can be realized, the transformer main body 20 can be more stably arranged in the accommodating cavity, and the vibration damping effect between the transformer main body 20 and the box body 10 can be improved.

In some embodiments, each of the first vibration damping members 30 is configured as a first elastic vibration damping pad, that is, the first vibration damping member 30 has elasticity, and when the first vibration damping member 30 is disposed between the bottom wall of the accommodating chamber and the transformer body 20, elastic connection of the bottom wall of the accommodating chamber and the transformer body 20 can be achieved, so that connection between the bottom wall of the accommodating chamber and the transformer body 20 is tighter.

Specifically, the first vibration damping member 30 may be configured as a silica gel or other elastic rubber pad, so as to achieve elastic connection between the bottom wall of the cavity and the transformer body 20, and avoid rigid collision or friction between the two.

As shown in fig. 3, the second ends 32 of all the first damper members 30 are arranged uniformly in the circumferential direction of the bottom wall of the accommodating chamber.

In this embodiment, the number of the first damping members 30 is three, each of the first damping members 30 has a first end 31 and a second end 32 which are oppositely arranged along the extending direction thereof, the first ends 31 of the three first damping members 30 are mutually butted, and the second ends 32 are uniformly arranged along the circumferential direction of the bottom wall of the accommodating cavity.

In the conventional transformer body 20, a three-dimensional wound core is used, and a coil 22 is wound around a core column of the three-dimensional wound core. The three-dimensional roll core is generally constructed in a triangular prism structure, and the cross section of the three-dimensional roll core is in a regular triangle shape.

Therefore, the three first vibration dampers 30 are respectively arranged along three perpendicular bisectors on the cross section of the three-dimensional wound core, that is, the first ends 31 of the three first vibration dampers 30 are arranged at the central positions of the regular triangle, so that the first ends 31 of the three first vibration dampers 30 are butted with each other, and the second ends 32 of the three first vibration dampers 30 respectively extend outwards. Thereby, the three first vibration dampers 30 can stably dispose the transformer main body 20 in the accommodation chamber, and can achieve elastic connection between the transformer main body 20 and the chamber bottom wall of the accommodation chamber.

Further, the first end 31 of each first damping member 30 is disposed at an angle of 120 °. Therefore, the first ends 31 of the three first vibration damping members 30 can be spliced into 360 degrees, the flatness of the spliced first ends 31 of the three first vibration damping members 30 can be kept, and the transformer main body 20 is stably supported on the first vibration damping members 30.

Referring to fig. 1, 2 and 4 together, in some embodiments, a receiving gap 11 is formed between the transformer body 20 and a cavity side wall of the receiving cavity, and the second ends 32 of all the first vibration dampers 30 extend into the receiving gap 11. The transformer 100 includes a limiting assembly 40, and the limiting assembly 40 is disposed between the bottom wall of the accommodating cavity and the second end 32 of each first damping member 30, so that the second end 32 of each first damping member 30 is raised above the bottom surface of the transformer body 20 to limit the transformer body 20.

The setting of spacing subassembly 40 can be located the cavity diapire that holds the chamber with transformer body 20 stable fixed, avoids transformer body 20 to take place to remove and leads to its structural damage.

The limiting component 40 can further improve the stability of the transformer main body 20 in the accommodating cavity, and reduce the probability of the transformer main body 20 moving in the accommodating cavity, thereby reducing the possibility of rigid collision or rigid friction between the transformer main body 20 and the bottom wall of the accommodating cavity.

In some embodiments, the limiting assembly 40 includes at least three limiting members 41, and each limiting member 41 is disposed in one-to-one correspondence with the second end 32 of each first damping member 30.

Specifically, the limiting members 41 are disposed between the second end 32 of each first damping member 30 and the bottom wall of the accommodating cavity in a one-to-one correspondence.

When the first vibration damping members 30 are three, the limiting members 41 are correspondingly three and are uniformly arranged along the circumferential direction of the bottom wall of the accommodating cavity, that is, the three limiting members 41 enclose to form a regular triangle. Therefore, the three limiting members 41 are uniformly distributed, and the stability of the transformer main body 20 supported thereon can be ensured.

Further, the height of each limiting member 41 gradually increases from the first end 31 of the corresponding first damping member 30 to the second end 32. Specifically, each of the stoppers 41 is provided in a triangular prism structure. Therefore, all the limiting members 41 surround the periphery of the transformer main body 20 along the circumferential direction of the bottom wall of the accommodating cavity, and can limit the transformer main body 20 along the periphery of the transformer main body 20, so that the transformer main body 20 is prevented from moving.

Referring to fig. 5 and 6, in some embodiments, the transformer 100 includes a noise reduction element 50, and the noise reduction element 50 is disposed on a cavity sidewall of the accommodating cavity and corresponds to a position of the transformer body 20.

The noise reduction assembly 50 is attached to the side wall of the cavity containing the cavity, so that when the transformer main body 20 works, the noise reduction assembly 50 can play a role in isolating noise, and noise reduction is achieved.

Specifically, in order to improve the heat dissipation performance of the transformer 100, a heat dissipation port is usually opened on a side wall of the casing 10, and the corrugated sheet 12 is hermetically disposed at the heat dissipation port. The corrugated sheet 12 can increase the contact area with the oil of the transformer 100 in the tank 10, thereby increasing the heat dissipation area of the transformer 100 and further improving the heat dissipation performance of the transformer 100.

Therefore, the noise reduction assembly 50 can be arranged in the heat dissipation port, noise is isolated through the noise reduction assembly 50, and noise reduction is achieved on the basis that the heat dissipation performance of the transformer 100 is not affected.

In some embodiments, noise reduction assembly 50 includes acoustic insulator mats disposed on the sidewalls of the receiving cavity. Specifically, the sound insulation pad may be a sound insulation rubber pad, or other sound insulation materials such as sound insulation cotton, which are not described herein.

Referring to fig. 7, in some embodiments, the transformer 100 includes an angle plate 61, a hanging plate 62, and a connecting member 63, wherein one end of the angle plate 61 is connected to the top wall of the cavity of the accommodating cavity, and the other end of the angle plate 61 is connected to one end of the hanging plate 62 through the connecting member 63. The other end of the hanging plate 62 is connected to the transformer body 20 to hang the transformer body 20 in the accommodation chamber.

When the three-dimensional roll iron core 21 in the transformer main body 20 is the three-dimensional amorphous alloy roll iron core 21, since the amorphous alloy material is thin and brittle, in order to avoid the three-dimensional roll iron core 21 from being subjected to the external force action of the wall of the accommodating cavity, the three-dimensional roll iron core 21 can be hung in the accommodating cavity through the hanging plate 62. Specifically, the angle plate 61 may be an L-shaped angle plate 61, and one of the extending plates perpendicular to each other is fixedly connected with the top wall of the accommodating cavity, and the other extending plate is fixedly connected with the hanging plate 62 through a connecting member 63. Thereby, the transformer body 20 can be suspended in the accommodation chamber.

Specifically, the connecting member 63 may be configured as a connecting bolt and nut, i.e., a bolt connecting one of the extending plates of the angle plate 61 and the hanging plate 62. It is understood that in some other embodiments, the connecting member 63 can be configured with other connecting structures as long as the fixed connection between the angle plate 61 and the hanging plate 62 can be achieved, and the details are not described herein.

However, in the above structure, the extending plate on one side of the angle plate 61 is rigidly connected to the hanging plate 62, and the transformer main body 20 is hung in the accommodating cavity by the hanging plate 62. Therefore, when the transformer main body 20 shakes, the gusset 61 and the hanger plate 62 are likely to rigidly collide with each other, thereby generating noise.

Therefore, in some embodiments, the transformer 100 includes the second vibration damper 70 disposed between the angle plate 61 and the hanger plate 62, and the connection member 63 is sequentially inserted through the angle plate 61, the second vibration damper 70, and the hanger plate 62. The second vibration damper 70 can achieve a buffering effect between the gusset 61 and the hanger plate 62, and prevent a rigid collision between the gusset 61 and the hanger plate 62, thereby reducing internal noise generated inside the transformer 100.

Further, the second vibration damper 70 is configured as a second elastic vibration damper pad. When the second vibration dampers 70 are provided between the gusset 61 and the hanger plate 62, elastic connection therebetween can be achieved. On the one hand, the connection between the corner plate 61 and the hanger plate 62 can be made tighter. On the other hand, the rigid collision between the gusset 61 and the hanger plate 62 can be converted into the elastic collision, thereby achieving vibration and noise reduction.

Referring to fig. 8 and 9, in some embodiments, the transformer body 20 includes an iron core 21 and a coil 22 wound on the iron core 21, and the transformer 100 includes a damping member 80, and the damping member 80 is disposed between the iron core 21 and the coil 22.

Specifically, the iron core 21 is an amorphous alloy three-dimensional roll iron core, that is, the iron core 21 is formed by winding an amorphous alloy strip. Therefore, the material of the core 21 is soft, which is characterized in that the core 21 is easily collapsed if the core 21 is directly placed on the ground, i.e., the height of the core 21 and the height of the window are reduced. If the lower end face of the yoke is lifted by a tool on the iron core 21, the iron core 21 is stretched, that is, the height of the iron core 21 and the height of the window become high. Based on this, in order to avoid the collapse of the iron core 21 in operation, the transformer body structure is set to be an iron core suspension structure.

The iron core suspension structure specifically includes that the lower frame 24 supports a lower insulating cushion block, the lower insulating cushion block supports the coil 22, the coil 22 supports the vibration damping assembly 80, and the vibration damping assembly 80 supports the iron core 21. Thereby, the entire weight of the core 21 is concentrated on the damper assembly 80. Further, the levitation height of the iron core 21 is set to 10mm to 15mm.

Referring to fig. 8 and 10, in some embodiments, the damping assembly 80 includes a supporting plate 81 and a third damping member 82, the supporting plate 81 and the third damping member 82 are sequentially disposed between the coil 22 and the core 21 along a direction in which the coil 22 points to the core 21, and a through groove 811 is opened on a side surface of the supporting plate 81 facing the coil 22.

Specifically, a side surface of the support plate 81 facing the coil 22 is opened with a through groove 811, and the through groove 811 can ensure the opening of the oil flow passage in the coil 22. In addition, the supporting plate 81 provides a supporting base between the coil 22 and the core 21. When the compression of the third damping member 82 is large due to the large pressure between the coil 22 and the core 21, the supporting plate 81 can perform a supporting function, and the through groove 811 formed on the supporting plate jointly ensures the smooth oil flow passage in the coil 22, thereby ensuring the normal operation of the transformer main body 20.

Further, the third vibration damper 82 is configured as a third elastic vibration damper pad. The third vibration damper 82 can convert a rigid collision between the core 21 and the coil 22 into an elastic collision, and prevent the core 21 from being damaged by an external force of the coil 22, thereby improving the structural stability of the core 21.

The transformer body 20 further includes an upper frame 23 and a lower frame 24 for fixing the core 21 and the coil 22. Specifically, the coil 22 is wound around a core column of the core 21, and then the core 21 is connected to the upper frame 23 and the lower frame 24 by gluing, and insulating spacers (not shown in the figure) are respectively disposed between the top end of the coil 22 and the upper frame 23, and between the bottom end of the coil 22 and the lower frame 24. Further, a tension screw 25 is provided between the upper frame 23 and the lower frame 24, and the iron core 21 and the coil 22 are fastened between the upper frame 23 and the lower frame 24 by the tension screw 25.

In order to prevent the coil 22 from exerting pressure on the core 21 during fastening by the tension screw 25, a support plate 81 and a third damper 82 are provided between the coil 22 and the core 21.

It should be noted that the iron core 21 is connected to the upper frame 23 and the lower frame 24 by gluing, specifically, a gluing hole is formed in the upper frame 23, wherein the diameter of the gluing hole is 10mm, and neutral glass glue is injected into the gluing hole to view the connection between the iron core 21 and the upper frame 23. Similarly, a glue hole is also provided in the lower frame 24, and neutral glass paste is injected into the glue hole to achieve connection between the core 21 and the lower frame 24.

On the other hand, the iron core 21 can be stably connected to the upper frame 23 and the lower frame 24 by gluing. On the other hand, the noise reduction function can be achieved to a certain extent.

When the transformer main body 20 is used in the concrete application, the upper frame 23 of the transformer main body 20 is firstly connected with the hanging plate 62, and the hanging plate 62 is fixed on the top wall of the cavity of the accommodating cavity through the angle plate 61 and the connecting piece 63, so that the transformer main body 20 is hung in the accommodating cavity. When the transformer body 20 shakes, the second vibration reduction member 70 provided between the angle plate 61 and the hanger plate 62 can provide buffering, thereby reducing noise.

Further, the upper frame 23 and the lower frame 24 are tightened by the tension screw 25, and the iron core 21 and the coil 22 are fastened between the upper frame 23 and the lower frame 24. Meanwhile, the iron core 21 and the coil 22 are buffered by the support plate 81 and the third vibration damper 82, so that the iron core 21 is prevented from being damaged by the external force of the coil 22, and the structural stability of the iron core 21 is ensured.

In addition, a stopper 41 and a first vibration damper 30 supported on the stopper 41 are provided between the lower frame 24 of the transformer main body 20 and the cavity bottom wall of the accommodation cavity. The limiting member 41 can limit the transformer body 20, and the transformer body 20 is prevented from moving in the accommodating cavity. Meanwhile, the first vibration damping member 30 can achieve a buffering effect between the transformer body 20 and the bottom wall of the accommodating cavity, and avoid rigid collision or rigid friction between the transformer body and the bottom wall of the accommodating cavity, so that vibration damping and noise reduction are achieved.

The noise reduction assembly 50 located on the cavity side wall of the receiving cavity enables sound insulation when the transformer body 20 is operated, thereby reducing noise pollution generated from the transformer 100.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
