Description

Technical Field

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

[0002] Transformers are critical equipment in power systems. During operation, they generate significant noise due to electromagnetic forces and the operation of cooling fans. This noise not only pollutes the surrounding environment, affecting residents' daily lives and work, but prolonged exposure to noise can also have adverse effects on human health. Furthermore, transformers have weak adaptive vibration damping capabilities, failing to adjust damping parameters promptly according to load changes and alterations in operating conditions, increasing the risk of equipment failure and reducing the reliability and stability of the power supply system.

[0003] A search revealed Chinese patent document (authorization announcement number CN222580919U), which discloses a transformer tank structure with noise reduction function, relating to the field of transformer tank technology. Through the arrangement of the transformer tank mechanism, the outer frame and the inner tank divide the tank into inner and outer layers. Oil is stored in the inner tank, and side sealing plates at both ends achieve side-mounted filling and vibration damping of the inner tank. Sound insulation cotton is filled between the inner tank and the outer frame. This device can meet basic usage requirements, but its adaptive vibration damping capability is weak. It cannot adjust the vibration damping parameters in a timely manner according to factors such as load changes and changes in operating conditions, increasing the risk of equipment failure and reducing the reliability and stability of the power supply system. Utility Model Content

[0004] The purpose of this invention is to provide a transformer tank structure with noise reduction function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transformer tank structure with noise reduction function, including a base, a top plate for protecting the transformer body is installed on the top of the base, two fixing parts are connected to the top of the top plate, and adjusting columns are welded to the ends of the two fixing parts; Each adjusting column has a cross-shaped circular groove inside, and a first spring is connected inside the cross-shaped circular groove. One end of the first spring is connected to a cross-shaped moving disk, which is slidably disposed inside the adjusting column. A guide post is welded inside the cross-shaped circular groove, and the guide post completely penetrates the interior of the cross-shaped moving disk. A locking post is connected to one side of the cross-shaped moving disk, and a threaded post for locking the cross-shaped moving disk is rotatably connected inside the locking post.

[0006] Preferably, one end of the cross-shaped moving disk is connected to a hollow column, the hollow column is slidably disposed on the top of the adjusting column, and the top of the adjusting column is provided with a groove for the hollow column to slide.

[0007] Preferably, the hollow column has a guide groove inside, and a second spring is connected to the inner bottom wall of the guide groove.

[0008] Preferably, one end of the second spring is connected to a guide plate, and the end of the guide plate away from the second spring is connected to a movable column.

[0009] Preferably, a connecting block is welded to the end of the movable column away from the guide plate, a support plate for fixing is welded to the end of the connecting block, and the oil tank body is installed on the top of the support plate.

[0010] Preferably, a base for fixing the transformer body is welded to the bottom of the transformer body, and heat dissipation parts are installed on both sides of the transformer body.

[0011] Preferably, the top of the top plate is equipped with a connection part for external connection, and the top of the transformer body is connected to a converter.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This transformer tank structure with noise reduction function benefits from the structure of the adjusting column and hollow column. The vertical compression of the tank body to the connecting block and the moving column drives the guide plate to compress the second spring. The guide plate moves inside the hollow column, which can reduce the vibration noise generated by the tank body in the vertical direction. When the tank body experiences lateral vibration noise, the hollow column drives the cross-shaped moving plate to move laterally within the cross-shaped circular groove. The first spring deforms, and the adjusting column can reduce the vibration noise generated by the tank body in the horizontal direction. Compared with traditional transformer tank structures with noise reduction function, which have weak adaptive vibration reduction capabilities, this structure can improve adaptive vibration reduction capabilities. It can adjust the vibration reduction parameters in a timely manner according to factors such as load changes and changes in operating conditions, reduce the risk of equipment failure, and improve the power supply reliability and stability of the power system.

[0013] This transformer tank structure with noise reduction function benefits from the threaded column and locking column design. When the position of the hollow column needs to be fixed, rotating the threaded column engages with the locking column to lock the position of the cross-shaped moving disc. This structure converts rotational motion into axial clamping force through the threaded pair, and then uses friction to achieve position locking. Further improvements in reliability are possible.

Detailed Implementation

[0017] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0019] like Figures 1 to 5 The transformer tank structure shown includes a base 1, a top plate 103 for protecting the transformer body 101 is installed on the top of the base 1, and two fixing parts 105 are connected to the top of the top plate 103. Adjusting columns 2 are welded to the ends of the two fixing parts 105. The interior of each adjusting column 2 is provided with a cross-shaped circular groove 201. A first spring 202 is connected inside the cross-shaped circular groove 201. One end of the first spring 202 is connected to a cross-shaped moving disk 203. The cross-shaped moving disk 203 is slidably disposed inside the adjusting column 2. A guide post 206 is welded inside the cross-shaped circular groove 201. The guide post 206 completely penetrates the interior of the cross-shaped moving disk 203. A locking post 204 is connected to one side of the cross-shaped moving disk 203. A threaded post 205 for locking the cross-shaped moving disk 203 is rotatably connected inside the locking post 204. A hollow post 3 is connected to one end of the cross-shaped moving disk 203. The hollow post 3 is slidably disposed on the top of the adjusting column 2. A groove 207 for sliding the hollow post 3 is provided on the top of the adjusting column 2. In the horizontal direction, when the tank body 4 experiences lateral vibration, the hollow column 3 drives the cross-shaped moving disk 203 to move laterally within the cross-shaped circular groove 201. At this time, the first spring 202, located within the cross-shaped circular groove 201, is compressed or stretched, causing deformation. Relying on its elastic properties, the first spring 202 hinders the lateral movement of the cross-shaped moving disk 203, absorbs vibration energy, and counteracts the impact of lateral vibration, thus suppressing the lateral vibration of the tank body 4 and reducing horizontal vibration noise. The vertical and horizontal vibration damping structures work together to comprehensively reduce the vibration generated during transformer operation, effectively reducing the impact of vibration noise on the surrounding environment.

[0020] The hollow column 3 has a guide groove 301 inside. A second spring 302 is connected to the inner bottom wall of the guide groove 301. One end of the second spring 302 is connected to a guide disk 303. The end of the guide disk 303 away from the second spring 302 is connected to a moving column 304. A connecting block 305 is welded to the end of the moving column 304 away from the guide disk 303. A support plate 306 for fixing is welded to the end of the connecting block 305. The tank body 4 is mounted on the top of the support plate 306. When the transformer generates vibration noise during operation, this structure works synergistically in both vertical and horizontal directions to reduce noise. In the vertical direction, the tank body 4 is subjected to vibration impact and presses the connecting block 305 downward, causing the moving column 304 to push the guide disk 303. The guide disk 303 moves downward inside the hollow column 3, compressing and deforming the second spring 302. The second spring 302 absorbs vibration energy through elastic deformation, converting the kinetic energy generated by the vibration into the elastic potential energy of the spring, buffering the vertical vibration of the tank body 4, reducing vibration transmission, and thus reducing vertical vibration noise.

[0021] The bottom of the transformer body 101 is welded with a base 1 for fixing the transformer body 101. Heat dissipation parts 102 are installed on both sides of the transformer body 101. A connection part 104 for connecting to the outside is installed on the top of the top plate 103. A converter 106 is connected to the top of the transformer body 101. The transformer body 101 is fixed by the base 1. The connection part 104 is connected to the outside. The converter 106 is connected to the oil tank body 4. The oil tank body 4 is connected to the top plate 103 through the adjusting column 2, the hollow column 3 and the fixing part 105. The transformer base 1 is firmly fixed to the ground with anchor bolts, providing stable support for the entire device. The transformer body 101 is mounted on the base 1 to ensure that it will not shift or shake during operation. The connection part 104 serves as the interface between the transformer and the external circuit, using copper busbars or cable connectors to achieve electrical connection, transmitting electrical energy from the transformer to the power grid or load. The converter 106 is responsible for adapting the electrical parameters and physical interface between the transformer body 101 and the tank body 4, ensuring smooth power transmission between them.

[0022] The tank body 4 is connected to the top plate 103 via the adjusting column 2, the hollow column 3, and the fixing part 105, forming a complete support structure. The adjusting column 2 typically employs a threaded structure, allowing its length to be adjusted by rotation to accommodate different installation heights and levelness requirements. The hollow column 3 integrates a spring shock absorber or a hydraulic damper, effectively absorbing vibrations and impacts generated during transformer operation and reducing the impact on the surrounding environment. The fixing part 105 is used to lock the position of the adjusting column 2, ensuring the stability of the entire support structure.

[0023] When the transformer is running, the heat generated is transferred to the tank wall through the insulating oil inside the tank body 4, and then dissipated into the air through the heat dissipation part 102. Simultaneously, the vibration-damping design of the hollow column 3 reduces the noise generated during transformer operation, minimizing interference with the surrounding environment. The entire structure, through modular design, facilitates installation, maintenance, and component replacement, improving the transformer's reliability and service life.

[0024] Working principle In use, the transformer tank structure with noise reduction function first fixes the transformer body 101 using the base 1, connects the external part 104, and connects the tank body 4 using the converter 106. The tank body 4 is connected to the top plate 103 through the adjusting column 2, hollow column 3 and fixing part 105. When vibration noise occurs, the tank body 4 vertically presses the connecting block 305 and the moving column 304, which drives the guide plate 303 to press the second spring 302. The guide plate 303 moves in the hollow column 3, which can reduce the vibration noise generated by the tank body 4 in the vertical direction. When the tank body 4 has lateral vibration noise, the hollow column 3 drives the cross moving plate 203 to move laterally in the cross circular groove 201, which deforms the first spring 202. The adjusting column 2 can reduce the vibration noise generated by the tank body 4 in the horizontal direction. If it is necessary to fix the position of the hollow column 3, the threaded column 205 is rotated, and the threaded column 205 cooperates with the locking column 204 to lock the position of the cross moving plate 203.
