Description

Technical Field

[0001] The present application relates to the technical field of transformers, and in particular to an energy-saving and low-noise three-phase power transformer. Background Art

[0002] In modern power systems, transformers are core equipment for power conversion and distribution. Their performance directly impacts the efficiency and quality of power transmission. With the growing demand for electricity and the increasing focus on energy efficiency, transformer technology continues to develop and innovate. Energy-saving, low-noise three-phase power transformers have become a key development direction for the industry. They not only reduce energy consumption and operating costs, but also minimize noise pollution to the surrounding environment, improving the working and living environment. Traditional transformer technology often uses vibration damping elements such as rubber pads and springs to reduce vibration and noise during operation. These damping elements can absorb and buffer vibration energy to a certain extent, thereby reducing the impact of vibration on the surrounding environment. Common methods for dissipating heat from transformers include air cooling and oil cooling. Air cooling uses a fan to blow air through the transformer's heat sink to remove heat, while oil cooling utilizes the thermal conductivity of the transformer oil to transfer heat to the radiator for dissipation. To ensure proper operation of the transformer, temperature sensors and control systems are also installed to automatically activate cooling devices when the temperature rises. However, traditional vibration damping and heat dissipation methods have certain limitations. Vibration-damping components like rubber pads and springs have limited effectiveness and cannot fully absorb the vibration energy generated during transformer operation. As a result, some vibration is still transmitted to the surrounding environment, generating noise. Air and oil cooling methods consume a lot of energy and can be ineffective in high-temperature environments, shortening the transformer's service life. Furthermore, traditional transformers lack effective utilization of vibration energy, resulting in energy waste. Summary of the Invention

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1 -Attached Figure 10 , further details of this application are given.

[0026] An energy-saving and low-noise three-phase power transformer, referring to Figure 1, comprising a transformer body 1, an energy-saving and noise-reduction system, and an evaporative water cooling system. The evaporative water cooling system dissipates heat and cools the transformer body 1 to ensure its normal operation. The energy-saving and noise-reduction system reduces the noise generated by the transformer body 1 during operation by recovering vibration energy during operation, reducing its propagation and converting it into electrical energy to support the operation of the evaporative water cooling system.

[0027] Reference Figure 1 、 Figure 2 The energy-saving and noise reduction system includes an installation box 2, which has an installation cavity formed therein. A sound insulation sponge 3 is fixedly connected to the inner wall of the installation cavity, wherein the sound insulation sponge 3 is made of foam aluminum with a porosity of 80%. In addition, a number of conical vibration damping blocks 4 are fixedly connected to the inner wall of the installation cavity, wherein the conical vibration damping blocks 4 are arranged through the sound insulation sponge 3. In addition, the end with a larger diameter on the conical vibration damping block 4 is fixedly connected to the inner wall of the installation cavity, and the end with a smaller diameter is fixedly connected to the vibration damping box 5, and the transformer body 1 is fixedly connected to the vibration damping box 5. The conical vibration damping block 4 adopts a multi-layer rubber and metal composite structure. When it is vibrated, the middle conical rubber part will produce a large shear deformation after being subjected to force. At the same time, it has a low natural frequency and a large deformation range, which can effectively absorb vibration energy.

[0028] A number of piezoelectric ceramic discs 6 corresponding to the conical damping blocks 4 are fixedly attached to the surface of the vibration damping box 5. Each piezoelectric ceramic disc 6 contacts the smaller end of the corresponding conical damping block 4. Furthermore, the polarization direction of the piezoelectric ceramic discs 6 is perpendicular to the vibration plane. Furthermore, the piezoelectric ceramic discs 6 are connected to a battery 7 via wires, which is fixedly attached to the mounting box 2. This ensures that when the transformer body 1 is operating, the vibration energy it generates is transmitted to the surface of the vibration damping box 5, causing the piezoelectric ceramic discs 6 on the surface to continuously and regularly press against the conical damping blocks 4, thereby converting the vibration energy into electrical energy and storing it in the battery 7.

[0029] Reference Figure 2 、 Figure 3 A rotation groove is provided on the inner wall of the mounting cavity, and a swing plate 8 passes through the rotation groove. Rotation shafts are fixedly connected on both sides of the swing plate 8, and the rotation shafts are rotationally connected to the inner wall of the rotation groove on the corresponding side. A sliding groove is provided on the side of the swing plate 8 close to the vibration damping box 5, and a shaking plate 9 is slidingly connected to the inner wall of the sliding groove. The end of the shaking plate 9 away from the mounting box 2 is fixedly connected to the surface of the vibration damping box 5, wherein the shaking plate 9 is a soft metal sheet. When the transformer body 1 is in operation, part of the vibration energy generated by the vibration damping box 5 is transferred to the shaking plate 9, causing the shaking plate 9 to vibrate up and down, thereby causing the swing plate 8 to swing up and down, thereby further consuming the vibration energy generated by the transformer body 1 during operation.

[0030] Reference Figure 2 、 Figure 4The evaporative water cooling system includes a guide block 10 fixedly connected to the top surface of the installation box 2. The middle portion of the guide block 10 protrudes away from the installation box 2, and the protruding end is curved. The two sides of the guide block 10 smoothly transition with the top surface of the installation box 2. The outer surface of the installation box 2 is fixedly connected to the evaporation box 11, which consists of three water-blocking plates. The top surface of the evaporation box 11 is fixedly connected to the filter plate 12, which is flush with the top surface of the installation box 2. The filter plate 12 is provided with a plurality of filter holes. The outside rainwater or clean water can flow along the curved surface of the guide block 10 and then flow into the evaporation box 11 through the filter holes.

[0031] Reference Figure 4 、 Figure 5 An overflow port 13 is provided on the surface of the evaporation box 11 on the side away from the installation box 2. This overflow port 13 is angled outward and downward. When excess liquid in the evaporation box 11 overflows, it flows out through the overflow port 13, preventing backflow of liquid from the evaporation box 11. Furthermore, the end of the swing plate 8, away from the shaking plate 9, extends into the evaporation box 11. The swing plate 8 is positioned between the overflow port 13 and the filter plate 12, allowing it to continuously swing above the liquid level in the evaporation box 11. This increases the air velocity above the liquid level in the evaporation box 11 and, in turn, improves the evaporation efficiency of the liquid in the evaporation box 11. Furthermore, a waterproof leather cover 14 is fixedly attached to the swing plate 8 and is fixedly connected to the inner wall of the rotating trough. This waterproof cover 14 prevents liquid from splashing into the evaporation box 11 and allows it to pass through the rotating trough into the installation box 2.

[0032] Reference Figure 2 、 Figure 5 、 Figure 6 A connecting pipe 15 is fixedly connected to the bottom of the evaporation box 11. This connecting pipe 15 is connected to a filter box 16 fixedly attached to the outer surface of the mounting box 2. A first filter 17 is fixedly connected to the inner wall of the end of the connecting pipe 15 that connects to the bottom of the evaporation box 11. Multiple second filters 18 are fixedly connected to the filter box 16. One of the second filters 18 is located on the inner wall of the end of the connecting pipe 15 that connects to the bottom of the filter box 16. The mesh size of the multiple second filters 18 increases as they are arranged closer to the top of the filter box 16. A 30W ultraviolet lamp 19 with an irradiation intensity of ≥100μW / cm² is fixedly connected to the top of the filter box 16. This ultraviolet lamp 19 is connected to the battery 7 via a wire to sterilize the liquid in the filter box 16.

[0033] Reference Figure 4 、 Figure 7The height of the top of the filter box 16 from the ground is greater than the height of the overflow port 13 of the evaporation box 11 from the ground. Furthermore, a balancing pipe 20 is inserted into the side of the filter box 16 near its top. A sealing plug 21 is slidably connected to the balancing pipe 20, and a telescopic airbag 22 is fixedly connected to the sealing plug 21. Furthermore, observation windows 23 are provided on the surfaces of the filter box 16 and the evaporation box 11 away from the mounting box 2, allowing personnel to visually check the liquid levels in the filter box 16 and the evaporation box 11.

[0034] Reference Figure 4 、 Figure 6 、 Figure 7 A siphon tube 24 is fixedly connected to the side of the filter box 16, and the height of the water inlet of the siphon tube 24 from the ground is lower than the height of the overflow port 13 from the ground. The siphon tube 24 is connected to a water storage tank 25 via a leather hose. The water storage tank 25 is fixedly connected to the outer surface of the installation box 2. A water exchange pipe 26 is fixedly connected to the surface of the water storage tank 25, and the water exchange pipe 26 is threadedly connected to the water exchange cap 27. Before use, the sealing plug 21 needs to be removed, and the "U"-shaped tube of the siphon tube 24 is pre-filled with water. Then, water is poured into the evaporation box 11 so that the liquid level in the filter box 16 is above the water inlet of the siphon tube 24. At this time, when the liquid level in the filter box 16 is higher than the water inlet of the siphon tube 24, a siphon effect is triggered, causing the liquid in the filter box 16 that is higher than the water inlet of the siphon tube 24 to flow into the water storage tank 25 under the action of the siphon effect.

[0035] Furthermore, when the liquid in the evaporation tank 11 needs to be replaced, the sealing plug 21 can be inserted into the balancing pipe 20 and the telescopic airbag 22 can be pulled outward, causing the air pressure in the filter box 16 to be lower than that in the evaporation tank 11. When the water level in the filter box 16 is higher than the water inlet of the siphon tube 24 due to the air pressure, the filter box 16 triggers a siphon effect, thereby transferring the liquid in the evaporation tank 11 into the water storage tank 25.

[0036] Reference Figure 2 、 Figure 4 、 Figure 6A cooling air generator 28 is fixedly connected to the surface of the mounting box 2. This cooling air generator 28 is connected to an electric gate valve 29 via a cooling air pipe. The electric gate valve 29 is also fixedly connected to the water tank 25. Both the cooling air generator 28 and the electric gate valve 29 are electrically connected to the battery 7. Furthermore, two water-cooling pipes 30 are fixedly connected to one side of the water tank 25. Both water-cooling pipes 30 penetrate the surface of the mounting box 2 and extend between the mounting box 2 and the vibration damping box 5. The water-cooling pipes 30 abut the outer surface of the vibration damping box 5 and the inner wall of the mounting box 2. The two water-cooling pipes 30 are connected by multiple branch pipes 31, each of which abuts the outer surface of the vibration damping box 5 and the inner wall of the mounting box 2. Both the water-cooling pipes 30 and the branch pipes 31 are made of EPDM rubber that can withstand 150°C. This allows them to cool the vibration damping box 5 while further absorbing vibration energy.

[0037] Reference Figure 8 、 Figure 9 A drive rod 32 is rotatably connected to the surface of the water tank 25 near the vibration damping box 5. One end of the drive rod 32 extends into the water tank 25, and the other end extends between the mounting box 2 and the vibration damping box 5. A first leaf 33 is fixedly connected to the portion of the drive rod 32 within the water tank 25. A sealing plate 34 is sleeved around the drive rod 32 within the water tank 25. Multiple coaxial sealing rings 35 of varying sizes are fixedly attached to the sealing plate 34. Furthermore, a corresponding number of sealing grooves 36 are defined within the water tank 25, corresponding to the number of sealing rings 35. Each sealing ring 35 is inserted into a correspondingly sized sealing groove 36, abutting against the inner wall of the groove 36.

[0038] Reference Figure 9 、 Figure 10 A vibration damping pad 37 is fixedly connected to the mounting box 2, and a drive motor 38 is fixedly connected to the vibration damping pad 37. The output shaft of the drive motor 38 is connected to the portion of the drive rod 32 between the mounting box 2 and the vibration damping box 5 via a belt. The drive motor 38 is also electrically connected to the battery 7. This allows the drive motor 38 to rotate the drive rod 32 and rotate the first leaf 33 within the water tank 25, thereby allowing the liquid in the water tank 25 to flow, thereby enhancing the water cooling effect of the vibration damping box 5.

[0039] A rotation hole is defined on the side of the vibration damping box 5 near the water tank 25, corresponding to the position of the drive rod 32. A rotation bearing 39 is fixedly connected to the inner wall of the rotation hole. A vibration damping ring 40 is fixedly connected to the inner ring of the rotation bearing 39. A rotation rod 41 is axially penetrated through the inner wall of the vibration damping ring 40. One end of the rotation rod 41 extends into the vibration damping box 5, and the other end of the rotation rod 41 extends between the installation box 2 and the vibration damping box 5. The portion of the rotation shaft that is fixed to the vibration damping box 5 is fixedly connected to a plurality of second leaves 42. The portion of the rotation rod 41 between the installation box 2 and the vibration damping box 5 is connected to the drive rod 32 via a magnetic coupling 43.

[0040] Reference Figure 2 、 Figure 9 、 Figure 10 The power part 4301 of the magnetic coupling 43 is fixedly connected to the driving rod 32, and the output part 4302 of the magnetic coupling 43 is fixedly connected to the rotating rod 41, and the air gap between the power part 4301 and the output part 4302 is 4 mm. In this way, when the transformer body 1 is working and drives the vibration damping box 5 to vibrate continuously at a low frequency, part of the vibration energy is absorbed by the vibration damping ring 40 and transmitted to the output part 4302 connected to the magnetic coupling 43 and the transmission rod, causing the output part 4302 to vibrate synchronously and continuously at a low frequency. Since a 4 mm air gap is set between the power part 4301 and the output part 4302, the output part 4302 can be prevented from colliding with the power part 4301 during vibration, thereby increasing the service life of the magnetic coupling 43.

[0041] Reference Figure 2 、 Figure 8 、 Figure 9 A rubber ventilation pipe 44 is fixedly connected to the surface of the mounting box 2, and one end of the ventilation pipe 44 is connected to the surface of the vibration damping box 5 near the second leaf 42, so that the outside air can flow into the vibration damping box 5 through the ventilation pipe 44. At the same time, the ventilation pipe 44 is fixedly connected to a dust cover 45, and the dust cover 45 is covered on the ventilation pipe 44.

[0042] Reference Figure 3 、 Figure 5 、 Figure 9 A rubber ventilation tube 46 is fixedly connected to the vibration damper housing 5. One end of the ventilation tube 46 penetrates the surface of the mounting box 2 and extends into the evaporation box 11. The outlet of the ventilation tube 46 is located between the swing plate 8 and the overflow port 13. This allows external airflow to enter the vibration damper housing 5 through the ventilation tube 44, supporting the rotation of the rotating rod 41, which then forms an airflow through the second leaf 42. The airflow generated by the rotation of the rotating rod 41 flows through the ventilation tube 46 into the evaporation box 11, thereby increasing the evaporation efficiency of the liquid in the evaporation box 11.

[0043] Reference Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 、 Figure 10The installation box 2 is rotatably connected to a door 47 at the installation cavity, and the door 47 opens or closes the installation cavity by rotating. A control panel 48 is fixedly connected to the door 47, and the control panel 48 is electrically connected to the battery 7, the drive motor 38, the cold air generator 28, the ultraviolet lamp 19, and the electric gate valve 29. A temperature sensor 49 is fixedly connected to the installation cavity and is electrically connected to the control panel 48. At the same time, a pressure sensor 50 is fixedly connected to the bottom surface of the water tank 25 and is electrically connected to the control panel 48. In this way, the battery 7, the drive motor 38, the cold air generator 28, the ultraviolet lamp 19, and the electric gate valve 29 are linked together by the temperature sensor 49 and the control panel 48 to achieve automatic cooling, which can effectively reduce manual intervention. At the same time, the staff can observe the temperature inside the vibration damping box 5 through the diameter of the control panel 48. In addition, when the pressure detected by the pressure sensor 50 is lower than the threshold, the pressure sensor 50 sends an electrical signal to the control panel 48, causing the control panel 48 to issue an alarm.

[0044] The implementation principle of the embodiment of the present application is: the present application achieves the dual goals of energy saving and consumption reduction and noise suppression through the coordinated design of vibration energy recovery, rainwater circulation cooling and multi-stage noise reduction structure of energy-saving and low-noise three-phase power transformer.

[0045] Vibrations generated by the transformer body 1 during operation are transmitted through the vibration damping box 5 to the conical damping mass 4 (a multi-layer rubber-metal composite structure). The conical design efficiently absorbs vibration energy through shear deformation, reducing vibration propagation. Simultaneously, the piezoelectric ceramic plates 6 (polarized perpendicular to the vibration plane) on the surface of the vibration damping box 5 are periodically squeezed by the conical damping mass 4, converting mechanical vibrations into electrical energy that is stored in the battery 7, achieving energy recovery.

[0046] The space between the vibration damping box 5 and the mounting box 2 is filled with 80% porosity aluminum foam 3 to block the propagation path of sound waves. The shaking plate 9 transmits some of the vibration to the swing plate 8 in the evaporation box 11. This swing plate 8 continuously disturbs the liquid surface, accelerating evaporation and further dissipating vibration energy. A magnetic coupling 43 (with a 4mm air gap) isolates the drive rod 32 from mechanical contact with the rotating rod 41, preventing vibration transmission to the cooling system.

[0047] Rainwater from the outside is collected by diversion block 10 and collected by filter plate 12, flowing into evaporation tank 11. The liquid then passes through first filter 17 (preliminary filtration) and second filter 18 (multi-stage precision filtration), and is sterilized by ultraviolet lamp 19 (irradiation intensity ≥ 100μW / cm²) to ensure clean water quality.

[0048] When the liquid level in the filter box 16 exceeds the water inlet of the siphon pipe 24, the siphon effect is triggered and the liquid automatically flows into the water storage tank 25. The balance pipe 20 and the sealing plug 21 regulate the air pressure to ensure the stability of the siphon.

[0049] Drive motor 38 (powered by battery 7) rotates drive rod 32, which in turn circulates the liquid within water tank 25. EPDM water-cooling tube 30 (resistant to 150°C) adheres tightly to the surface of vibration damper housing 5, absorbing heat and assisting in vibration reduction. Cooling air generator 28 (controlled by temperature sensor 49) activates at high temperatures to enhance cooling.

[0050] Driven by magnetic coupling 43, rotating rod 41 rotates second leaf 42, allowing outside air to enter damper housing 5 through vent pipe 44 (with dust cover 45). This airflow is then directed through ventilation pipe 46 into evaporator housing 11, where it is disturbed by swing plate 8, accelerating liquid evaporation and improving heat dissipation efficiency.

[0051] The temperature sensor 49 monitors the internal temperature of the vibration damping box 5 in real time, and the control panel 48 dynamically adjusts the speed of the drive motor 38 and the start and stop of the cold air generator 28. When the pressure sensor 50 detects abnormal pressure in the water tank 25, an alarm is triggered to ensure safe operation of the system.

[0052] Furthermore, recovered vibration energy powers the drive motor 38, UV lamp 19, and cooling system, reducing external energy consumption. The conical vibration damping blocks 4, sound-isolating sponge 3, and contactless magnetic transmission reduce noise levels to below 40dB. Rainwater reuse and evaporative heat dissipation reduce water consumption and achieve environmentally friendly operation.

[0053] This solution solves the problems of high energy consumption, reliance on external energy sources for heat dissipation, and incomplete vibration reduction in traditional transformers through the integrated design of vibration energy-electricity conversion, rainwater purification circulation, and multi-stage vibration isolation and noise reduction, thus achieving integrated control of "energy saving-noise reduction-efficient heat dissipation".

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
