Description

Technical Field

[0001] This application relates to the field of transformer technology, and in particular to an energy-saving, low-noise three-phase power transformer. Background Technology

[0002] In modern power systems, transformers, as core equipment for power conversion and distribution, directly impact the efficiency and quality of power transmission. With the continuous growth of electricity demand and increased focus on energy efficiency, transformer technology is constantly evolving and innovating. Energy-saving and low-noise three-phase power transformers have become an important direction for industry development because they not only reduce energy consumption and operating costs but also minimize noise pollution, improving the working and living environment. In traditional transformer technology, vibration damping components such as rubber pads and springs are typically used to isolate vibration transmission and reduce vibration and noise generated during operation. These components can absorb and buffer vibration energy to a certain extent, thus reducing the impact of vibration on the surrounding environment. Common methods for transformer heat dissipation include air cooling and oil cooling. Air cooling uses a fan to blow air across the transformer's heat sink, carrying away heat; oil cooling utilizes the thermal conductivity of transformer oil to transfer heat to the radiator for dissipation. To ensure normal transformer operation, temperature sensors and control systems are also installed to automatically activate cooling equipment when the temperature is too high. However, traditional vibration damping and heat dissipation methods have certain limitations. Vibration damping components such as rubber pads and springs have limited damping effects and cannot fully absorb the vibration energy generated during transformer operation, resulting in some vibrations still being transmitted to the surrounding environment and generating noise. Air cooling and oil cooling methods consume a lot of energy, and their cooling effect may be unsatisfactory in some high-temperature environments, affecting the transformer's service life. Furthermore, traditional transformers lack effective utilization of vibration energy, leading to energy waste. Summary of the Invention

[0044] The following is in conjunction with the appendix Figure 1 -Appendix Figure 10 This application will be described in further detail below.

[0045] An energy-saving and low-noise three-phase power transformer, with reference to Figure 1 The system includes 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 recovers the vibration energy generated by the transformer body 1 during operation, reduces the propagation of vibration energy to reduce the noise generated by the transformer body 1 during operation, and converts the vibration energy into electrical energy to support the operation of the evaporative water-cooling system.

[0046] Reference Figure 1 , Figure 2 The energy-saving and noise-reduction system includes a mounting box 2, which has a mounting cavity. Sound-insulating foam 3, made of aluminum foam with a porosity of 80%, is fixedly connected to the inner wall of the mounting cavity. Several conical vibration damping blocks 4 are fixedly connected to the inner wall of the mounting cavity, with each conical vibration damping block 4 penetrating the sound-insulating foam 3. The larger diameter end of each conical vibration damping block 4 is fixedly connected to the inner wall of the mounting cavity, while the smaller diameter end is fixedly connected to a vibration damping box 5. The transformer body 1 is fixedly connected inside the vibration damping box 5. The conical vibration damping block 4 adopts a multi-layer rubber and metal composite structure. When subjected to vibration, the central conical rubber portion undergoes significant shear deformation under stress. Simultaneously, it possesses a low natural frequency and a large deformation range, effectively absorbing vibration energy.

[0047] A number of piezoelectric ceramic sheets 6, corresponding to the conical vibration damping blocks 4, are fixedly connected to the surface of the vibration damping box 5. Each piezoelectric ceramic sheet 6 abuts against the smaller diameter end of a corresponding conical vibration damping block 4. Furthermore, the polarization direction of the piezoelectric ceramic sheet 6 is perpendicular to the vibration surface, and the piezoelectric ceramic sheet 6 is connected to a storage battery 7 via wires. The storage battery 7 is fixedly connected to the mounting box 2. This allows the vibration energy generated by the transformer body 1 to be transmitted to the surface of the vibration damping box 5 during operation, causing the piezoelectric ceramic sheets 6 on the surface to continuously and regularly compress against the conical vibration damping blocks 4, thereby converting the vibration energy into electrical energy and storing it through the storage battery 7.

[0048] Reference Figure 2 , Figure 3 The inner wall of the mounting cavity has a rotating groove, through which a swing plate 8 passes. Rotating shafts are fixedly connected to both sides of the swing plate 8, and these shafts are rotatably connected to the inner wall of the corresponding rotating groove. A sliding groove is provided on the side of the swing plate 8 closest to the vibration damping box 5. A vibrating plate 9 is slidably connected to the inner wall of the sliding groove. The end of the vibrating plate 9 furthest from the mounting box 2 is fixedly connected to the surface of the vibration damping box 5. The vibrating plate 9 is a soft metal sheet. When the transformer body 1 is running, some of the vibration energy generated by the vibration damping box 5 is transmitted to the vibrating plate 9, causing the vibrating plate 9 to vibrate up and down, thereby causing the swing plate 8 to swing up and down, further dissipating the vibration energy generated by the transformer body 1 during operation.

[0049] Reference Figure 2 , Figure 4 The evaporative water cooling system includes a guide block 10 fixedly connected to the top surface of the mounting box 2. The middle part of the guide block 10 protrudes away from the mounting box 2, and the protruding end is arc-shaped. The two sides of the guide block 10 smoothly transition to the top surface of the mounting box 2. An evaporator 11 consisting of three water-proof plates is fixedly connected to the outer surface of the mounting box 2. A filter plate 12 is fixedly connected to the top surface of the evaporator 11. The filter plate 12 is flush with the top surface of the guide block 10 on the mounting box 2. The filter plate 12 has several filter holes. External rainwater or clean water can flow along the arc-shaped surface of the guide block 10 and flow into the evaporator 11 through the filter holes.

[0050] Reference Figure 4 , Figure 5 An overflow port 13 is provided on the surface of the evaporator 11 away from the mounting box 2. The overflow port 13 is inclined outward and downward, allowing excess liquid in the evaporator 11 to flow out through the overflow port 13, thus preventing backflow. Additionally, the end of the swing plate 8 away from the vibrating plate 9 extends into the evaporator 11, and the swing plate 8 is located between the overflow port 13 and the filter plate 12. This allows the swing plate 8 to continuously swing above the liquid surface in the evaporator 11, increasing the air velocity on the liquid surface and improving the evaporation efficiency. Simultaneously, a water-proof sleeve 14 is fixedly connected to the swing plate 8. The water-proof sleeve 14 is fixedly connected to the inner wall of the rotating groove, preventing liquid from splashing into the evaporator 11 and allowing it to pass through the rotating groove into the mounting box 2.

[0051] Reference Figure 2 , Figure 5 , Figure 6 An evaporator 11 has a connecting pipe 15 fixedly connected to its bottom surface, and a filter box 16 fixedly connected to the outer surface of the mounting box 2 is connected through the connecting pipe 15. A first filter screen 17 is fixedly connected to the inner wall of the end of the connecting pipe 15 that connects to the bottom of the evaporator 11. Multiple second filter screens 18 are fixedly connected inside the filter box 16, with one second filter screen 18 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 filter screens 18 increases sequentially towards the top of the filter box 16. A 30W ultraviolet lamp 19 with an irradiation intensity ≥100μW / cm² is fixedly connected to the top of the filter box 16. The ultraviolet lamp 19 is connected to a battery 7 via a wire to sterilize the liquid inside the filter box 16.

[0052] Reference Figure 4 , Figure 7The top of the filter box 16 is higher than the overflow port 13 of the evaporator 11. A balance tube 20 is inserted into the side of the filter box 16 near its top, and a sealing plug 21 is slidably connected inside the balance tube 20. A telescopic airbag 22 is fixedly connected to the sealing plug 21. Furthermore, observation windows 23 are provided on the surfaces of both the filter box 16 and the evaporator 11 away from the mounting box 2, allowing operators to directly observe the liquid levels inside the filter box 16 and the evaporator 11.

[0053] Reference Figure 4 , Figure 6 , Figure 7 A siphon pipe 24 is fixedly connected to the side of the filter box 16, and the height of the inlet of the siphon pipe 24 from the ground is lower than the height of the overflow port 13 from the ground. The siphon pipe 24 is connected to a water storage tank 25 through a hose. The water storage tank 25 is fixedly connected to the outer surface of the mounting box 2, and a water exchange pipe 26 is fixedly connected to the surface of the water storage tank 25. The water exchange pipe 26 is threadedly connected to a water exchange cap 27. Before use, the sealing plug 21 needs to be removed, and water should be pre-filled into the "U"-shaped tube of the siphon pipe 24. Then, water is poured into the evaporator 11 so that the liquid level in the filter box 16 is above the inlet of the siphon pipe 24. When the liquid level in the filter box 16 is higher than the inlet of the siphon pipe 24, a siphon effect is triggered, causing the liquid in the filter box 16 that is higher than the inlet of the siphon pipe 24 to flow into the water storage tank 25 under the action of the siphon effect.

[0054] Additionally, when it is necessary to replace the liquid in the evaporator 11, the sealing plug 21 can be inserted into the balance tube 20, and the telescopic air bladder 22 can be pulled outward to make the air pressure in the filter box 16 lower than that in the evaporator 11. When the water level in the filter box 16 is higher than the inlet of the siphon tube 24 due to the air pressure, the filter box 16 triggers the siphon effect, thereby drawing the liquid in the evaporator 11 into the water storage tank 25.

[0055] Reference Figure 2 , Figure 4 , Figure 6A cooling air generator 28 is fixedly connected to the surface of the mounting box 2. The cooling air generator 28 is connected to an electric gate valve 29 via a cooling air pipe, and the electric gate valve 29 is fixedly connected to the water storage tank 25. Both the cooling air generator 28 and the electric gate valve 29 are electrically connected to the battery 7. Additionally, two water-cooling pipes 30 are fixedly connected to one side of the water storage tank 25. Both water-cooling pipes 30 penetrate the surface of the mounting box 2 and extend into the space between the mounting box 2 and the vibration damping box 5, and abut against 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, and each branch pipe 31 abuts against the outer surface of the vibration damping box 5 and the inner wall of the mounting box 2. Furthermore, the water-cooling pipes 30 and the branch pipes 31 are made of EPDM rubber, which can withstand temperatures up to 150℃, thus cooling the vibration damping box 5 while further absorbing the vibration energy on the vibration damping box 5.

[0056] Reference Figure 8 , Figure 9 A drive rod 32 is rotatably connected to the surface of the water storage tank 25 near the vibration damping box 5. One end of the drive rod 32 extends into the water storage tank 25, and the other end extends between the mounting box 2 and the vibration damping box 5. A first blade 33 is fixedly connected to the portion of the drive rod 32 inside the water storage tank 25. A sealing plate 34 is fitted onto the drive rod 32 inside the water storage tank 25, and multiple coaxial sealing rings 35 of different sizes are fixedly connected to the sealing plate 34. Simultaneously, a number of sealing grooves 36 corresponding to the number of sealing rings 35 are formed inside the water storage tank 25. Each sealing ring 35 is inserted into a sealing groove 36 of the same size, and the sealing ring 35 abuts against the inner wall of the sealing groove 36.

[0057] Reference Figure 9 , Figure 10 A vibration damping pad 37 is fixedly connected inside 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 drive rod 32 between the mounting box 2 and the vibration damping box 5 via a belt. At the same time, the drive motor 38 is electrically connected to the battery 7, so that when the drive motor 38 is running, it can drive the drive rod 32 to rotate, and cause the first blade 33 to rotate inside the water storage tank 25, thereby allowing the liquid in the water storage tank 25 to flow, thus increasing the water cooling effect of the vibration damping box 5.

[0058] The vibration damping box 5 has a rotating hole on the side near the water storage tank 25, corresponding to the position of the drive rod 32. A rotating bearing 39 is fixedly connected to the inner wall of the rotating hole, and a vibration damping ring 40 is fixedly connected to the inner ring of the rotating bearing 39. A rotating rod 41 is axially inserted through the inner wall of the vibration damping ring 40. One end of the rotating rod 41 extends into the vibration damping box 5, and the other end extends between the mounting box 2 and the vibration damping box 5. Several second blades 42 are fixedly connected to the part of the rotating shaft in the vibration damping box 5, and the part of the rotating rod 41 between the mounting box 2 and the vibration damping box 5 is connected to the drive rod 32 through a magnetic coupling 43.

[0059] Reference Figure 2 , Figure 9 , Figure 10 The power unit 4301 of the magnetic coupling 43 is fixedly connected to the drive rod 32, and the output unit 4302 of the magnetic coupling 43 is fixedly connected to the rotating rod 41. The air gap between the power unit 4301 and the output unit 4302 is 4mm. This allows some of the vibration energy to be absorbed by the damping ring 40 and transmitted to the output unit 4302 of the magnetic coupling 43 connected to the transmission rod when the transformer body 1 is working and driving the vibration damping box 5 to vibrate continuously at low frequency. This causes the output unit 4302 to vibrate synchronously and continuously at low frequency. Since there is a 4mm air gap between the power unit 4301 and the output unit 4302, it can prevent the output unit 4302 from colliding with the power unit 4301 during vibration, thereby increasing the service life of the magnetic coupling 43.

[0060] Reference Figure 2 , Figure 8 , Figure 9 A rubber vent pipe 44 is fixedly connected to the surface of the mounting box 2. One end of the vent pipe 44 is connected to the surface of the vibration damping box 5 near the second blade 42, so that outside air can flow directly into the vibration damping box 5 through the vent pipe 44. At the same time, a dust cover 45 is fixedly connected to the vent pipe 44 and covers the vent pipe 44.

[0061] Reference Figure 3 , Figure 5 , Figure 9 The vibration damping box 5 is fixedly connected to a rubber ventilation pipe 46. One end of the ventilation pipe 46 passes through the surface of the mounting box 2 and extends into the evaporator 11, with the outlet of the ventilation pipe 46 located between the swing plate 8 and the overflow port 13. This allows external airflow to enter the vibration damping box 5 through the ventilation pipe 44, supporting the rotation of the rotating rod 41 to form airflow through the second blade 42. The airflow formed after the rotating rod 41 rotates flows into the evaporator 11 through the ventilation pipe 46, thereby increasing the evaporation efficiency of the liquid in the evaporator 11.

[0062] Reference Figure 1 , Figure 2 , Figure 6 , Figure 8 , Figure 10The mounting box 2 is rotatably connected to a door 47 at the mounting cavity, which opens or closes the mounting cavity by rotation. A control panel 48 is fixedly connected to the door 47, and the control panel 48 is electrically connected to the battery 7, drive motor 38, air conditioning generator 28, ultraviolet lamp 19, and electric gate valve 29. A temperature sensor 49 is fixedly connected inside the mounting cavity and is electrically connected to the control panel 48. Simultaneously, a pressure sensor 50 is fixedly connected to the bottom surface inside the water storage tank 25 and is electrically connected to the control panel 48. This allows the battery 7, drive motor 38, air conditioning generator 28, ultraviolet lamp 19, and electric gate valve 29 to achieve automatic cooling through the linkage of the temperature sensor 49 and the control panel 48, effectively reducing manual intervention. Furthermore, operators can observe the internal temperature of the vibration damping box 5 through the control panel 48. Additionally, when the pressure detected by the pressure sensor 50 is below a threshold, the pressure sensor 50 sends an electrical signal to the control panel 48, causing the control panel 48 to issue an alarm.

[0063] The implementation principle of this application embodiment is as follows: This application achieves the dual goals of energy saving and noise suppression through the coordinated design of energy-saving and low-noise three-phase power transformers, including vibration energy recovery, rainwater circulation cooling, and multi-level noise reduction structures.

[0064] The vibration generated by the transformer body 1 during operation is transmitted to the conical vibration damping block 4 (multi-layer rubber-metal composite structure) through the vibration damping box 5. The conical design efficiently absorbs vibration energy through shear deformation, reducing vibration propagation. At the same time, the piezoelectric ceramic sheet 6 (polarization direction perpendicular to the vibration surface) on the surface of the vibration damping box 5 is periodically squeezed by the conical vibration damping block 4, converting mechanical vibration into electrical energy and storing it in the battery 7, thus realizing energy recovery.

[0065] The space between the vibration damping box 5 and the mounting box 2 is filled with 80% porosity aluminum foam sound insulation sponge 3 to block the sound wave propagation path. The vibration plate 9 transmits some of the vibration to the swing plate 8 inside the evaporation box 11. The swing plate 8 continuously disturbs the liquid surface to accelerate evaporation and further consumes vibration energy. The magnetic coupling 43 (air gap 4mm) isolates the mechanical contact between the drive rod 32 and the rotating rod 41 to prevent vibration from being transmitted to the heat dissipation system.

[0066] Rainwater from outside is collected by the guide block 10 and flows into the filter plate 12 and then into the evaporator 11. The liquid passes through the first filter screen 17 (preliminary filtration) and the second filter screen 18 (multi-stage precision filtration) in sequence, and is sterilized by the ultraviolet lamp tube 19 (≥100μW / cm² irradiation intensity) to ensure water quality.

[0067] When the liquid level in the filter box 16 exceeds the inlet of the siphon pipe 24, the siphon effect is triggered, and the liquid automatically flows into the storage tank 25. The balance pipe 20 and the sealing plug 21 regulate the air pressure to ensure the stability of the siphon.

[0068] The drive motor 38 (powered by the battery 7) rotates the drive rod 32, and the first blade 33 circulates the liquid in the water tank 25. The EPDM rubber water-cooling pipe 30 (resistant to 150℃) is tightly attached to the surface of the vibration damping box 5 to absorb heat and assist in vibration damping. The cooling air generator 28 (controlled by the temperature sensor 49) starts at high temperatures to enhance the cooling effect.

[0069] Driven by the magnetic coupling 43, the rotating rod 41 drives the second blade 42 to rotate, and external air enters the vibration damping box 5 through the vent pipe 44 (with a dust cover 45). The airflow is introduced into the evaporator box 11 through the ventilation pipe 46, and the oscillating plate 8 agitates the liquid to accelerate evaporation and improve heat dissipation efficiency.

[0070] Temperature sensor 49 monitors the internal temperature of vibration damping box 5 in real time, and control panel 48 dynamically adjusts the speed of drive motor 38 and the start / stop of cooling air generator 28. When pressure sensor 50 detects abnormal pressure in water storage tank 25, an alarm is triggered to ensure safe system operation.

[0071] In addition, the recovered vibration energy powers the drive motor 38, ultraviolet lamp 19, and air conditioning unit, reducing external energy consumption. Conical vibration damping blocks 4, sound-insulating foam 3, and non-contact magnetic transmission work together to reduce noise to below 40dB. Rainwater reuse and evaporative cooling reduce water consumption, achieving environmentally friendly operation.

[0072] This solution solves the problems of high energy consumption, reliance on external energy for heat dissipation, and incomplete vibration reduction of traditional transformers through the integrated design of vibration energy-electric energy conversion, rainwater purification and circulation, and multi-level vibration isolation and noise reduction, and achieves integrated control of "energy saving-noise reduction-efficient heat dissipation".

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
