[0002] The oil-immersed transformer is a new type of high-performance transformer with more reasonable structure and better performance. The three core columns of the three-dimensional winding core are arranged in a regular triangle, and there is no air gap in the magnetic circuit. The winding is more compact, the lengths of the three magnetic circuits are consistent and the shortest, and the cross-sectional area of the core column is closer to a circle. Therefore, the performance is further improved, the loss is reduced, the noise is reduced, the three phases are balanced, and the third harmonic component is reduced.

[0003] The patent document with application number CN202223348724.4 discloses an energy-saving oil-immersed transformer, which comprises a filter screen, two mounting frames fixedly connected to the bottom end of the oil-immersed transformer body, and four heat dissipation fins fixedly connected to the four ends of the oil-immersed transformer body. The energy-saving oil-immersed transformer further comprises two annular heat pipes, two annular heat pipes are sleeved on the surface of the oil-immersed transformer body to dissipate heat from the oil-immersed transformer body, a top plate, four support columns are fixedly connected to the top end of the oil-immersed transformer body, and the top plate is fixedly connected to the top end of the four support columns. A water storage tank is fixedly connected to the inside of the top plate to receive rainwater to provide water source for the annular heat pipes.

The utility model uses natural rainwater as the water cooling medium and uses solar energy to provide power for the water cooling cycle, which is more environmentally friendly.

[0004] The structure uses rainwater to dissipate heat from the transformer by setting a rainwater collecting mechanism on the top of the transformer, but the filter plate on the top of the structure filters the rainwater. The filter plate is easy to block, and the temperature of the rainwater cannot reach the heat dissipation effect for a long time in daily use.

[0034] The cleaning assembly 8 comprises a mounting seat 801 which is slidingly connected to the top of the filter seat 701, a roller shaft 802 is rotatably connected to the mounting seat 801, a wind wheel 803 is fixedly installed on the other end of the roller shaft 802, a toothed plate 804 is fixedly connected to the top of the filter seat 701, a walking gear 805 is fixedly installed on the roller shaft 802, the walking gear 805 is located on the top of the toothed plate 804 and is engaged with the toothed plate 804, and uniformly distributed brush hairs 806 are installed on the roller shaft 802 and are located on the top of the filter screen plate 702.

[0035] The solar energy assembly 9 comprises a solar panel 901 and a storage battery 902, the solar panel 901 is fixedly installed on the top of the shielding cover 5, the storage battery 902 is installed on the bottom of the shielding cover 5, and the solar panel 901 and the storage battery 902 are electrically connected.

[0036] The filter screen plate 702 is made of metal material, the filter screen plate 702 is coated with hydrophilic paint, and a water filtering film is connected to the inner wall of the filter seat 701.

[0037] The oil immersed transformer body 1 is an outdoor transformer, the two side oil pipe bodies 2 are located in the inside of the heat shield 301, the temperature sensor 304 operates in real time to monitor the temperature of the oil pipe body 2, the processor 10 receives signals to judge whether the value is in the safe interval and higher than the interval value, the shielding cover 5 at the top cooperates with the extension plate 6 to shield the top of the oil immersed transformer body 1, thereby playing a protection role and also reducing the direct sunlight, reducing the temperature rising speed of the oil immersed transformer body 1 and improving the heat dissipation efficiency.

[0038] In the process of assembling the oil-immersed transformer body 1, the shielding cover 5 is installed on the top of the oil-immersed transformer body 1, so that the two groups of heat dissipation elbow pipes 708 in the rainwater heat dissipation system 7 are located on the front and back of the oil-immersed transformer body 1, respectively, thereby increasing the heat exchange area with the oil-immersed transformer body 1, and the user fills the cooling water into the inside of the filter seat 701 so that the liquid surface reaches the bottom of the filter screen plate 702.

[0039] In the process of operating the oil-immersed transformer body 1, the oil in the oil pipe flows, and the partial temperature sensor 304 inside the heat shield 301 monitors the temperature thereof. In the process of operation, heat is generated. The processor 10 controls the operation of the heat dissipation fan 303 and the semiconductor refrigeration sheet one 302, controls the power of the heat dissipation fan 303 and the semiconductor refrigeration sheet one 302 according to the received value, and the temperature of the refrigeration end of the semiconductor refrigeration sheet one 302 inside the heat shield 301 is reduced. The heat dissipation fan 303 starts to rotate and sends the bottom airflow into the inside of the heat shield 301. Since the airflow containing heat moves upward, the bottom airflow with low temperature enters the inside of the heat shield 301, so that the temperature is further reduced after passing through the refrigeration surface and continuously moves upward. The cold air passes through the bent oil pipe body 2 and is discharged through the top of the heat shield 301. The cold flow exchanges heat with the oil pipe body 2. The continuously flowing oil exchanges heat with the cold flow and returns to the inside of the oil-immersed transformer body 1, thereby achieving the effect of cooling. The processor 10 controls the power of the heat dissipation fan 303 and the semiconductor refrigeration sheet one 302 in real time according to the value returned by the temperature sensor 304, thereby achieving the effect of energy-saving and heat dissipation.

[0040] In the above process of exchanging heat with the oil pipe, the airflow continuously passes through the top of the heat shield 301 upward, and the impeller 402 in the bird repelling assembly 4 is located at the top of the heat shield 301. The airflow upwardly contacts the impeller 402, thereby pushing the impeller 402, so that the impeller 402 continuously rotates. The multiple groups of knocking blocks 403 connected to the impeller 402 start to rotate under the action of the rope. The moving knocking blocks 403 continuously impact the metal sheet 404, thereby emitting impact sound. The sound starts to spread to the surrounding space, thereby dispersing the birds near the oil-immersed transformer body 1.

[0041] In the operation process of the oil-immersed transformer body 1, heat is also emitted in front and back of the oil-immersed transformer body 1. At this time, the heat dissipation elbow pipe 708 is in front and back of the oil-immersed transformer body 1. Since the heat dissipation elbow pipe 708 is in a bent state, the heat exchange area with the oil-immersed transformer body 1 is improved. According to the adjustment of the semiconductor refrigeration piece two 705 to the corresponding power under the control of the processor 10, the water flow in the water collecting pipe 704 is refrigerated. Due to the fluidity of water, the temperature of the water flow in the heat dissipation elbow pipe 708 is synchronously reduced, thereby reducing the surface temperature of the heat dissipation elbow pipe 708. In the process of heat emission of the oil-immersed transformer body 1, heat is exchanged with the attached heat dissipation elbow pipe 708, thereby achieving the heat dissipation effect.

[0042] In the operation process, if the temperature is too low at night, the processor 10 controls the electrical appliance to be closed to achieve natural heat dissipation. If it is a rainy day, the processor 10 controls the electric control valve 706 to be opened. The electric control valve 706 is opened to discharge the water flow in the rainwater heat dissipation system through the water collecting pipe 704. Subsequently, the rainwater at the top enters the inside of the filter seat 701, penetrates through the filter screen plate 702, and then enters the inside of the heat dissipation elbow pipe 708 through the multiple groups of collecting pipes 703. As the rainwater continuously enters, the liquid level continuously rises. The impurities in the rainwater are blocked by the filter screen plate 702. The filter screen plate 702 is coated with a hydrophilic material, which can help water molecules to penetrate the filter screen plate 702 more easily, while reducing the residence time of water droplets on the surface to reduce evaporation. The filter membrane can filter and reduce evaporation. After the rainy weather ends, the rainwater stored in the rainwater heat dissipation system 7 is new collected cooling water. The cooling water does not need to be manually added and replaced.

[0043] In the operation process of the oil-immersed transformer body 1, since it is in the outdoor, it will be affected by the natural wind. The wind wheel 803 with a large stress area is moved by the wind force, thereby driving the roller shaft 802 to rotate. The roller shaft 802 and the mounting seat 801 are stably moved by cooperating with the walking gear 805 and the toothed plate 804. The continuously rotating brush 806 moves on the top of the filter screen plate 702, thereby cleaning the top of the filter screen plate 702. The dust and impurities attached to the filter screen plate 702 are separated, thereby reducing the possibility of clogging of the filter screen plate 702 under the action of the wind force, thereby improving the filtering effect and avoiding the impurities and foreign matters from entering the rainwater heat dissipation system 7 to affect the heat exchange effect.

[0044] The solar panel 901 on the top of the shielding cover 5 can absorb solar energy and convert it into electrical energy, which is stored in the storage battery 902 for power supply of the transformer and surrounding components.

[0045] In the application, by leading the oil pipe in the transformer to the inside of the two-side oil pipe heat dissipation system 3, cooperating with the temperature sensor 304, the power of the semiconductor refrigeration sheet 302 and the heat dissipation fan 303 can be automatically changed, the power is adjusted to the corresponding while realizing heat dissipation, thereby realizing intelligent adjustment of the heat dissipation effect, ensuring that enough heat dissipation is provided when needed and reducing energy consumption when the temperature is low, thereby realizing energy saving, the oil pipe penetrates the transformer body and forms a coil pipe, which can increase the contact area of the oil and the heat dissipation assembly and improve the heat exchange efficiency, the bird repelling assembly 4 arranged at the top is pushed by the airflow generated by heat dissipation and continuously generates sound to drive away birds nearby, which can prevent birds from nesting or staying near the transformer and reduce potential damage to the transformer, such as short circuit, insulation damage, etc., and the power of the bird repelling assembly 4 comes from the bottom heat dissipation airflow, which does not need external energy and is friendly to the environment.

[0046] The application can effectively reduce the direct sunlight on the surface of the transformer through the shielding cover 5, reduce the rising speed of the surface temperature and the internal oil temperature, thereby reducing the heat dissipation demand, and the heat exchange area with the transformer is increased by arranging the rainwater heat dissipation system 7 to realize heat dissipation, the rainwater collection system 7 can automatically discharge old rainwater and collect new rainwater when it rains, which can prevent impurities in the rainwater from depositing and microorganisms from growing, maintain the refrigeration effect, realize filtration of the rainwater during the rainwater collection process, cooperate with the hydrophilic material and the water filtration membrane to reduce water evaporation, the whole system utilizes natural rainwater and wind energy for heat dissipation, reduces the consumption of electricity and other resources, and meets the concept of energy saving and environmental protection.

[0047] The cleaning assembly 8 can automatically remove the impurities and deposits on the filter screen plate 702 by the cleaning brush pushed by the wind wheel 803, maintain the cleanliness of the filter screen plate 702, prevent clogging, the clean filter screen plate 702 can ensure that the rainwater flows into the heat dissipation elbow pipe 708 smoothly, improve the rainwater collection efficiency, thereby maintaining the effective operation of the heat dissipation system, reducing the need for manual maintenance, reducing the maintenance cost and frequency, preventing impurities from entering the inside of the rainwater, maintaining the cleanliness of the rainwater, improving the heat exchange efficiency with the heat dissipation elbow pipe 708, ensuring the heat dissipation effect, and the automatic cleaning mechanism can ensure that the system can maintain a good working state in the unattended condition, improve the reliability of the system, utilize natural wind energy for cleaning, do not need external energy, meet the concept of energy saving and environmental protection.

[0048] Please refer to Figure 1 and 4 Wherein: the both sides of the filter seat 701 are provided with through grooves 11, and the height of the filter screen plate 702 corresponds to the through grooves 11.

[0049] In the present invention, the opening of the through groove 11 makes the top of the filter plate 702 the same height as the inner bottom wall of the through groove 11, so that impurities and foreign matter attached to the top of the filter plate 702 can be quickly discharged through the setting of the through groove 11, preventing the filter plate 702 from being lower than the top of the filter seat 701, resulting in dust and foreign matter being unable to be discharged, causing blockage and affecting the filtering effect.

[0050] See also Figure 1 , wherein: the extension plate 6 is in an inclined state, and the top of the extension plate 6 is provided with evenly distributed confluence grooves.

[0051] In the present invention, when rainwater falls from the top to the top of the extension plate 6, the inclined extension plate 6 will guide the rainwater into the interior of the filter seat 701. At the same time, the confluence groove can make the rainwater converge to accelerate the flow rate, so that the rainwater quickly fills the interior of the rainwater heat dissipation system 7, thereby achieving rapid collection to prevent the rainfall from being too small, resulting in too little rainwater entering the rainwater heat dissipation system 7 and affecting the heat dissipation effect.

[0052] See also Figure 6 , wherein: a signal transceiver module 12 is integrated in the oil-immersed transformer body 1, and the signal transceiver module 12 is connected to the processor 10 by signal.

[0053] In the present invention, during the operation of the oil-immersed transformer, the signal transceiver module 12 will transmit the signal to the terminal in real time through the processor 10, so that the maintenance personnel can timely understand the status of the equipment, thereby facilitating timely inspection and maintenance of the equipment. For example, the temperature sensor 304 transmits in real time that the transformer is in a high temperature and the heat dissipation is not effective, so the maintenance personnel can carry out inspection and maintenance in time to avoid damage to the transformer caused by continuous high temperature. For example, the rainwater sensor 707 will also transmit a signal when it detects that rainwater has not been collected for a long time.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
