[0002] An energy storage power station is a facility that stores and releases electrical energy through the conversion of electrical energy into other forms of energy. In an energy storage power station, the dry-type transformer, as a crucial piece of electrical equipment, plays a key role in voltage transformation and power transmission. During operation, existing dry-type transformers in energy storage power stations generate a significant amount of heat due to their own losses. If this heat cannot be dissipated in time, the internal temperature of the transformer will rise, affecting its operating efficiency and lifespan. Current methods to address heat dissipation include adding heat sinks or installing fans. However, while these methods improve heat dissipation, they also increase energy consumption and offer limited improvement in heat dissipation efficiency, failing to meet the energy-saving and high-efficiency heat dissipation requirements of energy storage power stations for dry-type transformers.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1 and Figure 2As shown, this embodiment provides an energy-saving dry-type transformer for an energy storage power station, including a transformer body 1. Multiple heat dissipation fins 11 are evenly spaced on the sidewalls of the transformer body 1. These heat dissipation fins 11 are made of a metal material with high thermal conductivity, which increases the contact area between the transformer body 1 and the air, facilitating natural heat dissipation. A mounting frame 2 is provided on the top of the transformer body 1, and a solar panel 3 and a heat dissipation assembly 5 are fixed on the mounting frame 2. The solar panel 3 is electrically connected to a battery 4. Under sunlight, the solar panel 3 can convert light energy into electrical energy and store it in the battery 4. The heat dissipation assembly 5 includes a heat dissipation box 51, which is made of a material with good heat insulation performance. An air inlet 511 is provided on the top of the heat dissipation box 51, and a fan 52 is installed at the air inlet 511. Multiple air outlets 512 are opened on the side of the heat dissipation box 51 near the transformer body 1 to ensure that air is blown towards the transformer body 1. Furthermore, the transformer... A temperature sensor 6 is also installed on the transformer body 1, which can monitor the temperature of the transformer body 1 in real time and transmit the temperature signal to the controller. The controller is electrically connected to the fan 52. When the temperature of the transformer body 1 is lower than the set threshold, the controller controls the fan 52 to stop. At this time, the heat dissipation is mainly achieved by natural convection of the heat dissipation fins 11. When the temperature rises and reaches the set threshold, the controller controls the fan 52 to start. The fan 52 draws air in from the air inlet 511, passes through the heat dissipation box 51, and blows it out from the air outlet 512, thereby forcibly dissipating heat from the transformer body 1 and improving the heat dissipation efficiency. At the same time, the battery 4 is electrically connected to the fan 52, the temperature sensor 6, and the controller, and uses clean solar energy to power it, thereby reducing the operating energy consumption of the equipment and achieving the purpose of energy saving. The temperature sensor 6 can intelligently adjust the operating status of the fan 52 according to the actual temperature of the transformer body 1, which can avoid the ineffective operation of the fan 52 and further improve the energy saving effect.

[0021] like Figure 2As shown, the heat sink 51 is equipped with multiple spaced-apart guide plates 53, forming a guide channel 54 between adjacent guide plates 53. One end of the guide channel 54 is connected to the air outlet of the fan 52, and the other end faces the transformer body 1. The guide plates 53 guide the airflow blown by the fan 52 to flow evenly and orderly, avoiding turbulence in the airflow within the heat sink 51. A thermoelectric cooler 55 is installed inside the heat sink 51, with the cold end of the thermoelectric cooler 55 facing the inside of the heat sink 51 to ensure that it can absorb the heat of the air flowing through the heat sink 51, while the hot end is located on the outside of the heat sink 51. The semiconductor cooling chip 55 is electrically connected to the battery 4 and the controller, and is powered by the battery 4 and controlled by the controller. When the temperature detected by the temperature sensor 6 continues to rise and reaches a higher secondary threshold, the controller starts the semiconductor cooling chip 55 while keeping the fan 52 running. The cold end of the semiconductor cooling chip 55 quickly reduces the temperature of the air in the heat dissipation box 51. Under the action of the fan 52, the cold air is blown out from the air outlet 512 through the guide channel 54 and exchanges heat with the surface of the transformer body 1, further enhancing the heat dissipation effect.

[0022] Preferably, the guide plate 53 is arc-shaped, and the arc directions of adjacent guide plates 53 are opposite. When the fan 52 blows airflow into the heat sink 51, the airflow first contacts the arc-shaped surface of the first guide plate 53. Under the guidance of the surface, the airflow flows smoothly along the arc direction, and then enters the next section of the guide channel 54 formed by the reverse arc-shaped guide plates 53, where the airflow direction is guided and changed again. This process is repeated, and under the action of the guide plate 53, the airflow forms an orderly and uniformly diffused flow path in the heat sink 51, which increases the residence time of the airflow in the heat sink 51, thereby prolonging the heat exchange time between the airflow and the air in the heat sink 51 and the cold end of the semiconductor cooling chip 55, and improving the heat exchange efficiency.

[0023] Furthermore, the air outlet 512 of the heat sink 51 is equipped with an airflow adjustment component 56, such as... Figure 3 As shown, the airflow adjustment component 56 includes several rotatable blades 561, which are driven by a motor 562. The motor 562 is electrically connected to the battery 4 and the controller, and is powered by the battery 4 and controlled by the controller. Multiple temperature sensors 6 are set and distributed in different parts of the transformer body 1. When there is a temperature difference in different parts of the transformer body 1, the temperature sensors 6 feed back the temperature information to the controller. The controller controls the motor 562 to rotate, which drives the blades 561 to rotate, thereby adjusting the direction of the airflow from the air outlet 512, so that the cold air can be blown more accurately to the higher temperature parts, achieving more efficient heat dissipation.

[0024] Mounting bracket 2 is used to support and adjust solar panel 3, including a bearing part 21, a support part 22, and an angle adjustment component 23. The bearing part 21 is made of high-strength material and has multiple mounting holes evenly distributed on it. The position and size of the mounting holes are perfectly matched with the fixing holes of the solar panel 3. The solar panel 3 is firmly fixed to the upper surface of the bearing part 21 by the fixing component, ensuring that the solar panel 3 will not loosen or shift under various working conditions. The support part 22 is also made of high-strength material and is fixed to the top of the transformer body 1. The angle adjustment component 23 is located between the support part 22 and the bearing part 21 and is provided with a horizontal adjustment part 231 and a tilt adjustment part 232, which are perpendicular to each other and are electrically connected to the battery 4 and the controller. The controller controls the horizontal adjustment part 231 and the tilt adjustment part 232 to work according to the data of the external light intensity sensor, so that the solar panel 3 always receives sunlight at the optimal angle, improves the conversion efficiency of solar energy, and thus provides more power for the heat dissipation system.

[0025] Preferably, the heat dissipation fins 11 are wavy. The wavy structure further increases the contact area between the heat dissipation fins 11 and the air, and at the same time, it can change the air flow path on the surface of the heat dissipation fins 11, enhance air turbulence, and improve the heat dissipation effect. The surface of the heat dissipation fins 11 is provided with a heat dissipation coating, which can improve the heat dissipation efficiency of the object through various means such as enhancing heat radiation and accelerating heat conduction, thereby further improving the heat dissipation efficiency.

[0026] A filter unit 57 is also installed at the preferred air inlet 511, such as Figure 4 As shown, the filter unit 57 includes several filters 571. A filter mounting groove 572 is provided at the air inlet 511. The filters 571 are fixed in the mounting groove 572 by a detachable structure 573. The filters 571 can filter dust, impurities and other substances in the outside air, preventing these substances from entering the heat dissipation box 51 and the transformer body 1, thus affecting the normal operation and heat dissipation effect of the equipment. The detachable structure 573 facilitates the installation and removal of the filters 571, and makes it convenient to clean and replace the filters 571.

[0027] The preferred controller is also connected to a wireless communication module; the wireless communication module can use wireless communication technologies such as Bluetooth, WiFi, 4G / 5G. Through the wireless communication module, staff can remotely obtain data such as temperature information and equipment operating status of the dry-type transformer, and can also remotely control the working status of equipment such as fan 52, semiconductor cooling chip 55, and motor 562, so as to realize remote monitoring and management of the dry-type transformer and improve the operation and maintenance efficiency of the equipment.
