[0022] ​To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] like Figures 1-7 As shown, a smart substation with adjustable ventilation includes a housing 2, a base 1, a baffle 3, and a drive assembly 4. The housing 2 is fixedly connected to the upper end of the base 1. A partition 5 is provided between the housing 2 and the base 1. One side of the housing 2 is a door for entry and exit. Multiple louvered heat dissipation windows can be installed on the side of the housing 2. The heat dissipation windows that meet the design requirements have a high waterproof rating but poor ventilation and heat dissipation effect. Cable interfaces are reserved on the side of the base 1. All equipment required for the substation is installed on the partition 5. The partition 5 has a ventilation port 501 connecting the housing 2 and the base 1. The ventilation port 501 is equipped with... A mesh-structured cover 6 allows people to stand on it and prevents small animals from entering the enclosure 2 through the ventilation opening 501; its main function is rodent prevention. The base 1 has ventilation openings 101 on its side. The top ends of a baffle 3 are hinged to the ventilation openings 101. A drive assembly 4, a motor, is built into the base 1. The motor's output is connected to the baffle 3, allowing the baffle 3 to rotate and open / close the ventilation openings 101. The drive assembly 4 controls the opening degree of the baffle 3, thereby controlling the ventilation volume. External natural air enters the base 1 and passes through the ventilation opening 501. Ventilation 101 allows for air exchange with the air inside enclosure 2, limiting the air exchange rate and resulting in a more linear temperature change within enclosure 2. This prevents damage to the equipment from large, short-term temperature fluctuations in the environment. For example, in extremely cold regions, the temperature inside a substation needs to be maintained at 30-40℃. If ventilation 101 is opened significantly, the temperature inside the substation may drop sharply to below 10℃. This would weaken cables and insulators in the equipment, and transformers and circuit breakers would be prone to failure or malfunction due to thermal expansion. It could also increase the load on the power system, leading to equipment overload. This could lead to a power outage; the ventilation openings 101 and drive components 4 are in multiple sets and distributed in various directions of the base 1. By controlling different drive components 4, the opening and closing or opening degree of the baffles 3 inside different ventilation openings 101 can be controlled, thereby regulating the airflow and speed flowing below the air exchange port 501, thus realizing intelligent control of the ventilation level in the substation; the power equipment inside the enclosure 2 has a built-in temperature monitoring unit. By adjusting the working state of the drive components 4 according to the ambient temperature feedback from the temperature monitoring unit, the ambient temperature inside the enclosure 2 can be made more reasonable.

[0024] In the above embodiment, the baffle 3 outside can abut the top of the air vent 101, providing a limit for the maximum opening of the baffle 3. The outer side of the bottom of the baffle 3 is provided with a sealing strip 303, which can abut the outer side of the base 1, which can provide a limit for the baffle 3 when closing the air vent 101, and can improve the sealing when closing the air vent 101. The inner side of the baffle 3 is provided with a fan-shaped structure 301, which rotates around the hinge point, and the arc edge of the fan-shaped structure 301 is provided with a toothed structure 302, the output end of the driving assembly 4 is a gear 401, which is engaged with the toothed structure 302 to drive, which can provide more gears and more freely control the opening of the baffle 3, and can also provide rigid support force to ensure the position and state of the baffle 3 after adjustment. The central angle of the fan-shaped structure 301 is 90°, the upper end surface of the fan-shaped structure 301 can abut the top of the air vent 101 when the baffle 3 is closed, and the maximum opening of the baffle 3 is horizontally arranged when the baffle 3 is opened. External air can enter the base 1 without resistance.

[0025] The partition 5 is provided with a mounting groove 502 communicating the box 2 and the base 1, and a fan 7 with an output end upward is arranged in the mounting groove 502, and the fan 7 is aligned with the electrical equipment in the box 2, which can provide heat dissipation for the electrical equipment and promote air exchange between the upper and lower areas of the partition 5. The top of the box 2 is a stable triangular structure that can provide drainage function. The top of the box 2 is provided with an electronic wind vane 8, and the partition 5 is provided with a control assembly, and the electronic wind vane 8, the control assembly and the driving assembly 4 are electrically connected in sequence; the electronic wind vane 8 feeds back the wind direction signal collected to the control assembly, and according to the environmental temperature feedback by the temperature monitoring unit, the corresponding heat dissipation or heat preservation strategy is adopted; when heat dissipation is carried out, if rapid and large heat dissipation is not required, only the baffle 3 opposite to the wind direction can be opened, so that the temperature in the box 2 is adjusted at a lower air exchange rate.

[0026] The working mode of the utility model is described as follows:

[0027] According to the region where the transformer substation is installed, each conventional technical parameter is adjusted, such as less heat dissipation windows reserved on the side of the box 2 in high latitude areas to avoid the temperature of the electrical equipment being too low, and the base 1 of the transformer substation is appropriately increased in basin areas or cities with abundant rainfall to prevent water immersion. The base 1 of the transformer substation is manufactured by prefabricated steel structure, the ventilation opening 101 is arranged above the cable interface, the lower end of the ventilation opening 101 is left with a 50cm water immersion safety distance from the ground, the cable interface adopts IP68 protection level to prevent water seepage from causing short circuit or corrosion, and the long-term electrical performance and mechanical stability can be maintained under the condition of water immersion. When the transformer substation is normally operated, the electronic wind vane 8 and the temperature monitoring unit transmit the electrical signal to the control assembly in real time, the control assembly adjusts the opening of the baffle 3 according to the obtained temperature data, so as to adjust the heat preservation or heat dissipation state of the box 2; in a more intelligent way, the wind direction of the electronic wind vane 8 is combined to adjust the baffle 3 in each direction, the flow and speed of the natural wind entering the base 1 are adjusted by the wind direction, which is equivalent to improving the heat dissipation efficiency by using the natural environment.

[0028] The above embodiments are only used to illustrate the technical solutions of the utility model, but not limit them; although the utility model is described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments can be modified, or part or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
