Description

Technical Field

[0001] The present invention relates to the technical field of substations, and in particular to a box-type substation with an efficient and reliable heat dissipation system. Background Art

[0002] Box-type substations have replaced existing civil power distribution rooms and substations, becoming a new type of complete power distribution device. They are suitable for residential areas, urban utilities, bustling downtown areas, construction power supplies, mines, factories and enterprises, oil and gas fields, and wind power stations. Users can choose a box-type substation based on different usage conditions and load levels. As electricity demand continues to grow, the power density of electrical equipment within box-type substations continues to increase, and the heat generated during operation has also increased significantly.

[0003] At present, the commonly used heat dissipation methods for box-type substations include natural ventilation, mechanical ventilation, and convection heat exchange. Natural ventilation heat dissipation relies on the heat dissipation vents on the side of the box. Affected by the layout of the cabinets inside the box, the airflow is not smooth and the heat dissipation efficiency is low. Although mechanical ventilation uses fans to enhance air exchange, the fan power is limited and it is easy to introduce dust and moisture, affecting equipment performance.

[0041] It should be noted that when the transformer 29 is heat-dissipating, fresh air is sent into the air guide grooves 13 inside the two air guide frames 11 through the air intake pumps 10 on both sides, and the double pulley 20 is controlled to rotate by the output shaft of the driving servo motor 19. The double pulley 20 and two belts are used in conjunction with the two pulleys 18 to drive the lowest blowing wheel 16 inside the air guide frames 11 on both sides to rotate. At the same time, the several blowing wheels 16 inside the air guide groove 13 use the transmission cooperation between the sprocket 17 and the chain to allow the upper several blowing wheels 16 to rotate synchronously with the lowest blowing wheel 16. During the rotation of the blowing wheel 16, the fresh air inside the air guide groove 13 is sent out through the blowing slots 15 on both sides and the blowing port 12 on one side of the air guide frame 11.

Several heat dissipation fins 25 are made of shape memory polymer material. Each fin unit is equipped with a micro sensor and a driver. When the temperature of the transformer box 1 rises, the sensor triggers the driver to automatically expand the heat dissipation fins 25 from a compact state to increase the heat dissipation area; after the temperature drops, the heat dissipation fins 25 return to their original state to reduce space occupancy. In addition, the surface of the heat dissipation fins 25 is designed with a dynamic texture, which changes the surface roughness and airflow characteristics during the expansion process, further enhancing the convective heat transfer effect and achieving an optimal balance between heat dissipation performance and space utilization; in addition, several heat dissipation fins 25 are also provided inside the heat dissipation partition 21 and on the back of the inner wall of the transformer box 1.

[0045] Furthermore, heat dissipation plates 22 are fixedly provided on both sides of the interior of the heat dissipation top frame 3, and heat dissipation channels 28 are provided inside the two heat dissipation plates 22.

[0046] It should be noted that when the interior of the transformer box 1 is subjected to heat dissipation treatment, the hot air inside the transformer box 1 is discharged to the outside through the heat dissipation fan 23, and the discharged hot air is sent out through the heat dissipation flow channel 28 inside the heat dissipation plates 22 on both sides. At the same time, the heat exchange tube 24 and several heat dissipation fins 25 inside the transformer box 1 are used to absorb the heat energy generated by the transformer 29 inside the transformer box 1, and the heat exchange medium flowing inside the heat exchange tube 24 circulates through the two oil exchange interfaces 27. The heat energy inside the transformer box 1 is efficiently exchanged through the heat exchange medium, and the absorbed heat is centrally recovered and reused, which greatly improves the utilization rate of the heat inside the transformer box 1.

It can automatically expand or restore to its original shape according to the temperature, optimizing the heat dissipation performance and space utilization, and the dynamic texture on its surface further enhances the convective heat transfer effect; in addition, heat dissipation fins 25 are also provided on the back of the heat dissipation partition 21 and the inner wall of the transformer box 1, further improving the overall heat dissipation capacity, ensuring the stable operation of the equipment inside the transformer box 1, effectively reducing the temperature, and improving the reliability and service life of the equipment.

[0048] Example 5

[0049] Specifically, this embodiment also discloses a heat dissipation method for a box-type substation with an efficient and reliable heat dissipation system, including the following steps:

[0050] Step 1: Start the air intake pumps 10 on both sides of the fixed base 2. The outside air is first coarsely filtered through the air intake grille 7 to block large particles of impurities; then the dust particles are further filtered through the air intake filter 6. At the same time, the scraper frame 8, driven by the motor, uses a cleaning brush to clean the dust on the surface of the air intake filter 6 to ensure smooth ventilation of the filter. Subsequently, the air enters the adsorption filter frame 5 filled with activated carbon adsorption particles to absorb the remaining dust and harmful gases. Finally, the clean air is sent by the air intake pump 10 through the duct to the blowing component in the transformer box 1;

[0051] Step 2: The servo motor 19 is driven to start, and its output shaft drives the double pulley 20 to rotate. The transmission of the belt and the pulley 18 rotates the lowermost blowing wheel 16 in the air guide frame 11 on both sides. Then, with the help of the sprocket 17 and the chain, the multiple blowing wheels 16 in the air guide groove 13 are driven to rotate synchronously. The rotating blowing wheels 16 blow the fresh air in the air guide groove 13 evenly to the surface of the transformer 29 through the blowing groove 15 and the blowing port 12. By adjusting the speed of the driving servo motor 19, the blowing intensity can be flexibly controlled to achieve efficient heat dissipation.

[0052] Step 3: The heat dissipation fan 23 discharges the heated air in the transformer box 1 upward, and the hot air is sent out through the "Z"-shaped heat dissipation channel 28 in the heat dissipation plate 22 to enhance the heat dissipation effect. At the same time, the heat exchange tube 24 and the heat dissipation fin 25 play a role. When the temperature of the transformer box 1 rises, the heat dissipation fin 25 made of shape memory polymer material automatically unfolds to increase the heat dissipation area. The dynamic texture on its surface enhances convective heat transfer. The heat exchange medium in the heat exchange tube 24 circulates through the oil exchange interface 27 to absorb the heat generated by the transformer 29, realizing centralized recovery and reuse of heat energy.
