Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment, in particular to a low-lying anti-waterlogging box-type transformer substation. Background Art

[0002] In the traditional box-type substation design, temperature control and water accumulation protection often have problems. High temperatures in summer can cause equipment to overheat, which may have an adverse effect on sensitive parts such as electronic components, reducing the operating life and stability of the substation. On the other hand, especially in low-lying areas, heavy rain may cause water to enter the substation and affect power equipment.

[0003] In the existing field of power equipment, especially in the design and construction of box-type substations, there are several key problems. Due to the lack of an efficient and reliable heat dissipation system, electrical equipment is likely to overheat when it is running continuously or under high load due to the large amount of heat generated. This will not only have a serious impact on the performance of the equipment and reduce operating efficiency, but also have a negative impact on the stability and life of the equipment.

[0004] Due to the lack of effective protection measures against water accumulation, the equipment may suffer from severe water erosion in heavy rain or high humidity environments. This may cause equipment failures such as short circuits, leakage, etc., making the equipment unable to operate normally, and may even cause permanent damage to the equipment.

[0041] Beneficial effects:

[0042] This solution uses a sealed box body to seal the bottom, which can effectively prevent the entry of external water. At the same time, the internal heat dissipation is achieved by drawing external air from a high position through the air inlet through the negative pressure environment of the ventilation base created by the air guide component. After the airflow enters, it cooperates with the evaporation of the hot air in the box to replace the cold air from bottom to top, and the internal hot air flow can be discharged through the heat dissipation holes. This air intake and heat dissipation method caters to the spontaneous flow direction of the hot air flow, so that it forms a better temperature control environment.

[0043] When the temperature is high in summer, when the outside airflow enters the ventilation base through the air inlet, it contacts the upper fins and then enters the box under the guidance of the air guide component. At the same time, the pump body starts, and it extracts the cool water buried underground in the hollow pile foundation through the pumping pipe, so that the water is pumped into the heat exchange base. Through the temperature conduction of the cooling component, the air temperature in the ventilation base is reduced, and then it enters the box for heat dissipation;

[0044] When exposed to high temperatures in the summer, the ceiling is heated greatly, causing it to conduct greater heat radiation inward. The heat radiation inward is then blocked by the heat radiation plate. At the same time, the heat radiation plate itself generates heat after blocking the heat radiation, causing the heat to be discharged through the guide holes. The heat is then mixed with the hot air flow in the box and discharged through the heat dissipation holes, which can reduce the impact of heat radiation in the box under exposure and cause local temperature rise.

DETAILED DESCRIPTION

[0056] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0057] like Figures 1 to 8 As shown, a low-lying anti-waterlogging box-type substation includes: a ventilation base 1;

[0058] The box body 3 is fixedly connected to the upper surface of the ventilation base 1 and is used for installing and placing electrical equipment;

[0059] The heat exchange base 2 is located on the lower surface of the ventilation base 1 and is fixedly connected to absorb the heat of the airflow in the ventilation base 1;

[0060] The air guide component 5 is fixed through the upper surface of the ventilation base 1 and is used to guide the flow of external air;

[0061] The cooling component 6 is fixed through the opposite surfaces of the ventilation base 1 and the heat exchange base 2 to balance the air flow temperature in the ventilation base 1;

[0062] The hollow pile foundation 8 is installed below the heat exchange base 2, and the hollow pile foundation 8 is buried underground and filled with water for cooling;

[0063] The pump body 11 is located in the hollow pile foundation 8 and immersed in the water body, and is used to guide the water body in the hollow pile foundation 8 into the heat exchange base 2 for circulation;

[0064] The ceiling 4 is located above the box body 3 and is used for sealing and protecting the top;

[0065] The partition edge strip 13 is disposed between the box body 3 and the ceiling 4 , and is fixedly connected to the upper surface of the box body 3 , and is used for overhead installation of the ceiling 4 .

[0066] The structural design between the ventilation base 1 and the box body 3 makes the substation have a certain waterproof performance. When encountering water accumulation problems caused by low-lying areas or heavy rain, the ventilation base 1 acts as a pad, and the height of the air inlet 12 is at a high position, which can effectively prevent the accumulated water from entering the box body 3. In addition, a partition strip 13 is provided between the box body 3 and the ceiling 4 so that the ceiling 4 can be in a holiday state to prevent rainwater from entering the box body 3 from the top. At the same time, the heat dissipation holes 14 on the surface of the partition strip 13 can discharge the internal hot air flow, achieving protection while ensuring the stable discharge of internal gas.

[0067] In the high temperature of summer, the ceiling 4 may generate a large amount of heat radiation that evaporates inward under direct sunlight. The heat radiation plate 15 can block the heat radiation and dissipate the heat after absorbing it, preventing the box 3 from causing local temperature rise. At the same time, the heat is discharged through the guide hole 16 to prevent the internal temperature of the box 3 from being too high.

[0068] The presence of the air guide assembly 5 can form a negative pressure environment in the ventilation base 1, attracting external airflow to enter from the air inlet 12, and then discharge it through the top heat dissipation hole 14 to achieve the purpose of heat dissipation. When the external air enters the ventilation base 1, it will enter the box body 3 and replace the hot air flow evaporating in the box body 3 to form an airflow from bottom to top, satisfying the natural law of hot air rising and enhancing the heat dissipation effect.

[0069] In hot weather, the pump body 11 starts to guide the cold water in the hollow pile foundation 8 located underground into the heat exchange base 2 through the pumping pipe 9. The water in the heat exchange base 2 contacts the lower fins 63 and conducts temperature through the partition plate 61. The upper fins 62 contact the air to reduce the air temperature. The cooled air enters the box body 3 for heat dissipation. The starting point of this design is to use the low humidity environment underground and the naturally formed low temperature in the hot summer to help reduce the temperature inside the substation.

[0070] In summer, the underground temperature is reduced by the heat exchange fins 18 , thereby lowering the temperature inside the hollow pile foundation 8 .

[0071] Meanwhile, in winter, during the startup process, the low-temperature air cools the water body, causing it to cold-pile the soil through the heat exchange fins 18 .

[0072] Specifically, Figure 6 As shown, the air guide assembly 5 includes a mounting base 51, which penetrates and is fixed on the upper surface of the inner wall of the ventilation base 1, and a plurality of vertical frames 52 are fixedly connected to the upper surface of the mounting base 51. A motor 53 is commonly fixed to the top of the plurality of vertical frames 52, and an output shaft of the motor 53 is fixedly connected to a fan blade 54. A protective net 55 is arranged above the fan blade 54, and the protective net 55 is fixedly connected to the surface of the vertical frame 52.

[0073] The wind guide assembly 5 of the device includes a mounting seat 51, which is fixed on the upper surface of the inner wall of the ventilation base 1. On the top of the mounting seat 51, a plurality of arranged vertical frames 52 can be seen, and a motor 53 is fixed on the top of these vertical frames 52. Fan blades 54 are fixed on the output shaft of the motor 53, and these fan blades 54 can be driven by the motor 53 to rotate to generate wind. Above the fan blades 54, the mounting seat 51 is provided with a protective net 55 to increase safety. This protective net 55 is fixedly connected to the surface of the vertical frame 52 to ensure its stability and prevent the lines from being dragged down and contacting the fan blades 54 to cause safety hazards.

[0074] The main function of the wind guide assembly 5 is to drive the air flow and provide the necessary fluidity for the air inside the box-type substation to improve the heat dissipation efficiency. Specifically, the motor 53 drives the fan blades 54 to rotate, generating wind force, attracting external air to enter, and forming airflow along the heat dissipation channel of the system. At the same time, the existence of the protective net 55 is to prevent dust and other impurities from entering with the wind, reducing the maintenance workload of the electrical equipment.

[0075] Specifically, Figure 3 and Figure 4 As shown, it also includes:

[0076] A plurality of adjacently arranged heat radiation panels 15;

[0077] Both sides of the heat radiation plate 15 are fixedly connected to the stepped inner wall of the partition edge strip 13;

[0078] The four sides of the partition edge strip 13 are provided with heat dissipation holes 14, and the two sides of the heat radiation plate 15 are provided with a plurality of guide holes 16;

[0079] The upper surface of the partition edge strip 13 is fitted and fixed to the inclined inner wall of the ceiling 4 , and the song list edge strip is located inside the ceiling 4 .

[0080] The basic function of the heat radiation plate 15 is to enhance the transfer and dispersion of heat in the substation through the heat dissipation holes 14 and the guide holes 16, thereby improving the heat dissipation efficiency.

[0081] Specifically, Figure 5 As shown, the lower surface of the heat exchange base 2 is fixedly connected with a fixing base 7, and a water pumping pipe 9 and a water return pipe 10 are arranged in the fixing base 7. The top ends of the water pumping pipe 9 and the water return pipe 10 are both penetrated and fixed on the inner walls of both sides of the heat exchange base 2;

[0082] The lower surface of the fixing seat 7 is fixedly connected to the upper surface of the hollow pile foundation 8 by bolts;

[0083] The water pumping pipe 9 and the water return pipe 10 are both connected to the hollow pile foundation 8 .

[0084] The pumping pipe 9 and the return pipe 10 set up in the heat exchange base 2 structure are mainly used to circulate the cooling water from the underground hollow pile foundation 8 to reduce the temperature inside the ventilation base 1 and improve the heat dissipation efficiency of the entire system.

[0085] Specifically, Figure 4 As shown, the box body 3 includes a bracket 31 fixed on the upper surface of the ventilation base 1, and three sides of the bracket 31 are provided with side panels 32 for sealing. The corresponding side of the bracket 31 is provided with a door panel 33, and the closed part of the door panel 33 and the side panel 32 is sealed;

[0086] The partition edge strip 13 is located on the upper surface of the bracket 31 and is fixedly connected.

[0087] The bracket 31, side panels 32 and door panels 33 in the box body 3 are designed to provide better sealing and protection for the equipment during operation, effectively preventing dust, water vapor and other factors that affect the operation of the equipment. In particular, the presence of the partition edge strip 13 makes the connection between the bracket 31 and the ceiling 4 tighter, further improving the sealing and protection of the box body 3.

[0088] Specifically, Figure 5 and Figure 8 As shown, the water outlet of the pump body 11 is connected to the bottom end of the water pumping pipe 9, and the arc-shaped side wall of the hollow pile foundation 8 is provided with a plurality of heat exchange fins 18.

[0089] The pump body 11 exists to cooperate with the water pumping pipe 9 to circulate cooling water, and the connection channel between the output port and the bottom of the water pumping pipe 9 can allow the cooling water to enter the ventilation base 1 for heat dissipation.

[0090] Specifically, Figure 8 As shown, the cooling assembly 6 includes a partition plate 61 that penetrates and is fixed between the ventilation base 1 and the heat exchange base 2, and the upper surface of the partition plate 61 is provided with upper fins 62 for contacting with the airflow;

[0091] The lower surface of the partition plate 61 is provided with lower fins 63 that come into contact with the water.

[0092] Specifically, Figure 3 As shown, two and / or more electrical racks 17 are symmetrically arranged in the box body 3 , and the electrical racks 17 are fixed on the surface of the corresponding side panels 32 .

[0093] The electrical rack 17 serves as the framework of the equipment inside the box 3 and can provide stable and reliable support for the electrical equipment inside the box 3, so that the equipment can operate in a safe and stable environment.

[0094] Specifically, Figure 1 As shown, air inlets 12 are fixed on both sides of the ventilation base 1, the air inlets 12 are connected to the inner wall of the ventilation base 1, and the top of the air inlet 12 is arranged in a barb shape.

[0095] The design of the air inlet 12 allows the outside air to enter the box body 3 more smoothly, providing the necessary cooling air for the electrical equipment and improving the heat dissipation efficiency. At the same time, the barbed hook design can prevent foreign matter such as rainwater from entering.

[0096] The box-type substation proposed in this scheme combines multiple designs such as water accumulation protection, active ventilation and heat dissipation, and temperature regulation. It has shown significant advantages in preventing external water from entering and promoting air flow to improve heat dissipation. Especially under high temperature conditions, underground low-temperature water can be used for heat exchange and cooling, as well as effectively resisting and discharging ceiling 4 heat radiation, thereby ensuring the stable operation and service life of the internal equipment of the substation. In general, this design improves the operating efficiency of the substation, ensures the stability of power supply, and also provides effective guarantees for the environmental adaptability and reliability of the substation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
