Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformer substations, in particular to cooling equipment used in box-type transformer substations. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation, is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device, which are prefabricated indoor and outdoor compact distribution equipment arranged in one according to a certain wiring scheme, that is, the transformer step-down, low-voltage distribution and other functions are organically combined, and installed in a moisture-proof and rust-proof steel structure box, which is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after the civil substation. The box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution room and distribution station and becomes a new set of transformation and distribution equipment. The common box-type substation needs to bear huge loads during operation and is prone to generate a lot of heat. The accumulation of heat can easily lead to damage to the substation and reduce its service life.

[0003] For example, the patent with the national authorized patent announcement number CN213602266U discloses a cooling device for a box-type substation, which relates to the technical field of box-type substations. A cooling device for a box-type substation, comprising a main body protection frame, fan circulation mechanisms are installed on both sides of the outer end of the main body protection frame, and air holes are provided at the connection between the main body protection frame and the fan circulation mechanism, and the remaining frames in the main body protection frame except for the connection to the fan circulation mechanism are sealed, and a storage cavity is provided inside the main body protection frame, and a cavity is provided inside the fan circulation mechanism. The utility model can keep dry ice in a solid state at all times, thereby better cooling the inside of the storage cavity. At the same time, the positioning and adjustment mechanism arranged at the lower end of the storage cavity can be adapted to box-type substations of various sizes by matching with the movable baffle, thereby expanding its scope of application.

[0004] However, the above-mentioned cooling equipment for box-type substations does not have the functions of full coverage of wind directions and directional guidance for targeted heat dissipation and cooling in the process of heat dissipation of distribution equipment in the box-type substation. Without good full coverage of wind directions, the convection circulation of air inside the box-type substation will be affected. Normal air convection circulation helps to maintain uniform overall air temperature. Lack of this function will cause the temperature in some areas to be too high, which is not conducive to the heat dissipation of equipment. The lack of directional guidance design will cause hot spots to form inside high-heat equipment, that is, some areas with higher local temperatures. The accumulation of these hot spots will accelerate the aging of equipment components and affect the reliability and stability of the equipment. Utility Model Content

[0011] The ventilation pipe is curved and covers the power distribution equipment in the box-type substation body through a transverse wind nozzle.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. Through the design of vents, air supply mechanisms and wind flow guide mechanisms, when dissipating heat for the power distribution equipment in the box-type substation body, the air supply mechanism can be started, and the air outlet of the air supply mechanism is covered directly above the power distribution equipment, so that the power distribution equipment below can be fully supplied with air for heat dissipation, so that the cold air can be directly delivered to the surface of the equipment to effectively take away the heat generated by the equipment. This method can significantly improve the heat dissipation efficiency, keep the equipment within the appropriate operating temperature range, and prevent certain parts from forming hot spots due to poor heat dissipation. It can reduce the impact of excessive local temperature on equipment performance and life, extend the service life of the equipment, and form a top-down air flow pattern by supplying air from above the equipment, promote air circulation inside the box-type substation body, and replace hot air with cold air and discharge it to the vents at the lower end, which helps to form good convection and further improve the overall heat dissipation effect;

This effect is due to the reduction of the airflow speed in the ventilation duct, causing the airflow to swirl and accumulate at the transverse air nozzle, thereby increasing the cooling area and contact time, thereby reducing the temperature of the blown air and facilitating heat dissipation. In addition, the swirling and accumulated airflow will increase the local air temperature, thereby improving the air's heat absorption capacity, which is beneficial to reducing the overall air temperature.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0031] like Figure 1-Figure 2 As shown, a cooling device for a box-type substation comprises: a box-type substation body 1, a top cover 2 is fixedly mounted on the upper surface of the box-type substation body 1, mounting plates 201 are fixedly mounted on both sides of the top cover 2, an air supply mechanism 3 is fixedly mounted on the lower surface of the mounting plate 201, and an air supply part of the air supply mechanism 3 passes through from one end of the top cover 2 to the inside of the top cover 2 and is flush with the power distribution equipment in the box-type substation body 1;

[0032] Among them, a wind flow guide mechanism 4 is rotatably installed in the top cover 2, and the wind flow guide mechanism 4 is located directly below the air outlet of the air supply mechanism 3 and is flush with it. The control end of the wind flow guide mechanism 4 extends from one side of the top cover 2 to one end of the outer surface of the top cover 2.

[0033] A ventilating opening 101 is provided on the outer surface of the box-type substation body 1 .

[0034] Through the design of the vents 101, the air supply mechanism 3 and the wind flow guide mechanism 4, when the power distribution equipment in the box-type substation body 1 is cooled, the air supply mechanism 3 can be started, and the air outlet of the air supply mechanism 3 is covered directly above the power distribution equipment, so that the power distribution equipment below can be fully cooled by air supply, so that the cold air can be directly delivered to the surface of the equipment to effectively take away the heat generated by the equipment. This method can significantly improve the heat dissipation efficiency, keep the equipment within a suitable operating temperature range, and prevent certain parts from forming hot spots due to poor heat dissipation, which can reduce the impact of excessive local temperature on equipment performance and life, and extend the service life of the equipment. By supplying air from above the equipment, a top-down air flow pattern can be formed, which promotes air circulation inside the box-type substation body 1, and hot air is replaced by cold air and discharged to the vents 101 at the lower end, which helps to form good convection and further improve the overall heat dissipation effect.

[0035] In the process of air supply and heat dissipation for the power distribution equipment, the staff can also rotate the wind flow guide mechanism 4 to the position specified by the staff, and then guide the wind blown out by the air supply mechanism 3 to the specified position to achieve the purpose of fixed-point air supply and heat dissipation, such as areas with concentrated hot spots. This precise guidance can ensure that the heat is taken away quickly and effectively, thereby improving the heat dissipation efficiency. Fixed-point air supply and heat dissipation can also avoid unnecessary waste of air flow, effectively concentrate the cold air on the parts of the equipment that need to be cooled, avoid ineffective waste of air flow, thereby saving energy and reducing operating costs, and then it can flexibly adjust the direction and angle of the air supply according to actual needs, adapt to the heat dissipation requirements under different equipment layouts and working conditions, and improve the adaptability of the system and the flexibility of operation.

[0036] like Figure 3-Figure 5 As shown, the air supply mechanism 3 includes a blower 301, which is fixedly mounted on the lower surface of the mounting plate 201, an air outlet of the blower 301 penetrates into the top cover 2 and is fixedly mounted with a ventilation pipe 302, and a horizontal air nozzle 303 is fixedly mounted on the lower end of the outer surface of the ventilation pipe 302;

[0037] The ventilation pipe 302 is curved and covers the power distribution equipment in the box-type substation body 1 through the transverse air nozzle 303 .

[0038] The diameter of the ventilation pipe 302 is larger than the diameter of the air outlet of the transverse air nozzle 303. The diameter of the ventilation pipe 302 is larger, while the air outlet of the transverse air nozzle 303 is smaller, thereby forming a fan casing effect to reduce the temperature of the blown air.

[0039] Through the design of the blower 301, the ventilation pipe 302 and the transverse wind nozzle 303, when the blower 301 is started to supply air to the ventilation pipe 302, the ventilation pipe 302 will blow the wind from top to bottom on the distribution equipment through the transverse wind nozzle 303 below, and in the process of the wind being blown out from the transverse wind nozzle 303, due to the larger diameter of the ventilation pipe 302 and the smaller air outlet of the transverse wind nozzle 303, a fan casing effect will be formed. This effect is due to the reduction of the wind speed in the ventilation pipe 302, which causes the airflow to swirl and accumulate at the transverse wind nozzle 303, thereby increasing the cooling area and contact time, thereby reducing the temperature of the blown air and facilitating heat dissipation. In addition, the swirling and accumulated airflow will increase the local air temperature, thereby improving the heat absorption capacity of the air, which is beneficial to reducing the overall air temperature.

[0040] like Figure 6 As shown, the airflow guide mechanism 4 includes a connecting rod 401, which is rotatably mounted between the two inner walls of the top cover 2, and a guide plate 402 is fixedly mounted on the middle part of the connecting rod 401. The guide plate 402 is suspended directly below the horizontal air nozzle 303 through the connecting rod 401;

[0041] The other end of the connecting rod 401 passes through from the inside of the top cover 2 to the outside and is fixedly mounted with a hand wheel 403 , so that the hand wheel 403 rotates in a damping manner on one side of the outer surface of the top cover 2 .

[0042] The outer surface of the hand wheel 403 is provided with a plurality of limit openings 407, into which the limit openings 407 can be inserted. The limit rod 406 is slidably installed in the limit ring 405 and the storage tube 404. The limit ring 405 and the storage tube 404 are fixedly installed at one end of the top cover 2, and a convex tooth is fixedly installed at one end of the limit rod 406.

[0043] A sliding column is fixedly installed in the storage tube 404, and the sliding column in the storage tube 404 slides into the limiting rod 406. A spring 408 is mounted on the outer surface of the sliding column of the storage tube 404, and both ends of the spring 408 respectively touch between the upper surface of the storage tube 404 and the upper surface of the limiting rod 406.

[0044] Through the design of connecting rod 401, guide plate 402, hand wheel 403, storage tube 404, limit rod 406, spring 408 and limit opening 407, in the process of supplying air and cooling the power distribution equipment, the staff can also lift the limit rod 406 from the limit opening 407 of the hand wheel 403 by pressing on the convex teeth on one side of the limit rod 406, and at the same time, the limit rod 406 will slide into the storage tube 404 and press on one end of the spring 408, and then the staff can rotate the hand wheel 403 to drive the guide plate 402 to rotate until it rotates to the worker. After reaching the designated position, the limit rod 406 can be released, and the limit rod 406 will be inserted into the limit opening 407 close to the hand wheel 403 again through the elastic force applied by the spring 408, so that a rotation limit effect can be applied to the hand wheel 403, so that the guide plate 402 can be fixed in the adjusted position, and the inclined guide plate 402 can guide the wind blown out of the horizontal wind nozzle 303 to the designated position to achieve the purpose of fixed-point air supply and heat dissipation, such as the area where hot spots are concentrated. This precise guidance can ensure that the heat is taken away quickly and effectively, thereby improving the heat dissipation efficiency.

[0045] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the power distribution equipment in the box-type substation body 1 is cooled, the blower 301 can be started to supply air to the ventilation pipe 302. The ventilation pipe 302 will blow the wind from top to bottom on the power distribution equipment through the horizontal wind nozzle 303 below. In the process of the wind blowing out of the horizontal wind nozzle 303, due to the large diameter of the ventilation pipe 302 and the small air outlet of the horizontal wind nozzle 303, it will form a fan casing effect. This effect is due to the reduction of the wind speed in the ventilation pipe 302, which causes the airflow to swirl and accumulate at the horizontal wind nozzle 303, thereby increasing the cooling area and contact time, thereby reducing the temperature of the blown air and facilitating heat dissipation. By supplying air from the top of the equipment, a top-down air flow pattern can be formed, and the hot air is replaced by cold air and discharged to the ventilation port 101 at the lower end, forming a good convection, further improving the overall heat dissipation effect, and for the power distribution equipment During the air supply and heat dissipation process, the staff can also lift the limit rod 406 from the limit opening 407 of the hand wheel 403 by pressing on the convex tooth on one side of the limit rod 406, and at the same time, the limit rod 406 will slide into the storage tube 404 and press on one end of the spring 408, and then the staff can rotate the hand wheel 403 to drive the guide plate 402 to rotate. After it rotates to the specified position of the staff, the limit rod 406 can be released, and the limit rod 406 will be inserted into the limit opening 407 close to the hand wheel 403 again through the elastic force applied by the spring 408, and then a rotation limit effect can be applied to the hand wheel 403, so that the guide plate 402 can be fixed in the adjusted position, and the inclined guide plate 402 can guide the wind blown out of the horizontal wind nozzle 303 to the specified position to achieve the purpose of fixed-point air supply and heat dissipation, such as the area where hot spots are concentrated. This precise guidance can ensure that the heat is taken away quickly and effectively, thereby improving the heat dissipation efficiency.

[0046] In summary: the cooling equipment used in the box-type substation has a full range of air supply and heat dissipation operations for the distribution equipment. It can directly deliver cold air to the surface of the equipment and effectively take away the heat generated by the equipment. This method can significantly improve the heat dissipation efficiency, keep the equipment within a suitable operating temperature range, and prevent certain parts from forming hot spots due to poor heat dissipation. It can reduce the impact of local high temperature on equipment performance and life, extend the service life of the equipment, and also has the purpose of guiding the blown wind to the designated position to form fixed-point air supply and heat dissipation, such as areas where hot spots are concentrated. This precise guidance can ensure that the heat is taken away quickly and effectively, thereby improving the heat dissipation efficiency. Fixed-point air supply and heat dissipation can also avoid unnecessary waste of wind flow, effectively concentrate cold air on the equipment parts that need to be cooled, avoid ineffective waste of wind flow, thereby saving energy and reducing operating costs.
