Description

Technical Field

[0001] This utility model relates to the field of prefabricated transformer technology, and more specifically, to a prefabricated substation top-outlet heat dissipation component. Background Technology

[0002] The top-mounted ventilation and heat dissipation assembly of the prefabricated substation is an important component for achieving top ventilation and heat dissipation in prefabricated substations. During operation, electrical equipment such as transformers and switches in the prefabricated substation generate a lot of heat. By using the top-mounted ventilation and heat dissipation assembly to exhaust hot air to the outside of the substation and introduce cool air for circulation, the internal temperature of the substation can be effectively reduced, ensuring that the electrical equipment operates within the normal temperature range and improving the performance and service life of the equipment.

[0003] However, existing prefabricated substations mainly use upper and lower ventilation hoods for heat dissipation. This heat dissipation structure requires maintenance inside the substation and necessitates a power outage for maintenance, which can easily disrupt the normal operation of the substation. Furthermore, the installation cost of the upper and lower ventilation hood structure is high, and maintenance also increases operating costs. Moreover, when using existing prefabricated substation top-outlet cooling components, especially in desert or snowy areas, sand or snow can easily flow back into the substation, causing malfunctions. Therefore, it is necessary to address these issues. Utility Model Content

[0040] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0041] like Figures 1 to 7 As shown, a prefabricated substation top-outlet heat dissipation assembly includes:

[0042] The box frame 1 has a cover plate 2 fixedly installed at its upper end, and air outlets are provided on both side walls of the box frame 1; the lower end face of the box frame 1 is provided with an air inlet that communicates with the transformer.

[0043] Fan 3 is fixedly placed inside the frame 1. Fan 3 introduces airflow through the air inlet and discharges airflow through the air outlet.

[0044] The louver 4 is fixedly placed at the air outlet to prevent backdraft at the air outlet;

[0045] Air guide 5, the air inlet end of the air guide 5 is connected to the air outlet, and the air outlet end of the air guide 5 is arranged at an angle downward.

[0046] In this specific application, the top-discharge cooling assembly is fixed at the top of the substation. The fan 3 is started, and the fan 3 draws air from the substation through the air inlet of the frame 1, so that the heat generated by the transformer in the substation enters the fan 3 with the airflow. The fan 3 then discharges the heated airflow through the air outlet. The top-discharge cooling assembly is arranged at the top of the substation and can be removed for maintenance without interrupting power, improving the convenience of maintenance and ensuring the operating efficiency of the substation. The top-discharge cooling assembly has a simple structure and can effectively reduce product costs and operating costs.

[0047] The louver 4 can prevent backwind. By using the louver 4 and the air guide 5 together, it can effectively prevent dust, mud or rain and snow from flowing back into the air outlet, reduce the failure rate of the substation, and effectively adapt to the harsh environment of desert, heavy snow and other areas.

[0048] In the above embodiment, multiple fans 3 are provided, and the multiple fans 3 are arranged and fixedly placed in the frame 1 at equal intervals. A partition 6 is provided between two adjacent fans 3, and the partition 6 is fixedly connected to the inner wall of the frame 1.

[0049] In practical applications, by arranging multiple fans 3 inside the frame 1, the exhaust intensity can be increased, which can effectively improve the heat dissipation efficiency of the substation and enhance the heat dissipation effect.

[0050] In the above embodiments, a bracket 7 is provided inside the housing 1 corresponding to each of the fans 3, and the bracket 7 is fixedly connected to the housing 1; the fans 3 are placed inside the bracket 7, and the fans 3 are fixedly connected to the bracket 7.

[0051] In practical applications, a support 7 is arranged at each wind turbine 3 to stabilize the wind turbine 3 and reduce the damage to the substation caused by the vibration generated during the operation of the wind turbine 3.

[0052] In the above embodiments, the venetian blind 4 includes:

[0053] Window 401, which is fixedly placed at the air outlet of the box frame 1;

[0054] Multiple blades 402 are arranged sequentially from top to bottom within the window 401, and both ends of each blade 402 are rotatably connected to the window 401; each blade 402 is provided with a connecting frame 403.

[0055] A connecting rod 404 is placed on one side of the plurality of blades 402. The connecting rod 404 is rotatably connected to the plurality of connecting frames 403. The connecting rod 404 drives the plurality of blades 402 to be in a normally closed state through the plurality of connecting frames 403.

[0056] In practical applications, when the fan 3 is not running, the multiple blades 402 are normally closed under their own weight and the weight of the connecting rod 404. When the fan 3 is running, the airflow is generated and flows towards the louvers 4. The multiple blades 402 are subjected to the force of the airflow and deflected by the weight of the multiple blades 402 and the connecting rod 404. The louvers 4 are opened and the airflow is discharged through the air guide 5. When the external airflow flows back, the airflow flows upward at an angle through the air guide 5. The airflow acts on the multiple blades 402, and the multiple blades 402 are subjected to an upward force. Under the action of the upward force, the multiple blades 402 are more firmly closed, which can effectively prevent the airflow from flowing back into the box frame 1. This can also prevent dust, mud, or rain and snow from flowing back into the air outlet, reduce the failure rate of the substation, and effectively adapt to the harsh environment of desert, heavy snow and other areas.

[0057] In the above embodiments, the blade 402 includes:

[0058] Straight plate portion 4021, wherein the straight plate portion 4021 is arranged vertically;

[0059] Arc-shaped portion 4022, which is fixedly placed at the upper end of straight plate portion 4021;

[0060] The bending portion 4023 is fixedly placed at the lower end of the straight plate portion 4021, and the bending portion 4023 is close to the plate surface of the straight plate portion 4021 of the next blade 402 under the action of gravity.

[0061] In practical applications, the bent portion 4023 is partially stacked on the surface of the straight plate portion 4021 of the next blade 402. When subjected to an upward inclined force, the bent portion 4023 can block the airflow flowing to the arc-shaped portion 4022 of the next blade 402, preventing the arc-shaped portion 4022 from being subjected to the force of the airflow, thereby preventing the blade 402 from deflecting. When the bent portion 4023 is subjected to the force of the airflow, it is in close contact with the straight plate portion 4021 of the next blade 402, making the two adjacent blades 402 more tightly sealed. Multiple blades 402 are arranged in a partially stacked manner. When subjected to backflow airflow, multiple blades 402 can prevent backflow of airflow, preventing dust, mud, sand, or rain and snow from flowing back into the air outlet, and effectively adapting to harsh environments such as deserts and heavy snow.

[0062] In the above embodiment, a filter screen 8 is fixedly provided at the air outlet end of the air guide 5.

[0063] In practical applications, the filter 8 can filter the backflowing airflow, preventing larger particles of mud and sand from entering the air guide 5 and causing blockage. The air outlet of the air guide 5 is arranged at an angle downward, which can also prevent larger particles of mud and sand from accumulating on the filter 8, ensuring that the air guide 5 is unobstructed in real time.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
