Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of switch cabinets, and particularly relates to a ventilated switch cabinet base. BACKGROUND

[0002] In the operation of a power system, a switch cabinet as a core power distribution equipment directly affects the safety and reliability of power transmission. With the continuous increase of power load, heat is continuously generated when electrical components in the switch cabinet are in operation. If the heat cannot be dissipated in time, the temperature in the cabinet will rise, which not only reduces the insulation performance of the components, but also may cause a fault and affect the stability of power supply. At present, the heat dissipation of a traditional switch cabinet mainly depends on the air inlet and heat dissipation openings formed in the cabinet body. The air inlet is usually arranged at the middle upper part of the cabinet body. However, this design has obvious defects. On the one hand, the middle upper air inlet is easy to suck in air with a high temperature at the upper layer, and the heat dissipation efficiency is low, which is difficult to meet the heat dissipation demand under high load conditions. On the other hand, although some switch cabinets are additionally provided with a fan for heat dissipation, the fan is usually installed inside the cabinet body, which is directly in a high temperature environment, and the service life is greatly shortened. In addition, when the fan is maintained, it is necessary to enter the inside of the cabinet body to operate, which is complicated and increases the maintenance cost and safety risk. SUMMARY

[0003] To solve the above technical problems, the technical scheme adopted by the application is as follows: a ventilated switch cabinet base comprises an upper bottom plate, a lower bottom plate and a plurality of side plates, the two ends of each side plate are fixedly connected with the upper bottom plate and the lower bottom plate, the adjacent side plates are fixedly connected, a partition plate is arranged between the upper bottom plate and the lower bottom plate, the four sides of the partition plate are fixedly connected with the side plates, an upper space is formed between the partition plate and the upper bottom plate, a lower space is formed between the partition plate and the lower bottom plate, a plurality of threaded holes are arranged at the four sides of the upper bottom plate, a plurality of air outlet holes are arranged on the upper bottom plate and are uniformly spaced, the air outlet holes are communicated with the upper space, a plurality of installation openings are arranged on the partition plate, the upper space is communicated with the lower space through the installation openings, a fan is arranged in each installation opening, some or all of the side plates are provided with an air inlet, and the air inlet is communicated with the lower space, a plurality of I-shaped steel beams are arranged in the upper space and the lower space respectively, the upper surface of each I-shaped steel beam is connected with the upper bottom plate or the partition plate through a plurality of bolts, and the lower surface of each I-shaped steel beam is connected with the lower bottom plate or the partition plate through a plurality of bolts.

[0004] As a preferred technical scheme of the above technical scheme, the I-shaped steel beams in the upper space and the I-shaped steel beams in the lower space are vertically staggered.

[0005] As a preferred technical scheme of the above technical scheme, the lower surface of the lower bottom plate is threadedly connected with a plurality of support rods, and the lower end of each support rod is fixedly connected with a support plate.

[0006] As the preferred technical scheme of the above, the support rods are respectively located below the I-shaped steel beams inside the lower space.

[0007] As the preferred technical scheme of the above, the filter screen is installed on the filter screen frame, and the filter screen frame is buckled with the side plate.

[0008] The ventilated switch cabinet base has the following advantages: the air inlet is arranged on the base (at a lower position), low-temperature air is sucked in, the fan in the lower space sends air upward, the air enters the cabinet body through the air outlet in the upper space, and the heat dissipation efficiency is improved; the fan is located in the base and is far away from the high-temperature area of the cabinet body, the working environment is better, and the service life is prolonged; maintenance does not need to enter the cabinet body, operation is simple, cost and safety risk are reduced.

The cabinet body of the switch cabinet is installed on the base through the threaded holes 7. The air inlets 11 on the base inhale air, the fan 10 sends the air into the upper layer space 5, the air in the upper layer space 5 passes through the air outlet holes 8 and enters the interior of the cabinet body, and the hot air in the cabinet body is discharged from the heat dissipation holes at the upper end of the cabinet body. Compared with the conventional switch cabinet in which the air inlets are arranged on the cabinet body, the air inlets 11 on the base are arranged at a lower position, the influence of the air with a higher temperature on the upper layer is reduced, and the temperature of the inhaled air is lower. Meanwhile, the fan 10 is arranged at a lower position and is not directly affected by the hot air, so that the working environment is better and the service life can be improved. The fan 10 is more convenient to maintain and does not need to be maintained in the interior of the cabinet body.

[0017] Further, the support rods 13 are located below the I-shaped steel beams 12 in the lower layer space 6 respectively, and the threaded holes on the lower bottom plate 2 extend into the corresponding I-shaped steel beams 12. In this way, the I-shaped steel beams 12 can bear the maximum stress, the deformation of the lower bottom plate 2 is reduced, and the stability and service life of the entire base are improved.

[0018] Further, the air inlet 11 is covered with a filter screen 15 respectively. The filter screen 15 traps dust and other garbage, preventing garbage from being sucked into the base.

[0019] Further, the filter screen 15 is installed on a filter screen frame, and the filter screen frame is buckled with the side plate 3. The filter screen 15 is convenient to disassemble and clean, preventing the filter screen 15 from being blocked, and ensuring the air flow of the air inlet 11.
