Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a combined switch cabinet. Background Art

[0002] The switch cabinet is a kind of electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. The subway will set up a combination switch cabinet to store a large number of subway power supply equipment, and staff are required to regularly perform maintenance and inspection on the subway power supply equipment inside the combination switch cabinet to prevent failure of the subway power supply equipment and affect the normal operation of the subway.

[0003] The Chinese patent publication number is: CN219833533U discloses a modular switch cabinet for maintenance and inspection of subway power supply equipment. The application proposes: "The modular switch cabinet is composed of multiple groups of single switch cabinets, and the multiple groups of single switch cabinets are close to each other. The power supply equipment arranged inside the switch cabinet will generate more heat under long-term operation, resulting in no space for heat dissipation at the connection of the multiple groups of single switch cabinets, making it difficult for the heat at the connection between two adjacent groups of single switch cabinets to dissipate, affecting the overall heat dissipation of the modular switch cabinet and the safe operation of the power supply equipment inside the switch cabinet. In view of the above problems, we propose a modular switch cabinet for maintenance and inspection of subway power supply equipment." Although the application solves this problem, it has the following defects:

[0004] The above-mentioned existing technical solutions have the following defects: although the above-mentioned combined switch cabinet can rely on the heat dissipation holes to dissipate heat at the connection between two adjacent groups of single switch cabinets, the heat dissipation effect is not good because it only relies on the air circulation in the heat dissipation holes to dissipate heat, and it does not meet the daily use requirements. Therefore, we propose a new type of combined switch cabinet. Utility Model Content

[0029] See also Figure 1-4 Five fans 10 evenly distributed are fixedly installed on the inner side of the mounting frame 9. The fans 10 are used to speed up the air circulation speed in the gap between two adjacent switch cabinets of the subway power supply equipment switch cabinet, thereby speeding up the removal speed of the internal heat of the switch cabinet body 1, and at the same time prompting the outside to enter the cabinet faster, so as to achieve the effect of rapid heat dissipation of the switch cabinet body 1.

When it is necessary to dissipate heat at the connection between two adjacent groups of single switch cabinets of the subway power supply equipment switch cabinet, the fan 10 is started, and the fan 10 starts to work, which will speed up the air circulation speed in the gap between the two adjacent groups of switch cabinets, speed up the speed at which the hot air inside the switch cabinet body 1 is discharged to the outside, so that the hot air is quickly discharged outside the switch cabinet, and at the same time, the outside air is sucked into the gap at the connection between the two adjacent groups of switch cabinets. After the outside air is filtered by the dust filter 12, it enters the switch cabinet body 1 from the heat dissipation hole 2, so as to achieve the effect of rapid heat dissipation of the switch cabinet body, the heat dissipation effect is good, the heat dissipation efficiency is improved, and the daily use needs are met.

[0033] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model.
