[0002] In the field of substation secondary cabinet heat dissipation technology, existing solutions have technical bottlenecks, such as: air duct design flaws: traditional air ducts cannot distinguish the heat dissipation needs of the cabinet body and internal components, leading to a high temperature difference between the cabinet surface and internal components; and insufficient sealing performance: the locking mechanism between the cabinet body and the door has gap leakage problems, resulting in poor airflow efficiency. These problems result in poor ventilation and heat dissipation functions for the secondary cabinet. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a secondary screen cabinet with an air supply device, which can solve the problems in the prior art.

[0004] This utility model is achieved through the following technical solution: A secondary cabinet with an air supply device includes an air conditioner blower, a first air duct connected to the air conditioner blower, multiple cabinet components connected in series, a second air duct, and a third air duct.

Second air ducts are connected between the first air duct and the cabinet components, between the cabinet components, and between the cabinet components and the third air duct. Each cabinet component includes a cabinet body, and a switchable air duct is provided inside the cabinet body. A cabinet door is hinged to the front of the cabinet body, and the cabinet door and the cabinet body are kept closed by a locking component. Two bottom air ducts are provided at the bottom of the cabinet body, and the bottom air ducts are connected to the interior of the cabinet body.

[0012] In a further technical solution, the plug-in plate is provided with an inclined surface, which is used to engage with the slot after the plug-in plate moves.

[0013] The beneficial effects of this utility model are as follows: First, by setting up an air conditioner blower, a first air duct, a second air duct, a cabinet assembly, and a third air duct, cold air is made to flow between the cabinet assemblies, effectively removing the heat from the cabinet assemblies. In addition, a switchable air duct is set up, which can specifically ventilate and dissipate heat on the components in the cabinet or the inner cavity. The purpose of dissipating heat on the cabinet is that when the temperature of the external space is high, the cabinet can be dissipated first, and then the inner cavity can be dissipated, which can help to dissipate heat and lower the temperature.
