[0003] At present, the existing ground power cabinet on the market usually includes an external cabinet body and electrical elements installed in the cabinet body. In the above-mentioned structure, the ground power cabinet has less influence on the environment in dry and less rainy scenes, and can maintain its use stability and safety for a long time. However, when installed and used in southern or coastal areas, due to high air humidity and abundant rainfall, condensation problems are easy to occur, which reduces the insulation performance of the cabinet. Therefore, the industry usually sets up a dehumidification structure in the ground power cabinet used in such scenes to dehumidify the air in the cabinet. For example, a high-frequency switch DC power cabinet disclosed in patent CN215119578U sets up a dehumidification box inside the bottom end of the cabinet body, and the dehumidification box is placed with a dehumidifier. The dehumidification box and the base are plugged together. The dehumidifier in the dehumidification box absorbs the moisture in the air in the cabinet body, and when the dehumidifier is used to the predetermined degree, the dehumidification box is taken out to replace the dehumidifier, which meets the demand of keeping the air in the cabinet dry, avoids the problem of rusting and damage of internal structural parts and failure of electrical elements caused by long-term use in a humid environment, and better adapts to the humid environment. Although the above-mentioned structure of the ground power cabinet can meet the dehumidification demand and be used in a humid environment, since the dehumidification is carried out by using a dehumidifier with limited adsorption capacity, it is difficult to remove the moisture in the subsequent humid air after the air in the cabinet body flows. In addition, the dehumidifier needs to be replaced frequently, which is time-consuming and labor-intensive, and the problem of not replacing it in time is easy to occur, which affects the use performance and still has safety hazards.

At the same time, the air outlet 5 and the air inlet 4 are distributed in high-low state in the vertical direction, which can fully utilize the characteristics of low and high temperature air, is beneficial to inhale air with lower temperature, and can maximize and efficiently exhaust hot air, so as to ensure that the air flow is smoother and the equipment normal working temperature is maintained. In addition, the heating assembly 3 is installed in the cabinet body 1 and located at the air inlet 4, and the air entering the air inlet 4 flows through the heating area of the heating assembly 3, so that the air entering the cabinet body 1 can be heated and dried at the first time, ensuring that the air passing through the electrical elements 2 in the cabinet body 1 is dry air, realizing the protection of the electrical elements 2, reducing the influence on the insulation performance, and improving the safety.
[0025] In addition, the embodiment further provides another ground power cabinet with a dehumidification structure, that is, the above-mentioned heating assembly 3 is replaced by a dehumidifier, that is, a dehumidifier is arranged in the cabinet body 1 and located at the air inlet 4, that is, the air entering the air inlet 4 first passes through the dehumidifier for dehumidification operation, and the dehumidified air is discharged into the cabinet body 1, and finally discharged through the air outlet 5, which can also meet the use requirement of dehumidifying and drying the air entering the cabinet body 1.

[0031] More specifically, the air inlet 4 and the air outlet 5 are arranged on both sides of the cabinet 1 in the length direction, that is, the entire cabinet 1 is used as an air duct, and the flow of the air in the air duct can completely cover each electrical element 2 in the cabinet. In addition, only the air inlet 4 and the air outlet 5 are connected with the outside when the cabinet door is closed, so that the leakage problem of other areas of the cabinet 1 is avoided, thereby avoiding the problem that the air enters the cabinet 1 from other places of the cabinet 1 without being heated by the heating assembly 3, and the dehumidification and drying effect of the air in the cabinet 1 is poor. In addition, the height of the air outlet 5 is higher than that of the air inlet 4, the characteristic that hot air is located at the upper layer of the cabinet 1 is fully utilized, the air in the cabinet 1 is quickly discharged, the circulation and smooth flow of the air in the cabinet 1 are realized, and the normal operation demand of the ground power cabinet is met.
