Description

Technical Field

[0001] The invention relates to the technical field of power cabinets, and in particular to a moisture-proof power cabinet for outdoor use. Background Art

[0002] The power cabinet is a cabinet made of steel to protect the normal operation of components. The materials used to make power cabinets are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of power cabinets. The power cabinet is a control cabinet that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet according to the electrical wiring requirements. Its layout should meet the requirements for the normal operation of the power system, be easy to maintain, and not endanger the safety of people and surrounding equipment. For example, application number CN202222244932.3 is a lift-type power cabinet that is easy to maintain. This lifting structure is simply lifted by a cylinder. When used outdoors, rainwater seeps into the cylinder and easily causes internal damage, making the lifting structure unusable.

[0003] Based on the above, some existing power cabinets need to be set up outdoors, but the moisture-proof effect of outdoor power cabinets is too poor, and it is easy for moisture to enter through the bottom of the power cabinet, causing damage to internal electronic components, which poses certain safety hazards. In addition, there are often foreign flying insects entering the cabinet through the heat dissipation openings outdoors, which can easily affect the equipment installed inside the power cabinet, which is not conducive to the safe use of the equipment inside the power cabinet. Summary of the invention

[0004] In view of this, the present invention provides a moisture-proof power cabinet for outdoor use, which can lift the power cabinet by setting a lifting component to increase the distance between it and the ground, which can not only prevent the entry of moisture, but also prevent rainwater from penetrating too deeply into the interior of the power cabinet when it rains, thereby avoiding damage to internal components caused by moisture and reducing safety hazards. At the same time, it can also ensure that the bottom of the power cabinet will not be corroded by moisture. Through the setting of a drying structure, the moisture inside the power cabinet can be absorbed by a desiccant, thereby ensuring the dryness of the inside of the power cabinet. Through the setting of a protective component, it can prevent external flying insects from entering the cabinet to affect the equipment, thereby ensuring the safe use of internal equipment. At the same time, it can also prevent dust from entering the cabinet to affect the heat dissipation of the equipment.
