Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, in particular to a moisture-proof control cabinet. Background Art

[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, be easy to maintain, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In the event of a fault or abnormal operation, the circuit can be cut off or an alarm can be issued with the help of protective electrical appliances.

[0003] Control cabinets are widely used in industries such as electricity, metallurgy, chemical industry, papermaking, environmental protection and sewage treatment. However, when the existing control cabinets are in use, moisture can easily enter the cabinet through the heat dissipation vents on the cabinet. After the water vapor accumulates in the cabinet, it adheres to the controller and easily causes a short circuit in the controller. When the control cabinet is in use, moisture can also enter the cabinet through the connection gap between the cabinet door and the cabinet. The moisture-proof performance of the cabinet is poor. In addition, when the existing control cabinet is ventilated, impurities in the air are not filtered, resulting in impurities entering the control cabinet, reducing the applicability of the device. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0019] 1. The utility model installs filter screen 1, moisture absorption plate and filter screen 2 at the bottom end of the mounting seat in sequence, and then inserts the mounting seat into the inside of the boss, and then rotates two sets of limit blocks inward at the same time until the side ends of the limit blocks and the top end of the mounting seat are in conflict, so that the mounting seat can be limited by the limit blocks. When filter screen 1, moisture absorption plate and filter screen 2 need to be replaced, it is only necessary to rotate the limit blocks to both ends to release the limit on the top end of the mounting seat, and then pull the mounting seat upward.

[0020] 2. The utility model turns on the fan, which draws air outside the cabinet from the filter cover into the cabinet, to achieve ventilation inside the cabinet. External air enters from the filter cover, passes through filter screen 1, desiccant plate and filter screen 2 in sequence. Filter screen 1 and filter screen 2 can filter out particulate impurities of different particle sizes in the air to prevent impurities from entering the cabinet, while the desiccant plate can absorb moisture in the air. Finally, the air is heated by the heating tube at the vent to thoroughly dry the air. BRIEF DESCRIPTION OF THE DRAWINGS
