Technical Field
[0001] The utility model relates to the technical field of PLC control cabinets, and specifically relates to a moisture-proof PLC control cabinet. Background Art
[0002] PLC control cabinet is an integrated equipment specially designed to provide automation control solutions for engineering sites. It is mainly composed of a control cabinet and a PLC control system. The PLC control cabinet uses a programmable logic controller (PLC) as the control core, which can realize real-time monitoring, data acquisition, control output and other functions of the entire system, thereby realizing automatic control of related equipment. PLC control cabinets are widely used in various industrial sites, such as machinery manufacturing, electric power, petrochemical, metallurgy, chemical industry, building materials, municipal engineering, etc., so they have been widely used in the field of industrial automation.
[0003] However, the PLC control cabinet will be affected by the humid environment. The humid environment will cause the circuit boards, electronic components and other parts inside the control cabinet to get damp, thus affecting the normal operation of the equipment. It will also cause the insulation performance between the circuit boards to deteriorate, causing short circuit failures. The humid environment will also damage the electronic components, causing equipment performance to deteriorate or fail to work properly. Moisture will also cause the program of the PLC control system to be disordered, affecting the normal operation of the equipment. In summary, moisture in the PLC control cabinet will affect the normal operation of the equipment, resulting in reduced production efficiency, product quality problems and other disadvantages. Therefore, we propose a moisture-proof PLC control cabinet to ensure the normal operation of the overall equipment. Utility Model Content
