The invention provides a moisture-resistant and corrosion-resistant PLC control cabinet applied to an underground humid environment. The moisture-resistant and corrosion-resistant PLC control cabinetcomprises a control cabinet body, a refrigeration fan used for cooling is installed in the control cabinet body, a plurality of groups of heat dissipation holes are correspondingly formed in the sideplate of the control cabinet body at the air outlet of the refrigeration fan, protective coatings are arranged on the surfaces of side plates on the periphery of the control cabinet body, each protective coating comprises a rubber insulating layer, a corrosion-resistant structural layer and a waterproof coating, one sides of the rubber insulating layers are bonded with the side plates of the control cabinet body, the other sides of the rubber insulating layers are bonded with the corrosion-resistant structural layers. According to the control cabinet, through cooperation of the epoxy resin coating and the silicon dioxide coating which are coated on the surfaces of the outer side plates around the control cabinet body, the corrosion resistance of the side plates of the cabinet body can be effectively improved, and the service life of the control cabinet body is further prolonged.
Description
technical field [0001] The invention relates to the field of industrial control cabinet equipment, in particular to a moisture-resistant and corrosion-resistant PLC control cabinet used in underground humid environments. Background technique [0002] The PLC control cabinet refers to the programmable control cabinet, and the control cabinet can realize the control of the motor and the switch. The PLC control cabinet has protection functions such as overload, short circuit, and phase loss protection. The control cabinets are combined to realize the independent automatic control of a single control cabinet, and multiple or multiple sets of control cabinets form a set (DCS) control system through industrial Ethernet or industrial field bus networks. PLC control cabinets can adapt to various sizes Industrial automation control occasions, and widely used in electric power, chemical industry, papermaking, environmental protection and sewage treatment and other fields.
