Because PLC is a precision electronic product,the automatic control system requires long-term uninterrupted operation,so the operating environment of PLC is extremely high,and it must be dustproof,fireproof,waterproof,high temperature proof,and lightning proof.Therefore,the electrical control room is generally arranged On the second floor with double-glazed and water-type refrigeration and air conditioning,the temperature of the electric control room is generally controlled at about 28 degrees;for dust prevention,the PLC is installed on the front panel with a lock of 1M*2.2M*0.6M In the control cabinet with glass door,an exhaust system with dust cover is installed on the upper part of the cabinet to cool down the cabinet.
因为PLC为精密电子产品,自动化控制的系统是要求长时间不间断运行,因此PLC的运行环境要求极高,要防尘、防火、防水,防高温,防雷电,因此电气控制室一般都安排在具有双层玻璃的、安装有水式制冷空调的二楼,电控室的温度一般控制在28度左右;对于防尘则是将PLC安装在1M*2.2M*0.6M的带锁前面板为玻璃门的控制柜中,此柜上部安装有防尘罩的抽风系统进行柜内降温。
