摘要
介绍了制药厂发酵罐用变频器干扰DCS自动控制系统的实例分析及干扰处理方法。通过在变频器输入、输出端加装匹配的电源滤波器,有效解决了变频器工作时产生的电磁干扰。经过多次整机调试及试验,实现了制药厂发酵车间DCS自动化控制系统与变频器的电磁兼容。
This text introduced the pharmaceutical factory of system ferments a solid an analysis and interferences for using the inverter interference DCS automatic control systems handles method. Pass to input,output in the Inverter the power filter that carry add to match, solving the EMI that hour of inverter work produce effectively. Passing by many whole machine adjusts to try and experiment, realizing the pharmaceutical factory of system ferment the car a DCS Automatic control system and inverter EMC.
