摘要:The influence of the high magnetic field environment on the control system of pot tending ma-chine is presented in this paper, an approximate calculation method for the magnetic field in the electro-lytic workshop is given. Through the measurement of the ground field and near the equipment in work-shop, the detailed technical analysis of the strong magnetic field is carried out in this paper. Finally, the protection and suppression measures are adopted in the design of the electronic control system, and the application effect is satisfactory.%本文提出了电解车间强磁场环境对电解机组电控系统的影响,给出了电解车间磁场的近似计算方法,同时,通过检测电解车间地面磁场及电解机组桥架附近磁场,对电解车间强磁场进行了详细的技术分析,给出了在电解机组电控系统设计中,采取的防护和抑制措施,取得了满意的效果.
