摘要
近年来,随着电解槽的大型化,500 kA级铝电解槽已逐渐成为新建电解铝项目的主流;而500 kA电解槽的母线配置主要分为自补偿和外补偿两种,分析其各自磁场及经济性的优劣,对新建项目采用哪种母线配置方式具有很好的指导作用。本文通过对500 kA铝电解槽自补偿及外补偿母线配置的磁场进行仿真模拟,将其磁场计算结果进行对比,分析了各自的优劣;并结合工程实际建设中的母线用量及厂房占地面积,对其经济性做进一步的分析,得出结论。
With large-scale electrolytic cells developed in recent years, 500 kA aluminum electrolytic cells have gradually become prevalent in new electrolytic aluminum projects and their busbar configuration is mainly divided into self-compensation and external compensation. The magnetic field and cost-effectiveness of these two compensation methods are analyzed so as to provide guidance for new projects on selecting busbar configuration method. This paper has simulated the magnetic field of self-compensating and external compensating busbar configuration in 500 kA aluminum electrolytic cells, compared calculation results, and analyzed strengths and shortcomings of these two compensation methods. In addition, this paper has further analyzed the cost-effectiveness of these methods and drawn a conclusion based on busbar consumption and plant footprint in actual project construction.
