With large-scale electrolytic cells developed in recent years, 500kA 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 500kA 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.
