A METHOD FOR ELECTRICAL CONNECTION AND MAGNETIC COMPENSATION OF ALUMINIUM REDUCTION CELLS, AND A SYSTEM FOR SAME

摘要

The present invention relates to a method and a system for electrical connection between the successive cells (pots) arranged in series for the production of aluminium by electrolysis of alumina dissolved in molten cryolite, by the Hall-Heroult process. The invention is applied to series of cells arranged transversely to the axis of the series (line) and operating at a current greater than 300 kA and possibly above 600 kA. The present invention combines the different advantages of known design concepts into effective novel technical solutions for large pots. The solution optimises the resulting magnetic field and busbar performance parameters like voltage drop, weight, current distribution, and distribution and average levels of magnetic field, inter-row distance, anode riser solutions and physical space for the busbar requirements.
