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 electricalconnection between the successive cells (pots) arranged in series for theproduction of aluminium by electrolysis of alumina dissolved in moltencryolite, by the Hall-Heroult process. The invention is applied to series ofcells arranged transversely to the axis of the series (line) and operating ata current greater than 300 kA and possibly above 600 kA. The present inventioncombines the different advantages of known design concepts into effectivenovel technical solutions for large pots. The solution optimises the resultingmagnetic field and busbar performance parameters like voltage drop, weight,current distribution, distribution and average levels of magnetic field, inter-row distance, anode riser solutions and physical space for the busbarrequirements.
