| 摘要 |
A cathode busbar system for an electrolytic cell of substantially rectangular shape, suitable for the Hall-Heroult electrolysis process, said electrolytic cell comprising a cathode forming the bottom of said electrolytic cell and comprising a plurality of parallel cathode blocks, each cathode block being provided with at least one current collector bar and two electrical connections points, a lateral lining defining together with the cathode a volume containing the liquid electrolyte and the liquid metal resulting from the Hall-Heroult electrolysis process, said cathode and lateral lining being contained in an outer metallic shell, and said electrolytic cell further comprising a plurality of anode assemblies suspended above the cathode, each anode assembly comprising at least one anode and at least one metallic anode rod connected to an anode busbar, said cathode busbar system comprising a ring busbar, surrounding said outer metallic shell viewed from above, said ring busbar being substantially rectangular and defining a main plane (PR), a median longitudinal plane (PX) as well as a median transversal plane (PY), both orthogonal to said main plane (PR), said ring busbar comprising two opposite and parallel longitudinal parts each extending along the long sides of the cell, and two opposite and parallel transversal parts extending along the ends of the cell, said ring busbar being symmetric with respect to said median transversal plane (PY), said cathode busbar system being provided with connection means for connection with both electrical connection points of each cathode block of the cell, said cathode busbar system being characterized in that said ring busbar is asymmetric with respect to said median longitudinal plane (PX). |
