DEVICE FOR ELECTRIC CONNECTION BETWEEN TWO SERIAL ELECTROLYTIC CELLS OF SET OF ELECTROLYTIC CELLS FOR PRODUCTION OF ALUMINIUM

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to device for electrical connection of electrolytic cells for aluminium production in series of concatenated electrolytic cells (N-1) and (N) by Hall-Heroult method. Device comprises first conductor connected with the cathode of electrolytic cell (N-1) and with anode frame of electrolytic cell (N) and provided with section located between said cells (N-1) and (N) wherein current flows in direction of cells levelling axis (x). Second conductor is connected with the cathode of cell (N) and anode frame of cell (N+1) provided with section located between cells (N-1) and (N) wherein current flows from said axis (x). Shunting wedges are arranged between said sections of said conductors. Third conductor is arranged to equalise the current flowing in said wedges. Invention discloses also the method of shunting of electrolytic cell (N) in series of electrolytic cells.EFFECT: better compensation for magnetic field effects at shunting of electrolytic cell for its deactivation.10 cl, 6 dwg
