A dual current supply system for aluminum-producing electrolyzers longitudinally arranged in a series-connected row comprises at least four anode risers in each space between next-adjacent electrolyzers. The system includes anode systems and anode buses electrically connected to the anode risers for supplying current from the anode risers to the anode systems. Two of the anode risers of one of a pair of next-adjacent electrolyzers are coaxially positioned in the space between the next-adjacent electrolyzers and two of the anode risers of the other of the pair of next-adjacent electrolyzers are positioned in the space between the next-adjacent electrolyzers in coplanar relation with the anode risers of the one of the next-adjacent electrolyzers. The arrangement of the anode risers enables a more uniform distribution of the magnetic field and permits the total length of the electrolyzer body and current supply buses to be reduced.

Dual current supply system for aluminum-producing electrolyzers

A system of busbars for aluminium-producing electrolyzers located at the ends of groups of series-connected electrolyzers arranged lengthwise in at least two parallel rows, incorporates stacks of cathode buses located to the left and to the right of a longitudinal axis of each row of electrolyzers in the direction of the current flow through the electrolyzers. The system incorporates a busbar jumper connecting the busbars of the first electrolyzer located at the end of one of the two rows of electrolyzers wih the busbars of the second electrolyzer located at the end of the other of the two rows of electrolyzers. The left stack of the second electrolyzer includes a portion which extends along the transverse wall of the electrolyzer towards the longitudinal axis thereof, and a continuing portion extending along said longitudinal axis, whereas the left stack of the first electrolyzer includes a portion which extends lengthwise of the transverse wall of the electrolyzer towards the right stack thereof, and a continuing portion extending together with the right stack of this electrolyzer to its junction with the busbar jumper. The proposed system permits minimizing the adverse effect of the magnetic field on the melt in the electrolyzer located at the end of the row, at the current outlet.
