Aluminium smelter comprising a compensating electric circuit

摘要

This aluminium smelter comprises a line of cells (50) arranged transversely with respect to the length of the line, one of the cells (50) comprising an anode (52), riser and connecting electrical conductors (54) extending upwards along two opposite longitudinal edges of the cell (50) in order to conduct the electrolysis current to the anode (52), and a cathode (56) passed through by cathode conductors (55) connected to cathode leads connected to routing conductors for routing the electrolysis current to riser and connecting electrical conductors of the following cell (50). Furthermore, the aluminium smelter comprises a compensating electric circuit, different from the electric circuit travelled through by the electrolysis current, extending underneath the cells (50) and possibly being travelled through by a compensating current circulating under the cells (50) in the reverse direction to the overall circulation direction of the electrolysis current.
