Aluminium Smelter Comprising a Compensating Electric Circuit

摘要

This aluminum smelter comprises a row of cells (50) arranged transversely in relation to the length of the row, the cells (50) individually comprising an anode (52), rising and connecting electrical conductors (54) running upwards along the two opposite longitudinal edges of the cell (50) to route the electrolysis current towards the anode (52), and a cathode (56) through which pass cathode conductors (55) connected to cathode outputs connected to linking conductors to route the electrolysis current to the rising and connecting electrical conductors of the next cell (50). Furthermore the aluminum smelter comprises a compensating electrical circuit separate from the electrical circuit through which the electrolysis current flows, running beneath the cells (50), through which a compensating current may flow beneath the cells (50) in a direction opposite to the overall direction of flow of the electrolysis current.

主权项

1. An aluminum smelter comprising at least one row of electrolytic cells arranged transversely in relation to a length of the at least one row, each of the electrolytic cells comprising a pot shell, anode assemblies each comprising a support and at least one anode, and a cathode through which pass cathode conductors intended to collect an electrolysis current at the cathode to route the electrolysis current to cathode outputs outside the pot shell, characterized in that each electrolytic cell comprises rising and connecting electrical conductors to the anode assemblies running upwards along two opposite longitudinal edges of the electrolytic cell to conduct the electrolysis current to the anode assemblies, and linking conductors connected to the cathode outputs designed to route the electrolysis current from the cathode outputs to electrical rising and connecting conductors of the next electrolytic cell, and in that the aluminum smelter comprises at least one electrical compensating circuit running beneath the electrolytic cells, through which compensating circuit may flow a compensating current flowing beneath the electrolytic cells in a direction opposite to an overall direction of flow of the electrolysis current passing through the electrolytic cells located above.
