BUS ARRANGEMENT OF ELECTROLYSIS CELL FOR PRODUCING ALUMINIUM Russian patent published in 2014 - IPC C25C3/16 

FIELD: chemistry.

SUBSTANCE: bus arrangement comprises a partitioned cathode bus bar and an anode bus bar, wherein the anode bus bar has three stand pipes - blind input, front input and front output - with the possibility of distributing current fed to the electrolysis cell on the stand pipes, and is provided with jumpers on the anode bus bars at the input and output, characterised by that a second bus for the anode stand pipe is placed in parallel to the input stand pipe on the blind side of the previous electrolysis cell, said second bus being connected at the top to the input end of the anode bus of the previous electrolysis cell, and connected at the bottom to the cathode bus of the blind side of the previous electrolysis cell with a group of cathode rods closest to the output end and carrying 7-11% of the current load fed to the electrolysis cell.

EFFECT: invention enables to form a more uniform electric field in a melt which, coupled with good magnetic field properties, creates an optimum field of Lorentz forces and as a result high margin of magnetohydrodynamic stability and good cost/performance ratio of the electrolysis cell.
