ANODE BUSBAR OF ALUMINIUM ELECTROLYSER WITH BACKED ANODES Russian patent published in 2017 - IPC C25C3/16 

FIELD: electricity.

SUBSTANCE: busbar contains a bus cable consisting of bus forming a closed loop with aluminium bridges and interconnected by transverse steel spacers, the anodes fixed with a specified pitch on the buses of the bus cable using clamps. The buses in the bus cable are of different thicknesses forming a variable cross-section of the bus cable along its length with a reduction of the cross-section in the direction of current flow in the bus cable, and the bus width (b, mm) at a certain length of the bus cable, multiple of the step of the anodes installed on the bus cable, is: where: j_sr - the average current density in the bus cable, A/mm²; H - bus height, mm, I_i - the current strength measured in the direction of the current in the cross-section of the bus before each anode fixed on this bus, A; K - the number of anodes fixed on one bus, pcs; the average current density in the bus cable is 0.2-0.8 A/mm², and the height of the bus H is a constant value.

EFFECT: more efficient use of current-carrying buses in the electrolyser, uniform distribution of current through the anode busbar, and reduction of weight and consumption of the material of the current-carrying structure.
