Abstract
The article presents the results of research on the energy efficiency of the main equipment of the electrolysis production in a metallurgical plant. The objects of research were the main and bypass busbars of the electrolysis shop. The temperatures of busbars, voltages on electrolyzers, voltage drop at busbar junctions, the operational state of busbars, the composition and content of impurities in busbars were experimentally determined, and the parameters of busbar electrical conductivity and voltage losses were determined analytically. The main purpose of the study was to substantiate the feasibility of replacing busbars and recommendations for improving the energy efficiency indicator during their operation.
