IMPROVED SYSTEM OF MEASUREMENT AND CONTROL OF ELECTRIC CURRENT FOR CELL PLANTS Russian patent published in 2018 - IPC C25B15/02 H02J7/04 C25C7/06 C25D17/02 

FIELD: electricity.

SUBSTANCE: invention relates to a method and a system of electric current control (ECM) in at least one electrolysis cell having at least two electrodes in contact with an electrolytic medium, a plurality of touch sensitive measuring instruments for a current passing through one or more electrodes, besides the mentioned touch sensitive instruments are located within at least one ECM panel installed in one or more operating electrolysis cells. The system also includes the supporting means for supporting at least one ECM panel in electrolysis each cell, the supporting means being arranged to prevent disturbances in normal electrode movements and damage of the ECM panel. The system is executed with a possibility to measure an electric current passing through an electrode or a plurality of electrodes in the electrolysis cell. These improvements include means for minimization of impacts on measurement of current of variables of several types, for example, electromagnetic interference, electrolysis cell geometry and contact configuration, in order to provide a reliable approximation of the current passing through each electrode. In addition, the aforementioned improvements relate to maximizing the functionality, adaptability and manageability of the device, providing a complete upgrade of the metallurgical systems, in which it is important to provide reliable control of the electric current passing through the electrodes.

EFFECT: increase in the accuracy of real-time monitoring of current magnitude passing through each cathode or anode contained in the electrolysis cell of electrolytic refining of metals, as well as optimisation of the electrolysis cells operation.
