Menetelmä elektrolyysijärjestelmän yksittäisessä elektrodissa virtaavan sähkövirran mittaamiseksi ja järjestely tätä varten

摘要

A current measuring arrangement for measuring electric current flowing in an individual electrode in an electrolysis system comprising a plurality of interleaved electrodes (1, 2), cathodes (1) and anodes (2), arranged in an electrolysis cell (3) and immersed in electrolyte, said electrolysis system having a busbar (4) disposed on a separating cell wall (5) between each of the two adjacent cells to conduct electric current to the electrodes via a contact point (6) between the busbar and a hanger bar (7) of the electrode, and the current sensing arrangement comprises a magnetic field sensing means (10) for measuring the magnetic field induced by said current. The magnetic field sensing means comprises an array of magnetic field sensors (10) arranged around the contact point (6) substantially at the level of the contact point (6) in a plane of the contact point.
