Provided is an electrode assembly for electrolytic processing in an electrolysis cell comprising an electrode blade comprising a metallic hanger bar portion, a first lug for supporting the metallic hanger bar portion on a first power supply bar, an insulating piece connecting the metallic hanger bar portion to the first lug. The electrode assembly also comprises an electrical switch unit controlling electrical current supply between the first lug and the metallic hanger bar based on a control signal transmitted to a terminal of the electrical switch unit, a control unit configured to transmit the control signal to the terminal of the electrical switch unit, and a power storage unit configured to supply power to the control unit, the power storage unit being charged from the first lug and the hanger bar when the electrical switch unit switches off electrical current supply between the first lug and the metallic hanger bar.

Apparatus for protection of anodes and cathodes in a system of electrolysis cells

The invention relates to a method and current measuring arrangement for measuring electric current flowing in an individual electrode in an electrolysis system. The electrolysis system comprises a plurality of interleaved electrodes (), cathodes () and anodes (), arranged in an electrolysis cell () and immersed in electrolyte, said electrolysis system having a busbar () disposed on a separating cell wall () between each of the two adjacent cells to conduct electric current to the electrodes via a contact point () between the busbar and a hanger bar () of the electrode, and the current sensing arrangement comprises a magnetic field sensing means () for measuring the magnetic field induced by said current. The magnetic field sensing means () are arranged to sense the magnetic field substantially at the level of the contact point ().

Arrangement for measuring electric current in an individual electrode in an electrolysis system

The invention relates to a method and current measuring arrangement for measuring electric current flowing in an individual electrode in an electrolysis system. The electrolysis system comprises a plurality of interleaved electrodes (), cathodes () and anodes (), arranged in an electrolysis cell () and immersed in electrolyte, said electrolysis system having a busbar arrangement () disposed on a separating cell wall () between each of the two adjacent cells. The busbar arrangement comprises an equalizer busbar () to electrically connect anodes in one cell to cathodes in a next cell providing the current with multiple electrical pathways between electrodes, said electrical connection being formed by contact points () between the equalizer busbar () and hanger bars () of the electrodes. The electric current in the equalizer busbar () is measured by magnetic field sensing means () arranged at measuring points () located between each pair of the adjacently neighboring contact points ().
