ANODE GROUNDING (VERSIONS) Russian patent published in 2017 - IPC C23F13/16 

FIELD: electricity.

SUBSTANCE: anode grounding comprises the current lead wire, the electrode of a low-soluble polymeric carbonaceous material, and the contact assembly; the electrode is made cylindrical, from the mixture of polyurethane (10-30 wt) and a low-soluble carbonaceous material (70-90 wt %, compacted at a pressure of 10-50 MPa and a temperature of 18-25°C.). The contact assembly comprises the stud pressed along the electrode axis; according to the first version of the anode grounding, the current lead wire is fixed on the non-pressed part of the stud by means of fixing nuts, the insulating shell is arranged in the electrode butt above the contact assembly. According to the second version of the anode grounding, the current leads wires are fixed on the non-pressed parts of the stud in both butts of the electrode.

EFFECT: reduction of energy consumption for the cathodic protection, improving the conservation of the current lead wire contact with the electrode material, reducing the degradation rate of the anode grounding in the operation process.
