ANODE EARTHING DEVICE Russian patent published in 2016 - IPC C23F13/00 

FIELD: electricity.

SUBSTANCE: invention relates to metal structures electrochemical protection against corrosion in soil and can be used for subsurface and surface anode earthing production. Anode earthing electrode comprises cast electrode and current lead wire connected to it by means of contact unit, cast electrode has shape of hollow cylinder with external diameter of 70-80 mm and internal diameter of 35-40 mm, with open end face and through channels with cross section shape in form of rectangle with rounded edges and length of 10-15 mm and width of 5-7 mm, wherein channels are arranged in vertical rows with uniform pitch, in rows initial points arrangement displacement alternates in one row through distance, equal to pitch half, and angle between rows longitudinal axes is 120°, electrode inner space is filled with moisture adsorbing material, contact unit is equipped with insulating shell.

EFFECT: anode earthing device provides stable electrochemical protection under conditions of soil moisture content reduction.
