DEEP ANODE EARTH ELECTRODE Russian patent published in 2017 - IPC H01R4/60 

FIELD: electricity.

SUBSTANCE: deep anode earth electrode contains a cylindrical housing filled with activator, with locking and fixing lids; the supporting frame containing rods connected by U-shaped plates is installed in the cavity of the cylindrical body; and the cast electrode with the current lead wire. The deep anode earth electrode additionally comprises an elastic shell fixed to the side surfaces of the locking and fixing lids and metal washers sectioning the activator, the washers being installed perpendicular to the earth electrode axis at a distance of 200-250 mm from each other and having: the outer diameter of 6-10 mm less than the inner diameter of the cylindrical body; the inner diameter of the 6-10 mm more than the electrode diameter; openings coaxial to the frame rods, with the diameter of 4-6 mm more than the diameter of the rods, the cylindrical body being made twisted and connected to the support frame by metal plates.

EFFECT: ensuring uniform distribution of current along the electrode surface and the activator volume due to providing the maximum contact area of the activator with the ground in various operating conditions.
