SURFACE ANODE EARTH ELECTRODE Russian patent published in 2017 - IPC C23F13/08 

FIELD: electricity.

SUBSTANCE: surface anode earth electrode comprised of a cylindrical body containing a gas outlet pipe and a current lead wire placed in a means of protection against damage during bending. Inside the cylindrical body cavity there is a cast electrode and a supporting frame. At the end faces it is provided with locking and fastening covers, upper and lower. The gas outlet tube contains an off-surface, subsurface areas and an area located inside the cylindrical body. A corrugated pipe of polymeric material with higher moisture resistance and impact resistance is used as a means of protection during bending. It is fixed in a hole on the upper locking and fastening cover and has a length of not less than the length of the off-surface and subsurface areas of the gas outlet pipe. A portion of the gas outlet pipe, located inside the cylindrical body, is spirally disposed around the supporting frame and is corrugated.

EFFECT: prevention of damage to the gas outlet pipe and the current lead wire when laying the anode earth electrode, increased effectiveness of gas removal and increased service life of the anode earth electrode.
