WORKING EARTHING ELECTRODE Russian patent published in 2011 - IPC H01R4/66 

FIELD: electricity.

SUBSTANCE: electrode includes current lead located in soil (1) in well (2) and having waterproof and electrically insulating cover of upper zone in the form of single-core electric cable (3) and metal electrode (4) of lower zone with open current-conducting surface and located in casing pipe (5) with perforation and with carbon filling (7). Cable (3) at the point of connection (8) to metal current lead of lower zone (4) is waterproof. Casing pipe (5) is equal as to height to deepening of lower zone of working earthing electrode to water-bearing bed (9) and closed on both ends, perforation holes (6) of casing pipe (5) are of smaller size than fractions of carbon filling (7). When there are no water-bearing soils, metal electrode 4 of lower zone is installed in mesh (10) container with carbon filling (7).

EFFECT: improving and cheapening of working earthing design, enhancing its conducting properties, and providing safety during its operation.
