PREFABRICATED GROUNDING AND LIGHTNING PROTECTION SYSTEM AND METHOD OF ITS INSTALLATION Russian patent published in 2020 - IPC H01R4/66 

FIELD: instrument engineering.

SUBSTANCE: invention relates to an earthing arrangement. Arrangement includes a vertical prefabricated grounding electrode consisting of at least two grounding rods, at least one coupling and a tip, a hot-dip galvanized steel strip with a width of up to 0.05 meters or a circular conductor with a diameter of 0.01 to 0.016 meters, the connection of which to the prefabricated grounding electrode is carried out by means of clamps with a width of 0.09 meters and a height of 0.09 meters. Way to install a prefabricated grounding system is as follows: before the vertical immersion of the first grounding rod of the prefabricated grounding electrode onto the rod, the receiving head and the mounting sleeve are screwed from above up to the stop, and the tip is screwed from the bottom up to the stop. Electrically conductive lubrication is applied to the electrically conductive thread, then the immersion is strictly vertical. After immersion, the mounting sleeve and the receiving head are unscrewed and disconnected from the grounding rod, then the connection of the next grounding rod is made through the coupling to the first rod. Operations are repeated until the required electrical resistance value of the grounding rod and the length of the grounding rod are obtained, after which the gaps are sealed.

EFFECT: technical result is the reduction in the electrical resistance of the rod-clamp-conductor connection, as well as the elimination of the destruction of the prefabricated grounding electrode when it is installed, reduction and stabilization of the resistance of the grounding arrangement.
