Abstract

The invention relates to the technical field of grounding body corrosion prevention and resistance reduction, in particular to an environment-friendly long-acting electrolytic ion grounding electrode and a construction method thereof. The electrolytic ion grounding electrode disclosed by the invention is a compound grounding electrode composed of a steel wire grounding electrode, an electrolytic ion source and electrolytic ion carriers, wherein the electrolytic ion source is connected with the steel wire grounding electrode; one end of a lead-up wire is connected with the electrolytic ion source, and the other end of the lead-up wire is led onto the ground surface; and the electrolytic ion carriers are wrapped on the steel wire grounding electrode and the periphery of the electrolytic ion source. The environment-friendly long-acting electrolytic ion grounding electrode can solve the resistance reduction problem in high earth resistivity areas such as rocky mountain, gravel and rubble terrains, and can successfully solve the corrosion problem of low earth resistivity in salt and alkali low bogs, resistance value stability problem and relatively frequent maintenance change.

Description

technical field [0001] The invention relates to the technical field of grounding body anticorrosion and resistance reduction, in particular to an environment-friendly long-term electrolytic ion grounding electrode and a construction method thereof. Background technique [0002] In order to ensure the safe operation of transmission lines and substations (stations), in terms of grounding, two problems must be solved at the same time. One is the problem of resistance, that is: whether the grounding resistance of the grounding electrode and the grid can stably meet the requirements stipulated in the GB50169-2006 and DL / T62l-1997 standards; the other is the corrosion of the grounding electrode and the grid, that is: how to prevent The corrosion caused by the synergistic effect of dissolved oxygen in soil and groundwater and chloride ions on the grounding electrode and grid leads to the reduction of its cross-sectional area, resulting in disconnection or even loss of grounding, wh...
