Abstract

The invention discloses an anti-corrosion resistance reduction agent for a copper ground grid. The anti-corrosion resistance reduction agent for the copper ground grid is characterized by being made from, by weight, 2-6 parts of sodium bicarbonate, 0-2 parts of sodium carbonate and 80-120 parts of water. The anti-corrosion resistance reduction agent avoids loss of water in soil to enable soil resistivity to be relatively stable, and resistance reduction is realized while chemical corrosion and electrocorrosion of copper pipes and steels are avoided.

Description

[0001] Technical field: [0002] The invention relates to an anti-corrosion and drag-reducing agent, in particular to an anti-corrosion and drag-reducing agent for copper grounding grids. Background technique: [0003] In recent years, with the implementation of the protection of cultivated land and environmental protection policies, most substations are selected in high soil areas. During the construction period, it is extremely difficult to achieve a grounding resistance of less than 0.5 ohms; and the grounding resistance will rebound and rise after acceptance and operation; Even after deep well resistance reduction treatment (water combined with resistance reduction agent) is used again, the phenomenon of ground resistance rebound and increase still occurs, which is mainly caused by water loss or drought season. [0004] At present, most compact substation grounding grids in high soil areas use copper grounding grids, which solves the corrosion problem of steel grounding ...
