Application Of Ion Earthing Electrode And Anti-corrosion Synthetical Reconstruction Technique In Reconstruction Of Grounding Grids

摘要：

Grounding grids play an important role in guarantee the safe operation when the station has encountered the short circuit or be attacked by lighting.Grounding grids must reconstruct when grounding resistance does not meet the regulation requirements.Using ion earthing electrode to reconstruct the grounding grid will cost less and have better effect.However, this way may increase the corrosion of grounding grid.In this paper, “ Ion earthing electrode with anti-corrosion grounding grid reconstruction technique is presented.This technique not only exerts the advantages of ion earthing electrode but also prevents grounding grid from corrosion.It was applied in 500kV Aijiachong power station, 220kV Nanzhutang power station, and so on.Grounding resistances of these power stations reached prospective effect after reconstruction.
