Abstract

With the rapid development of the power grid, the soil corrosion problem of buried metallic components used for electrical equipments is increasing, which brings huge safety hazards to the power grid and leads to a significant increase in operation and maintenance costs. In this paper, the corroded grounding electrode used for electrical equipment in 220kV substation was investigated by means of microstructure analysis, macro-morphology inspection, soil physicochemical properties testing and energy spectrum analysis. The results show that insufficient anti-corrosion performance and alkaline service environment with high salt were the main causes for corrosion of grounding electrode. Additionally, effective suggestions were put forward in order to improve the corrosion resistance of the grounding electrode in order to ensure the safety and stability of the power grid.
