Abstract
Abstract
The corrosion causes of the grounded flat steel of a 110kV transmission tower were experimentally analyzed by means of macro testing, microstructure inspection, chemical composition analysis, corrosion product morphology and energy spectrum, galvanized layer thickness test, soil physical and chemical property analysis and other test methods. The results show that the improper selection of anti-corrosion process of grounded flat steel and the service environment of alkaline and high salt are the main reasons for its corrosion fracture. It is proposed that the power grid equipment should not use the grounding flat steel of cold galvanizing process, and the inspection of the grounding flat steel of the transmission tower in the Irrigation areas along the Yellow River should be strengthened.
