Formation and influence analysis of electrolytic corrosion products on insulator surface

Abstract Nowadays, end fitting corrosion reduces the mechanical strength and flashover voltage of insulators, forming a huge threat to high‐voltage direct current transmission lines. At present, the parameters of electrolytic corrosion inhibition measures are selected based on the premise of the con...

description Abstract Nowadays, end fitting corrosion reduces the mechanical strength and flashover voltage of insulators, forming a huge threat to high‐voltage direct current transmission lines. At present, the parameters of electrolytic corrosion inhibition measures are selected based on the premise of the constant annual corrosion rate. However, with the development of corrosion, corrosion products accumulate on the insulator surface, which may impact the corrosion rate. In order to clarify the influence of corrosion products, this work studied how corrosion products influence the corrosion rate from the corrosion phenomenon, corrosion current, feature and formation of corrosion products. The results showed that corrosion products of iron and zinc were excellent in adhesion on the insulator surface and could not be cleaned by rain, which was able to increase the corrosion rate. In future, in the selection of the quality of the zinc ring bonded on insulator fittings, there will be a demand to consider the influence of corrosion products on the corrosion rate.
