The anti-pollution flashover coating in a converter station appears rapid hydrophobicity failure phenomenon in a short time after coating, and there is a large domestic winery within 5 kilometers of it, which belongs to a special operating environment. In order to analyze the reasons for the rapid hydrophobicity failure of the anti-pollution flashover coating in this special environment, two groups of anti-pollution flashover coatings were selected and placed in the converter station to conduct simulation tests, and then the hydrophobicity, roughness, and Fourier transform infrared spectroscopy of the two groups of anti-pollution flashover coatings were analyzed in the field and laboratory. The results show that the hydrophobicity of the anti-pollution flashover coating decreases from grade HC1 to grade HC4-HC5 within 7 months. Affected by the surrounding winery environment, the contamination on anti-pollution flashover coating surface in the converter station contains organic substances such as alcohols and phenols, which affects the migration of small molecular siloxanes, leading to the hydrophobicity failure of the anti-pollution flashover coating, while the coating does not show obvious ageing, and its hydrophobicity can be restored immediately after scrubbing the surface dirt.
