摘要
Abstract
To effectively reduce icing accidents of insulators, a super-hydrophobic coating with lotus morphology is made for insulators by chemically depositing nano-particles layer on the surface of hydrophobic material. The coating surface is of lotus-like micro-nano binary roughness structure, which makes the contact angle of water reach to (160±0.5)°. Two isoceles triangle glass plates with respective super-hydrophobic coating and RTV coating, as well as one blank isoceles triangle glass plate, are put into the artificial climate chamber for icing. After one hour icing period, the leakage current test and ultraviolet imaging test are conducted on the three samples under 20 kV voltage. The results indicate that the super-hydrophobic coating can apparently slow icing process, decrease ice quantity, and form a unique ice surface composed of small and separated ice particles in early icing stage to prevent formation of continuous ice layer, which makes the leakage current much smaller than that of other two samples on which continuous ice layers already form in early icing stage. Therefore, the sample with super-hydrophobic coating exhibits better performances in leakage current and ultraviolet imaging tests, compared with other two samples.关键词
