特殊工业粉尘地区绝缘子超疏水涂层应用效果研究

Effect of super-hydrophobic coating in special industrial dust area

超疏水涂层具备优异的憎水性及自清洁性,因此在防污闪领域具备广阔的应用前景。为了研究超疏水涂层在特殊工业粉尘地区的应用效果,选取国内某企业提供的超疏水涂层,利用超疏水涂层绝缘子及同型号的无涂层复合绝缘子在江苏响水县开展了挂网运行测试,通过污秽度测试、憎水性测试及微观测试分析了超疏水涂层的积污性能、老化性能及涂层对硅橡胶的保护性能。结果显示,超疏水涂层绝缘子相比普通硅橡胶绝缘子,表面积污量减少约37%。尽管运行10个月后,超疏水涂层出现了老化,但涂层对内部硅橡胶材料起到了较好的保护作用,有效预防了内部材料的老化。

The super-hydrophobic coating has excellent hydrophobicity and self-cleaning property.Therefore,it has a broad application prospect in the field of anti-pollution flashover.In order to study the application effects of superhydrophobic coating in special industrial dust area,the super-hydrophobic coating provided by a domestic enterprise is selected,and the super-hydrophobic coating insulator and the same type of uncoated composite insulator are used in Xiangshui,Jiangsu Province.The contamination accumulation characteristics of the super-hydrophobic coating,the aging properties of coating and the protective performance of the coating to silicone rubber are analyzed through the contamination level test,hydrophobicity test and microscopic test.The results show that the surface contamination amount of super-hydrophobic coating insulator is reduced by 37%compared with ordinary silicone rubber insulator.Although the super-hydrophobic coating ages after running for 10 months,the coating plays a good protective role on the internal silicone rubber material and effectively prevents the internal material from aging.
