摘　　要：架空输电线路导线在服役过程中经常会受到覆冰影响,引发安全事故,我国是发生输电线路覆冰事故较多的国家之一,为此针对架空导线开展抗结冰工作对保障电力系统安全运行具有重要意义。利用废旧硅橡胶复合绝缘子伞裙制备一种超疏水粉末,与环氧树脂按一定比例喷涂在玻璃基底上制备超疏水表面,其水接触角可达154°。将制备的粉末喷涂在钢芯铝绞线表面上,对其自清洁、抗结冰及表面耐久性进行测试。研究结果表明:在低温环境下具有硅橡胶粉末/环氧树脂超疏水涂层的导线相比原始导线具有更好的抗结冰性能,在相同环境温度下,相同时间内其结冰量只有原始导线的一半,可以有效延缓结冰,且在光照、腐蚀、反复除冰的环境下,也具有抗冰耐久性。该制备方法简单可行、效率高,能实现废旧材料的循环利用,可进一步应用于生产实践。The wires of overhead transmission lines are often affected by icing during use,leading to safety accidents.China is one of the countries with more icing accidents on transmission lines.Therefore,the anti-icing work for overhead wires is of great significance to ensure the safe operation of the power system.A kind of super-hydrophobic powder is prepared by using waste silicone rubber composite insulator skirt.The powder and epoxy resin are sprayed on a glass substrate in a certain proportion to prepare a super-hydrophobic surface with a contact angle of 154°with water.The prepared powder is sprayed on the surface of the steel core aluminum stranded wire to test its self-cleaning property,anti-icing property and surface durability.The research results show that the wire with silicone rubber powder/epoxy resin superhydrophobic coating has better anti-icing performance than the original wire in low temperature environment.Under the same ambient temperature and the same time,the amount of icing is only half of the original wire,which can effectively delay icing,and it also has anti-icing durability under the environment of light,corrosion,and repeated deicing.The preparation method is simple,feasible and efficient,and the recycling of waste materials is realized.The research results can be further applied to production practice.
