摘要
输电线路的覆冰灾害是电力系统最严重的威胁之一。超疏水绝缘涂层具有强憎水性和低表面能,因而具有提高输电线路防覆冰与防污性能的潜力。对超疏水绝缘涂层的制备方法及其在电力系统中的应用研究现状进行概述,介绍超疏水绝缘涂层的电绝缘性、化学稳定性、机械稳定性等基本性能,对比分析超疏水绝缘涂层与普通憎水性绝缘涂层的防覆冰与防污性能,阐明超疏水绝缘涂层在延缓绝缘子覆冰方面的机理。此外,对超疏水绝缘涂层在耐腐蚀等领域的应用研究现状也进行了介绍。提出在未来输电线路超疏水绝缘涂层的研究中,应重点关注制备方法的经济性、涂层表面的长效性以及防污闪机理等方面的关键问题,提升涂层的综合性能。
Icing disaster is one of the most serious threats to the security and stability of power system.With many excellent properties such as low wettability and low surface energy,super hydrophobic insulation coatings can improve the anti-icing and anti-pollution performance of transmission lines effectively.In this paper,the current research of super hydrophobic coatings in power system including preparation and application is summarized.The basic properties of superhydrophobic insulating coatings are introduced,such as electrical insulation,chemical stability and mechanical property.Compared with other common coatings,the mechanism of super hydrophobic coatings in delaying the icing of insulators is expounded,indicating that the hydrophobic coating has good anti-icing and anti-pollution performance.In addition,the application of super hydrophobic coatings in the field of corrosion protection is also introduced.Finally,the issues about future research on super hydrophobic coatings are raised.In order to improve comprehensive performance of the coating,it is important to focus on the economy of the preparation method,the long-term performance of the surface and the mechanism of anti-pollution flashover.
