【摘要】：输电线路用室温硫化硅橡胶涂料因其优良的憎水性和憎水迁移性,可有效保护线路以防污闪事故的发生。但随着近年来环境的变化、雾霾天气的增多,目前所使用的室温硫化硅橡胶涂层因憎水性丧失而导致的闪络事故大大增加,造成极大经济损失。文章从防污闪涂料组分和结构出发,分析了涂料憎水性、憎水迁移性和附着力等性能特点,指出了现有研究的不足。结合国内外防污闪涂料的研究进展,指出可以通过改善室温硫化硅橡胶的基底材料、成分、构造类荷叶超疏水结构等方法,开发一种新型长效防污闪涂料,是提高外绝缘可靠性的有效方法和发展方向。
[Abstract]:Because of its excellent hydrophobicity and hydrophobicity, room temperature vulcanized silicone rubber coating for transmission lines can effectively protect the transmission lines from pollution flashover accidents. However, with the change of environment and the increase of haze weather in recent years, the flashover accidents caused by the loss of hydrophobicity of the room temperature vulcanized silicone rubber coatings used at present have greatly increased, resulting in great economic losses. Based on the composition and structure of the anti-pollution flashover coating, this paper analyzes the properties of the coating, such as its hydrophobicity, hydrophobicity and adhesion, and points out the shortcomings of the existing research. Combined with the research progress of anti-pollution flashover coating at home and abroad, it is pointed out that a new kind of long-acting anti-pollution flashover coating can be developed by improving the substrate material, composition of room temperature vulcanized silicone rubber and constructing superhydrophobic structure of lotus leaf. It is an effective method and developing direction to improve the reliability of external insulation.
