摘要
旨在制备适合复合绝缘子的光热涂料以解决其冬季覆冰问题。测量了光热涂层吸收率与发射率,分析了光热涂层融冰过程,建立光热型复合绝缘子融冰模型,并对其温升情况进行仿真;进行了带电融冰试验,探究不同太阳光照强度及环境温度对光热涂层融冰效果的影响。仿真及人工模拟试验结果表明:该光热型融冰涂料具有良好的光热性能;涂覆光热涂层的复合绝缘子具有一定的融冰效果,融冰效果随太阳光照强度与环境温度的升高而加强。
This paper introduces the photothermal coating suitable for composite insulators to address icing in winter.The absorptivity and emissivity of photo-thermal coatings are measured.Based on the analysis of the melting process of the photothermal coating,the melting model is established for the photothermal composite insulator,and the temperature rise is simulated.The electrified ice melting test is conducted to explore the influence of different sunlight intensity and ambient temperature on the ice melting effect of the photo-thermal coating.The results show that the photo thermal ice melting coating introduced in the paper has good photo thermal properties.The composite insulator coated with the photothermal coating has a certain degree of ice melting effect,and the ice melting effect is enhanced with the increase of sunlight intensity and ambient temperature.
