摘要
针对绝缘材料在高湿环境及电场作用下易碳化失效的问题,通过改变材料表面憎水性的方法将涂层附着于材料表面,并采用憎水性、附着力及电气试验测试方法,探究不同涂层对片状模塑料(Sheet MoldingCompound,SMC)绝缘材料电气性能的影响。研究发现,室温硫化硅胶(Room Temperature Vulcanized Silicone Rubber,RTV)防污闪涂层能够有效提高SMC绝缘材料在高湿环境下的耐污闪能力和使用寿命,可以在工程上进行应用。
In view of the carbonization failure of insulating materials under high humidity and electric field,the coating is attached to the surface by changing the hydrophobicity,and methods of hydrophobicity,adhesion and electrical test are used to investigate the effect of different coating on the electrical properties of SMC insulating materials.It is found that RTV anti⁃pollution flashover coating can effectively improve the anti⁃pollution flashover resistance and service life of SMC insulating materials in high humidity environment,which can be applied in engineering.
