摘　　要：室温硫化(RTV)硅橡胶长效防污闪涂料是目前我国电网主要的补救防污闪技术措施。介绍了污闪发生的条件和对策,阐述了RTV涂料的防污闪原理。通过闪络试验得出了结论,适当改进补强剂和添加剂后的新型RTV涂料达到了国家有关的闪络试验要求,具有较好的防污闪性能。Room temperature vulcanizing(RTV) silicone rubber insulator coating is the main remedial method to prevent contamination flashover. It is made from silicone rubber, fillers and additives under special condition. The fillers and additives can strengthen silicone's physical and chemical characteristics. So through adjusting the components of fillers and additives, a new type of RTV coating is reached. Flashover tests on this type of RTV coating have been done. It is concluded that the new type of RTV coating has better capability to prevent contamination flashover than before.
