随着电力系统的快速发展,电力系统的消防安全日益重要。为加快电力设备火灾响应时间,提高灭火效率,研制了一种基于全氟己酮灭火剂的微型颗粒温感灭火绳。全氟己酮是一种清洁、高效的灭火剂,且绝缘强度高,适合进行电力设备火灾的扑救,是哈龙材料的理想替代物。对全氟己酮进行优化,减少其对电力设备的腐蚀性,作为灭火绳的芯材。利用温敏材料、氧化剂、固化剂等材料制作灭火绳的壁材,对全氟己酮灭火剂进行固化,制得微型灭火颗粒,粒径为50～400μm。将芯材、壁材装入绳状载体中,制得触发温度为115℃,灭火时间为3.5s的微型颗粒温感灭火绳。该灭火绳可安装于各类电力设备机构箱内,极大缩短灭火时间,保障电力系统稳定运行,具有较高的使用价值和广阔的市场空间。
With the rapid development of power systems,fire safety in power systems has become increasingly important.Novec 1230 is a clean and efficient fire extinguishing agent with high dielectric strength,making it suitable for extinguishing fires in electrical equipment and an ideal substitute for halon materials.To accelerate the response time to fires in electrical equipment and improve fire extinguishing efficiency,this paper developed a micro-particulate temperature-sensitive fire extinguishing rope based on Novec 1230 fire suppressant.The optimization of Novec 1230 reduced its corrosiveness to electrical equipment and served as the core material of the fire extinguishing rope.Using temperature-sensitive materials,oxidizers,curing agents,and other materials to create the shell material of the fire extinguishing rope,the Novec 1230 fire suppressant was solidified to produce micro fire-extinguishing particles with a particle size of 50～400μm.By loading the core material and shell material into a rope-like carrier,a micro-particle temperature-sensitive fire extinguishing rope with a triggering temperature of 115℃ and a fire extinguishing time of 3.5s was manufactured.This fire extinguishing rope could be installed in various types of electrical equipment enclosures,greatly reducing the fire extinguishing time and ensuring the stable operation of power systems,and offering high practical value and broad market prospects.
