摘　　要：储能电站火灾事故频发,其消防安全问题日益突出。为验证模组级、全淹没级全氟己酮灭火系统对液冷型磷酸铁锂储能预制舱火灾(火灾突破至电池箱外)的抑制性能,设计液冷型磷酸铁锂储能预制舱全氟己酮火灾抑制装置。基于实际储能电柜和预制舱尺寸建立火灾模型,分析全氟己酮火灾抑制装置(模组级、全淹没级)对液冷型磷酸铁锂储能预制舱火灾的抑制效果。结果表明,两种抑制装置均可以在抑制介质开始喷放后8 s内扑灭明火,且30 min内不发生复燃。Fire accidents occur frequently in energy storage power stations,and their fire safety problems are becoming increasingly prominent.To verify the suppression performance of pack level and full submergednce level perfluorohexanone extinguishing systems on liquid-cooled lithium iron phosphate energy storage prefabricated chamber fires(i.e.,fires spreading outside the battery box),a reliable perfluorohexanone fire suppression device for liquid-cooled lithium iron phosphate energy storage prefabricated cabin was designed.A fire model was established based on the actual size of the energy storage cabinet and prefabricated cabin,and analysis was conducted to determine the suppression effect of pack level and full submergence level perfluorohexanone fire suppression device on liquid-cooled lithium iron phosphate energy storage prefabricated cabin fires.The results showed that both these suppression devices could extinguish open flames within 8 seconds after injection,without reignition for up to 30 minutes.
