Perfluorohexanone fire extinguishing method suitable for lithium iron phosphate energy storage battery prefabricated cabin

Abstract

The invention discloses a perfluorohexanone fire extinguishing method suitable for a lithium iron phosphate energy storage battery prefabricated cabin, which takes a battery cluster as a local application protection unit, takes the whole energy storage battery prefabricated cabin as a total flooding fire extinguishing object, and adopts a perfluorohexanone fire extinguishing mode combining local application and total flooding to extinguish open fire in a firing lithium iron phosphate battery. And the thermal runaway is inhibited. The system can effectively extinguish a fire in the energy storage battery cabin and inhibit thermal runaway development, does not cause harm and damage to a protected object, and does not cause secondary disasters; the energy storage battery cabin is protected in a one-control-one mode, the reliability is high, the manufacturing cost is low, the anti-freezing performance is good, and the application range is wide. Meanwhile, the defects in the prior art can be overcome, the fire protection problem of the lithium iron phosphate energy storage battery prefabricated cabin is solved, and large-scale application of the lithium iron phosphate energy storage battery prefabricated cabin can be promoted.

Description
