The invention belongs to the technical field of fire extinguishing of energy storage lithium batteries, in particular to an air-cooled energy storage lithium battery cluster-level local application pack precise fire extinguishing system and method, including a perfluorohexanone fire extinguishing box and a fire extinguishing box for controlling the perfluorohexanone The main control module for opening and closing, the output end of the perfluorohexanone fire extinguishing box is fixedly provided with a main conveying pipeline, and the output end of the main conveying pipeline is fixedly provided with a plurality of regional control valves. Cluster-level spraying of fire-extinguishing agent solves the fire safety problem that traditional fire-extinguishing media cannot form effective fire-extinguishing concentration at the fire point in the air-cooled energy storage compartment. An intelligent control system is used to accurately find the fire point, and the fire pack and the cluster where it is located can be integrated as a whole. Spraying, using perfluorohexanone gas to extinguish PACK-level fires, while protecting the entire cluster, can accurately achieve fire-extinguishing protection for PACK-level lithium battery packs, with precise and efficient, regional-level protection, preventing thermal runaway spread and other advantages. |
