As shown in fig. 3, the perfluoro-hexanone fire extinguishing device is installed in an energy storage station, and is connected into a battery box through a spray pipe 15 in a small-volume and multi-bottle group mode. When the temperature in one or more battery boxes reaches a threshold value, glass bubbles in the corresponding battery boxes are broken, signals are transmitted to the fire control controller 12, the perfluorinated hexanone fire extinguishing device is started, and fire extinguishing agents are conveyed to the corresponding battery boxes to spray, so that the fire can be accurately restrained.
