when a fire signal that the temperature change exceeds a set value occurs in the battery room and a fire signal that the smoke concentration or the combustible gas concentration exceeds the set value does not occur at the buildings inside and outside the battery room of the energy storage station, a liquid fire extinguishing method is adopted to immerse the fire extinguishing agent in the battery module with the problem;
when fire signals that the smoke concentration or the combustible gas concentration exceeds a set value appear in buildings outside and inside the battery room of the energy storage station, and fire signals that the temperature change exceeds a set value appear in the battery room, a gas fire extinguishing method is adopted to extinguish the fire of the whole battery room, and meanwhile, a liquid fire extinguishing system is started to immerse fire extinguishing agents for the battery modules with problems;
when extinguishing a fire to a data center station:
when fire signals with temperature change and smoke concentration exceeding a set value simultaneously occur, the electronic equipment is put out a fire by adopting a gas fire extinguishing method after the set delay time.
8. A fire fighting method for a three-station-in-one comprehensive station as claimed in claim 7, characterized in that when fire is extinguished in a transformer substation, a fire signal is sent by a temperature detector or a smoke detector and transmitted to a fire control center, and the fire control center controls an oil discharge and nitrogen injection fire extinguishing system or a gas fire extinguishing system to extinguish the fire.
9. A fire fighting method for a three-station-in-one integrated station as claimed in claim 7, characterized in that when the energy storage station is put out of fire, a fire signal is sent by a smoke detector or a combustible gas detector, or sent by a temperature-sensitive detector, or sent by a smoke detector or a combustible gas detector and simultaneously sent by a temperature-sensitive detector, and transmitted to a fire control center, and the fire control center controls a gas fire extinguishing system and/or a liquid fire extinguishing system to put out fire.
10. A fire fighting method for a three-station-in-one integrated station as defined in claim 7, wherein when fire is extinguished in the data center station, fire signals are simultaneously sent by the temperature detector and the smoke detector and transmitted to the fire control center, and the fire control center controls the gas fire extinguishing system to extinguish the fire.
