Problems solved by technology
It not only increases the probability of lithium battery failure, but also increases the fire spread channels in the event of a fire, because the circuit between the batteries cannot be cut off.
[0006] (2) Fire hazard of electrical equipment
The way of using water to extinguish the fire requires continuous spraying for a long time, otherwise the heat will flow back quickly, and the remaining active substances will still be ignited. The requirements for water p

The invention discloses an energy storage battery compartment fire extinguishing system which comprises a prefabricated compartment. A plurality of energy storage battery boxes are arranged in the prefabricated compartment, fire detectors are arranged in the energy storage battery boxes, and the fire detectors are electrically connected with the signal input end of a fire alarm controller; and thesignal output end of the fire alarm controller is connected with a gas fire extinguishing system and a water mist fire extinguishing system. A fire extinguishing method of the energy storage batterycompartment fire extinguishing system comprises the following steps that the type of a fire occurring in the energy storage battery boxes is judged according to a detection result of the fire detectors, specifically, when the fire type is an electrical fire, the gas fire extinguishing system is started to extinguish open fire, and then the water mist fire extinguishing system is started to cool; and when the fire type is a battery fire, the water mist fire extinguishing system is started to extinguish the fire and cool. According to different characteristics of battery and electrical fires, the fire can be found in time and different action strategies can be adopted, fire development is restrained to the maximum extent, and losses are reduced to the minimum.
Description
technical field [0001] The invention relates to a fire-fighting system for an energy storage battery compartment and a fire-extinguishing method thereof, belonging to the technical field of substation fire-fighting automation control. Background technique [0002] In recent years, my country's energy storage technology has developed rapidly, and more and more large-scale energy storage lithium battery cabins are used in power systems. The fire hazard of lithium battery energy storage system mainly includes two aspects: the fire hazard of lithium battery and the fire hazard of electrical equipment. [0003] (1) Fire hazard of lithium batteries [0004] The study found that the fire involving lithium batteries is mainly the result of electrolyte decomposition and combustion, which is a hydrocarbon gas combustion fire. The National Fire Protection Association (NFPA) pointed out in a study on lithium battery combustion fires that the fire hazard of lithium batteries mainly com...
