Description
Technical Field
The invention relates to an energy storage battery compartment fire-fighting system and a fire-fighting method thereof, belonging to the technical field of substation fire-fighting automatic control.
Background
In recent years, the energy storage technology in China is rapidly developed, and more large energy storage lithium battery compartments are applied to power systems. The fire hazard of the lithium battery energy storage system mainly comprises two aspects of the fire hazard of a lithium battery, the fire hazard of electrical equipment and the like.
Fire hazard of lithium battery
It has been found that a fire involving lithium batteries is mainly a hydrocarbon gas burning fire as a result of decomposition and combustion of the electrolyte. The american fire protection association (NFPA) has pointed out in research directed to lithium battery fire fires: the fire hazard of lithium batteries arises primarily from their construction and is directly related to the material composition of the battery. Under the condition of abuse, factors such as battery overheating, excessive charge and discharge, battery design defects, short circuit caused by raw material defects and the like can cause chemical reaction among battery materials in the lithium battery, electrolyte is decomposed, and a large amount of heat and gas are generated, so that thermal runaway of the battery is caused. The research suggests that the thermal runaway which releases energy rapidly is the main cause of electrolyte combustion, and once the thermal runaway occurs, the temperature of the battery rises rapidly, which directly causes the combustion of battery materials. When the concentration of combustible gas generated by decomposition and combustion of the lithium battery electrolyte reaches a certain degree, explosion can occur when exposed fire occurs.
In a large lithium battery energy storage system, the battery pack has the characteristics of high density and centralized distribution, the lithium battery modules are connected in series to form a single battery pack, and the plurality of battery packs are connected in parallel to form a high-capacity energy storage unit. The probability of faults of the lithium batteries is increased, and once a fire disaster occurs, the circuit cannot be cut off between the batteries, so that a fire spreading channel is increased.
(II) fire hazard of Electrical Equipment
The presence of a large number of ancillary electrical devices in a lithium battery energy storage system increases the overall fire risk of the energy storage system due to unsafe use of such devices. When unexpected high voltage and large current (thunder and lightning and surge) invade, the lithium battery energy storage system is invaded by instantaneous high voltage and large current, and fire disasters are easy to happen. On one hand, because the electronic equipment in the lithium battery energy storage system is highly integrated, the resistance capability of the lithium battery energy storage system to high voltage and large current is reduced; on the other hand, the number of communication lines used in the system is large, and channels for high voltage and large current are also increased. Meanwhile, the failure of the protection element is also one of the important causes of fire.
(III) hazards of energy-storage engineering fire
In general, lithium batteries generate a large amount of gas during combustion, and mainly include organic gases such as hydrogen, carbon monoxide, carbon dioxide, methane, benzene, and toluene, and toxic gases such as hydrogen chloride and hydrogen fluoride. The lithium battery energy storage system is generally installed near main equipment of a transformer substation, and once a fire disaster occurs, combustible gases such as hydrogen, carbon monoxide and the like released by a lithium battery in an energy storage battery box under the high-temperature condition cannot be effectively controlled, so that the fire is easy to rapidly spread, even explode, the main electrical equipment is endangered, and further huge property loss is caused.
The fire-fighting device equipped with the existing lithium battery energy storage system mainly extinguishes fire through water or gas. The adoption of water fire extinguishing requires long-time continuous spraying, otherwise, heat can quickly flow back, residual active substances can still be ignited, the requirements on water pressure and water quantity are high, and fire extinguishing cannot be realized by completely depending on the water fire extinguishing mode. The gas fire extinguishing mode is adopted, the fire extinguishing agent conveying distance is short, the fire extinguishing agent cost is high, acid gas can be generated in the fire extinguishing process, the fire extinguishing agent is harmful to human bodies, and the fire can not be extinguished completely by the gas fire extinguishing mode.
