New breakthrough in energy storage safety: full analysis of fire protection system

The following is a detailed introduction to these three types of energy storage container fire protection system, hoping to provide readers with some help. Total Flooding Fire Extinguishing System This system mainly consists of fire extinguishing devices, detection systems, and extinguishing agent delivery piping. In the choice of extinguishing device, sevofluoropropane fire extinguishing system is favored for its fast response capability to lithium battery fire in closed environment, and experiments have proved that it can effectively prevent re-ignition. In addition, ultrafine dry powder and carbon dioxide are also common choices, the former can quickly extinguish the fire without rekindling, while the latter can quickly extinguish the fire but there is a risk of rekindling. Perfluorohexanone is an emerging option, and although it does not cause rekindling in confined environments, its use in total flooding systems is less common because certification is not yet fully open. In contrast, the use of perfluorohexanone in cluster-level extinguishing systems is more common. Through the above introduction, it is not difficult to find that, when choosing a suitable fire protection system for energy storage containers, we should not only consider its extinguishing efficiency and anti-reignition ability, but also consider environmental factors and safety certification and other factors. Water, as the most common extinguishing medium for lithium battery fires, has an incomparable cooling effect. In some well-designed power exchange stations, we can see a special facility - pool. When the lithium battery thermal runaway phenomenon, this device can quickly move the battery to the pool, the fastest speed to control the fire, and for some cases that do not facilitate the movement of the battery, such as energy storage containers, the designer will usually be in the gas fire extinguishing system outside the additional sprinkler system, to ensure that nothing is wrong. When it comes to monitoring system, for the characteristics of lithium battery storage containers, we will use a variety of detection technology for all-round monitoring. These include temperature detectors, smoke detectors, and combustible gas, carbon monoxide and hydrogen detectors. These devices can sense the occurrence of fire and activate the preset fire extinguishing program in time, which greatly enhances the safety factor. In terms of extinguishing agent transmission, pipe network Heptafluoropropane is the preferred option for energy storage container fire protection systems. The electrical area is clearly separated from the energy storage area through specially designed pipes, and different extinguishing devices are used to ensure safety. The electrical area utilizes suspended fire extinguishers, while the energy storage area relies on a networked Heptafluoropropane system. With carefully laid out nozzles, it is possible to ensure that the extinguishing agent is evenly distributed throughout the protected area. However, there are also some designs with safety hazards, for example, the electrical area and the energy storage area share a common pipe network Heptafluoropropane system. Considering that Heptafluoropropane can have a toxic reaction at certain concentrations, this design can easily reach dangerous concentrations during rapid leakage and spray release. A time delay feature is usually provided on the system mainframe panel. By default, the activation time from the detection of a fire alarm signal to the start of automatic water spraying is set to 30 seconds. This time can be adjusted according to actual needs. The main purpose of the delay setting is to allow sufficient time for evacuation and also to prevent unnecessary damage caused by false alarms. In some specific situations, such as energy storage containers where space is small and fire spreads quickly, it is recommended that the delay time be reduced to 10 seconds or even less to allow for a quick response.
