摘要
为研究电动汽车充换电站火灾发生时火灾发展、烟气蔓延、温度变化及CO分布情况,设计具有自动控制、实时监测、数据采集、显示、探测报警、数据存储等功能的充换电站火灾模拟燃烧试验平台,并进行燃烧试验。通过燃烧不同材料,分别模拟站内监控室、充换电室及配电室等3种典型火灾场景的燃烧。根据现场实时监测、记录的燃烧过程数据,分析电动汽车充换电站火灾蔓延规律及其危险性。结果表明:配电室的烟气蔓延速度、CO体积分数上升速度及其最高值均高于监控室及充换电室的相应值。因此,配电室火灾危险性最大;监控室材料易被引燃,危险性居中;充换电室内的电池燃烧释放烟气少,危险性最小。
To know the fire development,smoke spreading,temperature variation and CO distribution when a fire breaks out in an electric vehicle charging and swapping station,a simulated fire experiment platform was designed and established,which had functions of autocontrol,real-time monitoring,data acquisition,displaying,detection alarming,and data storage. Combustion experiments were carried out for the monitoring room,the charging and swapping room,and the distribution by burning different materials.The results show that the most dangerous place in the station is the distribution room because the speed of smoke spreading and concentration rising rate of CO and the maximum concentration of CO in it are higher than those in the monitoring,charging and swapping rooms. The charging and swapping room has the lowest fire danger,and the monitoring room has a middle fire danger.
