摘　　要：随着网络技术的快速发展,越来越多的数据机房采用分布式电源(DPS)机房。而由于DPS机房内存在磷酸铁锂电池,导致DPS机房火灾特点区别于传统以电缆为主的数据机房火灾,因此应对DPS机房磷酸铁锂电池火灾展开试验研究。重点试验研究了DPS机房磷酸铁锂过充火灾下的探测系统报警及高压细水雾系统灭火效果、可燃气体浓度研究,并对比了高压细水雾系统不同布置方式下的灭火效果,给出了探测系统设计意见,从而为工程项目应用提供技术支撑。With the rapid development of network technology,more and more dater centers are adopted distributed power supply rooms which are named by DPS rooms for short.Due to the presence of lithium iron phosphate batteries in the DPS room,the fire characteristics in the DPS computer room are different from traditional cable fires.Therefore,experimental research should be conducted on lithium iron phosphate battery fires in the DPS room.The article focuses on experimental research on the detection system and high pressure water mist system extinguishing effect and combustible gas concentration under the overcharging fire for lithium iron phosphate battery in the DPS room.It also compares the fire extinguishing effect of the high pressure water mist system under different design methods,and provides design suggestion for the detection system,which will provide technical support for the application of engineering projects.
