摘要
为验证高压细水雾系统在通信设备用房的灭火有效性和对日常运维的影响,开展通信设备用房电缆火灾实验,对高压细水雾系统的系统选型、喷头布置、灭火时间、灾后复运等进行研究。在实验间内搭建通信设备用房电缆火灾实验平台,通过开式、闭式高压细水雾系统火灾实验,对灭火时间、火场温度、实验间内氧气浓度、灾后复运、经济适用性展开分析讨论。分析得出,开式、闭式高压细水雾灭火系统均能有效抑制通信设备用房内电缆火灾蔓延。开式高压细水雾灭火系统能够快速灭火,但相较于闭式系统水渍损失较大,而闭式系统则更利于保护区的灾后复运。因此,具体采用何种制式的高压细水雾灭火系统应根据通信设备用房不同安全要求进行合理设计。
In order to verify the fire extinguishing effectiveness of high-pressure water mist system in the communication equipment room and its impact on daily operations and maintenance,system selection,nozzle layout,fire extinguishing time,post-disaster re-transport,etc.for highpressure water mist system are examined through the fire testing for cables in communication equipment rooms.A fire testing platform for cables in communication equipment rooms is built in the laboratory and analysis and discussions are carried out for the fire extinguishing time,fire site temperature,oxygen concentration in the laboratory,post-disaster re-transport,economic applicability,etc.through the fire testing of open and closed high-pressure water mist systems.The analysis shows that both open and closed highpressure water mist fire extinguishing systems can effectively inhibit the spread of cable fire in the communication equipment room.The open high-pressure water mist fire extinguishing system can put out the fire quickly,but the water loss is larger than that of the closed-type system and the closed-type system is more conducive to the post-disaster re-transport of the protection area.Therefore,the specific type of the high-pressure water mist fire extinguishing system to be adopted shall be reasonably designed and selected per the different safety requirements for communication equipment rooms.
