超高层建筑电气火灾自动报警系统设计探讨

Discussion about Design of Automatic Fire Alarm System in Extra-high Buildings

分析电气火灾发生的原因,阐述线型光纤感温火灾探测系统的原理及功能,提出在超高层建筑电缆竖井、电缆梯架、计算机室的活动地板下等易发生电气火灾的部位设置线型光纤感温火灾探测系统,可以及早发现并处理火灾事故。结合实际工程设计,介绍线型光纤感温火灾探测系统在超高层建筑工程中的应用。对规范有关消防联动的规定进行探讨,提出消防联动切断非消防电源时应注意的问题。

Based on analysis on causes of electrical fire and description of principles and functions of linear fiber-optic temperature fire detection system, it is recommended to install linear fiber-optic temperature fire detection system in cable shaft, cable ladder and raised floor under computer room of extra-high buildings where electrical fire may occur easily, so as to detect fire and take effective measures timely. In combination with actual engineering design, the application of such system to extra-high buildings is introduced. Additionally, provisions on fire control linkage under relevant specification are discussed and problems to be noted when the non-fire power is cut off through fire control linkage are presented.
