高层建筑火灾自动报警系统电压损失研究

Research on Voltage Losses of Automatic Fire Alarm Systems in High-rise Buildings

简述目前火灾自动报警系统在高速发展的高层建筑中运用的重要性与现状,提出电压损失对火灾自动报警系统的影响。同时,分析火灾自动报警系统中导致电源线路上电压损失的主要因素,并以高层住宅的火灾自动报警系统为例,通过对其电源线路上电压损失的计算和推导,得出在不同供电距离下,怎样更合理地选择电源线,为火灾自动报警系统提供可靠的线路保障。

The significance and current situation of the automatic fire alarm systems used in the fastdeveloping high-rise buildings are introduced briefly,and the influence of the voltage loss on the automatic fire alarm system is proposed. Meanwhile, the main factors for the voltage loss on the power line of the automatic fire alarm system are analyzed, and the measure to choose the power line more reasonably at different power supply distances is summarized by calculating and deducing the voltage losses of the automatic fire alarm systems in the high-rise residences, in order to provide the reliable circuit guarantee for the automatic fire alarm system.
