解读高层建筑二级负荷消防设备设计

1、解读高层建筑二级负荷消防设备设计In terpretati on of the high-risebuildi ng fire equipme nt sec on dary loaddesig n高层修建依据其运用性质、火灾风险司长、分散和补救难度等进 行分类。1O- 18层住所应属二类高层修建。其间首要通道和楼梯间照明用电、客梯用电、排污泵和日子水泵用电为二级负荷，其消防用 电负荷：消防操控室、火灾主动报警及联动操控设备以及阀门等用电 应为二级负荷。High-rise buildi ng accord ing to the use of n ature, fire risk, directo
