摘要： 为研究高压细水雾对轨道交通枢纽站设备用房电缆火灾的保护效果，采用实体试验的方法，建立了轨道交通枢纽站设备用房全尺寸试验模型，阐述了细水雾灭火机理、主要设计参数、系统选型。结果表明：预作用式高压细水雾能够有效抑制电缆火燃烧，阻止电缆火在水平方向上的蔓延；细水雾施加一段时间后，试验环境温度恢复至25 ℃左右，且施加细水雾后氧气体积分数变化幅度较小，最低为20.62%，不会对人体造成伤害；预作用式细水雾系统能够减少水渍损失。

Abstract: Abstract: In order to study the protective effect of high pressure water mist on cable fire in equipment room of rail transit hub station, a full?scale test model of equipment room of rail transit hub station was established by using the method of entity experiment, and the fire extinguishing mechanism, main design parameters and system selection were expounded. The results show that the pre?acting high?pressure water mist can effectively restrain the cable fire combustion and prevent the cable fire from spreading in the horizontal direction. After the application of fine water mist for a period of time, the ambient temperature of the test was restored to about 25 ℃, and the change range of oxygen volume fraction after the application of fine water mist was small, the lowest was 20.62%, which would not cause harm to human body. Pre?acting water mist system can reduce water damage.
