地铁复合式屏蔽门系统火灾特性分析

Fire Characteristics of Metro Composite Platform Screen Door System

复合式屏蔽门系统是在全封闭屏蔽门的上方安装组合式电动风阀,并接入车站机电控制系统。当站台发生火灾时,该系统可根据火灾发生在站台端部还是站台中部,有针对性地启动不同火灾模式,既能解决传统站台排烟方案对新规范的适应性问题,也能有效解决一直以来站台中部楼扶梯口排烟困难的问题。通过各地不同类型的车站实测得出,排烟效果较为理想,可以供其他城市借鉴。

The composite platform screen door system is equipped with a combined electric damper above the fully enclosed platform screen door and is connected to the electromechanical control system of the station. When a fire occurs on the platform, the system can start different fire modes according to whether the fire occurs at the end or middle of the platform;this not only solves the problem of adapting the traditional platform smoke exhaust scheme to the new norm but also effectively address the difficulty of exhausting smoke at the escalator at the middle of the platform. Through the actual measurement of different types of stations, the smoke exhaust is effective and can be used as a reference by other cities.
