基于火灾下地铁人员疏散的电气系统设计研究

Research on Electrical System Design of Subway Evacuation in Case of Fire

随着社会和时代的发展,城市交通系统中地铁运输的优势越来越明显。由于其独特的建筑结构和操作环境,车站起火的后果非常严重。为了防止大规模破坏的发生,特别是有效防止和减少火灾受害者的方法,地铁设计要着重参考该情境。地铁安全避难设施十分重要,当地铁上的所有乘客都要到一个安全的地方避难时,消防队员们也要马上进入车站进行灭火作战和营救。从火灾疏离人群的角度出发,主要围绕应急照明设定模式、常规照明除去模式、自动火灾报警系统设计为主等几个方面进行论述,结合一些实际的案例使电气系统在地铁火灾救灾的过程更加具体。

With the development of society and times,the advantages of subway transportation in urban transportation system are becoming more and more obvious.Due to its unique building structure and operating environment,the consequences of station fire are very serious.In order to prevent the occurrence of large-scale destruction,and especially to prevent and reduce fire victims effectively,the subway design should focus on this situation.Subway safety refuge facilities are very important.When all passengers on the subway have to take refuge in a safe place,firefighters should also enter the station immediately for firefighting and rescue.From the perspective of fire alienating people,this paper mainly discusses the setting mode of emergency lighting,the removal mode of conventional lighting and the design of automatic fire alarm system.Combined with some practical cases,this paper makes the process of electrical system in subway fire disaster relief more specific.
