地铁车站中EPS电源应用的若干问题

Some Problems of EPS Power Supply Application in Subway Station

我国社会经济的快速发展,城市交通压力的增加使得地铁作为一种新的便捷客运交通方式受到越来越多人们出行的首选。地铁的完善在一定程度上缓解了城市交通压力,同时也提高了交通运输效率。但需要注意的是,地铁属于地下建筑,地下人员呈现为密集且错综分布的特点,若发生紧急电力故障则需要依靠紧急照明。地铁车站应急照明作为一级负荷,当车站出现灾害或者外部电源故障等情况时,可有效地确保人员的安全紧急疏散。因此,除了安装一级负荷配置双电源外还需设置电源EPS,当供电中断无照明电源后仍可通过EPS供电疏导人员,进而确保人们生命财产安全。鉴于此,对EPS电源系统及工作原理进行简要阐述,并在此基础上探讨当前EPS电源在地铁车站应用中存在的问题。

With the rapid development of China’s social economy and the increase of urban traffic pressure,subway,as a new and convenient means of passenger transportation,has become the first choice for more and more people to travel.The improvement of subway alleviates the urban traffic pressure to a certain extent,and also improves the traffic efficiency.However,it should be noted that the subway is an underground building with dense and intricate distribution of underground personnel.In case of emergency power failure,emergency lighting is required.Subway station emergency lighting as a level 1 load,when the station appeared adverse situations such as disasters or power failure,emergency lighting can effectively ensure the safety of the personnel emergency evacuation,so in addition to install with double power supplies also need to pay ha configuration Settings EPS power supply,so that when the power outage no policy after lighting power supply still can through EPS guidance personnel,to ensure that people life and property safety.In view of this,it briefly describes the EPS power supply system and its working principle,and on this basis,discusses the problems existing in the current application of EPS power supply in subway stations.
