在轨道交通中采用集中式不间断电源供电系统(UPS)首先需要考虑哪些系统不宜纳入集中供电系统。设置UPS电源的系统中蓄电池为在线式,负荷由交流电供电。蓄电池为后备式运行,大部分负荷为直流电供电的直流自用系统不宜纳入集中供电系统。应急照明系统需要消防相关认证,也不宜纳入集中供电系统。另外,非在线式的应急电源系统(EPS)也不宜纳入集中供电系统。对于如何整合UPS供电系统,分别根据负荷类型、
In the rail transit using a centralized uninterruptible power supply system (UPS) first need to consider which systems should not be incorporated into the centralized power supply system. Set the system UPS power supply battery is online, the load from the AC power supply. Battery backup operation, most of the load for the DC power supply system should not be included in DC power supply system. Emergency lighting system requires fire-related certification, it should not be included in the centralized power supply system. In addition, off-line emergency power systems (EPS) should not be included in the centralized power supply system. How to integrate UPS power supply system, respectively, according to load type,
