摘要
信号系统是城市轨道交通的重要组成部分,是控制列车安全运行的系统,其对供电系统的稳定性和可靠性要求极高。信号系统的电源设备包括智能电源屏(含稳压器)、不间断电源系统(Uninterruptable Power System,UPS)设备以及蓄电池组等,通过该套电源系统可以向信号系统室内设备和室外设备提供不间断的稳定电源。结合大连地铁信号系统实际情况,详细分析智能电源屏和UPS的组成与工作原理,并对信号电源系统的配置方案进行探讨,为进一步提高信号设备电源系统维护水平提供理论指导。
Signal system is an important part of urban rail transit,and it is the system to control the safe operation of trains.The stability and reliability of its power supply system are very high.The power supply equipment of signal system includes intelligent power supply panel(including voltage regulator),UPS and storage battery.Through the power supply system,it provides uninterruptible,stable and clean power supply for indoor and outdoor equipment of signal system.In this paper,combined with the actual situation of Dalian Metro signal system,the composition and working principle of intelligent power supply panel and ups are analyzed in detail,and the configuration scheme of signal power supply system is discussed,so as to provide theoretical guidance for further improving the maintenance level of signal equipment power supply system.
