摘　　要：大连地铁通信共有14个子系统,电源系统是14个子系统之一,它的主要作用是为通信设备在市电断电之后提供后备电源。通过调查了解,大连地铁通信电源系统提供后备2小时的供电,基本满足在市电断电后由蓄电池为通信系统提供电源保障。同理,信号电源系统也非常重要,虽然相对于通信电源来说信号电源系统的后备时间不长,但是对于维持基本的信号设备运行有很大的帮助。基于此,以大连地铁通信、信号电源系统为调查对象,结合电源系统的日常维护内容,详细探讨大连地铁通信电源系统、信号电源系统的日常维护,从而为后续进一步提升地铁电源系统维护水平奠定理论基础。Dalian Subway communication has a total of 14 subsystems,and the power supply system is one of the 14 subsystems.Its main function is to provide backup power for communication equipment after the mains is cut off.Through investigation,it is found that the communication power supply system of Dalian Subway provides a 2-hour backup power supply,which basically satisfies the need for the battery to provide power supply for the communication system after the mains power is cut off.In the same way,the signal power system is also very important.Although the backup time of the signal power system is not long compared with the communication power supply,it is of great help to maintain the operation of the basic signal equipment.Based on this,taking Dalian subway communication and signal power system as the investigation objects,combined with the daily maintenance content of power system,the daily maintenance of Dalian subway communication power system and signal power system is discussed in detail,so as to lay a theory for further improving the maintenance level of subway power system in the future.
