摘　　要：对地铁通信系统的UPS(不间断电源)系统的工作方式、特点进行了阐述,并对由于接线不良造成的典型故障的现象、原因加以说明分析。在对UPS故障排查过程中,应根据电路原理对故障进行详细分析,不应简单地更换损坏元件后随意开机而造成二次损坏;应认真检查、测试引起故障的元器件的各项技术参数,避免故障处理过程中不必要的损失。The working method and characteristics of metro communication UPS are elaborated, the typical fault caused by poor wiring is studied. In the investigation process, the UPS fault shall be analyzed based on the circuit principle, not by way of simpe replac of the breakdown elements to prevent the second damage, all the technical parameters of the breakdown elements shall be checked out carefully to ensure no further losses happening.
