摘要
广州地铁3号线(北延段)非联锁站使用艾默生UHA1R-0050L型小功率UPS,由于单机运行故障率偏高,且无独立维修旁路,无法进行在线维修、更换,为此实施了UPS并机改造,提高了负载设备供电的可靠性。
Emerson UHAIR0050 UPSs are widely used in non-interlocking stations of Guangzhou metro Line 3, or North extension. Due to high rate of failure of single machine of this type of UPS in operation as well as lack of independent maintenance bypass, online maintenance and replacement of the UPS cannot be made. To address this issue, a renovation of UPS parallel opera tion is conducted so as to improve the reliability of power supply of loading equipment and achieves online maintenance and replacement of UPS as well.
