摘要
介绍不断电更换UPS的理论方法和实际经验,利用UPS内部的静态开关实现旁路与输出之间的同期,再用检修旁路替代UPS给负荷供电,在不间断供电的情况下更换新的UPS。另外,还提出了提高UPS供电可靠性和检修便利性的措施。
The theoretical method and practical experience of uninterruptible power supply(UPS)replacement Under Uninterupted Power Supply are introduced.By using the static switch inside the UPS to realize the synchronization between the bypass and the output,thus the bypass can supply power for the load instead of th eU P S,then UPS can be replaced under uninterrupted power supply.In addition?measures were put forward to improve the reliability of UPS power supply and the convenience of maintenance.
