1存在问题传统的UPS在工作时,一面通过外部电源向内部电池组充电,同时也要向计算机或其他设备进行供电。所有的电池组对于UPS系统来说是一个整体,当其中的某一块电池发生故障后,UPS不能对它进行及时的关闭和替换,只能发出系统故障指示,然后需手工进行更换。如果未能及时更换和修复,就会发生电力供应的中断。在更换电池时,需关闭UPS,由UPS支持的系统也需要暂停。
1 Problems A traditional UPS charges the internal battery pack with external power while it is working, as well as supplying power to a computer or other device. All of the battery packs are integral to the UPS system. When one of the batteries fails, the UPS can not shut it down and replace it in time. It can only issue system fault indications and then need to be replaced manually. If it fails to be replaced and repaired in time, there will be an interruption of the electricity supply. The UPS needs to be shut down when replacing the battery and the system supported by the UPS also needs to be suspended.
