摘要
从分析UPS电源装置架构入手,确定在UPS系统中中性导体的作用及中性导体中断的影响,由此分析判断在UPS系统中如何选择双电源转换开关,以防因开关选择错误而造成系统故障。
The roles of neutral conductors and the impacts of interruption of neutral conductors in UPS systems are determined on the basis of analyzing the structure of a UPS system,and conclusions are drawn on how to select a dual power switch to prevent system failures due to incorrect selection of switch in a UPS system.
