    Abstract:The characteristics of different types of UPS and the main electrical functions of isolation transformer are expounded,the necessity of the inverter and isolation transformer of power-frequency UPS is analyzed,and the rationality of the isolation transformers at different point locations on the power path of UPS is compared. A configuration scheme for the isolation transformers of UPS is recommended based on the typical application and common problems in the electrical design of civil architecture.
    Key words:uninterrupted power supply (UPS);power-frequency UPS;high-frequency UPS,isolation transformer;single-input UPS system;double -input UPS       system;single-input UPS system without bypass;common-mode voltage
 
    摘 要:阐述不同类型UPS的特性和隔离变压器的主要电气作用,分析工频UPS逆变器隔离变压器的必要性,对比UPS功率路径上不同点位设置隔离变压器的合理性。结合民用建筑电气设计中典型应用及常见问题,推荐UPS隔离变压器配置方案。
