UPS配电系统设计

摘要

分析了不间断电源（UPS ）的供电特点，介绍了UPS容量及输入、输出配电系统的相关计算方法。指出UPS 在选择负载时，需考虑功率因数匹配的问题，再根据负荷性质和供电要求确定 UPS 容量及工作方式，以保证设备安全、稳定运行。%This paper analyzed the power supply characteristics of UPS.The related calculation methods of UPS capacity and input and output currents of power distribution system were introduced.It is pointed out that the matching problem of power factor is considered when the loads are selected,and according to the load character and power supply requirement,the UPS capacity and operating modes are determined to ensure the safe and steady state operation of devices.
