基于并机冗余式UPS的双总线供电系统分析和应用

空管五类关键设备要求极高的设备完好率和正常率,供电设备更是被列入一类保障,负载要求UPS供电输出必须做到万无一失。采用双总线的UPS并机冗余系统供电后,航管中心的各类设备均处于稳定供电网络的后级或末端,双总线结构下,结合空管系统重要设备配置应急小型UPS的要求,即可轻易实现设备运行高稳定供电保障。

The five key devices of ATC(air traffic control)require that there be very high rate of equipment integrity and normal rate.The power supply equipment is also included in the first class guarantee,whose load requires that UPS power supply output must be foolproof.With power supply by Dual bus UPS parallel machine redundancy system,various types of equipment in the ATC center are in a stable back or end of the power supply network,and with the dual bus structure,in accordance with the requirements of small UPS ATC system of important equipment emergency,high-stability power supply equipment operation can be easily achieved.
