组合电源配电系统的构成 组合电源配电系统包括交流配电、直流配电、系统防雷、配电系统数据采样及接口等。交流配电单元将交流电送入整流模块,整流模块采用并联工作方式,模块的直流输出经汇流排接入直流配电单元,直流配电单元包括两路后备电池输入和多路直流输出。 针对雷电及过电压的危害,中兴电源在系统上采取三级防雷措施。在组合电源系统柜的外部(即交流线由室外进入机房的入口处)安装有交流配电系统的第一级防雷,在组合电源的内部安装有交流配电系统的第二级防雷,第三级防雷安装在整流模块的内部。根据我国电网的实际情况,防雷器在系统中按TT方式连接。
Combination of power distribution system composition Power distribution system includes AC distribution, DC distribution, lightning protection systems, power distribution system data sampling and interface. The AC power distribution unit feeds the AC power to the rectifier module. The rectifier module adopts the parallel working mode. The DC output of the module is connected to the DC power distribution unit through the busbar. The DC power distribution unit includes two backup battery inputs and multiple DC outputs. For the dangers of lightning and over-voltage, ZTE power system to take three lightning protection measures. In the outside of the combined power system cabinet (ie AC line from the outside into the room at the entrance) is equipped with AC power distribution system of the first level of lightning protection in the combined power supply installed AC power distribution system of the second stage lightning protection, Lightning protection installed in the rectifier module within the third. According to the actual situation of China’s power grid, lightning protection device in the system by TT way to connect.
