摘要
介绍了PBD系列不间断电源屏与直流操作电源,共同组成电力系统的专用UPS,向电力系统通讯、监控保护设备、事故照明及其他不能停电的设备提供电力。并指出从变电站现有的直流屏上取电,就不必像常规不间断电源(UPS)那样增设庞大而昂贵的蓄电池组,从而避免蓄电池组的重复投资,减少系统的维护,降低系统运行成本。
The paper introduces a series of uninterruptible power supply panel with PBD DC operating power, a common component of power system dedicated UPS, to the power system communication, monitoring and protection equipment, emer- gency lighting and other devices can not provide electricity blackouts. Pointed out that the existing DC panel from the sub- station to take power on, you do not like the conventional uninterruptible power supply （UPS） as an additional large and ex- pensive battery, battery pack in order to avoid duplication of investment, reduce system maintenance and reduce system oper- ating costs.
