摘要
蓄电池在供电系统中主要是作为储能设备,当外部交流供电突然中断时,作为系统供电的后备保护,为通信设备的正常工作提供保障。在我站的-48 V直流供电系统中,两组蓄电池组可提供大约40小时的不停电供电电源,在交流不间断供电系统(UPS)中,蓄电池可提供5小时的不间断供电电源,以维持正常的通信。
The battery is mainly used as the energy storage device in the power supply system. When the external AC power supply is suddenly interrupted, the normal communication equipment work is threatened. As a back-up protection system of power supply, two sets of batteries in the48V I system can provide uninterrupted power supply for about 40 hours. And in the AC uninterruptible power system （ UPS）, the battery can provide uninterrupted power supply for 5 hours in order to maintain the normal communication.
