Abstract: The battery pack of the DC distribution cabinet is its backup power supply, which supplies power to the load when the main electricity is interrupted. The battery pack will not be replaced within 5 years after installation and operation. By detecting the voltage and current of the single battery, the faulty battery can be found and replaced in time. Taking Arduino UNO board as the core, this paper designs a single battery voltage and current detection system of DC distribution cabinet, which realizes the effective detection of the single battery voltage and current value of DC distribution cabinet, and solves the potential safety hazard during the operation of DC distribution cabinet.
Keywords: Arduino; DC distribution cabinet; single battery; current detection

空管系统的微波和光端机等通信设备通常采用带蓄电池组的-48 V直流配电柜供电,以保证市电中断时通信设备仍能正常工作。根据最新的供配电设备运行维护管理要求,每季度应对直流配电柜的蓄电池进行1次放电维护,且至少每10分钟应记录1次蓄电池组的总电压以及单体蓄电池的电压和电流值。直流配电柜虽然配置了本地监控模块,但往往只能检测和显示蓄电池组的总电压和负载电流值,不能检测单体蓄电池的电压和电流值;由于没有配置远程监控终端,设备维护人员无法远程获得蓄电池组的状态信息。这不仅无法满足蓄电池的放电维护和远程状态监视需要,还不能及时发现性能下降的蓄电池,存在明显的安全隐患。
本文提出了一种基于Arduino UNO板的直流配电柜单体蓄电池电压和电流检测系统的设计方案,以解决上述安全隐患,保障通信设备的供电安全,供大家参考。……
