摘要
直流系统由充电单元对蓄电池进行充电的同时并向经常性负载如继电保护装置、控制设备等提供直流电源。当控制负荷或动力负荷需较大的冲击电流如断路器分、合闸时,由充电单元和蓄电池共同提供直流电源。
The DC system charges the batteries by charging units and provides DC power supply to the regular loads such as relay protection devices and control equipment. When the control load or power load requires large impulse current,such as circuit breaker opening and closing,the charging unit and the battery provide DC power supply together.
