Study Notes
直流系统正常运行方式
- 系统由两组蓄电池组成，采用高频开关整流模块，单母分段运行，且每个模块内部具有监控功能。
- 蓄电池组的充电装置由两路互为备用的交流电源供电，当一路断电时，另一路会自动投入。
- 当三相交流电源恢复后，充电装置能自启动，自动按电池事故放电容量和单体电池端电压，选择相应的充电方式。
运行注意事项
直流系统操作
- 蓄电池组投入或退出运行时应遵循蓄电池先并后退的原则。
- 退出蓄电池时宜采用同时退出本段充电装置的模式。
充电装置投入和退出步骤
- 充电机投入运行步骤：
- 合上交流输入电源空开
- 逐个开启高频整流充电模块
- 检查微机监控单元模块运行是否正常
- 合上充电机输出总开关
- 合上蓄电池组开关
- 充电机退出运行步骤：
- 检查充电装置的充电电压是否一致
- 断开蓄电池组开关
- 断开充电机输出总开关
- 逐个关停高频整流充电模块
- 断开充电机交流输入电源空开
蓄电池组投入和退出运行的操作
- 蓄电池组一般情况下与相应的充电机一同投退，不允许充电机在不带蓄电池组的情况下单独运行。
- 蓄电池组单独退出时，应先检查对比充电机的直流母线电压（电压差小于1.5V，否则应先调整电压），再断开蓄电池组开关，并取下蓄电池组总出口熔断器。
- 当蓄电池组总出口熔断器熔断时，应立即检查对比充电机的直流母线电压（电压差小于1.5V，否则应先调整电压）。
