防蓄电池开路自动跨接预警装置研究与应用
摘要
文中讨论了由于蓄电池不宜长时间储存
更换周期长
导致部分内阻高、容量低的劣化电池被迫长时间运行
交流失电时会造成直流母线失压的这种情况。针对这种情况
本文提出一种防蓄电池开路自动跨接预警装置
可长期在线运行
满足劣化电池运行期间监测预警
又能保证蓄电池组能在交流停电时正常供电。
Abstract
This paper discusses that some batteries with high internal resistance and poor capacity may cause"internal open circuit"after running for a long time because it will take a long time from purchase to replacement due to the unfavorable storage of batteries. AC voltage loss may cause serious harm to DC bus voltage. In this case
an automatic crossing connection and warning device for preventing battery open circuit is proposed
which can run on-line for a long time to meet the need of long replacement cycle and ensure that the battery can supply power normally when AC power is cut off.
