市电油机切换间隔UPS电池充放电性能分析

Analysis of Charging and Discharging Performance of UPS Battery at Switching Interval between Mains and Generator

从一起通信大楼高压线路年度例行检修测试时出现的市电油机切换操作引起UPS输出掉电故障案例着手,分析市电油机切换操作中UPS电池充放电性能,提出了市电油机切换的时间间隔高于30 min的要求,对保障通信大楼安全、可靠、稳定供电具有重要作用。

Starting from a case of UPS output power failure caused by the switching operation of the mains oil generator during the annual routine maintenance test of the high-voltage line of the communication building,the charging and discharging performance of the UPS battery during the mains oil generator switching operation is analyzed,and the mains oil generator switching operation is proposed.The time interval is higher than the requirement of 30 minutes,which plays an important role in ensuring the safe,reliable and stable power supply of the communication building.
