| 摘 要： | 在说明通信局（站）电源系统对VRLA蓄电池组可靠性要求的基础上，阐述了为了达到电信设备的电压、电流需求，通过串联或串并联构成电池组的单体VRLA蓄电池应达到的可靠性指标。在确定单体VRLA蓄电池应达到的可靠性指标。在确定单体VRLA蓄电池可靠性参数时，可通过现场使用调查或加速寿命试验的办法来求得。在单体VRLA蓄电池可靠性指标过低的情况下，可通过多种冗余连接方式来提高电池组的可靠性。

| Abstract: | Based on the requirements of telecommunication station(site)power supply system on VRLA battery reliability,it expounds the reliability index of VRLA battery cell,which are in serial or series and parallel to meet the demand on voltage and current of telecommunication equipment.Reliability parameters of VRLA battery cell may be gotten by on-the-spot application investigation and accelerated life testing.Reliability of battery can be improved by kinds of redundant connection approaches when VRLA battery cell's reliability index is too small. |
