怎样算延时

已知UPS是40K的三进单出机子，蓄电池的容量是12V100AH，节数是16节，求电池的延时时间！这个是怎样算的呢？

输出电压多少伏

makel83 发表于 2010-4-3 19:19:00

理论上满载的话是0.48小时，半载的话再乘2就行了。这么算自己想吧。这可是我的心得

楼主请参考，附件的xls文件是我自己做的，工作表一计算放电电流，工作表二查延时时间。希望对你有帮助。
 
UPS外接电池组延时时间计算方法 
1.       等额功率算法 
单个蓄电池电压(V) × AH数 × 电池个数 = 负载功率(W) × 延时时间
（实际负载W转换为VA:服务器等设备一般功率因素是0.8，即容量10000VA的UPS其负载功率就是10000 × 0.8 = 8000W) 
优点：计算简单
缺点：计算结果不精确（主要是由于计算中没有考虑到电池容量和放电电流的关系。相同电池容量下，放电电流越大，电池放出的总功率越小。 
2.    计算放电电流法 
计算放电电流的公式是： 放电电流=UPS容量(VA) × 负载功率因素 / (逆变器效率 × UPS终止电压) 
以山特10KVA为例： UPS容量：10KVA UPS输出功率因素：0.8 UPS终止电压：单只电池终了电压×UPS电池组电池个数=10.5V×16只=168VDC 逆变器效率：0.85 注意：电池的能量并非都能直接提供给负载，它还包含了把电池能量转换 为负载可使用的能量的转换效率，即逆变器效率。 
放电电流=10000VA X 0.8 /(0.85 × 168)V = 56A 
然后根据计算结果查阅蓄电池放电电流表
