没人顶.自己顶一下

tsjy2009 发表于 2009-5-17 21:50:00

<p>&nbsp;&nbsp;&nbsp; 如果是UPS100%满载，后备时间20小时，很准确，如果负载UPS50%，后备时间2小时，差不多。</p>
<p>&nbsp;&nbsp;&nbsp; 这是因为电池的AH数是在20小时放电速率定义的，比如100AH电池，用5A的电流放电可以放20小时，即5X20=100AH。只要放电电流大于5A（以100AH为例）就达不到标称容量。如以100A的放电速率放电大约可以放电30分钟。即只能达到标称容量的50%。当然这是质量比较好的电池，有的电池在大电流放电时连这个时间也达不到。</p>
<p>&nbsp;&nbsp;&nbsp; 另一方面UPS很少有满载的，大多都在50-60%负载，所以说按方法2估算也凑和了。好象许多UPS经销商都按方法1估算，包括APC的服务人员。</p>

<p>学习了~~~谢谢楼主~~基本上平时用的都是第一个</p>
<p>&nbsp;</p>
<p>PS：请教楼主，第二个的功率因数和逆变器效率是机器标注的么？</p>

tsjy2009 发表于 2009-5-19 21:07:00

<p>功率因数是估的，0.7左右，没人能搞的准。2KVA以上UPS的逆变器效率在90%以上可以去查产品的规格书。</p>

ksyr 发表于 2009-5-21 10:26:00

<p>功率因数一般用0.7</p>

tiandiren555 发表于 2009-5-23 08:16:00

不太会算，有没有简单的工式

zcheng_lee 发表于 2009-5-25 22:04:00

<p>第一种方法比较简单</p>

<p>学习下</p>

虽然这块做的不多也了解一下

电池组放电终止电压V是多少？算出的电池AH数是指总电池组的容量吗？如果是又要怎么选择用单台多少AH的电池？

<div class="quote"><b>以下是引用<i>icejo</i>在2009-5-26 16:38:00的发言：</b><br/>电池组放电终止电压V是多少？算出的电池AH数是指总电池组的容量吗？如果是又要怎么选择用单台多少AH的电池？ </div>
<p>算出来的不是电池组的总容量，是电池组中一节的容量！其实第一个公式，比较通用，算出来和第二个公式差别不大，不信你们都可以试一试！如果觉得第一个公式有不妥，可以考虑再乘1.1的系数，就一定OK了！</p>

学习学习

cys890 发表于 2009-6-2 00:52:00

厉害

weizi0906 发表于 2009-6-9 14:22:00

<p>看来还挺复杂</p>
<p>&nbsp;</p>

zcheng_lee 发表于 2010-4-4 14:58:00

<p>自己也要多看看,不然自己都会忘记!还是有一定用处的!</p>

yinggw 发表于 2010-4-6 11:16:00

算好电池的功率后，查电池厂家的电池数据功率表就可以得到须符合电池的型号或容量了
