<p>这个是机房内的设备数量及大概功率,需要8小时供电。厂家给我配的60KS主机,需要192块100ah,12V电池。不知道可行吗,主机和电池够用吗?</p>
<p>谢谢大家</p>

<p>差不多就60KVA,48KW</p>
<p>设:UPS的直流电压=384V(大多数是这个数值),逆变器的效率=0.92,功率因数=0.8&nbsp;&nbsp; </p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 蓄电池的终止电压=1.75V&nbsp; 放电时间8h(一般不会要这么长的时间) N=384/2(计算蓄电池都是以2V单体为数据)</p>
<p>&nbsp;</p>
<p>方法一、蓄电池的放电电流:</p>
<p>&nbsp;I= PN×COSφ×103/(η×V×N )=60*1000*0.8/(0.92*1.75*192)=155 (A)查蓄电池厂家资料:1.75V时,8h的数据</p>
<p>&nbsp;</p>
<p>某一牌子的数据&nbsp;&nbsp;&nbsp; </p>
<p>100Ah&nbsp;&nbsp;&nbsp;&nbsp;12A</p>
<p>125Ah&nbsp;&nbsp;&nbsp;&nbsp;14A</p>
<p>140Ah&nbsp;&nbsp;&nbsp; 16A</p>
<p>160Ah&nbsp;&nbsp;&nbsp; 18A</p>
<p>180Ah&nbsp;&nbsp;&nbsp; 21A</p>
<p>200Ah&nbsp;&nbsp;&nbsp; 23A</p>
<p>&nbsp;</p>
<p>60KVA&nbsp; UPS 的负载功率和后备8小时的时间,至少要300Ah,4组并联才能满足,也就是要4*32=128节的300Ah电池</p>
<p>(注明:但实际上12V是很少或没有300Ah的蓄电池,只能改用6V或2V系列,但成本要上去很多咯)</p>
<p>&nbsp;</p>
<p>方法二、(不建议,没考虑其它因素)</p>
<p>60*1000*0.8/384=125A&nbsp; 也就是放电1小时要125Ah,那8小时*125Ah=1000Ah</p>
<p>但,蓄电池最多只能是4组并联运行</p>
<p>这样就是4组*250Ah,也就是要4*32节的250Ah=128节电池才能满足要</p>
