群集中的所有硬件有2个或3个电源输入,则要求至少有三个独立的电路,以确保群集的电路设计中没有单点故障。发电机能把机械能转换成电能,干电池能把化学能转换成电能。发电机、电池本身并不带电,它的两极分别有正负电荷,由正负电荷产生电压(电流是电荷在电压的作用下定向移动而形成的),电荷导体里本来就有,要产生电流只需要加上电压即可,当电池两极接上导体时为了产生电流而把正负电荷释放出去,当电荷散尽时,也就荷尽流(压)消了。

什么是过功率保护?
答:除了额定功率之外,还有一个数据,叫“过载保护”,英文叫“OPP”。过载保护指电源的负载持续上升,达到某个点了,电源就自动断电,以免出现过流损坏电源或者电脑的其他部件。OPP值通常是额定功率的1.3倍左右,有些厂商把OPP设得太高,其实是不的。在额定功率和OPP之间,会有一个区间,比如,新冷钻额定功率300W,OPP为370W,那么,300-370W之间的这个区域就是一个“盲区”。如果在这个区间停留的时间过长(一般可以持续数十秒时间),很可能导致电源或电脑的其他部件烧毁。
