Hz的市电范围,关于零压开关的问题在后面还要进行讨论,这里是两台发电机分别向两台计算机供电,第三台电机G8备用(空转),当两台电机吼和如运行正常时,指示灯Lz亮,有一台输出电压不正常,比如电压有故障,控制器马上就测量出来了,切断Sll-S18的控制信号而同时给S81-S38加上控制信号进行换机,更换电机后指示灯灭、L81亮,表明G8代替了仔GB代替Gi的情况也如此,并且当S不正常时仍可换接回来.如果电压没有故障,属于正常换机维护,只需扳一下(或按一下)换机扭子开关(或按钮)就可以了.当然,可以把电子开关与接触器联合使用这样可减小体积和功耗,即换机时用电子开关,换接过程完后,将接触器或闸刀合上,以旁蹄电子开关,欲要换机时,先扳断接触器或闸刀,不过利用热管技术散热,其体积比同容量的接触器大不了多少.就这样利用上述的电子开关换接技术,把维修时间MTTR从可靠性公式中剔除了.在某种程度上实现了交流不间断供电的要求,为交流供电系统的故障强度与维修率,但由于在直流与交流系统中都把维修时间MTTR减至零,所以Po也就?了.这样,一个由DOHRS与类UPS构成的供电系统稳定,怎样实现的同步输出就可有把握地保证计算机在所规定的工作时间内不会因供电系统故障而停机了?/p><p
