1、可靠性(xing)

要求各(ge)種電源設(she)備、各(ge)種開關、轉(zhuan)換開關和其他的(de)(de)(de)配(pei)電設(she)備必須非(fei)常可(ke)靠，具有很高的(de)(de)(de)平(ping)均(jun)無故障(zhang)時間指標。在設(she)計(ji)通信電源系統(tong)時力求簡(jian)單，采(cai)取(qu)消除或減少(shao)單點(dian)故障(zhang)的(de)(de)(de)設(she)計(ji)方法。

2、功能性

要求各種電(dian)(dian)(dian)(dian)(dian)(dian)源設(she)備必(bi)須能(neng)(neng)穩定供電(dian)(dian)(dian)(dian)(dian)(dian)，各項(xiang)輸(shu)出指標滿足(zu)質量要求。供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過(guo)高會(hui)引(yin)(yin)起(qi)通信(xin)(xin)負載設(she)備元(yuan)器(qi)件損壞，供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過(guo)低又(you)會(hui)影響(xiang)(xiang)通信(xin)(xin)系(xi)統的正常(chang)運行(xing)。直流供電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統的衡重雜音(yin)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過(guo)高會(hui)影響(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)話通話質量；脈(mo)動電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過(guo)高會(hui)使(shi)數據通信(xin)(xin)設(she)備的誤碼(ma)率(lv)增加(jia)。UPS交(jiao)流不間斷電(dian)(dian)(dian)(dian)(dian)(dian)源應能(neng)(neng)抑制市電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源的各種干(gan)擾(rao)，干(gan)擾(rao)可能(neng)(neng)引(yin)(yin)起(qi)互聯網傳輸(shu)速率(lv)下(xia)降、數據丟失等，甚至(zhi)導致(zhi)網絡癱瘓。

3、可維修性

通信電(dian)(dian)(dian)(dian)源系(xi)(xi)統的(de)設計必須使所有電(dian)(dian)(dian)(dian)源系(xi)(xi)統元件(jian)能夠在通信系(xi)(xi)統正(zheng)常供電(dian)(dian)(dian)(dian)的(de)情(qing)況(kuang)下進(jin)行維護(hu)，一般稱為“同時維護(hu)”，即通信電(dian)(dian)(dian)(dian)源系(xi)(xi)統的(de)一部分設備在正(zheng)常運行的(de)同時對另(ling)一部分電(dian)(dian)(dian)(dian)源設備進(jin)行維護(hu)。

4、故障容限

通(tong)(tong)信電(dian)源(yuan)系統必須具有抗故(gu)障(zhang)的(de)能(neng)力(li)，做(zuo)到電(dian)源(yuan)系統的(de)任何元件出現故(gu)障(zhang)都(dou)不會(hui)影(ying)響正常供電(dian)和通(tong)(tong)信負(fu)載設(she)備的(de)正常運行，而且整(zheng)個配電(dian)系統也必須有抗故(gu)障(zhang)的(de)能(neng)力(li)，從而可(ke)以彌(mi)補不可(ke)避(bi)免的(de)負(fu)載故(gu)障(zhang)和人為(wei)操作錯誤造成的(de)影(ying)響。
