1、可靠性

要求各種電源設(she)(she)(she)備、各種開關、轉換開關和其他(ta)的配電設(she)(she)(she)備必(bi)須(xu)非常可靠，具(ju)有很高(gao)的平(ping)均無故障時(shi)間(jian)指標。在設(she)(she)(she)計通信電源系(xi)統時(shi)力(li)求簡單，采取(qu)消(xiao)除(chu)或減少(shao)單點故障的設(she)(she)(she)計方法。

2、功能性

要求(qiu)各(ge)種電(dian)(dian)源設備(bei)必須能穩定供電(dian)(dian)，各(ge)項輸出指標滿(man)足質量(liang)要求(qiu)。供電(dian)(dian)電(dian)(dian)壓(ya)(ya)過(guo)高(gao)會引起(qi)通(tong)(tong)(tong)信(xin)(xin)負載(zai)設備(bei)元器件損壞(huai)，供電(dian)(dian)電(dian)(dian)壓(ya)(ya)過(guo)低又會影響通(tong)(tong)(tong)信(xin)(xin)系統的正常運行。直(zhi)流供電(dian)(dian)系統的衡重雜(za)音電(dian)(dian)壓(ya)(ya)過(guo)高(gao)會影響電(dian)(dian)話(hua)通(tong)(tong)(tong)話(hua)質量(liang)；脈動(dong)電(dian)(dian)壓(ya)(ya)過(guo)高(gao)會使(shi)數據(ju)通(tong)(tong)(tong)信(xin)(xin)設備(bei)的誤碼率增(zeng)加(jia)。UPS交(jiao)流不間斷電(dian)(dian)源應能抑(yi)制市(shi)電(dian)(dian)電(dian)(dian)源的各(ge)種干(gan)擾，干(gan)擾可能引起(qi)互聯網傳輸速率下降(jiang)、數據(ju)丟失(shi)等，甚至導(dao)致網絡癱瘓。

3、可維修性

通(tong)信(xin)電(dian)(dian)(dian)源(yuan)系(xi)(xi)統的設計必須使所有電(dian)(dian)(dian)源(yuan)系(xi)(xi)統元(yuan)件能夠在通(tong)信(xin)系(xi)(xi)統正常供(gong)電(dian)(dian)(dian)的情況下進行維護(hu)，一般稱為“同時(shi)(shi)維護(hu)”，即(ji)通(tong)信(xin)電(dian)(dian)(dian)源(yuan)系(xi)(xi)統的一部分(fen)設備在正常運行的同時(shi)(shi)對另(ling)一部分(fen)電(dian)(dian)(dian)源(yuan)設備進行維護(hu)。

4、故障容限

通信電(dian)(dian)源(yuan)系統(tong)必須具有抗(kang)故障的能(neng)力，做到(dao)電(dian)(dian)源(yuan)系統(tong)的任何元件出現故障都(dou)不會影響正常供電(dian)(dian)和通信負載設(she)備的正常運行，而且整個配電(dian)(dian)系統(tong)也必須有抗(kang)故障的能(neng)力，從(cong)而可(ke)以彌補不可(ke)避免的負載故障和人為操作錯(cuo)誤造成的影響。
