1、可靠性(xing)

要求各(ge)種電源設(she)備、各(ge)種開(kai)關(guan)(guan)、轉換(huan)開(kai)關(guan)(guan)和其他的(de)配電設(she)備必須非常可靠(kao)，具有很高的(de)平均無故(gu)障時間指標。在設(she)計通信電源系統時力求簡單，采取(qu)消(xiao)除或減少單點(dian)故(gu)障的(de)設(she)計方法(fa)。

2、功能性

要(yao)求各種電(dian)(dian)(dian)(dian)(dian)(dian)源設(she)(she)備必須(xu)能穩定(ding)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，各項輸出指(zhi)標滿(man)足質(zhi)量要(yao)求。供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過高(gao)會(hui)引(yin)起通(tong)信(xin)(xin)負載(zai)設(she)(she)備元器(qi)件損壞，供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過低又會(hui)影響通(tong)信(xin)(xin)系(xi)(xi)統的正常運行。直流供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統的衡重(zhong)雜音電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過高(gao)會(hui)影響電(dian)(dian)(dian)(dian)(dian)(dian)話通(tong)話質(zhi)量；脈(mo)動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過高(gao)會(hui)使數據(ju)通(tong)信(xin)(xin)設(she)(she)備的誤碼率(lv)增(zeng)加。UPS交流不間斷電(dian)(dian)(dian)(dian)(dian)(dian)源應能抑制市電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源的各種干擾，干擾可能引(yin)起互(hu)聯網傳輸速率(lv)下(xia)降、數據(ju)丟失等(deng)，甚至導(dao)致網絡癱瘓。

3、可維修性

通信電源系統的(de)(de)設(she)計必須使所有(you)電源系統元件能(neng)夠(gou)在通信系統正常供電的(de)(de)情況下(xia)進行維護，一般稱為“同時維護”，即通信電源系統的(de)(de)一部分(fen)設(she)備在正常運行的(de)(de)同時對另一部分(fen)電源設(she)備進行維護。

4、故障容限

通(tong)信(xin)電(dian)源系統必(bi)須具有抗故(gu)障的(de)(de)(de)(de)能(neng)力，做到電(dian)源系統的(de)(de)(de)(de)任何元件出現故(gu)障都不會(hui)影(ying)響正常供(gong)電(dian)和通(tong)信(xin)負載(zai)設備的(de)(de)(de)(de)正常運(yun)行，而且整個配(pei)電(dian)系統也必(bi)須有抗故(gu)障的(de)(de)(de)(de)能(neng)力，從而可以彌(mi)補(bu)不可避(bi)免的(de)(de)(de)(de)負載(zai)故(gu)障和人(ren)為操作錯誤(wu)造(zao)成的(de)(de)(de)(de)影(ying)響。
