1、可靠(kao)性

要(yao)求各(ge)種(zhong)電源設(she)(she)備(bei)、各(ge)種(zhong)開關、轉換開關和其他的配(pei)電設(she)(she)備(bei)必(bi)須(xu)非常可靠，具有(you)很高的平均無故(gu)障時間指標。在(zai)設(she)(she)計通信電源系統(tong)時力求簡單，采取消除或減少單點故(gu)障的設(she)(she)計方法。

2、功能性

要(yao)求(qiu)各種電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)設(she)備(bei)必須能(neng)穩定(ding)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，各項(xiang)輸出指標滿足質(zhi)(zhi)量要(yao)求(qiu)。供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過(guo)高會引起(qi)通(tong)(tong)信(xin)(xin)負載設(she)備(bei)元器件(jian)損壞，供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過(guo)低又會影響(xiang)通(tong)(tong)信(xin)(xin)系統的正常運行。直流(liu)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系統的衡重雜音電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過(guo)高會影響(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)話通(tong)(tong)話質(zhi)(zhi)量；脈動電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過(guo)高會使(shi)數據通(tong)(tong)信(xin)(xin)設(she)備(bei)的誤碼率增加。UPS交流(liu)不間(jian)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)應(ying)能(neng)抑制市電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的各種干擾(rao)，干擾(rao)可能(neng)引起(qi)互(hu)聯網傳輸速率下降、數據丟失等(deng)，甚至導致(zhi)網絡癱瘓(huan)。

3、可維修性

通(tong)信電(dian)源(yuan)(yuan)系統(tong)的設計必須使(shi)所有(you)電(dian)源(yuan)(yuan)系統(tong)元件(jian)能(neng)夠(gou)在通(tong)信系統(tong)正(zheng)常供電(dian)的情況(kuang)下進行(xing)維(wei)護，一(yi)般(ban)稱為(wei)“同時維(wei)護”，即通(tong)信電(dian)源(yuan)(yuan)系統(tong)的一(yi)部分(fen)設備在正(zheng)常運行(xing)的同時對另一(yi)部分(fen)電(dian)源(yuan)(yuan)設備進行(xing)維(wei)護。

4、故障容限

通信電源系統必須(xu)具(ju)有(you)抗故障(zhang)的(de)能力，做到電源系統的(de)任何元(yuan)件出現(xian)故障(zhang)都(dou)不會影(ying)響(xiang)正(zheng)常(chang)供電和通信負(fu)載設備的(de)正(zheng)常(chang)運行，而且整(zheng)個配電系統也(ye)必須(xu)有(you)抗故障(zhang)的(de)能力，從(cong)而可(ke)以彌補(bu)不可(ke)避免的(de)負(fu)載故障(zhang)和人為操作(zuo)錯誤造成的(de)影(ying)響(xiang)。
