1、可(ke)靠性

要求各種電源設(she)備(bei)、各種開(kai)關(guan)、轉換開(kai)關(guan)和其他的(de)配(pei)電設(she)備(bei)必須非常可(ke)靠，具有很高的(de)平均無故障(zhang)(zhang)時間(jian)指標。在設(she)計(ji)通(tong)信電源系統時力求簡(jian)單，采取消除或減少(shao)單點故障(zhang)(zhang)的(de)設(she)計(ji)方(fang)法。

2、功能性

要(yao)求(qiu)各(ge)種(zhong)電(dian)(dian)(dian)源設(she)備必(bi)須能穩定供(gong)電(dian)(dian)(dian)，各(ge)項(xiang)輸出指標滿足(zu)質量要(yao)求(qiu)。供(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)過(guo)高會引起通信(xin)負(fu)載設(she)備元器件損壞(huai)，供(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)過(guo)低又會影(ying)響(xiang)(xiang)通信(xin)系統的正常運行。直流供(gong)電(dian)(dian)(dian)系統的衡重雜(za)音電(dian)(dian)(dian)壓(ya)過(guo)高會影(ying)響(xiang)(xiang)電(dian)(dian)(dian)話通話質量；脈動電(dian)(dian)(dian)壓(ya)過(guo)高會使數據通信(xin)設(she)備的誤碼(ma)率(lv)增加。UPS交流不(bu)間斷(duan)電(dian)(dian)(dian)源應能抑制市電(dian)(dian)(dian)電(dian)(dian)(dian)源的各(ge)種(zhong)干(gan)(gan)擾(rao)，干(gan)(gan)擾(rao)可能引起互聯網傳輸速率(lv)下降、數據丟失等(deng)，甚至導致(zhi)網絡癱瘓。

3、可維修性

通信電(dian)源(yuan)系(xi)(xi)統(tong)(tong)的(de)(de)設計(ji)必須使所有電(dian)源(yuan)系(xi)(xi)統(tong)(tong)元件能夠(gou)在(zai)(zai)通信系(xi)(xi)統(tong)(tong)正常供(gong)電(dian)的(de)(de)情(qing)況下進(jin)行(xing)維護(hu)，一般稱為“同時維護(hu)”，即通信電(dian)源(yuan)系(xi)(xi)統(tong)(tong)的(de)(de)一部分(fen)設備(bei)在(zai)(zai)正常運行(xing)的(de)(de)同時對另一部分(fen)電(dian)源(yuan)設備(bei)進(jin)行(xing)維護(hu)。

4、故障容限

通(tong)(tong)信電(dian)(dian)源(yuan)系(xi)(xi)統必須(xu)具(ju)有抗(kang)故(gu)(gu)障(zhang)的(de)(de)(de)能(neng)力，做(zuo)到(dao)電(dian)(dian)源(yuan)系(xi)(xi)統的(de)(de)(de)任何元件(jian)出現故(gu)(gu)障(zhang)都不會(hui)影(ying)響正(zheng)常(chang)供電(dian)(dian)和(he)通(tong)(tong)信負(fu)載設備的(de)(de)(de)正(zheng)常(chang)運(yun)行，而且整個配電(dian)(dian)系(xi)(xi)統也必須(xu)有抗(kang)故(gu)(gu)障(zhang)的(de)(de)(de)能(neng)力，從(cong)而可以彌補不可避(bi)免的(de)(de)(de)負(fu)載故(gu)(gu)障(zhang)和(he)人為操作錯(cuo)誤造(zao)成(cheng)的(de)(de)(de)影(ying)響。
