一、通信電源工作原理

1、電(dian)力通信電(dian)源系統的(de)組(zu)成

電(dian)源是保證(zheng)通信暢通的(de)重要(yao)設備，是通信系統(tong)的(de)重要(yao)組(zu)成部分(fen)。通信電(dian)源系統(tong)主要(yao)有六個部分(fen)組(zu)成：交流配(pei)電(dian)設備、整流器、直流偏大(da)設備、蓄(xu)電(dian)池組(zu)、監控(kong)系統(tong)、防雷接地系統(tong)。

2、電(dian)力通(tong)信(xin)電(dian)源的基本特點和要求

電(dian)(dian)(dian)(dian)力通信(xin)電(dian)(dian)(dian)(dian)源系統是為(wei)了保證電(dian)(dian)(dian)(dian)力系統的(de)可(ke)靠運(yun)行(xing)，尤其是在電(dian)(dian)(dian)(dian)網(wang)事故時保證通信(xin)設備穩定、可(ke)靠、持續(xu)、獨立運(yun)行(xing)，而(er)在通信(xin)機房(fang)設置的(de)直流(liu)專用通信(xin)電(dian)(dian)(dian)(dian)源。對通信(xin)電(dian)(dian)(dian)(dian)源系統的(de)基本要求是可(ke)靠性(xing)與穩定性(xing)。

眾所(suo)周知，一(yi)般(ban)通(tong)信(xin)設備(bei)的(de)故(gu)障只會產(chan)生(sheng)局(ju)部(bu)性的(de)影響(xiang)，而如(ru)果通(tong)信(xin)電(dian)源一(yi)旦發生(sheng)故(gu)障，將(jiang)會造成(cheng)通(tong)信(xin)系統(tong)全部(bu)中斷，產(chan)生(sheng)大范圍的(de)影響(xiang)。因此(ci)電(dian)源系統(tong)交流(liu)部(bu)分應采(cai)用(yong)可靠地(di)市電(dian)來(lai)源，市電(dian)應有兩路輸入(ru)并(bing)能自動切換(huan)，直(zhi)流(liu)部(bu)分應當(dang)采(cai)用(yong)整流(liu)器與電(dian)池(chi)組并(bing)聯浮(fu)充方式(shi)，同時電(dian)源系統(tong)應有防雷(lei)元器件(jian)和防浪涌保(bao)護裝置來(lai)保(bao)證電(dian)源系統(tong)的(de)安全運行。

二、通信電源主要功能有哪些

1、市(shi)(shi)電(dian)(dian)(dian)油機轉換屏：一般在大樓的(de)低壓配(pei)電(dian)(dian)(dian)室，將(jiang)從變(bian)壓器(qi)來百的(de)380V市(shi)(shi)電(dian)(dian)(dian)和油機發電(dian)(dian)(dian)進行切(qie)換，當市(shi)(shi)電(dian)(dian)(dian)中(zhong)斷時啟動油機供(gong)電(dian)(dian)(dian)，是建筑(zhu)物(wu)總的(de)交流電(dian)(dian)(dian)來源。

2、交(jiao)(jiao)流配電(dian)(dian)(dian)屏：交(jiao)(jiao)流輸入，向周邊多路(lu)交(jiao)(jiao)流負載提(ti)供交(jiao)(jiao)流電(dian)(dian)(dian)源，包括(kuo)向高頻開關電(dian)(dian)(dian)源（整流器）提(ti)供交(jiao)(jiao)流電(dian)(dian)(dian)源。

3、高(gao)頻開關電源(yuan)：將輸(shu)入的交流(liu)電轉換成直流(liu)電，輸(shu)出至直流(liu)配電屏(ping)，給(gei)直流(liu)負責提供電源(yuan)。

4、直(zhi)流(liu)(liu)配電(dian)(dian)屏(ping)：負責向周邊二(er)級直(zhi)流(liu)(liu)配電(dian)(dian)設備(bei)度(du)（電(dian)(dian)源(yuan)分(fen)支柜、列(lie)頭柜）提供直(zhi)流(liu)(liu)電(dian)(dian)源(yuan)，以供最終負責使用。同時負責將從高頻(pin)開關(guan)來的直(zhi)流(liu)(liu)電(dian)(dian)輸送(song)至蓄(xu)電(dian)(dian)池(chi)組。當高頻(pin)開關(guan)斷電(dian)(dian)時，將從蓄(xu)電(dian)(dian)池(chi)組來的直(zhi)流(liu)(liu)電(dian)(dian)輸送(song)至負載。

5、蓄電(dian)(dian)(dian)池(chi)組：儲能(neng)設備。高頻開(kai)關工作(zuo)回時(shi)，蓄電(dian)(dian)(dian)池(chi)組負責儲存-48V直流(liu)電(dian)(dian)(dian)電(dian)(dian)(dian)能(neng)；當高頻開(kai)關斷電(dian)(dian)(dian)時(shi)，蓄電(dian)(dian)(dian)池(chi)組負責向負責輸(shu)送電(dian)(dian)(dian)流(liu)。保證(zheng)通信設備不斷電(dian)(dian)(dian)。

6、電源(yuan)分支柜：二級配電設備，負責向機房某個分區配電。

7、列頭柜：二級配(pei)電(dian)(dian)設備，負責向本(ben)列內(nei)的負載(zai)配(pei)電(dian)(dian)供電(dian)(dian)，輸入連(lian)(lian)接自電(dian)(dian)源分(fen)支柜，也可直接連(lian)(lian)接自直流配(pei)電(dian)(dian)屏。

8、UPS：向負載提供交流不間斷(duan)電(dian)源。
