一、通信電源用了什么新技術

隨著移動(dong)通信(xin)業的不(bu)斷發展壯大(da)，對(dui)通信(xin)電(dian)源的要求也越(yue)來(lai)越(yue)高(gao)(gao)。傳(chuan)統的通信(xin)電(dian)源由于某(mou)些(xie)方面存在一系列不(bu)足，已不(bu)能滿足新的需要。新技(ji)術(shu)的應(ying)用可以有(you)效(xiao)優化通信(xin)電(dian)源的性(xing)能，提高(gao)(gao)電(dian)源的可靠(kao)性(xing)和穩定性(xing)，從而滿足更(geng)加廣泛的應(ying)用需求。

1、燃料電池技術

燃料電池技術是一種新型的電力技術，逐漸被廣泛應用于通信電源中(zhong)(zhong)。燃(ran)(ran)料(liao)電(dian)池(chi)可以將化學能(neng)(neng)轉換為(wei)電(dian)能(neng)(neng)，為(wei)通信設(she)備(bei)供應電(dian)能(neng)(neng)，從(cong)而(er)能(neng)(neng)夠為(wei)通信系統提(ti)供長時(shi)(shi)間的電(dian)力支持(chi)，同(tong)時(shi)(shi)還能(neng)(neng)夠減少對環(huan)境的污(wu)染。目前(qian)，燃(ran)(ran)料(liao)電(dian)池(chi)技術的發展主要集(ji)中(zhong)(zhong)在(zai)兩個(ge)方面(mian)：燃(ran)(ran)料(liao)電(dian)池(chi)的低(di)(di)溫(wen)化和燃(ran)(ran)料(liao)電(dian)池(chi)的中(zhong)(zhong)高溫(wen)化。低(di)(di)溫(wen)燃(ran)(ran)料(liao)電(dian)池(chi)具(ju)有(you)響應快、環(huan)境適應能(neng)(neng)力強(qiang)等(deng)優勢(shi)；而(er)中(zhong)(zhong)高溫(wen)燃(ran)(ran)料(liao)電(dian)池(chi)則具(ju)有(you)高效(xiao)、連續(xu)穩(wen)定工作等(deng)特點。燃(ran)(ran)料(liao)電(dian)池(chi)的應用，不(bu)僅在(zai)通信電(dian)源領域，也(ye)用于其他(ta)領域。

2、太陽能技術

在通信電源中，太陽能技術被廣泛應用。太陽能技術在環保、安全等方面具有明顯的優勢，可以有效解決傳統的通信電源存在的一系列問題。太陽能電池的(de)(de)(de)穩(wen)定性(xing)(xing)不(bu)斷提(ti)高(gao)，但也(ye)存在不(bu)可(ke)忽視的(de)(de)(de)缺點(dian)，如夜(ye)間或天氣惡劣時無法提(ti)供足夠的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)。為了解決(jue)這些(xie)問(wen)題，通(tong)信電(dian)(dian)(dian)(dian)(dian)源(yuan)逐漸采取多種電(dian)(dian)(dian)(dian)(dian)源(yuan)設備的(de)(de)(de)結(jie)合方式，例如太(tai)陽(yang)能與(yu)(yu)蓄電(dian)(dian)(dian)(dian)(dian)池、交流(liu)電(dian)(dian)(dian)(dian)(dian)供電(dian)(dian)(dian)(dian)(dian)等共同使用。隨著通(tong)信電(dian)(dian)(dian)(dian)(dian)源(yuan)產(chan)業的(de)(de)(de)發(fa)展(zhan)，對電(dian)(dian)(dian)(dian)(dian)源(yuan)系統的(de)(de)(de)要求(qiu)也(ye)越來越高(gao)。為了增強(qiang)系統備份時間和(he)穩(wen)定性(xing)(xing)，通(tong)信電(dian)(dian)(dian)(dian)(dian)源(yuan)在本地儲能技(ji)術上取得了很(hen)大的(de)(de)(de)進展(zhan)，成(cheng)為重要的(de)(de)(de)技(ji)術趨勢。在過(guo)去，燃(ran)料(liao)電(dian)(dian)(dian)(dian)(dian)池和(he)太(tai)陽(yang)能電(dian)(dian)(dian)(dian)(dian)池都(dou)是利用儲存電(dian)(dian)(dian)(dian)(dian)荷來產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)力。但是，由于燃(ran)料(liao)電(dian)(dian)(dian)(dian)(dian)池和(he)太(tai)陽(yang)能電(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)特殊性(xing)(xing)質，一旦電(dian)(dian)(dian)(dian)(dian)荷水(shui)平降低，電(dian)(dian)(dian)(dian)(dian)力產(chan)生(sheng)率就會(hui)下降。因(yin)此(ci)，需(xu)要為系統提(ti)供穩(wen)定的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)。儲能技(ji)術主要有多種，如超級(ji)(ji)電(dian)(dian)(dian)(dian)(dian)容器、蓄電(dian)(dian)(dian)(dian)(dian)池等。在電(dian)(dian)(dian)(dian)(dian)量方面，蓄電(dian)(dian)(dian)(dian)(dian)池可(ke)持續提(ti)供幾(ji)個小時的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)量，而超級(ji)(ji)電(dian)(dian)(dian)(dian)(dian)容器只能維持數(shu)分鐘。因(yin)此(ci)，在通(tong)信電(dian)(dian)(dian)(dian)(dian)源(yuan)領域(yu)，使用超級(ji)(ji)電(dian)(dian)(dian)(dian)(dian)容器與(yu)(yu)蓄電(dian)(dian)(dian)(dian)(dian)池相結(jie)合等科學組合可(ke)以(yi)做(zuo)出最優(you)的(de)(de)(de)選擇。

二、通信電源系統供電方式有哪些

為了保證供(gong)(gong)電(dian)的穩定、可(ke)(ke)靠和(he)(he)安全的，根據(ju)不同(tong)的應(ying)用要求，通信電(dian)源(yuan)可(ke)(ke)以采(cai)用不同(tong)的供(gong)(gong)電(dian)方(fang)式(shi)。集中(zhong)供(gong)(gong)電(dian)、分散(san)供(gong)(gong)電(dian)和(he)(he)混合供(gong)(gong)電(dian)是采(cai)用的典(dian)型的三種供(gong)(gong)電(dian)方(fang)式(shi)。

1、集(ji)中供(gong)(gong)電(dian)(dian)是指通信(xin)局（站）中所有通信(xin)設備由一個集(ji)中的直流電(dian)(dian)源(yuan)供(gong)(gong)電(dian)(dian)。

2、分散供電(dian)方式(shi)電(dian)源系(xi)統(tong)(tong)設置多個(ge)直流供電(dian)系(xi)統(tong)(tong)，分別給(gei)局（站(zhan)）內一部分通信設備供電(dian)。

3、混合供(gong)電(dian)(dian)方(fang)(fang)式電(dian)(dian)源(yuan)系統(tong)，在光纜(lan)中繼站、微波(bo)無(wu)人值守中繼站和移動通信基(ji)站等地方(fang)(fang)，可以(yi)采用交流電(dian)(dian)源(yuan)和太(tai)陽電(dian)(dian)池(chi)(chi)（或其他能源(yuan)）相結合的(de)混合供(gong)電(dian)(dian)方(fang)(fang)式電(dian)(dian)源(yuan)系統(tong)進行供(gong)電(dian)(dian)。該系統(tong)由(you)太(tai)陽電(dian)(dian)池(chi)(chi)方(fang)(fang)陣、低壓市電(dian)(dian)、蓄電(dian)(dian)池(chi)(chi)組、整流和配電(dian)(dian)設備以(yi)及移動發電(dian)(dian)機組成。
