【ups電池(chi)】常用UPS電池(chi)分(fen)類與介紹 不同種類UPS電池(chi)的特(te)點(dian)說(shuo)明

1、開放型液體鉛酸電池

此(ci)類電(dian)(dian)池按(an)結構可(ke)分為8-10年(nian)，15-20年(nian)壽命兩(liang)種(zhong)。由于(yu)此(ci)電(dian)(dian)池硫(liu)酸電(dian)(dian)解(jie)會產生腐蝕(shi)性(xing)氣體，此(ci)類電(dian)(dian)池必須(xu)安裝在通風并遠(yuan)離精密電(dian)(dian)子設備的房(fang)間，且電(dian)(dian)池房(fang)應鋪(pu)設防腐蝕(shi)瓷磚。

由于蒸發的(de)原因，開(kai)放(fang)電(dian)(dian)池(chi)需定(ding)期測量比重，加(jia)酸加(jia)水。此電(dian)(dian)池(chi)可忍受(shou)高(gao)溫(wen)高(gao)壓和深放(fang)電(dian)(dian)。電(dian)(dian)池(chi)房應禁煙并用(yong)開(kai)放(fang)型(xing)電(dian)(dian)池(chi)架(jia)。

此(ci)電(dian)池充(chong)(chong)電(dian)后(hou)不能運輸，因(yin)而必須在現場(chang)安裝后(hou)充(chong)(chong)電(dian)初充(chong)(chong)電(dian)一般(ban)需55-90小時。正常每節電(dian)壓為2V，初充(chong)(chong)電(dian)電(dian)壓為2.6-2.7v。

2、鎳鉻電池

此(ci)類電(dian)(dian)(dian)池不(bu)(bu)同于鉛酸電(dian)(dian)(dian)池，電(dian)(dian)(dian)解時(shi)產生氫和氧而(er)不(bu)(bu)產生腐蝕性氣體，因而(er)可安(an)裝在電(dian)(dian)(dian)子設備的旁邊。且(qie)水的消耗很少，一般不(bu)(bu)需維護。正常壽命(ming)為20-25年。遠(yuan)比前面提到的電(dian)(dian)(dian)池昂貴。初始安(an)裝的費(fei)用約為鉛酸電(dian)(dian)(dian)池的三倍(bei)。并不(bu)(bu)會因環境溫度(du)高(gao)(gao)而(er)影響電(dian)(dian)(dian)池壽命(ming)，也(ye)不(bu)(bu)會因環境溫度(du)低(di)而(er)影響電(dian)(dian)(dian)池容量(liang)。一般每節(jie)電(dian)(dian)(dian)壓為1.2V，UPS因應用此(ci)類電(dian)(dian)(dian)池需設計較高(gao)(gao)的充電(dian)(dian)(dian)器電(dian)(dian)(dian)壓。

3、免維護蓄電池

又名閥控式密封鉛酸蓄電池，免維護蓄電池由于自身結構(gou)上的(de)(de)優勢，電(dian)(dian)(dian)解液的(de)(de)消耗量非常小，在(zai)使用(yong)(yong)壽命內基本(ben)不(bu)需要補充蒸餾水。它(ta)還具有耐震、耐高溫、體積小、自放(fang)電(dian)(dian)(dian)小的(de)(de)特點。使用(yong)(yong)壽命一般為普通蓄電(dian)(dian)(dian)池的(de)(de)兩倍。市場上的(de)(de)免維(wei)護(hu)蓄電(dian)(dian)(dian)池也(ye)有兩種(zhong)：第(di)一種(zhong)在(zai)購(gou)買時一次性加(jia)(jia)電(dian)(dian)(dian)解液以后(hou)使用(yong)(yong)中不(bu)需要維(wei)護(hu)(添(tian)加(jia)(jia)補充液)；另(ling)一種(zhong)是電(dian)(dian)(dian)池本(ben)身出廠時就已經加(jia)(jia)好(hao)電(dian)(dian)(dian)解液并封(feng)死(si)，用(yong)(yong)戶根本(ben)就不(bu)能加(jia)(jia)補充液。

由于免維護蓄電(dian)池采用(yong)鉛鈣合金(jin)柵架，充電(dian)時(shi)產生的(de)水(shui)分解量少，水(shui)份蒸發量低，加上外殼采用(yong)密封結構，釋放出來的(de)硫酸(suan)氣體(ti)(ti)也(ye)很(hen)少，所以它(ta)與(yu)傳(chuan)統蓄電(dian)池相比，具(ju)有(you)不需添加任何液(ye)體(ti)(ti)，對接線樁頭、電(dian)線腐蝕少，抗過充電(dian)能力強，起動電(dian)流(liu)大(da)，電(dian)量儲存時(shi)間長(chang)等優點。

免(mian)維護(hu)蓄電池因其在(zai)正(zheng)常(chang)充(chong)(chong)電電壓下，電解(jie)液僅(jin)產生少(shao)量的氣體，極(ji)板有很強的抗(kang)過充(chong)(chong)電能力，而且(qie)具(ju)有內阻(zu)小、低溫起動(dong)性能好、比(bi)常(chang)規蓄電池使用(yong)壽命長等特(te)點，因而在(zai)整(zheng)個使用(yong)期間不(bu)需添加蒸(zheng)餾水，在(zai)充(chong)(chong)電系正(zheng)常(chang)情況下，不(bu)需從拆下進(jin)行(xing)補(bu)充(chong)(chong)充(chong)(chong)電。但(dan)在(zai)保(bao)養時應對(dui)其電解(jie)液的比(bi)重進(jin)行(xing)檢查。

大多數免維護蓄(xu)電(dian)(dian)(dian)池在蓋上設有(you)一(yi)個孔形液體(溫度補償型)比(bi)重計，它會根據(ju)電(dian)(dian)(dian)解液比(bi)重的(de)變化而改變顏(yan)色。可以指(zhi)(zhi)示(shi)(shi)蓄(xu)電(dian)(dian)(dian)池的(de)存放電(dian)(dian)(dian)狀態和(he)電(dian)(dian)(dian)解液液位的(de)高度。當(dang)(dang)比(bi)重計的(de)指(zhi)(zhi)示(shi)(shi)眼(yan)呈綠色時，表(biao)明(ming)充電(dian)(dian)(dian)已足(zu)，蓄(xu)電(dian)(dian)(dian)池正常；當(dang)(dang)指(zhi)(zhi)示(shi)(shi)眼(yan)綠點很少(shao)或(huo)為黑(hei)色，表(biao)明(ming)蓄(xu)電(dian)(dian)(dian)池需要充電(dian)(dian)(dian)；當(dang)(dang)指(zhi)(zhi)示(shi)(shi)眼(yan)顯示(shi)(shi)淡黃色，表(biao)明(ming)蓄(xu)電(dian)(dian)(dian)池內(nei)部有(you)故障(zhang)，需要修(xiu)理或(huo)進行更換。
