【ups電池(chi)】常用(yong)UPS電池(chi)分類與介紹 不同種(zhong)類UPS電池(chi)的特點說明

1、開放型液體鉛酸電池

此類(lei)電(dian)池按結構可分為(wei)8-10年(nian)(nian)，15-20年(nian)(nian)壽命兩種。由于此電(dian)池硫酸(suan)電(dian)解會(hui)產生腐蝕性氣體，此類(lei)電(dian)池必須安裝在通風并遠離精密電(dian)子(zi)設備的房間(jian)，且電(dian)池房應鋪設防(fang)腐蝕瓷磚。

由于蒸發的(de)原因(yin)，開(kai)放電池需定期測量比(bi)重，加酸(suan)加水(shui)。此電池可忍受(shou)高溫高壓和深放電。電池房應禁煙并用開(kai)放型電池架(jia)。

此電池(chi)充(chong)電后(hou)不能(neng)運(yun)輸，因(yin)而(er)必須在(zai)現場(chang)安裝后(hou)充(chong)電初(chu)充(chong)電一般需55-90小時。正常(chang)每節電壓(ya)為2V，初(chu)充(chong)電電壓(ya)為2.6-2.7v。

2、鎳鉻電池

此類電(dian)(dian)(dian)(dian)池不同于鉛酸(suan)(suan)電(dian)(dian)(dian)(dian)池，電(dian)(dian)(dian)(dian)解時(shi)產生(sheng)氫(qing)和氧(yang)而(er)不產生(sheng)腐蝕性氣(qi)體(ti)，因(yin)(yin)而(er)可安(an)裝在電(dian)(dian)(dian)(dian)子設(she)備的(de)旁邊。且水(shui)的(de)消耗很少，一(yi)般(ban)不需維護。正(zheng)常壽命(ming)為(wei)20-25年。遠比前面(mian)提到的(de)電(dian)(dian)(dian)(dian)池昂貴。初始安(an)裝的(de)費(fei)用約為(wei)鉛酸(suan)(suan)電(dian)(dian)(dian)(dian)池的(de)三倍(bei)。并不會因(yin)(yin)環境溫(wen)度高而(er)影(ying)響電(dian)(dian)(dian)(dian)池壽命(ming)，也不會因(yin)(yin)環境溫(wen)度低而(er)影(ying)響電(dian)(dian)(dian)(dian)池容量。一(yi)般(ban)每(mei)節電(dian)(dian)(dian)(dian)壓(ya)為(wei)1.2V，UPS因(yin)(yin)應用此類電(dian)(dian)(dian)(dian)池需設(she)計較高的(de)充電(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)壓(ya)。

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上的(de)優勢，電解(jie)液(ye)(ye)的(de)消(xiao)耗量非常小(xiao)，在(zai)使用(yong)壽命內基本(ben)不(bu)需(xu)(xu)要補(bu)充蒸(zheng)餾(liu)水。它還具(ju)有耐震、耐高(gao)溫、體積小(xiao)、自放電小(xiao)的(de)特(te)點。使用(yong)壽命一般為(wei)普通蓄電池(chi)的(de)兩(liang)(liang)倍。市場上的(de)免(mian)維護蓄電池(chi)也有兩(liang)(liang)種(zhong)：第一種(zhong)在(zai)購買時一次性加電解(jie)液(ye)(ye)以后使用(yong)中不(bu)需(xu)(xu)要維護(添加補(bu)充液(ye)(ye))；另一種(zhong)是電池(chi)本(ben)身出廠時就(jiu)已(yi)經加好電解(jie)液(ye)(ye)并封死，用(yong)戶根本(ben)就(jiu)不(bu)能加補(bu)充液(ye)(ye)。

由(you)于免維護蓄電(dian)(dian)池采用(yong)(yong)鉛鈣(gai)合(he)金(jin)柵架，充(chong)電(dian)(dian)時產生的水分(fen)解(jie)量少(shao)(shao)，水份(fen)蒸發量低，加上(shang)外殼采用(yong)(yong)密封結構，釋放(fang)出來的硫酸氣體(ti)也很少(shao)(shao)，所以(yi)它與傳統蓄電(dian)(dian)池相比(bi)，具有不(bu)需添加任何液體(ti)，對接線(xian)樁頭、電(dian)(dian)線(xian)腐蝕少(shao)(shao)，抗過充(chong)電(dian)(dian)能力強(qiang)，起動(dong)電(dian)(dian)流(liu)大，電(dian)(dian)量儲(chu)存(cun)時間長等優(you)點。

免維護蓄電(dian)(dian)(dian)池(chi)因(yin)其在正(zheng)常(chang)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓下，電(dian)(dian)(dian)解(jie)(jie)液僅產(chan)生少量(liang)的氣(qi)體，極板有(you)很(hen)強的抗(kang)過充(chong)電(dian)(dian)(dian)能(neng)(neng)力(li)，而且具有(you)內阻小(xiao)、低溫起動性能(neng)(neng)好、比常(chang)規蓄電(dian)(dian)(dian)池(chi)使(shi)(shi)用(yong)(yong)壽命長等(deng)特(te)點，因(yin)而在整(zheng)個(ge)使(shi)(shi)用(yong)(yong)期間不(bu)需添加蒸餾水(shui)，在充(chong)電(dian)(dian)(dian)系正(zheng)常(chang)情況(kuang)下，不(bu)需從拆(chai)下進行補充(chong)充(chong)電(dian)(dian)(dian)。但(dan)在保養(yang)時(shi)應(ying)對其電(dian)(dian)(dian)解(jie)(jie)液的比重(zhong)進行檢(jian)查。

大多數免維護蓄(xu)電(dian)(dian)池在(zai)蓋(gai)上設有一個孔(kong)形液體(溫度補償型)比重(zhong)(zhong)計(ji)，它會根據電(dian)(dian)解液比重(zhong)(zhong)的變(bian)化而改(gai)變(bian)顏色。可(ke)以指示(shi)(shi)蓄(xu)電(dian)(dian)池的存(cun)放(fang)電(dian)(dian)狀態和電(dian)(dian)解液液位的高度。當比重(zhong)(zhong)計(ji)的指示(shi)(shi)眼(yan)(yan)呈綠色時，表明充電(dian)(dian)已足，蓄(xu)電(dian)(dian)池正常(chang)；當指示(shi)(shi)眼(yan)(yan)綠點很少或(huo)為黑色，表明蓄(xu)電(dian)(dian)池需要(yao)充電(dian)(dian)；當指示(shi)(shi)眼(yan)(yan)顯示(shi)(shi)淡(dan)黃色，表明蓄(xu)電(dian)(dian)池內部有故(gu)障，需要(yao)修(xiu)理或(huo)進行更換。
