【ups電(dian)池(chi)】常(chang)用UPS電(dian)池(chi)分(fen)類與介(jie)紹 不同(tong)種類UPS電(dian)池(chi)的(de)特點說明

1、開放型液體鉛酸電池

此類(lei)(lei)電(dian)(dian)池(chi)按(an)結(jie)構可分為8-10年，15-20年壽(shou)命兩(liang)種(zhong)。由于此電(dian)(dian)池(chi)硫酸電(dian)(dian)解會產生腐蝕性氣體，此類(lei)(lei)電(dian)(dian)池(chi)必須安裝在(zai)通風并遠離精密(mi)電(dian)(dian)子設(she)(she)備的房間，且電(dian)(dian)池(chi)房應鋪(pu)設(she)(she)防(fang)腐蝕瓷磚(zhuan)。

由于蒸發的原(yuan)因(yin)，開放電(dian)池(chi)需定期測量(liang)比重，加酸加水(shui)。此電(dian)池(chi)可忍(ren)受高(gao)溫高(gao)壓和深(shen)放電(dian)。電(dian)池(chi)房應禁煙并用(yong)開放型(xing)電(dian)池(chi)架。

此電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)后不能運輸，因(yin)而必須在現(xian)場安裝后充(chong)電(dian)(dian)(dian)初充(chong)電(dian)(dian)(dian)一般需55-90小時(shi)。正常每節(jie)電(dian)(dian)(dian)壓為2V，初充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓為2.6-2.7v。

2、鎳鉻電池

此類電(dian)(dian)池(chi)不(bu)同于鉛(qian)酸電(dian)(dian)池(chi)，電(dian)(dian)解時產(chan)生(sheng)氫和氧而不(bu)產(chan)生(sheng)腐蝕性(xing)氣體，因而可安(an)(an)裝(zhuang)在電(dian)(dian)子設(she)備的(de)旁(pang)邊。且(qie)水的(de)消耗很少(shao)，一般不(bu)需維護。正(zheng)常壽命(ming)為20-25年。遠比前面提到的(de)電(dian)(dian)池(chi)昂貴。初始安(an)(an)裝(zhuang)的(de)費用約為鉛(qian)酸電(dian)(dian)池(chi)的(de)三倍。并不(bu)會因環(huan)境溫度高(gao)(gao)而影響(xiang)電(dian)(dian)池(chi)壽命(ming)，也不(bu)會因環(huan)境溫度低而影響(xiang)電(dian)(dian)池(chi)容(rong)量。一般每節電(dian)(dian)壓為1.2V，UPS因應用此類電(dian)(dian)池(chi)需設(she)計較高(gao)(gao)的(de)充(chong)電(dian)(dian)器(qi)電(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上(shang)的(de)(de)優勢，電(dian)(dian)(dian)(dian)解液(ye)的(de)(de)消耗量非(fei)常(chang)小(xiao)(xiao)，在使用(yong)壽(shou)命內(nei)基本不需(xu)要(yao)補(bu)充蒸(zheng)餾水。它(ta)還具有(you)(you)耐(nai)震、耐(nai)高溫(wen)、體積小(xiao)(xiao)、自放電(dian)(dian)(dian)(dian)小(xiao)(xiao)的(de)(de)特(te)點。使用(yong)壽(shou)命一般為(wei)普通蓄電(dian)(dian)(dian)(dian)池(chi)的(de)(de)兩(liang)倍。市場上(shang)的(de)(de)免維(wei)護蓄電(dian)(dian)(dian)(dian)池(chi)也有(you)(you)兩(liang)種：第一種在購(gou)買(mai)時(shi)一次性加電(dian)(dian)(dian)(dian)解液(ye)以后使用(yong)中(zhong)不需(xu)要(yao)維(wei)護(添加補(bu)充液(ye))；另一種是(shi)電(dian)(dian)(dian)(dian)池(chi)本身出廠時(shi)就(jiu)已經加好電(dian)(dian)(dian)(dian)解液(ye)并(bing)封死，用(yong)戶(hu)根本就(jiu)不能加補(bu)充液(ye)。

由于免維護蓄(xu)電池采用鉛鈣合金柵架，充電時產生的水分解量(liang)(liang)少，水份蒸(zheng)發量(liang)(liang)低，加上(shang)外殼采用密封結構，釋放出來的硫(liu)酸(suan)氣體也很少，所以它與傳統蓄(xu)電池相比，具(ju)有不需添加任何液體，對接(jie)線(xian)樁頭、電線(xian)腐蝕少，抗過(guo)充電能力強，起動電流大，電量(liang)(liang)儲存時間長等優點(dian)。

免維護(hu)蓄電(dian)(dian)池因(yin)其在正常充(chong)電(dian)(dian)電(dian)(dian)壓下(xia)，電(dian)(dian)解(jie)(jie)液(ye)(ye)僅產生少量的氣體(ti)，極板有很強(qiang)的抗過充(chong)電(dian)(dian)能力，而且具有內阻小、低溫起動性能好、比常規蓄電(dian)(dian)池使用壽命長(chang)等特點，因(yin)而在整個使用期(qi)間不(bu)需添加蒸餾水，在充(chong)電(dian)(dian)系正常情況下(xia)，不(bu)需從拆(chai)下(xia)進行補充(chong)充(chong)電(dian)(dian)。但(dan)在保養(yang)時應對其電(dian)(dian)解(jie)(jie)液(ye)(ye)的比重進行檢查(cha)。

大多數免維(wei)護蓄電(dian)(dian)(dian)池(chi)在蓋上設有(you)(you)一個(ge)孔形液(ye)體(ti)(溫度(du)補償(chang)型)比(bi)(bi)重計(ji)，它會根(gen)據(ju)電(dian)(dian)(dian)解液(ye)比(bi)(bi)重的變化而(er)改變顏色(se)(se)。可以指示(shi)蓄電(dian)(dian)(dian)池(chi)的存放(fang)電(dian)(dian)(dian)狀態和電(dian)(dian)(dian)解液(ye)液(ye)位的高度(du)。當(dang)(dang)比(bi)(bi)重計(ji)的指示(shi)眼呈綠色(se)(se)時(shi)，表明充電(dian)(dian)(dian)已足，蓄電(dian)(dian)(dian)池(chi)正常；當(dang)(dang)指示(shi)眼綠點很少或為黑色(se)(se)，表明蓄電(dian)(dian)(dian)池(chi)需(xu)要充電(dian)(dian)(dian)；當(dang)(dang)指示(shi)眼顯示(shi)淡黃色(se)(se)，表明蓄電(dian)(dian)(dian)池(chi)內部有(you)(you)故(gu)障，需(xu)要修理或進行更(geng)換。
