【ups電池(chi)】常(chang)用UPS電池(chi)分類與介紹 不同種類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(fen)為(wei)8-10年(nian)，15-20年(nian)壽(shou)命(ming)兩種(zhong)。由于此電(dian)池硫酸電(dian)解會(hui)產(chan)生腐(fu)蝕(shi)性氣(qi)體，此類(lei)電(dian)池必須安裝在(zai)通風并遠離精(jing)密電(dian)子設備的房(fang)間，且(qie)電(dian)池房(fang)應鋪設防腐(fu)蝕(shi)瓷磚。

由于蒸發的原因，開放電池需定期測量比重，加(jia)酸加(jia)水。此電池可忍受高溫高壓和深(shen)放電。電池房應(ying)禁煙并用開放型電池架。

此電(dian)(dian)池(chi)充電(dian)(dian)后(hou)不(bu)能運(yun)輸，因而必須(xu)在現(xian)場安裝后(hou)充電(dian)(dian)初(chu)充電(dian)(dian)一般需55-90小時。正(zheng)常每節電(dian)(dian)壓(ya)為2V，初(chu)充電(dian)(dian)電(dian)(dian)壓(ya)為2.6-2.7v。

2、鎳鉻電池

此類電(dian)(dian)(dian)(dian)池不同于(yu)鉛酸電(dian)(dian)(dian)(dian)池，電(dian)(dian)(dian)(dian)解時產(chan)生氫和氧而(er)不產(chan)生腐蝕性氣體，因而(er)可安裝在電(dian)(dian)(dian)(dian)子設備的旁邊。且水的消耗很少，一般(ban)不需(xu)維護。正(zheng)常壽命為(wei)20-25年(nian)。遠(yuan)比前(qian)面提到的電(dian)(dian)(dian)(dian)池昂貴(gui)。初(chu)始(shi)安裝的費用約為(wei)鉛酸電(dian)(dian)(dian)(dian)池的三(san)倍。并(bing)不會因環境(jing)溫(wen)度高(gao)(gao)而(er)影響(xiang)電(dian)(dian)(dian)(dian)池壽命，也不會因環境(jing)溫(wen)度低而(er)影響(xiang)電(dian)(dian)(dian)(dian)池容量。一般(ban)每節電(dian)(dian)(dian)(dian)壓為(wei)1.2V，UPS因應(ying)用此類電(dian)(dian)(dian)(dian)池需(xu)設計較高(gao)(gao)的充電(dian)(dian)(dian)(dian)器(qi)電(dian)(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(zi)身(shen)結構上的(de)優勢，電(dian)(dian)(dian)解(jie)(jie)液的(de)消耗量非常小，在使(shi)用壽命內(nei)基本不需(xu)要(yao)補(bu)充(chong)蒸餾水。它還具(ju)有耐(nai)震、耐(nai)高溫、體積小、自(zi)放電(dian)(dian)(dian)小的(de)特點(dian)。使(shi)用壽命一(yi)般(ban)為(wei)普通蓄(xu)電(dian)(dian)(dian)池的(de)兩倍。市場上的(de)免(mian)維(wei)護(hu)蓄(xu)電(dian)(dian)(dian)池也有兩種(zhong)(zhong)：第一(yi)種(zhong)(zhong)在購買時一(yi)次(ci)性加電(dian)(dian)(dian)解(jie)(jie)液以(yi)后使(shi)用中(zhong)不需(xu)要(yao)維(wei)護(hu)(添加補(bu)充(chong)液)；另一(yi)種(zhong)(zhong)是電(dian)(dian)(dian)池本身(shen)出廠時就已經加好電(dian)(dian)(dian)解(jie)(jie)液并(bing)封死，用戶根本就不能加補(bu)充(chong)液。

由于(yu)免(mian)維護蓄電(dian)(dian)池采用鉛鈣(gai)合(he)金柵架，充(chong)電(dian)(dian)時產(chan)生(sheng)的(de)水分解量(liang)少(shao)，水份(fen)蒸發(fa)量(liang)低，加(jia)上外殼采用密封結構(gou)，釋放出來(lai)的(de)硫酸氣體也(ye)很少(shao)，所(suo)以它與(yu)傳統蓄電(dian)(dian)池相比，具有不需添加(jia)任何液體，對接線樁頭、電(dian)(dian)線腐蝕少(shao)，抗(kang)過充(chong)電(dian)(dian)能(neng)力強，起動電(dian)(dian)流大，電(dian)(dian)量(liang)儲存時間長等優點。

免(mian)維護蓄電(dian)池(chi)(chi)因(yin)其(qi)在正常(chang)充電(dian)電(dian)壓下，電(dian)解(jie)液僅產(chan)生少(shao)量的氣體，極板(ban)有很強的抗過充電(dian)能力(li)，而且具有內阻小、低溫起動性能好、比(bi)常(chang)規蓄電(dian)池(chi)(chi)使(shi)用壽(shou)命長等(deng)特(te)點，因(yin)而在整個使(shi)用期間(jian)不需(xu)(xu)添(tian)加蒸(zheng)餾水，在充電(dian)系(xi)正常(chang)情況下，不需(xu)(xu)從拆下進行補(bu)充充電(dian)。但在保(bao)養時應對其(qi)電(dian)解(jie)液的比(bi)重進行檢查。

大多數(shu)免維護蓄(xu)(xu)電(dian)(dian)池(chi)在(zai)蓋(gai)上設有一個孔形液體(ti)(溫度補償(chang)型)比(bi)重計，它(ta)會(hui)根(gen)據電(dian)(dian)解液比(bi)重的(de)變化而改變顏色(se)(se)。可以(yi)指(zhi)(zhi)示(shi)蓄(xu)(xu)電(dian)(dian)池(chi)的(de)存放電(dian)(dian)狀(zhuang)態(tai)和電(dian)(dian)解液液位的(de)高度。當(dang)比(bi)重計的(de)指(zhi)(zhi)示(shi)眼呈綠色(se)(se)時，表(biao)明充(chong)電(dian)(dian)已足，蓄(xu)(xu)電(dian)(dian)池(chi)正常；當(dang)指(zhi)(zhi)示(shi)眼綠點很(hen)少或為黑色(se)(se)，表(biao)明蓄(xu)(xu)電(dian)(dian)池(chi)需要(yao)充(chong)電(dian)(dian)；當(dang)指(zhi)(zhi)示(shi)眼顯示(shi)淡(dan)黃色(se)(se)，表(biao)明蓄(xu)(xu)電(dian)(dian)池(chi)內部有故障，需要(yao)修理或進行更換(huan)。
