【ups電池】常用UPS電池分類與介紹 不同種類UPS電池的特點說明

1、開放型液體鉛酸電池

此(ci)類電(dian)池按結(jie)構可(ke)分為8-10年，15-20年壽命兩種。由于(yu)此(ci)電(dian)池硫酸電(dian)解會產生腐蝕性(xing)氣體(ti)，此(ci)類電(dian)池必須安裝在通風并遠離(li)精密電(dian)子(zi)設備的房間，且電(dian)池房應鋪(pu)設防腐蝕瓷磚。

由于蒸發的原因，開(kai)放(fang)電(dian)池需定期測(ce)量比重，加酸加水(shui)。此電(dian)池可忍受高溫高壓和深放(fang)電(dian)。電(dian)池房應禁煙并用開(kai)放(fang)型電(dian)池架。

此(ci)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)后不能運(yun)輸，因而(er)必須在(zai)現場安裝后充(chong)電(dian)(dian)(dian)初充(chong)電(dian)(dian)(dian)一般需55-90小時。正常(chang)每節電(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(lei)電(dian)(dian)(dian)(dian)池(chi)不(bu)同(tong)于鉛酸電(dian)(dian)(dian)(dian)池(chi)，電(dian)(dian)(dian)(dian)解時產生氫和氧而(er)不(bu)產生腐蝕性氣體，因而(er)可安裝在電(dian)(dian)(dian)(dian)子設備的(de)(de)(de)旁邊(bian)。且(qie)水的(de)(de)(de)消(xiao)耗很少，一(yi)般不(bu)需維護(hu)。正(zheng)常壽(shou)命為20-25年。遠比前(qian)面提到(dao)的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)昂貴。初始安裝的(de)(de)(de)費(fei)用約為鉛酸電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)三倍。并不(bu)會(hui)因環境(jing)溫(wen)度(du)高(gao)而(er)影響(xiang)(xiang)電(dian)(dian)(dian)(dian)池(chi)壽(shou)命，也不(bu)會(hui)因環境(jing)溫(wen)度(du)低而(er)影響(xiang)(xiang)電(dian)(dian)(dian)(dian)池(chi)容量。一(yi)般每節電(dian)(dian)(dian)(dian)壓(ya)(ya)為1.2V，UPS因應用此類(lei)電(dian)(dian)(dian)(dian)池(chi)需設計(ji)較高(gao)的(de)(de)(de)充電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)壓(ya)(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)(de)優(you)勢(shi)，電(dian)(dian)(dian)(dian)解(jie)液(ye)的(de)(de)消耗(hao)量非常小(xiao)，在(zai)使用(yong)壽命(ming)內基本(ben)(ben)不(bu)需(xu)(xu)要(yao)補(bu)(bu)充(chong)(chong)蒸餾水(shui)。它還具有(you)耐(nai)(nai)震、耐(nai)(nai)高溫、體(ti)積小(xiao)、自放電(dian)(dian)(dian)(dian)小(xiao)的(de)(de)特點。使用(yong)壽命(ming)一(yi)般為(wei)普通(tong)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)兩倍。市場上的(de)(de)免(mian)維護蓄(xu)電(dian)(dian)(dian)(dian)池(chi)也有(you)兩種：第一(yi)種在(zai)購買(mai)時(shi)一(yi)次性加(jia)(jia)電(dian)(dian)(dian)(dian)解(jie)液(ye)以后(hou)使用(yong)中不(bu)需(xu)(xu)要(yao)維護(添加(jia)(jia)補(bu)(bu)充(chong)(chong)液(ye))；另一(yi)種是電(dian)(dian)(dian)(dian)池(chi)本(ben)(ben)身出廠時(shi)就(jiu)已經加(jia)(jia)好(hao)電(dian)(dian)(dian)(dian)解(jie)液(ye)并封死，用(yong)戶(hu)根本(ben)(ben)就(jiu)不(bu)能加(jia)(jia)補(bu)(bu)充(chong)(chong)液(ye)。

由于免(mian)維護蓄電(dian)(dian)池(chi)采用鉛鈣(gai)合金柵(zha)架，充(chong)電(dian)(dian)時(shi)產(chan)生(sheng)的水(shui)分解量(liang)少，水(shui)份蒸發量(liang)低，加上外殼采用密封結(jie)構，釋放出來的硫酸(suan)氣體也(ye)很少，所以它(ta)與傳統(tong)蓄電(dian)(dian)池(chi)相比，具有不需添加任(ren)何(he)液體，對接線樁頭、電(dian)(dian)線腐蝕少，抗過充(chong)電(dian)(dian)能力強，起動電(dian)(dian)流大，電(dian)(dian)量(liang)儲存時(shi)間長等優點。

免維護蓄電(dian)池因(yin)其(qi)在(zai)正常充(chong)(chong)電(dian)電(dian)壓下(xia)，電(dian)解(jie)液(ye)僅產生少(shao)量(liang)的(de)氣(qi)體，極板有很強(qiang)的(de)抗過充(chong)(chong)電(dian)能力，而(er)且(qie)具有內(nei)阻小(xiao)、低溫起(qi)動性能好(hao)、比(bi)常規蓄電(dian)池使用(yong)壽命長等特點，因(yin)而(er)在(zai)整個使用(yong)期間不(bu)需添(tian)加蒸餾(liu)水，在(zai)充(chong)(chong)電(dian)系正常情(qing)況下(xia)，不(bu)需從(cong)拆下(xia)進行(xing)補充(chong)(chong)充(chong)(chong)電(dian)。但在(zai)保養時應(ying)對其(qi)電(dian)解(jie)液(ye)的(de)比(bi)重進行(xing)檢查。

大多數免(mian)維護蓄(xu)(xu)電(dian)(dian)(dian)(dian)池在蓋上設有(you)一(yi)個孔(kong)形液體(溫度補(bu)償型(xing))比(bi)重(zhong)(zhong)計，它會根據電(dian)(dian)(dian)(dian)解(jie)液比(bi)重(zhong)(zhong)的變化(hua)而改變顏色(se)。可(ke)以(yi)指(zhi)(zhi)示蓄(xu)(xu)電(dian)(dian)(dian)(dian)池的存放電(dian)(dian)(dian)(dian)狀態和電(dian)(dian)(dian)(dian)解(jie)液液位的高度。當比(bi)重(zhong)(zhong)計的指(zhi)(zhi)示眼呈綠(lv)色(se)時(shi)，表(biao)明(ming)充電(dian)(dian)(dian)(dian)已足，蓄(xu)(xu)電(dian)(dian)(dian)(dian)池正常；當指(zhi)(zhi)示眼綠(lv)點很少或為黑色(se)，表(biao)明(ming)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池需要充電(dian)(dian)(dian)(dian)；當指(zhi)(zhi)示眼顯示淡黃色(se)，表(biao)明(ming)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池內部(bu)有(you)故(gu)障，需要修理或進行更(geng)換。
