【蓄電池(chi)容(rong)量(liang)】蓄電池(chi)容(rong)量(liang)計算公式 蓄電池(chi)容(rong)量(liang)測試新(xin)技(ji)術介紹

蓄電池容量計算公式

容量=放(fang)電電流(liu)×放(fang)電時間

蓄電(dian)(dian)池的(de)容(rong)(rong)量與放電(dian)(dian)電(dian)(dian)流(liu)大(da)小及(ji)電(dian)(dian)解液(ye)的(de)溫(wen)度(du)有(you)關，因此(ci)標稱容(rong)(rong)量是在(zai)一定(ding)的(de)放電(dian)(dian)電(dian)(dian)流(liu)、一定(ding)的(de)終(zhong)止電(dian)(dian)壓和一定(ding)的(de)電(dian)(dian)解液(ye)溫(wen)度(du)下取得(de)的(de)，標容(rong)(rong)量有(you)兩種。

額定容量

額定容量是指完全充足電的蓄電池在電解液平均溫度30 ℃的(de)情況下，以20小時率(lv)放電(dian)的電(dian)流（相當于額定容(rong)量的1/20）連續放電至(zhi)單體1.75V時輸出(chu)的電量。

起動容量

常溫起動容量：指電解液溫度為30 ℃時，以5min率放(fang)電電流（3倍額定(ding)容量電(dian)流(liu)）連續(xu)放(fang)電(dian)至規定(ding)的終止電(dian)壓（6V蓄電池為(wei)4.5V，12V蓄電池為9V）時，所輸出的(de)電(dian)量，其(qi)放電(dian)持續(xu)時間應在5min以上

低溫起動容量：電解液溫度為-18℃時(shi)，以3倍額(e)定(ding)容量的電流(liu)連續放(fang)電至(zhi)規定(ding)終止(zhi)電壓（12V蓄電池(chi)為(wei)6V，6V蓄電(dian)池為3V）時所放(fang)出的(de)電量，其放(fang)電持續時間應(ying)在2.5min以上(shang)。

蓄電池容量測試新技術介紹

通(tong)訊后(hou)備蓄電(dian)池(chi)質量是通(tong)訊網(wang)絡(luo)供電(dian)不中斷的(de)重要保障，是整個(ge)通(tong)訊電(dian)源(yuan)設備供電(dian)保障，保證通(tong)訊網(wang)絡(luo)正常(chang)運行的(de)最后(hou)一道防線。根據蓄電(dian)池(chi)特性和維護(hu)要求(qiu)，蓄電(dian)池(chi)放電(dian)容量測試工作是必不可少(shao)的(de)。

隨著通訊(xun)網絡規(gui)模的迅猛發展，現網電(dian)(dian)(dian)源(yuan)維(wei)護專業技術(shu)職員(yuan)相對(dui)較少，當前電(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)容量測(ce)(ce)試(shi)方式存(cun)在安全(quan)隱患(huan)，操(cao)縱(zong)復雜，測(ce)(ce)試(shi)工作(zuo)量大的題目，致使維(wei)護規(gui)程要(yao)求(qiu)的電(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)測(ce)(ce)試(shi)工作(zuo)得(de)不到有(you)效落實，落后電(dian)(dian)(dian)池(chi)不能及時得(de)到預警和維(wei)護，在用電(dian)(dian)(dian)池(chi)往往被提前報(bao)廢，造成資源(yuan)浪費。

團(tuan)體公(gong)司、福建(jian)公(gong)司針對電(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)技術聯(lian)合進(jin)行研究，導進(jin)了創新性(xing)的(de)(de)全在(zai)線電(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)技術，全面解決了幾(ji)十年來原(yuan)電(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)技術中存在(zai)的(de)(de)安(an)全隱(yin)患題(ti)目。

1、當前電池放電技術分析

1.1離線式放電法技術分析

（1）將(jiang)其中一(yi)組(zu)電(dian)(dian)(dian)(dian)(dian)池脫離系統(tong)后，一(yi)旦市(shi)電(dian)(dian)(dian)(dian)(dian)中斷，系統(tong)備用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)池供(gong)電(dian)(dian)(dian)(dian)(dian)時間明顯縮短，何(he)況此(ci)(ci)時尚不清楚另一(yi)組(zu)在(zai)線(xian)電(dian)(dian)(dian)(dian)(dian)池是否存(cun)在(zai)質量題(ti)目，此(ci)(ci)放(fang)電(dian)(dian)(dian)(dian)(dian)方式事故風險性高(gao)。如(ru)要用(yong)(yong)此(ci)(ci)方式放(fang)電(dian)(dian)(dian)(dian)(dian)，建議提前啟用(yong)(yong)發(fa)動機(ji)組(zu)，并確保發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)組(zu)、開關電(dian)(dian)(dian)(dian)(dian)源等設備能正常(chang)運行，保證(zheng)安全；

（2）離線放(fang)電(dian)(dian)(dian)(dian)結束后的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)(zu)與在線電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)(zu)間(jian)存(cun)在較大(da)電(dian)(dian)(dian)(dian)壓(ya)(ya)差，若操縱(zong)不當(dang)將(jiang)引(yin)起(qi)開關電(dian)(dian)(dian)(dian)源和在線電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)(zu)對(dui)離線放(fang)電(dian)(dian)(dian)(dian)后的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)(zu)進(jin)行大(da)電(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)，產生(sheng)(sheng)巨大(da)火(huo)花，易發生(sheng)(sheng)安全(quan)事故。用此方式放(fang)電(dian)(dian)(dian)(dian)，需(xu)要配備一(yi)臺整組(zu)(zu)(zu)智能(neng)充(chong)電(dian)(dian)(dian)(dian)機，對(dui)該離線電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)(zu)先充(chong)電(dian)(dian)(dian)(dian)恢(hui)復(fu)后再(zai)并聯回(hui)系(xi)統，以解決打火(huo)花題目(mu)，這(zhe)樣將(jiang)使系(xi)統更長時間(jian)處于單組(zu)(zu)(zu)供(gong)電(dian)(dian)(dian)(dian)狀態，事故風險高(gao)。另通過(guo)調整整流器輸出與被放(fang)電(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)(zu)電(dian)(dian)(dian)(dian)壓(ya)(ya)相(xiang)等后進(jin)行恢(hui)復(fu)連接。上述操縱(zong)一(yi)定(ding)要謹慎(shen)操縱(zong)；

（3）此(ci)放電(dian)(dian)方式操縱(zong)時既要(yao)脫離電(dian)(dian)池(chi)組(zu)的(de)正極(ji)，又(you)要(yao)脫離電(dian)(dian)池(chi)組(zu)的(de)負極(ji)，尤(you)其是(shi)脫離電(dian)(dian)池(chi)組(zu)負極(ji)時需要(yao)特別小(xiao)心(xin)，操縱(zong)不當(dang)引(yin)起負極(ji)短路(lu)，將(jiang)造成(cheng)系統(tong)供電(dian)(dian)中斷，導致(zhi)通訊事故的(de)發生；

（4）此方式(shi)是將電池通過假負(fu)載(zai)以熱量形式(shi)消耗，浪(lang)費(fei)電能，影響(xiang)機房(fang)設備運行(xing)環境，需要維護(hu)職員(yuan)時刻(ke)守護(hu)以免高溫引發事(shi)故。

1.2在線評估式放電法技術分析

（1）調整(zheng)整(zheng)流器(qi)輸(shu)出電(dian)(dian)(dian)壓(ya)至(zhi)保護低(di)(di)壓(ya)值（如46V），使所有(you)后備(bei)電(dian)(dian)(dian)池組直接(jie)對(dui)實際負(fu)荷進行(xing)放(fang)(fang)電(dian)(dian)(dian)至(zhi)整(zheng)流器(qi)輸(shu)出電(dian)(dian)(dian)壓(ya)保護設置值。由于現網系統設備(bei)盡大多數電(dian)(dian)(dian)池配置后備(bei)供電(dian)(dian)(dian)時(shi)間(jian)(jian)為(wei)1～4h，放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流大，應考慮電(dian)(dian)(dian)池組至(zhi)設備(bei)供電(dian)(dian)(dian)回路壓(ya)降及設備(bei)低(di)(di)壓(ya)工作門限(xian)，以(yi)及保證系統供電(dian)(dian)(dian)安(an)全，在線評估式(shi)放(fang)(fang)電(dian)(dian)(dian)其調整(zheng)整(zheng)流器(qi)輸(shu)出電(dian)(dian)(dian)壓(ya)不答應過低(di)(di)（如46V），放(fang)(fang)電(dian)(dian)(dian)深度有(you)限(xian)，對(dui)實際負(fu)載的放(fang)(fang)電(dian)(dian)(dian)時(shi)間(jian)(jian)把握比(bi)較困難，評估電(dian)(dian)(dian)池容量(liang)難以(yi)正(zheng)確(que)，對(dui)電(dian)(dian)(dian)池性(xing)能測試有(you)不確(que)定因素存在，從(cong)而對(dui)保持電(dian)(dian)(dian)池組活性(xing)這一(yi)放(fang)(fang)電(dian)(dian)(dian)測試目的難以(yi)達到維護預期(qi)工作效果；

（2）假如兩組電(dian)池都有失容或欠容、落后等質(zhi)量題目，當(dang)其放電(dian)至整流器(qi)輸出保護值的(de)時(shi)間，不易被維護職(zhi)員及時(shi)發現，此時(shi)可(ke)能后備電(dian)池容量所剩無幾，存在(zai)高風(feng)險。在(zai)此情況下(xia)，此放電(dian)方(fang)式(shi)比(bi)離線放電(dian)方(fang)式(shi)安全性(xing)更低(di)；

（3）由于(yu)放電(dian)(dian)深度有(you)限，對保持電(dian)(dian)池組(zu)(zu)的(de)活性(xing)這一放電(dian)(dian)測試的(de)目的(de)無(wu)(wu)法達(da)到，更(geng)為關鍵(jian)的(de)是在全容量放電(dian)(dian)的(de)實踐中(zhong)我們(men)經常(chang)發現(xian)有(you)些電(dian)(dian)池組(zu)(zu)在放電(dian)(dian)前期(qi)表現(xian)正常(chang)，但(dan)到中(zhong)后期(qi)，有(you)些落后電(dian)(dian)池才(cai)開始逐(zhu)步暴露出來。這一部(bu)分落后單體，于(yu)此放電(dian)(dian)方式(shi)的(de)深度不(bu)夠而(er)沒有(you)被發現(xian)。所以我們(men)稱(cheng)此放電(dian)(dian)方式(shi)為在線評估式(shi)，它(ta)只能大(da)致評估電(dian)(dian)池組(zu)(zu)性(xing)能，或檢(jian)測此電(dian)(dian)池組(zu)(zu)可(ke)以放電(dian)(dian)至此保護電(dian)(dian)壓的(de)時間是非，而(er)無(wu)(wu)法進一步檢(jian)查除此時間外究竟還能放電(dian)(dian)多長時間；

（4）組(zu)間電(dian)池(chi)(chi)放(fang)電(dian)電(dian)流(liu)不(bu)均衡。各組(zu)電(dian)池(chi)(chi)將根(gen)據自身(shen)情況自然分攤系統(tong)的負荷電(dian)流(liu)來(lai)放(fang)電(dian)，落后(hou)電(dian)池(chi)(chi)組(zu)，內阻(zu)大，分攤電(dian)流(liu)小(xiao)，而健康(kang)電(dian)池(chi)(chi)組(zu)，內阻(zu)低，分攤電(dian)流(liu)大，造成(cheng)某些落后(hou)電(dian)池(chi)(chi)因放(fang)電(dian)電(dian)流(liu)不(bu)夠大而無(wu)法(fa)暴(bao)露(lu)出來(lai)的現象，達(da)不(bu)到我們進(jin)行放(fang)電(dian)性能質量檢測目的。

綜上所述，在(zai)中心機房蓄電(dian)(dian)池必須定期進(jin)行容(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)的(de)(de)需求下，目前兩種容(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)方(fang)法(fa)，各有特(te)點又各有弊端，離線放電(dian)(dian)方(fang)法(fa)固(gu)然可(ke)以達(da)到蓄電(dian)(dian)池容(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)的(de)(de)目的(de)(de)，但是(shi)工作(zuo)量(liang)(liang)太大，系(xi)統安(an)全性偏低(di)，而在(zai)線評(ping)估式放電(dian)(dian)方(fang)法(fa)固(gu)然工作(zuo)量(liang)(liang)比較小，但是(shi)系(xi)統安(an)全性低(di)，達(da)不(bu)到蓄電(dian)(dian)池容(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)的(de)(de)目的(de)(de)，潛伏(fu)的(de)(de)安(an)全隱患(huan)大。因此，當前的(de)(de)蓄電(dian)(dian)池容(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)方(fang)法(fa)必須改革，現將引進(jin)一種全新的(de)(de)、科學(xue)的(de)(de)容(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)技術——全在(zai)線放電(dian)(dian)技術，以使(shi)電(dian)(dian)池放電(dian)(dian)容(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)達(da)到預(yu)期維(wei)護(hu)質量(liang)(liang)檢測(ce)(ce)(ce)效(xiao)果，電(dian)(dian)池放電(dian)(dian)維(wei)護(hu)操縱簡(jian)便安(an)全，進(jin)步了維(wei)護(hu)工作(zuo)效(xiao)率易(yi)得到有效(xiao)的(de)(de)落實。

2、全在線放電技術分析

全(quan)(quan)在(zai)線(xian)放電(dian)(dian)技術(shu)指被測(ce)電(dian)(dian)池(chi)組(zu)通(tong)過串接電(dian)(dian)池(chi)組(zu)全(quan)(quan)在(zai)線(xian)放電(dian)(dian)測(ce)試(shi)(shi)設備(bei)提升在(zai)線(xian)供電(dian)(dian)電(dian)(dian)壓，以自動穩流或恒(heng)功(gong)率控(kong)制(zhi)輸出，使被測(ce)電(dian)(dian)池(chi)組(zu)對在(zai)線(xian)負載設備(bei)進行(xing)供電(dian)(dian)，實(shi)現(xian)被測(ce)電(dian)(dian)池(chi)組(zu)恒(heng)電(dian)(dian)放逐電(dian)(dian)測(ce)試(shi)(shi)或恒(heng)功(gong)率放電(dian)(dian)測(ce)試(shi)(shi)，達到安全(quan)(quan)節能維護(hu)效果。

3、在線放電技術與當前放電技術對比分析

3.2與在線評估式放電技術對比分析
