【蓄(xu)(xu)電(dian)池(chi)容(rong)量】蓄(xu)(xu)電(dian)池(chi)容(rong)量計(ji)算公(gong)式 蓄(xu)(xu)電(dian)池(chi)容(rong)量測試新技術(shu)介紹

蓄電池容量計算公式

容量=放電電流(liu)×放電時間(jian)

蓄電(dian)(dian)(dian)池的(de)(de)容量與放電(dian)(dian)(dian)電(dian)(dian)(dian)流大(da)小及電(dian)(dian)(dian)解液(ye)(ye)的(de)(de)溫度有(you)關，因此標稱容量是在(zai)一定(ding)的(de)(de)放電(dian)(dian)(dian)電(dian)(dian)(dian)流、一定(ding)的(de)(de)終止電(dian)(dian)(dian)壓和一定(ding)的(de)(de)電(dian)(dian)(dian)解液(ye)(ye)溫度下(xia)取得(de)的(de)(de)，標容量有(you)兩(liang)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 ℃的情況下(xia)，以20小時率放電(dian)的電(dian)流（相當于額定(ding)容量的1/20）連續放電至單體1.75V時輸(shu)出的電量。

起動容量

常溫起動容量：指電解液溫度為30 ℃時，以5min率放電(dian)電(dian)流（3倍(bei)額(e)定容量電(dian)流）連續放電(dian)至規定的終(zhong)止電(dian)壓(ya)（6V蓄電池為4.5V，12V蓄電池為9V）時，所(suo)輸出的電(dian)(dian)量，其放電(dian)(dian)持續時間應在5min以上

低溫起動容量：電解液溫度為-18℃時，以3倍(bei)額定容量的(de)電流連續放電至規定終止電壓（12V蓄(xu)電池為6V，6V蓄電池為3V）時所放出的電量，其放電持續(xu)時間應(ying)在2.5min以上。

蓄電池容量測試新技術介紹

通(tong)訊后備(bei)蓄電(dian)(dian)池(chi)質量是通(tong)訊網絡供(gong)電(dian)(dian)不中(zhong)斷的重(zhong)要保障，是整個通(tong)訊電(dian)(dian)源設(she)備(bei)供(gong)電(dian)(dian)保障，保證通(tong)訊網絡正(zheng)常運行的最后一道(dao)防線。根據(ju)蓄電(dian)(dian)池(chi)特(te)性(xing)和維護要求，蓄電(dian)(dian)池(chi)放電(dian)(dian)容量測試(shi)工作是必不可少的。

隨著通訊網絡(luo)規(gui)模的(de)(de)迅猛發展，現網電源(yuan)維護(hu)專業技(ji)術(shu)職員相對較少，當前(qian)電池放電容量測(ce)試(shi)方(fang)式存在安(an)全隱(yin)患，操縱復雜(za)，測(ce)試(shi)工(gong)作(zuo)量大(da)的(de)(de)題目，致使維護(hu)規(gui)程要(yao)求(qiu)的(de)(de)電池放電測(ce)試(shi)工(gong)作(zuo)得(de)(de)不到(dao)有效落(luo)實(shi)，落(luo)后電池不能及時得(de)(de)到(dao)預警和(he)維護(hu)，在用電池往往被提前(qian)報廢，造成(cheng)資源(yuan)浪費。

團體公司、福建公司針(zhen)對電(dian)池(chi)放電(dian)技(ji)(ji)術聯合進(jin)行研究，導進(jin)了(le)創新性的全在線電(dian)池(chi)放電(dian)技(ji)(ji)術，全面解決了(le)幾十年(nian)來原電(dian)池(chi)放電(dian)技(ji)(ji)術中(zhong)存在的安全隱(yin)患題目。

1、當前電池放電技術分析

1.1離線式放電法技術分析

（1）將其中(zhong)一(yi)(yi)組電池(chi)脫離系統后，一(yi)(yi)旦市電中(zhong)斷，系統備用電池(chi)供電時(shi)間明顯(xian)縮短，何況此時(shi)尚(shang)不清楚另一(yi)(yi)組在線(xian)電池(chi)是否存在質(zhi)量(liang)題目，此放電方式事故風險(xian)性高。如要用此方式放電，建議提(ti)前啟用發動機組，并確保發電機組、開關電源等設(she)備能正常運(yun)行，保證安全；

（2）離(li)線放電(dian)(dian)結束后(hou)(hou)的電(dian)(dian)池(chi)組與在線電(dian)(dian)池(chi)組間存在較大電(dian)(dian)壓差，若操(cao)縱(zong)不當(dang)將(jiang)引起開(kai)關電(dian)(dian)源和(he)在線電(dian)(dian)池(chi)組對離(li)線放電(dian)(dian)后(hou)(hou)的電(dian)(dian)池(chi)組進行大電(dian)(dian)流(liu)充電(dian)(dian)，產生(sheng)巨大火花(hua)(hua)，易發生(sheng)安全事故。用此方(fang)式放電(dian)(dian)，需(xu)要配備一臺整(zheng)組智(zhi)能充電(dian)(dian)機，對該離(li)線電(dian)(dian)池(chi)組先(xian)充電(dian)(dian)恢復后(hou)(hou)再并聯回系統(tong)(tong)，以解決打火花(hua)(hua)題(ti)目，這樣將(jiang)使系統(tong)(tong)更長(chang)時間處于單組供(gong)電(dian)(dian)狀態，事故風險高。另通過調整(zheng)整(zheng)流(liu)器輸出與被放電(dian)(dian)的電(dian)(dian)池(chi)組電(dian)(dian)壓相等后(hou)(hou)進行恢復連(lian)接。上述操(cao)縱(zong)一定要謹慎操(cao)縱(zong)；

（3）此放電(dian)方式操(cao)縱時(shi)既要脫(tuo)離(li)電(dian)池組(zu)的正(zheng)極，又要脫(tuo)離(li)電(dian)池組(zu)的負極，尤(you)其是脫(tuo)離(li)電(dian)池組(zu)負極時(shi)需(xu)要特(te)別(bie)小心，操(cao)縱不當引(yin)起負極短路，將造成系統供(gong)電(dian)中斷，導致通訊事故的發生；

（4）此方(fang)式(shi)是將電池(chi)通過(guo)假負載以(yi)熱(re)量形式(shi)消耗(hao)，浪費電能，影響機房(fang)設備運行(xing)環境，需(xu)要(yao)維護職員時刻守護以(yi)免高(gao)溫引發(fa)事故。

1.2在線評估式放電法技術分析

（1）調整(zheng)整(zheng)流(liu)器輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)至(zhi)保(bao)護(hu)低(di)壓(ya)值（如46V），使所有(you)后(hou)備(bei)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)直(zhi)接對(dui)實際(ji)負荷進(jin)行放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)至(zhi)整(zheng)流(liu)器輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)保(bao)護(hu)設(she)(she)置值。由(you)于現網系(xi)統設(she)(she)備(bei)盡大多數電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)配置后(hou)備(bei)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)時間(jian)(jian)為(wei)1～4h，放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)大，應考慮電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)至(zhi)設(she)(she)備(bei)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)回路壓(ya)降及(ji)設(she)(she)備(bei)低(di)壓(ya)工作門限，以及(ji)保(bao)證(zheng)系(xi)統供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)安全，在(zai)(zai)線評(ping)估式放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)其調整(zheng)整(zheng)流(liu)器輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不答應過低(di)（如46V），放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)深(shen)度(du)有(you)限，對(dui)實際(ji)負載的(de)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)時間(jian)(jian)把握比較困難(nan)，評(ping)估電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)量難(nan)以正確，對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)性能(neng)測試有(you)不確定因素存在(zai)(zai)，從而對(dui)保(bao)持電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)活性這一(yi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)測試目(mu)的(de)難(nan)以達(da)到(dao)維護(hu)預期(qi)工作效果；

（2）假如兩(liang)組(zu)電(dian)池(chi)都有失容或欠容、落后等質(zhi)量題(ti)目，當其放(fang)(fang)電(dian)至(zhi)整流器輸出保護值的時(shi)間，不(bu)易被維(wei)護職員及時(shi)發現，此時(shi)可能后備電(dian)池(chi)容量所剩(sheng)無幾，存在(zai)高風險。在(zai)此情況(kuang)下，此放(fang)(fang)電(dian)方式比離線放(fang)(fang)電(dian)方式安全性更低(di)；

（3）由于放(fang)(fang)電(dian)深度有限(xian)，對保(bao)持電(dian)池組的(de)(de)活(huo)性(xing)(xing)這(zhe)一(yi)放(fang)(fang)電(dian)測試的(de)(de)目的(de)(de)無法達到，更為關(guan)鍵的(de)(de)是在全容(rong)量放(fang)(fang)電(dian)的(de)(de)實踐中我們經常發現有些(xie)電(dian)池組在放(fang)(fang)電(dian)前期表現正(zheng)常，但到中后(hou)期，有些(xie)落后(hou)電(dian)池才開始逐(zhu)步暴露出來。這(zhe)一(yi)部分落后(hou)單體，于此(ci)(ci)(ci)放(fang)(fang)電(dian)方式的(de)(de)深度不夠而沒有被發現。所以我們稱此(ci)(ci)(ci)放(fang)(fang)電(dian)方式為在線(xian)評(ping)估(gu)(gu)式，它只能大(da)致(zhi)評(ping)估(gu)(gu)電(dian)池組性(xing)(xing)能，或檢(jian)測此(ci)(ci)(ci)電(dian)池組可以放(fang)(fang)電(dian)至此(ci)(ci)(ci)保(bao)護電(dian)壓(ya)的(de)(de)時間(jian)(jian)是非，而無法進一(yi)步檢(jian)查除此(ci)(ci)(ci)時間(jian)(jian)外究竟還能放(fang)(fang)電(dian)多長(chang)時間(jian)(jian)；

（4）組間電(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)不均衡(heng)。各(ge)組電(dian)(dian)(dian)池(chi)將根(gen)據自身情況自然(ran)分(fen)攤(tan)系統(tong)的負荷電(dian)(dian)(dian)流(liu)來(lai)放電(dian)(dian)(dian)，落(luo)后電(dian)(dian)(dian)池(chi)組，內(nei)阻(zu)大(da)，分(fen)攤(tan)電(dian)(dian)(dian)流(liu)小，而健康電(dian)(dian)(dian)池(chi)組，內(nei)阻(zu)低，分(fen)攤(tan)電(dian)(dian)(dian)流(liu)大(da)，造(zao)成某些(xie)落(luo)后電(dian)(dian)(dian)池(chi)因放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)不夠大(da)而無法暴露出來(lai)的現(xian)象(xiang)，達不到我(wo)們進行(xing)放電(dian)(dian)(dian)性能質量(liang)檢測目(mu)的。

綜上所述，在(zai)中心機房蓄(xu)電(dian)池(chi)必(bi)須定期進(jin)行容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)的(de)(de)需(xu)求(qiu)下，目前(qian)兩種(zhong)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)方(fang)法，各有特點又各有弊(bi)端，離線(xian)放(fang)電(dian)方(fang)法固(gu)然可以達到(dao)(dao)(dao)蓄(xu)電(dian)池(chi)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)的(de)(de)目的(de)(de)，但是工(gong)作量(liang)(liang)(liang)太大，系統安全(quan)(quan)(quan)性(xing)偏低(di)，而在(zai)線(xian)評估式(shi)放(fang)電(dian)方(fang)法固(gu)然工(gong)作量(liang)(liang)(liang)比較小，但是系統安全(quan)(quan)(quan)性(xing)低(di)，達不到(dao)(dao)(dao)蓄(xu)電(dian)池(chi)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)的(de)(de)目的(de)(de)，潛伏(fu)的(de)(de)安全(quan)(quan)(quan)隱患大。因(yin)此，當前(qian)的(de)(de)蓄(xu)電(dian)池(chi)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)方(fang)法必(bi)須改革，現將引(yin)進(jin)一種(zhong)全(quan)(quan)(quan)新的(de)(de)、科學的(de)(de)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)技(ji)術——全(quan)(quan)(quan)在(zai)線(xian)放(fang)電(dian)技(ji)術，以使電(dian)池(chi)放(fang)電(dian)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)達到(dao)(dao)(dao)預期維(wei)護(hu)(hu)質量(liang)(liang)(liang)檢測(ce)效(xiao)果，電(dian)池(chi)放(fang)電(dian)維(wei)護(hu)(hu)操縱(zong)簡便安全(quan)(quan)(quan)，進(jin)步了維(wei)護(hu)(hu)工(gong)作效(xiao)率易得到(dao)(dao)(dao)有效(xiao)的(de)(de)落實(shi)。

2、全在線放電技術分析

3、在線放電技術與當前放電技術對比分析

3.1與離線放電技術對比分析

（1）放(fang)電(dian)過程(cheng)最大限度(du)保證電(dian)池組備用電(dian)能，最大限度(du)降(jiang)低放(fang)電(dian)測(ce)試造成(cheng)系(xi)統癱(tan)瘓的風險；

（4）僅在(zai)電(dian)池組的(de)正極(ji)進行(xing)無縫連接(jie)操縱(zong)，避免了離線放(fang)電(dian)因(yin)操縱(zong)不當引起的(de)短路風險；

（5）該設備一旦串聯(lian)接(jie)進(jin)(jin)電池組的正極(ji)，設定相(xiang)關(guan)放電參數后，所有放電充(chong)電工(gong)(gong)(gong)作(zuo)自動完成，維護(hu)職員(yuan)可以進(jin)(jin)行其它工(gong)(gong)(gong)作(zuo)，降低工(gong)(gong)(gong)作(zuo)強(qiang)度，進(jin)(jin)步(bu)工(gong)(gong)(gong)作(zuo)效率。

3.2與在線評估式放電技術對比分析

（1）全在線(xian)放(fang)電(dian)方式(shi)能夠達到深度放(fang)電(dian)保持電(dian)池活性及檢(jian)測落后(hou)電(dian)池的(de)放(fang)電(dian)測試目的(de)，充分把握電(dian)池組剩余(yu)容量和(he)后(hou)備供電(dian)時間；
