【蓄(xu)電(dian)池(chi)容量】蓄(xu)電(dian)池(chi)容量計算公式(shi) 蓄(xu)電(dian)池(chi)容量測試(shi)新技術介紹

蓄電池容量計算公式

容量=放(fang)電(dian)電(dian)流×放(fang)電(dian)時間

蓄電(dian)(dian)池的(de)(de)容量(liang)與放電(dian)(dian)電(dian)(dian)流大小(xiao)及電(dian)(dian)解(jie)液的(de)(de)溫度有關，因此標稱容量(liang)是在一(yi)定的(de)(de)放電(dian)(dian)電(dian)(dian)流、一(yi)定的(de)(de)終止電(dian)(dian)壓和一(yi)定的(de)(de)電(dian)(dian)解(jie)液溫度下取得(de)的(de)(de)，標容量(liang)有兩種。

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 ℃的情(qing)況(kuang)下，以20小時率(lv)放(fang)電(dian)的(de)電(dian)流（相(xiang)當(dang)于額(e)定容量的(de)1/20）連續放電至單(dan)體1.75V時輸出的(de)電量(liang)。

起動容量

常溫起動容量：指電解液溫度為30 ℃時，以5min率(lv)放電電流(liu)（3倍(bei)額定(ding)容量電流）連續(xu)放電至規定(ding)的終止電壓（6V蓄電池為(wei)4.5V，12V蓄電池(chi)為9V）時，所輸出的電量，其(qi)放電持續(xu)時間(jian)應在5min以上(shang)

低溫起動容量：電解液溫度為-18℃時，以3倍額定容量(liang)的電(dian)流連續放電(dian)至規(gui)定終止電(dian)壓（12V蓄電池為6V，6V蓄電(dian)池為3V）時所放出的電(dian)量，其放電(dian)持續時間應(ying)在2.5min以上。

蓄電池容量測試新技術介紹

通訊(xun)后(hou)備蓄(xu)電(dian)(dian)池質量(liang)是通訊(xun)網(wang)絡供電(dian)(dian)不中斷的重要保(bao)障，是整個通訊(xun)電(dian)(dian)源設備供電(dian)(dian)保(bao)障，保(bao)證通訊(xun)網(wang)絡正常運(yun)行的最后(hou)一(yi)道(dao)防線。根據蓄(xu)電(dian)(dian)池特性和維護要求(qiu)，蓄(xu)電(dian)(dian)池放電(dian)(dian)容量(liang)測試工(gong)作是必不可(ke)少的。

隨著通訊(xun)網(wang)絡規模的(de)迅猛(meng)發展(zhan)，現(xian)網(wang)電(dian)源維護(hu)專業技術職(zhi)員相對較少，當前(qian)電(dian)池(chi)放(fang)電(dian)容量測(ce)試方式存(cun)在安全隱患(huan)，操(cao)縱復雜(za)，測(ce)試工作量大(da)的(de)題目，致使維護(hu)規程要求的(de)電(dian)池(chi)放(fang)電(dian)測(ce)試工作得不(bu)到(dao)有效落實(shi)，落后電(dian)池(chi)不(bu)能及(ji)時(shi)得到(dao)預警(jing)和維護(hu)，在用電(dian)池(chi)往往被提前(qian)報廢，造成資源浪費。

團體公(gong)司、福建公(gong)司針對(dui)電(dian)池(chi)放電(dian)技術聯合進(jin)行研究，導進(jin)了(le)創(chuang)新性的(de)全在(zai)線(xian)電(dian)池(chi)放電(dian)技術，全面解決了(le)幾十年來原電(dian)池(chi)放電(dian)技術中存在(zai)的(de)安全隱患題目。

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(qi)中(zhong)一(yi)組(zu)(zu)(zu)(zu)電池(chi)脫(tuo)離(li)系(xi)統后，一(yi)旦市電中(zhong)斷，系(xi)統備用電池(chi)供電時間明顯縮(suo)短，何況此(ci)時尚不(bu)清楚另一(yi)組(zu)(zu)(zu)(zu)在線電池(chi)是否存在質量題目，此(ci)放(fang)電方(fang)式事故風險性高。如要(yao)用此(ci)方(fang)式放(fang)電，建議提前啟用發動機組(zu)(zu)(zu)(zu)，并確保發電機組(zu)(zu)(zu)(zu)、開關(guan)電源等設備能正常運(yun)行，保證安全；

（2）離線放(fang)(fang)電(dian)(dian)(dian)(dian)結束后的(de)電(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)(zu)(zu)(zu)(zu)與在(zai)線電(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)(zu)(zu)(zu)(zu)間存在(zai)較大電(dian)(dian)(dian)(dian)壓差，若操(cao)縱不當將(jiang)引(yin)起開關電(dian)(dian)(dian)(dian)源和在(zai)線電(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)(zu)(zu)(zu)(zu)對離線放(fang)(fang)電(dian)(dian)(dian)(dian)后的(de)電(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)(zu)(zu)(zu)(zu)進行大電(dian)(dian)(dian)(dian)流充電(dian)(dian)(dian)(dian)，產生(sheng)巨大火花，易發(fa)生(sheng)安(an)全(quan)事故。用此(ci)方(fang)式放(fang)(fang)電(dian)(dian)(dian)(dian)，需(xu)要(yao)配(pei)備(bei)一(yi)(yi)臺整組(zu)(zu)(zu)(zu)(zu)(zu)智(zhi)能充電(dian)(dian)(dian)(dian)機(ji)，對該離線電(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)(zu)(zu)(zu)(zu)先充電(dian)(dian)(dian)(dian)恢復后再并聯回系統(tong)，以解決打(da)火花題(ti)目，這(zhe)樣將(jiang)使(shi)系統(tong)更(geng)長時間處于單(dan)組(zu)(zu)(zu)(zu)(zu)(zu)供電(dian)(dian)(dian)(dian)狀(zhuang)態(tai)，事故風險(xian)高。另通(tong)過調(diao)整整流器輸(shu)出(chu)與被(bei)放(fang)(fang)電(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)(zu)(zu)(zu)(zu)電(dian)(dian)(dian)(dian)壓相等后進行恢復連接。上(shang)述操(cao)縱一(yi)(yi)定(ding)要(yao)謹慎操(cao)縱；

（3）此放電方式操(cao)縱時(shi)(shi)既要脫離電池組的(de)(de)正(zheng)極，又要脫離電池組的(de)(de)負(fu)(fu)極，尤其(qi)是脫離電池組負(fu)(fu)極時(shi)(shi)需要特別(bie)小(xiao)心，操(cao)縱不當引起負(fu)(fu)極短(duan)路，將造成系統供電中斷，導致通訊事故(gu)的(de)(de)發生；

（4）此(ci)方式是(shi)將電池通過假負載以(yi)熱量形式消耗，浪費電能，影(ying)響(xiang)機房設(she)備運行(xing)環境，需要維護(hu)職員時刻守護(hu)以(yi)免高溫引發(fa)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)(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)至(zhi)保(bao)護低壓(ya)(ya)值（如46V），使所有(you)(you)后備(bei)電(dian)(dian)(dian)(dian)池(chi)(chi)組直接對實際負荷進行(xing)放(fang)(fang)電(dian)(dian)(dian)(dian)至(zhi)整(zheng)流器(qi)輸(shu)(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)保(bao)護設(she)置值。由(you)于現(xian)網系(xi)統設(she)備(bei)盡大(da)多(duo)數電(dian)(dian)(dian)(dian)池(chi)(chi)配置后備(bei)供電(dian)(dian)(dian)(dian)時間(jian)為1～4h，放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流大(da)，應考(kao)慮電(dian)(dian)(dian)(dian)池(chi)(chi)組至(zhi)設(she)備(bei)供電(dian)(dian)(dian)(dian)回路(lu)壓(ya)(ya)降及(ji)設(she)備(bei)低壓(ya)(ya)工(gong)作門(men)限(xian)，以及(ji)保(bao)證(zheng)系(xi)統供電(dian)(dian)(dian)(dian)安全，在線評估式(shi)放(fang)(fang)電(dian)(dian)(dian)(dian)其調整(zheng)整(zheng)流器(qi)輸(shu)(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)不答應過低（如46V），放(fang)(fang)電(dian)(dian)(dian)(dian)深度有(you)(you)限(xian)，對實際負載的放(fang)(fang)電(dian)(dian)(dian)(dian)時間(jian)把握比較困難(nan)，評估電(dian)(dian)(dian)(dian)池(chi)(chi)容量難(nan)以正確，對電(dian)(dian)(dian)(dian)池(chi)(chi)性(xing)能測試有(you)(you)不確定因素存在，從而(er)對保(bao)持電(dian)(dian)(dian)(dian)池(chi)(chi)組活(huo)性(xing)這一放(fang)(fang)電(dian)(dian)(dian)(dian)測試目的難(nan)以達到維護預期工(gong)作效果(guo)；

（2）假如(ru)兩(liang)組電(dian)池都有失容(rong)或欠容(rong)、落后等(deng)質(zhi)量題目，當(dang)其放(fang)電(dian)至整流器輸出保護值的(de)時間，不易(yi)被(bei)維(wei)護職員及(ji)時發現，此時可能后備(bei)電(dian)池容(rong)量所剩無幾，存在高(gao)風險。在此情(qing)況下，此放(fang)電(dian)方(fang)式比(bi)離(li)線放(fang)電(dian)方(fang)式安全(quan)性更低；

（3）由(you)于放(fang)電(dian)(dian)(dian)(dian)(dian)深(shen)度(du)有限(xian)，對保持(chi)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組的(de)活性(xing)這一放(fang)電(dian)(dian)(dian)(dian)(dian)測(ce)試的(de)目的(de)無法達到，更(geng)為(wei)關鍵的(de)是(shi)在全容量放(fang)電(dian)(dian)(dian)(dian)(dian)的(de)實踐中(zhong)我們(men)經常(chang)發(fa)(fa)現有些(xie)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組在放(fang)電(dian)(dian)(dian)(dian)(dian)前期(qi)表現正(zheng)常(chang)，但到中(zhong)后期(qi)，有些(xie)落后電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)才開(kai)始(shi)逐(zhu)步(bu)暴露出來。這一部(bu)分落后單體，于此(ci)(ci)(ci)放(fang)電(dian)(dian)(dian)(dian)(dian)方式的(de)深(shen)度(du)不夠而沒有被發(fa)(fa)現。所(suo)以我們(men)稱此(ci)(ci)(ci)放(fang)電(dian)(dian)(dian)(dian)(dian)方式為(wei)在線(xian)評(ping)估式，它只(zhi)能(neng)(neng)大致(zhi)評(ping)估電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組性(xing)能(neng)(neng)，或檢測(ce)此(ci)(ci)(ci)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組可以放(fang)電(dian)(dian)(dian)(dian)(dian)至(zhi)此(ci)(ci)(ci)保護電(dian)(dian)(dian)(dian)(dian)壓的(de)時間是(shi)非，而無法進一步(bu)檢查除此(ci)(ci)(ci)時間外(wai)究竟還(huan)能(neng)(neng)放(fang)電(dian)(dian)(dian)(dian)(dian)多(duo)長(chang)時間；

（4）組(zu)間電(dian)(dian)(dian)池放電(dian)(dian)(dian)電(dian)(dian)(dian)流不(bu)均(jun)衡(heng)。各組(zu)電(dian)(dian)(dian)池將根據自(zi)(zi)身(shen)情(qing)況自(zi)(zi)然(ran)分(fen)攤系統的(de)負荷(he)電(dian)(dian)(dian)流來(lai)放電(dian)(dian)(dian)，落(luo)后電(dian)(dian)(dian)池組(zu)，內阻大(da)，分(fen)攤電(dian)(dian)(dian)流小，而(er)健康電(dian)(dian)(dian)池組(zu)，內阻低，分(fen)攤電(dian)(dian)(dian)流大(da)，造成(cheng)某些落(luo)后電(dian)(dian)(dian)池因放電(dian)(dian)(dian)電(dian)(dian)(dian)流不(bu)夠大(da)而(er)無法暴露出(chu)來(lai)的(de)現象(xiang)，達不(bu)到(dao)我們(men)進行(xing)放電(dian)(dian)(dian)性能質量檢測目的(de)。

綜上所(suo)述(shu)，在(zai)中心機房蓄(xu)電(dian)池必(bi)須定期進(jin)行容(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)(shi)的(de)(de)需求(qiu)下(xia)，目前兩(liang)種(zhong)容(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)(shi)方(fang)法(fa)，各有(you)特點又各有(you)弊端，離(li)線(xian)放(fang)電(dian)方(fang)法(fa)固(gu)(gu)然可以達到蓄(xu)電(dian)池容(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)(shi)的(de)(de)目的(de)(de)，但是工作(zuo)量(liang)(liang)(liang)太大，系(xi)統安全(quan)性偏(pian)低，而在(zai)線(xian)評估式放(fang)電(dian)方(fang)法(fa)固(gu)(gu)然工作(zuo)量(liang)(liang)(liang)比(bi)較小，但是系(xi)統安全(quan)性低，達不到蓄(xu)電(dian)池容(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)(shi)的(de)(de)目的(de)(de)，潛伏的(de)(de)安全(quan)隱患大。因此，當前的(de)(de)蓄(xu)電(dian)池容(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)(shi)方(fang)法(fa)必(bi)須改革，現將引進(jin)一種(zhong)全(quan)新的(de)(de)、科學(xue)的(de)(de)容(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)(shi)技(ji)術——全(quan)在(zai)線(xian)放(fang)電(dian)技(ji)術，以使電(dian)池放(fang)電(dian)容(rong)(rong)量(liang)(liang)(liang)測(ce)試(shi)(shi)達到預期維護(hu)質量(liang)(liang)(liang)檢(jian)測(ce)效果，電(dian)池放(fang)電(dian)維護(hu)操縱簡便安全(quan)，進(jin)步了維護(hu)工作(zuo)效率(lv)易得到有(you)效的(de)(de)落(luo)實。

2、全在線放電技術分析

2.2在線放電“無縫連接”技術

為確(que)保電(dian)池(chi)放(fang)電(dian)測試的(de)安全性(xing)，電(dian)池(chi)組全在(zai)線放(fang)電(dian)設備在(zai)串聯(lian)接進(jin)電(dian)池(chi)組正極時要(yao)求(qiu)以(yi)無(wu)縫連接方(fang)式，如(ru)圖5所示。

電(dian)池組在線放(fang)電(dian)測試(shi)無(wu)縫連接(jie)操縱，“設備”接(jie)進應遵守“先接(jie)三，后拆(chai)(chai)一”，即為(wei)先接(jie)電(dian)源線L1、L2、L3，后拆(chai)(chai)原電(dian)源連接(jie)線L5；“設備”成(cheng)測試(shi)退出(chu)服(fu)務(wu)，應遵守“先接(jie)一，后拆(chai)(chai)三”的原則，即為(wei)先接(jie)原電(dian)源連接(jie)線L5，后拆(chai)(chai)電(dian)源線L1、L2、L3。
