一、直流屏蓄電池為什么要進行活化

直流屏蓄電池需要定時的進行充放電才能保持活性，直流屏廠家都知道這個道理，但是很多用戶購買了直流屏以后，由于(yu)項目原因直(zhi)流屏(ping)長期(qi)擱(ge)置不用或者直(zhi)流屏(ping)蓄(xu)電(dian)池管理不當(dang)，造成直(zhi)流屏(ping)蓄(xu)電(dian)池失去(qu)活性，這時就需(xu)要進(jin)行蓄(xu)電(dian)池活化(hua)處(chu)理，那么什么是(shi)蓄(xu)電(dian)池活化(hua)呢？

通(tong)常，鉛酸蓄(xu)電池(chi)(chi)由于長(chang)期(qi)擱置不用，或者由于長(chang)期(qi)欠充電，會導致活(huo)性物質(zhi)(zhi)主要是(shi)負極(ji)活(huo)性物質(zhi)(zhi)的硫化(hua)失效，容量衰減，這時，可以進(jin)行幾(ji)次大電流(liu)的充電和(he)放(fang)電以激活(huo)這些硫化(hua)的活(huo)性物質(zhi)(zhi)，這個過程就叫活(huo)化(hua)。直流(liu)屏蓄(xu)電池(chi)(chi)活(huo)化(hua)實際上(shang)就是(shi)電池(chi)(chi)核對性容量試驗(yan)，通(tong)過試驗(yan)來得知電池(chi)(chi)目前的實際保有容量。

二、直流屏蓄電池放電試驗操作方法

直流屏(ping)蓄電(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)試(shi)驗(yan)每半年(nian)進(jin)行一(yi)次(ci)，放(fang)電(dian)(dian)(dian)負荷為(wei)變電(dian)(dian)(dian)站(zhan)實際直流負荷，必要時(shi)(shi)可以加入事(shi)故照明(ming)及逆變負荷。考慮到變電(dian)(dian)(dian)站(zhan)事(shi)故處理的緊迫性，尤其是煤礦(kuang)地面變電(dian)(dian)(dian)站(zhan)，每次(ci)放(fang)電(dian)(dian)(dian)時(shi)(shi)間不得低于2小時(shi)(shi)。蓄電(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)試(shi)驗(yan)應(ying)盡量選擇設(she)備檢(jian)修的時(shi)(shi)間，以避免(mian)因(yin)操作不當(dang)引起(qi)系統(tong)失(shi)電(dian)(dian)(dian)導致機電(dian)(dian)(dian)事(shi)故。

1、將直(zhi)流屏微機監控單元切換到(dao)主界面，選擇(ze)參數(shu)顯示。檢查各(ge)運行參數(shu)均在正常范圍(wei)。

2、將直流(liu)(liu)屏交(jiao)流(liu)(liu)進線開關斷(duan)(duan)開（兩(liang)路，先斷(duan)(duan)備(bei)用再斷(duan)(duan)主(zhu)用，避免不必要的交(jiao)流(liu)(liu)電(dian)源(yuan)自動切(qie)換），高頻開關電(dian)源(yuan)整流(liu)(liu)器(qi)停止工作，蓄電(dian)池(chi)組即刻(ke)不間(jian)斷(duan)(duan)地向(xiang)直流(liu)(liu)母線供電(dian)。同時觀(guan)察(cha)微機監控(kong)單元(yuan)參數顯示界面的變化（電(dian)池(chi)總(zong)電(dian)壓、單只蓄電(dian)池(chi)電(dian)壓、放電(dian)電(dian)流(liu)(liu)）。

3、放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)試驗期間應每隔20分鐘對直流屏巡視記(ji)錄一次，記(ji)錄電(dian)(dian)(dian)(dian)(dian)池總電(dian)(dian)(dian)(dian)(dian)壓(ya)、單只蓄(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)、放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流等(deng)的參數。放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)開(kai)始第一次記(ji)錄時用萬用表或標準電(dian)(dian)(dian)(dian)(dian)壓(ya)表核對一次單體電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)與觸摸(mo)屏顯示的蓄(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)是否相符，以避免傳感器故障造(zao)成的微機監控單元與實際蓄(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)相符。

4、放電試驗期(qi)間應同時檢(jian)查各蓄電池(chi)本體有(you)無(wu)異常(chang)（電池(chi)溫度有(you)無(wu)異常(chang)、有(you)無(wu)鼓包、有(you)無(wu)放電聲響）。

5、放(fang)電試(shi)驗過程(cheng)中(zhong)如有(you)單(dan)只蓄(xu)電池(chi)(chi)的(de)電壓低于11V，應立即停(ting)止放(fang)電試(shi)驗，將交流(liu)進線恢復送電，記錄各項數(shu)據及放(fang)電時間（開始(shi)放(fang)電到終止放(fang)電的(de)時間）。如果有(you)單(dan)只蓄(xu)電池(chi)(chi)低于11V的(de)應該考慮盡早(zao)更(geng)換整套全部(bu)電池(chi)(chi)，以確保(bao)萬無(wu)一失。

6、直流(liu)屏蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)總(zong)(zong)電(dian)(dian)(dian)(dian)(dian)壓放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)如(ru)果(guo)在2小(xiao)時之(zhi)內減少(shao)到205V時（按(an)照廠(chang)家的技術資料要求(qiu)到200V為止(zhi)，考慮(lv)到實際(ji)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)試(shi)驗操作時，為避免(mian)(mian)人員因素發現不(bu)及(ji)時造成過(guo)(guo)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)），應立(li)即(ji)(ji)停止(zhi)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)試(shi)驗，將交流(liu)進(jin)(jin)線恢(hui)復(fu)送電(dian)(dian)(dian)(dian)(dian)，即(ji)(ji)對(dui)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組進(jin)(jin)行充電(dian)(dian)(dian)(dian)(dian)，以(yi)免(mian)(mian)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)過(guo)(guo)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)而損壞，如(ru)果(guo)不(bu)能立(li)即(ji)(ji)恢(hui)復(fu)交流(liu)進(jin)(jin)線供電(dian)(dian)(dian)(dian)(dian)，必須蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組的放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)總(zong)(zong)開(kai)關爭取(qu)在24小(xiao)時內對(dui)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組進(jin)(jin)行充電(dian)(dian)(dian)(dian)(dian)。

記錄放(fang)(fang)電時(shi)間(jian)（開始(shi)放(fang)(fang)電到結束(shu)放(fang)(fang)電的(de)時(shi)間(jian)）、初(chu)始(shi)和(he)終止(zhi)放(fang)(fang)電時(shi)的(de)放(fang)(fang)電電流(liu)。如果出現(xian)上述情(qing)況應該(gai)考慮盡早(zao)更換整(zheng)套全部電池，以確保萬(wan)無(wu)一失。

三、直流屏蓄電池日常維護使用注意事項

1、直流屏調試(shi)運行(xing)(xing)后(hou)(hou)，整流器應(ying)長期(qi)運行(xing)(xing)工作(zuo)，對蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)組(zu)進行(xing)(xing)充(chong)電(dian)(dian)(dian)和對母(mu)線供(gong)電(dian)(dian)(dian)，使(shi)蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)組(zu)保(bao)持滿容量的最佳工作(zuo)狀態，蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)組(zu)不能故意(yi)循(xun)環(huan)放(fang)電(dian)(dian)(dian)使(shi)用(yong)(yong)，以(yi)免蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)組(zu)因使(shi)用(yong)(yong)不當而損壞或大幅降(jiang)低使(shi)用(yong)(yong)壽命（蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)循(xun)環(huan)放(fang)電(dian)(dian)(dian)即(ji):將蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)充(chong)滿后(hou)(hou)停止整流器工作(zuo)，用(yong)(yong)蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)供(gong)母(mu)線負載，蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)到(dao)終止電(dian)(dian)(dian)壓，又給(gei)蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)，如(ru)此循(xun)環(huan)使(shi)用(yong)(yong)。此行(xing)(xing)為會大幅降(jiang)低蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)的使(shi)用(yong)(yong)壽命）。

2、直流(liu)屏(ping)所配蓄(xu)(xu)電池閑置6個月(yue)后（包括(kuo)未安(an)裝及安(an)裝后未運(yun)行的情(qing)況），必(bi)須對(dui)其進行補(bu)充電，以免蓄(xu)(xu)電池組因欠(qian)充而(er)損壞(huai)或大(da)幅降低使(shi)用壽命(ming)。

特別(bie)提(ti)醒：現在很(hen)多變電(dian)站直(zhi)流(liu)屏蓄電(dian)池從安裝(zhuang)投運開始已經三四年(nian)了(le)，由(you)于當時技術力(li)量欠缺或者沒(mei)有(you)仔細(xi)閱(yue)讀直(zhi)流(liu)屏使用說明(ming)書，從來沒(mei)有(you)進行過(guo)蓄電(dian)池的放電(dian)試驗，此(ci)種情況下(xia)，蓄電(dian)池壽命基本上已經大打折扣了(le)。
