閥控式密封鉛酸蓄電池的應(yīng)用與維護(hù)

作者: 時(shí)間:2011-02-13 來源:網(wǎng)絡(luò) 收藏

放出電池容量計(jì)算:

[電流(A)×時(shí)間(h)/電池額定容量(Ah)]×100%

  在相應(yīng)放出容量下,其單體電池電壓值應(yīng)等于或大于相應(yīng)電壓值,即電池容量正常,反之電池容量不足。

  電池組放電后,應(yīng)立即轉(zhuǎn)入充電,開始時(shí)可控制電流不大于0.2C(A)為宜(如200Ah電池,充電電流應(yīng)不大于0.2×200=40A)。當(dāng)電流變小時(shí),可慢慢提高電池組充電電壓,達(dá)到均充電壓值,再充6小時(shí),然后再調(diào)回浮充電壓值。

 ?、鄹鶕?jù)治療性充放電過程,從放電容量和電池電壓值判斷每只電池的“健康情況”,因?yàn)椴煌烹娙萘窟^程中每只電池的電壓變化,就代表了該電池的“健康”狀況,如有不合格電池,應(yīng)采取補(bǔ)救措施。

  下面,提供某電信局使用POWERSON牌48V-2000Ah電池組的一種記錄表格(見表4)。從表4中數(shù)據(jù)分析可對(duì)電池正常與否作出判斷,并采取合適的方法:

  S電池運(yùn)行基本正常,但6號(hào)電池容量偏低,注意跟蹤。

  S整個(gè)電池組容量稍低于標(biāo)準(zhǔn)值,其原因是電池未完全充足。

S浮充電壓偏低,應(yīng)提高到53.7V(28℃)。

  S應(yīng)進(jìn)行均充充電,以提高落后電池電壓。

  總而言之,在推廣VRLAB的過程中,制造商應(yīng)嚴(yán)格控制生產(chǎn)工藝條件,提供性能一致的高質(zhì)量電池產(chǎn)品;用戶應(yīng)加強(qiáng)對(duì)VRLAB的了解,并做好必要的維護(hù)工作,共同發(fā)展我國VRLAB民族工業(yè),為我國國民經(jīng)濟(jì)做出更大的貢獻(xiàn)。
