*章 概述

在(zai)(zai)電(dian)力中斷(duan)時(shi)，蓄(xu)電(dian)池(chi)作為備用電(dian)源在(zai)(zai)直流系(xi)統中起(qi)著極其重(zhong)要的作用，許(xu)多重(zhong)要的設備必須靠蓄(xu)電(dian)池(chi)來維護運行。但是(shi)在(zai)(zai)蓄(xu)電(dian)池(chi)預壽命到(dao)達之前，它的容量由于(yu)種(zhong)種(zhong)原(yuan)因回發生顯著的下降。因此蓄(xu)電(dian)池(chi)的容量必須定時(shi)檢測(ce)，避(bi)免在(zai)(zai)電(dian)力事故停電(dian)時(shi)給(gei)您帶來慘重(zhong)的經(jing)濟損失。

為了檢驗蓄電(dian)(dian)池組(zu)的可(ke)備用(yong)時間及實際(ji)容量，保證系統的正常運行，一(yi)般(ban)情況每年(nian)要(yao)對蓄電(dian)(dian)池組(zu)進(jin)行一(yi)次核(he)對性(xing)放(fang)(fang)電(dian)(dian)測試(shi)。判定蓄電(dian)(dian)池容量是否(fou)滿足要(yao)求zui可(ke)信賴的方法(fa)是進(jin)行深度(du)恒流放(fang)(fang)電(dian)(dian)測試(shi)。傳統的蓄電(dian)(dian)池放(fang)(fang)電(dian)(dian)測試(shi)一(yi)般(ban)使用(yong)笨重(zhong)的電(dian)(dian)阻箱，需要(yao)人工調節放(fang)(fang)電(dian)(dian)電(dian)(dian)流，控制精度(du)低，工作繁復，勞動強度(du)大(da)。
