ST808蓄電池放電檢測儀

 概述(shu)

在(zai)(zai)電(dian)力中(zhong)斷時(shi)(shi)，蓄(xu)(xu)電(dian)池作為備用電(dian)源在(zai)(zai)直(zhi)流(liu)系統中(zhong)起著(zhu)極其重要的(de)(de)(de)作用，許多(duo)重要的(de)(de)(de)設(she)備必(bi)須(xu)靠(kao)蓄(xu)(xu)電(dian)池來(lai)維護運行。但是在(zai)(zai)蓄(xu)(xu)電(dian)池預壽(shou)命(ming)到(dao)達之前，它的(de)(de)(de)容量由于種種原因(yin)(yin)回發(fa)生(sheng)顯著(zhu)的(de)(de)(de)下降。因(yin)(yin)此蓄(xu)(xu)電(dian)池的(de)(de)(de)容量必(bi)須(xu)定(ding)時(shi)(shi)檢測，避免在(zai)(zai)電(dian)力事故停電(dian)時(shi)(shi)給您帶來(lai)慘重的(de)(de)(de)經濟損(sun)失。

為了檢驗(yan)蓄(xu)電(dian)池組的可備用時間及實際(ji)容量(liang)，保證系(xi)統的正常運行，一(yi)(yi)般(ban)情況每(mei)年要對蓄(xu)電(dian)池組進行一(yi)(yi)次核對性(xing)放(fang)電(dian)測(ce)試。判定蓄(xu)電(dian)池容量(liang)是(shi)否滿(man)足要求(qiu)z`ui可信賴的 方法(fa)是(shi)進行深度恒流(liu)放(fang)電(dian)測(ce)試。傳統的蓄(xu)電(dian)池放(fang)電(dian)測(ce)試一(yi)(yi)般(ban)使用笨(ben)重的電(dian)阻箱(xiang)，需(xu)要人(ren)工調節放(fang)電(dian)電(dian)流(liu)，控制精度低，工作繁復，勞動強(qiang)度大。
