在電(dian)(dian)(dian)(dian)力中(zhong)斷時，蓄(xu)(xu)電(dian)(dian)(dian)(dian)池作為(wei)備用電(dian)(dian)(dian)(dian)源在直流系統中(zhong)起著(zhu)極(ji)其重要(yao)的(de)作用，許多(duo)重要(yao)的(de)設(she)備必(bi)須靠蓄(xu)(xu)電(dian)(dian)(dian)(dian)池來(lai)維護運(yun)行。但(dan)是在蓄(xu)(xu)電(dian)(dian)(dian)(dian)池預壽命到達之前，它的(de)容量由于種種原因(yin)回發生顯著(zhu)的(de)下降。因(yin)此蓄(xu)(xu)電(dian)(dian)(dian)(dian)池的(de)容量必(bi)須定時檢(jian)測，避免在電(dian)(dian)(dian)(dian)力事故停電(dian)(dian)(dian)(dian)時給您帶來(lai)慘重的(de)經濟損失(shi)。
