直流屏主要是為開關柜，綜合保護裝置等提供操作電源或者控制電源；直流屏是將交流電整流為直流電，為外界負載供電。

直流屏的調試,接(jie)通交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)測試(shi)交(jiao)流(liu)雙電(dian)(dian)(dian)(dian)(dian)源(yuan)切換(huan)裝置(zhi)是否工作正(zheng)(zheng)常，雙電(dian)(dian)(dian)(dian)(dian)源(yuan)切換(huan)裝置(zhi)的下口(kou)電(dian)(dian)(dian)(dian)(dian)壓(ya)是否正(zheng)(zheng)常。交(jiao)流(liu)部分測試(shi)正(zheng)(zheng)常后，依(yi)次閉合(he)充電(dian)(dian)(dian)(dian)(dian)模(mo)塊(kuai)的交(jiao)流(liu)開(kai)關，觀(guan)察模(mo)塊(kuai)是否正(zheng)(zheng)常啟(qi)動并測量模(mo)塊(kuai)輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)和極(ji)(ji)性(xing)。充電(dian)(dian)(dian)(dian)(dian)模(mo)塊(kuai)啟(qi)動正(zheng)(zheng)常并輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)和極(ji)(ji)性(xing)正(zheng)(zheng)確后，接(jie)通電(dian)(dian)(dian)(dian)(dian)池組開(kai)關及各母(mu)線開(kai)關，測量電(dian)(dian)(dian)(dian)(dian)池組開(kai)關下口(kou)、合(he)母(mu)、控母(mu)電(dian)(dian)(dian)(dian)(dian)壓(ya)和極(ji)(ji)性(xing)是否正(zheng)(zheng)確，并觀(guan)察電(dian)(dian)(dian)(dian)(dian)壓(ya)表計是否方向打(da)翻。
