  2019-6-19 直流屏的調試方法

  1、首先檢查一次和二次回路接線是否正確-主要(yao)是查致命錯誤(wu)，比如說弱點接口接上(shang)強電(dian)了，應該接入直流(liu)(liu)信(xin)號卻接入交(jiao)流(liu)(liu)信(xin)號了，還(huan)有(you)就是短路問題。 2、避(bi)免了以上(shang)的(de)原因，斷(duan)開所有(you)的(de)斷(duan)路器(qi)和保(bao)險，接通交(jiao)流(liu)(liu)電(dian)源，測試交(jiao)流(liu)(liu)雙(shuang)電(dian)源切換(huan)裝置是否工(gong)作正常(chang)，雙(shuang)電(dian)...
