3.判斷(duan)是(shi)(shi)道(dao)(dao)(dao)岔室(shi)(shi)(shi)(shi)內(nei)還(huan)是(shi)(shi)室(shi)(shi)(shi)(shi)外的(de)原(yuan)因①如(ru)果(guo)(guo)(guo)是(shi)(shi)單動(dong)(dong)(dong)道(dao)(dao)(dao)岔,在(zai)操(cao)動(dong)(dong)(dong)時控制臺(tai)的(de)電(dian)(dian)流表有(you)指(zhi)示,說(shuo)明(ming)動(dong)(dong)(dong)作道(dao)(dao)(dao)岔的(de)電(dian)(dian)已送至(zhi)到道(dao)(dao)(dao)岔。如(ru)果(guo)(guo)(guo)這時道(dao)(dao)(dao)岔不(bu)(bu)能操(cao)到規定位(wei)置,是(shi)(shi)室(shi)(shi)(shi)(shi)外原(yuan)因。在(zai)操(cao)動(dong)(dong)(dong)道(dao)(dao)(dao)岔時,如(ru)果(guo)(guo)(guo)控制臺(tai)的(de)電(dian)(dian)流表沒有(you)指(zhi)示,首(shou)先到機械室(shi)(shi)(shi)(shi)的(de)室(shi)(shi)(shi)(shi)外分線(xian)盤測量該道(dao)(dao)(dao)岔有(you)沒有(you)電(dian)(dian)壓,如(ru)果(guo)(guo)(guo)有(you)電(dian)(dian)壓說(shuo)明(ming)動(dong)(dong)(dong)作道(dao)(dao)(dao)岔的(de)電(dian)(dian)已送出(chu),是(shi)(shi)室(shi)(shi)(shi)(shi)外故(gu)障(zhang)。②如(ru)果(guo)(guo)(guo)是(shi)(shi)雙(shuang)動(dong)(dong)(dong)道(dao)(dao)(dao)岔,在(zai)操(cao)動(dong)(dong)(dong)時控制臺(tai)的(de)電(dian)(dian)流表動(dong)(dong)(dong)一下就不(bu)(bu)動(dong)(dong)(dong)了(le),說(shuo)明(ming)動(dong)(dong)(dong)作道(dao)(dao)(dao)岔的(de)電(dian)(dian)已送到了(le)一動(dong)(dong)(dong)道(dao)(dao)(dao)岔,故(gu)障(zhang)出(chu)在(zai)一動(dong)(dong)(dong)道(dao)(dao)(dao)岔以后,是(shi)(shi)室(shi)(shi)(shi)(shi)外故(gu)障(zhang)。③如(ru)果(guo)(guo)(guo)道(dao)(dao)(dao)岔定、反位(wei)都能操(cao)動(dong)(dong)(dong),就是(shi)(shi)沒有(you)表示。用(yong)萬(wan)用(yong)表交流250v檔(dang),在(zai)分線(xian)盤測量X1(或(huo)X2)與X3間有(you)無交流110V左右電(dian)(dian)壓,如(ru)果(guo)(guo)(guo)有(you)電(dian)(dian)壓,則(ze)是(shi)(shi)室(shi)(shi)(shi)(shi)外故(gu)障(zhang),否(fou)則(ze)是(shi)(shi)室(shi)(shi)(shi)(shi)內(nei)故(gu)障(zhang)。
