轉彎電動平車無電源顯示

　　轉彎電動平車無電源顯示

　　1、不通電(dian)(dian)：電(dian)(dian)系統是否對電(dian)(dian)動平車(che)電(dian)(dian)源送(song)電(dian)(dian)，一(yi)般用試電(dian)(dian)筆測試，如沒送(song)電(dian)(dian)，等(deng)送(song)電(dian)(dian)后再工作。

　　2、缺(que)相(xiang)(xiang)：驅(qu)動(dong)(dong)電(dian)(dian)機主、控回(hui)路(lu)的(de)電(dian)(dian)器(qi)損壞、線(xian)(xian)路(lu)斷(duan)開或(huo)接觸不良，也會使平(ping)(ping)車(che)驅(qu)動(dong)(dong)電(dian)(dian)機缺(que)相(xiang)(xiang)無法正常工作(zuo)，出現這種情況(kuang)，需檢修主、控回(hui)路(lu)，檢修時，為了防止主、控回(hui)路(lu)送給三相(xiang)(xiang)電(dian)(dian)機的(de)電(dian)(dian)源(yuan)缺(que)相(xiang)(xiang)而(er)燒毀(hui)電(dian)(dian)機，或(huo)電(dian)(dian)動(dong)(dong)平(ping)(ping)車(che)驅(qu)動(dong)(dong)電(dian)(dian)機突然得電(dian)(dian)運(yun)轉，產生危害，要先將(jiang)電(dian)(dian)機從電(dian)(dian)源(yuan)線(xian)(xian)路(lu)上斷(duan)開，只給主、控回(hui)路(lu)送電(dian)(dian)，然后點動(dong)(dong)起(qi)動(dong)(dong)和停止開關(guan)，檢查分析控制電(dian)(dian)器(qi)及線(xian)(xian)路(lu)的(de)工作(zuo)情況(kuang)，對(dui)有(you)問題的(de)電(dian)(dian)器(qi)或(huo)線(xian)(xian)路(lu)進行修復或(huo)更換，當確(que)認主、控回(hui)路(lu)無故障，方可重新(xin)試車(che)。

　　3、電(dian)(dian)(dian)(dian)(dian)壓過(guo)低(di)：電(dian)(dian)(dian)(dian)(dian)機(ji)端電(dian)(dian)(dian)(dian)(dian)壓比額定電(dian)(dian)(dian)(dian)(dian)壓低(di)10%以(yi)上，電(dian)(dian)(dian)(dian)(dian)機(ji)起動轉矩過(guo)小，使電(dian)(dian)(dian)(dian)(dian)動平車無(wu)法運動，而無(wu)法工具(ju)作(zuo)，檢查時，用萬用表或電(dian)(dian)(dian)(dian)(dian)壓表等測量(liang)電(dian)(dian)(dian)(dian)(dian)機(ji)輸入端電(dian)(dian)(dian)(dian)(dian)壓。
