工(gong)控(kong)機電(dian)源(yuan)開(kai)關(guan)輸(shu)出直(zhi)流電(dian)壓(ya)過(guo)低造(zao)成(cheng)的(de)故(gu)障(zhang)

故(gu)障(zhang)現象：工(gong)控(kong)機電(dian)源(yuan)開(kai)關(guan)有直(zhi)流電(dian)壓(ya)輸(shu)出，但(dan)輸(shu)出直(zhi)流電(dian)壓(ya)過(guo)低

故(gu)障(zhang)分(fen)析：對(dui)於這種故(gu)障(zhang)現象，根據維修(xiu)經(jing)驗可知，除(chu)穩(wen)壓(ya)控(kong)制(zhi)電(dian)路會(hui)引起輸(shu)出電(dian)壓(ya)過(guo)低外(wai)，還有壹(yi)些(xie)原(yuan)因會引起輸(shu)出電(dian)壓(ya)過(guo)低，主(zhu)要有以下幾點(dian):

1.開(kai)關(guan)電(dian)源(yuan)負(fu)載有短路(lu)故(gu)障(zhang)。此(ci)時(shi)，應斷開(kai)開(kai)關(guan)電(dian)源(yuan)電(dian)路的(de)所(suo)有負載，以區分是開(kai)關(guan)電(dian)源(yuan)電(dian)路還(hai)是負(fu)載電(dian)路有故(gu)障(zhang)。若斷開(kai)負(fu)載電(dian)路電(dian)壓(ya)輸(shu)出正常，說(shuo)明是負載過(guo)重(zhong)；若仍不正常，說(shuo)明開(kai)關(guan)電(dian)源(yuan)電(dian)路有故(gu)障(zhang)。

維(wei)修方法：對(dui)於工(gong)控(kong)機電(dian)源(yuan)這種故(gu)障(zhang)我(wo)們可以根據以上(shang)故(gu)障(zhang)原(yuan)因，來(lai)逐壹(yi)進行(xing)排查(zha)。但(dan)在(zai)實際維(wei)修時(shi)，可(ke)根據實際情(qing)況來(lai)進行(xing)排查(zha)，不(bu)壹(yi)定要逐壹(yi)排查(zha)。首(shou)先(xian)用(yong)萬(wan)用表(biao)檢(jian)查(zha)壹(yi)下高壓(ya)直(zhi)流濾(lv)波(bo)電(dian)容是(shi)否變質，容量(liang)是(shi)否下降，能否正常充(chong)放電(dian)。
