KPD系(xi)列低壓軌(gui)道(dao)平車(che)是(shi)低壓軌(gui)道(dao)供(gong)(gong)電(dian)(dian)(dian)，先通過(guo)降(jiang)壓變(bian)壓器(qi)將380V動力電(dian)(dian)(dian)壓降(jiang)至(zhi)36V安(an)全電(dian)(dian)(dian)壓，再通過(guo)導電(dian)(dian)(dian)軌(gui)送至(zhi)平車(che)上(shang)，然后通過(guo)升壓變(bian)壓器(qi)升至(zhi)380V交(jiao)(jiao)流(liu)電(dian)(dian)(dian)供(gong)(gong)給(gei)交(jiao)(jiao)流(liu)電(dian)(dian)(dian)機驅(qu)動平車(che)在軌(gui)道(dao)上(shang)行(xing)駛（或通過(guo)整流(liu)器(qi)將36V交(jiao)(jiao)流(liu)電(dian)(dian)(dian)轉換成為48V直流(liu)電(dian)(dian)(dian)供(gong)(gong)給(gei)直流(liu)電(dian)(dian)(dian)機驅(qu)動平車(che)行(xing)駛）；其主要(yao)特(te)點是(shi)不(bu)(bu)用電(dian)(dian)(dian)纜；降(jiang)壓器(qi)以(yi)下是(shi)安(an)全電(dian)(dian)(dian)壓，不(bu)(bu)僅(jin)安(an)全，而(er)且不(bu)(bu)怕燙、不(bu)(bu)怕砸、不(bu)(bu)妨礙交(jiao)(jiao)通運(yun)輸(shu)，容易實現(xian)遙控和自動化；可以(yi)在彎道(dao)、環(huan)道(dao)上(shang)行(xing)駛，適(shi)當(dang)增加(jia)降(jiang)壓器(qi)數量，可以(yi)不(bu)(bu)受平車(che)運(yun)行(xing)距離限制，給(gei)廠區運(yun)輸(shu)帶來很大方便(bian)。
