1.架線式電機車的工作過程
高壓交(jiao)流(liu)(liu)電(dian)(dian)(dian)經牽(qian)引(yin)(yin)變流(liu)(liu)所降壓、整流(liu)(liu)后，正極(ji)接到架空(kong)線上(shang)，負極(ji)接到鐵軌(gui)上(shang)。機車(che)(che)上(shang)的受電(dian)(dian)(dian)弓與架空(kong)線接觸(chu)，將電(dian)(dian)(dian)流(liu)(liu)引(yin)(yin)入車(che)(che)內(nei)，再經空(kong)氣(qi)自(zi)動(dong)(dong)(dong)(dong)開關(guan)、控制器、電(dian)(dian)(dian)阻箱進(jin)入牽(qian)引(yin)(yin)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機，驅動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機運轉。電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機通過傳(chuan)動(dong)(dong)(dong)(dong)裝置帶動(dong)(dong)(dong)(dong)車(che)(che)輪轉動(dong)(dong)(dong)(dong)，從(cong)而牽(qian)引(yin)(yin)列(lie)車(che)(che)行駛。從(cong)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機流(liu)(liu)出的電(dian)(dian)(dian)流(liu)(liu)經軌(gui)道流(liu)(liu)回變流(liu)(liu)所。
2蓄電池(chi)式電機車的(de)工(gong)作(zuo)過程
蓄電(dian)池提供的直流電(dian)經隔爆(bao)插銷(xiao)、控制器、電(dian)阻箱進入電(dian)動(dong)(dong)機(ji)，驅(qu)動(dong)(dong)電(dian)動(dong)(dong)機(ji)運轉。電(dian)動(dong)(dong)機(ji)通過傳動(dong)(dong)裝(zhuang)置帶動(dong)(dong)車輪轉動(dong)(dong)，從而(er)牽引列(lie)車行駛(shi)。
