湖南架線式電機車工作原理是怎樣的呢？南(nan)方電機車小編跟大家一起了(le)解一下：

 架(jia)(jia)線(xian)(xian)(xian)式電(dian)(dian)(dian)(dian)(dian)機(ji)車(che)是(shi)借受(shou)電(dian)(dian)(dian)(dian)(dian)弓(gong)從電(dian)(dian)(dian)(dian)(dian)路上取得電(dian)(dian)(dian)(dian)(dian)能的(de)(de)。當電(dian)(dian)(dian)(dian)(dian)機(ji)車(che)運(yun)行時，受(shou)電(dian)(dian)(dian)(dian)(dian)弓(gong)沿著架(jia)(jia)空線(xian)(xian)(xian)滑動(dong)。架(jia)(jia)線(xian)(xian)(xian)式電(dian)(dian)(dian)(dian)(dian)機(ji)車(che)的(de)(de)供(gong)電(dian)(dian)(dian)(dian)(dian)方(fang)式是(shi)，由中央變(bian)電(dian)(dian)(dian)(dian)(dian)所引來(lai)的(de)(de)高壓電(dian)(dian)(dian)(dian)(dian)纜，供(gong)給(gei)牽(qian)(qian)引變(bian)流所三相(xiang)(xiang)交流電(dian)(dian)(dian)(dian)(dian)源(yuan)，經變(bian)壓器(qi)降壓，再(zai)經低壓電(dian)(dian)(dian)(dian)(dian)纜送到(dao)變(bian)流設(she)備，將交流電(dian)(dian)(dian)(dian)(dian)變(bian)為(wei)直流。直流電(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)正極(ji)通過供(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)纜與架(jia)(jia)空線(xian)(xian)(xian)導線(xian)(xian)(xian)相(xiang)(xiang)連接(jie)(jie)，期間的(de)(de)接(jie)(jie)點(dian)(dian)(dian)成(cheng)為(wei)供(gong)電(dian)(dian)(dian)(dian)(dian)點(dian)(dian)(dian)，其負極(ji)通過回電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)纜與軌(gui)(gui)(gui)道連接(jie)(jie)，相(xiang)(xiang)應的(de)(de)接(jie)(jie)點(dian)(dian)(dian)稱(cheng)為(wei)回電(dian)(dian)(dian)(dian)(dian)點(dian)(dian)(dian)。工(gong)作時，沿軌(gui)(gui)(gui)道運(yun)行的(de)(de)電(dian)(dian)(dian)(dian)(dian)機(ji)車(che)上部，靠受(shou)電(dian)(dian)(dian)(dian)(dian)弓(gong)接(jie)(jie)觸架(jia)(jia)空線(xian)(xian)(xian)獲取電(dian)(dian)(dian)(dian)(dian)能，下部則利用車(che)輪與軌(gui)(gui)(gui)道接(jie)(jie)觸，構成(cheng)一(yi)個回路，使(shi)牽(qian)(qian)引電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)工(gong)作，從而使(shi)電(dian)(dian)(dian)(dian)(dian)機(ji)車(che)牽(qian)(qian)引礦(kuang)車(che)行駛。

 由此可見，架線式電機車的(de)(de)運(yun)行軌(gui)道，同時又是電(dian)(dian)流回路(lu)的(de)(de)導(dao)線(xian)。為了減(jian)(jian)少牽引電(dian)(dian)網的(de)(de)電(dian)(dian)壓降，一(yi)般在(zai)鋼(gang)軌(gui)的(de)(de)接縫處利用導(dao)線(xian)或銅片連接，以減(jian)(jian)少接縫處的(de)(de)電(dian)(dian)阻。
