二、牽引電動機詳細介紹：


       在電(dian)(dian)(dian)力(li)機(ji)(ji)車(che)或(huo)動(dong)(dong)(dong)(dong)車(che)里用(yong)以驅(qu)動(dong)(dong)(dong)(dong)器(qi)一根或(huo)幾顆(ke)動(dong)(dong)(dong)(dong)輪(lun)(lun)軸的(de)(de)(de)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)。牽(qian)引電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)有(you)各種類型，如直流(liu)(liu)(liu)(liu)牽(qian)引電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)、溝通(tong)交流(liu)(liu)(liu)(liu)多線程牽(qian)引電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)和(he)溝通(tong)交流(liu)(liu)(liu)(liu)同歩(bu)牽(qian)引電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)等(deng)。直流(liu)(liu)(liu)(liu)牽(qian)引電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)，特(te)(te)(te)(te)別(bie)是(shi)在是(shi)直流(liu)(liu)(liu)(liu)串(chuan)勵電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)有(you)不錯變(bian)速特(te)(te)(te)(te)性(xing)與(yu)工作特(te)(te)(te)(te)點(dian)，融入電(dian)(dian)(dian)力(li)機(ji)(ji)車(che)牽(qian)引特(te)(te)(te)(te)點(dian)的(de)(de)(de)必須(xu)，得到(dao)市(shi)場應用(yong)。　牽(qian)引電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)原理與(yu)一般直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)機(ji)(ji)同樣，但是(shi)獨特(te)(te)(te)(te)的(de)(de)(de)工作中標準：室內空間規(gui)格遭受護(hu)軌和(he)主動(dong)(dong)(dong)(dong)輪(lun)(lun)直經(jing)的(de)(de)(de)限(xian)定；在電(dian)(dian)(dian)力(li)機(ji)(ji)車(che)運作根據(ju)軌縫和(he)道岔時要(yao)承擔非常(chang)大(da)的(de)(de)(de)沖(chong)擊(ji)(ji)性(xing)震(zhen)動(dong)(dong)(dong)(dong)；大(da)、傳動(dong)(dong)(dong)(dong)齒(chi)輪(lun)(lun)齒(chi)合欠佳時電(dian)(dian)(dian)樞上面造(zao)成明顯的(de)(de)(de)扭曲震(zhen)動(dong)(dong)(dong)(dong);在極端自(zi)然環境(jing)中應用(yong)，雨、雪(xue)、灰沙非常(chang)容(rong)易入侵等(deng)。因而牽(qian)引電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)在設計方案和(he)構(gou)造(zao)上也(ye)是(shi)很多規(gui)定，若想靈活運用(yong)人體(ti)室內空間使結構(gou)緊湊，要(yao)選用(yong)高(gao)級(ji)的(de)(de)(de)絕緣(yuan)層材料和(he)導磁原材料，零部(bu)件須(xu)要(yao)較(jiao)(jiao)高(gao)的(de)(de)(de)沖(chong)擊(ji)(ji)韌性(xing)和(he)彎(wan)曲剛度，整臺電(dian)(dian)(dian)機(ji)(ji)須(xu)要(yao)優(you)良的(de)(de)(de)自(zi)然通(tong)風熱管散熱標準和(he)防污防濕工作能(neng)力(li)，要(yao)采用(yong)獨特(te)(te)(te)(te)的(de)(de)(de)對(dui)策以應對(dui)較(jiao)(jiao)為艱難的(de)(de)(de)“換相”標準以降(jiang)低炭刷下(xia)的(de)(de)(de)火苗等(deng)。
 

 

三、牽引發電(dian)機詳細介紹：


       1、專用(yong)型于電(dian)(dian)(dian)(dian)力工程傳動系統(tong)內燃(ran)機(ji)(ji)(ji)(ji)車，以供(gong)求平(ping)衡牽(qian)(qian)(qian)引(yin)(yin)電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)力工程的(de)(de)(de)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)，稱為主發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)。牽(qian)(qian)(qian)引(yin)(yin)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)有直(zhi)(zhi)流(liu)(liu)(liu)和溝(gou)通(tong)交(jiao)流(liu)(liu)(liu)二種。直(zhi)(zhi)流(liu)(liu)(liu)牽(qian)(qian)(qian)引(yin)(yin)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)立即向直(zhi)(zhi)流(liu)(liu)(liu)牽(qian)(qian)(qian)引(yin)(yin)電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)供(gong)電(dian)(dian)(dian)(dian)系統(tong)。溝(gou)通(tong)交(jiao)流(liu)(liu)(liu)牽(qian)(qian)(qian)引(yin)(yin)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)傳出的(de)(de)(de)三相交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)經硅整(zheng)流(liu)(liu)(liu)器(qi)變(bian)壓(ya)(ya)器(qi)后再向直(zhi)(zhi)流(liu)(liu)(liu)牽(qian)(qian)(qian)引(yin)(yin)電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)供(gong)電(dian)(dian)(dian)(dian)系統(tong)。溝(gou)通(tong)交(jiao)流(liu)(liu)(liu)逆變(bian)電(dian)(dian)(dian)(dian)路是三相的(de)(de)(de)，變(bian)壓(ya)(ya)器(qi)工作電(dian)(dian)(dian)(dian)壓(ya)(ya)盡(jin)管有脈(mo)動，但脈(mo)動量較為小，因而牽(qian)(qian)(qian)引(yin)(yin)電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)還被(bei)覺得是一(yi)般的(de)(de)(de)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)；

 ;      2、輔助(zhu)工(gong)(gong)具(ju)電(dian)機(ji)(ji)：電(dian)力機(ji)(ji)車上(shang)的輔助(zhu)工(gong)(gong)具(ju)電(dian)機(ji)(ji)能(neng)用(yong)直流(liu)電(dian)機(ji)(ji)，也能(neng)用(yong)三相溝(gou)通交(jiao)流(liu)異步(bu)電(dian)機(ji)(ji)。用(yong)直流(liu)電(dian)機(ji)(ji)做(zuo)為輔助(zhu)工(gong)(gong)具(ju)電(dian)機(ji)(ji)時，須(xu)由(you)專用(yong)型的硅整流(liu)器供(gong)(gong)電(dian)系統。用(yong)三相溝(gou)通交(jiao)流(liu)多線程輔助(zhu)工(gong)(gong)具(ju)電(dian)動(dong)(dong)機(ji)(ji)時，須(xu)由(you)靜止不動(dong)(dong)變著(zhu)法子、直流(liu)變頻設備或專用(yong)型的轉(zhuan)動(dong)(dong)電(dian)機(ji)(ji)供(gong)(gong)求平衡(heng)三相電(dian)源。這類專用(yong)型的轉(zhuan)動(dong)(dong)電(dian)機(ji)(ji)稱之為劈相機(ji)(ji)，能(neng)夠把單相交(jiao)流(liu)電(dian)變成三相交(jiao)流(liu)電(dian)。
 

 

四、電力機具牽引機有兩種懸掛方法：


      1、一種是牽(qian)引(yin)電(dian)動(dong)機(ji)(ji)和(he)動(dong)輪(lun)軸聯(lian)(lian)接的懸(xuan)(xuan)掛(gua)方法(fa)，稱之(zhi)為(wei)抱軸式(shi)(shi)懸(xuan)(xuan)掛(gua)或(huo)(huo)半懸(xuan)(xuan)掛(gua)。選(xuan)用(yong)這類(lei)懸(xuan)(xuan)掛(gua)方法(fa)時(shi)(shi)，主(zhu)動(dong)輪(lun)根據軌縫和(he)道岔所造(zao)成的沖(chong)擊性震動(dong)會立即發送給牽(qian)引(yin)電(dian)動(dong)機(ji)(ji)。抱軸式(shi)(shi)懸(xuan)(xuan)掛(gua)適用(yong)構(gou)(gou)造(zao)速(su)率小(xiao)于(yu)120千米/鐘(zhong)(zhong)頭的機(ji)(ji)車車輛。另一種是架(jia)承式(shi)(shi)懸(xuan)(xuan)掛(gua)(或(huo)(huo)稱全懸(xuan)(xuan)掛(gua))。選(xuan)用(yong)這類(lei)懸(xuan)(xuan)掛(gua)方法(fa)時(shi)(shi)牽(qian)引(yin)電(dian)動(dong)機(ji)(ji)固定(ding)不動(dong)懸(xuan)(xuan)掛(gua)在(zai)轉(zhuan)向(xiang)架(jia)架(jia)構(gou)(gou)上，在(zai)牽(qian)引(yin)電(dian)機(ji)(ji)轉(zhuan)軸端和(he)小(xiao)、大齒輪(lun)中間添加各種各樣(yang)延展性聯(lian)(lian)接元器件，以減少沖(chong)擊性震動(dong)的危害。架(jia)承式(shi)(shi)懸(xuan)(xuan)掛(gua)適用(yong)構(gou)(gou)造(zao)速(su)率高(gao)過(guo)120千米/鐘(zhong)(zhong)頭的機(ji)(ji)車車輛；
 
      2、在用牽(qian)引變電(dian)器(qi)降血壓(ya)經硅整流(liu)器(qi)或大功率晶閘管變壓(ya)器(qi)后供電(dian)系(xi)統給直流(liu)串勵牽(qian)引電(dian)動(dong)機(ji)時(shi)，加進牽(qian)引電(dian)動(dong)機(ji)里(li)的(de)工(gong)作(zuo)電(dian)壓(ya)為脈(mo)動(dong)工(gong)作(zuo)電(dian)壓(ya)，因而(er)(er)這(zhe)類牽(qian)引電(dian)動(dong)機(ji)稱(cheng)之(zhi)為脈(mo)流(liu)牽(qian)引電(dian)動(dong)機(ji)。功率脈(mo)流(liu)牽(qian)引電(dian)動(dong)機(ji)的(de)“換相”標準更為艱(jian)難(nan)。除此之(zhi)外，電(dian)動(dong)機(ji)內部也有一些額外耗損，進而(er)(er)造(zao)成電(dian)動(dong)機(ji)溫度，因而(er)(er)，脈(mo)流(liu)牽(qian)引電(dian)動(dong)機(ji)在設計方案和構造(zao)上(shang)也要采用一定的(de)獨特對策，以處理“換相”和溫度2個凸(tu)出的(de)難(nan)題。
