起動繼電器簡介

起動繼(ji)電(dian)器：保(bao)護線路，點(dian)火(huo)開關(guan)。

汽(qi)車啟動繼(ji)電器的(de)作用：

1、主要是通過(guo)控(kong)制低壓線路的電(dian)流(liu)(liu)來控(kong)制高壓線路的電(dian)流(liu)(liu)，起到電(dian)流(liu)(liu)開關的作用(yong)。啟動繼電(dian)器是啟動系統組成(cheng)部件(jian)之一，在(zai)汽車上主要作用(yong)為小電(dian)流(liu)(liu)；

2、控制大電(dian)(dian)流方式啟動(dong)(dong)(dong)馬達轉(zhuan)動(dong)(dong)(dong)，從而帶動(dong)(dong)(dong)發電(dian)(dian)機(ji)內(nei)部磁電(dian)(dian)機(ji)轉(zhuan)子轉(zhuan)動(dong)(dong)(dong)，給點火(huo)(huo)器(qi)(qi)輸入點火(huo)(huo)脈(mo)沖信(xin)號，使(shi)點火(huo)(huo)器(qi)(qi)產生(sheng)電(dian)(dian)火(huo)(huo)花，點燃(ran)汽缸內(nei)的混(hun)合(he)燃(ran)氣并做功。繼電(dian)(dian)器(qi)(qi)屬于開關類，它是利用電(dian)(dian)磁原理、機(ji)電(dian)(dian)原理使(shi)接點閉合(he)或(huo)斷開來驅動(dong)(dong)(dong)或(huo)控制相關電(dian)(dian)路(lu)的；

3、繼(ji)電(dian)(dian)器為一(yi)(yi)種控(kong)制(zhi)器件，它有受控(kong)系(xi)統（輸入(ru)回(hui)路(lu)）和控(kong)制(zhi)系(xi)統（輸出回(hui)路(lu)）兩部分。當輸入(ru)量（電(dian)(dian)、磁、光(guang)、熱等物理量）達到(dao)某一(yi)(yi)定(ding)值時，輸出量躍變(bian)式地(di)由零變(bian)化到(dao)一(yi)(yi)定(ding)值（或由一(yi)(yi)定(ding)值跳變(bian)到(dao)零），從而實現對電(dian)(dian)路(lu)的控(kong)制(zhi)、保護(hu)、調節和傳遞信息等目(mu)的。

啟(qi)動(dong)(dong)繼電(dian)(dian)(dian)器(qi)是(shi)單獨部(bu)件(jian)，其作用(yong)是(shi)接通、斷開吸引線圈和保持線圈電(dian)(dian)(dian)路。在(zai)電(dian)(dian)(dian)冰箱、空調器(qi)這類小(xiao)型(xing)制冷設備中，制冷壓縮(suo)機(ji)(ji)多采用(yong)單相分相式異步電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)，啟(qi)動(dong)(dong)繼電(dian)(dian)(dian)器(qi)的作用(yong)是(shi)幫助電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)啟(qi)動(dong)(dong)，啟(qi)動(dong)(dong)完成(cheng)后自動(dong)(dong)斷開副(fu)繞組，避免燒壞(huai)副(fu)繞組線圈。

上汽大眾輝昂新能源簡介

大眾輝(hui)昂在車(che)身整體(ti)設(she)計(ji)上(shang)(shang)沿用了此前(qian)(qian)CCoupe概(gai)念車(che)的設(she)計(ji)思路，大眾家(jia)族(zu)式的車(che)頭設(she)計(ji)，前(qian)(qian)格柵與(yu)LED前(qian)(qian)大燈(deng)融為一(yi)體(ti)，并且(qie)向車(che)身側面延伸(shen)。側面腰(yao)線貫穿整個車(che)身，并且(qie)延伸(shen)至尾燈(deng)上(shang)(shang)方。另外尾燈(deng)設(she)計(ji)也極具看點，輝(hui)昂的尾燈(deng)采用雙(shuang)層設(she)計(ji)，下層尾燈(deng)向內收縮，形成錯落感(gan)
