起動繼電器簡介

起動繼電器：保護(hu)線路(lu)，點火開關(guan)。

汽(qi)車啟(qi)動繼電器的(de)作用：

1、主要是(shi)通(tong)過(guo)控(kong)制(zhi)低壓(ya)線路(lu)的(de)電流(liu)來(lai)控(kong)制(zhi)高壓(ya)線路(lu)的(de)電流(liu)，起(qi)到電流(liu)開(kai)關的(de)作用。啟動(dong)繼電器是(shi)啟動(dong)系統組成部件之一，在汽車上(shang)主要作用為小(xiao)電流(liu)；

2、控(kong)(kong)制大(da)電(dian)(dian)(dian)流方式啟(qi)動(dong)馬達轉(zhuan)動(dong)，從而帶動(dong)發電(dian)(dian)(dian)機(ji)(ji)內部磁電(dian)(dian)(dian)機(ji)(ji)轉(zhuan)子轉(zhuan)動(dong)，給(gei)點(dian)(dian)(dian)火(huo)器輸入點(dian)(dian)(dian)火(huo)脈沖(chong)信號，使(shi)點(dian)(dian)(dian)火(huo)器產生電(dian)(dian)(dian)火(huo)花，點(dian)(dian)(dian)燃(ran)汽缸內的混合燃(ran)氣并做功。繼電(dian)(dian)(dian)器屬(shu)于開(kai)關(guan)類(lei)，它(ta)是利用電(dian)(dian)(dian)磁原理、機(ji)(ji)電(dian)(dian)(dian)原理使(shi)接(jie)點(dian)(dian)(dian)閉合或(huo)斷開(kai)來驅(qu)動(dong)或(huo)控(kong)(kong)制相關(guan)電(dian)(dian)(dian)路的；

3、繼電器為一(yi)種控(kong)制器件，它有(you)受控(kong)系統（輸(shu)(shu)入(ru)回路(lu)）和(he)控(kong)制系統（輸(shu)(shu)出回路(lu)）兩部分。當輸(shu)(shu)入(ru)量（電、磁(ci)、光(guang)、熱等物理量）達到(dao)某一(yi)定值(zhi)時(shi)，輸(shu)(shu)出量躍變(bian)式地(di)由(you)零變(bian)化到(dao)一(yi)定值(zhi)（或由(you)一(yi)定值(zhi)跳變(bian)到(dao)零），從而實現對電路(lu)的控(kong)制、保護、調(diao)節和(he)傳(chuan)遞信(xin)息等目(mu)的。

啟動繼電(dian)器(qi)是(shi)單(dan)獨(du)部件(jian)，其作(zuo)用是(shi)接(jie)通、斷(duan)開吸引線(xian)(xian)圈和保持線(xian)(xian)圈電(dian)路。在電(dian)冰(bing)箱、空調器(qi)這類小(xiao)型(xing)制冷設備(bei)中，制冷壓縮(suo)機多采用單(dan)相分相式異步(bu)電(dian)動機，啟動繼電(dian)器(qi)的作(zuo)用是(shi)幫(bang)助電(dian)動機啟動，啟動完成后自動斷(duan)開副(fu)(fu)繞組，避免燒(shao)壞副(fu)(fu)繞組線(xian)(xian)圈。

樂風簡介

雪(xue)佛蘭樂風(feng)LOVA，是一款為中國(guo)(guo)消費(fei)者打造的小(xiao)(xiao)車，要(yao)為中國(guo)(guo)的道(dao)路而生(sheng)(sheng)(sheng)，為中國(guo)(guo)的消費(fei)者而生(sheng)(sheng)(sheng)，如其(qi)(qi)命名一樣，正是要(yao)印(yin)證(zheng)“知本一族”對生(sheng)(sheng)(sheng)活(huo)的熱(re)愛(ai)、對自我的堅持，和對明天的渴望，他們需要(yao)的是一款具有國(guo)(guo)際品(pin)(pin)牌保證(zheng)的、既(ji)實用(yong)又(you)能提高生(sheng)(sheng)(sheng)活(huo)品(pin)(pin)質的經(jing)濟型小(xiao)(xiao)車。LOVA雖然是一款小(xiao)(xiao)排量的小(xiao)(xiao)型車，卻融匯了(le)諸(zhu)多高檔(dang)三(san)廂(xiang)轎車的設計精(jing)髓，樂風(feng)以大(da)(da)設計、大(da)(da)空(kong)間、大(da)(da)動力和大(da)(da)品(pin)(pin)牌實現了(le)時(shi)尚和實用(yong)的完(wan)美結合，使其(qi)(qi)真(zhen)正成為精(jing)品(pin)(pin)家(jia)轎的典范。
