起動繼電器簡介

起動(dong)繼電器：保(bao)護線路(lu)，點火開關。

汽車啟動繼電器的作用：

1、主(zhu)要是通(tong)過控制低(di)壓線路(lu)(lu)的電流(liu)(liu)來(lai)控制高壓線路(lu)(lu)的電流(liu)(liu)，起到電流(liu)(liu)開(kai)關的作用。啟動繼電器(qi)是啟動系統(tong)組成部件之(zhi)一，在汽車上(shang)主(zhu)要作用為小電流(liu)(liu)；

2、控(kong)制大電(dian)(dian)(dian)(dian)(dian)流方式啟動馬(ma)達轉動，從而帶動發電(dian)(dian)(dian)(dian)(dian)機內部磁電(dian)(dian)(dian)(dian)(dian)機轉子(zi)轉動，給點(dian)(dian)火器輸(shu)入(ru)點(dian)(dian)火脈沖信(xin)號(hao)，使點(dian)(dian)火器產(chan)生電(dian)(dian)(dian)(dian)(dian)火花，點(dian)(dian)燃汽缸(gang)內的混合燃氣并做功(gong)。繼電(dian)(dian)(dian)(dian)(dian)器屬于開關類，它(ta)是利用電(dian)(dian)(dian)(dian)(dian)磁原理(li)、機電(dian)(dian)(dian)(dian)(dian)原理(li)使接點(dian)(dian)閉合或斷開來驅動或控(kong)制相關電(dian)(dian)(dian)(dian)(dian)路的；

3、繼電器為一(yi)種控(kong)制(zhi)器件，它有受控(kong)系統(tong)（輸入(ru)回路(lu)）和控(kong)制(zhi)系統(tong)（輸出(chu)回路(lu)）兩部(bu)分。當輸入(ru)量(liang)(liang)（電、磁、光、熱(re)等(deng)物理(li)量(liang)(liang)）達到(dao)某一(yi)定(ding)值時，輸出(chu)量(liang)(liang)躍變(bian)(bian)式地由(you)零(ling)變(bian)(bian)化(hua)到(dao)一(yi)定(ding)值（或(huo)由(you)一(yi)定(ding)值跳變(bian)(bian)到(dao)零(ling)），從而(er)實(shi)現(xian)對電路(lu)的(de)控(kong)制(zhi)、保護(hu)、調節和傳遞信息(xi)等(deng)目(mu)的(de)。

啟(qi)動(dong)(dong)(dong)繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)是單獨部(bu)件，其作(zuo)用(yong)是接(jie)通(tong)、斷開吸(xi)引線(xian)(xian)圈和保持線(xian)(xian)圈電(dian)(dian)(dian)(dian)路。在(zai)電(dian)(dian)(dian)(dian)冰箱、空(kong)調器(qi)(qi)這(zhe)類小型制冷設備(bei)中，制冷壓縮機(ji)(ji)多采用(yong)單相分相式異步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)，啟(qi)動(dong)(dong)(dong)繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)的作(zuo)用(yong)是幫助電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)啟(qi)動(dong)(dong)(dong)，啟(qi)動(dong)(dong)(dong)完(wan)成后自動(dong)(dong)(dong)斷開副(fu)繞(rao)組，避免燒壞副(fu)繞(rao)組線(xian)(xian)圈。

天馬乘龍簡介

外觀(guan)威(wei)猛、彪悍，凝聚時代(dai)氣(qi)息(xi)。擁有轎(jiao)(jiao)車的(de)形象，又有載(zai)貨(huo)的(de)實用，享(xiang)受(shou)轎(jiao)(jiao)車的(de)舒適，無論出行，還是載(zai)物，天(tian)馬乘龍都可(ke)勝任，真正滿足(zu)您的(de)生活所需。
我們從科技出(chu)發研究出(chu)更安全和更實用的(de)(de)(de)汽車；從外形出(chu)發，要求汽車的(de)(de)(de)每一(yi)寸空間都不只是各司(si)其職(zhi)那么簡單(dan)，可(ke)以載人(ren)，又可(ke)以載貨，而且還(huan)要再(zai)載更多的(de)(de)(de)貨。一(yi)部天馬(ma)乘龍更可(ke)應付日常的(de)(de)(de)各項需求。
天馬(ma)乘(cheng)龍加(jia)長大(da)雙排，增(zeng)大(da)載貨容量，載貨重心更合(he)理(li)，公告規定載質(zhi)量500千克(ke)，不需增(zeng)加(jia)任何(he)使用費用，使您使用更經濟。
