起動繼電器簡介

起(qi)動繼電器(qi)：保(bao)護線(xian)路，點火開(kai)關。

汽車啟動繼電(dian)器的作用：

1、主要是通過(guo)控(kong)制(zhi)(zhi)低壓(ya)線(xian)路的(de)電(dian)流(liu)來控(kong)制(zhi)(zhi)高壓(ya)線(xian)路的(de)電(dian)流(liu)，起到電(dian)流(liu)開(kai)關的(de)作(zuo)用。啟(qi)動(dong)繼(ji)電(dian)器是啟(qi)動(dong)系統組成部件之一，在汽車上主要作(zuo)用為小(xiao)電(dian)流(liu)；

2、控(kong)制大電(dian)(dian)流方(fang)式(shi)啟動(dong)(dong)馬達轉(zhuan)動(dong)(dong)，從而帶(dai)動(dong)(dong)發電(dian)(dian)機內部磁(ci)電(dian)(dian)機轉(zhuan)子轉(zhuan)動(dong)(dong)，給點(dian)火(huo)器(qi)輸(shu)入(ru)點(dian)火(huo)脈沖信號，使點(dian)火(huo)器(qi)產(chan)生電(dian)(dian)火(huo)花，點(dian)燃(ran)汽(qi)缸內的混合燃(ran)氣(qi)并做功。繼電(dian)(dian)器(qi)屬于開(kai)關類，它是利用電(dian)(dian)磁(ci)原理(li)、機電(dian)(dian)原理(li)使接點(dian)閉(bi)合或斷開(kai)來驅動(dong)(dong)或控(kong)制相關電(dian)(dian)路的；

3、繼電器(qi)為(wei)一種控(kong)(kong)制(zhi)器(qi)件，它有受控(kong)(kong)系(xi)統(tong)（輸(shu)入(ru)回路）和(he)控(kong)(kong)制(zhi)系(xi)統(tong)（輸(shu)出(chu)回路）兩部(bu)分。當輸(shu)入(ru)量（電、磁、光、熱等(deng)物理量）達到(dao)某一定(ding)值(zhi)(zhi)時，輸(shu)出(chu)量躍變(bian)(bian)式(shi)地(di)由(you)零(ling)變(bian)(bian)化(hua)到(dao)一定(ding)值(zhi)(zhi)（或由(you)一定(ding)值(zhi)(zhi)跳變(bian)(bian)到(dao)零(ling)），從而實現對電路的控(kong)(kong)制(zhi)、保護(hu)、調節和(he)傳遞信息等(deng)目(mu)的。

啟(qi)動(dong)繼電(dian)器(qi)(qi)是(shi)單獨部件，其作(zuo)用是(shi)接通、斷(duan)開(kai)吸引線(xian)圈和保持線(xian)圈電(dian)路。在(zai)電(dian)冰(bing)箱、空調器(qi)(qi)這類小型(xing)制冷設備(bei)中，制冷壓縮機多采用單相(xiang)分相(xiang)式異步電(dian)動(dong)機，啟(qi)動(dong)繼電(dian)器(qi)(qi)的作(zuo)用是(shi)幫助(zhu)電(dian)動(dong)機啟(qi)動(dong)，啟(qi)動(dong)完成(cheng)后自動(dong)斷(duan)開(kai)副繞組，避免燒壞副繞組線(xian)圈。
