起動繼電器簡介

起動繼(ji)電器：保(bao)護線(xian)路，點火(huo)開關。

汽車(che)啟動繼電(dian)器的(de)作(zuo)用：

1、主(zhu)要是通過控制低壓線路的電(dian)流(liu)(liu)來控制高壓線路的電(dian)流(liu)(liu)，起到電(dian)流(liu)(liu)開關的作(zuo)用。啟動繼電(dian)器是啟動系統組成(cheng)部件之(zhi)一，在汽車(che)上主(zhu)要作(zuo)用為小(xiao)電(dian)流(liu)(liu)；

2、控(kong)制(zhi)大(da)電(dian)(dian)流方式啟動(dong)(dong)馬(ma)達轉(zhuan)動(dong)(dong)，從(cong)而帶動(dong)(dong)發電(dian)(dian)機內部(bu)磁電(dian)(dian)機轉(zhuan)子(zi)轉(zhuan)動(dong)(dong)，給點(dian)(dian)火器輸(shu)入點(dian)(dian)火脈沖信(xin)號，使點(dian)(dian)火器產生電(dian)(dian)火花(hua)，點(dian)(dian)燃(ran)汽缸內的混(hun)合燃(ran)氣并(bing)做功。繼電(dian)(dian)器屬于(yu)開(kai)關類(lei)，它是利(li)用電(dian)(dian)磁原(yuan)理、機電(dian)(dian)原(yuan)理使接(jie)點(dian)(dian)閉合或斷開(kai)來驅動(dong)(dong)或控(kong)制(zhi)相關電(dian)(dian)路的；

3、繼電器為一種控制(zhi)器件，它(ta)有受控系統（輸入回(hui)路）和控制(zhi)系統（輸出(chu)回(hui)路）兩部分(fen)。當輸入量(liang)（電、磁(ci)、光、熱等(deng)物理(li)量(liang)）達到某一定值時，輸出(chu)量(liang)躍變(bian)式地由(you)零變(bian)化到一定值（或由(you)一定值跳變(bian)到零），從而實現對電路的控制(zhi)、保護、調(diao)節和傳遞信(xin)息等(deng)目的。

啟動(dong)(dong)繼電(dian)(dian)(dian)(dian)器(qi)是單(dan)獨(du)部件，其作(zuo)用(yong)是接(jie)通、斷開(kai)吸(xi)引線(xian)圈和保(bao)持線(xian)圈電(dian)(dian)(dian)(dian)路。在(zai)電(dian)(dian)(dian)(dian)冰箱、空調器(qi)這類小(xiao)型制(zhi)冷設備中，制(zhi)冷壓縮機多采(cai)用(yong)單(dan)相(xiang)分相(xiang)式異步電(dian)(dian)(dian)(dian)動(dong)(dong)機，啟動(dong)(dong)繼電(dian)(dian)(dian)(dian)器(qi)的作(zuo)用(yong)是幫(bang)助電(dian)(dian)(dian)(dian)動(dong)(dong)機啟動(dong)(dong)，啟動(dong)(dong)完成后(hou)自(zi)動(dong)(dong)斷開(kai)副(fu)繞(rao)組，避(bi)免燒壞副(fu)繞(rao)組線(xian)圈。
