起動繼電器簡介

起(qi)動繼(ji)電器：保(bao)護線路，點火(huo)開關。

汽車啟動繼(ji)電器的作用：

1、主(zhu)(zhu)要是通(tong)過控制低(di)壓(ya)(ya)線路的電(dian)流來控制高壓(ya)(ya)線路的電(dian)流，起到電(dian)流開關(guan)的作(zuo)用。啟動繼電(dian)器(qi)是啟動系統(tong)組成部件之一，在汽(qi)車上主(zhu)(zhu)要作(zuo)用為(wei)小電(dian)流；

2、控(kong)制(zhi)大電(dian)(dian)流方式啟(qi)動馬達轉(zhuan)動，從而帶動發電(dian)(dian)機(ji)內部磁電(dian)(dian)機(ji)轉(zhuan)子轉(zhuan)動，給點(dian)(dian)火(huo)器輸入點(dian)(dian)火(huo)脈沖信號(hao)，使點(dian)(dian)火(huo)器產生電(dian)(dian)火(huo)花，點(dian)(dian)燃(ran)汽缸內的混合(he)燃(ran)氣并做(zuo)功。繼電(dian)(dian)器屬于開關類，它是利(li)用電(dian)(dian)磁原(yuan)理、機(ji)電(dian)(dian)原(yuan)理使接點(dian)(dian)閉合(he)或(huo)(huo)斷開來驅動或(huo)(huo)控(kong)制(zhi)相關電(dian)(dian)路的；

3、繼(ji)電器為一(yi)種控制器件，它有受控系(xi)統(tong)（輸入(ru)回路(lu)）和控制系(xi)統(tong)（輸出回路(lu)）兩部分。當輸入(ru)量(liang)（電、磁、光(guang)、熱等物理(li)量(liang)）達到某一(yi)定(ding)值時，輸出量(liang)躍變(bian)(bian)式地由零變(bian)(bian)化到一(yi)定(ding)值（或由一(yi)定(ding)值跳(tiao)變(bian)(bian)到零），從而實(shi)現對電路(lu)的控制、保(bao)護、調(diao)節(jie)和傳遞信息等目的。

啟(qi)動(dong)繼電(dian)(dian)器(qi)是單獨部件，其作(zuo)用(yong)是接通、斷開吸引線圈和保持線圈電(dian)(dian)路。在電(dian)(dian)冰(bing)箱、空調器(qi)這類小型制冷設(she)備中，制冷壓縮機(ji)多采用(yong)單相(xiang)(xiang)分相(xiang)(xiang)式異步電(dian)(dian)動(dong)機(ji)，啟(qi)動(dong)繼電(dian)(dian)器(qi)的作(zuo)用(yong)是幫助電(dian)(dian)動(dong)機(ji)啟(qi)動(dong)，啟(qi)動(dong)完成后自動(dong)斷開副繞組，避免燒(shao)壞副繞組線圈。
