起動繼電器簡介

起動繼(ji)電器：保護線路，點火(huo)開(kai)關。

汽車啟動繼電(dian)器的(de)作用：

1、主要(yao)是通過(guo)控制低壓(ya)線路的(de)電(dian)流(liu)來控制高壓(ya)線路的(de)電(dian)流(liu)，起(qi)到電(dian)流(liu)開關的(de)作(zuo)用(yong)。啟(qi)動繼(ji)電(dian)器是啟(qi)動系統組成部件之(zhi)一，在汽車(che)上主要(yao)作(zuo)用(yong)為小電(dian)流(liu)；

2、控制(zhi)大電(dian)(dian)流方(fang)式(shi)啟動(dong)馬達轉(zhuan)動(dong)，從而(er)帶動(dong)發電(dian)(dian)機內部磁電(dian)(dian)機轉(zhuan)子轉(zhuan)動(dong)，給(gei)點(dian)火(huo)(huo)器(qi)(qi)輸入點(dian)火(huo)(huo)脈沖(chong)信號，使點(dian)火(huo)(huo)器(qi)(qi)產生電(dian)(dian)火(huo)(huo)花，點(dian)燃汽缸內的(de)混合(he)燃氣并做功。繼電(dian)(dian)器(qi)(qi)屬于(yu)開關類，它是利用電(dian)(dian)磁原(yuan)理(li)、機電(dian)(dian)原(yuan)理(li)使接點(dian)閉合(he)或(huo)斷開來驅動(dong)或(huo)控制(zhi)相關電(dian)(dian)路的(de)；

3、繼(ji)電(dian)(dian)器為一(yi)種控(kong)制器件，它(ta)有受(shou)控(kong)系(xi)統(tong)（輸(shu)(shu)入回(hui)(hui)路）和(he)控(kong)制系(xi)統(tong)（輸(shu)(shu)出回(hui)(hui)路）兩部(bu)分。當(dang)輸(shu)(shu)入量（電(dian)(dian)、磁、光、熱等物(wu)理量）達到(dao)某一(yi)定值時，輸(shu)(shu)出量躍變(bian)式地(di)由零變(bian)化(hua)到(dao)一(yi)定值（或由一(yi)定值跳變(bian)到(dao)零），從(cong)而實(shi)現對電(dian)(dian)路的(de)控(kong)制、保(bao)護、調節(jie)和(he)傳(chuan)遞(di)信息等目的(de)。

啟動(dong)(dong)繼(ji)電(dian)器是(shi)單獨部(bu)件，其作(zuo)用(yong)是(shi)接通(tong)、斷(duan)開吸引線圈(quan)(quan)和保持(chi)線圈(quan)(quan)電(dian)路。在電(dian)冰(bing)箱、空(kong)調(diao)器這類小型制冷(leng)設備中，制冷(leng)壓(ya)縮機多采用(yong)單相分相式異(yi)步電(dian)動(dong)(dong)機，啟動(dong)(dong)繼(ji)電(dian)器的作(zuo)用(yong)是(shi)幫助電(dian)動(dong)(dong)機啟動(dong)(dong)，啟動(dong)(dong)完成(cheng)后自動(dong)(dong)斷(duan)開副繞(rao)組(zu)，避免燒壞(huai)副繞(rao)組(zu)線圈(quan)(quan)。
