起動繼電器簡介

起(qi)動繼電器(qi)：保護線路，點火開關(guan)。

汽車(che)啟動繼電(dian)器的作用：

1、主要是(shi)通過控(kong)制(zhi)低壓(ya)線(xian)路的電流來控(kong)制(zhi)高壓(ya)線(xian)路的電流，起到電流開關的作用。啟動繼電器是(shi)啟動系統組成(cheng)部件之一，在汽(qi)車上(shang)主要作用為小(xiao)電流；

2、控制(zhi)大(da)電(dian)(dian)(dian)(dian)流(liu)方式啟動(dong)馬達轉動(dong)，從而(er)帶(dai)動(dong)發電(dian)(dian)(dian)(dian)機內部磁電(dian)(dian)(dian)(dian)機轉子轉動(dong)，給點(dian)火器輸入點(dian)火脈沖(chong)信號，使(shi)點(dian)火器產生電(dian)(dian)(dian)(dian)火花，點(dian)燃(ran)汽(qi)缸(gang)內的(de)混合(he)燃(ran)氣(qi)并做功。繼電(dian)(dian)(dian)(dian)器屬(shu)于開關(guan)類，它是利用(yong)電(dian)(dian)(dian)(dian)磁原(yuan)理(li)、機電(dian)(dian)(dian)(dian)原(yuan)理(li)使(shi)接點(dian)閉合(he)或斷開來驅動(dong)或控制(zhi)相關(guan)電(dian)(dian)(dian)(dian)路的(de)；

3、繼電器為(wei)一(yi)(yi)種控(kong)制器件，它(ta)有受(shou)控(kong)系統(tong)（輸(shu)入(ru)回路(lu)）和控(kong)制系統(tong)（輸(shu)出回路(lu)）兩部分(fen)。當(dang)輸(shu)入(ru)量(liang)（電、磁、光(guang)、熱等(deng)物理量(liang)）達到某一(yi)(yi)定(ding)值時，輸(shu)出量(liang)躍變(bian)式地由(you)零變(bian)化到一(yi)(yi)定(ding)值（或由(you)一(yi)(yi)定(ding)值跳變(bian)到零），從(cong)而(er)實現(xian)對電路(lu)的控(kong)制、保護、調節和傳遞(di)信息等(deng)目的。

啟動(dong)(dong)(dong)繼電(dian)器是單(dan)獨部件，其作用是接通(tong)、斷開(kai)吸(xi)引線圈和保持線圈電(dian)路(lu)。在電(dian)冰箱、空調器這類小型制冷(leng)設備中(zhong)，制冷(leng)壓縮機(ji)多(duo)采用單(dan)相(xiang)分相(xiang)式異步電(dian)動(dong)(dong)(dong)機(ji)，啟動(dong)(dong)(dong)繼電(dian)器的作用是幫助電(dian)動(dong)(dong)(dong)機(ji)啟動(dong)(dong)(dong)，啟動(dong)(dong)(dong)完成后自動(dong)(dong)(dong)斷開(kai)副(fu)繞(rao)組(zu)，避免(mian)燒壞副(fu)繞(rao)組(zu)線圈。
