起動繼電器簡介

起(qi)動(dong)繼(ji)電器：保護(hu)線路(lu)，點火開(kai)關(guan)。

汽車啟動繼(ji)電器的作用：

1、主要是通(tong)過控(kong)(kong)制(zhi)低壓線路的(de)電(dian)(dian)流來控(kong)(kong)制(zhi)高壓線路的(de)電(dian)(dian)流，起到電(dian)(dian)流開關(guan)的(de)作(zuo)用。啟動(dong)繼電(dian)(dian)器是啟動(dong)系統組成部件之一，在(zai)汽車(che)上主要作(zuo)用為小(xiao)電(dian)(dian)流；

2、控制(zhi)大電(dian)(dian)流方式啟動(dong)(dong)(dong)馬達轉動(dong)(dong)(dong)，從而(er)帶動(dong)(dong)(dong)發電(dian)(dian)機(ji)內(nei)部磁電(dian)(dian)機(ji)轉子轉動(dong)(dong)(dong)，給點(dian)(dian)(dian)火(huo)器輸入點(dian)(dian)(dian)火(huo)脈沖信號，使點(dian)(dian)(dian)火(huo)器產生電(dian)(dian)火(huo)花，點(dian)(dian)(dian)燃(ran)汽缸內(nei)的(de)混合燃(ran)氣并做功。繼電(dian)(dian)器屬于開關類，它是(shi)利用電(dian)(dian)磁原理(li)(li)、機(ji)電(dian)(dian)原理(li)(li)使接點(dian)(dian)(dian)閉合或(huo)斷開來驅動(dong)(dong)(dong)或(huo)控制(zhi)相關電(dian)(dian)路的(de)；

3、繼電(dian)器為一種控(kong)制(zhi)器件，它有受控(kong)系統(tong)（輸(shu)(shu)入回路(lu)）和控(kong)制(zhi)系統(tong)（輸(shu)(shu)出回路(lu)）兩部(bu)分。當輸(shu)(shu)入量（電(dian)、磁(ci)、光、熱等物理量）達到某一定(ding)值(zhi)時，輸(shu)(shu)出量躍變(bian)式地(di)由零變(bian)化到一定(ding)值(zhi)（或由一定(ding)值(zhi)跳變(bian)到零），從而(er)實現對電(dian)路(lu)的控(kong)制(zhi)、保護(hu)、調節和傳遞信息等目的。

啟動繼(ji)電器是單(dan)獨部件，其(qi)作用是接(jie)通、斷開(kai)吸引線圈和保持線圈電路。在電冰(bing)箱(xiang)、空調器這類小(xiao)型制(zhi)冷設備中(zhong)，制(zhi)冷壓縮機多采用單(dan)相分(fen)相式異步電動機，啟動繼(ji)電器的作用是幫(bang)助電動機啟動，啟動完成后自動斷開(kai)副繞組(zu)，避免燒壞副繞組(zu)線圈。
