起動繼電器簡介

起動繼(ji)電(dian)器：保護線路，點火開(kai)關(guan)。

汽車啟(qi)動繼電器的(de)作用(yong)：

1、主要是通(tong)過控制(zhi)(zhi)低壓線路的(de)(de)電(dian)流(liu)(liu)來控制(zhi)(zhi)高壓線路的(de)(de)電(dian)流(liu)(liu)，起到電(dian)流(liu)(liu)開關(guan)的(de)(de)作用。啟動繼電(dian)器是啟動系統(tong)組成部件之一，在汽車上主要作用為小電(dian)流(liu)(liu)；

2、控制(zhi)大電(dian)(dian)(dian)(dian)流方式啟動馬達轉(zhuan)動，從(cong)而帶動發(fa)電(dian)(dian)(dian)(dian)機內(nei)部磁電(dian)(dian)(dian)(dian)機轉(zhuan)子轉(zhuan)動，給點(dian)(dian)火器(qi)輸入點(dian)(dian)火脈沖信號，使點(dian)(dian)火器(qi)產生電(dian)(dian)(dian)(dian)火花(hua)，點(dian)(dian)燃汽缸內(nei)的混合(he)燃氣并做功。繼電(dian)(dian)(dian)(dian)器(qi)屬(shu)于開關類，它是利(li)用(yong)電(dian)(dian)(dian)(dian)磁原(yuan)理、機電(dian)(dian)(dian)(dian)原(yuan)理使接點(dian)(dian)閉(bi)合(he)或斷開來驅動或控制(zhi)相關電(dian)(dian)(dian)(dian)路的；

3、繼電(dian)器(qi)為一種控(kong)制(zhi)器(qi)件，它(ta)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)）兩部分。當輸(shu)(shu)入量(liang)（電(dian)、磁、光、熱等物理(li)量(liang)）達到(dao)某(mou)一定(ding)值(zhi)時，輸(shu)(shu)出量(liang)躍變式地由零變化(hua)到(dao)一定(ding)值(zhi)（或(huo)由一定(ding)值(zhi)跳變到(dao)零），從(cong)而實(shi)現對電(dian)路(lu)的控(kong)制(zhi)、保護、調節和傳遞信息等目的。

啟(qi)動(dong)(dong)(dong)(dong)(dong)繼電(dian)(dian)器(qi)是(shi)單獨部(bu)件(jian)，其(qi)作(zuo)用是(shi)接通、斷開吸引線(xian)圈(quan)和保持線(xian)圈(quan)電(dian)(dian)路。在電(dian)(dian)冰箱、空調(diao)器(qi)這類小型制冷(leng)設備中，制冷(leng)壓縮機多(duo)采用單相分(fen)相式(shi)異(yi)步電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機，啟(qi)動(dong)(dong)(dong)(dong)(dong)繼電(dian)(dian)器(qi)的(de)作(zuo)用是(shi)幫助電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機啟(qi)動(dong)(dong)(dong)(dong)(dong)，啟(qi)動(dong)(dong)(dong)(dong)(dong)完成后自動(dong)(dong)(dong)(dong)(dong)斷開副(fu)繞(rao)(rao)組(zu)，避免燒壞副(fu)繞(rao)(rao)組(zu)線(xian)圈(quan)。
