起動繼電器簡介

起(qi)動(dong)繼電器：保護線路，點(dian)火開關。

汽車(che)啟動繼電器的(de)作用：

1、主要是(shi)通過控制低(di)壓(ya)線(xian)路的(de)電(dian)(dian)(dian)流(liu)(liu)來控制高壓(ya)線(xian)路的(de)電(dian)(dian)(dian)流(liu)(liu)，起到(dao)電(dian)(dian)(dian)流(liu)(liu)開關的(de)作用。啟動(dong)(dong)繼電(dian)(dian)(dian)器是(shi)啟動(dong)(dong)系(xi)統(tong)組成(cheng)部件之一，在汽(qi)車上(shang)主要作用為小電(dian)(dian)(dian)流(liu)(liu)；

2、控(kong)制大電(dian)流方式啟動(dong)(dong)(dong)馬達轉動(dong)(dong)(dong)，從而帶(dai)動(dong)(dong)(dong)發(fa)電(dian)機內部磁(ci)電(dian)機轉子轉動(dong)(dong)(dong)，給(gei)點火(huo)(huo)(huo)器(qi)輸入(ru)點火(huo)(huo)(huo)脈(mo)沖信號，使(shi)點火(huo)(huo)(huo)器(qi)產生電(dian)火(huo)(huo)(huo)花，點燃(ran)汽缸(gang)內的混(hun)合(he)燃(ran)氣并做功。繼(ji)電(dian)器(qi)屬于開(kai)關類，它是利用(yong)電(dian)磁(ci)原理、機電(dian)原理使(shi)接點閉合(he)或斷開(kai)來(lai)驅(qu)動(dong)(dong)(dong)或控(kong)制相關電(dian)路(lu)的；

3、繼電(dian)器為一(yi)(yi)種(zhong)控(kong)制(zhi)器件(jian)，它有受控(kong)系統(tong)（輸入回路(lu)(lu)(lu)）和控(kong)制(zhi)系統(tong)（輸出回路(lu)(lu)(lu)）兩部分。當輸入量（電(dian)、磁、光、熱(re)等物(wu)理(li)量）達到某一(yi)(yi)定值時(shi)，輸出量躍變式地(di)由零變化到一(yi)(yi)定值（或由一(yi)(yi)定值跳變到零），從而實現(xian)對電(dian)路(lu)(lu)(lu)的(de)控(kong)制(zhi)、保護、調節和傳(chuan)遞信息(xi)等目的(de)。

啟動(dong)(dong)(dong)繼電(dian)器是(shi)單獨部件，其作(zuo)用是(shi)接通、斷(duan)開(kai)吸引線(xian)圈和保持(chi)線(xian)圈電(dian)路。在電(dian)冰箱、空調器這類小型制冷設備中，制冷壓縮機(ji)多(duo)采用單相分(fen)相式異步(bu)電(dian)動(dong)(dong)(dong)機(ji)，啟動(dong)(dong)(dong)繼電(dian)器的作(zuo)用是(shi)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(duan)開(kai)副(fu)繞組(zu)，避免燒壞副(fu)繞組(zu)線(xian)圈。
