起動繼電器簡介

起(qi)動繼電器：保護線(xian)路，點火開關。

汽車(che)啟動繼電器的作用(yong)：

1、主要是通過控制低壓線路的電(dian)(dian)(dian)流(liu)來(lai)控制高壓線路的電(dian)(dian)(dian)流(liu)，起到電(dian)(dian)(dian)流(liu)開關的作(zuo)用。啟動繼電(dian)(dian)(dian)器是啟動系統(tong)組成部件之一，在(zai)汽車上主要作(zuo)用為(wei)小電(dian)(dian)(dian)流(liu)；

2、控制(zhi)大電(dian)流方式(shi)啟動馬達轉動，從而帶動發電(dian)機內部磁電(dian)機轉子轉動，給點(dian)火(huo)(huo)器輸(shu)入點(dian)火(huo)(huo)脈(mo)沖信號，使點(dian)火(huo)(huo)器產生(sheng)電(dian)火(huo)(huo)花，點(dian)燃汽(qi)缸(gang)內的混合燃氣(qi)并做功。繼(ji)電(dian)器屬于開關(guan)(guan)類，它是利用電(dian)磁原理(li)、機電(dian)原理(li)使接點(dian)閉合或(huo)斷開來驅動或(huo)控制(zhi)相關(guan)(guan)電(dian)路的；

3、繼電(dian)器(qi)為一(yi)種控(kong)制(zhi)(zhi)器(qi)件(jian)，它(ta)有受控(kong)系(xi)統(tong)（輸入(ru)回(hui)(hui)路(lu)）和控(kong)制(zhi)(zhi)系(xi)統(tong)（輸出回(hui)(hui)路(lu)）兩(liang)部(bu)分。當輸入(ru)量（電(dian)、磁、光、熱等物(wu)理量）達到某一(yi)定(ding)值時，輸出量躍(yue)變式地由零變化到一(yi)定(ding)值（或由一(yi)定(ding)值跳變到零），從而實現對電(dian)路(lu)的控(kong)制(zhi)(zhi)、保護、調節和傳遞信(xin)息等目的。

啟動(dong)繼電(dian)(dian)器是(shi)單獨部件，其作(zuo)用(yong)(yong)(yong)是(shi)接通(tong)、斷(duan)(duan)開吸引線(xian)(xian)圈(quan)和保(bao)持(chi)線(xian)(xian)圈(quan)電(dian)(dian)路。在(zai)電(dian)(dian)冰(bing)箱、空調(diao)器這類(lei)小型制冷設備中，制冷壓縮機(ji)多采用(yong)(yong)(yong)單相分相式異(yi)步電(dian)(dian)動(dong)機(ji)，啟動(dong)繼電(dian)(dian)器的作(zuo)用(yong)(yong)(yong)是(shi)幫助電(dian)(dian)動(dong)機(ji)啟動(dong)，啟動(dong)完成后自(zi)動(dong)斷(duan)(duan)開副繞組，避免(mian)燒(shao)壞副繞組線(xian)(xian)圈(quan)。
