起動繼電器簡介

起動繼(ji)電器：保護線路，點火開(kai)關。

汽車啟動繼電器(qi)的作(zuo)用：

1、主(zhu)要是(shi)通(tong)過控制(zhi)低壓線路(lu)的(de)電流來控制(zhi)高壓線路(lu)的(de)電流，起到電流開關(guan)的(de)作用。啟(qi)(qi)動(dong)繼電器是(shi)啟(qi)(qi)動(dong)系(xi)統組成部件之(zhi)一(yi)，在(zai)汽(qi)車上主(zhu)要作用為小電流；

2、控制大電(dian)(dian)(dian)流方式啟動馬達轉動，從而帶動發電(dian)(dian)(dian)機(ji)內部磁電(dian)(dian)(dian)機(ji)轉子轉動，給(gei)點(dian)(dian)火(huo)器(qi)(qi)輸入點(dian)(dian)火(huo)脈沖信(xin)號，使點(dian)(dian)火(huo)器(qi)(qi)產生電(dian)(dian)(dian)火(huo)花，點(dian)(dian)燃汽(qi)缸內的混(hun)合(he)燃氣(qi)并(bing)做功。繼電(dian)(dian)(dian)器(qi)(qi)屬于開(kai)關類，它是利(li)用電(dian)(dian)(dian)磁原(yuan)(yuan)理(li)、機(ji)電(dian)(dian)(dian)原(yuan)(yuan)理(li)使接(jie)點(dian)(dian)閉合(he)或(huo)斷(duan)開(kai)來驅動或(huo)控制相關電(dian)(dian)(dian)路的；

3、繼電(dian)器為一(yi)(yi)(yi)種(zhong)控制(zhi)(zhi)器件，它有受控系統（輸(shu)入(ru)回路(lu)）和控制(zhi)(zhi)系統（輸(shu)出(chu)回路(lu)）兩部分(fen)。當輸(shu)入(ru)量(liang)（電(dian)、磁、光、熱等物理量(liang)）達到某一(yi)(yi)(yi)定(ding)(ding)值(zhi)時(shi)，輸(shu)出(chu)量(liang)躍(yue)變式地由(you)零(ling)變化到一(yi)(yi)(yi)定(ding)(ding)值(zhi)（或(huo)由(you)一(yi)(yi)(yi)定(ding)(ding)值(zhi)跳變到零(ling)），從而實(shi)現對電(dian)路(lu)的(de)控制(zhi)(zhi)、保護、調節(jie)和傳遞信息等目的(de)。

啟(qi)(qi)動(dong)繼(ji)(ji)電(dian)(dian)器是(shi)單(dan)(dan)獨部件，其作用是(shi)接通、斷(duan)開吸引線(xian)圈和保持線(xian)圈電(dian)(dian)路。在電(dian)(dian)冰箱、空調器這類(lei)小型制冷(leng)設(she)備中，制冷(leng)壓縮機多采用單(dan)(dan)相(xiang)分相(xiang)式異步電(dian)(dian)動(dong)機，啟(qi)(qi)動(dong)繼(ji)(ji)電(dian)(dian)器的作用是(shi)幫(bang)助電(dian)(dian)動(dong)機啟(qi)(qi)動(dong)，啟(qi)(qi)動(dong)完成后自動(dong)斷(duan)開副(fu)繞組(zu)，避免燒(shao)壞副(fu)繞組(zu)線(xian)圈。

啟辰e30晨風簡介

“晨風”是(shi)東風日(ri)(ri)(ri)產啟(qi)辰品牌(pai)首(shou)款量產純(chun)電動(dong)(dong)車，自廣(guang)州(zhou)車展首(shou)次亮(liang)相(xiang)以來，一直是(shi)備受行(xing)(xing)業(ye)和市場關注(zhu)。啟(qi)辰晨風代表著當前全球純(chun)電動(dong)(dong)車的(de)(de)領(ling)先技術(shu)水平(ping)，性能可靠，其核心技術(shu)日(ri)(ri)(ri)臻(zhen)完善，海外已久經考驗。在(zai)國內，東風日(ri)(ri)(ri)產與(yu)武漢、廣(guang)州(zhou)、大連(lian)等城市聯合開展的(de)(de)示(shi)范運營項目已經累計無故(gu)障行(xing)(xing)駛超過(guo)百萬公里。
