起動繼電器簡介

起動繼(ji)電器：保(bao)護線路，點火開(kai)關。

汽車啟動繼(ji)電器的作用(yong)：

1、主(zhu)要是(shi)通過控制低壓線路的電流來控制高壓線路的電流，起(qi)到電流開關的作用。啟(qi)動繼電器是(shi)啟(qi)動系統組成部件之一，在(zai)汽車(che)上主(zhu)要作用為(wei)小電流；

2、控制(zhi)(zhi)大電(dian)(dian)(dian)(dian)(dian)流(liu)方式啟動(dong)(dong)馬達(da)轉動(dong)(dong)，從而帶動(dong)(dong)發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)內部磁電(dian)(dian)(dian)(dian)(dian)機(ji)轉子轉動(dong)(dong)，給點火器輸(shu)入點火脈沖信(xin)號，使(shi)點火器產生電(dian)(dian)(dian)(dian)(dian)火花(hua)，點燃(ran)汽缸內的(de)混合燃(ran)氣并做(zuo)功。繼電(dian)(dian)(dian)(dian)(dian)器屬于開關類，它是利用電(dian)(dian)(dian)(dian)(dian)磁原(yuan)理、機(ji)電(dian)(dian)(dian)(dian)(dian)原(yuan)理使(shi)接(jie)點閉合或斷開來驅動(dong)(dong)或控制(zhi)(zhi)相關電(dian)(dian)(dian)(dian)(dian)路(lu)的(de)；

3、繼電(dian)器為一(yi)種控(kong)(kong)制(zhi)(zhi)器件，它有(you)受控(kong)(kong)系統（輸入回(hui)路）和控(kong)(kong)制(zhi)(zhi)系統（輸出(chu)回(hui)路）兩部分。當輸入量（電(dian)、磁、光(guang)、熱等物理(li)量）達到某一(yi)定值(zhi)時，輸出(chu)量躍變(bian)(bian)式地由(you)零變(bian)(bian)化到一(yi)定值(zhi)（或由(you)一(yi)定值(zhi)跳變(bian)(bian)到零），從而實現(xian)對電(dian)路的控(kong)(kong)制(zhi)(zhi)、保護、調節和傳遞(di)信(xin)息等目的。

啟動(dong)(dong)(dong)繼電(dian)(dian)器(qi)是(shi)單獨部(bu)件，其作用是(shi)接通、斷開吸引線圈和保持線圈電(dian)(dian)路。在電(dian)(dian)冰箱(xiang)、空(kong)調器(qi)這類(lei)小型制冷(leng)設備中，制冷(leng)壓(ya)縮機(ji)多采用單相分相式異步電(dian)(dian)動(dong)(dong)(dong)機(ji)，啟動(dong)(dong)(dong)繼電(dian)(dian)器(qi)的作用是(shi)幫助電(dian)(dian)動(dong)(dong)(dong)機(ji)啟動(dong)(dong)(dong)，啟動(dong)(dong)(dong)完成(cheng)后(hou)自(zi)動(dong)(dong)(dong)斷開副(fu)繞(rao)組(zu)，避(bi)免燒壞副(fu)繞(rao)組(zu)線圈。

江淮V7簡介

從(cong)江淮汽(qi)車(che)旗下皮卡車(che)型(xing)江淮V7正式上市，官方指導售價為7.18-8.38萬(wan)元(yuan)。新(xin)車(che)共推出八款車(che)型(xing)，動(dong)力方面搭載(zai)了2.0L汽(qi)油和2.0T柴油兩(liang)款發(fa)動(dong)機。
