起動繼電器簡介

起動(dong)繼電(dian)器：保(bao)護(hu)線路，點火開關。

汽車啟動繼電器的作用：

1、主要是通過控制(zhi)低(di)壓線(xian)路的(de)電(dian)流來(lai)控制(zhi)高壓線(xian)路的(de)電(dian)流，起到電(dian)流開關的(de)作用。啟動繼電(dian)器是啟動系統組成(cheng)部件之(zhi)一(yi)，在(zai)汽車上(shang)主要作用為小電(dian)流；

2、控(kong)制大電(dian)(dian)(dian)(dian)流方式(shi)啟動(dong)(dong)(dong)馬達轉(zhuan)動(dong)(dong)(dong)，從而帶動(dong)(dong)(dong)發電(dian)(dian)(dian)(dian)機內部磁(ci)電(dian)(dian)(dian)(dian)機轉(zhuan)子(zi)轉(zhuan)動(dong)(dong)(dong)，給點火器(qi)輸入點火脈沖(chong)信號，使點火器(qi)產(chan)生電(dian)(dian)(dian)(dian)火花，點燃(ran)汽缸內的(de)混合燃(ran)氣(qi)并做(zuo)功。繼電(dian)(dian)(dian)(dian)器(qi)屬于開關(guan)類，它是(shi)利(li)用電(dian)(dian)(dian)(dian)磁(ci)原理、機電(dian)(dian)(dian)(dian)原理使接點閉合或(huo)斷開來驅動(dong)(dong)(dong)或(huo)控(kong)制相(xiang)關(guan)電(dian)(dian)(dian)(dian)路的(de)；

3、繼電(dian)器為(wei)一(yi)種控(kong)制(zhi)器件(jian)，它有受控(kong)系統（輸(shu)入回路）和控(kong)制(zhi)系統（輸(shu)出回路）兩部分(fen)。當(dang)輸(shu)入量（電(dian)、磁、光(guang)、熱(re)等物理(li)量）達到某(mou)一(yi)定值時，輸(shu)出量躍變式(shi)地(di)由零(ling)變化到一(yi)定值（或由一(yi)定值跳變到零(ling)），從而實現對電(dian)路的控(kong)制(zhi)、保護、調節和傳遞信息等目的。

啟動(dong)繼電(dian)器是(shi)單獨部件，其(qi)作用是(shi)接通(tong)、斷開(kai)吸(xi)引線(xian)圈(quan)和保(bao)持(chi)線(xian)圈(quan)電(dian)路。在電(dian)冰箱(xiang)、空調器這類(lei)小型制冷設備中，制冷壓縮機多采(cai)用單相分相式異步(bu)電(dian)動(dong)機，啟動(dong)繼電(dian)器的作用是(shi)幫助電(dian)動(dong)機啟動(dong)，啟動(dong)完(wan)成后自動(dong)斷開(kai)副(fu)繞(rao)組，避免燒壞副(fu)繞(rao)組線(xian)圈(quan)。

速派(進口)簡介

從前(qian)面(mian)看，車子的鍥形大燈與直豎格柵依然(ran)沿用斯柯(ke)達傳統的硬朗造(zao)型，有歐雅的影子。繞到(dao)側面(mian)，車頂由大幅(fu)傾斜的a柱(zhu)延(yan)伸到(dao)弧線狀(zhuang)的c柱(zhu)，前(qian)面(mian)保險杠低垂(chui)，后面(mian)車尾線條(tiao)簡潔，完全是現代(dai)轎車的流行風(feng)格。
