起動繼電器簡介

起動繼電器(qi)：保護(hu)線路，點(dian)火開關。

汽車啟動繼電器的作用(yong)：

1、主要是通過控(kong)制(zhi)低(di)壓線路的(de)電(dian)流(liu)來(lai)控(kong)制(zhi)高壓線路的(de)電(dian)流(liu)，起到電(dian)流(liu)開關(guan)的(de)作(zuo)用。啟動繼電(dian)器是啟動系統(tong)組成部件之一，在汽車上主要作(zuo)用為小電(dian)流(liu)；

2、控制(zhi)大電(dian)(dian)流方式(shi)啟動(dong)(dong)(dong)馬達轉動(dong)(dong)(dong)，從(cong)而帶動(dong)(dong)(dong)發電(dian)(dian)機內(nei)部磁(ci)電(dian)(dian)機轉子轉動(dong)(dong)(dong)，給(gei)點(dian)火(huo)器(qi)輸入點(dian)火(huo)脈沖信號，使(shi)點(dian)火(huo)器(qi)產生電(dian)(dian)火(huo)花，點(dian)燃汽(qi)缸內(nei)的(de)混合(he)(he)燃氣并做功。繼(ji)電(dian)(dian)器(qi)屬于(yu)開關類，它(ta)是利用電(dian)(dian)磁(ci)原理(li)、機電(dian)(dian)原理(li)使(shi)接點(dian)閉合(he)(he)或(huo)斷開來驅動(dong)(dong)(dong)或(huo)控制(zhi)相關電(dian)(dian)路的(de)；

3、繼電器(qi)(qi)為一(yi)種控(kong)(kong)制器(qi)(qi)件，它(ta)有受(shou)控(kong)(kong)系(xi)統（輸(shu)入(ru)(ru)回路）和(he)控(kong)(kong)制系(xi)統（輸(shu)出回路）兩部(bu)分。當輸(shu)入(ru)(ru)量（電、磁、光、熱等(deng)(deng)物理量）達到某(mou)一(yi)定(ding)值時，輸(shu)出量躍變(bian)式地(di)由(you)零變(bian)化到一(yi)定(ding)值（或由(you)一(yi)定(ding)值跳變(bian)到零），從而實現對電路的控(kong)(kong)制、保護、調節和(he)傳遞信息等(deng)(deng)目的。

啟動(dong)(dong)(dong)繼電(dian)(dian)器(qi)(qi)是(shi)(shi)單(dan)獨(du)部件(jian)，其作用是(shi)(shi)接通、斷開(kai)吸引線(xian)圈和保持線(xian)圈電(dian)(dian)路。在電(dian)(dian)冰箱(xiang)、空調器(qi)(qi)這類小型制(zhi)冷(leng)設(she)備中，制(zhi)冷(leng)壓縮機(ji)多采用單(dan)相分(fen)相式異步電(dian)(dian)動(dong)(dong)(dong)機(ji)，啟動(dong)(dong)(dong)繼電(dian)(dian)器(qi)(qi)的作用是(shi)(shi)幫(bang)助電(dian)(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)斷開(kai)副繞(rao)組(zu)，避(bi)免燒壞(huai)副繞(rao)組(zu)線(xian)圈。

風景(進口)簡介

雷諾(nuo)(nuo)風景是(shi)雷諾(nuo)(nuo)Megane系列車中的單廂(xiang)車型，它開創(chuang)了單廂(xiang)車的新概念。該車型創(chuang)新的設(she)計(ji)、寬敞的空(kong)間(jian)(jian)、多功能性和獨特的風格，裝(zhuang)備靈巧機智為人(ren)稱道。儀表板設(she)計(ji)的簡潔而實用，能顯示行車距離(li)、油量、平均油耗、瞬間(jian)(jian)油耗等有(you)用信息。
