起動繼電器簡介

起動(dong)繼(ji)電器：保護線路(lu)，點(dian)火開(kai)關。

汽(qi)車啟動繼(ji)電器的作用：

1、主(zhu)(zhu)要(yao)是通過控制低壓線路(lu)的電(dian)(dian)流來(lai)控制高壓線路(lu)的電(dian)(dian)流，起到電(dian)(dian)流開關的作用。啟(qi)動繼電(dian)(dian)器是啟(qi)動系統組成部件之一(yi)，在汽車上(shang)主(zhu)(zhu)要(yao)作用為小電(dian)(dian)流；

2、控制大(da)電(dian)(dian)(dian)流(liu)方(fang)式啟動(dong)(dong)(dong)馬達轉動(dong)(dong)(dong)，從而帶動(dong)(dong)(dong)發電(dian)(dian)(dian)機(ji)內部磁電(dian)(dian)(dian)機(ji)轉子(zi)轉動(dong)(dong)(dong)，給點(dian)火器(qi)(qi)輸入(ru)點(dian)火脈(mo)沖信號(hao)，使(shi)點(dian)火器(qi)(qi)產生電(dian)(dian)(dian)火花(hua)，點(dian)燃汽(qi)缸內的混(hun)合燃氣并做功。繼電(dian)(dian)(dian)器(qi)(qi)屬于開關類(lei)，它(ta)是(shi)利用電(dian)(dian)(dian)磁原理(li)、機(ji)電(dian)(dian)(dian)原理(li)使(shi)接(jie)點(dian)閉(bi)合或斷開來驅動(dong)(dong)(dong)或控制相(xiang)關電(dian)(dian)(dian)路的；

3、繼電(dian)器為一(yi)種控(kong)(kong)制器件，它有受控(kong)(kong)系統（輸入(ru)回路(lu)(lu)）和控(kong)(kong)制系統（輸出(chu)回路(lu)(lu)）兩部分。當輸入(ru)量（電(dian)、磁、光、熱等物理量）達到(dao)(dao)某一(yi)定(ding)值時，輸出(chu)量躍(yue)變(bian)式地由零變(bian)化到(dao)(dao)一(yi)定(ding)值（或(huo)由一(yi)定(ding)值跳變(bian)到(dao)(dao)零），從而實(shi)現對(dui)電(dian)路(lu)(lu)的控(kong)(kong)制、保護、調節和傳遞信息等目的。

啟動(dong)(dong)(dong)(dong)繼電器是(shi)單獨部件，其(qi)作用(yong)是(shi)接通(tong)、斷(duan)開吸引線(xian)圈(quan)和保持線(xian)圈(quan)電路。在電冰箱、空調器這(zhe)類小型制(zhi)(zhi)冷設(she)備(bei)中，制(zhi)(zhi)冷壓(ya)縮機(ji)多采用(yong)單相分相式異步(bu)電動(dong)(dong)(dong)(dong)機(ji)，啟動(dong)(dong)(dong)(dong)繼電器的作用(yong)是(shi)幫(bang)助電動(dong)(dong)(dong)(dong)機(ji)啟動(dong)(dong)(dong)(dong)，啟動(dong)(dong)(dong)(dong)完成(cheng)后自動(dong)(dong)(dong)(dong)斷(duan)開副繞組，避免燒壞副繞組線(xian)圈(quan)。

寶馬Z3簡介

寶(bao)馬Z3是寶(bao)馬系列(lie)的(de)一款車型。1996年(nian)5月，第一批寶(bao)馬問世，很短(duan)時(shi)間(jian)內躍升為同(tong)類中最暢(chang)銷的(de)車型。BMW Z3在2001年(nian)末開始計(ji)劃減產 ，到(dao)2002年(nian)終正(zheng)式停產。
