起動繼電器簡介

起動繼(ji)電器：保(bao)護線(xian)路，點火(huo)開(kai)關。

汽車(che)啟(qi)動繼電(dian)器的(de)作用：

1、主要是通過控制(zhi)低壓線路的(de)(de)電(dian)流(liu)(liu)(liu)來控制(zhi)高壓線路的(de)(de)電(dian)流(liu)(liu)(liu)，起到電(dian)流(liu)(liu)(liu)開關的(de)(de)作用。啟動繼電(dian)器(qi)是啟動系統組成部(bu)件(jian)之(zhi)一(yi)，在汽車上主要作用為小電(dian)流(liu)(liu)(liu)；

2、控(kong)制(zhi)大電(dian)(dian)(dian)(dian)流方式(shi)啟動(dong)馬達轉動(dong)，從而帶動(dong)發電(dian)(dian)(dian)(dian)機(ji)內部磁電(dian)(dian)(dian)(dian)機(ji)轉子轉動(dong)，給點(dian)火(huo)器(qi)輸入點(dian)火(huo)脈沖信號(hao)，使點(dian)火(huo)器(qi)產生電(dian)(dian)(dian)(dian)火(huo)花，點(dian)燃汽缸內的(de)混合燃氣并(bing)做功。繼電(dian)(dian)(dian)(dian)器(qi)屬于開(kai)關(guan)(guan)類(lei)，它是利用(yong)電(dian)(dian)(dian)(dian)磁原理(li)、機(ji)電(dian)(dian)(dian)(dian)原理(li)使接點(dian)閉合或斷(duan)開(kai)來驅動(dong)或控(kong)制(zhi)相關(guan)(guan)電(dian)(dian)(dian)(dian)路(lu)的(de)；

3、繼電(dian)器為一(yi)種控(kong)(kong)制器件，它有受控(kong)(kong)系(xi)統(tong)（輸(shu)(shu)入回路）和(he)控(kong)(kong)制系(xi)統(tong)（輸(shu)(shu)出回路）兩(liang)部分。當輸(shu)(shu)入量(liang)（電(dian)、磁(ci)、光、熱等物理量(liang)）達到某一(yi)定(ding)值時，輸(shu)(shu)出量(liang)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(tiao)變(bian)到零），從而實現對電(dian)路的(de)控(kong)(kong)制、保護、調節和(he)傳遞信息等目(mu)的(de)。

啟(qi)(qi)(qi)動(dong)(dong)繼電(dian)器是單獨部件，其作用是接通、斷(duan)開(kai)吸引線(xian)圈(quan)(quan)和保(bao)持線(xian)圈(quan)(quan)電(dian)路(lu)。在(zai)電(dian)冰箱、空調器這類小型制冷設備中(zhong)，制冷壓縮機多(duo)采(cai)用單相(xiang)(xiang)分相(xiang)(xiang)式異步電(dian)動(dong)(dong)機，啟(qi)(qi)(qi)動(dong)(dong)繼電(dian)器的作用是幫助電(dian)動(dong)(dong)機啟(qi)(qi)(qi)動(dong)(dong)，啟(qi)(qi)(qi)動(dong)(dong)完成后(hou)自動(dong)(dong)斷(duan)開(kai)副繞組，避(bi)免燒壞副繞組線(xian)圈(quan)(quan)。

一汽佳寶簡介

2011年3月4日，歷經(jing)四大晉(jin)級(ji)、六大增配、五(wu)十五(wu)項品(pin)質(zhi)優化后，一汽(qi)吉(ji)林(lin)汽(qi)車(che)有限公司2011款佳寶V70將在長春、濟南、鄭州同時上市。此舉表明：中國(guo)一汽(qi)的微車(che)計劃已出重拳，微客硬漢的威(wei)猛升級(ji)，無疑增加了一汽(qi)吉(ji)林(lin)的制勝籌碼。
