起動繼電器簡介

起動繼電器：保護線路，點火(huo)開關(guan)。

汽(qi)車啟動繼(ji)電器的(de)作用：

1、主要是通過控制低壓線路的(de)電(dian)流(liu)來控制高壓線路的(de)電(dian)流(liu)，起(qi)到電(dian)流(liu)開關(guan)的(de)作用(yong)。啟(qi)動繼(ji)電(dian)器(qi)是啟(qi)動系統組成部件之一(yi)，在(zai)汽車(che)上主要作用(yong)為小電(dian)流(liu)；

2、控制(zhi)(zhi)大電(dian)(dian)(dian)流方式啟動(dong)(dong)馬達轉(zhuan)動(dong)(dong)，從而帶(dai)動(dong)(dong)發電(dian)(dian)(dian)機內部(bu)磁(ci)電(dian)(dian)(dian)機轉(zhuan)子轉(zhuan)動(dong)(dong)，給點(dian)火器輸(shu)入點(dian)火脈沖信號(hao)，使(shi)點(dian)火器產(chan)生(sheng)電(dian)(dian)(dian)火花，點(dian)燃(ran)汽缸(gang)內的混(hun)合燃(ran)氣并做功(gong)。繼(ji)電(dian)(dian)(dian)器屬于(yu)開(kai)關類，它是利用電(dian)(dian)(dian)磁(ci)原(yuan)理、機電(dian)(dian)(dian)原(yuan)理使(shi)接點(dian)閉合或(huo)斷(duan)開(kai)來驅動(dong)(dong)或(huo)控制(zhi)(zhi)相關電(dian)(dian)(dian)路的；

3、繼電器為一(yi)種(zhong)控(kong)制器件，它有受(shou)控(kong)系統(tong)（輸(shu)入回路）和控(kong)制系統(tong)（輸(shu)出(chu)回路）兩部分。當輸(shu)入量(liang)(liang)（電、磁、光、熱等物理量(liang)(liang)）達到(dao)某(mou)一(yi)定(ding)值時(shi)，輸(shu)出(chu)量(liang)(liang)躍(yue)變(bian)式地(di)由(you)零變(bian)化到(dao)一(yi)定(ding)值（或由(you)一(yi)定(ding)值跳變(bian)到(dao)零），從而實(shi)現(xian)對電路的(de)控(kong)制、保護、調節和傳遞信息等目的(de)。

啟(qi)(qi)動(dong)(dong)(dong)繼電(dian)器是(shi)(shi)單獨部(bu)件(jian)，其(qi)作用是(shi)(shi)接通、斷開(kai)吸引線(xian)圈(quan)和保持線(xian)圈(quan)電(dian)路。在電(dian)冰箱、空調器這類小型制(zhi)冷設備中，制(zhi)冷壓縮機(ji)多采用單相(xiang)分相(xiang)式異步(bu)電(dian)動(dong)(dong)(dong)機(ji)，啟(qi)(qi)動(dong)(dong)(dong)繼電(dian)器的作用是(shi)(shi)幫助電(dian)動(dong)(dong)(dong)機(ji)啟(qi)(qi)動(dong)(dong)(dong)，啟(qi)(qi)動(dong)(dong)(dong)完成后自動(dong)(dong)(dong)斷開(kai)副(fu)繞(rao)組，避免燒壞副(fu)繞(rao)組線(xian)圈(quan)。

比亞迪G3簡介

比(bi)(bi)亞迪(di)G3與豐田卡羅拉相似的內飾風格，搭載了(le)自行研發的無鑰匙系統，主動開(kai)閉(bi)車門，發動機一鍵啟(qi)動等(deng)。比(bi)(bi)亞迪(di)G3是比(bi)(bi)亞迪(di)全新(xin)的高端車網絡A3的首款產品，也(ye)是G系車型的第(di)一款，G3的上市標志著比(bi)(bi)亞迪(di)開(kai)始向高端化(hua)邁進(jin)(jin)G3的前臉酷似卡羅拉，晶(jing)鉆式透鏡前大(da)燈顯得動感十(shi)足(zu)，大(da)尺寸兩(liang)段式鍍鉻進(jin)(jin)氣(qi)格柵，兩(liang)邊的棱角微(wei)微(wei)上揚，優雅中(zhong)平添一絲霸氣(qi)。
