汽車現(xian)在已(yi)經普及,未(wei)來可能會(hui)每人都有(you)一輛屬(shu)于自己的(de)車子(zi),有(you)了車子(zi)就該知(zhi)(zhi)道在汽車中的(de)一些(xie)基(ji)本的(de)知(zhi)(zhi)識(shi),你知(zhi)(zhi)道車載發電機的(de)類型都有(you)那些(xie)嗎(ma)?讓(rang)我(wo)們來了解一下吧。
汽(qi)車用發電(dian)(dian)機(ji)可分(fen)為兩種,分(fen)別是(shi)(shi)直(zhi)(zhi)流發電(dian)(dian)機(ji)和(he)交(jiao)(jiao)流發電(dian)(dian)機(ji),直(zhi)(zhi)流發電(dian)(dian)機(ji)有兩種:一種是(shi)(shi)電(dian)(dian)機(ji)本(ben)體是(shi)(shi)交(jiao)(jiao)流的(de),通過(guo)電(dian)(dian)子整(zheng)流而變(bian)成(cheng)(cheng)直(zhi)(zhi)流發電(dian)(dian)機(ji);另一種是(shi)(shi)使用換向器把交(jiao)(jiao)流電(dian)(dian)變(bian)成(cheng)(cheng)直(zhi)(zhi)流輸出(chu)的(de)。直(zhi)(zhi)流發電(dian)(dian)機(ji)的(de)弱點就是(shi)(shi)有電(dian)(dian)流的(de)換向問題,消(xiao)耗有色金屬較多,成(cheng)(cheng)本(ben)高(gao),運(yun)行(xing)中的(de)維護檢(jian)修也比較麻煩(fan)。
交流發電(dian)(dian)機是(shi)(shi)根據電(dian)(dian)磁(ci)感應原理(li)制作(zuo)的(de),就(jiu)(jiu)是(shi)(shi)說,不管是(shi)(shi)導體(ti)(線(xian)(xian)圈(quan))運動(dong),還是(shi)(shi)磁(ci)場(chang)運動(dong),只要(yao)導體(ti)(線(xian)(xian)圈(quan))與磁(ci)場(chang)之間(jian)有相對運動(dong),導體(ti)(線(xian)(xian)圈(quan))切割磁(ci)力線(xian)(xian),就(jiu)(jiu)會(hui)在導體(ti)(線(xian)(xian)圈(quan))中產生電(dian)(dian)動(dong)勢,即動(dong)了才(cai)有電(dian)(dian)才(cai)叫發電(dian)(dian)。交流發電(dian)(dian)機由汽車發動(dong)機驅動(dong),是(shi)(shi)汽車電(dian)(dian)氣的(de)主(zhu)要(yao)電(dian)(dian)源,它在正常工作(zuo)時,對除啟動(dong)機以(yi)(yi)外的(de)所有用電(dian)(dian)設(she)備(bei)供(gong)電(dian)(dian),并(bing)向(xiang)蓄電(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)以(yi)(yi)補(bu)充(chong)蓄電(dian)(dian)池(chi)(chi)在使用中消耗的(de)電(dian)(dian)能。
雖然直(zhi)流發電(dian)機(ji)和直(zhi)流電(dian)動機(ji)的(de)用(yong)途各不同,它們的(de)結(jie)構基本上一樣,都是利用(yong)電(dian)和磁的(de)相互作(zuo)用(yong)來實(shi)現機(ji)械能(neng)與電(dian)能(neng)的(de)相互轉換。現在你們知道車載發電(dian)機(ji)的(de)類型了嗎。
