發電機調節器簡介

汽車的供電(dian)(dian)系統是由汽車蓄(xu)電(dian)(dian)池(chi)(chi)和發電(dian)(dian)機(ji)(ji)組成，發電(dian)(dian)機(ji)(ji)負責對電(dian)(dian)池(chi)(chi)進(jin)行充(chong)電(dian)(dian)，使電(dian)(dian)池(chi)(chi)長期保持在足(zu)電(dian)(dian)狀態(tai)。電(dian)(dian)池(chi)(chi)和發電(dian)(dian)機(ji)(ji)負責對全車的電(dian)(dian)器進(jin)行供電(dian)(dian)。

電壓調節器的作用：在發電機轉速變化時，自動控制發電機電壓，使其保持恒定，防止發電機電壓過高而燒壞用電設備和導致蓄電池過量充電，同時也防止發電機電壓過低而導致用電設備工作失常和蓄電池充電不足。
電壓調節器的工作原理：由于發電機與發動機的傳動比固定，所以發電機的轉速將隨發動機轉速的變化而變化。汽車在運行過程中，發動機轉速變化范圍很大，發電機的端電壓也將隨發動機的轉速變化而在很大范圍內變化。發電機對用電設備供電和向蓄電池充電，都要求其電壓穩定，所以為使電壓始終保持在某一數值基本不變，就必須對發電機的輸出電壓進行調節。

發電機調節器的主要作用

發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)調節器的(de)(de)主要作用是為了控制(zhi)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)在額定(ding)值(zhi)內(nei)，由于發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)與發(fa)(fa)動機(ji)(ji)的(de)(de)傳動比(bi)是固定(ding)的(de)(de)，所以(yi)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)轉速(su)將隨(sui)發(fa)(fa)動機(ji)(ji)轉速(su)的(de)(de)變化(hua)而變化(hua)。汽(qi)車在運行(xing)過程中發(fa)(fa)動機(ji)(ji)轉速(su)變化(hua)范(fan)圍(wei)(wei)很大(da)，發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)端(duan)電(dian)(dian)(dian)(dian)(dian)壓(ya)也(ye)將隨(sui)發(fa)(fa)動機(ji)(ji)的(de)(de)轉速(su)變化(hua)而在很大(da)范(fan)圍(wei)(wei)內(nei)變化(hua)。發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)對用電(dian)(dian)(dian)(dian)(dian)設(she)備(bei)供電(dian)(dian)(dian)(dian)(dian)和向蓄電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)，都要求其電(dian)(dian)(dian)(dian)(dian)壓(ya)穩定(ding)，為了使電(dian)(dian)(dian)(dian)(dian)壓(ya)始終保持在某(mou)一數值(zhi)基本不變，就(jiu)必(bi)須對發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)進行(xing)調節。
