發電機調節器簡介

汽(qi)車的供(gong)電(dian)(dian)(dian)(dian)系(xi)統是由汽(qi)車蓄電(dian)(dian)(dian)(dian)池(chi)和發電(dian)(dian)(dian)(dian)機組(zu)成，發電(dian)(dian)(dian)(dian)機負責對電(dian)(dian)(dian)(dian)池(chi)進行(xing)充電(dian)(dian)(dian)(dian)，使電(dian)(dian)(dian)(dian)池(chi)長(chang)期(qi)保持在足電(dian)(dian)(dian)(dian)狀(zhuang)態。電(dian)(dian)(dian)(dian)池(chi)和發電(dian)(dian)(dian)(dian)機負責對全車的電(dian)(dian)(dian)(dian)器進行(xing)供(gong)電(dian)(dian)(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)電(dian)(dian)(dian)機(ji)(ji)調節器的主要作用是(shi)為了控制發(fa)電(dian)(dian)(dian)機(ji)(ji)輸出電(dian)(dian)(dian)壓(ya)(ya)(ya)在額定(ding)值(zhi)內，由于發(fa)電(dian)(dian)(dian)機(ji)(ji)與(yu)發(fa)動(dong)機(ji)(ji)的傳(chuan)動(dong)比是(shi)固定(ding)的，所以發(fa)電(dian)(dian)(dian)機(ji)(ji)的轉(zhuan)速(su)(su)將(jiang)隨發(fa)動(dong)機(ji)(ji)轉(zhuan)速(su)(su)的變(bian)(bian)化而變(bian)(bian)化。汽(qi)車在運行過程(cheng)中發(fa)動(dong)機(ji)(ji)轉(zhuan)速(su)(su)變(bian)(bian)化范圍(wei)很(hen)大，發(fa)電(dian)(dian)(dian)機(ji)(ji)的端電(dian)(dian)(dian)壓(ya)(ya)(ya)也將(jiang)隨發(fa)動(dong)機(ji)(ji)的轉(zhuan)速(su)(su)變(bian)(bian)化而在很(hen)大范圍(wei)內變(bian)(bian)化。發(fa)電(dian)(dian)(dian)機(ji)(ji)對用電(dian)(dian)(dian)設(she)備供電(dian)(dian)(dian)和向蓄電(dian)(dian)(dian)池充電(dian)(dian)(dian)，都要求其電(dian)(dian)(dian)壓(ya)(ya)(ya)穩定(ding)，為了使(shi)電(dian)(dian)(dian)壓(ya)(ya)(ya)始終保持在某(mou)一數(shu)值(zhi)基(ji)本不變(bian)(bian)，就必(bi)須對發(fa)電(dian)(dian)(dian)機(ji)(ji)的輸出電(dian)(dian)(dian)壓(ya)(ya)(ya)進行調節。
