發電機調節器簡介

汽(qi)車的(de)供(gong)電(dian)(dian)系統(tong)是由汽(qi)車蓄電(dian)(dian)池(chi)和發(fa)電(dian)(dian)機(ji)組(zu)成(cheng)，發(fa)電(dian)(dian)機(ji)負責對(dui)電(dian)(dian)池(chi)進(jin)行(xing)充(chong)電(dian)(dian)，使電(dian)(dian)池(chi)長(chang)期保持在足電(dian)(dian)狀(zhuang)態。電(dian)(dian)池(chi)和發(fa)電(dian)(dian)機(ji)負責對(dui)全車的(de)電(dian)(dian)器進(jin)行(xing)供(gong)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)(dian)機(ji)(ji)(ji)(ji)調節器的(de)(de)主要(yao)作用是為(wei)了控制發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)在(zai)額定(ding)值內(nei)(nei)，由于發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)與發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)的(de)(de)傳動(dong)(dong)(dong)比是固定(ding)的(de)(de)，所以發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)轉速(su)將(jiang)隨發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)轉速(su)的(de)(de)變(bian)化而變(bian)化。汽車在(zai)運行過程(cheng)中發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)轉速(su)變(bian)化范(fan)圍(wei)很大，發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)端電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)也(ye)將(jiang)隨發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)的(de)(de)轉速(su)變(bian)化而在(zai)很大范(fan)圍(wei)內(nei)(nei)變(bian)化。發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)對(dui)用電(dian)(dian)(dian)(dian)(dian)(dian)設備供電(dian)(dian)(dian)(dian)(dian)(dian)和向蓄電(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)，都要(yao)求(qiu)其(qi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)穩定(ding)，為(wei)了使電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)始(shi)終保(bao)持(chi)在(zai)某一數值基本不變(bian)，就必須對(dui)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)進行調節。
