電壓調節器簡介

電壓調節器電壓調節器的作用：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：

電(dian)(dian)(dian)(dian)壓調節器的工作原理：由于(yu)發(fa)(fa)電(dian)(dian)(dian)(dian)機(ji)與發(fa)(fa)動機(ji)的傳動比(bi)固定(ding)，所(suo)以發(fa)(fa)電(dian)(dian)(dian)(dian)機(ji)的轉(zhuan)速將隨(sui)發(fa)(fa)動機(ji)轉(zhuan)速的變(bian)(bian)化(hua)(hua)而變(bian)(bian)化(hua)(hua)。汽車在(zai)(zai)運(yun)行(xing)過(guo)程中，發(fa)(fa)動機(ji)轉(zhuan)速變(bian)(bian)化(hua)(hua)范(fan)圍很大，發(fa)(fa)電(dian)(dian)(dian)(dian)機(ji)的端電(dian)(dian)(dian)(dian)壓也將隨(sui)發(fa)(fa)動機(ji)的轉(zhuan)速變(bian)(bian)化(hua)(hua)而在(zai)(zai)很大范(fan)圍內(nei)變(bian)(bian)化(hua)(hua)。發(fa)(fa)電(dian)(dian)(dian)(dian)機(ji)對(dui)用(yong)電(dian)(dian)(dian)(dian)設備供電(dian)(dian)(dian)(dian)和向蓄電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)，都要求其電(dian)(dian)(dian)(dian)壓穩定(ding)，所(suo)以為使電(dian)(dian)(dian)(dian)壓始終保(bao)持在(zai)(zai)某一數值(zhi)基本不(bu)變(bian)(bian)，就必須對(dui)發(fa)(fa)電(dian)(dian)(dian)(dian)機(ji)的輸出(chu)電(dian)(dian)(dian)(dian)壓進行(xing)調節。
