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)(dian)壓(ya)(ya)調(diao)節(jie)器的(de)工作(zuo)原理(li)：由于發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)與發(fa)(fa)(fa)(fa)動(dong)機(ji)(ji)的(de)傳動(dong)比(bi)固定(ding)，所以(yi)發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)轉(zhuan)速(su)(su)將(jiang)隨發(fa)(fa)(fa)(fa)動(dong)機(ji)(ji)轉(zhuan)速(su)(su)的(de)變(bian)化(hua)而變(bian)化(hua)。汽車在運行(xing)過程中，發(fa)(fa)(fa)(fa)動(dong)機(ji)(ji)轉(zhuan)速(su)(su)變(bian)化(hua)范(fan)圍很大，發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)端(duan)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)也(ye)將(jiang)隨發(fa)(fa)(fa)(fa)動(dong)機(ji)(ji)的(de)轉(zhuan)速(su)(su)變(bian)化(hua)而在很大范(fan)圍內變(bian)化(hua)。發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)對用電(dian)(dian)(dian)(dian)(dian)設備供電(dian)(dian)(dian)(dian)(dian)和(he)向蓄(xu)電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)，都要求(qiu)其電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)穩定(ding)，所以(yi)為使電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)始終保(bao)持在某一數值基本不變(bian)，就必須對發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)進行(xing)調(diao)節(jie)。

SAVANA商務之星簡介

savana是gmc品牌(pai)中的(de)商(shang)用車系列。gmc除了savana（商務之星）外，還有有使節（envoy）、峽谷（canyon）、西拉（sierra）育空河（yukon）、旅行（safari）等一系列車型。
savana自從1965年首次面世以來只經歷過一次徹底的重新設計。雖然不間斷的改進貫穿了70、80 和90年代使其保持最新狀態，但是直到1995年的徹底重新設計和改裝才使得gmc貨車成為一款正統的現代機動車。
