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)(dian)壓(ya)調(diao)節器的(de)工作原(yuan)理：由于發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)與(yu)發(fa)動(dong)(dong)(dong)機(ji)的(de)傳動(dong)(dong)(dong)比固定(ding)，所以發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)的(de)轉(zhuan)速將(jiang)隨(sui)發(fa)動(dong)(dong)(dong)機(ji)轉(zhuan)速的(de)變(bian)(bian)化而變(bian)(bian)化。汽(qi)車在運行過程中，發(fa)動(dong)(dong)(dong)機(ji)轉(zhuan)速變(bian)(bian)化范圍(wei)很(hen)大，發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)的(de)端電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)也將(jiang)隨(sui)發(fa)動(dong)(dong)(dong)機(ji)的(de)轉(zhuan)速變(bian)(bian)化而在很(hen)大范圍(wei)內變(bian)(bian)化。發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)對用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)設備供(gong)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)求其電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)穩定(ding)，所以為(wei)使電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)始終保持在某(mou)一數值(zhi)基本不變(bian)(bian)，就必須(xu)對發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)的(de)輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)進行調(diao)節。

雷克薩斯ES(進口)簡介

雷(lei)克薩斯(si)ES是(shi)LEXUS歷史上最(zui)成功(gong)、銷(xiao)量最(zui)高(gao)的(de)車(che)型之一。雷(lei)克薩斯(si)ES在(zai)國(guo)際市場上早已成為豪(hao)華、優雅、舒適的(de)代名詞(ci)。雷(lei)克薩斯(si)ES車(che)型延續雷(lei)克薩斯(si)全新家族式設計，鋒銳動感的(de)紡(fang)錘形格柵與醒目的(de)L型LED日間行車(che)燈共(gong)同勾(gou)勒出大氣卻不失動感的(de)車(che)頭布局。
