整流變壓器廠家解(jie)析整流變壓(ya)器的(de)交流

1.交(jiao)(jiao)流(liu)變交(jiao)(jiao)流(liu)：如變電(dian)(dian)(dian)站里(li)的交(jiao)(jiao)流(liu)變壓(ya)(ya)(ya)器(qi)(qi)。變壓(ya)(ya)(ya)器(qi)(qi)有(you)兩組(zu)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)。初(chu)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)和次(ci)(ci)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)。次(ci)(ci)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)在初(chu)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)外邊。當初(chu)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)通上交(jiao)(jiao)流(liu)電(dian)(dian)(dian)時，變壓(ya)(ya)(ya)器(qi)(qi)鐵芯(xin)產生交(jiao)(jiao)變磁(ci)場，次(ci)(ci)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)就產生感應電(dian)(dian)(dian)動勢(shi)。變壓(ya)(ya)(ya)器(qi)(qi)的線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)的匝(za)數比(bi)等于電(dian)(dian)(dian)壓(ya)(ya)(ya)比(bi)。例如：初(chu)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)是(shi)500匝(za)，次(ci)(ci)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)是(shi)250匝(za)，初(chu)級(ji)通上220V交(jiao)(jiao)流(liu)電(dian)(dian)(dian)，次(ci)(ci)級(ji)電(dian)(dian)(dian)壓(ya)(ya)(ya)就是(shi)110V。變壓(ya)(ya)(ya)器(qi)(qi)能(neng)降(jiang)壓(ya)(ya)(ya)也(ye)能(neng)升(sheng)壓(ya)(ya)(ya)。

2、交流(liu)(liu)變(bian)直流(liu)(liu)：如手機(ji)的充電(dian)器其實還是(shi)交流(liu)(liu)變(bian)交流(liu)(liu)，電(dian)壓降低了，再通(tong)過濾波電(dian)路把交流(liu)(liu)電(dian)變(bian)成直流(liu)(liu)電(dian)。

 3、直流(liu)變交(jiao)流(liu)：如一些設備(bei)的(de)UPS備(bei)用(yong)電(dian)(dian)源(yuan)首先要(yao)用(yong)電(dian)(dian)子元(yuan)件(jian)將直流(liu)電(dian)(dian)變為交(jiao)流(liu)電(dian)(dian)，然后(hou)用(yong)變壓器變換電(dian)(dian)壓。這(zhe)個(ge)設備(bei)叫逆(ni)(ni)變器。它由逆(ni)(ni)變橋(qiao)、控制邏輯和(he)濾波電(dian)(dian)路組成.
