德國KLEINKNECHT變壓器為各機械(xie)設備的電器控(kong)制(zhi)元件提(ti)供電源(yuan)。具有體積小、性能優、接線**、可靠方便的特點。

原理：KLEINKNECHT變壓(ya)器(qi)(qi)是變換交(jiao)流(liu)電(dian)(dian)壓(ya)、電(dian)(dian)流(liu)和阻(zu)抗的(de)器(qi)(qi)件，當初級線(xian)圈中(zhong)(zhong)通(tong)有交(jiao)流(liu)電(dian)(dian)流(liu)時，鐵(tie)芯(xin)（或磁芯(xin)）中(zhong)(zhong)便產生交(jiao)流(liu)磁通(tong)，使次級線(xian)圈中(zhong)(zhong)感(gan)應(ying)出電(dian)(dian)壓(ya)（或電(dian)(dian)流(liu)）。KLEINKNECHT變壓(ya)器(qi)(qi)由鐵(tie)芯(xin)（或磁芯(xin)）和線(xian)圈組(zu)成，線(xian)圈有兩(liang)個或兩(liang)個以上的(de)繞組(zu)，其中(zhong)(zhong)接電(dian)(dian)源的(de)繞組(zu)叫初級線(xian)圈，其余的(de)繞組(zu)叫次級線(xian)圈。

分類(lei)：按冷(leng)卻方式(shi)(shi)分類(lei)：干式(shi)(shi)（自(zi)冷(leng)）變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、油浸（自(zi)冷(leng)）變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、氟化物（蒸發冷(leng)卻）變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)。按防潮(chao)方式(shi)(shi)分類(lei)：開放式(shi)(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、灌封式(shi)(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、密(mi)封式(shi)(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)。按鐵(tie)芯(xin)(xin)(xin)或線圈結構分類(lei)：芯(xin)(xin)(xin)式(shi)(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)（插(cha)片鐵(tie)芯(xin)(xin)(xin)、型鐵(tie)芯(xin)(xin)(xin)、鐵(tie)氧體(ti)鐵(tie)芯(xin)(xin)(xin)）、殼式(shi)(shi)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)（插(cha)片鐵(tie)芯(xin)(xin)(xin)、型鐵(tie)芯(xin)(xin)(xin)、鐵(tie)氧體(ti)鐵(tie)芯(xin)(xin)(xin)）、環(huan)型變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、金屬箔(bo)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)。

按電源相數分類：單相變(bian)(bian)壓(ya)器(qi)、三相變(bian)(bian)壓(ya)器(qi)、多(duo)相變(bian)(bian)壓(ya)器(qi)。按用途分類：電源變(bian)(bian)壓(ya)器(qi)、調壓(ya)變(bian)(bian)壓(ya)器(qi)、音頻變(bian)(bian)壓(ya)器(qi)、中(zhong)頻變(bian)(bian)壓(ya)器(qi)、高頻變(bian)(bian)壓(ya)器(qi)、脈(mo)沖變(bian)(bian)壓(ya)器(qi)。
