    高壓(ya)斷路器： 又稱高壓(ya)開(kai)關，它不僅可以(yi)切斷或(huo)閉(bi)合高壓(ya)電(dian)(dian)路中的(de)(de)(de)(de)空載電(dian)(dian)流和(he)負荷電(dian)(dian)流，而且當(dang)系統(tong)發生故障時，通過(guo)(guo)繼電(dian)(dian)保護裝置(zhi)的(de)(de)(de)(de)作用，切斷過(guo)(guo)負荷電(dian)(dian)流和(he)短路電(dian)(dian)流。母線加工機它具有相當(dang)完善的(de)(de)(de)(de)滅(mie)弧結構和(he)足夠的(de)(de)(de)(de)斷流能力。磁性元(yuan)件的(de)(de)(de)(de)設計(ji)是開(kai)關電(dian)(dian)源的(de)(de)(de)(de)重要(yao)部分，因(yin)為平面變(bian)壓(ya)器在(zai)提高開(kai)關電(dian)(dian)源的(de)(de)(de)(de)特性方面有著很(hen)大的(de)(de)(de)(de)優勢，因(yin)此(ci)近年來得(de)到了廣泛的(de)(de)(de)(de)應用。 　　

    對(dui)于一(yi)個理想的(de)變壓(ya)器(qi)來說，初級線(xian)圈(quan)所產(chan)生(sheng)的(de)磁(ci)通都(dou)穿過次(ci)級線(xian)圈(quan)，即沒有漏(lou)磁(ci)通。而(er)對(dui)普通變壓(ya)器(qi)來說，初級線(xian)圈(quan)所產(chan)生(sheng)的(de)磁(ci)通并(bing)非都(dou)穿過次(ci)級線(xian)圈(quan)，于是就產(chan)生(sheng)了漏(lou)感，電磁(ci)耦合的(de)緊密要求(qiu)也(ye)無(wu)法(fa)滿足(zu)。而(er)平面(mian)變壓(ya)器(qi)只有一(yi)匝網狀次(ci)級繞組，這(zhe)一(yi)匝繞組也(ye)不同(tong)于傳統的(de)漆包線(xian)，而(er)是一(yi)片銅皮，貼繞在多個同(tong)樣(yang)大小的(de)沖(chong)壓(ya)鐵(tie)氧體磁(ci)芯表面(mian)上。
