我國(guo)(guo)近幾年的(de)(de)(de)經濟迅速發展(zhan)，國(guo)(guo)家經濟也(ye)日前發展(zhan)和(he)強大。越(yue)來(lai)越(yue)多的(de)(de)(de)人(ren)走出國(guo)(guo)門，越(yue)來(lai)越(yue)多的(de)(de)(de)企業尋求(qiu)國(guo)(guo)外發展(zhan)，不(bu)斷發展(zhan)外貿業務。變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)行業也(ye)不(bu)例外。一(yi)般變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)出口(kou)(kou)有一(yi)些(xie)三相變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)、出口(kou)(kou)專(zhuan)用(yong)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)等。因為(wei)每(mei)個(ge)國(guo)(guo)家的(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)標準(zhun)各不(bu)相同。美國(guo)(guo)等用(yong)120V電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)(de)國(guo)(guo)家,電(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)防護重點(dian)在(zai)于防火(huo)；而(er)對于中國(guo)(guo)等用(yong)220V電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)(de)國(guo)(guo)家,電(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)防護重點(dian)在(zai)于觸(chu)電(dian)(dian)(dian).從理(li)論(lun)角度(du)來(lai)說，電(dian)(dian)(dian)壓(ya)(ya)(ya)越(yue)高，線路上的(de)(de)(de)損耗就越(yue)小，而(er)電(dian)(dian)(dian)壓(ya)(ya)(ya)越(yue)低越(yue)安(an)全。所以在(zai)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)(de)(de)出口(kou)(kou)方向我們也(ye)需要注意到其電(dian)(dian)(dian)壓(ya)(ya)(ya)使用(yong)情況(kuang)的(de)(de)(de)不(bu)同。無論(lun)是(shi)中小企業的(de)(de)(de)壓(ya)(ya)(ya)器(qi)(qi)廠家，還是(shi)大型變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)廠。變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)出口(kou)(kou)已經成為(wei)日常加(jia)工生(sheng)產的(de)(de)(de)一(yi)部分。這種(zhong)為(wei)電(dian)(dian)(dian)網(wang)提供(gong)穩(wen)壓(ya)(ya)(ya)電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)(de)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)在(zai)日常電(dian)(dian)(dian)網(wang)中也(ye)起著重要的(de)(de)(de)作用(yong)。
