我國(guo)(guo)近幾年(nian)的(de)(de)(de)經(jing)濟迅速發(fa)展(zhan)(zhan)，國(guo)(guo)家(jia)經(jing)濟也(ye)日(ri)前發(fa)展(zhan)(zhan)和強大(da)。越來越多(duo)的(de)(de)(de)人走出國(guo)(guo)門，越來越多(duo)的(de)(de)(de)企業(ye)尋求國(guo)(guo)外發(fa)展(zhan)(zhan)，不斷發(fa)展(zhan)(zhan)外貿業(ye)務。變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)行業(ye)也(ye)不例外。一般變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)出口有(you)一些三相變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)、出口專(zhuan)用(yong)(yong)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)等(deng)(deng)。因為(wei)每個國(guo)(guo)家(jia)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)標準各不相同。美國(guo)(guo)等(deng)(deng)用(yong)(yong)120V電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)的(de)(de)(de)國(guo)(guo)家(jia),電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)防(fang)(fang)護重(zhong)(zhong)點(dian)在(zai)于防(fang)(fang)火；而(er)對于中國(guo)(guo)等(deng)(deng)用(yong)(yong)220V電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)的(de)(de)(de)國(guo)(guo)家(jia),電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)防(fang)(fang)護重(zhong)(zhong)點(dian)在(zai)于觸(chu)電(dian)(dian)(dian)(dian).從(cong)理論(lun)角度來說，電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)越高，線路(lu)上的(de)(de)(de)損耗就(jiu)越小(xiao)，而(er)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)越低越安全。所以在(zai)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)的(de)(de)(de)出口方(fang)向我們也(ye)需要注意(yi)到其電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)使用(yong)(yong)情況的(de)(de)(de)不同。無論(lun)是中小(xiao)企業(ye)的(de)(de)(de)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)廠(chang)家(jia)，還(huan)是大(da)型變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)廠(chang)。變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)出口已經(jing)成為(wei)日(ri)常加(jia)工(gong)生產的(de)(de)(de)一部分。這(zhe)種(zhong)為(wei)電(dian)(dian)(dian)(dian)網(wang)提供穩壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)的(de)(de)(de)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)在(zai)日(ri)常電(dian)(dian)(dian)(dian)網(wang)中也(ye)起著(zhu)重(zhong)(zhong)要的(de)(de)(de)作用(yong)(yong)。
