我國(guo)近幾年的(de)(de)(de)經(jing)(jing)(jing)濟迅速(su)發(fa)展，國(guo)家(jia)經(jing)(jing)(jing)濟也(ye)(ye)日前發(fa)展和強大(da)(da)。越(yue)(yue)(yue)來(lai)越(yue)(yue)(yue)多(duo)的(de)(de)(de)人走出(chu)(chu)國(guo)門，越(yue)(yue)(yue)來(lai)越(yue)(yue)(yue)多(duo)的(de)(de)(de)企業(ye)(ye)尋求國(guo)外發(fa)展，不斷發(fa)展外貿業(ye)(ye)務。變(bian)(bian)壓(ya)(ya)器(qi)行(xing)業(ye)(ye)也(ye)(ye)不例外。一般(ban)變(bian)(bian)壓(ya)(ya)器(qi)出(chu)(chu)口(kou)(kou)有一些三相(xiang)變(bian)(bian)壓(ya)(ya)器(qi)、出(chu)(chu)口(kou)(kou)專用(yong)(yong)(yong)變(bian)(bian)壓(ya)(ya)器(qi)等(deng)。因為(wei)每個國(guo)家(jia)的(de)(de)(de)電(dian)壓(ya)(ya)標準(zhun)各不相(xiang)同。美國(guo)等(deng)用(yong)(yong)(yong)120V電(dian)壓(ya)(ya)的(de)(de)(de)國(guo)家(jia),電(dian)器(qi)的(de)(de)(de)防(fang)護(hu)重點在(zai)(zai)于(yu)防(fang)火；而對于(yu)中(zhong)(zhong)國(guo)等(deng)用(yong)(yong)(yong)220V電(dian)壓(ya)(ya)的(de)(de)(de)國(guo)家(jia),電(dian)器(qi)的(de)(de)(de)防(fang)護(hu)重點在(zai)(zai)于(yu)觸電(dian).從理論角度來(lai)說，電(dian)壓(ya)(ya)越(yue)(yue)(yue)高，線(xian)路(lu)上的(de)(de)(de)損耗就越(yue)(yue)(yue)小(xiao)，而電(dian)壓(ya)(ya)越(yue)(yue)(yue)低越(yue)(yue)(yue)安全。所以(yi)在(zai)(zai)變(bian)(bian)壓(ya)(ya)器(qi)的(de)(de)(de)出(chu)(chu)口(kou)(kou)方向我們(men)也(ye)(ye)需要注意到其電(dian)壓(ya)(ya)使用(yong)(yong)(yong)情況(kuang)的(de)(de)(de)不同。無論是中(zhong)(zhong)小(xiao)企業(ye)(ye)的(de)(de)(de)壓(ya)(ya)器(qi)廠家(jia)，還是大(da)(da)型變(bian)(bian)壓(ya)(ya)器(qi)廠。變(bian)(bian)壓(ya)(ya)器(qi)出(chu)(chu)口(kou)(kou)已經(jing)(jing)(jing)成為(wei)日常加工生產的(de)(de)(de)一部分(fen)。這種(zhong)為(wei)電(dian)網(wang)提供穩壓(ya)(ya)電(dian)壓(ya)(ya)的(de)(de)(de)變(bian)(bian)壓(ya)(ya)器(qi)在(zai)(zai)日常電(dian)網(wang)中(zhong)(zhong)也(ye)(ye)起著重要的(de)(de)(de)作用(yong)(yong)(yong)。
