高壓電機廠家批發高(gao)壓電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)是(shi)(shi)指額(e)定電(dian)(dian)(dian)(dian)壓在1000V以上(shang)電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)。常使(shi)用用的是(shi)(shi)6000V和10000V電(dian)(dian)(dian)(dian)壓，由(you)于國外的電(dian)(dian)(dian)(dian)網不同，也(ye)有3300V和6600V的電(dian)(dian)(dian)(dian)壓等級。高(gao)壓電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)產生是(shi)(shi)由(you)于電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)功(gong)率(lv)與電(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)流的乘積成(cheng)正比，因此低壓電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)功(gong)率(lv)增大(da)到一定程度(如300KW/380V)電(dian)(dian)(dian)(dian)流受(shou)(shou)到導線的允許承受(shou)(shou)能(neng)力(li)的限制(zhi)就難(nan)以做大(da)，或成(cheng)本過(guo)高(gao)。需要通過(guo)提高(gao)電(dian)(dian)(dian)(dian)壓實現(xian)大(da)功(gong)率(lv)輸出。 高(gao)壓電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)優點是(shi)(shi)功(gong)率(lv)大(da)，承受(shou)(shou)沖擊(ji)能(neng)力(li)強；缺點是(shi)(shi)慣(guan)性大(da)，啟動和制(zhi)動都困(kun)難(nan)。

高壓電機廠家批發變頻器為低壓變頻器，輸入側采用變壓器將高壓變為低壓，將高壓電機換掉，采用特殊的低壓電機，電機的電壓水平多種多樣，沒有統一標準。
這種(zhong)做法由于采用低壓變頻器，容量(liang)也比(bi)(bi)較小(xiao)，對電(dian)網側的諧(xie)波(bo)較大，可以采用12脈沖(chong)整流(liu)減少諧(xie)波(bo)，但是(shi)滿足不了(le)對諧(xie)波(bo)的嚴格要求。在變頻器出現故障時，電(dian)機不能投入到(dao)工頻電(dian)網運行，在有(you)些不能停機的場合應用會有(you)問(wen)題。另外，電(dian)機和電(dian)纜都要更換，工程量(liang)比(bi)(bi)較大。

基本用途
高壓電(dian)動機(ji)(ji)(ji)(ji)(ji)(ji)可(ke)用于驅(qu)動各(ge)種不(bu)同(tong)機(ji)(ji)(ji)(ji)(ji)(ji)械(xie)之(zhi)用。如壓縮機(ji)(ji)(ji)(ji)(ji)(ji)、水泵、破(po)碎機(ji)(ji)(ji)(ji)(ji)(ji)、切削機(ji)(ji)(ji)(ji)(ji)(ji)床、運(yun)(yun)輸機(ji)(ji)(ji)(ji)(ji)(ji)械(xie)及其它設(she)備，供(gong)礦山、機(ji)(ji)(ji)(ji)(ji)(ji)械(xie)工(gong)(gong)業、石油化工(gong)(gong)工(gong)(gong)業、發電(dian)機(ji)(ji)(ji)(ji)(ji)(ji)等各(ge)種工(gong)(gong)業中作原(yuan)動機(ji)(ji)(ji)(ji)(ji)(ji)用。用以傳動鼓風機(ji)(ji)(ji)(ji)(ji)(ji)、磨(mo)煤機(ji)(ji)(ji)(ji)(ji)(ji)、軋鋼機(ji)(ji)(ji)(ji)(ji)(ji)、卷(juan)揚機(ji)(ji)(ji)(ji)(ji)(ji)的電(dian)動機(ji)(ji)(ji)(ji)(ji)(ji)應在訂貨時注明(ming)用途及技(ji)術(shu)要求，采用特殊(shu)的設(she)計以保(bao)障可(ke)靠運(yun)(yun)行。
