生活中很多人應該都聽過高壓變頻器，但是對它的具體分類應該是不太了解的， 小編就以河南高壓變頻器為例，給大家(jia)具體聊聊這(zhe)塊，希望對(dui)大家(jia)能有幫助(zhu)。

　　對于3KV、6KV、10KV電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)等級(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)機(ji)稱為高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)機(ji)，用于這類(lei)電(dian)(dian)(dian)(dian)(dian)機(ji)調(diao)速(su)(su)的(de)(de)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)稱為高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)。國外對此電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)等級(ji)的(de)(de)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)稱為中壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)。在高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)推(tui)出前，大功(gong)率(lv)(lv)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)交(jiao)流異步電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)如(ru)需采用變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)調(diao)速(su)(su)傳動(dong)，有兩種(zhong)方(fang)法(fa)，一(yi)是靠(kao)低壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)件功(gong)率(lv)(lv)單元(yuan)串(chuan)聯組成(cheng)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)，如(ru)羅賓康公(gong)司的(de)(de)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)，由于控制復(fu)雜，功(gong)率(lv)(lv)器(qi)(qi)(qi)件太多而使得其(qi)可靠(kao)性下(xia)降，同時每個功(gong)率(lv)(lv)單元(yuan)均為雙電(dian)(dian)(dian)(dian)(dian)平結構，需要至(zhi)少采用多重(zhong)化技(ji)術(shu)才能滿足(zu)諧波標準要求。另(ling)一(yi)種(zhong)就是“高(gao)(gao)一(yi)低一(yi)高(gao)(gao)”變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)，通(tong)過(guo)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)將高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)低壓(ya)(ya)(ya)(ya)(ya)(ya)(一(yi)般為690V)，在低壓(ya)(ya)(ya)(ya)(ya)(ya)側變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)，再由升壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)升至(zhi)和高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)相(xiang)匹配的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)，組成(cheng)高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)交(jiao)流調(diao)速(su)(su)傳動(dong)裝置。隨(sui)著耐高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)大功(gong)率(lv)(lv)晶體管( HV-IGBT，IGCT)的(de)(de)推(tui)出，近年來(lai)很多公(gong)司紛紛推(tui)出了高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)，其(qi)特點(dian)足(zu)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)輸出可直(zhi)接(jie)接(jie)入高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)，無(wu)需 變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)，也稱高(gao)(gao)一(yi)高(gao)(gao)變(bian)(bian)(bian)(bian)頻(pin)(pin)(pin)器(qi)(qi)(qi)，現 大可用于7500kW異步電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)的(de)(de)速(su)(su)度和轉矩控制。
