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，給大家具體聊聊這塊，希望對大家能有幫助。

　　對于3KV、6KV、10KV電(dian)(dian)(dian)壓(ya)(ya)(ya)等(deng)級的電(dian)(dian)(dian)機(ji)(ji)稱為高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)電(dian)(dian)(dian)機(ji)(ji)，用(yong)(yong)(yong)于這類電(dian)(dian)(dian)機(ji)(ji)調速(su)的變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)稱為高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)。國外(wai)對此電(dian)(dian)(dian)壓(ya)(ya)(ya)等(deng)級的變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)稱為中(zhong)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)。在(zai)(zai)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)推出(chu)(chu)前，大(da)功(gong)(gong)率(lv)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)交(jiao)流異步電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)如需采用(yong)(yong)(yong)變(bian)(bian)(bian)(bian)頻(pin)(pin)調速(su)傳動(dong)(dong)(dong)(dong)，有兩種方法(fa)，一是靠低壓(ya)(ya)(ya)器(qi)(qi)(qi)件功(gong)(gong)率(lv)單(dan)元串(chuan)聯組成(cheng)(cheng)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)，如羅(luo)賓康公(gong)司(si)的高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)，由于控(kong)制(zhi)(zhi)復雜，功(gong)(gong)率(lv)器(qi)(qi)(qi)件太多(duo)而使得(de)其(qi)(qi)可(ke)靠性下降，同時每個功(gong)(gong)率(lv)單(dan)元均為雙電(dian)(dian)(dian)平結(jie)構，需要至少采用(yong)(yong)(yong)多(duo)重(zhong)化技術(shu)才能(neng)滿足諧波標(biao)準要求(qiu)。另一種就是“高(gao)(gao)(gao)(gao)一低一高(gao)(gao)(gao)(gao)”變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)，通過(guo)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)將高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)低壓(ya)(ya)(ya)(一般為690V)，在(zai)(zai)低壓(ya)(ya)(ya)側變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)，再由升(sheng)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)升(sheng)至和(he)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)相(xiang)匹(pi)配的電(dian)(dian)(dian)壓(ya)(ya)(ya)，組成(cheng)(cheng)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)交(jiao)流調速(su)傳動(dong)(dong)(dong)(dong)裝(zhuang)置。隨著耐(nai)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)大(da)功(gong)(gong)率(lv)晶體管( HV-IGBT，IGCT)的推出(chu)(chu)，近年來很(hen)多(duo)公(gong)司(si)紛紛推出(chu)(chu)了高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)，其(qi)(qi)特點足變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)輸出(chu)(chu)可(ke)直接接入高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)，無需 變(bian)(bian)(bian)(bian)頻(pin)(pin)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)，也稱高(gao)(gao)(gao)(gao)一高(gao)(gao)(gao)(gao)變(bian)(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)，現 大(da)可(ke)用(yong)(yong)(yong)于7500kW異步電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)的速(su)度和(he)轉矩控(kong)制(zhi)(zhi)。
