 為了用(yong)散(san)熱來消耗再生功率(lv)，需要在變頻(pin)(pin)器側(ce)安裝(zhuang)制(zhi)動(dong)(dong)電(dian)阻。為了改(gai)善制(zhi)動(dong)(dong)能力，不能期望靠增(zeng)加變頻(pin)(pin)器的容量來解(jie)決問題(ti)。請選用(yong)“制(zhi)動(dong)(dong)電(dian)阻”、“制(zhi)動(dong)(dong)單元(yuan)”或(huo)“功率(lv)再生變換器”等(deng)選件來改(gai)善變頻(pin)(pin)器的制(zhi)動(dong)(dong)容量。
七、當電機的旋轉(zhuan)速(su)度改變時，其輸(shu)出轉(zhuan)矩(ju)會怎樣
工頻電源(yuan)。由電網(wang)提供(gong)的動力電源(yuan)（商用電源(yuan)）。
起動(dong)(dong)電(dian)流。當電(dian)機開始運轉時(shi)，變(bian)頻(pin)器的(de)輸出電(dian)流、變(bian)頻(pin)器驅(qu)動(dong)(dong)時(shi)的(de)起動(dong)(dong)轉矩和大轉矩要(yao)小(xiao)于直接用工頻(pin)電(dian)源驅(qu)動(dong)(dong)。
我們經常聽(ting)到下面的(de)(de)說法：“電(dian)(dian)(dian)機在工頻(pin)(pin)(pin)(pin)(pin)(pin)電(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)時(shi)時(shi)，電(dian)(dian)(dian)機的(de)(de)起(qi)動和(he)加速沖擊(ji)(ji)很(hen)大(da)，而當使用(yong)變頻(pin)(pin)(pin)(pin)(pin)(pin)器供(gong)電(dian)(dian)(dian)時(shi)，這些沖擊(ji)(ji)就要(yao)弱(ruo)一(yi)些”。如果(guo)用(yong)大(da)的(de)(de)電(dian)(dian)(dian)壓(ya)和(he)頻(pin)(pin)(pin)(pin)(pin)(pin)率起(qi)動電(dian)(dian)(dian)機，例如使用(yong)工頻(pin)(pin)(pin)(pin)(pin)(pin)電(dian)(dian)(dian)網(wang)(wang)直(zhi)接供(gong)電(dian)(dian)(dian)，就會產生(sheng)一(yi)個大(da)的(de)(de)起(qi)動沖擊(ji)(ji)（大(da)的(de)(de)起(qi)動電(dian)(dian)(dian)流）。而當使用(yong)變頻(pin)(pin)(pin)(pin)(pin)(pin)器時(shi)，變頻(pin)(pin)(pin)(pin)(pin)(pin)器的(de)(de)輸出電(dian)(dian)(dian)壓(ya)和(he)頻(pin)(pin)(pin)(pin)(pin)(pin)率是(shi)逐漸加到電(dian)(dian)(dian)機上的(de)(de)，所以(yi)(yi)電(dian)(dian)(dian)機產生(sheng)的(de)(de)轉矩要(yao)小于工頻(pin)(pin)(pin)(pin)(pin)(pin)電(dian)(dian)(dian)網(wang)(wang)供(gong)電(dian)(dian)(dian)的(de)(de)轉矩值，所以(yi)(yi)西門子直流調速器6RA7087顯示報警F068維修變頻器驅(qu)動的電(dian)機起動電(dian)流要(yao)小些。
變頻器(qi)(qi)是(shi)應(ying)用變頻技術(shu)與微電(dian)(dian)(dian)子技術(shu)，通過(guo)改變電(dian)(dian)(dian)機(ji)工作電(dian)(dian)(dian)源頻率方式來控制交(jiao)流(liu)電(dian)(dian)(dian)動機(ji)的電(dian)(dian)(dian)力控制設備(bei)。變頻器(qi)(qi)主要由整流(liu)(交(jiao)流(liu)變直流(liu))、濾波、逆變(直流(liu)變交(jiao)流(liu))、制動單元(yuan)、驅動單元(yuan)、檢測單元(yuan)微處(chu)理(li)單元(yuan)等(deng)組成。變頻器(qi)(qi)靠內部IGBT的開斷來調(diao)整輸出(chu)電(dian)(dian)(dian)源的電(dian)(dian)(dian)壓和頻率，根據電(dian)(dian)(dian)機(ji)的實際需要來提(ti)供(gong)其所需要的電(dian)(dian)(dian)源電(dian)(dian)(dian)壓，進(jin)而達到節(jie)能(neng)、調(diao)速(su)的目的，另外，變頻器(qi)(qi)還有很多的保護功能(neng)，如過(guo)流(liu)、過(guo)壓、過(guo)載(zai)保護等(deng)等(deng)。
