變頻器是一種可以調節和改變電壓和頻率的電源，電機是該電源的負載。只要參數匹配，兩者相互使用就沒有問題，也不會相互傷害。

　　普通異步電(dian)(dian)動機(ji)(ji)(ji)的散熱取決于電(dian)(dian)動機(ji)(ji)(ji)底(di)部后面的風(feng)扇(shan)。如果電(dian)(dian)機(ji)(ji)(ji)長時間(jian)低于電(dian)(dian)機(ji)(ji)(ji)額定頻(pin)率運行，電(dian)(dian)機(ji)(ji)(ji)轉速(su)低，風(feng)機(ji)(ji)(ji)吹入的風(feng)量(liang)很小，導致電(dian)(dian)機(ji)(ji)(ji)散熱不良。如果太熱，馬達就(jiu)會燒壞。如果電(dian)(dian)機(ji)(ji)(ji)發生故障，電(dian)(dian)機(ji)(ji)(ji)電(dian)(dian)流將增(zeng)加(jia)。如果超(chao)過變(bian)(bian)頻(pin)器(qi)的Z電(dian)(dian)流，河(he)南變(bian)(bian)頻(pin)器(qi)將受到保護，停止輸(shu)出并向用(yong)戶報告故障代碼。

　　鄭州變頻器(qi)導致電機燒毀的原因是什么(me)?

　　事實上，電(dian)(dian)機(ji)故(gu)障并不是電(dian)(dian)機(ji)本身的原因。主要(yao)是變頻(pin)(pin)(pin)器調試不規范或使用(yong)變頻(pin)(pin)(pin)電(dian)(dian)機(ji)時使用(yong)非變頻(pin)(pin)(pin)電(dian)(dian)機(ji)造成的。主要(yao)情況如下：

　　河南(nan)變頻器(qi)維護(hu)：變頻器(qi)導致電機(ji)燒毀(hui)的原(yuan)因是(shi)什么?

　　1、變頻電機采用普通電機。

　　由于普(pu)通(tong)電(dian)機(ji)的冷(leng)卻(que)風扇(shan)與(yu)轉(zhuan)軸(zhou)相(xiang)連(lian)，當用變頻(pin)器(qi)調速(su)時，轉(zhuan)速(su)不(bu)穩定，達不(bu)到電(dian)機(ji)的額(e)定轉(zhuan)速(su)，冷(leng)卻(que)風扇(shan)不(bu)能發(fa)揮正(zheng)常(chang)作用，導致電(dian)機(ji)冷(leng)卻(que)不(bu)良(liang);此外，普(pu)通(tong)電(dian)機(ji)未按(an)變頻(pin)要求設計，導致電(dian)機(ji)發(fa)熱(re)或(huo)燃燒。

　　2、變頻(pin)電機未經調(diao)試直接(jie)與變頻(pin)器連(lian)接(jie)。

　　鄭州變(bian)頻(pin)器(qi)通(tong)過兩種方(fang)式(shi)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)電(dian)(dian)(dian)機(ji)(ji)(ji)Z：矢(shi)量(liang)(liang)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)和(he)(he)v/f曲(qu)線控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。每個控(kong)(kong)(kong)制(zhi)(zhi)(zhi)模式(shi)應 控(kong)(kong)(kong)制(zhi)(zhi)(zhi)電(dian)(dian)(dian)機(ji)(ji)(ji)類型(同步(bu)、異(yi)步(bu)、帶或不帶編碼器(qi))。電(dian)(dian)(dian)機(ji)(ji)(ji)額定(ding)功率(lv)(lv)。額定(ding)電(dian)(dian)(dian)壓。額定(ding)電(dian)(dian)(dian)流(liu)。速度(du)(du)或極數。額定(ding)頻(pin)率(lv)(lv)。Z高(gao)工作頻(pin)率(lv)(lv)。電(dian)(dian)(dian)機(ji)(ji)(ji)啟動和(he)(he)停止的加速和(he)(he)減速時(shi)間。變(bian)頻(pin)器(qi)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)電(dian)(dian)(dian)機(ji)(ji)(ji)的保護方(fang)式(shi)和(he)(he)保護比例系數。荷載波頻(pin)率(lv)(lv)至(zhi)關重要。設置這(zhe)些參(can)數后(hou)，選(xuan)擇(ze)是(shi)使用矢(shi)量(liang)(liang)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)還是(shi)v/f控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。選(xuan)擇(ze)矢(shi)量(liang)(liang)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)時(shi)，電(dian)(dian)(dian)機(ji)(ji)(ji)應具有空(kong)載和(he)(he)變(bian)頻(pin)器(qi)匹(pi)配的動態自(zi)學(xue)習或負載靜態自(zi)學(xue)習。自(zi)學(xue)習后(hou)，電(dian)(dian)(dian)機(ji)(ji)(ji)與變(bian)頻(pin)器(qi)配合，充分發揮矢(shi)量(liang)(liang)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)的精(jing)度(du)(du);選(xuan)擇(ze)v/f控(kong)(kong)(kong)件時(shi)，不需要自(zi)學(xue)習。參(can)數調整后(hou)，可直接通(tong)電(dian)(dian)(dian)。

　　3、河南變(bian)頻(pin)電機風機運行方向與風機上標明(ming)的旋轉方向不一致。

　　風扇無法工作，導致電(dian)機(ji)散(san)熱(re)不良，電(dian)機(ji)產生的熱(re)量(liang)無法散(san)發(fa)(fa)，導致電(dian)機(ji)發(fa)(fa)熱(re)或(huo)燃燒。

　　4、以(yi)上三種(zhong)情況中，2例和3例發(fa)生率高。
