變頻器發熱原因

變頻器和電機本身問題

電(dian)機(ji)用(yong)久(jiu)了(le)，不(bu)排除絕緣性能(neng)(neng)不(bu)好(hao)，或者軸承卡(ka)滯(zhi)，本(ben)身可能(neng)(neng)會出現(xian)大電(dian)流而(er)發熱(re)。電(dian)機(ji)和(he)負載之間的連軸，也可能(neng)(neng)有磨損，或者電(dian)機(ji)三相不(bu)平衡，電(dian)機(ji)的固(gu)定裝置(zhi)松動等等，會引(yin)起(qi)異常聲響和(he)發熱(re)。

變(bian)頻(pin)(pin)(pin)器(qi)某些元件老化，或者(zhe)矢(shi)量參數(shu)和電機(ji)匹配上有偏離(li)，或者(zhe)轉矩提升等(deng)參數(shu)設置過(guo)大，或者(zhe)加減速(su)時(shi)間過(guo)短，變(bian)頻(pin)(pin)(pin)器(qi)載波頻(pin)(pin)(pin)率太小(xiao)，都可能引起電機(ji)和變(bian)頻(pin)(pin)(pin)器(qi)一起發熱。

電機和(he)變頻器(qi)(qi)之間的連接(jie)線，一(yi)般不宜太長(chang)了，不然會產生衰減和(he)波形(xing)畸(ji)變，如果要(yao)使用(yong)，也應該使用(yong)變頻器(qi)(qi)，西(xi)門子(zi)V120變頻器(qi)(qi)價格，外(wai)加(jia)電抗器(qi)(qi)來(lai)處(chu)理。

有(you)些需(xu)要快速剎車的場合(he)，需(xu)要根據制(zhi)(zhi)(zhi)動功率選購合(he)適的制(zhi)(zhi)(zhi)動電阻和制(zhi)(zhi)(zhi)動單元等配件。

明(ming)泰電(dian)(dian)氣（蘇州）有限公司是(shi)正泰集團在蘇州地(di)區一家(jia)授權的(de)經銷企業，西門子V120變頻(pin)器(qi)(qi)報價，連續十(shi)年(nian)銷量居正泰營銷網絡名，公司主要(yao)經營“正泰”牌配電(dian)(dian)電(dian)(dian)器(qi)(qi)、控制電(dian)(dian)器(qi)(qi)、終端電(dian)(dian)器(qi)(qi)、電(dian)(dian)源電(dian)(dian)器(qi)(qi)、電(dian)(dian)力電(dian)(dian)子、儀器(qi)(qi)儀表、建(jian)筑電(dian)(dian)器(qi)(qi)、高(gao)壓電(dian)(dian)器(qi)(qi)及成(cheng)套設備(bei)。

電機是設備運行的心臟，幾乎是一切負載的動力源。在設計設備選型的時候，需要綜合考慮到負載需要的扭矩和功率，從而選擇合適的電機功率和扭矩，如果電機的容量選小了，西門子V120變頻器哪家好，相當于小馬拉重車，當然電機本身就處于超載工作狀態工作，本身會嚴重發熱。

明泰(tai)電(dian)(dian)(dian)(dian)氣（蘇(su)州(zhou)）有限公(gong)司(si)是正泰(tai)集團在蘇(su)州(zhou)地區一家授權的(de)經(jing)銷企(qi)業，連續十年銷量居正泰(tai)營銷網絡(luo)名(ming)，公(gong)司(si)主要經(jing)營“正泰(tai)”牌配電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)器、控制(zhi)電(dian)(dian)(dian)(dian)器、終(zhong)端(duan)電(dian)(dian)(dian)(dian)器、電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)器、電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)子(zi)、儀器儀表、建筑電(dian)(dian)(dian)(dian)器、高壓(ya)電(dian)(dian)(dian)(dian)器及成(cheng)套設備(bei)。

變頻電機和變頻器不(bu)經(jing)過調試就直接連(lian)在一起使用。
