十年修復案例解決西門子變頻器電機運行無力故(gu)障(zhang)處理(li)：變(bian)(bian)頻器(qi)(qi)的保(bao)(bao)護(hu)功能主要有(you)過(guo)電(dian)流、過(guo)電(dian)壓、欠電(dian)壓、散(san)熱(re)(re)板過(guo)熱(re)(re)、外部(bu)報(bao)警輸入、逆變(bian)(bian)器(qi)(qi)過(guo)熱(re)(re)、電(dian)動(dong)機過(guo)載、逆變(bian)(bian)器(qi)(qi)過(guo)載、熔斷器(qi)(qi)燒斷、通信出錯、CPU出錯和運轉(zhuan)出錯等。變(bian)(bian)頻器(qi)(qi)在保(bao)(bao)護(hu)功能動(dong)作(zuo)后，面板上(shang)會(hui)有(you)相應的顯示，指示故(gu)障(zhang)原因。

   ; 過電流保護是電動機在加速、減速和恒速運轉時(shi)，如果逆(ni)變器輸(shu)出電流大于電流保護設定值時(shi)，會引(yin)起電流保護功能動作。

    這時應檢(jian)查電(dian)源電(dian)壓是否(fou)(fou)在允許的(de)范(fan)圍內，輸出回路是否(fou)(fou)短路，負載是否(fou)(fou)突然變(bian)(bian)化，加速時間是否(fou)(fou)不(bu)夠等(deng)情況。相應地，可調整電(dian)源電(dian)壓，檢(jian)查輸出回路絕(jue)緣(yuan)(yuan)(yuan)，用絕(jue)緣(yuan)(yuan)(yuan)電(dian)阻表(biao)測量電(dian)動機絕(jue)緣(yuan)(yuan)(yuan)，消除(chu)突變(bian)(bian)負載，延長加速時間，增大變(bian)(bian)頻器容量或查找噪聲干擾源并進行(xing)清除(chu)。

    引起過(guo)電壓的(de)原(yuan)(yuan)因與引起過(guo)電流的(de)原(yuan)(yuan)因基(ji)本相同(tong)，處(chu)理的(de)方(fang)法也基(ji)本相同(tong)。

    發生欠(qian)電(dian)(dian)(dian)壓(ya)保(bao)護(hu)時(shi)分兩種情況：一(yi)種是(shi)選擇了瞬(shun)時(shi)停(ting)電(dian)(dian)(dian)再(zai)起(qi)動功能(neng)的(de)，變頻器會自(zi)行起(qi)動，不輸(shu)出(chu)報(bao)警信(xin)號；另一(yi)種是(shi)電(dian)(dian)(dian)壓(ya)過低以至(zhi)不能(neng)維持(chi)逆變器控制電(dian)(dian)(dian)路電(dian)(dian)(dian)壓(ya)時(shi)，全部保(bao)護(hu)功能(neng)自(zi)動復(fu)位，這時(shi)應(ying)檢查(cha)電(dian)(dian)(dian)源電(dian)(dian)(dian)壓(ya)是(shi)否在(zai)允(yun)許的(de)極限內、電(dian)(dian)(dian)源是(shi)否斷相、同一(yi)電(dian)(dian)(dian)源系統中是(shi)否有大起(qi)動電(dian)(dian)(dian)流的(de)負載等，并進(jin)行相應(ying)故障處理。

    對外部報警輸入造成的保護動作，應檢查(cha)接線是(shi)(shi)否正確、負載(zai)是(shi)(shi)否太大(da)、環境溫度是(shi)(shi)否恰當、制動頻率是(shi)(shi)否太高，并(bing)進行(xing)故障處理。
