十年修復案例解決西門子變頻器電機運行無力：SIEMENS變(bian)頻(pin)器維(wei)修廠(chang)家(jia)，上海(hai)恒稅電氣(qi)有限(xian)公(gong)司，你的(de)選擇沒(mei)有錯(cuo)。公(gong)司自(zi)成立(li)以來，長期維(wei)修西門子變(bian)頻(pin)器及伺(si)服(fu)驅(qu)動器的(de)，觸(chu)摸屏(ping)，PLC，直流調速器等，積累了豐富的(de)維(wei)修經驗，對(dui)所維(wei)修的(de)機器建立(li)完善(shan)的(de)維(wei)修檔(dang)案(an)，所有我們維(wei)修的(de)機器我們都有完善(shan)的(de)參數備份(fen)，確保我們維(wei)修的(de)機器上機即能使用。

十年修復案例解決西門子變頻器電機運行無力故(gu)障處(chu)理：變(bian)頻器(qi)的(de)保護功能主要有(you)過(guo)電流(liu)、過(guo)電壓、欠電壓、散熱(re)板過(guo)熱(re)、外部報警輸入、逆(ni)變(bian)器(qi)過(guo)熱(re)、電動機(ji)過(guo)載、逆(ni)變(bian)器(qi)過(guo)載、熔斷(duan)器(qi)燒斷(duan)、通信(xin)出錯、CPU出錯和運轉出錯等。變(bian)頻器(qi)在保護功能動作后，面(mian)板上會有(you)相應的(de)顯(xian)示，指(zhi)示故(gu)障原因。

    過電(dian)流(liu)保(bao)護是電(dian)動機在加速、減速和(he)恒速運(yun)轉時，如果逆變(bian)器輸出電(dian)流(liu)大(da)于電(dian)流(liu)保(bao)護設(she)定值時，會引起電(dian)流(liu)保(bao)護功能動作。

    這時應檢查電(dian)源(yuan)電(dian)壓是(shi)否在允許(xu)的范(fan)圍內，輸出回(hui)路(lu)是(shi)否短(duan)路(lu)，負載是(shi)否突然變(bian)化，加(jia)(jia)速時間(jian)是(shi)否不(bu)夠等情況。相應地，可(ke)調整電(dian)源(yuan)電(dian)壓，檢查輸出回(hui)路(lu)絕緣，用(yong)絕緣電(dian)阻表測(ce)量電(dian)動機絕緣，消除(chu)突變(bian)負載，延長加(jia)(jia)速時間(jian)，增大變(bian)頻器容量或查找(zhao)噪(zao)聲(sheng)干擾(rao)源(yuan)并進行清除(chu)。

    引起過電(dian)壓(ya)的原因(yin)與引起過電(dian)流的原因(yin)基(ji)本相同(tong)，處理的方法也基(ji)本相同(tong)。

    發生欠電(dian)(dian)(dian)壓(ya)保護時分兩(liang)種情況：一(yi)種是(shi)(shi)選擇了瞬時停電(dian)(dian)(dian)再起(qi)動(dong)功能(neng)的，變頻器會自行(xing)起(qi)動(dong)，不(bu)輸出報警信號；另(ling)一(yi)種是(shi)(shi)電(dian)(dian)(dian)壓(ya)過(guo)低(di)以至不(bu)能(neng)維持逆(ni)變器控制電(dian)(dian)(dian)路電(dian)(dian)(dian)壓(ya)時，全部保護功能(neng)自動(dong)復(fu)位，這時應檢(jian)查電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)是(shi)(shi)否在允許的極限內、電(dian)(dian)(dian)源(yuan)是(shi)(shi)否斷相(xiang)、同一(yi)電(dian)(dian)(dian)源(yuan)系(xi)統中(zhong)是(shi)(shi)否有大起(qi)動(dong)電(dian)(dian)(dian)流的負載(zai)等，并進(jin)行(xing)相(xiang)應故障處理。

    對外(wai)部報警輸入(ru)造成的(de)保(bao)護動作，應檢(jian)查接線是(shi)否正確、負載是(shi)否太大、環境溫度(du)是(shi)否恰當(dang)、制動頻率是(shi)否太高，并進行故障處理。
