西門子6SE70變頻器開機報警無法復位;變頻器日常維護過程中,經常遇到各種各樣的問題,如外圍線路問題,參數設定不良或機械故障。如果是變頻器出現故障,如何去判斷是哪一部分問題,在這里略作介紹。
一、靜態測試
1、測試整流電路
找到變頻器內部直流電源的P端和N端,將萬用表調到電阻X10檔,紅表棒接到P,黑表棒分別依到R、S、T,應該有大約幾十歐的阻值,且基本平衡。相反將黑表棒接到P端,紅表棒依次接到R、S、T,有一個接近于無窮大的阻值。將紅表棒接到N端,重復以上步驟,都應得到相同結果。如果有以下結果,可以判定電路已出現異常,A.阻值三相不平衡,可以說明整流橋故障。B.紅表棒接P端時,電阻無窮大,可以斷定整流橋故障或起動電阻出現故障。
2、測試逆變電路
將紅表棒接到P端,黑表棒分別接U、V、W上,應該有幾十歐的阻值,且各相阻值基本相同,反相應該為無窮大。將黑表棒接到N端,重復以上步驟應得到相同結果,否則可確定逆變模塊故障 二、動態測試 在靜態測試結果正常以后,才可進行動態測試,即上電試機。在上電前后必須注意以下幾點: 1、上電之前,須確認輸入電壓是否有誤,將380V電源接入220V級變頻器之中會出現炸機(炸電容、壓敏電阻、模塊等)。
2、檢查變頻器各接播口是否已正確連接,連接是否有松動,連接異常有時可能導致變頻器出現故障,嚴重時會出現炸機等情況。
3、上電后檢測故障顯示內容,并初步斷定故障及原因。
4、如未顯示故障,首先檢查參數是否有異常,并將參數復歸后,進行空載(不接電機)情況下啟動變頻器,并測試U、V、W三相輸出電壓值。如出現缺相、三相不平衡等情況,則模塊或驅動板等有故障
5、在輸(shu)出電壓正常(無缺相、三(san)相平衡)的(de)情況下(xia),帶(dai)載測試(shi)。測試(shi)時,好(hao)是滿負載測試(shi)。
