西門子調速器勵磁模塊壞/6RA70修理,故障分析原理:一、輸入整流短路:1、生產線供電電壓不穩,電壓升高:這種情況是由于電壓不穩造成電壓超出了變頻器的輸入電源的規定范圍。或尖峰導致元件受損!這種現象一般會使生產線上多臺變頻器同時炸機!所以,應該保證良好的供電電源,盡量使變頻器工作在允許范圍之內而不是邊沿。雖然說變頻器有保護電路,但是有時來不及保護,要做好防浪涌的條件。變頻器生產線要安排合理,頻頻起動的大功率變頻器要與正常工作的中小功率變頻器分路安裝!如果線路浪涌較大,要在變頻器輸入端加裝輸入電抗器或浪涌濾波器。
2、變頻器防護不完善:使變頻器內進入雨水、潮濕、造成電路板導電。
3、整流橋和母線電容老化造成損壞!
二、驅動電路和IGBT電路:1、IGBT自身老化。2、變頻器外部短路、接地等。
三、環境造成的:過熱、導電粉塵、潮濕、引起的線路碳化,使驅動信號誤導通。
四、觸發端子松動,接觸不良。檢修時一定要把觸發端子插好,并且不要拔下觸以端子檢修變頻器。IGBT損壞大都會使驅動電路連帶損壞,千萬不要換上HGBT完事,要細心檢查驅動信號波形是否正常。
