當變頻器出現缺相故障時,如何進行檢測?
變頻器在工業應用中廣泛使用,但在運行過程中,缺相故障是一個常見且嚴重的問題。缺相故障不僅會影響變頻器的正常運行,還可能導致電機損壞。
一、變頻器缺相故障的類型
輸入缺相:
變頻器的輸入端(R、S、T三相交流輸入)如果某一相因熔斷器或斷路器故障而斷開,就會發生輸入缺相故障。
輸出缺相:
變頻器的輸出端缺相會導致電機缺相運行,電機在靜止時無法啟動,運行中缺相會導致電機電流增大1.2倍,發熱嚴重,震動加劇,容易燒壞電機。
二、變頻器輸入缺相的檢測方法
硬件檢測:
使用硬件檢測是簡單的方法。通過檢測電容C0上的電壓高低來反映R、S、T三相輸入是否缺相。當發生缺相時,C0上的電壓降低,光耦器件不導通,A點信號為高電平,表示缺相發生。
