當(dāng)變頻器出現(xiàn)缺相故障時(shí)，如何進(jìn)行檢測(cè)？

變頻器在工業(yè)應(yīng)用中廣泛使用，但在運(yùn)行過(guò)程中，缺相故障是一個(gè)常見且嚴(yán)重的問(wèn)題。缺相故障不僅會(huì)影響變頻器的正常運(yùn)行，還可能導(dǎo)致電機(jī)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(huì)發(fā)生輸入缺相故障。

輸出缺相：

變頻器的輸出端缺相會(huì)導(dǎo)致電機(jī)缺相運(yùn)行，電機(jī)在靜止時(shí)無(wú)法啟動(dòng)，運(yùn)行中缺相會(huì)導(dǎo)致電機(jī)電流增大1.2倍，發(fā)熱嚴(yán)重，震動(dòng)加劇，容易燒壞電機(jī)。

二、變頻器輸入缺相的檢測(cè)方法

硬件檢測(cè)：

使用硬件檢測(cè)是簡(jiǎn)單的方法。通過(guò)檢測(cè)電容C0上的電壓高低來(lái)反映R、S、T三相輸入是否缺相。當(dāng)發(fā)生缺相時(shí)，C0上的電壓降低，光耦器件不導(dǎo)通，A點(diǎn)信號(hào)為高電平，表示缺相發(fā)生。
