臺達變頻器維修常見故障:散熱板分離散熱技術也是LENNZE變頻器的一個很大賣點,大家都知道常規(guī)變頻器都是有冷卻風扇散熱,但有些場合使用了散熱風扇后常常成為變頻器的一個常見故障點。這種現(xiàn)象主要在紡織工廠比較多見。紡織工廠空氣中的棉絮和化纖常常堵塞風扇,引起變頻器故障報警。而LENZE變頻器的散熱板分離散熱技術恰恰解決了這個問題。但我們也會碰到客戶在使用一段時間后出現(xiàn)變頻器帶不起重載的現(xiàn)象,從我們的經(jīng)驗分析也有可能是由于變頻器的散熱問題引起的,由于散熱的不充分,元器件更易老化,損耗更快。一般在這種情況下,更換老化器件能解決此問題。

此外,在實際應用中我們也可以依據(jù)變頻器的發(fā)光二極管的狀態(tài)判斷一下變頻器的狀態(tài)及故障,特別是在沒有面板的情況下這種判斷辦法更方便。一般在綠燈亮,紅燈滅的情況下是在控制面板的操作狀態(tài)下。綠燈閃爍,紅燈亮則是操作面板禁止控制。綠燈滅,紅燈一秒閃爍一次,此時變頻器為故障狀態(tài)。
