如宜變頻器維修


變頻器修理

變頻器維修秘籍「口訣」

變頻維修別心急,放電以后再拆機;聞問診切很重要,方向對了再去搞;
輸入輸出與母線,PN結特性要體現;若有短路必有鬼,細查模塊不后悔;
加電之前看仔細,電壓加錯會炸機;加電以后無顯示,開關電源有問題;
過流故障很常見,真真假假需分辨;假需查霍爾互感,真需查驅動模塊;
欠壓過壓也常見,真假還是要分辨;假的需要查電源,真的需要查檢測;
過熱現象偶爾見,真熱假熱需判斷;真查驅動與負載;假查溫控與熱敏;
參數修改需謹慎;較好改前要備份;其他問題也很多,zui后就要放大招。
電路板上元器件,一個一個不放過。直插電阻看色環,四環五環代阻值,
貼片電阻看數字,阻值變大定有事;一個電容兩條腿,容量變小必有鬼,
電容測量用電橋,壞蛋休想再逍遙;電感以及變壓器,電橋測量好神奇;
二極管的種類多,測量方法都相同;反向截止正向通,簡單搞定中不中;
三極管及MOS管,板上就能測得轉;每個管子有三極,兩兩測量好壞覓;
IGBT以及可控硅,在線測量是大概;拆下來后仔細測,耐壓導通需都過;
開關電源明拓撲,搞懂原理才靠譜;輸入輸出要清楚,加對電壓不馬虎;
虛短虛斷會分析,搞定運算放大器;數字電路對地掃,阻值太小有蹊蹺;
電路若有單片機,以下三項要牢記:電源晶振和復位,一個不少才運行;
對比測試乃大招,絕處逢生意境高;
