維修變頻器不可以忽略的點

咨詢熱線:15861509508

變頻器維修之前先記下各端子的連接部位,拍下照。以防時間長了沒修忘了安錯位置。IGBT和整流橋螺絲一定要擰緊。并且要打好硅脂,硅脂要買不假的。否則容易干!各銅排一定要安裝正確并釘緊!也不要擰擼了。

彈墊緊平了就差不多!各引線要布置好,不要挨上有散熱的器件上!各元件按原型號配置!插件要插好,不要松動!觸發器端不能帶電拔掉,也不能在未插入觸發器端時就啟動!不然炸機!

變頻器維修

更換主板和驅動板一定要校正參數:直流母線電壓實測要與顯示值一致!實測電流要與顯示電流一致!如果不符,要進入變頻器參數進行設置!一切都更換完了,如果沒有把握,要斷開直流母線電壓,單獨用低壓給IGBT上電或直流母線串入2個25W燈泡,(一個燈泡耐壓不夠)換電解電容要注意極性。

各硬件全上好、螺絲都擰好、銅排按規定上好后,仔細檢查一遍。接好供電后反復檢查一下有沒有接錯!輸入輸出不能接反!放置一年以上沒上電的變頻器一定不要直接上電,要用調壓器慢慢調到正常值,如果沒事,就空運行一小時左右。才確定交活!

維修變頻器時,還有一個重要的點:我們必須了解每個器件的名稱、用途、作用?,F在網絡發達,可以上網查!
