工頻變壓器問題
今天工廠的設備主管找到我,給了一個工頻變壓器給我,說是壞了,看標示是EI54的矽鋼片,因為對工頻變壓器也不了解,具體現在可知的參數如附件所示.就是其中一個繞組開路了,請各位大俠幫忙看一下能否確認出變壓器的輸入,輸出功率應該是多少?我按照100V和200V輸入功率應該相同計算的輸入功率應該在170W.不知是否有問題,請大俠們賜教!

膠心是套裝?王字(兩條道?工字(一條道)?輸出電壓是空載電壓還是負載電壓?
具體我附照片上來.謝謝!

17V的是6歐姆啊.原理圖上有一個是沒PIN腳的,只是把兩個繞組在那個PIN上聯通!能講講怎么推出來的嗎?
這些數據非常接近你的變壓器,清你再測一下17伏繞組電阻,我用軟件計算怎么計算一言難盡.

你17V這個繞組電阻量錯了只有1點幾歐,這個變壓器功率只有二十幾瓦.初級只有三個抽頭,怎么原理圖有四個抽頭.你原理圖畫錯了,此變壓器中間有一層屏蔽此抽頭于其他引線不通,不是變壓器壞了,這個變壓器是100伏于200伏通用,初級并非0.1三股而是并成三股放止一股容易斷
我把細節拍照片上來了!因為PIN1和PIN2的接頭看上去都是鍍錫線樣的,如果是屏蔽的話怎么有兩個鍍錫線接頭!如果有不清楚我可以在拍照片上來!

你可用一個調壓器在初級慢慢加電壓看空載電流與輸出電壓證實變壓器是否壞,
按下圖加電壓
