工頻變壓器問題
今天工廠的設(shè)備主管找到我,給了一個(gè)工頻變壓器給我,說是壞了,看標(biāo)示是EI54的矽鋼片,因?yàn)閷?duì)工頻變壓器也不了解,具體現(xiàn)在可知的參數(shù)如附件所示.就是其中一個(gè)繞組開路了,請(qǐng)各位大俠幫忙看一下能否確認(rèn)出變壓器的輸入,輸出功率應(yīng)該是多少?我按照100V和200V輸入功率應(yīng)該相同計(jì)算的輸入功率應(yīng)該在170W.不知是否有問題,請(qǐng)大俠們賜教!
全部回復(fù)(16)

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(fù)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(gè)是沒PIN腳的,只是把兩個(gè)繞組在那個(gè)PIN上聯(lián)通!能講講怎么推出來的嗎?
這些數(shù)據(jù)非常接近你的變壓器,清你再測(cè)一下17伏繞組電阻,我用軟件計(jì)算怎么計(jì)算一言難盡.

你17V這個(gè)繞組電阻量錯(cuò)了只有1點(diǎn)幾歐,這個(gè)變壓器功率只有二十幾瓦.初級(jí)只有三個(gè)抽頭,怎么原理圖有四個(gè)抽頭.你原理圖畫錯(cuò)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(gè)變壓器是100伏于200伏通用,初級(jí)并非0.1三股而是并成三股放止一股容易斷
我把細(xì)節(jié)拍照片上來了!因?yàn)镻IN1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(gè)鍍錫線接頭!如果有不清楚我可以在拍照片上來!
