style="text-indent:25px">開關(guān)變壓器線圈之間存在漏感，是因為線圈之間存在漏磁通而產(chǎn)生的。江西小型變壓器測試</p><p style="text-indent:25px">拆過高頻變壓器的人都清楚，高頻變壓器的線圈都是由絕緣漆包裹的銅線繞成，層與層之間由絕緣膠帶纏繞，不留一絲縫隙，而高頻變壓器的絕緣線是由三層絕緣材質(zhì)包裹的銅線，雖然很薄，但卻能保證幾千伏的電壓無法擊穿。雖然高頻變壓器有這么強(qiáng)大的絕緣防護(hù)，但在測試時還是會有被高壓擊穿的變壓器，這是由什么原因造成的呢？經(jīng)過仔細(xì)的觀察，不難發(fā)現(xiàn)造成這種現(xiàn)象的主要原因是： 1、三層絕緣線與初級繞組間的交叉處沒有隔離，比如未穿套管等，在焊錫時三層絕緣線在被銅線導(dǎo)熱后，融傷了絕緣皮層，在后面工序測試時會產(chǎn)生很多高壓不良，而高壓測試是具有破壞性的測試，當(dāng)產(chǎn)品品質(zhì)處于高壓擊穿的臨界值時，多次測試也會出現(xiàn)高壓不良。 2、三層絕緣線與次級繞組間的交叉處沒有隔離，即使在焊錫時控制好，測試無高壓不良，但是產(chǎn)品在客戶處上波峰焊錫絲，針腳會再次受熱，同樣也會融傷絕緣層，造成高壓不良。江西小型變壓器測試</p><p
