三星4500V型影碟机的电源变压器发生短路比较常见,然而由于维修配件难买,使许多维修人员束手无策。其实,该机电源变压器的绕组虽然复杂,但只要掌握窍门,自己绕制并不难,现将笔者多次绕制该变压器的体会介绍如下。 1.重绕220V初级绕组。该机电源变压器的初、次级绕组分别绕在两个塑料骨架上,220V初级绕组的塑料骨架较小,并插在次级绕组骨架的内层。重绕时先将变压器的硅钢片抽去(拆第1、第2片硅钢片时应特别小心),然后将220V初级绕组骨架从次级绕组骨架内向线圈绕组的轴心方向推出(做好记号),拆去初级短路绕组,用D0.25QQZ漆包线按原方向绕895T,再逆着原推出方向把初级绕组推回次级绕组塑料 Samsung 4500V DVD player power transformer short circuit is more common, however, due to difficult to repair parts, so many maintenance staff helpless. In fact, the machine power transformer winding though complex, but as long as the know-how, their own winding is not difficult, now I repeatedly winding the experience of the transformer introduced below. 1. Rewound 220V primary winding. The machine power transformer primary and secondary windings were wound on two plastic skeleton, 220V primary winding plastic skeleton smaller, and inserted in the inner layer of the secondary winding skeleton. Rewinding the first transformer silicon silicon removed (remove the first, the second silicon steel sheet should be particularly careful), and then the 220V primary winding skeleton from the secondary winding bobbin axis within the framework of the coil (mark ), Remove the primary short-circuit winding, with D0.25QQZ enameled wire around the original direction around 895T, and then against the original launch of the primary winding pushed back to secondary winding plastic
