XP Inductors And Transformer

Most of the home power amplifier power supply using a toroidal transformers . Ring transformer has a small magnetic leakage, high conversion efficiency, wide frequency response characteristics, can improve the amplifier sound quality. If the toroidal transformer burned, and can not buy the original model to replace, then only take the method of manual winding system to copy. The following manual winding method.

1. Remove the old windings

With the scissors along the center line on the circumference of the primary system will be a series of layers of the coil, and then cut off the coil stripping the core, then count the number of roots that the total number of turns.

2. The ring core is insulated

The toroidal core of toroidal transformers manufacturers was dipped in an insulating paint, dried out in a few minutes, and dried in an oven. And then in the inner and outer circumference of each layer of adhesive tape, and then the width of the cellophane into a strip of 2cm, the core wrapped around a layer, and double-sided tape adhesive joints.

3. Shuttle production

In order to facilitate manual operation, must be made of a special winding wire edge. It can be made of plastic sheet or stainless steel sheet, preferably 8 times the circumference of a single strand turns, the width is less than the annular core diameter of about 2cm.

4. Winding coil

First around the primary winding, take and the original diameter similar to the high-quality high-strength enameled wire, two-wire and wound in the "shape" -shaped shuttle, the number of turns to meet the requirements cut. The bobbin is attached to the outer circumference of the annular core with a double-sided adhesive, and the bobbin is wound around the inner hole of the annular core. A layer of the coil around, brush on a layer of insulating paint (conducive to positioning and insulation coil), and wrapped with a layer of cellophane, and then around the second layer of the coil. Around the good, the two ends of the coil head to tail in series, the other two lines with a soft wire leads to lead, and do insulation. In the primary group plus a layer of interlayer insulation paper and then around the secondary winding, winding method and the primary winding around the law similar.

After all the windings are wound, place the toroidal transformer in the oven for a period of time. And then in the outermost layer with a thick layer of insulating paper wrap, toroidal transformer production is completed.
