toroidal transformers turn to turn bad reasons:
Turn-to-turn short circuit is mainly caused by scraping line. To thread the handle
1. To change the metal threading device for the nylon threading device
2, set in the threading device on a section of PTFE sleeve, the line away from the casing, and metal does not touch
3. If the use of metal threading device, a day with cotton yarn and polishing paste grinding threading device.
other reasons
Core acute angle to round
Winding speed too fast, wire insulation caused by heat damage.
In the winding some care only is not have been in place, and some ignore the wire wheel is in the direction of rotation with the winding, if the wire wheel is locked, the wire wheel and the enameled wire friction produces a high temperature Will paint the film is damaged, as well as wire cover too much, enameled wire pulled out in advance when the tie knot, which is the most fatal.
