In several low-frequency transformers, the toroidal transformer working hot problem is slight, because the toroidal transformer itself low temperature rise, heat dissipation is fast, so the hot is not serious. But can you be sure that the quality of the toroidal transformer you bought is up to standard? If you buy a poor quality ring transformer, then the problem can be serious.
From the building technology point of view, if the ring transformer building technology is not enough, it will cause a small part of the short circuit phenomenon, light work hot serious, heavy burn transformer.
From the material point of view, it is mainly iron core and winding. All copper wire has the best electrical conductivity and the lowest heat, followed by copper-covered aluminum wire, and all aluminum wire burns the most serious. The quality of the iron core also has a choice, the simplest way to judge the quality of the iron core is to wind up a certain number of turns of the coil in accordance with the design scheme of the transformer, and pass the corresponding size of alternating current. Measure the size of the current to judge the quality of the core, and the quality of the small current is better.
