The Basic Structure And Seven Advantages Of Toroidal Transformers

About the toroidal transformer, I think those who understand the electronic transformer know, toroidal transformer is widely used in all aspects, stepping motor, automatic door control, medical equipment, and even in the LED lighting, headphones and audio useful to the toroidal transformer.

The basic structure of toroidal transformers are:
1.the core: ordinary transformer silicon steel sheet stacked, coil core transformer core made of silicon steel tape winding. Its role in the primary coil AC current under the action of the formation of frequency alternating flux, through the core in the alternating flux induced by the electric potential in the secondary coil, the formation of low-voltage power. The iron core is the main body to complete the conversion of electrical energy, magnetic energy and electric energy.
2.winding (commonly known as the coil): generally with insulated flat copper wire or round copper wire in the winding mold winding. Contains primary, secondary (high voltage, low voltage) two groups. The primary coil is the original side of the electrical energy introduced into the transformer to complete part of the excitation process, the other part of the secondary coil to fill the electrical energy, the secondary coil is the magnetic energy into electrical energy and transmitted out. Coils are usually connected in accordance with certain electrical circuit connection methods.
3.the body insulation: including the initial level of insulation, inter-turn insulation and insulation with the core, and insulation between the shell. The materials used are cardboard, epoxy resin, various insulating materials, transformer oil, etc. Among them, transformer oil in addition to having a good insulation role, but also to help transformer heat dissipation role, to cool the operation of the core and coil.
The seven advantages of toroidal transformer:
1.Low standby energy consumption, lower no-load loss for standby to save more energy.
2.high efficiency, high energy conversion efficiency, efficient green power.
3.no high-frequency electromagnetic radiation, its industrial frequency electric field and industrial frequency magnetic field, the impact on the environment and the human body is completely negligible, is a healthy power supply.
4.low temperature characteristics, in the environment of minus 40 degrees can still start normally, and work for a long time.
5.Small internal resistance, strong anti-interference ability, small size, and high cost performance when making high-power power supply.
6.Excellent electrical performance, its anti-electrical strength and resistance to humidity and heat are much higher than the industry standard.
7.Good low temperature characteristics, some toroidal transformers can still start normally at minus 30 degrees.
