Toroidal transformer test is not the same as low frequency EI potting transformer?

Yes, the toroidal transformer also belongs to a kind of low-frequency transformer, in which the toroidal transformer oil the following advantages: toroidal transformer core toroidal transformer is made of high-quality cold-rolled silicon steel sheet (sheet thickness is generally 0.35mm or less), seamlessly rolled into, which makes its core performance superior to the traditional stacked-sheet type core. Toroidal transformer coils are evenly wound on the core, the direction of the magnetic lines of force generated by the coils and the core magnetic circuit is almost completely overlap, compared with the stacked pieces of excitation energy and core loss will be reduced by 25%, which brings the following series of advantages.

1) high efficiency core without air gap, stacked coefficient can be as high as 95%

more than the core permeability can be taken as 1.5 ~ 1.8T (laminated core can only be taken as 1.2 ~ 1.4T), the electrical efficiency of 95% or more, the no-load current is only 10% of the laminated type.

2) small dimensions, light weight toroidal transformer than stacked transformer weight can be reduced by half, as long as the core cross-sectional area is equal to keep the toroidal transformer is easy to change the core length, width, height ratio, can be designed to meet the requirements of the dimensions.

3) less magnetic interference toroidal transformer core has no air gap, the windings are uniformly wound in the ring on the core, this structure leads to a small leakage, electromagnetic radiation is also small, without the need to add another shielding can be used for high sensitivity electronic equipment, such as applications in low-level amplifiers and medical equipment.

4) vibration noise is small iron core without air gap can reduce the noise of the core induction vibration, winding uniform tightly wrapped around the annular core, effectively reducing the magnetostriction caused by the "hum" sound.

5) low operating temperature due to iron loss can be done 1.1W/kg, iron loss is very small, low temperature rise of the core, the windings in the lower temperature of the core on the heat dissipation is good, so the transformer temperature rise is low.

6) easy to install toroidal transformer only the center of a mounting screw, especially easy in electronic equipment for rapid installation and removal.

Can it be adopted?
