O que é um transformador toroidal?

Transformador toroidal is a major type of electronic transformador, which has been widely used in household appliances and other electronic equipment with high technical requirements. Its main purpose is as a power transformador and an isolation transformador. The Transformador toroidal has a complete series abroad and is widely used in computer, medical equipment, telecommunications, instruments and lighting. In the past ten years, the Transformador toroidal in China has grown from scratch. So far, it has formed a considerable production scale. In addition to meeting domestic demand, it also exports a large number of products. It is mainly used in audio equipment and automatic control equipment of household appliances and quartz lamp lighting in China.
Characteristics of Transformador toroidal
O núcleo com alta eficiência elétrica não possui entreferro e o fator de empilhamento pode chegar a 95%.
O ruído de vibração é pequeno. A ausência de entreferro no núcleo pode reduzir o ruído da vibração induzida do núcleo. O enrolamento envolve uniforme e firmemente o núcleo anular, reduzindo efetivamente o "zumbido" causado pela magnetostrição.
A temperatura de operação é baixa. Como a perda de ferro pode chegar a 1,1 w/kg, a perda de ferro é pequena, o aumento de temperatura do núcleo é baixo e o enrolamento tem boa dissipação de calor no núcleo com baixa temperatura, então o aumento de temperatura do transformador é baixo.
It is easy to install the Transformador toroidal. There is only one mounting screw in the center, so it is especially easy to install and disassemble quickly in electronic equipment.
Difference between Transformador toroidal and square transformador
Both the Transformador toroidal and the square transformador belong to the type of electronic transformador. From the appearance, the Transformador toroidal tem a forma de um anel. Seu núcleo é feito de chapas de aço silício, enquanto o núcleo do transformador quadrado é feito de chapas de aço silício tipo e e chapas de aço silício tipo I. Além das diferenças de aparência e estrutura, quais são as diferenças entre os dois?
1. Efficiency: under the same power, the working efficiency of 50W Transformador toroidal is 86% - 90%, while that of 50W square transformador is 80-84%.
2. Temperature rise: under the same power, the temperature rise of 50W Transformador toroidal is very low, while the temperature rise of 50W square transformador is high.
3. Cost: the Transformador toroidal above 200W has low cost, and the square transformador above 200W has high cost.
4. Interference: the magnetic leakage of the Transformador toroidal is very small, the magnetic leakage of the square transformador is obvious, and there is low-frequency interference.
5. Life: Although the Transformador toroidal and the square transformador have no obvious material of life decay, the life of the Transformador toroidal is longer than that of the square transformador.
6. Low temperature characteristics: the Transformador toroidal can be normally used in the environment of minus 30 degrees, which is very suitable for outdoor use in northern winter.
7. Flexible design: the volume of the Transformador toroidal can be flexibly customized according to the customer's requirements, and the multi winding can be customized according to the customer's requirements. No mold is required for customization, and the installation is convenient.
