定义
The isolation transformer core is the central magnetic component constructed from laminated silicon steel sheets that provides the magnetic flux path for energy transfer between primary and secondary windings while preventing direct electrical connection, ensuring safety and noise reduction in electrical systems.
工作原理
Operates on electromagnetic induction principles where alternating current in the primary winding creates a varying magnetic flux in the core, which induces voltage in the secondary winding while maintaining complete electrical isolation between circuits through dielectric insulation.

Core Loss
1.2-2.5 W/kg at 1.5T, 50Hz
Core Type
EI, UI, or Toroidal
Flux Density
1.5-1.7 Tesla
Material Grade
M4-M6 Silicon Steel
Stacking Factor
0.95-0.97
Insulation Class
Class B, F, or H
Lamination Thickness
0.23-0.35mm
Operating Temperature
-40°C to 155°C
标准
ISO 9001IEC 61558UL 506DIN EN 61558

常见问题

What is the primary function of an isolation transformer core?

To provide a magnetic path for energy transfer while maintaining complete electrical isolation between primary and secondary circuits for safety and noise reduction.

Why are silicon steel laminations used instead of solid metal?

Laminated construction reduces eddy current losses by interrupting current paths, improving efficiency and reducing heat generation in the transformer.

What are the main differences between EI and toroidal core designs?

EI cores offer easier manufacturing and lower cost, while toroidal cores provide better magnetic efficiency, lower electromagnetic interference, and more compact designs.
