The stacked laminations are assembled and clamped together using mechanical pressure to ensure firm contact and minimize gaps between the laminations.
In some cases, the assembled core may undergo a process of vacuum impregnation with varnish or resin to further enhance mechanical strength and insulation properties.
Core Testing: After assembly, the core undergoes rigorous testing to verify its magnetic properties, such as magnetic flux density, core losses, and other performance parameters. This ensures that the core meets the efficiency and reliability requirements specified for the transformer.
Final Processing: Once the core assembly and testing are completed, the core may undergo additional processing steps such as cutting or punching holes for winding coils, as well as final coating or painting for protection against environmental factors.
Importance of Core Assembly
Efficiency: Proper assembly ensures minimal energy losses (core losses) due to hysteresis and eddy currents, contributing to the overall efficiency of the transformer.
Reliability: A well-assembled core provides mechanical strength and stability, reducing the risk of mechanical failure during operation.
Performance: The magnetic properties of the core directly affect the transformer's performance in terms of voltage regulation, load capacity, and overall electrical characteristics.
Core assembly in CRGO transformers requires precision and adherence to standards to achieve optimal performance and reliability. We often employ specialized equipment and quality control measures to ensure that each core meets stringent requirements for electrical and mechanical performance.
