Research on no-load loss of Nanocrystalline Iron Core Transformer

After testing the loss curve of the nanocrystalline iron core, a transformer loss coefficient iron loss calculation model was obtained based on the measured data. The no-load losses of nanocrystalline iron core transformers and silicon steel sheet iron core transformers under sinusoidal voltage source excitation were compared and analyzed, and the following conclusions were drawn:

Taking SCB12-L-800/10 transformer as an example, the no-load losses of the transformer at different frequencies were analyzed, calculated, and simulated for comparison. The results showed that the transformer coefficient iron loss calculation model can improve the accuracy of iron loss calculation.

2. Using SCB12-L-800/10 transformer as a model, finite element analysis is conducted on the iron loss of nanocrystalline iron core transformers and traditional silicon steel sheet iron core transformers. Under the same conditions, the iron loss of nanocrystalline iron core transformers is reduced by 90.5% compared to traditional silicon steel sheet transformers

3. The magnetization performance of nanocrystalline iron cores is superior, with high saturation magnetic density and high magnetic permeability, which can effectively reduce iron core losses during transformer operation, avoid transformer component heating caused by increased leakage magnetic flux, effectively reduce transformer volume and weight, improve transformer efficiency, and achieve the goal of high efficiency, green energy conservation.
