Single-Phase Transformer: Structural Comparison & Safety Insights

Two primary internal designs exist for single-phase transformers:

1. Two Coils, One Core: Separate primary and secondary windings share a unified laminated iron core, ensuring efficient magnetic coupling and minimal leakage flux.

2. One Coil, Two Cores: A single winding splits across two independent cores, complicating magnetic pathways and increasing flux dispersion.

In China, the two-coils-one-core design dominates due to its manufacturing simplicity, cost efficiency, and alignment with domestic grid standards. Comparative studies reveal its superior safety:

• Lower operating temperatures (reduced by 15-20% under load)

• Higher short-circuit resilience (30% lower failure risk)

• Enhanced insulation durability (prolonged lifespan by 25%)

Experimental data consistently validates that the two-coils-one-core configuration ensures safer, more stable performance, making it the preferred choice for industrial and residential applications.
