Analysis of Advantages and Solutions for Single-Phase Distribution Transformers Compared to Traditional Transformers
1. Structural Principles and Efficiency Advantages1.1 Structural Differences Affecting EfficiencySingle-phase distribution transformers and three-phase transformers exhibit significant structural differences. Single-phase transformers typically adopt an E-type or wound core structure, while three-phase transformers use a three-phase core or group structure. This structural variation directly impacts efficiency: The wound core in single-phase transformers optimizes magnetic flux distribution, red
