The structure of transformer iron cores mainly includes core type and shell type. Core-type iron cores have windings surrounding the core columns, with a relatively simple structure, convenient manufacturing, and good heat dissipation performance. Most power transformers adopt this structure. Core-type iron cores usually consist of core columns, yokes, and clamping devices. The core columns are the main parts through which magnetic flux passes, and the yokes are used to connect the core columns to form a closed magnetic circuit. Shell-type iron cores have the iron core surrounding the windings, with high mechanical strength and strong short-circuit resistance, but the structure is relatively complex and manufacturing is difficult, and they are mostly used in special transformers and small transformers. In addition, according to the number of core columns, they can also be divided into single-phase iron cores and three-phase iron cores. Single-phase iron cores are used in single-phase transformers, consisting of two core columns and upper and lower yokes; three-phase iron cores are used in three-phase transformers, with common structures such as three-phase three-column and three-phase five-column.
