Single-phase two-column laminated core
The core sheets are stacked in an overlapping manner, and the two columns are covered with coils, which are led out by series and parallel connecting lines. The structure is simple and compact, with less process equipment, but the stacking workload is large. It is a widely used single-phase core basic structure.
Applicable to various single-phase transformers
Single-phase single-column side yoke laminated core
There is a core column in the middle and side yokes on both sides. The cross section of the yoke is 1/2 of the cross section of the core column. It can reduce the height of the upper and lower yokes, which helps to reduce additional losses, but the amount of electrical steel sheets used is large. It is actually a single-phase shell core placed vertically.
suitable for high-voltage, large-capacity, single-phase power transformers or high-current single-phase transformers.
Single-phase two-column side yoke laminated core
There are two core columns in the middle and side yokes on both sides, which can reduce the height of the upper and lower yokes and help reduce additional losses, but the amount of electrical steel sheets used is more and the volume is larger. Sometimes the voltage regulating and excitation coils are installed on the side yokes. It is a derivative structure of.
Suitable for high-voltage and ultra-high-voltage large-capacity single-phase power transformers.
Three-phase three-column laminated core
The structure is the same as the single-phase two-column stacked core, except that there is one more core column, and the three-column coils are each led out for one phase. It is the most widely used typical structure of three-phase transformers.
