Description

Power transformer

Technical Field

The utility model relates to the technical field of transformers, in particular to a power transformer.

Background

For a small power transformer, an iron core is an important component, and is not only a magnetic flux loop of the transformer, but also can be used as a supporting core of the transformer, and in the design of the small power transformer, how the section of an iron core column is designed is an important link;

the publication No. CN202816578U discloses a middle-size and small-size power transformer iron core column, including 21 grades of silicon steel sheets that stack in proper order, the cross-section of every grade of silicon steel sheet is the rectangle, and the heart post overall cross-section becomes multistage ladder-shaped, and the cross-section of each grade of silicon steel sheet is in the circle of circumscribed of iron core column all axisymmetry about, and the circle diameter of circumscribed of its iron core column is 380 millimeters. The middle-small power transformer core column has the advantages of strong practicability, better effective sectional area, higher utilization rate of the section, better energy-saving effect, lower total cost, more energy loss reduction and the like;

the iron core column in the existing power transformer adopts a stacking mode to arrange, the design is complex, the cost of the iron core column is high, sales profits are reduced, meanwhile, heat accumulated by winding coils is difficult to dissipate, the temperature during working is high, the service life of the power transformer is easy to reduce after long-term use, and therefore the power transformer is provided.
