Magnetic integrated hybrid distribution transformer

A magnetic integrated hybrid distribution transformer, comprising an iron core, windings and a converter (22), wherein:

• the iron core comprises an iron beam unit, an iron yoke unit and a leakage magnetic core unit;
• the iron beam unit comprises three main transformer iron beams and three isolation transformer iron beams that connect with each other sequentially;
• the iron yoke unit comprises a bottom iron yoke (17), a middle iron yoke (16) and four connection iron yokes;
• the leakage magnetic core unit comprises four control winding leakage magnetic cores and three converter side winding leakage magnetic cores;
• the windings comprise main transformer windings and series isolation transformer windings;
• in each phase, the main transformer windings are a control winding, a primary winding and a secondary winding all of which are wrapped around a corresponding main transformer iron beam;
• in each phase, the series isolation transformer windings are a grid side winding and a converter winding both of which are wrapped around a corresponding isolation transformer iron beam;
• each main transformer iron beam connects to the bottom iron yoke (17) and the middle iron yoke (16);
• each connection iron yoke connects to the middle iron yoke (16) and an end of the corresponding series isolation transformer iron beam;
• the main transformer iron beams and the isolation transformer iron beams form two main transformer windows and three series isolation transformer windows by sharing the middle iron yoke (16);
• the control winding leakage magnetic cores are respectively inserted between primary windings and control windings within two main transformer windows;
• the converter side winding leakage magnetic cores are respectively inserted between converter side windings and grid side windings within the three series isolation transformer windows;
• the converter (22) connects to the control windings and converter side windings.
