Embodiment Construction
[0012] Reference figure 1 - figure 2 A three-dimensional wound core photovoltaic transformer with stable windings of the present invention includes a three-dimensional wound core 1 with symmetrical three-phase magnetic circuits, and three-phase windings 2 arranged on the three-dimensional wound core 1 in a three-dimensional triangular distribution. Each single-phase winding 3 of the three-phase winding 2 includes a primary winding 4 and a secondary winding 5, and each single-phase winding 3 also includes a stable winding 6, which is arranged between the secondary winding 5 and the iron core. The two stable windings 6 are connected to each other to form a stable winding triangular connection structure, and an electrostatic screen 7 is provided between the primary winding 4 and the secondary winding 5. The structure of the single-phase winding 3 from the inside to the outside is as follows: iron core-stable winding 6-secondary winding 5-electrostatic screen 7-primary winding 4. ...
