Abstract

The invention discloses an isolation type transformer winding. The winding comprises a framework, a primary side winding, a secondary side winding and a secondary side Y winding, wherein the primary side winding is wound on the framework, the primary side winding is equally divided into two layers of windings, the secondary side winding and the secondary side Y winding are sequentially wound between the two layers of windings, the primary side winding is evenly distributed on two sides of the secondary side winding, one layer of windings of the primary side windings is wound on an innermost layer of the framework, and the other layer of windings of the primary side winding is wound on an outermost layer of the secondary side Y winding. A sandwich winding method is adopted, so a magnetic field generated by the primary winding can be fully utilized, leakage inductance of the transformer is reduced, an output voltage is not lower than the output voltage when the transformer is in full load work, the range of the direct-current output voltage of a transformer product is reduced, and popularization and application of the transformer winding structure are facilitated.

Description

technical field [0001] The invention relates to the technical field of aviation power conversion, in particular to an isolated transformer winding. Background technique [0002] With the development of aviation conversion power supply technology, the quality requirements for the conversion power supply are getting higher and higher; in large-scale electrochemical or electrometallurgical or aviation conversion power supply DC power supply systems, the same-phase anti-parallel 12-pulse rectifier unit is composed of 24 phases , 36-phase, 48-phase rectification system basic unit, now using 12-pulse isolation transformer as AC / DC conversion power supply. [0003] However, the existing 12-pulse isolation transformer has a large output DC voltage range, the magnetic field generated by the transformer winding cannot be fully utilized, and the leakage inductance of the transformer is large, which is difficult to meet the needs of aviation power conversion.
