Orthogonal iron core type controllable electric reactor with wedge-shaped groove and equivalent magnetic path length calculating method of orthogonal iron core type controllable electric reactor with wedge-shaped groove under direct-current magnetic bias

The invention discloses an orthogonal iron core type controllable electric reactor with a wedge-shaped groove and an equivalent magnetic path length calculating method of the orthogonal iron core type controllable electric reactor with the wedge-shaped groove under direct-current magnetic bias. The controllable electric reactor comprises a working iron core and a control iron core with the wedge-shaped groove. According to the controllable electric reactor and the equivalent magnetic path length calculating method, as the wedge-shaped groove is formed in the control iron core, the harmonic content output by the controllable electric reactor can be effectively reduced, the defect that a traditional electric reactor is high in harmonic content is overcome, and the working performance of the electric reactor is improved. Meanwhile, simulation software ANSOFT special for an electromagnetic field is adopted to calculating the alternating current equivalent magnetic path length, data of the magnetic induction intensity on a specific cross section in the orthogonal iron core type controllable electric reactor are derived and processed according to a studied algorithm, and the equivalent magnetic path length is accordingly calculated. By means of the method, errors, caused by unclear magnetization conditions of the internal iron cores, of calculation of the equivalent magnetic path length in a traditional method are reduced, the alternating current magnetization curve of the electric reactor has the higher scientificity accordingly, and guarantees are provided for studying the iron consumption and other characteristics of the orthogonal iron core type controllable electric reactor.
