Abstract

The invention provides a magnetism conduction sliding block power transformation device in a constant magnetic field, and belongs to the technical field of power transformation. The magnetism conduction sliding block power transformation device in the constant magnetic field mainly solves the problem that in the prior art, the eddy-current loss and the magnetic hysteresis loss caused by an alternating magnetic field to magnetism conduction matter are high. The magnetism conduction sliding block power transformation device comprises a magnetism conduction sliding block, a traction mechanism, an air gap, an induction coil, an exciting coil, an induction working magnetic circuit, a magnetism conduction bypass and a magnetic circuit, wherein the magnetism conduction sliding block is located in the air gap, and is driven by the traction mechanism to reciprocate in the air gap, the induction coil is wound around the induction working magnetic circuit, the exciting coil is wound around the magnetic circuit and is connected with a direct-current power source, the sectional area of the induction working magnetic circuit is equal to that of the magnetic circuit, the sectional area of the magnetism conduction bypass is equal to that of the magnetic circuit, the induction working magnetic circuit is connected with the two ends of the magnetism conduction bypass in parallel, an air gap end face is formed at one of the parallel ends, and the other parallel end is connected with the magnetic circuit. According to the magnetism conduction sliding block power transformation device in the constant magnetic field, the frequency of alternating current in the induction coil can be changed by changing the period of reciprocating motion of the magnetism conduction sliding block.

Description

technical field [0001] The invention belongs to the technical field of power transformation, and in particular relates to a constant magnetic field magnetic slider power transformation device. Background technique [0002] In the long-distance magnetic circuit transmission power system, the alternating magnetic field in the magnetic circuit produces large eddy current loss and hysteresis loss in the magnetic material, and the constant magnetic field has no eddy current loss and hysteresis loss. But a constant magnetic field cannot generate an electromotive force in a coil, nor does it generate a current in a closed circuit. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, to provide a constant magnetic field that limits the time-varying magnetic field within the induction coil, keeps the magnetic field in the magnetic circuit outside the induction coil unchanged, and greatly reduces eddy current los...
