A structure that suppresses magnetic flux leakage and improves transmission efficiency of alternating magnetic field

Abstract

The invention discloses a structure for suppressing magnetic flux leakage and improving the transmission efficiency of an alternating magnetic field. Based on the overall structure of a transformer or a transformer, the structure of a magnetic energy transmission device made with this structure is as follows: a primary coil (2) is wound around an iron core (1 ) and connected to the AC power supply through the primary coil joint (3); the secondary coil (5) is wound on the other end of the iron core (1) and connected to the load through an external lead (7). The part of the iron core (1) not covered by the coil has a superconductor-ferromagnet heterostructure shielding layer (4) formed by alternately winding superconducting layers (401) and ferromagnetic layers (402). The invention can effectively suppress the magnetic flux leakage problem of the iron core of the traditional transformer, improve the transmission efficiency of the transformer, and simultaneously improve the measurement accuracy of the current (voltage) transformer.

technical field [0001] The invention proposes a structure for suppressing magnetic flux leakage and improving the transmission efficiency of an alternating magnetic field, and relates to the fields of electric energy conversion such as transformers and transformers. Background technique [0002] The magnetic field plays a pivotal role in the scientific and technological life of human beings, and the effective utilization and transmission of magnetic energy has always been the focus of research in the scientific and technological circles. The transformer works on the principle of electromagnetic induction, when an AC voltage U is applied to the primary side of the transformer 1 , the current flowing through the primary winding is I 1 , then the current will generate alternating magnetic flux in the iron core. By connecting the iron cores of the primary side and the secondary side, the primary winding and the secondary winding will be electromagnetically correlated, and the m...

Problems solved by technology

Traditional iron cores are generally made of high-permeability electrical materials through a certain process, and their electromagnetic properties are basically isotropic. It is difficult to constrain the magnetic flux lines to the transmission direction, which in turn causes magnetic flux leakage, resulting in A lot of magnetic energy is dissipated
