Problems solved by technology

[0002] Three-phase core reactor, the three-phase characteristics are unbalanced due to the different length of the magnetic circuit
For hybrid core reactors, due to the difference in magnetic permeability between the core post and the iron yoke, the unbalance between the three phases is amplified, which will lead to poor circuit characteristics

Embodiment

[0010] Such as figure 1 and figure 2 As shown, a hybrid core reactor structure, which is arranged side by side by three identical single-phase reactors 1 equidistant; the single-phase reactor 1 is a hybrid core structure, which includes a core column 2; the core column 2 Iron yokes 3 are arranged at the upper and lower ends; clamping plates 4 are arranged at the front and rear sides of the core column 2 .

[0011] A hybrid core reactor structure in this embodiment, the three-phase reactor is decomposed into three single-phase reactors, each single-phase reactor adopts a hybrid core structure, and a certain distance is kept between the cores to avoid the generation of a magnetic field between the three phases Interference; that is, it ensures the excellent characteristics of the hybrid core reactor, and also makes the length of the magnetic circuit between the three phases equal, which greatly reduces the three-phase unbalance.

Abstract

The invention relates to a mixed core reactor structure. The mixed core reactor structure is formed by arranging three same single-phase reactors at equal distances side by side, wherein each single-phase reactor is in a mixed core structure and comprises a core column; yokes are arranged at the upper end and the lower end of each core column; and clamping plates are arranged at the front side and the back side of each core column. By the mixed core reactor structure, a three-phase reactor is decomposed into the three single-phase reactors; the mixed core structure is adopted by each single-phase reactor; and a certain distance is kept between the cores to avoid magnetic-field interference generated among three phases, so that excellent characteristics of the mixed core reactor are ensured; magnetic circuits among the three phases are equal in length; and the three-phase imbalance degree is greatly reduced.

Description

technical field [0001] The invention relates to the field of reactors, in particular to a hybrid core reactor structure. Background technique [0002] For three-phase core reactors, the three-phase characteristics are unbalanced due to the difference in the length of the magnetic circuit. For the hybrid iron core reactor, due to the difference in magnetic permeability between the core post and the iron yoke, the unbalance between the three phases is amplified, which will lead to the deterioration of the circuit characteristics. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a hybrid core reactor structure. [0004] The technical solution adopted by the present invention to solve the technical problem is: a hybrid core reactor structure, which is arranged side by side with three identical single-phase reactors equidistant; the single-phase reactor is a hybrid core structure, which includes a core a column;...
