Embodiment Construction

[0027] In order to better understand the present invention, the technical scheme of the present invention will be further described below in conjunction with embodiment and accompanying drawing (as Figure 1-9 shown).

[0028] An inductance balance magnetic core of a three-phase reactor, mainly composed of an upper yoke part 1, a lower yoke part 2 and three magnetic columns 3 in a horizontal "day"-shaped magnetic core; the upper yoke part 1, the lower yoke part 2 and the magnetic column 3 are formed by stacking several magnetic blocks 6. The magnetic column 3 is vertically divided into multiple layers, and each layer is arranged in a rectangular array with a plurality of magnetic blocks 6. The upper yoke 1 and the lower yoke The yoke 2 is provided with three groups of magnetic blocks along the length direction, and the three groups of magnetic blocks are respectively located on the corresponding three magnetic columns 3; each group of magnetic blocks includes vertical multi-la...

Abstract

The invention relates to the technical field of reactors, in particular to an inductance balance magnetic core of a three-phase reactor and a three-phase reactor. The inductive balance magnetic core of the three-phase reactor is mainly composed of a magnetic core shaped like a Chinese character 'ri', which is composed of an upper yoke part, a lower yoke part and three magnetic columns. Air gap gaskets are arranged between the middle magnetic column and the upper yoke part and lower yoke part. The magnetic core avoids a coil by arranging the air gaps at the upper and lower ends of the magneticcolumn, so that when the inductance of three groups of coils reaches the equilibrium state, no diffusion flux phenomenon occurs, and no eddy current loss is caused to the coil, thus the local temperature of the coil is not raised. The reactor is used to solve the problem of reduction of the service life of the reactor because the coil temperature at the air gaps of the reactor magnetic core is toohigh.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to an inductance balance magnetic core of a three-phase reactor and a three-phase reactor. Background technique [0002] A reactor is also called an inductor. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all electrical conductors that can carry current have inductance in the general sense. However, the inductance of the energized long straight conductor is small, and the magnetic field generated is not strong, so the actual reactor is in the form of a solenoid wound with wires, which is called an air-core reactor; sometimes in order to make the solenoid have a larger inductance, Then insert the magnetic core in the solenoid. Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductors (inductors) and capacitive reactances (capacitors) are collectively referred to ...
