Technical Field

Background
Along with the rapid development of modern technology, the application of products related to reactance induction is more and more widespread, and a three-phase reactor is common electrical equipment in a power system and is used for providing resistive and inductive loads on alternating current and playing roles in reactive compensation, filtering, current limiting and the like. However, in practical application, we often encounter the problem of unbalanced inductance of three phases.
The cause of the imbalance of the inductance of the three-phase reactor is generally various. First, variations in the number of turns of the wire during manufacture can lead to inconsistent three-phase inductance values and different turns per phase in the opposite side wire-out mode required in some particular locations. For example, when winding a coil, there is a certain error in the number of turns per phase when the number of turns is large, resulting in unbalanced inductance, due to equipment accuracy problems. Secondly, material non-uniformity is also a cause of inductance imbalance, such as cutting tolerances, material permeability deviations, manufacturing accuracy deficiencies, etc.
Particularly, when a contralateral wire outlet mode is adopted, the inductance balance degree of the three phases cannot be ensured under the condition that the number of turns of the A phase or the C phase is one turn more, and the method is particularly obvious when the number of turns is small. The conventional method cannot solve the problem, or adjusts the balance of the inductor by a corresponding method of increasing or decreasing the number of turns, but the method brings about the problem of unbalanced three-phase resistance.

The utility model adopts a special solution that amorphous alloy or silicon steel sheet and iron silicon are matched for use. The ferrosilicon material has the characteristics of low magnetic permeability and multiple specifications and can generate different inductance values by using ferrosilicon with different specifications under the same volume. The distributed air gap is the tiny gap or void existing in the ferro-silicon material. These air gaps are typically caused by gases or impurities inside the material. Amorphous alloys and silicon steel sheets require an addition of an air gap separately from the material due to their high magnetic permeability and the absence of distributed air gaps. The inductance is higher than the standard and the air gap is required to be increased to reduce the inductance, and the inductance is lower than the standard and the air gap is required to be reduced to increase the inductance, but when the three-phase inductance is very unbalanced, the air gap height of each phase is inconsistent, so that the upper yoke of the iron core cannot be folded due to inconsistent core column heights. In order to solve such inconsistency, the application of the iron silicon material is added to the phase column with high inductance, the inductance value of the phase can be reduced while the height consistency of the core column is ensured, and therefore the three-phase inductance balance is ensured, and the three-phase resistance imbalance is not caused.

The iron core column is mainly adjusted to be the proportion of the middle iron silicon and the iron-based amorphous of the two columns A and B, the phase A is one turn more due to the fact that the outgoing lines are formed at the two sides, and the phase B is higher due to the fact that the magnetic circuit is short, so that through calculation, the iron core column 10 adopts 13 core columns, 5 iron silicon blocks, 8 iron-based amorphous blocks, the core column 11 13 core columns, 1 iron silicon block, 12 iron-based amorphous blocks, epoxy glue is coated on the side faces, the glue penetrates into the core column, and the core column is clamped by a clamp, so that the iron core column is bonded and solidified into a whole.

The prepared iron core columns are placed according to the requirements (as shown in figure 1), then the coil 5 is sleeved into the iron core, the upper iron yoke 9, the lower iron yoke 9 and the iron core columns are locked by bolts and nuts 3 (as shown in figure 2), and the inductance of the three-phase reactor is balanced through the proportion of the upper iron core columns.
The beneficial effects of the utility model are as follows: the amorphous alloy or silicon steel sheet and the iron-silicon are adopted to be matched with each other for use, the three-phase iron core comprises a three-phase iron core main body, the iron core main body comprises an iron yoke and an iron core column, the iron yoke is an iron-based amorphous iron yoke, the iron core column is an iron-silicon and iron-based amorphous core column, and the inductance balance of the three-phase reactor is achieved through the quantity adjustment ratio of the iron-silicon core column and the iron-based amorphous core column in the A core column 10 and the B core column 11 in the three-phase iron core column.
