Abstract

The invention discloses a linear iron core-closed power reactor, which adopts a closed iron core structure, wherein an iron core is formed by uniformly mixing a ferrous powder material and a non-magnetic conducting material, the closed iron core structure is formed by integral pouring, and a winding is wound on an iron core column. The linear iron core-closed power reactor solves the problems of unstable inductance of the conventional gapped iron core reactor, and large volume of the conventional hollow reactor.

Description

Linear iron core-closed power reactor
Technical field
The present invention relates to a kind of power reactor, the linear iron core-closed power reactor that particularly a kind of volume is little, iron core is closed, inductance value is constant.
Background technology
Power reactor is widely used in the electric power system, and its effect mainly is following several respects: the one, and the short circuit current of restriction system, the 2nd, the capacitance current of bucking-out system, the 3rd, be used for the tuning and flat ripple of direct current of filtering.At modern power systems and is in the industrial production of main energy sources with electric power because the continuous increase of place capacity, cause need be bigger inductance, reach the purpose of control capacitive reactive power.At present, power reactor extensively adopts iron core reactor and two kinds of versions of air core reactor of band air gap, the iron core reactor of band air gap is owing to have permeability magnetic material in the magnetic circuit, compare with the air core reactor of same electrical sensibility reciprocal, volume is less, but the inductance value of the iron core reactor of band air gap can change with the size of conducting electric current, and inductance value is non-constant; Air core reactor is owing to being magnetic conductive media with the air, and inductance value does not change with the size variation of conducting electric current, and therefore, filter reactor adopts air core reactor more, but volume is bigger, for the limited industrial enterprise in space, has limited range of application.
Summary of the invention
In order to solve the easily saturated and bulky technical problem of air core reactor of existing band air-gap iron core reactor, the invention provides that a kind of volume is little, the linear iron core-closed power reactor of anti-saturation.
The technical solution adopted for the present invention to solve the technical problems is: reactor adopts closed type structure unshakable in one's determination, and its iron core adopts iron powder material evenly to mix with non-magnet material, and by the iron core-closed structure of integrated poured formation, again coiling winding on iron core column.
In the above-mentioned linear iron core-closed power reactor, the core structure of described reactor is any of annular, square shape or three pillar type structure.
Technique effect of the present invention is: the present invention adopts iron powder other material that mixes, mix according to certain mass ratio, make unsaturated permeability magnetic material based on iron powder, and this unsaturated permeability magnetic material is processed into the iron powder stem stem, and at iron powder stem stem coiling winding formation linear iron core-closed power reactor, this ferrocart core power reactor keeps inductance constant in current margin, make the U-I characteristic of reactor keep linear, and, reduced the eddy current in the ferrocart core greatly owing in iron powder, add non-magnet material; The iron core of reactor adopts integral pouring procedure, can greatly reduce the reactor vibration and noise, reduces the noise pollution to environment.
The present invention is further illustrated below in conjunction with accompanying drawing.

Embodiment
Referring to Fig. 1, Fig. 1 is the structural representation of the embodiment of the invention 1.Single-phase linear iron core-closed power reactor as shown in Figure 1 is the loop configuration pattern, and winding 2 is wound on the iron core 1 that is made of iron powder and non-magnet material.
Referring to Fig. 2, Fig. 2 is the structural representation of the embodiment of the invention 2.Single-phase linear iron core-closed power reactor as shown in Figure 2 is the square shape structural shape, and winding 2 is divided into two sections and is wound on respectively on two stems, iron core 1 closure, and the windings in series on two stems constitutes same winding together.
Referring to Fig. 3, Fig. 1 is the structural representation of the embodiment of the invention 3.Three-phase linear iron core-closed power reactor as shown in Figure 3 adopts the three pillar type structural shape, 2.A phase winding, the 3.B phase winding, 4.C phase winding A/B/C three phase windings are wound on respectively on three stems, iron core 1 closure constitutes three single-phase linear iron core-closed power reactors.
With the main material of iron powder as the iron core of reactor, add a spot of silicon and aluminium again among the present invention, the shared percentage by weight of iron sial is respectively 85%, 9% and 6%, adds the epoxy resin of 0.05wt% again, is mixed by blender; Mixed iron powder and epoxy resin are put into mould compression moulding, coil again.
