Abstract
The invention relates to an iron core convenient to manufacture and install for a three-phase inductor. The iron core comprises a lower cross yoke, a first side post and a second side post, wherein the first side post and the second side post are arranged on the lower cross yoke, the tops of the first side post and the second side post are jointly connected with an upper cross yoke, the lower cross yoke, the upper cross yoke, the first side post and the second side post jointly encircle a closed space, a first intermediate post, a second intermediate post and a third intermediate post which have same structure are arranged in the space, air gaps are formed among the first intermediate post, the second intermediate post, the third intermediate post and the upper cross yoke, and the upper cross yoke is in an inverted concave shape. By forming air gaps among the first intermediate post, the second intermediate post, the third intermediate post and the upper cross yoke, the iron core is used for adjusting an inductance value and preventing magnetic saturation; and the inverted concave-shaped upper cross yoke is reversely used, thus, the sizes of the air gaps are changed, and two types of magnetic conductivity can be achieved by one-time mold opening of the iron core.
Description
Technical field
The present invention relates to charging technique field, specifically a kind of three pole reactor iron core being convenient to making and installation.
Background technology
In work frequency circuit, three pole reactor is a kind of conventional element, comprises various iron core material, three-phase three-column, three-phase and five-pole etc. shape.But ubiquity problem: owing to installing fastening mode problem, causes that magnetic is close can not be maximized, and generally designs 1.2-1.5T, otherwise noise is serious, loss is very large, and therefore, the general volume of iron core is comparatively large, is not easy to install.
Therefore, be necessary to provide a kind of novel three pole reactor iron core being convenient to making and installation to solve the problems referred to above.
Summary of the invention
The object of this invention is to provide a kind of three pole reactor iron core being convenient to making and installation of registration.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of three pole reactor iron core being convenient to making and installation, comprise bottom rail yoke, be positioned at the first lateral column on described bottom rail yoke and the second lateral column, the top of described first lateral column and described second lateral column is connected with horizontal yoke jointly, described bottom rail yoke, described horizontal yoke, described first lateral column, described second lateral column surrounds a closed space jointly, the first center pillar that three structures are identical is provided with in this space, second center pillar, 3rd center pillar, described first center pillar, second center pillar, air gap is formed between 3rd center pillar and described horizontal yoke, described horizontal yoke is inverted concave character type.
Further, described bottom rail yoke is parallel with described horizontal yoke, and described first lateral column is parallel with the second lateral column, and described first lateral column, described second lateral column are all vertical with described bottom rail yoke,
Further, described first center pillar is positioned on the vertical center line of described iron core, the both sides being positioned at described first center pillar that described second center pillar, described 3rd center pillar are symmetrical respectively, described first center pillar, described second center pillar, described 3rd center pillar are all parallel with described first lateral column.
Further, the end face of described first center pillar, described second center pillar, described 3rd center pillar is all lower than the end face of described first lateral column and described second lateral column.
Further, the side of described bottom rail yoke is provided with two symmetrical installing ports.
Further, connected by argon arc welding between each parts of described iron core.
Compared with prior art, the beneficial effect that the three pole reactor iron core of making and installation is convenient in the present invention is: by the first center pillar, the second center pillar, form air gap between the 3rd center pillar and described horizontal yoke, for adjusting inductance value and preventing magnetic saturation, by the positive and negative use of upper horizontal yoke by concave character type, change the size of air gap, make a die sinking iron core can obtain two kinds of magnetic permeabilitys.
Accompanying drawing explanation
Fig. 1 is the structural representation that the three pole reactor iron core of making and installation is convenient in the present invention.
Embodiment
Refer to Fig. 1, a kind of three pole reactor iron core being convenient to making and installation, comprise bottom rail yoke 1, be positioned at the first lateral column 3 and the second lateral column 4 on bottom rail yoke 1, first lateral column 3 is connected with the top of bottom rail yoke 1 with the bottom of the second lateral column 4, the top of the first lateral column 3 and the second lateral column 4 is connected with horizontal yoke 2 jointly, bottom rail yoke 1 is parallel with upper horizontal yoke 2, first lateral column 3 is parallel with the second lateral column 4, first lateral column 3, second lateral column 4 is all vertical with bottom rail yoke 1, bottom rail yoke 1, upper horizontal yoke 2, first lateral column, second lateral column surrounds a closed space jointly, the first center pillar 5 that three structures are identical is provided with in this space, second center pillar 6, 3rd center pillar 7, first center pillar is positioned on the vertical center line of whole iron core, second center pillar 6, the both sides being positioned at the first center pillar 5 that 3rd center pillar 7 is symmetrical respectively, first center pillar 5, second center pillar 6, 3rd center pillar 7 is all parallel with the first lateral column 3.
The end face of the first center pillar 5, second center pillar 6, the 3rd center pillar 7 all lower than the end face of the first lateral column 3 and the second lateral column 4, thus and forms air gap 8 between upper horizontal yoke 2, for adjusting inductance value and preventing magnetic saturation.
Upper horizontal yoke 2 is inverted concave character type, and it has recess 9, when needs change iron core magnetic conductance, by upper horizontal yoke 2 is upwards overturn 180 °, make recess 9 upward, now the size of air gap 8 changes, and makes a die sinking iron core can obtain two kinds of magnetic permeabilitys by yoke 2 horizontal in positive and negative use.
The side of bottom rail yoke 1 is provided with two symmetrical installing ports 10, can pass through installing port 10, is fixed on installed surface by iron core easily with small-sized pressing plate.The shape of installing port 10 comprises square, circular etc.
Fixed by argon arc welding between each parts of whole iron core, and argon arc welding position is outside main magnetic circuit, eddy current loss is little, can to design higher magnetic close, according to material can >=2T, reduce iron core consumption with it, reduce finished weight.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
