Abstract
The invention discloses a core column structure for an iron core electric reactor. The core column structure comprises an iron core column and core penetrating screw rods, wherein the iron core column comprises a plurality of core columns axially arranged in sequence and an air gap between every two adjacent core columns; pull plates are arranged on the two sides of the iron core column; the core penetrating screw rods penetrate through the core columns and are fixed to the core columns through fasteners; and the fasteners are locking nuts. According to the core column structure for the iron core electric reactor, the core penetrating screw rods are additionally arranged in the core columns of the iron core column, so that the vibration of the core columns is limited, the noise of the iron core electric reactor can be remarkably reduced, the safety problem caused by the vibration of the core columns is avoided, and the core columns are more firmly contacted with the pull plates.
Description
Technical field
The present invention relates to a kind of stem structure, relate in particular to a kind of stem structure that is used for iron-core reactor.
Background technology
At present, reactor is widely used in electric power system and makees reactive-load compensation equipment, and reactor roughly is divided into three kinds according to the form of iron core: a kind of is air core reactor, and this reactor has only winding and do not have iron core, is exactly in fact a hollow inductance coil; Another kind is an iron-core reactor, and its magnetic circuit is the core limb of a closure, and the core limb outside is with winding; Also have a kind of be the band air gap iron-core reactor, its structure as shown in Figure 1, its magnetic circuit be one the band air gap core limb, the core limb outside is with winding.
The iron core that wherein has high magnetic permeability with the iron-core reactor of air gap, therefore inductance value is bigger, volume is less, and the air gap that is provided with in the core limb makes the inductance value of reactor not change with the change of the electric current by reactor basically, therefore the inductance value with the iron-core reactor of air gap is big and stable, can also change the inductance value of the iron-core reactor of band air gap by the height of regulating air gap between the stem, so the range of application of the iron-core reactor of band air gap is wider, but this iron-core reactor is owing to exist air gap in its core limb, each section stem can and the space bar of air gap between can produce very big electromagnetic force, thereby make core limb produce bigger vibration and noise, also be easy to generate the part to thermal phenomenon, bring unsafe hidden danger for the operation of iron-core reactor.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: proposed a kind of iron-core reactor motive rod structure of avoiding core limb to produce vibration and noise.
Technical solution of the present invention is achieved in that a kind of iron-core reactor rod structure diligently, comprise core limb and core through screw rod, described core limb is made of the air gap that is provided with between several stems that are arranged in order along its axis and every adjacent two stems, and described core limb both sides are provided with arm-tie; Described core through screw rod passes stem, and is fixed on the stem by securing member.
Preferably, described securing member is a locking nut.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
A kind of iron-core reactor of the present invention program is rod structure diligently, by in every section stem of core limb, increasing core through screw rod, so just limited the vibration of each stem, can significantly reduce the noise of iron-core reactor, avoided the safety problem brought by stem vibration, and make between stem and the arm-tie contact more firm.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the iron-core reactor motive rod structure of prior art;
Accompanying drawing 2 is the iron-core reactor of the present invention structural representation of rod structure diligently;
Wherein: 1, core limb; 2, stem; 3, air gap; 4, arm-tie; 5, core through screw rod; 6, locking nut.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of iron-core reactor as shown in Figure 2 is rod structure diligently, comprise core limb 1 and core through screw rod 5, described core limb 1 is made of the air gap 3 that is provided with between several stems 2 that are arranged in order along its axis and every adjacent two stems, and described core limb 1 both sides are provided with arm-tie 4; Described core through screw rod 5 passes stem 2, and is fixed on the stem 2 by securing member; Described securing member is a locking nut 6.
A kind of iron-core reactor of the present invention program is rod structure diligently, by in every section stem 2 of core limb 1, all increasing core through screw rod 5, iron-core reactor is when making like this, core through screw rod 5 has limited the vibration of each stem 2, therefore can reduce the noise of iron-core reactor significantly, avoided the safety problem brought by stem 2 vibration, and make between stem 2 and the arm-tie 4 contact more firm.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
