Abstract

The utility model relates to the technical field of electric reactors, and discloses a three-dimensional triangular dry type electric reactor which comprises an iron core. An insulation layer is arranged on the outer wall of the iron core, a coil is wound on the outer wall of the insulation layer, an upper cushion block and a lower cushion block are arranged at the two ends of the iron core respectively, an upper iron yoke is arranged on the upper cushion block and sleeved with an upper clamp, a lower iron yoke is arranged on the lower cushion block and sleeved with a lower clamp, the lower clamp is provided with a cushion foot, and the lower clamp and the cushion foot are fastened through a bolt. The three-dimensional triangular dry type electric reactor is characterized in that the iron core is composed of three iron core columns, each iron core column is of a cylindrical structure formed by stacking a plurality of iron core cakes, and air gap plates are clamped between adjacent iron core cakes. The three-dimensional triangular dry type electric reactor has the advantages that wire winding is convenient, and hysteresis loss and eddy-current loss are small.

Description

A kind of 3-D triangle dry reactor

Technical field

The utility model relates to reactor technical field, particularly relates to a kind of 3-D triangle dry reactor.

Background technology

As everyone knows, reactor is also inductor, when a conductor energising, will produce magnetic field in its occupied certain space scope, so the electric conductor of all energy current-carrying has perception in general sense.But the inductance of the long straight conductor of energising is less, the magnetic field producing is not strong, and therefore actual reactor is that wire is coiled into solenoid form, claims air core reactor; Sometimes in order to allow this solenoid there is larger inductance, just in solenoid, insert iron core, claim iron-core reactor.Reactance is divided into induction reactance and capacitive reactance, relatively the classification of science is that impedor (inductor) and capacitive reactance device (capacitor) are referred to as reactor, but because first there has been inductor in the past, and be called as reactor, so the said capacitor of people is exactly capacitive reactance device now, and reactor specially refers to inductor, the reactor in present specification is inductor.

At present, 3-D triangle dry reactor is the one in reactor, the iron core of existing 3-D triangle dry reactor is repeatedly to make frame type structure by silicon steel sheet mostly, find by long-term use link, there is following defect in the 3-D triangle dry reactor of said structure: while wanting suit coil due to the iron core of above-mentioned frame type structure, first iron core to be healed up and opens, then suit coil, finally again healing up to closure, because amorphous alloy material is crisp especially, therefore healing up, it is broken when opening closure, to be very easy to again, cause assembling process more loaded down with trivial details, simultaneously, the 3-D triangle dry reactor of existing structure has magnetic hysteresis loss and the larger defect of eddy current loss.Therefore, design and develop one easy to assembly, the smaller 3-D triangle dry reactor of magnetic hysteresis loss and eddy current loss seems particularly important.

Utility model content

The technical problems to be solved in the utility model is: provide a kind of easy to assembly, the 3-D triangle dry reactor that magnetic hysteresis loss and eddy current loss are smaller.

The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:

A kind of 3-D triangle dry reactor, comprise iron core, outer wall at described iron core is provided with insulating barrier, is wound with coil at described insulating barrier outer wall, is provided with cushion block and lower cushion block at the two ends of described iron core, on cushion block, be provided with upper yoke on described, on described upper yoke, cover has upper clamping piece, on described lower cushion block, is provided with lower yoke, and on described lower yoke, cover has lower clamping piece, on described lower clamping piece, be provided with feet, between described lower clamping piece and feet, pass through bolted; It is characterized in that: described iron core is made up of three core limbs, and each core limb stacks into cylindrical-shaped structure by multiple iron-cored cakes, is folded with air gap plate between adjacent iron-cored cake.

As preferred version, the utility model has also adopted following technical scheme:

Described iron-cored cake is made up of non-crystaline amorphous metal soft magnetic material.

Advantage and the good effect that the utlity model has are: because the iron core in the utility model is made up of three core limbs, each core limb stacks into cylindrical-shaped structure by multiple iron-cored cakes, between adjacent iron-cored cake, be folded with air gap plate, therefore compare with conventional art, there is winding around advantage easily; Because iron-cored cake is made up of non-crystaline amorphous metal soft magnetic material, compare with the iron core that traditional silicon steel disc is repeatedly made, have advantages of that magnetic hysteresis loss and eddy current loss are smaller.

Embodiment

For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 1 to Fig. 4, a kind of 3-D triangle dry reactor, comprises upper clamping piece 1, upper cushion block 2, coil 3, iron-cored cake 4, air gap plate 5, lower cushion block 6, lower clamping piece 7, feet 8, bolt 9, screw rod 10 and iron yoke 11; Wherein: iron core is made up of three core limbs, each core limb stacks into cylindrical-shaped structure by multiple iron-cored cakes 4, between adjacent iron-cored cake 4, be folded with the air gap plate 5 that regulates inductance parameters, be provided with insulating barrier at outer wall unshakable in one's determination, coil 3 is wound in described insulating barrier outer wall; Upper cushion block and lower cushion block are arranged at respectively two ends unshakable in one's determination, and iron yoke 11 comprises upper yoke and lower yoke; Upper yoke is arranged at the upper surface of cushion block, and lower yoke is arranged at the lower surface of lower cushion block, and upper clamping piece 1 is set on upper yoke, and lower clamping piece 7 is set on lower yoke, and feet 8 is arranged at the below of lower clamping piece 7, fastening by bolt 9 between lower clamping piece 7 and feet 8; Fastening by screw rod 10 between upper clamping piece 1 and lower clamping piece 7.

As preferred embodiment, in order to reduce magnetic hysteresis loss and the eddy current loss of reactor, the iron-cored cake 4 in this specific embodiment is made up of non-crystaline amorphous metal soft magnetic material.

Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve, within all should still belonging to patent covering scope of the present utility model.
