Abstract
The utility model relates to an air gap spacer, in particular to a reactor iron core air gap spacer and an iron core reactor using the same. The spacer comprises a body larger than or equal to an iron core in cross section and paired protrusions extending out from the body. The iron core reactor comprises the iron cores, an upper yoke, a lower yoke and the spacers, the spacers are arranged at air gaps and gaps between the iron cores and the upper yokes and between the iron cores and the lower yokes respectively, the paired protrusions of the spacers form clamping slots, and fixing support strips are arranged in the clamping slots to prevent iron cake silicon steel sheet from sliding down. Structures are improved, the performance of the reactor is improved, and possibility of partial discharge is lowered.
Description
Technical field
The new shape of this practicality relates to a kind of air gap gasket, relates in particular to a kind of core of reactor air gap gasket and has used the iron core reactor of this pad.
Background technology
Reactor is generally the solenoid form of lead coiled, wherein, in solenoid, inserts iron core so that obtain the reactor of bigger inductance, claims iron core reactor.Iron core in the iron core reactor generally comprises parts such as yoke, stem stem and pad, constitutes magnetic circuit.Stem stem is many to be divided into even segment by a plurality of air gaps, establishes the pad that is made up of nonmagnetic substance in the air gap, occurs to prevent the magnetic circuit saturated phenomenon.Iron core column then is with coil groups outward, is typically provided with insulating cylinder between each coil and the iron core.
At present, mostly the air gap gasket of iron core reactor is rectangle, and measure-alike with core section, to cooperatively interact.This kind reactor displacement downwards occurs easily at the silicon steel sheet at when assembling indivedual iron cores edge, and discus respective silicon steel disc overlap joint up and down after the landing can cause that the suspension electric discharge phenomena are arranged between core of reactor.Thereby, use the reactor of this kind air gap gasket the problem of unstable properties can occur.And in case go wrong, reactor must be through reprocessing processing, and its process is complicated, old raising of use, is a problem demanding prompt solution.
Summary of the invention
In order to solve the problem that landing appears in core of reactor air gap sheet easily, to reach the purpose that reduces iron core column suspension discharge probability, the new shape of this practicality provides the anti-silicon steel sheet displacement of a kind of core of reactor " H " shape air gap chip architecture, and this technical scheme is following:
Air gap gasket comprises the body more than or equal to the iron core cross section, also comprises prolonging the paired evagination that body outwards extends and.
Further, said air gap gasket is " H " shape, and the centre is a rectangle, and rectangle extends for four jiaos and four evaginations.
Further, said air gap gasket is an insulating sheet material.
Use the iron core reactor of aforementioned air gap gasket, comprised iron core, go up yoke, lower yoke and pad, be equipped with said pad between each air gap, the same yoke of iron core, lower yoke space.
Further, the paired evagination of said pad forms draw-in groove, is provided with fixed stay in the aforementioned draw-in groove.
Said air gap gasket paired evagination through on body, extending, form draw-in groove, so that add fixedly accessory; Like stay etc.; To stop that each discus silicon steel sheet glides, improve structure, strengthen the reactor performance; Reduce the partial discharge probability, make reactor performance safety, stable, reliable in running.
Description of drawings
Close accompanying drawing below and embodiment further specifies the present invention.
Fig. 1 is this preferred embodiment structural representation;
Fig. 2 is that Fig. 1 is along hatching line A-A directional profile figure;
Wherein: 1 is yoke on the reactor, and 2 is " H " shape air gap gasket, and 21 is " H " shape air gap gasket abduction evagination, and 3 is a kind of insulating stay, and 4 is iron core cake of electric reactor, and 5 is the reactor lower yoke
Embodiment
As shown in Figure 1, be the application drawing of the new shape preferred embodiment of this practicality, this figure is an iron core reactor, by iron core 4, the insulating stay 3 going up yoke 1, lower yoke 5, be arranged on the air gap gasket 2 between aforementioned each parts and be fixed in iron core 4 both sides forms.As shown in the figure; Three identical iron cores of structure are arranged between yoke 1, the lower yoke 5; Iron core is divided into a plurality of iron core cakes 41 by a plurality of air gaps; Iron core is divided into 3 iron core cakes 41 by two air gaps in the present embodiment, said air gap, places topmost 1 space of the same yoke of the first iron core cake, places the 3rd iron core cake bottom to be equipped with air gap gasket 2 with 5 spaces of lower yoke.Wherein, A-A shown in promptly overlaps with 1 space of the same yoke of the first iron core cake to hatching line.Set air gap gasket 2 protrudes in the paired evagination formation draw-in groove of iron core cake 41 cross section parts between each space, is provided with insulating stay 3 in the draw-in groove, is located at each iron core both sides, so that chucking withstands the air gap sheet from both sides, prevents the silicon steel sheet displacement.
Fig. 2 be Fig. 1 along hatching line A-A directional profile figure, as shown in the figure, air gap gasket 2 is " H " shape; And comprise intermediate rectangular body and 4 abduction evaginations 21 that protrude in iron core cake 41 (in Fig. 2, not showing) cross section part; This abduction evagination 21 in pairs, forms draw-in groove; Insulating stay 3 embeds wherein, does the support fixation effect.
Except that above-mentioned instance, the new shape of this practicality can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all belong in the protection range of the new shape requirement of this practicality.
