The fastening structure is characterized in that an iron core supporting plate (4) is vertically arranged between each coil (1) and each iron core (2), a plurality of coil supporting strips (5) are arranged on the peripheries of the coils (1), the coils (1) and the iron cores (2) which are arranged in the lower clamping part (3) and the lower clamping part (3) are horizontally bound together through a plurality of binding straps (6), and the binding straps are pressed to be close to the coils (1) by the pulling screws (7). The fastening structure has the advantages that force of the coils to the amorphous alloy iron cores is greatly reduced, thereby effectively improving the overall mechanical strength of the transformer and anti-sudden-short circuit capacity during sudden short circuit test.
Description
Technical field
The utility model is a kind of structure of transformer, specifically relates to a kind of fastening structure of amorphous transformer.
Background technology
Daily material generally has two kinds: a kind of is crystalline material, and another kind is an amorphous material.So-called crystalline material is meant that the atomic arrangement of material internal is followed certain rules.Otherwise inner atomic arrangement is in random state, then is amorphous material, general metal, and its inner atomic arrangement is orderly, all belongs to crystalline material.
Amorphous alloy is compared with crystal alloy, in physical property, chemical property and mechanical properties significant variation has taken place all.Amorphous alloy based on ferro element is an example, and it has high saturated magnetic induction and low-loss characteristics.Because such characteristic, amorphous alloy material has possessed wide application space in various fields such as electronics, Aeronautics and Astronautics, machinery, microelectronics.For example, be used for aerospace field, can alleviate power supply, weight of equipment, increase payload.Be used for civilian electric power, electronic equipment, can dwindle power volume greatly, raise the efficiency, strengthen antijamming capability.Minitype iron core can be widely used in the transformer among the integrated services digital network ISDN, the effect of non-crystaline amorphous metal mystery has vast market prospect, wants energy savings, by adopting the method for new material, reducing the no-load loss value of distribution transformer, is an effectively approach.
Amorphous alloy transformer is a kind of energy-conservation low-loss power transformer of excellent performance, and it utilizes amorphous alloy material to replace silicon steel sheet to make iron core, is characterized in that no-load loss is low can reduce 70%-80%.Because amorphous alloy material is very responsive to mechanical stress, be that tensile stress or bending stress all can influence its magnetic property, therefore, amorphous alloy transformer core can not bear the effect of mechanical force, simultaneously, the anti-short circuit capability of the square coil of transformer is also relatively poor.At present, mostly there is the potential safety hazard of bearing sudden short circuit ability inadequate natural endowment in the amorphous alloy transformer that moves in labour in a large number.
Summary of the invention
The purpose of this utility model provides a kind of integral body of amorphous transformer and is stranded the tighten fixing structure, to reduce and to avoid the amorphous alloy transformer core sensitiveness of mechanical force to external world, improves the square coil anti-short circuit capability.
The purpose of this utility model is achieved by following technical scheme:
A kind of fastening structure of amorphous transformer in the downside folder of frame structure, is set up in parallel some coils and iron core, and the common factor place at mutual coil by vertically drawing screw rod with screw-rod structure coil to be strained up and down, is characterised in that:
Supporting bracket unshakable in one's determination vertically is set between coil and iron core;
In the periphery of coil many coil stays are set;
To be arranged in the coil and the iron core of downside folder by many binding straps with horizontal direction, together with the colligation of downside folder together, and binding strap is drawn the screw rod compressing to be close to coil sides.
Further, described coil is three groups of left, center, right.
Further, described binding strap is even three at interval of upper, middle and lower.
Further, described supporting bracket unshakable in one's determination and coil stay are that thickness is the epoxy resin board of 6-10mm.
Further, 4-6 root coil stay is set in the periphery of every group of coil.
Adopt the technical program, after transformer body is assembled into one, put coil stay, with binding strap iron core, coil, the binding of downside folder are tightened to one (concrete operations available dedicated colligation machine) again in the coil periphery.Because the utility model power that coil is suffered is delivered to supporting bracket unshakable in one's determination, pass to the downside folder by supporting bracket unshakable in one's determination again, separate thereby make between suffered power of coil and the iron core, coil is reduced greatly, the anti-sudden short circuit ability when having improved the mechanical strength ability of transformer integral body effectively and having done the sudden short circuit test to the active force of amorphous synthetic iron core.
Superiority of the present utility model and beneficial effect: 1. reduce the vibrations of iron core, coil; 2. improved anti-sudden short circuit ability.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of fastening structure of the utility model amorphous transformer.
Among the figure, the 1st, coil, the 2nd, iron core, the 3rd, downside folder, the 4th, supporting bracket unshakable in one's determination, the 5th, coil fagging, the 6th, binding strap, the 7th draws screw rod.
Embodiment
Further describe structure of the present utility model below in conjunction with accompanying drawing.
A kind of fastening structure of amorphous transformer in the downside folder 3 of frame structure, is set up in parallel some coils 1 and unshakable in one's determination 2, common factor place at mutual coil 1, by vertically drawing screw rod 7 with screw-rod structure coil 1 to be strained up and down, following hand hay cutter folder 3 is frame-like, is positioned at the bottom of transformer:
Between coil 1 and unshakable in one's determination 2, supporting bracket 4 unshakable in one's determination is set vertically; Act directly on the iron core in order to isolated coil 1 suffered short-circuit force.
In the periphery of coil 1 many coil stays 5 are set; In order to the protection coil, and by the power dispersion of coil stay 5 with binding strap 6.
To be arranged in the coil 1 of downside folder 3 and unshakable in one's determination 2 by many binding straps 6 with horizontal direction, together with 3 colligations of downside folder together, and binding strap 6 is drawn screw rod 7 compressings to be close to coil 1 side.Colligation back together is whole fastening, very close to each other, eliminates vibrations.
Described coil 1 is three groups of left, center, right.This is general common structure.
