Abstract
The utility model discloses an anti-short circuit type amorphous power transformer. A plurality of coils and iron cores are arranged in parallel inside a lower side fixture of a frame structure, and vertical pulling screws in the screw structure are used for tightening coils in the up-and-down direction at intersection positions of coils. The amorphous power transformer is characterized in that iron core supporting plates are arranged vertically between coils and iron cores, a plurality of coil supporting bars are arranged on the peripheries of coils, a plurality of binding tapes are used for binding coils and iron cores in the lower side fixture with the lower side fixture in the horizontal direction, and binding tapes are pressed against the coil side by pulling screws. The anti-short circuit type amorphous power transformer has the advantages that the acting force of coils on amorphous crystal iron cores is greatly reduced, and the overall mechanical strength of the transformer and the sudden-short-circuit resistance during sudden-short-circuit tests can be effectively improved.
Description
Technical field
The utility model relates to a kind of power transformer, specifically a kind of Short Circuit withstand type amorphous power transformer.
Background technology
Daily material generally has two kinds: a kind of is crystalline material, and another kind is amorphous material.So-called crystalline material refers to that the atomic arrangement of material internal is followed certain rule.Otherwise inner atomic arrangement is in random state, 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 occured all.Take ferro element as main amorphous alloy as example, it has high saturated magnetic induction and low-loss characteristics.Due to such characteristic, amorphous alloy material has possessed wide application space in the 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 greatly dwindle power volume, raise the efficiency, strengthen antijamming capability.Minitype iron core can be widely used in the transformer in integrated services digital network ISDN, the effect of non-crystaline amorphous metal mystery has wide market prospects, 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 affect 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 of a large amount of in-service operations.
The utility model content
The purpose of this utility model is to provide a kind of tired tighten fixing structure of integral body of amorphous transformer, 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 utility model purpose realizes with the following methods: a kind of Short Circuit withstand type amorphous power transformer, in the downside folder of frame structure, be set up in parallel some coils and iron core, common factor place at mutual coil, by vertically drawing screw rod with screw-rod structure, coil to be strained up and down, be 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 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.
Described coil is three groups of left, center, right.
The periphery of described every group of coil arranges 4-6 root coil stay.
Described binding strap is three, even interval, upper, middle and lower.
Described supporting bracket unshakable in one's determination and coil stay are that thickness is the epoxy resin board of 6-10mm.
The beneficial effects of the utility model are: adopt the technical program, after transformer body is assembled into one, put coil stay in the coil periphery, then with binding strap, iron core, coil, the binding of downside folder are tightened to one (concrete operations available dedicated binding machine).Power coil is suffered due to the utility model is delivered to supporting bracket unshakable in one's determination, then passes to the downside folder by supporting bracket unshakable in one's determination, thereby makes coil suffered
Power and iron core between separate, coil is reduced greatly to the active force of amorphous synthetic iron core, effectively improved the mechanical strength ability of transformer integral body and done the sudden short circuit anti-sudden short circuit ability in when test.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is made concrete further instruction.A kind of Short Circuit withstand type amorphous power 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, lower 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 iron core in order to the isolated suffered short-circuit force of coil 1.
In the periphery of coil 1, many coil stays 5 are set; In order to protecting coil, and by coil stay 5, the power of binding strap 6 is disperseed.
To be arranged in coil 1 and the iron core 2 of downside folder 3 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.Whole fastening, very close to each other after colligation together, eliminate vibrations.
Described coil 1 is three groups of left, center, right.This is general common structure.
Described binding strap 6 is three, even interval, upper, middle and lower.Generally tied up by three binding straps 6 of level and be advisable, both satisfied and tied up needs, increase again workload little.
Described supporting bracket unshakable in one's determination 4 and coil stay 5 are the epoxy resin board of 6-10mm for thickness.
4-6 root coil stay 5 is set in the periphery of every group of coil 1.Therefore compare with conventional art, the utlity model has following beneficial effect: 1. reduce the vibrations of iron core, coil; 2. improved anti-sudden short circuit ability.
