Description
Technical field
The utility model relates to field transformer, particularly relates to a kind of superconducting transformer.
Background technology
Transformer is a kind of converting electric power and static electromagnetic device electric energy being delivered to another circuit from a circuit.EI transformer is a kind of in electronic transformer, and its iron core is by " E " matrix and " " matrix stacks up I, is referred to as EI transformer according to its shape.EI transformer generally uses as power frequency (low frequency) transformer, power transformer and audio frequency transformer.
For powerful EI transformer, because its coil exists copper resistance, there is iron resistance in iron core, can produce copper loss and iron loss, and then cause transformer to generate heat during work, if overload seriously may burn out transformer.
Utility model content
The purpose of this utility model proposes a kind of superconducting transformer, can bear high load, have stronger overload capacity.
For achieving the above object, the utility model provides a kind of superconducting transformer, comprise insulation shell, day font iron core, insulated coil skeleton and the coil of winding on described insulated coil skeleton, described day font iron core, insulated coil skeleton and coil be all arranged in described insulation shell, and described coil is superconductor winding, also be enclosed with superconducting material in the outside of described coil and insulated coil skeleton, in described insulation shell, be sealed with cold-producing medium.
Further, described day font iron core is provided with at least one leakage field space iron core.
Further, described leakage field space iron core is made up of permeability magnetic material and gap backing plate, and is positioned at the centre position of described day font iron core.
Further, crashproof layer is respectively equipped with in the upper and lower surface of described insulation shell.
Further, described crashproof layer adopts fiber.
Further, described cold-producing medium is liquid nitrogen.
Based on technique scheme, the utility model adopts superconductor to make winding, and is coil and the coated superconductor of insulated coil skeleton, and makes transformer be operated in necessary working temperature by cold-producing medium, thus the effect obtained without copper loss and iron loss, and then realize stronger overload capacity.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of an embodiment of the utility model superconducting transformer.
Fig. 2 is the structural representation of the Sino-Japan font iron core of the utility model superconducting transformer embodiment.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
See Fig. 1,2, the superconducting transformer of the present embodiment comprise insulation shell 1, day font iron core 2, insulated coil skeleton 3 and the coil 4 of winding on insulated coil skeleton 3, day font iron core 2, insulated coil skeleton 3 and coil 4 are all arranged in insulation shell 1, and coil 4 is superconductor winding, also be enclosed with superconducting material in the outside of coil 4 and insulated coil skeleton 3, in insulation shell 1, be sealed with cold-producing medium 8.Day font iron core 2, insulated coil skeleton 3 and coil 4 are all immersed in cold-producing medium 8, and preferred cold-producing medium 8 is liquid nitrogen, necessary working temperature can be operated in for transformer, thus make the winding of superconductor and superconducting material present superconducting state at the working temperature, thus the effect obtained without copper loss and iron loss, and then realize stronger overload capacity.
Day font iron core 2 can also arrange at least one leakage field space iron core 7.Leakage field space iron core 7 can be made up of permeability magnetic material 72 and gap backing plate 71, is positioned at a day centre position for font iron core 2.And day font iron core 2 to be formed by stacking by E type silicon steel sheet 21 and I type silicon steel sheet 22, and the middle part extension of E type silicon steel sheet 21 is leakage field space iron core 7.
Owing to being provided with at least one leakage field space iron core in the leakage field space of superconducting transformer, leakage flux can be made to be significantly improved, and then improve transformer impedance, greatly reduce the stray loss of transformer, reduce the adverse effect of leakage field simultaneously.
Preferably, can arrange crashproof layer 6 respectively in the upper and lower surface of insulation shell, this crashproof layer 6 can avoid EI type transformer impaired because of collision, improves use safety.Crashproof layer 6 preferably adopts fiber.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
