Description

Superconducting transformer

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.C type transformer is a kind of in electronic transformer, and its iron core is pieced together by a pair " C " shaped iron core.The power supply that C type transformer is generally applicable in electric equipment, instrument, communication apparatus is used.

For powerful C type 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.In addition, because C type transformer is easily because iron core expands with heat and contract with cold, and cause riveted joint to loosen, cause iron core air gap to increase, cause noise.

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, port type iron core and the winding coil on described port type iron core, described square shape iron core and coil are all arranged in described insulation shell, and described coil is superconductor winding, also be enclosed with superconducting material in the outside of described coil, in described insulation shell, be sealed with cold-producing medium.

Further, described square shape iron core comprises the C shaped iron core of two mutual splits, and is enclosed with steel band at two described C shaped iron cores, is provided with elastic construction in described steel band.

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, liquid hydrogen, liquid argon, liquid oxygen or liquefied air.

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 comprises insulation shell 1, port type iron core 3 and the winding coil 2 on port type iron core 3, square shape iron core 3 and coil 2 are all arranged in insulation shell 1, and coil 2 is superconductor winding, also be enclosed with superconducting material in the outside of coil 2, in insulation shell 1, be sealed with cold-producing medium 4.Square shape iron core 3 and coil 4 are all immersed in cold-producing medium 4, and preferred cold-producing medium 4 is liquid nitrogen, liquid hydrogen, liquid argon, liquid oxygen or liquefied air, 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.

As shown in Figure 2, square shape iron core 3 comprises the C shaped iron core 31,32 of two mutual splits, and is enclosed with steel band 33 at two C shaped iron cores 31,32, can be provided with elastic construction 34 in steel band 33.In use, when steel band causes loosening because iron core expands with heat and contract with cold, the elastic force of elastic construction 34 can ensure that steel band 33 is in tension all the time to transformer, ensures to there will not be larger iron core air gap between two C shaped iron cores 31,32, thus effectively avoids noise to produce.

Preferably, can arrange crashproof layer 5 respectively in the upper and lower surface of insulation shell, this crashproof layer 5 can avoid transformer impaired because of collision, improves use safety.Crashproof layer 5 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.
