Description

Make the method for hyperconductive cable
Technical field
The present invention relates to a kind of method of making hyperconductive cable.
Background technology
Known hyperconductive cable is owing to the shortcoming that at room temperature flexibility is not enough is restricted its application.
Summary of the invention
Purpose of the present invention just provides that a kind of to make a kind of at room temperature be the method for soft hyperconductive cable, and this cable is at room temperature very tough and tensile, and its superconducting characteristic can be used.
According to said method of the present invention, it is characterized in that: preferably be on the flexible pipeline one the layer that selectively is made of plastics is set, and when applying lubricant, according to the helix on the described ground floor, at least one deck superconduction band is set, one steel pipe is set afterwards, an auxiliary tube is set at last again, thereby between described steel pipe and described auxiliary tube, form vacuum.At room temperature, lubricant has required flexibility, becomes solid simultaneously under relatively low temperature, thereby necessary mechanical resistance can be provided.Can make solid particle and mix lubricant selectively.
And, can still, can change the angle of inclination of superconduction band being arranged on many layer superconduction bands according to assisted plastic layer of the present invention and superconduction band, afterwards, another plastic layer is arranged on last one deck superconduction band.
Also have, can make according to lubricant of the present invention by silicone oil, peanut oil, oil jelly, machine oil or organic fatty, perhaps by for example have viscosity to the low temperature of negative 60 degree for negative 20 degree in the temperature interval and for example to be lower than temperature be that the lubricant of fusing hard under the relatively low temperature of 110 ° of K is made lubricant of the present invention.
Hybrid particles is preferably made by following material, it is the mixture of several particles in the particle of aluminium oxide, zirconia, manganese oxide, boron nitride, tungsten carbide or ceramic particle or metallic particles or plastic grain or these types, by with mix lubricant, can reduce static friction at an easy rate, and can utilize capillary force to keep lubricant selectively.
In addition, the size according to hybrid particles more of the present invention is 0.01 to 10 micron.
Brief Description Of Drawings
Illustrate in greater detail the present invention with reference to the accompanying drawings, wherein:
Fig. 1 represent to comprise the multilayer superconducting layer, twined a refrigerator pipes according to cable of the present invention;
Fig. 2 represents the schematic cross-section of cable innermost layer part;
Fig. 3 represents the schematic cross-section of each superconducting layer.
Realize best mode of the present invention
As shown in Figure 1, the refrigeration piping 1 that comprises the inner circular of the liquid nitrogen cold-producing medium that is used within it flowing according to cable of the present invention.For example, pipeline 1 can be approximately 3 centimetres circular pattern by diameter and makes.Pattern 1 can be by making such as aluminium, steel etc.Be tied with multilayer superconduction band 2 around pattern, for example can be 8 layers.Each layer superconduction band 2 winds up.Winding can make cable have predetermined flexibility like this.Twine the superconduction band in different ways, can also eliminate axial magnetic field basically.But, there is no need alternately to twine in the opposite direction the superconduction band.For example, can twine three ground floors in same direction, and twine the 4th layer in the opposite direction.Twining superconduction band 2 like this can make it stick together mutually basically each other.But, between the adjacent two layers superconduction band space can be arranged.Between the winding layer of superconduction band 2, insert plastic layer 13.For example, the thickness of these plastic layers is approximately 50 microns.By inside and outside bellows 4,5 around the outermost layer of superconduction band and stacked plastic layer.Between these bellowss 4,5, form vacuum, thereby between each layer of superconduction band 2, form thermal insulation.By keeping this vacuum state along cable setting and connected pump.Between bellows 4,5, be provided with a plurality of winding spacers 6, so that between described bellows 4,5, keep at a distance.These spacers 6 are made of plastics.Below spacer 6, selectively be provided with multilayer aluminium film 7.Bellows 4,5 can be used as whole cable predetermined flexibility is provided.Outer tube 5 covers one deck insulating material 8.This insulating barrier also is not cooled, and has ambient temperature.For example, insulating barrier 8 can be made by polypropylene and polyethylene.Insulating barrier 8 is coated with the sheath of making by such as copper, lead or aluminium, also is provided with the sheath 9 that other one deck is made by polyethylene.
According to the present invention, before using superconduction band 2, during or afterwards, can be on the surface of described superconduction band 2 film forming mode, coat the lubricant 11 that mixes with solid particle 12.
Handle in the temperature interval is-20 ℃ to+60 ℃ scope or during bending cable, lubricant 11 has the characteristic of reducing friction, described lubricant 11 is fluid in described temperature interval, and not sticking especially.But, under relatively low temperature, when for example being 110 ° of K to 4.2 ° of K, the lubricant hardening, and therefore under such temperature, show very big mechanical resistance.
The solid particle 12 that has mixed reduces at superconduction band or the lip-deep static friction characteristic of superconducting line.Therefore the grain shape of the rounded or sub-circular of the shape of some powder particle 12 can obtain basically the function function corresponding with ball bearing.The characteristic of some particle 12 can make lubricant remain on original position by capillary force, also can not make mixture too sticking, and lubricant is remained on the non-horizontal cross-section of cable.Lubricant 11 and the particle 12 that mixes also can be used for increasing heat conductivity in the mode that increases the heat conductivity between conductor and the flow system cryogen.
At low temperatures, superconduction band 2 remains on original position in the following manner, although promptly be subjected to the effect of electromagnetic force, superconduction band 2 still can not move.
The example of the lubricant lubricant that can be silicone oil, peanut oil, oil jelly (gelly) or machine oil or organic fatty or " lubricated jelly (gelly) " or other have appropriate viscosity at interval at predetermined temperature, this lubricant also mix with the mixture of several particles in the particle of aluminium oxide, zirconia, magnesium oxide, boron nitride, tungsten carbide particle or ceramic particle or metallic particles or plastic grain or these types.With suitable size distribution particle 12, promptly the size of circular granular is 1 to 50 micron, and short grained size is 0.01 to 10 micron.Amounts of particles and size distribution situation can be selected like this,, vertically remain on described high temperature following time at interval at described cable that is, and these mixtures do not flow in cable, and when described cable may be crooked, mixture was enough to flow to allow superconduction band 2 to slide.
If lubricant is gluey (gelly) type, can not need the granule composition.
Fig. 3 represents the cross section of each superconduction band.Its whole width are approximately 4 millimeters, and full depth is approximately 0.2 millimeter.The thickness of each filament is 0.02 millimeter.The distribution of filament can be at random, perhaps is the row, column orientation.In the superconduction band, 1 to 1000 filament is arranged generally.
