Description

A kind of electrophoretic coating insulating method of high-temperature superconductor band
Technical field
It is exhausted the present invention relates to high temperature superconducting materia technical field, more particularly to a kind of electrophoretic coating of high-temperature superconductor band Edge method.
Background technology
Superconductor because its there is zero resistance, high current density the characteristics of, for high-intensity magnetic field application, lossless electric current transmit Deng with unique technical advantage.Especially two generation conductor of high-temperature superconductor coat currently with yttrium barium copper oxide as representative, stagnation temperature Degree is higher than liquid nitrogen temperature, and refrigeration cost is lower, with the fast-developing and maturation of its practical band technology of preparing, will be further Expand the application field of superconduction.
When the first two is usually the bare tape not comprising insulating barrier for the product that high-temperature superconductor band producer provides the user, and mesh Be required for the band that insulate in preceding most of application, thus it is actually used before insulation processing is carried out to band.At present, for wire Primary insulation processing mode include wrapping polyimide insulative adhesive tape and apply two kinds of insulated paint.But wrapping insulating tape and biography All there are following several respects for superconducting tape in the japanning insulating method of system.
Wrapping insulating method is simple, and dielectric strength is high, but uses the superconducting magnet engineering electricity of wrapping insulation band coiling Current density reduction and low temperature thermal conductance variation.On the one hand, because the Kapton Tape commonly used is thicker, and to make band completely exhausted Edge, the phenomenon that can also there is adhesive tape overlap during general wrapping, this band for just making wrapping good is greatly increased on thickness, made Its average engineering current density significantly reduces.On the other hand, due to polyimides, thermal conductance is poor in itself, the band after wrapping It is to be filled with heat insulation layer in its both sides, causes its low temperature thermal conductance to be deteriorated, the low-temperature stability of superconducting magnet is greatly reduced.Its Secondary, when the superconducting magnet of wrapping band coiling carries out dipping solidification, due to the cladding of dielectric film, epoxy glue is difficult to permeate whole completely Individual coil, causes its solidification effect poor.
And traditional japanning insulating method is usually used in the insulation processing of enamel covered wire, however, smooth relative to surface texture For copper conductor, two generation high-temperature superconducting coating band cross-sectional structures are special, are mainly shown as:1st, with very thin thickness, about 0.1 to 0.2 millimeter, and flakiness ratio is big, more than 10;2nd, it is multiple-layer stacked structure, band both side surface is rough.Therefore, tradition Japanning insulating method to directly apply to two generation high-temperature superconducting coating band effects poor, there is more leak source.
Publication No. CN 1588565, publication date is that the Chinese patent literature of on 03 02nd, 2005 discloses one kind and carries High temperature superconducting materia of insulating barrier and preparation method thereof, be related to a kind of high temperature superconductive wire of aliphatic acid insulation coating, band and Its preparation method, it is characterised in that it is made up of high-temperature superconductor core, core clad, insulating coating, preparation process be by into After the high temperature superconductive wire of product, strip surface are cleaned, immersion iknsulating liquid hydroxy-carboxylic resin coating material box carries out coating It is heating and curing at 500 DEG C -600 DEG C after coating, applied thickness is 10-20 μm.
The patent document, the aliphatic acid insulation coating material used during enamel-cover, with existing other enamel-cover material phases Faster than curing rate, the insulation coating time is short, reduces the impaired possibility of high temperature superconductive wire, band, and insulating properties reach pressure-resistant 500 volts, its process is simple, favorable repeatability, it is adaptable to large-scale use.But, it is applied to two generation high-temperature superconductor multilayer knots It is poor for the irregular structure japanning effect of its side surface during structure situation;Meanwhile, its temperature that is heating and curing is for 500 DEG C -600 DEG C, far above the highest bearing temperature of two generation high-temperature superconductor bands, superconducting characteristic degeneration risk is higher.
Publication No. CN 104575873A, publication date is that the Chinese patent literature of on 04 29th, 2015 discloses one kind The insulating method of conductor of high-temperature superconductor coat, directly coats insullac, main bag mainly on conductor of high-temperature superconductor coat Include following steps:(1) conductor of high-temperature superconductor coat before coating insullac is pre-processed;(2) to treated Conductor of high-temperature superconductor coat is coated insullac;(3) curing process is carried out to insullac.
The insulating method of conductor of high-temperature superconductor coat disclosed in the patent document, its conductor of high-temperature superconductor coat for preparing Thickness of insulating layer is uniform, the phenomenon that superconductivity wire insulating barrier can be avoided locally exposed, and with good electrical insulation capability and very Good mechanical performance.But, the side surface japanning effect similarly for two generation high-temperature superconductor band sandwich constructions is poor;Meanwhile, It is applied directly between the insullac of high-temperature superconductor conductive surface and conductive surface metal only exist merging physically, its knot It is weaker with joint efforts.
The content of the invention
