Description
Technical field
The present invention is the parts in a kind of superconduct physical unit, is the vitals that belongs in the superconduct physical unit.Be specifically related to a kind of small size low loss superconductor NbTi/Cu pipe inner cable superconducting conductor joint design.
Background technology
Superconducting magnet in the superconduct physical unit is owing to be subjected to the restriction of superconducting conductor factory length, and the joint of superconducting conductor (particularly in large-scale superconducting magnet) is inevitable.The effect of NbTi/Cu pipe inner cable superconducting conductor (calling CICC in the following text) joint is that electric current and cold matter are transferred to another conductor from a conductor, and its basic demand is that resistance, A.C.power loss and the volume of joint is the smaller the better.Superconduction CICC joint also requires (liquid state or gaseous state) cold matter not had the ground of leakage and transfer to another conductor from a conductor except requiring small resistor and small size.The performance of superconduction CICC joint has material impact to superconducting magnet operation stability and fail safe.
Tradition NbTi/Cu hyperconductive cable poling joint technology mostly is to adopt the method for two end conductors by low-resistance copper material overlap joint with transmission current, and the method that adopts cross-over connection is to transmit cold matter.Because adopt low-resistance copper material overlap joint, the A.C.power loss of joint is big, contact resistance is big; Because adopt the cold matter cross-over connection of transmission, the joint volume is difficult to miniaturization; Owing to be the overlap joint of final stage cable, it is bigger to connect length.Therefore traditional superconduction CICC joint can not be arranged on superconducting magnet inside, also is not useable for having in the magnet of alternating magnetic field, has hindered the application of large-scale CICC superconducting magnet.
Summary of the invention
The present invention proposes a kind of small volume low loss superconductor CICC connector structure, after being the full transposition of sub-cable with two CICC end conductors, connect through interting, be aided with the center cold flow channel, and with its overall vacuum sealed package, it is big to efficiently solve above-mentioned traditional superconduction CICC joint A.C.power loss, and contact resistance reaches the very large problem of volume greatly.
Technical scheme of the present invention is as follows:
Small volume low loss superconductor CICC connector structure, the layout shaft that cold flow channel is arranged in the middle of it is characterized in that comprising, the sub-cable of superconducting line that stretches out in two the superconducting conductor shells in left and right two ends is fixed on outside the layout shaft, intert and connect at sub-cable joint place, sub-cable has inner casing outward, and inner casing has shell outward, the tapered body in layout shaft two ends, the sub-cable of superconducting line is tightly connected after extruding between tapered sleeve and shell and the superconducting conductor shell near being set with tapered sleeve outward with layout shaft two-end part bullet.
Be distributed with a plurality of axially extending bores or interspersed groove on the described layout shaft.
The outer sub-cable of superconducting line of layout shaft is fastened through spiral.
Left and right two sections respectively of layout shafts are by spiral or be made of welded connection.
Superconduction CICC joint of the present invention mainly comprises tapered sleeve, layout shaft, inner casing, shell and the sub-cable of the superconducting line of untiing.Each component function is as follows:
Tapered sleeve: be used for conductor two-terminal cable is dissipated into constant bearing, and connection superconducting conductor shell becomes an airtight container with joint shell.
Layout shaft: be used to the sub-cable of superconduction that inner support is provided, and cold flow channel is provided, improve cooling effectiveness to greatest extent, improve conductivity simultaneously; Be distributed with a plurality of axially extending bores or interspersed groove around the layout shaft, as cold flow channel, be used for and sub-cable between cold matter exchange, increase thermal convection, and can further reduce A.C.power loss.
Shell: be used to the sub-cable of superconduction that external support is provided, it tightens the back guaranteeing the requirement of sub-cable voidage, and forms an airtight container with tapered sleeve welding back.
Inner casing: be used for when shell tightens and the safety of the sub-cable of soldering and sealing time protection superconduction, and improve the reliability of conductivity and joint assembling.
Sub-cable: drawn by the two ends conductor, separate according to designing requirement and be certain grade of sub-cable, and be wrapped in a spiral manner outside the layout shaft, the length of pitch has determined length of said joint, the size of A.C.power loss and the flow resistance of cold matter.
The invention effect
Because adopted the sub-cable technology that replaces entirely, A.C.power loss can be reduced significantly.And the interspersed interconnection technique of the sub-cable that adopts can reduce connection resistance effectively.Adopt the spiral of sub-cable to twine, make that connecting length is reduced significantly.As adopt the interspersed spiral of the sub-cable of one-level to be intertwined and connected, length of said joint can be reduced to full cable and connect 1/4 to 1/8 of length.The structure of employing center cold flow channel integrated design is so the volume of joint is decreased to below 1/4 of traditional jointing.
