Description
Technical field
The present invention relates to a kind of skeleton and noninductive winding method that is used for superconducting switch.
Background technology
Superconducting switch is to be parallel to the superconducting magnet two ends; Realize the vitals of superconducting magnet operation with closed ring; Have and break off and two kinds of operating states of conducting, correspond respectively to superconducting switch and change normal state (by without hindrance state-transition for the resistance state is arranged) into and change superconducting state (is without hindrance state by the state-transition of resistance is arranged) into by normal state by superconducting state.
Because the superconducting switch in the closed loop only is to utilize its impedance effect, so superconducting switch need be made into noninductive coil, and to eliminate its induction reactance influence to circuit and environment, to make its induction coefficient be zero or approach zero as far as possible.The key technology of making superconducting switch is the structural design and the technique for coiling of the noninductive coil of function admirable, so the winding method of noninductive coil just influences and determined the performance of superconducting switch.
Disclosed noninductive coil winding method is the section lead doubling end to end that is used for coiling among the Chinese patent CN1056245C, carries out coiling simultaneously from the folding section, and this winding method is practical for common electrified wire; And for the bigger thick and stiff superconducting line of elasticity; The thread stranded cable of stranded superconductive particularly, the fold position radius of curvature is bigger, is difficult for fixing; Can not closely arrange between coil turn, and superconducting line has the hidden danger existence that is fractureed in the doubling process.Chinese patent CN1095591C has proposed the single winding of a kind of interlayer switching-over counter-rotating and has carried out the noninductive coiling of superconducting switch, and the noninductive coil of this method coiling is an even level, and is at least two-layer; Whether can be for total number of plies by 4 two kinds of situation eliminating, the forward coiling is different with the order of reverse coiling, and the number of turn will be according to circumstances different and change to some extent, so there is significant limitation in this method, and winding process complicacy.
Summary of the invention
The objective of the invention is to propose a kind of superconducting switch skeleton and noninductive winding method of the thick and stiff superconducting line that is applicable to, particularly stranded superconductive cable, a kind of specifically double wrap method that is the basis with the separate type skeleton.
The noninductive coiling of superconducting switch of the present invention is to realize with a kind of form of separating skeleton; Skeleton is made up of cylindrical drum and circular end plate two parts that an end has flange; The non-flanged end of cylindrical drum is carved with S type groove; Recess width is identical with wire diameter with the degree of depth, and the circular end plate of skeleton compresses to link into an integrated entity with crimping screw and the non-flanged end of cylindrical drum and forms the superconducting switch skeleton.
The superconducting switch of coiling both can be used for the conduction cooling type superconduction magnet among the present invention, also can be used for liquid helium immersion type superconducting magnet.General conduction cooling type superconduction switch skeleton is selected metal material for use, like brass, red copper, stainless steel etc.; Liquid helium immersion type superconducting switch skeleton is selected non-metal insulating material for use, like fiber glass epoxy, and polytetrafluoroethylene, bakelite or the like.For metallic framework, before coiling, need earlier skeleton to be done insulation and handle, like the spraying polytetrafluoroethylene film, paste polyimide film etc.
The present invention begins coiling from the midpoint of superconducting line; The mid point doubling of superconducting line is partly embedded in the S type groove of skeleton, and groove has certain radius of curvature, and the outlet at groove two ends is very level and smooth arc surfaces; Can not cause damage during coiling to superconducting line, and the hidden danger that do not fractureed of superconducting line.After superconducting line embeds S type groove; Circular end plate connected together with crimping screw and the non-flanged end of cylindrical drum be fixed; Behind the mid point process S type groove of superconducting line, two sections coiling direction is identical end to end, under same coiling tension force, carries out double wrap then simultaneously side by side.Closely neat with arranging between the lead of every layer of the superconducting switch coil of the method coiling, and do not have the restriction of the number of plies, odd-level, even level all can.
The noninductive winding method of superconducting switch of the present invention both can be the circular cross-section superconducting line for the not restriction of shape of superconducting line, also can be the square-section superconducting line.
