Abstract
The utility model discloses an alternating-current winding structure for a superconducting current limiter. The cross section of an alternating-current winding is in the shape of an ellipse or runway, so that the space can be effectively utilized, the weight is reduced, and the whole volume of the superconducting fault current limiter is reduced. Furthermore, the formed superconducting fault current limiter is economical and practical.
Description
Technical field
The utility model relates to a kind of AC Windings structure of superconductive current limiter, is particularly useful for the superconductive current limiter AC Windings of loose coupling structure.
Background technology
The core component of saturated core type superconductive failure current limiter is iron core, direct current winding and AC Windings, and its structural design is mainly considered cooperating of unshakable in one's determination and winding layout, and winding is arranged and had influence on its volume, iron core weight.
The superconductive current limiter of loose coupling structure to shown in the 1-4, includes center core limb 1, direct current winding 2, side column 3 and AC Windings 4 as Fig. 1-1, is found out by structure chart, and distance is very big between each AC Windings 4 outside placing, and is far longer than its safe distance.If do circular iron core according to routine, the one,, the space can not make full use of; The 2nd,, volume is big, and weight is big.For this reason, can be that AC Windings is surrounded lamination thickness increasing unshakable in one's determination with the side column iron core, the side column core section no longer is traditional Step Circular, but similar oval-shaped core section, its advantage applies can reduce the yoke height, and dwindles window size.The AC Windings that matches simultaneously is generally the high pressure winding, and winding inner diameter guarantees a certain minimum insulation distance with every bit unshakable in one's determination is all necessary, otherwise will be breakdown.If do circular (referring to Fig. 2), its shortcoming shows: do not match with 11 (the outer line 33 that covers unshakable in one's determination is arranged outward) unshakable in one's determination cross sectional shape; Increased window width unshakable in one's determination; Increased the slit between AC Windings 22 and the iron core, structure is sparse.The reorganization that also haves much room for improvement of this particular iron core structure of based superconductive flow restricter, the shape of AC Windings.
Summary of the invention
The purpose of this utility model provides a kind of AC Windings structure of superconductive current limiter, and it can be complementary with the iron core of similar elliptic cross-section in the superconductive current limiter loose coupling structure.
For achieving the above object, the utility model is taked following design:
A kind of AC Windings structure of superconductive current limiter, AC Windings cross section are ellipse or runway shape.
The AC Windings structure of the utility model superconductive current limiter is particularly useful for the superconductive current limiter of loose coupling structure, and its innovative point is: the one, reduced window size; The 2nd, made full use of the space between the AC Windings.Since the iron core of superconductive current limiter be the yoke cross section greater than the side column core section, use the AC Windings structure of this utility model, can reduce the iron core weight of yoke greatly.In addition, the space between the AC Windings is fully used, and has dwindled the outer profile size of superconductive current limiter simultaneously, is that economy is attractive in appearance again like this.
The utility model has the advantages that: can effectively utilize the space, reduce weight, dwindle the overall volume of superconductive current limiter, make the superconductive current limiter of formation have economy and practicality more.

Embodiment
As shown in Figure 3, Figure 4, the cross section of the AC Windings 1 of the utility model superconductive current limiter is oval (as Fig. 3) or runway shape (as Fig. 4).
Wherein, elliptic cross-section can be standard ellipse or non-standard ellipse; The runway tee section is made up of two Line Segment and two semicircle camber line butt joints.
Section morphology after the iron core 2 of two kinds of AC Windings 1 structures of the utility model and coupling (the outer line 3 that covers unshakable in one's determination is arranged outward) combines is shown in Fig. 3 a, Fig. 4 a.If the special iron core of the circular winding suit superconductive current limiter of tradition, the cross section as shown in Figure 2.Can obviously find out the superiority of the AC Windings structure of the utility model superconductive current limiter by above diagram---window size can be reduced and space between the AC Windings can be made full use of.
The winding conducting wire of two kinds of winding constructions of the utility model adopts strip conductor, round conductor, transposed conductor or paper tinsel formula lead all can.
Illustrate below in conjunction with specific embodiment:
Three-phase superconductive current limiter runway shape AC Windings with rated voltage 35kV, rated current 1500A, short circuit current 40kA, restriction electric current 20kA is an example:
The contrast of loose coupling superconductive current limiter runway shape AC Windings and circular AC Windings design parameter:
| AC Windings weight | Window width | Iron core weight | |
| Runway shape | 3.715t | 490mm | 26.4t |
| Circular | 4.1t | 590mm | 27.6t |
Compare both as can be seen, AC Windings has been saved 20m, has saved 9.39%; Length overall unshakable in one's determination has been dwindled 100mm, and weight has reduced 4.5%.Corresponding overall volume has also been dwindled.
