本発明は電機子巻線のハーフターンコイルを改良した超
電導回転電機に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a superconducting rotating electric machine in which a half-turn coil of an armature winding is improved.
回転型機の単機容量の増大、並びに効率向上の手段とし

電導界磁巻線を内蔵した回転子との間の空隙中に配設し
、固定子鉄心に固定された空隙電機子巻線とを備えた超
電導回転電機が用いられるようになってきた。As a means of increasing the capacity of a single rotary machine and improving efficiency, the armature winding, which was conventionally housed in the slots of the stator core, has been replaced with a shielding stator core without slots and a superconducting field winding. Superconducting rotating electric machines have come to be used which include a gap armature winding arranged in a gap between the built-in rotor and a gap armature winding fixed to a stator core.
空隙中に配設した電機子巻線は、固定子鉄心にスロット
が無いことから当然ティースもないので。The armature winding placed in the air gap naturally has no teeth since there are no slots in the stator core.

手段としては、特開昭58−218845号公報に記載
されているように。When directly exposed to the strong magnetic field from the rotor, the coil conductors that make up the armature windings suffer from large eddy current losses, which makes them difficult to match with conventional coils housed in the stator core slots. Differently, bundled wire was used, which was made by twisting and bundling thin formal-insulated wires with a diameter of about 1 inch. This cooling means for the wire bundle is as described in Japanese Patent Application Laid-Open No. 58-218845.
束線間に冷却パイプを配置して冷却するものがある。し
かしこれは、束線と冷却パイプとを並べて、互に転位し
ているので、絶縁側素線の冷却には。Some devices provide cooling by placing cooling pipes between the wire bundles. However, in this case, the wire bundle and the cooling pipe are arranged side by side and transposed to each other, so it is not possible to cool the strands on the insulated side.
更に強力なものが望まれていた。また冷却パイプは、そ
れ自体のうず電流が問題とならないように。Something even more powerful was desired. Also, make sure that the cooling pipes themselves do not suffer from eddy currents.

じた電流が流れ、固有抵抗の大きい分だけ、冷却パイプ
に大きな抵抗損を発生させることになり。A metal 1, such as stainless steel, is used, which has a higher electric resistivity than copper, which is the material of the armature coil. For this reason, even if you try to connect the cooling path at the same time as the electrical path as in the past,
Reliable silver brazing was difficult due to the inclusion of different materials such as stainless steel pipes and the extremely large number of thin insulated wires.On the other hand, the electrical constants of the electric circuit as an armature winding Among the resistance and actance, the reactance value is dominant, so the armature current that flows in both electric circuits is restricted by the reactance. This means that if a half-turn coil consisting of a stainless steel cooling pipe and an insulated wire is electrically connected at both ends, a current corresponding to the reactance will also flow in the cooling pipe, which has a higher electrical resistivity than the coil conductor. The greater the flow and specific resistance, the greater the resistance loss in the cooling pipe.
回転電機の効率低下および冷却作用の大幅な低減を来た
すという欠点があった。This has the drawback of reducing the efficiency of the rotating electric machine and significantly reducing the cooling effect.

する。The present invention provides an armature winding using a half-turn coil that eliminates liquid leakage from the cooling liquid flow path of the armature winding, provides high reliability, and reduces resistance loss due to circulating current in the cooling pipe. The purpose of the present invention is to provide a superconducting rotating electric machine having the following features.

の絶縁側素線を転位しただけでなく。In the present invention, a rotor having a superconducting field winding,
A shielding stator core without slots is placed around the stator core with a gap in between, and a plurality of half-turn coils placed in the gap and fixed to the stator core are connected in a predetermined manner to form an armature winding. In a superconducting rotating electric machine, a half-turn coil is formed by winding a plurality of insulated wires with a first transposition around a cooling pipe extending outward from the end of the coil to form a coil bundle. A desired half-turn coil is obtained by using a plurality of bundled wires and performing a second transposition with each other, and the end of this half-turn coil is connected to a Hiji conductor that connects between the upper and lower half-turn coils or between the coil and external wiring. At the same time, an electrical insulating layer is provided on the surface facing the cooling pipes, and the cooling pipes are bundled into coils and sleeves are fitted on them. The gap at the end of the coil is made liquid-tight by arc welding and connected to the coolant distribution member, and the insulated wire of the coil bundle is not only transposed.

抵抗損を0に近く低減している。さらに冷却パイプの端
面も液密にしたので。Furthermore, the coil bundle wires are also transposed to make the characteristics of the armature windings uniform both above and below in a strong magnetic field, and by insulating the cooling pipe from the insulated wires, resistance loss due to circulating current is reduced. It has decreased to close to 0. Furthermore, the end surface of the cooling pipe was also made liquid-tight.
漏液が無くなり信頼性を向上するものである。This eliminates leakage and improves reliability.

Seven pairs of first transpositions (also referred to as transpositions) are attached using seven side wires (C), and this is compression-molded into a rectangular cross section to make a coil bundle (10), which is insulated. Wrap the tape (11). This coil bundle wire (1
A desired half-turn coil (2) is made by mutually performing a second transposition using a plurality of coils (2). At this time, when the insulating tape (11) at the end of the coil is peeled off and silver soldering is applied, the formal insulating layer of the side strand (2) disappears, and the ends of each strand (2) become integrated. The clip ■ is silver-soldered to this, and the electrical insulation layer (9a) made of ceramic spraying is placed on the opposite surface of the cooling pipe ■ (make it a little longer to allow for extra space).
, and insulate the coil (■) from the cooling pipe. The length of the clip ■ should be at least 6 times the first transposition pitch of the coil bundle wire (10), and the upper and lower coils (5a) = (5b

The end face of the gap between the pipe (9) and the sleeve (12) is liquid-tightly sealed and welded.

流密度が平均化する。Although the coil bundle wire (10) has a large cross-sectional area, seven incomplete insulated mesh wires (■) each having undergone the first transposition are collected and attached around the cooling pipe, and the cross-sectional area is Since the second transposition is carried out using a plurality of coil bundle wires (io) which are compression-molded into a rectangular shape and wrapped with insulating tape (11), the current in each insulating mesh wire is small even in one strong magnetic field. Density averages out.

する。Therefore, there is no need to increase the cross-sectional area of the half-turn coil unnecessarily. Since the cooling pipe (1) is arranged at the center of each coil bundle (10), the cooling efficiency is good. Each cooling pipe ■ has an electrically insulating layer (9a
), electrical insulation is formed from the bare conductor at the connection part of the half-turn coil ■, and the upper and lower coils (sa)
, (sb) cooling pipe is a ceramic connecting pipe (14
), the circulating current through the cooling pipe (2) can be brought close to zero. Since the cooling pipe extends outward from the coil (2) and is connected to the cooling fluid distribution member in a liquid-tight manner, there is almost no leakage and reliability is improved. Further, since the insulating mesh wire is a formal wire, the formal coating of that part is automatically peeled off by the high temperature of silver brazing, making brazing easier and reducing the number of man-hours. Moreover, since the fluid connection is made on the outside of the clip (1) in the axial direction, it is easy to work with, and even in the unlikely event of fluid leakage, there is no need to disassemble the electrical connection part, which has the advantage of being easy to maintain.
