FIG. 1 shows the structure of the superconducting generator of the present invention. FIG. 2 shows details of the superconducting field winding 1 used in FIG.

子巻線となっている。In the superconducting generator, the superconducting field winding 1 is provided on the winding mounting shaft 3 of the rotor 2, and a large magnetic flux is generated in the armature winding 5 of the stator 4 by its strong magnetomotive force. Occurs. For this reason, the portion corresponding to the tooth 6 of the current machine is made of a non-magnetic material, and is an air gap armature winding as a whole.

る。The superconducting field winding 1 is composed of a superconducting conductor directly wound around the winding mounting shaft 3. This is because the superconducting field winding 1 may cause a so-called quench (loss of superconductivity) due to a minute movement of the conductor, and therefore it is necessary to create an environment in which the superconducting field winding 1 can be excited in a stable manner.

高い巻線構造が求められている。Therefore, the superconducting field winding 1 is housed in the cooling tank 1A, and the liquid helium flowing in the pipe 1B circulates in the cooling tank 1A as indicated by the arrow, so that the superconducting field winding 1 is circulated. Not only is the cooling of No. 1 sufficiently secured, but a winding structure having high rigidity is required in order to eliminate friction and other factors of heat generation.

る。For this reason, in the conventional superconducting power generator, not only the straight line portion but also the end turn portion has the all-round slot structure in which the winding mounting shaft 3 is slotted. The shaft material of the winding mounting shaft 3 is made of, for example, A286 alloy or Inconel, which has a large proof strength at extremely low temperature and room temperature. Since these shaft materials are not only high in yield strength but also extremely hard materials, machining of the end turn portion for forming the entire circumferential slot requires a lot of time and tool consumption.

として使えることが分かった。Generally, a ferromagnetic metal material has a large decrease in toughness at an extremely low temperature, so it has not been used for a member to which a large electromagnetic stress or centrifugal stress acts. The above-mentioned A286 alloy and Inconel are nonmagnetic or weakly magnetic. Recently, it has been found that 13Ni2Mo steel is a ferromagnetic material and has not only a sufficient yield strength as a winding mounting shaft but also a decrease in toughness at cryogenic temperatures as compared with room temperature, so that it can be used as a winding mounting shaft.

る。The use of a ferromagnetic material having sufficient strength and toughness for the winding mounting shaft has the following advantages. 1. The magnetic resistance of the superconducting field winding part is slightly reduced, and the field magnetic flux density of the armature winding part can be increased by about 30% with the same magnetomotive force, so that the superconducting generator can be made compact. 2. The magnetic flux density of the superconducting field winding portion is 4 to 5T, and magnetic saturation occurs even in the ferromagnetic winding axis, but most of the magnetic flux magnetically penetrates the magnetic pole portion, and therefore acts on the superconducting field winding itself. The magnetic flux density is significantly reduced compared to the case where a non-magnetic winding mounting shaft is used.

The characteristics of the superconducting field winding in the case of a non-magnetic winding mounting axis are determined by the peak magnetic field generated by the magnetic flux concentration at the ends of the winding due to the geometrical shape of the winding, and its magnitude is The peak value of the fundamental wave magnetic field (two-pole magnetic field in the case of a two-pole machine) that contributes to power generation is often 1.5 to 1.6 times. On the contrary,
A peak magnetic field of about the magnitude of the fundamental wave magnetic field appears on the axis of the ferromagnetic winding attachment.

トとティースとが形成される。In view of these advantages, as shown in FIG. 2, the winding mounting shaft 3 is made of a ferromagnetic metal having sufficient toughness at extremely low temperatures, and the superconducting field winding 1 is formed according to the shape of the slot. Of the superconducting field winding has a straight axial slot 9 which is machined with a slot mirror or the like in parallel with the winding mounting axis 3 and the end turn slot 10 of the superconducting field winding is a lathe machined winding. It is composed of circumferential teeth 11 which are perpendicular to the mounting shaft 3 and parallel to the circumferential direction. The joint between the two kinds of teeth is deleted for the convenience of machining, but a part remains as the magnetic protrusion 12. This removed portion is filled with a ferromagnetic metal spacer 13 along the shape of the field winding. In this way, slots and teeth having a shape close to the entire circumference slot are formed.

には基本波磁場程度のピーク磁場が作用する。The superconducting field winding is formed as a winding in the portion having the slot shape around the entire circumference. The operating state of the superconducting field winding is as follows. That is, the magnetic pole portion 14 which is magnetic in most of the field magnetic flux, the magnetic axial teeth 9, the circumferential teeth 11 and the magnetic protrusions 12 are formed.
Then, a peak magnetic field of about the fundamental wave magnetic field acts on the superconducting field winding itself, passing through the metal spacer 13.

This is very advantageous as compared with being regulated by a magnetic field of ~ 1.6 times. Although the ferromagnetic metal spacer 13 placed on the end turn portion cannot exhibit the rigidity equivalent to the original full-circumferential slot, by passing a large amount of magnetic flux, the magnetic flux density of the superconducting field winding is reduced to enhance the excitation stability. There is.

1 is cut, and a metal spacer 13 which is a pre-manufactured connection part having the same shape as the corner part is cut at the cut part.
Is provided, and the teeth 9 are formed in the axial direction by the metal spacer 13.
Since the tooth and the circumferential tooth 11 are connected to each other, the manufacturing time of the winding mounting shaft 3 can be greatly reduced by eliminating the machining for forming the tooth and the slot along the corner. became.

A field winding can be realized. The superconducting field winding 1 having excellent excitation stability can also be realized by supporting and fixing the straight portion with the slot wedge and supporting and fixing only both end turn portions with the retaining ring 17 as shown in FIG.

Although the high-temperature superconducting conductor is more strongly affected by the magnetic field than the low-temperature superconducting conductor and is reduced, the above configuration is more effective for the superconducting field winding made of the conductor of the high-temperature superconducting conductor. Further, it goes without saying that the present invention can be applied to a generator using an ordinary conductor.
