エンチが生じやすくなることである。In superconducting windings, it is generally believed that minute movements during operation cause a transition to normal conductivity, and the support and fixation of the windings must be as completely strong as possible. However, because of the structure of the superconducting field winding, which is wound directly into a slot machined into the winding mounting shaft of the rotor of a superconducting generator, it is difficult to apply tension during winding. However, a method has been adopted in which the wire is fixed to teeth such as a spacer after winding. The disadvantage of this method is that when the rotor is rotated at the rated speed, cooled down to 4.2K, and excited at the rated current, there is a strong centrifugal force and electromagnetic force, and the difference in shrinkage rate due to cooling causes the windings and slots to A gap is created between the teeth that make up the winding, resulting in insufficient support and fixation of the winding, which makes quenching more likely to occur.

である。In order to achieve the above object, the present invention provides a superconducting field winding in which a superconducting wire and an insulator are arranged in a slot of a rotor of a superconducting generator. The field winding of the superconducting generator is characterized in that the spacer is formed from a non-magnetic, high-resistance, high-density, and high-strength metal whose surface is subjected to insulation treatment.

Further, it is preferable that the lower ends of the side insulating spacers arranged on the left and right side surfaces of the superconducting field winding in the slot protrude inward in the radial direction of the rotor from the upper surface of the lower insulating spacer.

In addition, if the lower insulating spacer is made of a non-magnetic, high-strength, high-resistance metal and a finely divided high-density metal, it may be made of stainless steel, nickel-based alloy, etc., and silver or mercury of the high-density metal. It is better to consist of

強度であることは発電機回転子内の高い遠心力によって
変形しないことを意味する。When using the lower insulating spacer at the bottom of the slot, which is made of non-magnetic, high-resistance, high-density, and high-strength metal with an insulated surface, the lower insulating spacer has a large centrifugal force due to its high density at rated rotation. The force acts to strongly push the coil inside the slot and firmly support and fix the coil between it and the wedge at the top of the slot. Also, being non-magnetic does not cause hysteresis loss due to magnetic field fluctuations. The high resistance keeps the induced current small when the field current changes. High strength means that it will not be deformed by high centrifugal forces within the generator rotor.

There are a lower insulating spacer 7 and side insulating spacers 8 and 9. The upper insulating spacer 6 and the lower insulating spacer 7 also have the role of a clipage block for preventing creep dielectric breakdown.

出来る。Taking a 10100O class two-pole superconducting generator as an example, the radius of the bottom of the slot 2 is about 250 mm. 3600
If it is rotating at the rated speed of rpm, the angular velocity due to rotation is ω = 2 x π x 6O-377 (radian/second)
It is. Calculating the acceleration due to rotation at the bottom of slot 2 is α−rω2=25 oxa 772=3.553x
107mm/s2, which is 36% of the acceleration of gravity.
This is 25 times the acceleration. At the bottom of slot 2 is a semicircular piece of stainless steel (density 8.0 x 10
-'kg/mm3), the lower insulating spacer 7 exerts a pressure of 4.46 MPa on the field winding 4. Typically, insulating spacers are glass fiber reinforced plastic (FR)

g/mm' or less. Also, conventionally the lower insulating spacer 7
As shown in FIG. 2, the shape is rectangular and the size is about 5 x 40 mrn2. Therefore, in the present invention, it is possible to obtain four times the pressure due to the difference in density between stainless steel and FRP, three times the pressure due to the difference in shape, and 12 times the pressure due to the synergistic effect.

さらに集中を起こす。Further, the cross-sectional shape of the lower insulating spacer 7 is semicircular,
Accordingly, the bottom of the slot 2 has a semicircular shape. The teeth 10 forming the slots 2 are cooled to 4.2K while the rotor is rotating, and when a field current flows, a large centrifugal force and a large centrifugal force due to the mass of the field winding 4 and the teeth 10 are applied to the field winding. It supports the large electromagnetic force that acts on it. When the shape of the roots of the teeth 10 suddenly changes, the stress generated by supporting these centrifugal forces and electromagnetic forces becomes further concentrated.

When the lower ends of and 9 protrude inward in the radial direction of the rotor from the upper surface of the lower insulating spacer 7, the creep distance from the field winding 4 to the teeth 10 at ground voltage or the winding attachment shaft 1 can be increased. In addition, in the configuration shown in FIG. 3, the side insulating spacers 8.9 reach the bottom of the slot 2 and do not obstruct the radial movement of the lower insulating spacer 7, so that the centrifugal force acting on the lower insulating spacer 7 during rotation is reduced to superconductivity. I can convey everything to my body 3.

A lower insulating spacer 7 is shown whose minor axis is in the radial direction. This depends on the stress distribution near the bottom of slot 2.
A half-ellipse shape may alleviate stress concentration more than a semicircle, and in such a case, the short axis of the ellipse is determined according to the stress distribution.

However, since it is finely reinforced with high-strength metal, the strength can be ensured, and the equivalent resistance to eddy current can also be increased, making it possible to reduce eddy current loss when the field current changes. The cell shown in FIG. 5 has hexagonal cells, but the cell may be of any shape as long as it can ensure strength.
