That is, since the conventional winding block 29 is integrated in a figure eight shape, it is necessary to apply a rectangular wire 13 made of a large number of rectangular insulated conductors around a dedicated winding jig to form the same. was there. Therefore, the winding work of the winding block 29 requires a high degree of skill. In addition, it was necessary to attach a vertical duct after laminating the upper disk winding and the lower disk winding, and to install an insulating spacer between the disk windings, which took a lot of man-hours to assemble the winding. I was Also, it takes time to displace the rectangular insulated conductor at the transition between the upper disk winding and the lower disk winding. Furthermore, the use of a rectangular insulated conductor has the disadvantage that eddy currents in the windings increase and the losses in the windings are large. An object of the present invention is to reduce the number of winding steps of a winding block,
Another object is to reduce the winding loss.

能である。## EQU2 ## 10 × 31 × 8 mm × 2 mm = 4960 mm 2 , which is almost the same as the conductor cross-sectional area of 40 conventional winding blocks 29. Therefore, the number of winding blocks 17 having the configuration shown in FIG. 1 is very small, which is one fourth of the conventional case. The reason why such a large difference occurs is that the winding block 17 is changed from the conventional rectangular electric wire 13 to the transposition conductor 18, so that a large number of element conductors 18A can be collectively wound. Because it has become. In the configuration of the conventional winding block 29, it is impossible to form dozens of flat rectangular insulated conductors 12 into a figure-eight winding.

る。The winding block 17 having the structure shown in FIG.
Since the dislocation conductor 18 is wound around the winding frame in a cylindrical shape, skilled work for processing the winding into a figure eight as in the prior art is unnecessary, and the number of winding steps is greatly reduced. Furthermore, in the case of the conventional case, the connection of the rectangular electric wire 13 had to be made to a total of 80 places on the vertical leads 10 and 11 in the case of 40 winding blocks 29. On the other hand, the connection of the dislocation conductor 18 is made by connecting the vertical leads 10 and 10 in the case of ten winding blocks 17.
A total of 30 locations are required, including 20 locations at 11 and 10 locations at the connecting portion 14, and the number of winding steps is reduced from this point as well.

Thereby, the bending strength of the dislocation conductor 18 itself is increased, and the mechanically strong winding block 17 can be formed. Therefore, it can sufficiently withstand the electromagnetic mechanical force generated at the time of short circuit. FIG. 3 is a cross-sectional perspective view showing a configuration of a dislocation conductor used in a winding block of a stationary induction device according to another embodiment of the present invention. The dislocation conductor 19 is composed of a plurality of strand conductors 19A covered with a heat-fusible resin film (not shown) stacked in the left-right direction and arranged in two rows in the upper and lower directions. It is wound so as to leave a gap.
The lamination position of the wire conductor 19A is configured to change as it goes in the length direction. As the restraining member 19B, for example, an insulating cord made of polyester or a heat-shrinkable tape is used. Since the dislocation conductor 19 is not covered with the insulating paper 18B unlike the dislocation conductor 18 of FIG. 2, it has excellent heat dissipation. Therefore, this dislocation conductor 19
When used for the winding block 17 as shown in FIG. 1, the cooling characteristics of the winding block 17 are improved. In addition, the wire conductor 1
Since 9A is thermally fused, the winding block 17 has excellent mechanical properties.
