B. Outline of the Invention The present invention is to fill a swollen semi-cure mica resin compound in a non-impregnated portion where a void is likely to occur in a high voltage rotating machine winding for resin impregnation, and wind a mica insulating tape on it.

C. Conventional technology and problems In the full impregnation method, the coil after mica taping is directly inserted into the iron core and connected, and the impregnating resin is impregnated under vacuum pressure while being integrated with the iron core, and then heat cured in a high temperature drying furnace. ing.
Conventionally, when an epoxy resin is used as an impregnating resin, it has a low viscosity because it is necessary to surely impregnate the insulating composition, but the viscosity is reduced by about one digit at the beginning of the heat curing process, and the resin is Easy to leak. When the resin flows out, non-impregnated portions containing voids are generated between the insulating components and between the conductor and the insulating components. If there is a void-free portion between the insulating components and between the conductor and the insulating component, a partial discharge will occur due to the voltage applied to the insulating layer, which will cause discharge deterioration of the insulating layer and eventually lead to dielectric breakdown. There is a fear.

E. Embodiment An embodiment of the present invention will now be described with reference to FIGS. Fig. 1 shows a full coil. The impregnated resin is prevented from flowing out at the coil end parts A, B, C, D and the lead-out wire lead-out parts E, F, which are the main resin outflow paths. ing.

The solid line represents the upper side during curing, the broken line represents the lower side, and the lower side was almost the same in the three examples. The comparative example shows that the rise of tan δ of the upper side coil was large and the outflow amount of the resin was large.
On the other hand, in the examples, the rise of tan δ is relatively small and the outflow amount of the resin is small. From the above, it can be seen that the characteristics are even improved significantly by the resin outflow prevention treatment described in this example and by using the mica tape containing the curing accelerator.

The coil used this time has a 6.6KV class insulation, and Fig. 6 shows the tan δ-V characteristic of the coil. The solid line represents the one on the upper side during curing, and the broken line represents the one on the lower side, and the lower side was almost the same in the two examples. In Comparative Example A, tan δ-V of the upper side coil
The rising of the curve is large, which means that the outflow amount of the resin was large. Comparative Example B has the effect of the resin outflow prevention treatment using the semi-cured mica resin compound, and the rise of the tan δ-V curve is considerably small. Furthermore, in Example 3, it was shown that the use of the calcined type mica suppressed the rise of the tan δ-V curve and was effective in preventing resin outflow.

The above-mentioned calcined type integrated mica tape is very advantageous for preventing resin outflow because the mica is made dense, but it is inferior to the non-sintered type in impregnation property, and conversely, the non-sintered type integrated mica tape is impregnated type. On the other hand,
It is disadvantageous in preventing resin outflow. Therefore, from the half of the insulating layer, a dense baked type mica tape of mica, which is advantageous for preventing resin outflow, is used, and from the half to the inside, a non-fired type mica tape with excellent impregnation is coated with a curing accelerator. By using, it is possible to obtain a resin having good impregnating property and having little tan δ-V characteristic after curing with almost no resin outflow during curing.

In addition to the above-mentioned treatment and insulation, use a non-fired type integrated mica tape in which a curing accelerator such as imidazole is applied to the conductor side of the ground insulating layer with a thickness of 20 to 50%. , An insulating layer is formed on the remaining part by using a baked type mica tape. The above-mentioned curing accelerator has an action of shortening the curing time of the impregnated resin such as amines, imidazoles, boron trifluoride amine complex, organic acid metal salts, organic metal complexes, and hydrolyzable organosilicon compounds. Anything can be used. For the lead wire side end insulation and the non-lead wire side end insulation, only a calcined type mica tape may be used.

The curve shows the tan δ-V characteristic of the side that became the upper side during curing, and Comparative Example A, Comparative Example B, Comparative Example C, and Example 4 are arranged in order from the top. The tan δ-V curves of the side that became the lower side upon curing were almost the same as those of the side that became the upper side of Example 4 in all examples. The rise of the tan δ-V characteristic curve is considered to be because the resin flowed out and a void was generated. As can be seen from FIG. 7, in this embodiment, ta
