Abstract

PURPOSE: To increase mechanical strength of coils as well as to reduce the size by supporting the coils by means of a casing through an insulator being wrapped arround the coils.
CONSTITUTION: Stuffings, such as both inner coils 1a and outer coils 1b being wound around iron cores 2, are put into a casing 3. Then insulators 8a and 8b are inserted between the stuffings and the casing 3 and are fixed by means of wedges which are not shown in the illustration. Therefore, even if short-circuit current happens to flow, it leaks to the casing through the insulators 8a and 8b, and is supported by the casing. As a result, mechanical strength of the outer coils 1b increases; thus redusing the size of the casing because no doubling plates are required. By so doing, mechanical strength of the coils can be increased, as well as their sizes can be reduced.
