Abstract

PURPOSE:To miniaturize the outer configuration by arranging the winding axes of single-phase voltage transformers and connecting said transformers in multiphases. CONSTITUTION:The winding axes A0-C0 of the single-phase transformers A-C are arranged in parallel, and enclosed in a container 5 wherein an insulating gas is filled. The transformers are connected in multiphases. In this constitution, the distance between the cores of the transformers can be expanded without enlarging the outer configuration of the container. Therefore, the interference between the phases due to the leakage of magnetic fluxes is not caused. Even though the cores are saturated by DC currents, the large electromagnetic force is not generated between the windings and the cores, and the increase of sizes in the outer configuration can be avoided.
