<p>The aim of the invention is to reduce an installation area occupied by transformers inside a cubicle and to prevent the generation of vibrational noise and heat. The transformer structure (12) is constructed so that a molded transformer, in which a single-phase transformer is molded by a molding material, and current and instrument transformers, which are connected to the primary sides of the single-phase transformers, are molded integrally by a molding material. This transformer structure (12) is positioned and fastened in place inside a rectangular frame (14). Two of these frames (14) are stacked in the vertical direction and connected to each other. A transformer apparatus (16) which contains two of such frames (14) are stacked and connected in the vertical direction is installed inside a cubicle (10). The molded transformers are installed inside the frames (14) so that the central axes of the windings of the transformers are placed horizontally. <IMAGE></p> |
