PURPOSE:To prevent high voltage electric shock accident within a cubicle and enable miniaturization of power transformer facilities. CONSTITUTION:A transformer Tr arranged within a cubicle 10 is molded by a molding material 12 made of an insulating material. A current transformer CT and a transformer PT for meters connected to the primary side of the transformer Tr are also molded by the molding material 12 with the transformer Tr. That is, the transformer Tr, current transformer CT and transfer PT for meters are integrally molded by the molding material 12 so that its high voltage portion is not exposed to the outside. With this constitution, the high voltage portion is not exposed at the inside of the cubicle. Thereby, there is no fear of electrical shock for the person who is engaged with cleaning of each apparatus and maintenance work. As a result, operation life of the current transformer and transformer for meters can be extended, and deterioration and damage due to electrical shock by insects and rats can be prevented. |
