PURPOSE:To form an induction electrical apparatus such as a small-sized light- weight GIS direct-coupled type transformer convinient for transport by interposing a metallic bellows on the GIS side and miniaturizing the induction electrical apparatus so as to conform to the size of a GIS sheathe. CONSTITUTION:A metallic bellows 7 is fitted between a parting plate 8 on the transformer side and a spacer 17 for partition in order to absorb both mounting tolerances, absorb a difference between both thermal elongation and reduce the transmission of vibrations from a transformer. SF6 gas 13 the same as a GIS16 is encapsulated into the metallic bellows 7. Accordingly, the length of lead wires 6 can be shortened only by sections corresponding to conventional bellows 7, and the size of the inner diameter of the metallic bellows 7 can be reduced up to the same size as the inner diameter of the GIS sheathe 11 required fro insulating SF6 gas, thus miniaturizing and lightening the metallic bellows 7, then minimizing the size of the whole mounting sections. |
