摘要： PURPOSE:To miniaturize an expansion joint by making the inside diameter and the outside diameter of a bellows type expansion part, which connects the vessels of disconnecting switches with each other, smaller than the inside diameter and the outside diameter of the flange parts at both ends, respectively. CONSTITUTION:The two vessels 6 of disconnecting switches 4, which have charge parts 7 within, are connected with each other by two insulating spacers 8 and a bellows type expansion joint 5. Flanges 10 for engaging with the spacers 8 are made at both ends of the expansion joint, and the expansion joint has an internal conductor 13 and, at both ends, electric field relaxing shields 14 within. The diameter of the expansion part 9 is made smaller than the inside diameter of the flange 10, and the outside diameter of the expansion part 9 is made smaller than the outside diameter of the flange 10. Hereby, a tie rod 12 is directly connected to the spacers 8 and the flanges 10, and thus the expansion joint is miniaturized, and the cost is reduced.
