CONNECTION STRUCTURE FOR GAS INSULATION ELECTRIC APPARATUS AND GAS INSULATION ELECTRIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To enable absorption of a mutual displacement between a bushing and a transformer body even when the displacement has been caused, and secure sufficient ground insulation strength at the bushing's part penetrating a frame.;SOLUTION: According to an embodiment, a connection structure for a gas insulation electric apparatus comprising a frame inside which insulation gas is encapsulated, an electric apparatus body housed in the frame, and a bushing that is configured to have an internal conductor inside an insulator and is provided so as to penetrate a wall part of the frame is a connection structure for electrically connecting the electric apparatus body and the bushing. A connection member connecting the electric apparatus body with the internal conductor of the bushing at least partially has a flexible cable made by bundling conductors made of thin wires and coating them with insulators made from polymeric material, and has a stress cone for interface insulation that is fitted to the outer periphery of the insulation coating. The stress cone is pressed and fixed to the insulator of the bushing by a pressing member made from insulation material to connect the conductor of the cable with the internal conductor.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
