COMPOUND ISOLATING TYPE GAS INSULATED SWITCHGEAR

摘要

PROBLEM TO BE SOLVED: To provide a compound insulating type gas insulated switchgear of improved reliability by suppressing behavior of foreign metal substance and development of surface discharge to raise insulation performance.

SOLUTION: Between a high voltage conductor 1 and a metal vessel 2, a cylindrical barrier insulator 5 which is coaxial with them is inserted. The barrier insulator 5 is insulated/supported by a protruding part of a support insulator 3. A shrinkage absorbing material 8 is sandwiched between the support insulator 3 and the barrier insulator 5. The shrinkage absorbing material 8 can absorb displacement in axial and radial directions.
