<p>PROBLEM TO BE SOLVED: To provide a gas-insulated switchgear for suppressing temperature increase in foundation concrete in the gas-insulated switchgear, where the plurality of points of a conductive tank 1 for accommodating a conduction conductor by sealing an insulation gas are grounded to a ground mesh 5 buried in the foundation concrete at multiple points via a grounding wire 6. SOLUTION: The gas-insulated switchgear is provided with a conductive trestle 18 for supporting a conductive tank 1, and the conductive trestle 18 constitutes a closed circuit, where an induction current being generated by current that flows through the conduction conductor flows.</p> |
