<p>PROBLEM TO BE SOLVED: To improved the structure of a transformer for a gas-insulated instrument which has insulating performance to a high-frequency surge improved by providing a ground electrode plate facing a potential-fixed plate. SOLUTION: The transformer for the gas-insulated instrument is equipped with an iron core 1, a secondary coil 2 wound around the iron core 1 across a secondary coil former 3, and a primary coil 4 wound around the secondary coil across a primary coil former 5 and a potential-fixed plate 6. Further, the transformer has the ground electrode plate 12 buried in the primary coil former 5 and a grounding conductor 14, connecting the ground electrode plate 12 to a ground point (e), connected to the ground electrode plate 12 on the inner circumferential side of one end 5a of the primary coil former 5.</p> |
