<p>PROBLEM TO BE SOLVED: To provide a transformer for a gas-insulated instrument that makes corona-free consideration unnecessary, by omitting a member to which high voltage is impressed directly, when the voltage is impressed after a cut-off and that is downsized and made light by achieving a simple structure. SOLUTION: Voltage-transforming elements 6 are arranged on an elevating plate 14 that moves up and down freely inside a container 8. On this elevating plate 14, an elevating device 15, or a driving means, is arranged. The up and down movements of the elevating device 15 make the elevating plate 14 and the voltage transforming elements 6 up and down, so that the high-voltage-side end part 12 of a high-voltage coil 3 is made to contact or detach from a high- voltage terminal 10.</p> |
