<p><P>PROBLEM TO BE SOLVED: To provide a gas-insulated potential transformer capable of performing remote connecting/disconnecting operation readily and surely in safety. <P>SOLUTION: The gas-insulated potential transformer 10 comprises a transformer body section 11 serving as a transformer, and a means 14 for controlling a contact mechanism section 13 for switching electrical connection state with a gas-insulated switching device 12. When an operator performs input operation for switching electrical connection state from an input means 31 provided in a remote control means 14, a drive control means 30 provided in the control means 14 can perform switching operation for connecting/disconnecting contacts 21a, 21b provided in a casing 25 with/from a contactor 22 through a rotating shaft 27, a contact mechanism driver 18 and a drive rod 23. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
