PROBLEM TO BE SOLVED: To provide the winding wire support structure of a gas-insulated transformer which prevents the deterioration of insulation performance without generating a gas gap in a contact part between an internal winding wire and an external winding wire, prevents a position deviation in each winding wire due to an impact in transportation, and has high reliability, safety, and economic efficiency.SOLUTION: In the winding wire support structure of the gas-insulated transformer 10, an iron core main leg 1 with silicon steel plates laminated and frames 8 fixed in the upper and lower parts, and the internal winding wire 2 and the external winding wire 3 concentrically wound around the main leg 1 are stored in a tank 9 for internally sealing the insulated gas. The respective winding wires 2, 3 are supported by the frames 8 via axial insulation support materials 7. A plurality of flexible interval pieces 6 for internally sealing a gaseous matter are removably arranged at prescribed interval in the circumferential direction between the winding wires 2, 3. |
