Claims

[Scope of utility model registration request]

A low-voltage winding and a high-voltage winding arranged concentrically, a shield ring arranged at each end of the windings, and a plurality of shield rings inserted at equal intervals in the circumferential direction between the windings and between the shield rings. A plurality of insulating cylinders are arranged through the straight duct pieces, an insulating stand is placed axially outside the shield ring, and a winding that fixes both windings, the shield ring, and the insulating stand from the axial direction. In the winding end insulation structure of a gas insulated transformer equipped with a support fitting, the axial position of the straight duct piece disposed between the insulating cylinders is limited between the low voltage winding and the high and low voltage windings. A wire device for disconnecting winding ends of a gas insulated transformer.
