Claims

[Scope of utility model registration request]

A winding start high voltage shield provided on the primary winding form,
In a gas insulated transformer, which has a primary coil configured in a stratified manner on the high voltage shield at which the winding starts, the primary coil is connected between the lines of the line, and is housed in a sealed container filled with insulating gas, a large number of small The above-mentioned winding start high-voltage shield has a cylindrical part made up of a conductor plate with holes, and ring shields are attached to both ends of the cylindrical part, and the above-mentioned primary shield has a step on its outer circumferential surface and a thicker central part in contact with the high-voltage shield. The small hole reduces eddy current loss due to leakage magnetic flux of the primary coil in the cylindrical portion, and the step makes it possible to connect the outer side of the R part of the ring shield at both ends of the high voltage shield at the beginning of winding and the primary coil. A gas insulated transformer characterized by providing a gas space between the winding and the winding.
