Claims

[Scope of utility model registration request]

(1) A non-formed insulating barrier in the form of a flat plate to divide the oil gap in the radial direction between the outer peripheral surface of the cylindrical transformer winding whose terminals the high voltage rectifier is connected to and the ground metal body. A transformer for a high-voltage rectifier, characterized in that a rod-shaped insulator is attached along the axial direction so as to closely protrude toward the winding side near both circumferential ends of the insulation barrier. insulation structure.

(2) Utility model registration Claim 1 The feature is that the rod-shaped insulator is made of laminated presspods, and the cross-sectional shape of the portion protruding toward the winding wire is uniform in the axial direction. Insulation structure of transformer for high voltage rectifier.
