Claims

[Scope of utility model registration request]

A disc winding is constructed by stacking a plurality of disc-shaped unit windings between an inner insulating cylinder and an outer insulating cylinder arranged concentrically via a horizontal oil pipe. In a structure in which a plurality of unit windings are partitioned and the interval between horizontal oil passages located above and below at least one unit winding is expanded than the interval between horizontal oil passages between other unit windings, the enlarged oil passage 3 in the vertical direction by two insulating collars each having a plane extending in the radial direction and having an inner and outer diameter that does not block the vertical oil channel formed between the disc winding and each insulating tube.
The oil-immersed transformer winding is characterized in that the enlarged horizontal oil passage is divided into upper and lower parts by wrapping a flow rate suppressing plate around the outer periphery of the horizontal oil passage between the insulating collars and blocking the horizontal oil passage. line.
