Claims

[Scope of utility model registration request]

A plurality of disc windings are arranged between the inner and outer insulating cylinders, and a plurality of horizontal spacers are interposed between each of the disc windings to form a plurality of horizontal cooling passages radially. A plurality of vertical spacing pieces are interposed between the insulating cylinder and the disc winding to communicate with the horizontal cooling passage to form a plurality of inner and outer vertical cooling passages, and these inner and outer vertical cooling passages are alternately blocked. In electrical equipment windings in which a blocking plate is inserted into a horizontal cooling path to cause insulating fluid to flow in a zigzag pattern, the inner circumferential side of the blocking plate that blocks the inner vertical cooling path and the outer circumferential side of the inner insulating cylinder are tightly attached. At the same time, the outer diameter of the closing plate is made smaller than the outer diameter of the disk winding, and the outer circumferential side of the closing plate that closes the outer vertical cooling path is brought into close contact with the inner circumferential side of the outer insulating cylinder, and the inner diameter of the closing plate is made smaller than the outer diameter of the disk winding. is an electrical equipment winding characterized by having a larger inner diameter than the disc winding.
