Technical Field
The invention belongs to the technical field of power transformer manufacturing, and particularly relates to a roller shoe for bonding an oil duct stay.
Background
The oil duct arranged in the transformer coil reduces the temperature of the coil by utilizing the convection action of transformer oil, thereby improving the heat radiation performance of the coil winding. The oil duct stay curtain is formed by uniformly adhering oil duct stays with rectangular cross sections on the adhesive tape, and is used for preventing the oil duct from being blocked when the coil is pressed. The strip direction of the oil duct stay is called the length of the oil duct stay, the length of the rectangle of the cross section is called the width of the oil duct stay, and the width of the cross section is called the thickness of the oil duct stay. The industry standard specifies that the surface adhered with the dispensing paper is one of two surfaces formed by the length and the width of the oil duct stay. The width and the thickness are less different, such as 6mm in width and 5mm in thickness, so that the width and the thickness are difficult to distinguish when the mechanical bonding is carried out.
