摘要： A winding structure for a transformer has a first support having a central axis, and a second support also having a central axis. The second support is positioned having its central axis generally in-line with the central axis of the first support. The winding structure also has a winding which is wrapped around at least a portion of the first and second supports. The supports are tubular and are provided for at least supporting the winding. A method of making the transformer includes the steps of providing a mounting apparatus, and mounting a first support having a central on the mounting apparatus. The method also includes mounting a second support having a central axis on the mounting apparatus, wherein the second support is mounted on the mounting apparatus with its central axis mounted generally in-line with the central axis of the first support. In addition, the method includes winding a conductor around at least a portion of the first and second supports to form a winding.

摘要： A dry type, air cooled transformer having a mitered magnetic core and a compression bonded coil. In the disclosed embodiment, the magnetic core comprises a plurality of stacked lamination layers wherein each layer comprises a plurality of grain-oriented laminations wherein the ends of most of the laminations are mitered thereby resulting in joints between the leg and yoke pieces oriented at an angle to the favored magnetic directions of the adjoining laminations. The coil on each of the core legs is generally rectangular in shape and comprises a plurality of layers of wound conductor with the conductor layers in the end portions of the coil being spaced apart to form a plurality of air ducts for the passage of cooling air therethrough. The conductor layers in each of the side portions of the coil are compressed and then bonded together in their compressed state by means of a heat cured adhesive coated on opposite sides of the sheets of insulation between adjacent layers. This compression bonding of the coil sides squares up the inner and outer surfaces of the coil so as to improve the coil and core space factors thereby allowing a smaller core. Conversely, compression bonding allows higher output power ratings to be achieved by packing added conductor material through the same size core window. The compression bonding of the coil also permits duct spacers in the corners of the end ducts to be eliminated so that the duct spacing can be achieved by a single duct spacer located in the center portion of each duct thereby resulting in better conduction of heat from the coil sides to the ducted end portions of the coil.

摘要： The method making a dry type, air cooled transformer having a mitered magnetic core and a compression bonded coil with air ducts formed in the end portions of the coil. The coil on each of the core legs is generally rectangular in shape and comprises a plurality of layers of wound conductor with the conductor layers in the end portions of the coil being spaced apart to form a plurality of air ducts for the passage of cooling air therethrough. The conductor layers in each of the side portions of the coil are compressed and then bonded together in their compressed state by means of a heat cured adhesive coated on opposite sides of the sheets of insulation between adjacent layers. This compression bonding of the coil sides squares up the inner and outer surfaces of the coil so as to improve the coil and core space factors thereby allowing a smaller core. Conversely, compression bonding allows higher output power ratings to be achieved by packing added conductor material through the same size core window. The air ducts in the coil are formed by inserting temporary and permanent duct spacers in the coil during winding thereof, wherein the temporary duct spacers are located at the corners of the conductor layers. Following winding, the temporary duct spacers are loosened and removed from the coil thereby leaving only the permanent duct spacers in place.

摘要： A fuse housing for an oil-cooled transformer that uses a stopper to prevent oil from escaping the transformer tank as the fuse and fuse holder are removed. During normal operation, the stopper is held in an open position by the fuse holder. When the fuse and fuse holder are removed, the stopper closes and seals the upper end of the holder, preventing oil from draining through the upper portion of the fuse housing and escaping from the transformer tank.
