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： Encapsulating compositions for inductive devices have a polybutadiene base, predominate in trans-1,4 polybutadiene, and include cis-1,4 polybutadiene and vinyl-1,2 polybutadiene, together with an initiator, an inhibitor and a co-agent for improving the curing of the composition. The compositions are usable at higher temperatures, based on a conditioning of the composition during cure at or near the projected use temperature. When combined with high temperature conductor insulation coatings, such as polyimides, a high temperature soft cure encapsulation is achieved from which an inductive device may be liberated without damage to the device.

摘要： Improved encapsulating compositions for inductive devices are provided. The composition has a polybutadiene base and contains an initiator, an inhibitor and a co-agent for improving the curing of the composition under the influence of the initiator.Certain compositions are usable at higher temperatures than prior polybutadiene base encapsulating compounds based on a conditioning of the composition during cure at or near the projected use temperature. When combined with high temperature conductor insulation coatings, such as polyimides, a high temperature encapsulating system is achieved.Certain compositions are usable to provide a soft cure encapsulation from which an encapsulated inductive device may be liberated without damage to the device. For such compositions, soft curable polybutadienes are employed and particularly those having high trans and cis components.
