摘要： A three-phase non-linear dry-type transformer has integral molds formed of a glass fiber-reinforced polymeric material. The low voltage coil is comprised of an inner low voltage mold formed around each of the at least three core legs, a low voltage conductor winding wound upon the inner low voltage mold and an outer low voltage mold formed around the low voltage winding. The high voltage coil is comprised of an inner high voltage mold disposed around the outer low voltage mold, a high voltage conductor winding wound upon the inner high voltage mold, and an outer high voltage mold formed around the high voltage conductor winding. An annular space between the inner and outer high voltage molds and the inner and outer low voltage molds is filled by an insulating polymeric material during a casting process. The molds are bonded to the coil windings by the insulating polymeric material and remain during the operation of the non-linear transformer as integral components of the non-linear transformer.

摘要： Tap covers and projections for an electrical device are provided. The tap projections have bosses or taps raised from a surface of the tap projection and encapsulated with a resin except for an outer surface of the bosses or taps. The tap projections may have a channel or recess between individual bosses or taps to prevent degradation of the insulation between the respective adjacent bosses or taps. When a tap cover is provided, it is pushed on or bolted to the tap projection. The tap cover may be provided for an individual tap or an entire tap projection and may be formed of a resin or an elastomeric material. The tap cover has a first generally planar surface and a second generally annular surface having a circumferentially-extending groove on an inside surface. The circumferentially-extending groove is located slightly beneath the second generally annular surface. The groove of the tap cover is designed to fully engage with a raised lip of a tap projection or individual tap of a transformer. Another embodiment of the tap cover has openings to receive epoxy- headed bolts that are used to connect the tap cover to the tap projection through the tap connectors.

摘要： A three-phase non-linear transformer is cooled by first (30) and second fans (40). The first fan (30) is attached to the first core clamps (12) of the transformer using a first mounting structure (15). The second fan (40) is attached to the second core clamps (24) of the transformer using a second mounting structure (17). The first fan is positioned so that air is directed toward a central passage of the core. The second fan is positioned so that air is drawn through the central passage of the core. The first fan circulates air through a central passage in the transformer core and channels that exist between adjacent coil assemblies. The second fan draws air through the central passage and channels and further expels the air into the surrounding environment. The first and second fans are controlled by a control panel through which they are run automatically or manually.

摘要： A method of making a transformer core provides a plurality of amorphous material strips 10, 10'. The amorphous strips are wound to define a plurality of superposed layers 14, 14' of amorphous strips, each layer defining a core loop of the transformer. The winding step 1 ) provides at least a certain layer including interlaced, adjacent strips having differing widths thereby defining overall width of the certain layer to be greater than a width of the widest strip of the certain layer, and 2) ensures that a layer is in superposed relation with the certain layer.

摘要： A three step non-linear transformer core is formed from three sections of laminations each having different widths and cross-sectional areas. A first section of laminations is formed by cross-slitting a generally rectangular sheet or strip of metal. A resulting generally triangular segment is then wound upon a mold to form a first section of a core frame having a trapezoidal cross section. A second section of laminations is wound upon the first section of laminations to form a segment of a core frame having a rhombic cross section. The third section of laminations is wound upon the second section of laminations to form a segment of a core frame having a trapezoidal cross section. Each of the first, second, and third sections of laminations are offset from one another by a predetermined angle of offset.

摘要： A protective coating system for application to exposed surfaces of a transformer core prevents corrosion of the core. The protective coating is suitable for use in industrial and marine environments where many factors impact the life of the transformer core. The protective coating comprises at least three coating layers. The first coating layer is an inorganic zinc silicate primer. The second coating layer is a polysiloxane. The third coating layer is a room temperature or high temperature vulcanizing silicone rubber. A silicone rubber sealant may be further applied to outer edge surfaces of the core.
