  • Bus duct assembly for high-power rotary current transformer system
    Patent number: 6753634
    Abstract: A rotary transformer system (20) comprises a rotatable shaft (28) having at least one and preferably plural electrically conductive slip rings (27) mounted thereon. The slip rings (27) of the phase planes are electrically connected to their respective windings on rotor assembly (22) by the bus conductors (80). The bus conductors (80) extend through respective phase isolated bus ducts (82) formed interiorly in rotatable shaft (28). The bus ducts (82) have a buffer (146) provided therebetween so that the bus ducts (82) are not in physical contact, but are spaced apart and separated. A mouth (160) and annulus (162) of each bus duct (82) extend through a cover plate (164). The cover plate (164) is secured by fasteners (166) through insulated spacers (167) and is held slight aloft above the circumference of rotatable shaft (28), thereby insulating cover plate (164) from rotatable shaft (28). The cover plates (164) of adjacent bus ducts (82) are electrically connected by a flux plate (170).
