    • A rotary transformer has a bus duct assembly that extends through the hollow shaft of a rotary transformer from collector or slip rings positioned above a drive motor for the rotary transformer to end windings of the rotor positioned most remote from the drive motor. By positioning the leads of the bus duct connection with the rotor end windings on the rotor end windings most remote form the drive motor, the shaft strength and integrity is not reduced due to the torque applied by the drive motor. Further, the shaft is formed from two coupled shaft sections and the bus duct assembly comprises two L shaped sections each positioned substantially within a corresponding shaft section. The bus duct sections are interconnected to complete the bus duct assembly making it simpler to remove the first or upper shaft section from the second or lower shaft section during field servicing. Further, the use of the two bus duct sections within the shaft coupled together simplifies assembly of each bus duct section within its corresponding shaft section.
    • 旋转变压器具有总线管道组件,其从位于驱动电机上方的收集器或滑环延伸穿过旋转变压器的空心轴,用于旋转变压器以将位于最远离驱动电机的转子的绕组端接。 通过将转子端绕组的总线管道连接的引线定位在最远距离的转子端绕组上形成驱动电机,由于驱动电机施加的转矩,轴的强度和完整性不会降低。 此外,轴由两个联接的轴部分形成,并且总线管道组件包括两个L形部分,每个部分基本上位于相应的轴部分内。 总线管道部分相互连接以完成总线管道组件,使得在现场维修期间更简单地从第二或下部轴部分移除第一或上部轴部分。 此外,使用连接在一起的轴内的两个总线管道部分简化了每个母线管段在其对应的轴段内的组装。

    • An electrical interconnection system (100) comprises a variable frequency rotary transformer (102) and a control system (104). The control system (104) adjusts an angular position of the rotary transformer (102) so that mesured power (P1) transferred from a first electrical system (22) to a second electrical system (24) matches an inputted order power (Po). The rotary transformer (102) comprises a rotor assembly (110) and a stator (112), with the control system (104) adjusting a time integral of rotor speed over time. The control system (104) includes a first control unit (107) and a second control unit (108). The first control unit (107) compares the input order power (Po) to the measured power (P1) to generate a requested angular velocity signal omega o. The second control unit (108) compares the requested angular velocity signal omega o to a measured angular velocity signal omega r of the rotary transformer to generate a converter drive signal (To) to a torque control unit (106), thereby controlling the angular positioning ( theta r) of the rotor assembly (110) relative to the stator (112). In various embodiments, the torque control unit (106) is integrated in the rotor assembly (110) and stator (112) of the rotary transformer (102).
