  • Patent number: 6538339
    Abstract: A power generation system (40) including an interchangeability component connecting device is provided. The system preferably includes an outer housing (60), an inner housing (50), a power generator (70), interchangeable main and neutral leads (102, 116), main side (84) and neutral side (94) current transformers assembled on the respective main and neutral leads, and lead connector interfaces (130, 140) having a plurality of lead connectors (135, 145) are provided. The lead subassemblies (80, 90) preferably include lead subassembly platforms (82, 92) having main leads (102) with main side current transformers (84) and neutral leads (116) with neutral side (94) current transformers positioned thereon The main (102) and neutral (116) leads are interchangeably connected to first (72) and second (74) side portions of the power generator (70).
    Type: Grant

  • Patent number: 5373211
    Abstract: A support assembly for the end windings of a turbine generator includes a plurality of braces which are spaced apart around the circumference of the winding basket and which are mechanically connected to support rings disposed around the stator coils. The support assembly is decoupled from the stator core such that the end windings and end winding support structure float freely of the stator core during normal generator operating conditions. During abnormal short circuit operating conditions, the support assembly contacts brackets on the stator core such that the end windings are slidably engaged upon and supported by the stator core. Radial clamps tightly secure the top and bottom coils to the end winding support assembly to apply radial compressive load to the coils to prevent radial displacement of the coils and to maintain the end winding-end winding support structure as a monolithic structure capable of withstanding abnormal operating conditions.
