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.
