Abstract

1395461 Supporting end windings in dynamoelectric machines KRAFTWERK UNION AG 26 June 1973 [26 June 1972] 30420/73 Heading H2A In a turbogenerator end winding support system, conductor bars projecting from a stator 1 are bent away from the axis and are helically wound in two layers 11, 12 into a frusto-conical form, and are supported by a ring 4 which is slidably mounted within a support defined by a series of arms 6 fixed to a stator pressure plate 3; limited axial displacements due to thermal expansion can thus be accommodated. In the arrangement shown, the conductor bars (three shown in each layer) are strapped to the ring 4 by means of a series of abutting cover plates 10 and a set of bolts 9, the layers 11, 12 being spaced by further plates 13. Cushions of deformable heat-hardenable material 30, e.g. resin, are included in the structure during assembly whereby spaces between the bars and plates may be filled after assembly merely by applying heat. A ring system 7 for cooling liquid or gas is also provided, this being joined to the coolant connection chambers 32 of the individual bars by flexible pipes 8.
