摘要： A seal is provided at the intersegments of hydrogen seal rings for preventing oil leakage through this potential gap between the seal ring segments. By minimizing leakage through the gaps between the open rings, hydrogen consumption in hydrogen-cooled generators due to leakage oil is reduced. In a preferred embodiment, the seal is provided by a brush seal secured to one of the seal ring segments and received in a slot defined in the other of the seal ring segments.

摘要： A generator gas shield includes an annular ring body having an outer radially extending flange terminating at a first free end of a first diameter; a curved inlet portion; a substantially axial portion surrounding a center opening, and a curved outlet portion terminating at a second free end of a second diameter smaller than the first diameter.

摘要： A ventilation pathway for a cooling gas to flow extends on a radial axis in a generator stator core. The ventilation pathway comprises at least two magnetic laminations and a plurality of space blocks extending radially in the generator stator core. The space blocks are fastened and disposed between the magnetic laminations. At least one of the space blocks includes a wavy longitudinal profile that includes an alternating pattern of peaks and valleys with respect to the radial axis of the generator stator core. Alternatively, at least one of the space blocks has a plurality of protrusions defining a pattern of peaks and valleys extending from a sidewall of the space block. Several different shapes of vortex generators are punched in the lamination are located within the ventilation pathway.

摘要： A magnetic armature wedge is provided for replacing conventional dovetail wedges in high-powered large-size turbine generators. The magnetic armature wedges that are used for supporting the armature bars are made by molding resin, e.g., epoxy with ferromagnetic particles, wires, laminates and the like embedded therewithin. The magnetic particles, wires, laminates and the like increase the magnetic permeability of the wedges causing higher slot flux leakage and high generator subtransient reactants.
