摘要： A system and method for locating inter-turn short circuits or ground faults in a rotor winding of an electrical generator. The method analyzes data from a Recurrent Surge Oscillograph (RSO) test, identifies a spike or anomaly in a reflected RSO signal, determines an elapsed time between a transmitted signal and the anomaly in the reflected signal, calculates a distance along the winding conductor to the inter-turn short circuit or ground fault based on the elapsed time, and uses a geometric model of the winding conductor to identify a location of the fault based on the distance. The location of the inter-turn short circuit or ground fault specifies a coil number, a turn number within the coil and a position within the turn.

摘要： A locking arrangement for a row of radial entry blades (62) of a turbo-machine. A closing blade (66) includes a root portion (74) having an axial attachment shape (78) for engagement with an axially oriented slot having an axial attachment shape (76) formed at the entering slot location (34) of the radial entry rotor disk (56). For applications utilizing blades with curved platform faces (112), a preceding blade (108) and a following blade (110) in the row are designed with one curved face for abutting adjacent radial entry blades and one flat face (120) for abutting the flat closing blade faces (116). The closing blade (84) may be designed with a root portion (88) having two legs (90,92) that are urged apart by a key (86) into tight contact with the adjacent blades. A closing blade (62) substantially identical to the radial entry blades may be affixed in the entering slot location with a connecting member (96) that has a radially inner portion (98) having an axial attachment shape and a radially outer portion (100) having a radial attachment shape. A flaw in a perimeter portion of a radial entry rotor disk (56) may be repaired without welding by removing the flaw along with adjoining material to form an axial attachment shape in the rotor disk, and then installing closing blade with a complementary axial attachment shape into the repair location.

摘要： A centerline suspension arrangement (42) for a turbine (40). A turbine inner casing (44) is supported within an outer casing (46) via a support member (60) that includes an inner portion (62) contacting the inner casing and an outer portion (66) extending into a slot (68) formed in the outer casing. The support member is slid into an axially oriented slot (64) formed in the inner casing and is body bound therein with respect to radial movements, with the support member and the inner casing slot including opposed vertical support surfaces (82, 90) and a pair of oppositely facing opposed horizontal support surfaces (80, 88 and 86, 92). Thus, dead weight and operating loads from the inner casing are reacted through the support member and into the outer casing without the necessity for any bolting or other fastener attachment in the design load path between the support member and the inner casing.
