Abstract: PURPOSE: To easily manufacture a device for holding a winding end part and economically, which can withstand all stresses generated at the time of operation and can be refitted, if looseness occurs. CONSTITUTION: The end part of a stator holding winding consisting of upper and lower bars 5, 6 is supported by an outer ring 10, and the outer ring 10 is supported by a bracket 8. The intervals of the upper and lower bars are maintained by a pressurizing hose 13 which is filled with a synthetic resin. The bars 5, 6 are tightened by an inner ring 15. The inner ring 15 is constituted of a closed inside conical ring 15a, a ring 15a of multiple portions, and a supporting segment 15c.

Abstract: PURPOSE: To withstand all operating load with good reliability and to perform following tightening, when the coupling of a coil head is loosened by providing a tightening means between the inner facing surface of a supporting bracket and a turn end. CONSTITUTION: For a stator compressing plate 3, a second outer ring 27 is mounted on a shoulder 20, which is, provided at the outer surface at the opposite side of a stator mounting iron core 2. A stator-mounting spring means 32 is arranged between the end surface of the second outer ring 27 on the side of the stator mounting iron core and a surface 31 of the shoulder 26 of the stator compressing plate 3 extending to the radial direction of the holder 26 and uniformly distributed along the entire circumferential direction. Then, the second outer ring 27 is fixed to a bracket 7 with a bolt 37, and a first outer ring 9 is fixed to the second outer ring 27 with a tie-bolt 38. As a result, the coil-head structure, that is strong against vibrations is obtained by the combination of the arrangement and fixing of both rings, and an inner ring and the tightening means. Therefore, the device can withstand all operating loads with good reliability, and the following tightening can be performed, when the coil head is loosened at the same time.

Abstract: PROBLEM TO BE SOLVED: To avoid intricate shrink fit between a turbo generator and a steam turbine without increasing the overall length of a turbine generator. SOLUTION: In a thermal power station where a single turbo generator is driven commonly by a gas turbine and a steam turbine, slip rings 8, 9 are arranged on an independent slip ring shaft 14 coupled with the essential shaft 10 of an electric machine through a first separable coupling 11. The slip ring shaft 14 is provided, at the end part thereof remote from the electric machine, with a coupling flange 15 which is coupled with the slip ring shaft 14, by welding, only after applying the slip rings 8, 9 to the slip ring shaft 14.

Abstract: PURPOSE: To protect an excitation coil from relative movements in the axial direction by installing, between an insulating strip and the excitation coil, a parallel and elastic strip-like intermediate layer and fitting a pair of downward projections of the intermediate layer in cutouts formed in the insulating strip. CONSTITUTION: An excitation coil, constituted of hollow conductors 1a, 1b, 1c, 1d, is located in a slot 2 of a rotor body 3. The slot 2 is closed by a slot wedge 4. Between the uppermost hollow conductor 1a and the slot wedge 4, a wedge dunnage 5 made of insulating material having resiliency is located. Furthermore, in the bottom of the slot, an insulating strip 6 is installed. Between the insulating strip 6 and the lowermost hollow conductor 1d, a charging strip 7 is located. Thus, the elastic intermediate layer can be fixed in the axial direction by a simple means. Furthermore, the intermediate layer can be manufactured at a low cost with all the requirements for operation being satisfied without damaging the path of a cooling gas.
