ROTOR OF SALIENT-POLE SYNCHRONOUS MACHINE Russian patent published in 1995 - IPC

FIELD: electromechanical engineering. SUBSTANCE: rotor has pole core carrying field windings. Field coils have terminal strips 3 for their electrical connection. Terminal strips 3 are interconnected by flat tinned bars 4 at butt-end portions of coils. Buses 4 may be also of flexible type. Bolts 5 are used to connect strips 3 to buses 4. Same bolts are also used to secured all interpole links to holder. Strips 3 and buses 4 are locked in position upon connection by means of holder to prevent their displacement during hydraulic-turbine generator running. Top part 7 of holder equals in length bus 4 in tangential direction and has slot 7 throughout this length and stop 9 for locking insulating cleat 10 which is also equal in length to bus 4 and, in its turn, holds bus 4 in position by means of its slot 11 and stop 12. Insulating bushes 13 and cleats 10, 14 serve to insulate strip-to-bus joints from holder. Bottom part of holder is fixed at ends of studs 16 on rotor rim. Holder may be secured by other method. EFFECT: improved reliability of fixation of interpole connections. 2 dwg
