PROCESS CONTROLLING RATE OF GROWTH OF TURN-TO-TURN SHORT-CIRCUITS IN WINDING OF ROTOR OF ELECTRIC MACHINE (VARIANTS)

摘要

FIELD: electrical engineering; operation and repair of turbogenerators of high-power power units. SUBSTANCE: number of turn-to-turn short-circuits is determined on operating electric machine with the aid of known methods and gears. Diminished rate of development of fault is provided by change of current of rotor or temperature of environment of winding of rotor so that quantitative characteristics of turn-to-turn short-circuits acquire minimal value. EFFECT: minimum rate of growth of turn-to-turn short-circuits in winding of rotor of electric machine to ensure removal of fault during scheduled repair. 2 cl
