BRUSHLESS SELF-EXCITED SYNCHRONOUS GENERATOR Russian patent published in 2004 - IPC

FIELD: electrical engineering. SUBSTANCE: generator has additional stator winding for its excitation, voltage corrector, and built-in electronic protective system that functions to protect generator and its loads against accidents, to remotely disconnect load, and to memorize kind of accident causing disconnection of generator field. Independent-release field switch built in generator is connected to built-in electronic protective system. Independent-release load circuit breaker inserted in generator power circuit is connected to built-in electronic protective system. Off-time delay element is inserted in field switch circuit. Inserted in built-in electronic protective system is unit identifying and memorizing kind of accident causing disconnection of generator field. Auxiliary contact inserted in field switch is connected to kind-of-accident identifying and memorizing unit and at least one thermal relay is built in its bearings. EFFECT: enhanced reliability of generator protective system. 7 cl, 1 dwg
