Zusammenfassung:The utility model relates to a generator rotor winding turn-to-turn short circuit monitoring device. The generator rotor winding turn-to-turn short circuit monitoring device comprises a gap flux detector, a signal conditioning box, a signal conversion device, a judgment module and an alarm circuit, the signal conditioning box is provided with a first signal conditioning circuit and a second signal conditioning circuit; the output end of the air gap flux detector is electrically connected with the input end of the first signal conditioning circuit; the input end of the second signal conditioning circuit is connected with an active power signal and a reactive power signal of the generator; the first signal conditioning circuit and the second signal conditioning circuit transmit the adjusted and filtered signals to the judgment module through the signal conversion device for turn-to-turn short circuit judgment; and after the turn-to-turn short circuit is judged, the signal is transmitted to the alarm circuit to
