APPARATUS FOR JUDGING INSULATION DEGRADATION STATE OF ROTATING MACHINE

摘要

The present invention relates to an apparatus for judging an insulation degradation state of a rotating machine. The apparatus of the present invention estimates discharging amount of slot discharge by measuring and analyzing density and wind speed/temperature of an ozone gas using a sensor in air exhausted from the rotating machine, and therefore judges degree of insulation degradation to the estimated result and warns the insulation degradation to a manager; measures more accurate ozone density in the air by analyzing the ozone density included in the air by measuring the wind speed and the temperature and the ozone density influencing on density of the air exhausted from the rotating machine; senses the ozone gas by sampling the air absorbed through a sampling nozzle in an exhaust pipe to measure the ozone density accurately; and measures the ozone gas density according to the actual discharging amount to set a threshold for judging degradation of the rotating machine by using a calibration method, and sets the measured ozone gas density as the threshold.;COPYRIGHT KIPO 2016
