Zusammenfassung:The invention provides a generator air brake air leakage fault detection method, and relates to the field of generator air brake fault detection. According to the generator air brake air leakage fault detection method, the time of 24 air brake blocks from input to quit during shutdown is obtained through an existing position sensor of a water-turbine generator set and a computer connected with the position sensor, then the input and quit time T of the air brake is calculated according to the obtained input and quit time of the air brake, and the air leakage fault of the air brake is detected. And then drawing the commissioning and retreating time calculated in the step S1 into a graph table. By collecting the switching time of the wind brake in the shutdown process in real time, calculating the switching time and drawing a change curve, personnel can know the operation condition in time, formulate treatment measures, improve the stability of the unit shutdown process, prolong the service life of equipment and
