All-weather large-scale turbonator stator winding corona accurate positioning method

The invention provides an all-weather large-scale turbonator stator winding corona accurate positioning method, which is characterized by comprising steps of setting a gain of an UV detector as an appropriate value, arranging the UV detector at the position which is 3-4 meter away from the terminal part of the stator winding, observing the number of background quantum photons of the stator winding to be tested through the UV detector before voltage boosting of the stator winding, wherein the number of the background quantum photons is not greater than 100, executing rated wire voltage on the stator winding to be tested, observing the number of the corona quantum photons of the winding to be tested by the UV detector, and, meanwhile, clearly shooting and accurately positioning the corona. The invention discloses the all-weather large-scale turbonator generator stator winding corona accuracy positioning method, which is high in positioning accuracy, simple and efficient, direct and vivid, safe and convenient and does not affect the running of the device. The invention is applicable to the corona observation on the large scale generator stator winding, and is accurate, safe, simple, efficient and time saving.
