Abstract

Способ определения места локализации и вида дефектов в активной части электрической машины, находящейся в рабочем режиме, основанный на регистрации высокочастотных сигналов, возникающих в результате разрядных явлений в элементах поврежденной изоляции, отличающийся тем, что на разные стороны наружной поверхности корпуса электрической машины устанавливают не менее четырех измерительных датчиков частичных разрядов, подключенных к регистрирующей аппаратуре, поочередно перемещают каждый из датчиков в пределах границ поверхности стороны корпуса, на которую он установлен, до получения на выходе датчика максимального сигнала, после чего датчик фиксируют на поверхности корпуса, причем после фиксации первого датчика следующие датчики фиксируют при условии совпадения формы их выходных сигналов с формой выходного сигнала первого датчика, которую запоминают с помощью регистрирующей аппаратуры, далее измеряют время запаздывания прихода принятых датчиками сигналов относительно первого принятого сигнала и по их величине определяют место локализации дефектного узла, а по форме выходного сигнала датчика судят о виде разрядного явления.A method for determining the location and type of defects in the active part of an electric machine in operating mode, based on the registration of high-frequency signals resulting from discharge phenomena in the elements of damaged insulation, characterized in that at least four are installed on opposite sides of the outer surface of the body of the electric machine partial discharge measuring sensors connected to the recording equipment, each sensor in turn moves within the boundaries of the surface of the side s of the case on which it is installed, until the maximum signal is received at the output of the sensor, after which the sensor is fixed on the surface of the case, and after fixing the first sensor, the following sensors are fixed provided that the shape of their output signals coincides with the output signal form of the first sensor, which is stored using recording equipment, then measure the delay time of arrival of signals received by the sensors relative to the first received signal and determine the location of the defective node by their value, and by The output signal of the sensor judges the type of discharge phenomenon.
