Abstract
Способ диагностики технического состояния силового электрооборудования, включающий запись зависимостей от времени напряжения и тока, потребляемых электродвигателем, выполняемую с помощью датчиков напряжения и тока с последующим пропусканием через фильтр низких частот, отличающийся тем, что производят вычисление мгновенных мощностей каждой фазы, выполняют спектральный анализ полученных сигналов напряжения, тока и мощности, рассчитывают коэффициенты несимметрии (тока, напряжений, мощности), коэффициенты гармоник (тока и мощности), коэффициент потерь мощности, на основе которых, с учетом текущего задания выходной координаты, определяют техническое состояние электропривода и оценивают остаточный ресурс. A method for diagnosing the technical condition of power electrical equipment, including recording the dependences of time on the voltage and current consumed by the electric motor, performed using voltage and current sensors, followed by passing through a low-pass filter, characterized in that the instantaneous powers of each phase are calculated, and spectral analysis of the received signals is performed voltage, current and power, asymmetry coefficients (current, voltage, power), harmonic coefficients (current and power) are calculated, ffitsient power loss, on the basis of which, taking into account current job output coordinates define the technical condition of the actuator and estimate the remaining service life.
