Abstract
Способ определения остаточного ресурса асинхронного электродвигателя, при котором измеряют ток холостого хода, коэффициент мощности, активные сопротивления обмоток при постоянном токе, активные сопротивления изоляции обмоток и используют измеренные параметры в качестве влияющих факторов в системе нечеткой логики, отличающийся тем, что измеряют температуру обмоток статора, коэффициент поляризации, коэффициент абсорбции, величину воздушного зазора между статором и ротором, оценивают состояние подшипников качения и осуществляют акустическую диагностику изоляции статора, нормализуют четкие влияющие факторы для приведения к одному диапазону их изменения по формуле:K=(((Z+Z)/2)-K)*(-100/(((Z+Z)/2)-Z)),где K- значение влияющего фактора, приведенное к диапазону от -100 до 100;K- измеренное значение влияющего фактора;Z- минимальная граница изменения измеренного влияющего фактора;Z- максимальная граница изменения измеренного влияющего фактора, и настраивают диапазон изменения остаточного ресурса асинхронного электродвигателя в системе нечеткой логики так, что в конце скрипта conc с учетом округления round устанавливают следующую зависимость:Q=round((Q-Q)·T/(Q-Q)),где Q - остаточный ресурс асинхронного электродвигателя в годах;T - максимальный срок службы асинхронного электродвигателя (лет);Q- текущее значение остаточного ресурса асинхронного электродвигателя;Q- значение остаточного ресурса асинхронного электродвигателя при наихудших значениях влияющих факторов;Q- значение остаточного ресурса асинхронного электродвигателя при наилучших значениях влияющих факторов.A method for determining the residual life of an induction motor, in which the open circuit current, power factor, active resistance of the windings at constant current, active insulation resistance of the windings are measured and the measured parameters are used as influencing factors in a fuzzy logic system, characterized in that the stator winding temperature is measured, polarization coefficient, absorption coefficient, the size of the air gap between the stator and the rotor, assess the condition of the rolling bearings and carry out the akus diagnostic diagnostics of stator isolation, clear influencing factors normalize to bring them to the same range of change according to the formula: K = (((Z + Z) / 2) -K) * (- 100 / (((Z + Z) / 2) - Z)), where K is the value of the influencing factor, reduced to a range from -100 to 100; K is the measured value of the influencing factor; Z is the minimum border of the measured influencing factor; Z is the maximum border of the measured influencing factor, and the range of the residual asynchronous motor resource in a fuzzy logic system so that at the end of the script conc, taking into account the environment round coals establish the following relationship: Q = round ((QQ) · T / (QQ)), where Q is the residual life of the induction motor in years; T is the maximum service life of the induction motor (years); Q is the current value of the residual life of the induction motor ; Q is the value of the residual life of the induction motor at the worst values of the influencing factors; Q is the value of the residual life of the asynchronous motor at the best values of the influencing factors.
