(INSTRUMENTATION OF MEASURING SYSTEMS FOR TECHNICAL DIAGNOSTICS OF ELECTRIC DRIVE EQUIPMENT)
В статье рассмотрены решения по построению измерительных систем для организации контроля технического состояния оборудования, в том числе насосного, вентиляторного, компрессорного с электроприводом на базе асинхронных электродвигателей. Применяемым методом диагностики является анализ амплитудных спектров токов и напряжений цепи питания электродвигателя.
Предложены компоновки измерительных систем диагностики как с ограниченными возможностями оценки основных видов неисправностей в узлах оборудования по спектру тока одной из фаз линии питания электродвигателя, так и с расширенным функционалом спектрального анализа сигналов токов и напряжений трех фаз двигателя с возможностью выявления большего количества повреждений в узлах и уточнения диагностических параметров в условиях их искажений частотными составляющими напряжения сети.
The article discusses solutions for the construction of measuring systems for organizing the control of the technical condition of equipment, including pumping, fan, compressor with an electric drive based on asynchronous electric motors. The diagnostic method used is the analysis of the amplitude spectra of currents and voltages of the electric motor power supply circuit.
The layouts of measuring diagnostic systems are proposed both with limited possibilities for assessing the main types of faults in equipment nodes according to the current spectrum of one of the phases of the electric motor power line, and with extended functionality for spectral analysis of current and voltage signals of three motor phases with the possibility of detecting more damage in the nodes and clarifying diagnostic parameters under conditions of their distortion by the frequency components of the mains voltage.
