DEVICE FOR CONTINUOUS MONITORING AND CONTROL OF OPERATION EQUIPMENT OF POWER ELECTRICAL SUBSTATION UNDER CONDITIONS OF OPERATION

摘要

The technical solution relates to the field of measurement and control of equipment operating modes, therefore, it can be used to measure partial discharge signals and dielectric losses in the electrical insulation of live parts of three-phase high-voltage devices under operating voltage for the purpose of comprehensive diagnostics of defects and prediction of residual life with the possibility of regulating operating modes electrical equipment. A device for continuous monitoring and control of operating modes of electrical equipment power electrical substation in operating conditions, consisting of an active part in the form of a system of conductive, electrically connected elements that are under high voltage and surrounded by insulation layers, containing processing and recording partial discharge signal, and at least one partial signal pickup sensor discharges, switch, and probes connected to controlled devices and to the inputs of the switch, probes connecting the switch directly to measuring transformers bypassing capacitive castors, an analyzer of dielectric losses and capacities, an analog-to-digital converter, a microprocessor control unit, a thyristor frequency converter with a tunable topology, the output of the analyzer of dielectric losses and capacitance connected to the input of an analog-to-digital converter, the output of which is connected to the input of the microprocessor control unit, the outputs of which are connected to the input of the switch and the input of the thyristor frequency converter with a tunable topology. that when implementing the claimed solution acts more effective monitoring and management modes of electrical equipment. 1 ill.
