Программно-аппаратный комплекс диагностики состояния электрических изоляторов на основе технического зрения

Abstract

Control of the equipment dielectric insulation is one of the most important types of diagnostics in operation of the electrical networks, because the defects cause ionization of voids and partial corona discharges. These discharges gradually destroy the insulation causing the energy loss, radio interference and decreasing the fire safety of the operated electrical equipment. Common failures of electrical insulators are breakdowns, overlaps and mechanical damage. The need to determine the resistance against the surface discharges increases in case of using the new polymer materials due to their characteristics. Developing the systems with computer (technical) vision is one of the ways for implementing automated control of the quantity and the area of corona discharges. The long-term experience of diagnostics accumulated by the specialists by using the ultraviolet flaw detectors and thermovision cameras has demonstrated the high efficiency in checking the damages in the high-voltage equipment and power lines. Application of vision technologies in the hardware and software complex will eliminate errors in checking and analyzing the flares, as well as minimize human participation in a number of monotonous operations, reduce the loss of working time caused by the human factor, protect the life and health of workers.
