Наружная изоляция является одним из наиболее повреждаемых элементов высоковольтного оборудования. Изменения климата, экологии оказывают на ее состояние все больше воздействие. Доля отключений воздушных линий электропередачи (ВЛ) из-за загрязнений варьируется в зависимости от региона и конкретных условий эксплуатации, но в среднем она может составлять от 20% до 40% всех аварий на ВЛ. В регионах с высоким уровнем промышленного загрязнения или вблизи морских побережий эта цифра может достигать 50% и более. Основные причины отключений связаны с накоплением загрязнений на изоляторах, что приводит к перекрытию во влажных условиях. Наибольшее влияние атмосферные осадки, такие как моросящий дождь, туман или роса, оказывают именно в сочетании с различными твердыми проводящими частицами, оседающими на поверхности изолятора из воздуха, и образующими слой поверхностного загрязнения. Методы диагностирования изоляции различны, включая тепловизионный. ЦЕЛЬ. Изучение влияния увлажнения загрязненной поверхности стеклянных и полимерных изоляторов на их температуру в лабораторных условиях и оценка возможности диагностирования загрязнённого состояния. МЕТОДЫ. Для достижения поставленной цели было проведено тридцать лабораторных экспериментов с подвесными стеклянными и полимерными изоляторами в климатической камере (камере тумана) со снятием термограмм, контролем тока утечки и степени загрязнения. В ходе экспериментов менялись степень и способ загрязнения, условия увлажнения. РЕЗУЛЬТАТЫ. В ходе лабораторных исследований было показано, что тепловизорами можно диагностировать даже легко загрязненную изоляцию в смоченном состоянии. Среднее и среднеквадратичное значения температурных контрастов в большей степени зависят от уровня загрязнения (засаленности), чем от степени равномерности нанесения загрязнения. Предложена методология построения системы контроля изоляции на ВЛ и алгоритм автоматизированной обработки данных.</p></abstract><trans-abstract xml:lang="en"><p>ACTUALITY. External insulation is one of the most damaged elements of high-voltage equipment. Changes in climate, ecology have an increasing impact on it’s condition. The proportion of overhead transmission line (OTL) outages due to pollution varies by region and specific operating conditions, but on average it can range from 20% to 40% of all OTL failures. In regions with high levels of industrial pollution or near sea coasts, this figure can reach 50% or more. The main causes of outages are related to the accumulation of contaminants on insulators, which leads to overtopping in wet conditions. It is precipitation such as drizzle, fog or dew that has the greatest impact, combined with various solid conductive particles deposited on the insulator surface from the air, and forming a layer of surface contamination. Methods for diagnosing insulation are various, including thermal imaging. OBJECT. To study the effect of wetted contaminated surface of glass and polymer insulators on their temperature under laboratory conditions and to evaluate the possibility of diagnosing the contaminated condition. METHODS. Three dozen laboratory experiments with suspended glass and polymer insulators in a fog chamber with thermograms, control of leakage current and degree of contamination were carried out to achieve the goal. During the experiments, the degree and method of contamination and humidification conditions were changed. RESULTS. In the course of laboratory studies it was shown that thermal imaging cameras can diagnose even lightly contaminated insulation in the wetted state. The mean and rms values of temperature contrasts depend more on the level of contamination (greasiness) than on the degree of uniformity of contamination application. The methodology of construction of the insulation control system on overhead power lines and the algorithm of automated data processing are proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>воздушные линии электропередачи</kwd><kwd>подвесные изоляторы</kwd><kwd>термограммы</kwd><kwd>увлажнение изоляции</kwd><kwd>диагностика загрязнения тепловизором</kwd><kwd>температурные контрасты</kwd><kwd>лабораторные исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>overhead power lines</kwd><kwd>suspended insulators</kwd><kwd>thermograms</kwd><kwd>insulation wetting</kwd><kwd>thermal imaging fouling diagnostics</kwd><kwd>temperature contrasts</kwd><kwd>laboratory tests</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Research Provided Insight into Unexplained Line Outages [Электронный ресурс] // INMR [Сайт].
