Opisany rezul'taty prakticheskoy teplovizionnoy diagnostiki zhelezobetonnyh opor kontaktnoy seti zheleznodorozhnogo transporta s prodol'nym i poperechnym raspolozheniem armatury. Teplovuyu stimulyaciyu osuschestvlyali s pomosch'yu induktora moschnost'yu 10 kVt, temperaturu registrirovali teplovizorami FLIR-P65 i Testo-875. V bezdefektnyh oporah otmecheno kontrastnoe proyavlenie skrytoy armatury v vide harakternyh temperaturnyh otpechatkov. Elektrokorrozionnoe razrushenie okolofundamentnoy chasti opor proyavlyalos' lokal'nym snizheniem temperatury i zamedleniem skorosti izmeneniya temperatury. Dannye teplovizionnoy diagnostiki sravnivali s rezul'tatami vizual'nogo i akusticheskogo kontrolya.
teplovoy kontrol', zheleznodorozhnye elektricheskie opory, induktivnyy nagrev, chislennoe modelirovanie
