Nadzor novega TR412 KPT12 KPT (Siemens) 300/300/100MVA, 400/115/10,5kV v RTP Okroglo v garancijskem obdobju 2 let : ref. št. 1969Gradnik, Timotej ...V referatu so predstavljeni izsledki spremljanja novega transformatorja Siemens TR412 KPT (Siemens) 300/30011OOMVA, 400/115/1 0,5kV z vgrajenim sistemom neposrednega daljinskega nadzora, vgrajenem ... leta 2006v RTP Okroglo/ekom prvih dveh let obratovanja. Analizirano je delovanje treh novih elektronskih senzorjev (opticni temperaturni senzorji FISO senzorj za nadzor plinov volju Hydran ter senzor za nadzor vlage volju Vaisala), vkljucenih v sistem neposrednega daljinskega nadzora, kot tudi tocnost oz. ucinkovitost sistema neposrednega nadzora samega. Transformator je bil v dvoletnem obdobju periodicno nadzorovan tudi s preiskavami 12 vzorcev transformatorskega olja (plinska in tekocinska kromatografija in fizikalnokemijske preiskave olja). Izdelana je primerjava rezultatov, dobljenih na periodicno vzetih vzorcih, z rezultati elektronskih senzorjev vgrajenih v sistem neposrednega daljinskega nadzora. Rezultati meritev z opticnimi temperaturnimi senzorji za neposredno merjenje temperature najtoplejše tocke (hot-spot) so analizirani in primeljani z ostalimi temperaturnimi indikatorji ter izracunanimi temperaturami glede na rezultate preskusa segrevanja. Podrobnejša analiza temperaturnih razmer je obravnavana v EIMV referatu št. 1906. Rezultati meritev senzorja za nadzor plinov volju kot tudi senzorja za nadzor vlage volju kažejo na netocno delovanje obeh senzorjev. Vzroke za netocno delovanje opazovanih elektronskih senzorjev je mogoce pripisati vec tehnicnim dejavnikom. AvtOlji referata priporocajo, da se z dobaviteljem oz. proizvajalcem senzorjev izvede poglobljena strokovna diskusija o sedanjih ugotovitvah in možnostih za izboljšave delovanja njihovih naprav.Type of material - treatise, studyPublication and manufacture - Ljubljana : Elektroinštitut Milan Vidmar, 2009Language - slovenianCOBISS.SI-ID - 30468357
