20.500.12556/RUL-187270 Sanacija generatorja po izlitju hladilne vode v njegovo ohišje Generator refurbishment after cooling water leakage into its housing Diplomsko delo obravnava sanacijo generatorja 1 v Termoelektrarni Toplarni Ljubljana po vdoru hladilne vode v njegovo ohišje. Med remontom je bila ugotovljena poškodba hladilne cevi, zaradi katere je prišlo do prisotnosti vode in vlage v notranjosti generatorja ter do korozijskih poškodb posameznih delov. V delu je prikazan potek sanacije od demontaže in pregleda generatorja do čiščenja, sušenja, obnove poškodovanih delov in ponovne montaže. Posebej so obravnavani rotor, stator, ležaji, hladilniki in drenažni sistem. Predstavljeni so tudi postopki kontrolnih meritev, ki se izvajajo za oceno stanja generatorja. Na primeru generatorja 3 so prikazane meritve izolacijske upornosti, faktorja polarizacije, faktorja dielektričnih izgub, kapacitivnega toka, delnih razelektritev in lastnih frekvenc ventilatorskih lopatic. Rezultati prikazanih meritev kažejo na ustrezno stanje preverjenih delov generatorja in poudarjajo pomen kontrolnih meritev pri potrjevanju kakovosti izvedenih vzdrževalnih del. This thesis deals with the repair and refurbishment of Generator 1 at the Ljubljana Combined Heat and Power Plant following the ingress of cooling water into the generator housing. During the overhaul, a damaged cooling tube was identified, which caused water and moisture to enter the generator and resulted in corrosion damage to several components. The thesis presents the complete repair process, from disassembly and inspection of the generator to cleaning, drying, refurbishment of damaged components, and final reassembly. Particular attention is given to the rotor, stator, bearings, coolers, and drainage system. Diagnostic and verification measurements used to assess the condition of the generator are also presented. Using Generator 3 as an example, the thesis includes measurements of insulation resistance, polarization index, dielectric dissipation factor, capacitive current, partial discharges, and the natural frequencies of the fan blades. The presented measurement results indicate that the inspected generator components were in satisfactory condition and highlight the importance of diagnostic measurements in verifying the quality of the maintenance and overhaul work performed. generator sanacija remont hladilni sistem izolacija kontrolne meritve generator repair refurbishment overhaul cooling system insulation diagnostic measurements true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-09 15:00:01 2026-09-09 15:00:05 2026-09-11 03:42:09 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 63456 Smolnikar_Jakob_-_Sanacija_generatorja_po_izlitju_hladilne_vode_v_njegovo_ohisje.pdf Smolnikar_Jakob_-_Sanacija_generatorja_po_izlitju_hladilne_vode_v_njegovo_ohisje.pdf 1 04EAF10A00D29EDA709BA815DD5C7CF6 9419e1c34af0f51c348906ce2b57added695a72f5efe2a92aa82a611d7d8b858 5b18b78c-ac4e-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246818 Fakulteta za elektrotehniko 0 0 0
