Abstract:Magistrsko delo obravnava področje napovednega vzdrževanja pri nadzoru naprav visokih napetosti in velikih tokov. Predstavljene so metode nadzora vibracij, nadzora olj in analize obrabnih delcev, uporaba infrardeče termografije ter metode merjenja in analize električnega toka močnejših elektromotorjev pri nadzoru naprav visokih napetosti in velikih tokov. Teoretično in z meritvami na konkretnem primeru sta podrobneje predstavljeni uporaba infrardeče termografije pri nadzoru energetskih transformatorjev in detekcija poškodb rotorjev asinhronskih elektromotorjev med obratovanjem. Podane so analize rezultatov, ugotovljene pomanjkljivosti merilnih metod, ugotovljene nevarnosti iz področja varstva pri delu in podani so predlogi za izboljšave.

Title:PREDICTIVE MAINTENANCE AT SURVEILANCE OF HIGH VOLTAGE AND LARGE CURRENT DEVICES
Abstract:Master work deals with tne Predictive maintenance methods at surveilance of high voltage and large current devices. Mechanical vibrations measurements and analysis, oil analysis and wear particle analysis, use of infrared thermography and induction motor current analysis are represented. The use of infrared thermography at surveilance of power transformers is shown. With teoretical background and with practical examples detection of multiple cracked rotor bars are represented. On practicle examples the measurements results are discused. Weakneses of Predictive maintenance methods and risk in occupational safety and sugestions for improvements were made.
Keywords:predictive maintenance, high voltage devices, infrared thermography, FFT analysis
