Abstract

V diplomskem delu je predstavljen problem staranja izolacije statorskih navitij in ocenjevanje njihove življenjske dobe ter izdelava merilnega mesta za preizkušanje pospešenega staranja izolacije statorskih navitij in izvedba meritev. V prvem delu naloge je podrobneje predstavljen postopek pospešenega staranja izolacije navitij električnih strojev in postopki ugotavljanja predvidene življenjske dobe pri izpostavitvi standardiziranim obremenitvenim testom. Največji poudarek je na termični obremenitvi oziroma stresu za katerega je tekom diplomskega dela prestavljen postopek izvedbe tovrstnega testa ter nadgradnja prvotnega merilnega mesta z izdelavo novega bolj funkcionalnega, ki uporabniku omogoča prijaznejšo in predvsem varnejšo uporabo pri preizkušanju. V osrednjem delu diplomske naloge je opisan celoten postopek zasnove, izdelave in nadgradnje novega merilnega mesta. Predstavljen je izris vezalnih shem električnih omar in izdelava uporabniškega vmesnika potrebnega za upravljanje. Podrobno je opisana tudi končna izdelava ter postavitev sestavnih delov merilnega mesta. V zaključnem delu diplomske naloge so podani še rezultati meritev termične obremenitve statorskih navitij, opravljene v termični komori merilnega mesta.

Secondary title: Measuring device for accelerated aging of electrical machines stator winding insulation
Secondary abstract: This diploma thesis presents the problem of the electrical machine stator winding insulation aging and their service life, as well as the production of a measuring equipment for testing the accelerated aging of the winding insulation. The first part of the work deals with the accelerated aging of the winding insulation of electrical machines and the procedures for the machine lifetime prediction after the exposure to the standardized stress tests. The most important emphasis is on thermal stress tests, for which the original measuring equipment has been considerably upgraded in order to enable a more user-friendly and safer device. The entire process of designing, construction and upgrade of the new measuring equipment is described in the central part of the thesis. In addition, the drawings of the wiring diagrams of electrical cabinets, the design of the user interface required for the equipment management and the final device assembly are presented in detail. Finally, the measurements of the thermal stress test were performed with the new measurement equipment on the real machine stator insulation windings.
