U specijalistikom radu su uvodno obrađena i opisana elektroenergetska postrojenja u sastavu Glavne hidroelektrane Vinodol (HE Vinodol, HE Rijeka i HE Gorski kotar) gdje su ugrađeni transformatori te njihova ulogu u sustavu. Nadalje, u radu je obrađen proces održavanja energetskih transformatora u pogonima koji su u sastavu Glavne hidroelektrane Vinodol. Dat je osvrt na zakone i pravilnike koji definiraju opseg, način i dijagnostiku na transformatorima, a iz kojeg proizlazi proces održavanja transformatora koji se primjenjuje. Obrađeni su i opisani postupci ispitivnja energetskih transformatora koji se primjenjuju na transformatore unutar pogona Glavne hidroelektrane Vinodol. Na kraju rada izdvojeno je nekoliko slučajeva kvarova na transformatorima i pripadajućoj opremi s analizom kvarova na način da su istraženi i obrađeni dostupni tehnički podatci, ispitni izvještaji i postupci na koji način su kvarovi riješeni. The paper introduces and describes the power plants within the Main Hydro Power Plant Vinodol (HPP Vinodol, HPP Rijeka and HPP Gorski kotar) where transformers are installed and their role in the system. Furthermore, the paper deals with the process of maintenance of power transformers in the plants that are part of the Main Hydro Power Plant Vinodol. A review is given of the laws and regulations that define the scope, manner and diagnostics of transformers, and from which the process of maintenance of the transformer is applied. Test procedures for power transformers applied to transformers within the Vinodol Main Hydro Power Plant have been processed and described. At the end of the paper, several cases of failures on transformers and related equipment with fault analysis were singled out in such a way that the available technical data, test reports and procedures for how the faults were resolved were researched and processed. |
