Razvoj podpornih elementov energetskega transformatorja za dvigovanje s hidravličnimi dvigalkami

Seliškar, Blaž (author), Vukašinović, Nikola (mentor)

Energetski transformatorji so pomemben del elektroenergetskega omrežja. Za njihovo dviganje in premike so opore za dvig ključnega pomena. Dimenzije opor so odvisne od več faktorjev in zahtev. Z primerno geometrijo lahko poskrbimo, da bodo opore zdržale obremenitve med uporabo. Na podlagi analize hidravličnih dvigalk na trgu ter izdelani statistiki preteklih projektov smo določili pomembne geometrijske parametre opor za dvig in jih razvrstili v obremenitvene razrede. Za vse kombinacije geometrije smo izvedli statične trdnostne analize in določili primerne rešitve. Na podlagi rezultatov smo izdelali ekspertni sistem, ki omogoča uporabniku hitro določitev parametrov geometrije opore za poljuben transformator.

• Title: Development of power transformer support elements for lifting with hydraulic jacks

Abstract

Power transformers are an important part of the power grid. For their manipulation during transport the lifting supports are essential. The geometry of the supports depends on several factors and requirements. With the right geometry, we can ascertain that supports can withstand the lodas during use. Based on the analysis of hydraulic jacks on the market and the statistics of past projects, we determined important geometric factors for lifting supports and distributed them in load classes. We performed static structural analysis for all geometry combinations and determined a suitable solution. Based on the results, we created an expert system that allows the user to quickly determine the parameters of the support geometry for any transformer.
