Standardizacija vpetja hladilnih enot na stranico kotla transformatorja

Sterle, Klemen (author), Nagode, Marko (mentor), Oman, Simon (comentor)

Podjetje želi standardizirati izbiro izvedbe spoja hladilne enote na steno transformatorskega kotla, saj je to eno izmed trdnostno kritičnih mest. V uporabi je veliko število geometrijsko različnih hladilnih enot, ki različno obremenjujejo izvedbe spoja. Zato izdelamo program, ki bo vrnil informacijo o primernosti izvedbe spoja za poljubno geometrijo hladilne enote. Omejimo se le na standardizacijo iz vidika trdnosti. Konstrukcijo analiziramo po metodi končnih elementov za dve vrsti obremenitve – obremenitev lastne teže in superponirane potresne obremenitve, določene po standardu Evrokod 8.

• Title: Standardization of a cooling unit mounting on the power transformer tank

Abstract

Company wants to standardize process of choosing a mechanically critical subassembly – connection between cooling unit and wall of the power transformer tank. Loading of mentioned connection depends on geometry of cooling units. Geometries in use have large variety, therefore we develop a program which returns information of appropriateness of connection type for specified loading – cooling unit geometry. Connection assembly is analysed by finite element analysis, considering standard earth gravity and superposed earthquake loading, defined by Evrokod 8.
