20.500.12556/DKUM-20669 EKONOMSKA ANALIZA ENOPOLNEGA SN IZOLIRANEGA PODNOŽJA VAROVALK VOH 01 ECONOMIC ANALYSIS OF SINGLE-POLE MV INSULATED FUSE BASE VOH 01 Zaščita distribucijskih transformatorjev je najpogosteje izvedena s pomočjo taljivih varovalk. Dosedanja podnožja in varovalke niso izolirane, kar predstavlja šibko točko transformatorske postaje. V diplomskem delu so predstavljene osnovne značilnosti uporabe enopolnih SN izoliranih podnožij varovalk VOH 01 in rešitev. V ekonomski analizi je opisana upravičenost podražitve zaščite transformatorja ter koristi za kupca in proizvajalca teh podnožij. Izvedena je tudi analiza praga pokritja z izračunom praga pokritja stroškov in izračunom ciljnega dobička. Protection of distribution transformers is often achieved through melting fuses. So far made bases and fuses are not isolated, what represents the weak point of transformer station. Solution and basic characteristics of usage of single-pole MV insulated fuse bases VOH 01 are presented in this graduate paper. Justification of price increase of transformer protection and benefits for customers and manufacturers of those fuses are described in the economic analysis. Analysis of break-even point with calculation of break-even point of costs and calculation of target profit was also carried out. ekonomska analiza podnožje varovalke zaščita transformator taljiva varovalka strošek prag pokritja economic analysis fuse base protection transformator melting fuse cost break-even point true true false [M.
