20.500.12556/DKUM-36931 MENJAVA MALOOLJNIH ODKLOPNIKOV Z VAKUUMSKIMI REPLACEMENT OF MINIMUM OIL CIRCUIT BREAKER WITH VACUUM CIRCUIT BREAKER Cilj diplomske naloge je predstaviti problem in predlagati rešitev za obstoječe malooljne odklopnike na srednjenapetostnem 6 kV nivoju, ki se jim izteka življenjska doba. V nalogi je opisana 6 kV lastna raba s poudarkom izvedbe protieksplozijskega zaščite elektro naprav. V nadaljevanju je opisana določena protieksplozijska zaščita elektro naprave, v kateri se nahaja odklopnik, opis obeh izvedb odklopnikov v tem primeru ter nastanek in gašenje električnega obloka, menjava odklopnikov (izračuni, razmere, pojavi ter razlaga za zamenjavo odklopnikov). Ob koncu je podana rešitev in predlog vrste izbire novih odklopnikov. The aim of the thesis is to present the problem and to propose solutions to existing medium voltage minimum oil circuit breakers at 6kV level, which are close to the expiry date. The task is to describe 6 kV own use with the emphasis of performance explosion protection electrical equipment. In the following description of certain electrical explosion protection devices which are located in the breaker, a circuit description of the two performances in this case and the emergence and extinction of electric arc, switching circuit (calculations, the situation occurs and the explanation for the replacement of circuit breakers) are presented. At the end, there is a solution and a proposal selection of new types of circuit breakers presented.
