diplomsko delo visokošolskega strokovnega študijskega programa
Abstract
Cilj diplomske naloge je predstaviti problem in predlagati rešitev za obstoječe zračne odklopnike na srednjenapetostnem 6,3 kV nivoju v NEK, ki se jim izteka življenjska doba. V prvem delu naloge je opisana 6,3 kV lastna raba NEK, s poudarkom in izračunom kratkostičnih razmer za 6,3 kV električno postrojenje MD1 ter predstavljena problematika trenutno vgrajenih zračnih 6,3 kV odklopnikov. Nadalje sta v nalogi obravnavani dve, danes najpogostejši tehnologiji za izdelavo odklopnikov. Na srednjenapetostnem nivoju prevladujejo vakuumski odklopniki, medtem ko SF6 odklopniki predstavljajo le do 5 % vseh odklopnikov. V zadnjem delu naloge so predstavljene stikalne prenapetosti ter povzetek prenapetostne analize ob uporabi vakuumskih odklopnikov. Ob koncu je podana rešitev in predlog vrste izbire novih odklopnikov.

Secondary title: |
Replacment of air circuit breakers with vacuum circuit breakers on 6,3 kV level in Krško nuclear power plant |
Secondary abstract: |
The goal of this diploma work was suggesting the solutions to the problem of existing air circuit breakers owing to their expiry of service life on 6,3 kV Krško NPP level. The first part deals with 6,3 kV on-site supply emphasizing the calculation of short-circuit condition in 6,3 kV switchgear MD1 and with currently installed 6,3 kV air circuit breakers. The central part of diploma sheds light on the two most widely used manufacturing techniques of these breakers. Vacuum circuit breakers prevail among medium-voltage ones, while SF6 circuit breakers only present up to 5 % of them. The last part focuses on switching overvoltages and a summary of overvoltage analysis of the use of vacuum circuit breakers. At the end there is a solution for a new breakers. |
