20.500.12556/DKUM-17116 CASSIE-JEV IN MAYR-JEV MODEL ELEKTRIČNEGA OBLOKA ZA ODKLOPNIKE V PROGRAMSKEM ORODJU MATLAB CASSIE AND MAYR ARC MODELS FOR CIRCUIT BREAKERS IN THE MATLAB PROGRAM TOOL V diplomsko delo je v osnovi zajeta predstavitev visokonapetostnega odklopnika ter njegov pomen v elektroenergetskem omrežju. Predstavljeni so električni stikalni aparati in njihovo delovanje. Večji poudarek je namenjen električnemu obloku, kjer je predstavljen Cassie-jev in Mayr-jev model za analitično določanje parametrov električnega obloka. S Cassie-jevim in Mayr-jevim simulacijskim modelom električnega obloka, ki sta del programskega orodja Matlab, je izvedena simulacija prekinitve električnega toka.Izvedena pa je tudi dopolnitev omenjenih modelov s simulacijo vžigne napetosti. The basis of this diploma paper presents high voltage circuit breaker and its importance in electricity network. Electric switchgears and their functions are introduced in the paper. More focus was put on electric arc. Cassie’s and Mayr’s electric arc the two simulation models for analytical determining of electric arc parameters, which were introduced in this paper. By means of these two simulation models, which are a part of the Matlab program tool, a simulation of breaking electric circuit was carried out. A completion of the above mentioned models through ignition voltage simulation was also carried out. elektrotehnika odklopnik električni oblok matematični model Matlab. electro-technology circuit breaker electric arc mathematical model Matlab. true true false [G.
