Abstract
Istekom životnog vijeka opreme električnih postrojenja te razvojem novih tehnologija dolazi do zamjene stare opreme novom. U tu svrhu događa se zamjena starih pneumatskih prekidača novim SF6 prekidačima u 220 kV postrojenju termoelektrane Rijeka. Kako bi se bolje shvatio razlog zamjene prekidača, dana je usporedba pneumatskih i SF6 prekidača, njihovi principi rada, prednosti i nedostaci. Također je dan i opis postrojenja te njegova jednopolna shema i dispozicijski nacrt. Kako bi prekidač u svim uvjetima omogućio prekidanje struje kvara potrebno je provesti proračune koji dokazuju da zadovoljava najgore moguće uvjete koji se mogu pojaviti tijekom kvara. U tu svrhu je dan proračun 220 kV SF6 prekidača. Napravljen je proračun prekidne i termičke struje prekidača, proračun utjecaja sila uslijed vlastite težine vodiča, uslijed vjetra i primjer proračuna zatezne sile vodiča. Na kraju je dan opis postrojenja kao takav koji će biti pušten u pogon nakon završetka radova.
Abstract (english)
With expiration of equipment's lifetime electronic switchyards and development of new tehnologies it comes to replacing old equipment with new one. In that purpose, replacement of old air blast circuit breaker with new SF6 circuit breaker is taking place in 220 kV switchyard thermal power plant Rijeka. For better understanding purpose of circuit breaker replacement, there is comparation of air blast and SF6 circuit breakers, their principles, advantages and shortcomings. It's also given description of switchyard and it single line diagram and dispositional draft. For circuit breaker in all conditions to be able to stop interrupting current failure it's needed to conduct calculations that proves lowest possible condutions which can show up during short circuit. In that purpose it's given calculation 220 kV SF6 circuit breakers. It's been made calculation for breaking and thermal current circuit breaker, calculation of influencing forces due to own weight of conductor, due to wind and example calculation of tensile force of circuit breaker during the time of short circuit. At the end it's been given description of switchyard that will be put in operation after refurbishement.
