Abstract
Tema ovoga rada su visokonaposnki prekidači kao element zaštite u električnim postrojenjima. Na početku rada definiran je pojam kratkog spoja i izložene su vrste kratkih spojeva. Posebno su opisane vrijednosti struja kratkog spoja. Zatim je dana definicija prekidača, te opisana podjela istih s obzirom na različite karakteristike. Također su navedeni i opisani sastavni dijelovi prekidača. Objašnjen je električni luk, njegovo nastajanje, prekidanje, te način spriječavanja njegovog ponovnog paljenja. Nadalje su posebno prikazane vrste prekidača s obzirom na medij gašenja. Uz navedeno, rad se bavi i pitanjem izbora prekidača. ispitivanjem samih prekidača i održavanjem istih, pa je stoga izložen tijek naprijed navedenih postupaka. U zadnjem dijelu rada prikazan je praktični primjer primjene prekidača u TS Tušmer.
Abstract (english)
The subject of this paper are high voltage circuit breakers as an element of protection in electrical plants. The first chapter contains definition of short circuit and the types of short circuit. The short circuit current values are specially described. Then, high voltage circuit breakers are defined, and their division is described with regard to different characteristics. The parts that circuit breakers are made of are also listed and described. An electric arc is explained, its ignition, interruption, and the way to prevent its reignition. Furthermore, the types of circuit breakers are shown sparatley with regard to the arch quenching medium. This paper discusses question of electing circuit breakers, testing and maintaining them, therefore course of procedures mentioned above is exposed. Paper is conlcuded by practical application of circuit breakers in electrical plant Tušmer.
