Alternating current circuit breakers

U ovom završnom radu predstavljeni su sklopni aparati, te oni koji se od njih koriste za prekidanje izmjenične struje. Svaki je predstavljen detaljno, te je objašnjen princip djelovanja i sve vrste. Predstavljen je i električni luk kao posljedica isklapanja strujnog kruga, načini suzbijanja luka i neke njegove korisne primjene U uvodu su predstavljeni sklopni aparati, općeniti podaci o njima i neke njihove primjene. Zatim smo se upoznali s vrstama sklopnih aparata koji služe za prekidanje izmjenične struje. Dotakli smo se i proučili svakog od njih, njegove primjene, osobine, područja djelovanja, vrste i građu. Nadalje, predstavljena je i posljedica prekidanja izmjenične struje, električni luk. Objašnjen je njegov kemijski i fizički uzrok i nastanak, te načini na koji ga pokušavamo suzbiti. Na samom kraju, upoznali smo se i s nekim korisnim primjenama električnog luka i naglasili istraživanja koja žele otkriti još mnoge takve primjene.This work presents the switchgears, and those used to switch off the alternating current. Each is presented in detail, and it is precisely explained how every one of them works. An electric arc was also introduced as a result of the circuit break-off, also the ways of controlling the arc and some of its useful applications The introduction contains a short insight in the switchgears in general, some information about them and their applications. Division of switchgears into types is presented and then we met with certain types of switching devices that serve to interrupt AC. We have also studied each and every one of them, their applications, traits, areas of action, types and materials. Furthermore, electric arc is also presented as a result of interruption of AC. Its chemical and physical cause and origin, and the ways in which we try to suppress it are presented. We also met some of the useful applications of the electric arc and emphasized the research that they want to discover yet many such applications. . At the very end, the huge importance of this type of research is explained
