dc.description.abstractCilj ovog rada je ispitivanje uticaja oblika magnetnog polja u međukontaktnom prostoru u smislu degradacije kontakata tokom sklopnih operacija isklopa pod opterećenjem. U tom smislu statistički su analizirani rezultati merenja naizmeničnog probojnog napona i impulsnog probojnog napona. Eksperimenti su sprovedeni na komercijalnim prekidačima sa CuCr kontaktima. Parametri u eksperimentu bili su vrednost napona prilikom prekidanja struje i međukontaktno rastojanje. Ustanovljeno je da prekidači sa radijalnim magnetnim poljem u međukontaktnom prostoru trpe manje ireverzibilne promene tokom prekidanja nominalne struje i nominalne struje kratkog spoja.sr
dc.description.abstractThe aim of this paper is to examine the influence of the magnetic field shape in the inter-contact space in the context of contact degradation during the switching operation of circuit-breaking with current. The results of measuring the AC breakdown voltage and pulse breakdown voltage are statistically analyzed for that purpose. The experiments are carried out on the commercial switching elements with CuCr contact. The experiment parameters are the current breaking voltage value and inter-electrode distance. Results showed that switches with radial magnetic field suffer less irreversible changes during the breaking operation such as circuit-breaking with nominal current and circuit-breaking with short-circuit current.en
