Določitev temperaturnega korekcijskega faktorja pri nizkonapetostnih talilnih varovalkah

KOS, URBAN (author), Vončina, Danijel (mentor)

Namen diplomske naloge je praktična potrditev izračuna temperaturnega korekcijskega faktorja s pomočjo meritev. Ta je pomemben podatek pri nizkonapetostnih talilnih vložkih (NV). Delo je bilo opravljeno na podlagi potrebe razvojnega oddelka ETI Elektroelement Izlake, zaradi pridobitve podatkov, ki se bodo navedli v prodajnem katalogu. Diplomska naloga vsebuje opis sestave in delovanja talilnega vložka. Zajet je kratek opis evropskega (IEC) in ameriškega (UL) standarda. Predstavljene so določene točke standarda, ki sem jih uporabil pri meritvah in razlike med obema standardoma v delu, ki se navezuje na mojo nalogo. Opisana je izdelava talilnih vložkov, ki so bili potrebni za merjenje temperatur, ki so se uporabile pri izračunu temperaturnega korekcijskega faktorja. Prav tako pa so predstavljeni vsi ostali izračuni korekcijskih faktorjev. Naveden je tudi opis strojne in programske opreme, ki sem jo uporabljal pri izvajanju meritev. V zadnjem poglavju so predstavljeni rezultati meritev za določeno vrsto talilnih vložkov. Rezultati ostalih meritev so priloženi v prilogi.

Abstract

The purpose of the graduation thesis is to confirm the calculation of the temperature correction factor with the help of measurement for the low melting inputs (NV). The work was based on the needs of the development department of the EIT Elektroelement Izlake, due to acquisition of data, which will be listed in the sales catalog. Graduation thesis consists of a description of the composition and functioning of the melt cartridge. Included is a brief description of the European (IEC) and the American (UL) standard. Presented are certain points of the standard, which I used in the measurements and the differences between the two standards in the parts that relate to my task. The manufacture of a melting cartridges, which were necessary for the measurement of temperatures, which have been used in the calculation of the temperature correction factor is described. All calculations of the correction factors are presented. There is also a description of the hardware and software that I've used in the implementation of the measurement. In the last chapter the results obtained for a particular characteristic of melting cartridges are presented. The results of the other measurements are included in the annex.

• Keywords: Correction (derating) factor, a melting of the insole, IEC and UL standard.
