Abstract
Ispitivanje na unutarnji luk metalom oklopljenog, plinom SF6 izoliranog sklopnog postrojenja nazivnog napona 145 kV definirano je u normi za visokonaponske oklopljene sklopne aparate, IEC 62271-203 koja spada u grupu neobaveznih tipskih ispitivanja. U radu je dan opis matematičkih modela koji služe za izrađu računalnih simulacija kojima se analizira unutarnji luk te je odabran unaprijeđeni osnovni model koji, osim zadovoljavajuće točnosti proračuna, ima manje vrijeme proračuna i modeliranja sklopnih aparata od složenijih modela. Nakon teorijskog osvrta, dan je opis izrađenog programskog sučelja i analizirana njegova točnost na provedenim ispitivanjima. Zaključeno je da razvijeni program daje dovoljno točan proračun vremenske promjene parametara koji opisuju unutarnji luk, te istaknuti ključni parametri na koje se pri simulaciji mora paziti kako bi ona bila reprezentativna za stvarne pojave u visokonaponskim sklopnim aparatima.
Abstract (english)
Internal arc testing of metal enclosed, SF6 isolated switchgear rated for 145KV is defined in IEC 62271-203, a norm for highvoltage enclosed switchgear, which is grouped in non-mandatory type tests. In this paper, an explanation is given for mathematical models which are used in making of computer simulations that analyse internal arc, and an enchanced model is picked, which apart from satisfying the accuracy of the calculation, also has less calculating and modeling time for switchgears than the more complex models. After the theoretical review, a description of the created computer interface is given and its accuracy is analyzed on the conducted tests. It is concluded that the developed program provides a sufficiently accurate calculation of the time change of the parameters that describe the internal arc, and key parameters that must be observed during the simulation are highlighted, so that the computer simulation could be representative of the real effects in high-voltage switchgear.
