REALIZATION OF MEASURING AND TESTING IN HIGH VOLTAGE SWITCHING SUBSTATION

V diplomski nalogi so podrobneje opisani stikalni aparati, kosovni preskusi in meritve, ki se na teh aparatih izvajajo. S temi preskusi se razkrivajo napake pri stikalnih aparatih in morajo biti narejeni tako, da je stikalna naprava brezhibna. Obravnavana je rekonstrukcija in delovanje 110 kV stikališča na območju HE Dravograd. Izvedeni so izračuni kratkih stikov s pomočjo katerih je dimenzionirana oprema to so ločilniki, odklopniki in zbiralke. Izračuni kratkih stikov so pokazali, da je izbrana oprema dejansko vgrajena na stikalušču HE Dravograd.The switching devices, routine tests and the measurements to be carried out on these devices are presented in detail in this diploma paper. Errors are revealed by these tests which must be carried out in such a way that the switching device is flawless. The reconstruction and operation of the 110 kV switching substitation in the area of the HE Dravograd is discussed. The calculations of short circuits are carried out and used to help dimension the equipment, such as disconnectors, circuit breakers and busbars. The calculations of short circuits have shown that the selected equipment is actually installed at the switching substation of the HE Dravograd
