Realizace měřícího pracoviště pro měření životnosti kontaktů nn

Abstract

The objective of this bachelor work is lifetime and reliability of electric contact. There is an accentuate on lifetime and reliability of electric contact in the present, efforts are concerned to reach best properties of contact, for example by developing better materials for contacts. In this work, I am examining preferably influence of electric current on electric contacts and considering their mechanical and chemical degradation, which is playing important role as well. Chemical degradation, in the frame of this work, is concerned mainly into outer influences as temperature of environment and atmospherically influences acting on contact. In the conclusion of the work is described measurement I have done on set up for contact gripping in laboratory of Vysoka Skola Banska – Technical University of Ostrava.
