Possibility of Application of Multilayer Condensed Muliticomponent Material in Electrical Contacts of LV Vacuum Interrupters

摘要

Paper presents and discusses investigated results of performance of selected low voltage vacuum interrupters in which the multicomponent multilayer condensed contact material based on Cu-W compositions was employed.On the basis of the switching test results followed by respective inspections of the contacts surface and investigations of the microanalysis as well as material morphology the conclusions on possibility of application of such the material composition for LV vacuum interrupters in practice are formulated.
