INVESTIGATION OF HIGH-CURRENT INTERRUPTING CONTACTS WORKING SURFACES MECHANICAL INTERACTION NATURE

Introduction. The nature of the interaction of high-working surfaces of the electrical contact uniquely affects their performance. By the failure of the contacts in the main drive processes resulting from complex destructive factors affecting their performance. However, not all processes are studied...
