Abstract

It is shown, that when choosing materials for the contacts of the vacuum arc-quenching chamber of the synchronous vacuum contactor, it is necessary to take into account operation conditions of the contacts, which take place during synchronous switching off, namely: wear reduction of the contacts and limiting of switching overvoltages.
