Пристрій для контролю ресурсу комутаційних апаратів

Abstract

A device for controlling life of switching units comprises a current probe and switching sensor as well as a life and mechanical counters, an analog-to-digital conversion unit, a weight unit wherein switching unit irregularly worked-out service life at the moment of commutation is computed with account of fault close-in of the latter, a switching time detection block, a synchronizer.
