Пристрій для контролю ресурсу групи комутаційних апаратів

Abstract

A device for monitoring resource of switching unit comprises sensors of current and switching, as well as counters of electric resource per each phase of each switch, unit of analog-digital conversion, linearization unit, weighting factor unit wherein irregularly worked-out resource of switch group is calculated at switching moment, synchronization unit. When closing of switch the moment of current flow beginning through one of poles is recorded as reference time, and switching time delay of other poles is measured beginning from this moment, and if it is excessive a signal is occurred at corresponding device outputs.
