Пристрій для контролю ресурсу комутаційних апаратів

Abstract

The device for tracking resource of switching units comprises current sensors, switching initiation and initiation motion sensors as well as a resource counter, an analog-digital conversion unit where a measured current value is supplied to a memory block, a weight coefficient unit where breaker nonuniformly worked-out resource is calculated at the switching moment, switching time accounting unit, a synchronization unit.
