Пристрій для контролю ресурсу комутаційних апаратів

Abstract

The device for tracking resource of switching units comprises a current and switching sensor, electrical and mechanical resource counters, an analog-digital conversion unit, a weight coefficient unit where breaker nonuniformly breaker worked-out resource is calculated at the switching moment, including taking accounting the last for closed-circuit fault in electrical network, switching time accounting unit, a synchronization unit.
