Пристрій для контролю ресурсу комутаційних апаратів

Abstract

The device for tracking of switching unit resource comprises a current sensor in itself is used as a shunt, a switching start sensor as well as a resource and mechanical counter, an analog-digital conversion unit wherein measured current value through an opto relay decoupling is supplied to a store unit, a weight coefficient unit wherein where nonuniformly worked-out break resource is calculated at the moment of switching including with account of switching on the last for short-circuit in the electrical network, switching time evaluator, a synchronization unit.
