Пристрій для контролю ресурсу повітряних високовольтних вимикачів

Abstract

The device for tracking resource of air high-voltage circuit-breakers comprises a current, pressure, switching sensor as well as a resource and mechanical counter, an analog-digital conversion unit, a weight coefficient unit where air high-voltage circuit-breaker nonuniformly worked-out resource is calculated at the switching moment which includes taking account switching-on the last for closed-circuit fault in electrical network, a switching time accounting unit, a synchronization unit. The device allows checking on break switching resource taking into account their on/off-time.
