Пристрій для контролю ресурсу повітряних високовольтних вимикачів

Abstract

The device for tracking of air high-voltage circuit-breaker resource comprises current, pressure and switching sensors as well as resource and mechanical counters, an analog-digital conversion unit, a weight coefficient unit 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.
