A device for controlling life of high-voltage air circuit breakers comprises a current probe, pressure and switching sensors as well as a life and mechanical counters, an analog-to-digital conversion unit, a linearization module, a switching time detection unit, a synchronization unit. At the moment of current flow through the circuit breaker the value of this current as well as a value of the compressed air pressure are stored. In the life and mechanical counters actuation of the breaker at the moment of commutation is accounted. |
