The device for tracking resource of air high-voltage circuit-breakers comprises a current, pressure and switching sensor as well as a resource counter, an analog-digital conversion unit, a time switching accounting unit, a linearization module. At the moment of current flow through a breaker, this current value as well as compressed air pressure is stored and transferred to switching-off a rated operational current. In the resource counter deprecation of this breaker is accounted at the switching moment. |
