A device for monitoring resource of air high-voltage switches comprises sensors of current, pressure and switching, as well as resource counters, unit of analog-digital conversion measuring current amplitude at output of current sensor , unit for determination of switching time. At the moment of current flow through switch the value of current and compressed air pressure is stored. In the resource counters the switch operation resource at the moment of switching is accounted pole by pole. |
