Abstract

A control system for at least one vacuum interrupter gap in a high-voltage switching device includes at least one non-reactive control resistor disposed in parallel with the vacuum interrupter. The non-reactive control resistor merges concentrically onto the vacuum interrupter chamber and is mechanically and electrically coupled thereto.

Claims (35)

1. In a vacuum interrupter chamber having at least one vacuum interrupter gap, a control system comprising:

at least one non-reactive control resistor disposed in parallel with the vacuum interrupter gap, said at least one non-reactive control resistor merging concentrically onto the vacuum interrupter chamber and being mechanically and electrically coupled to the vacuum interrupter chamber for interrupting voltages above 1,000 volts.

2. The control system according to claim 1 , further comprising an auxiliary contact gap connected in series with the vacuum interrupter gap.

3. The control system according to claim 1 , further comprising a disconnection/load disconnection contact gap connected in series with the vacuum interrupter gap.
