Abstract
The invention provides a vacuum interrupter with improved separation of functional elements. The interrupter includes separable contacts for carrying continuous current and rod electrode arrays for carrying fault currents. The housing for the interrupter is evacuated, and has a plurality of interior chambers. The rod electrodes are in one chamber and the separable contacts are in an adjacent chamber. A communicating opening is provided between the chambers. The rod electrodes and separable contacts are connected in parallel in a common circuit. When the contacts are separated, arcing products are conveyed to the adjacent chamber through the communicating opening to initiate arcing between the rod electrodes.
