Abstract
A high voltage, preferably 35 kV, rubber molded fused vacuum interrupter assembly for protecting an electrical circuit from fault currents. The assembly includes one or more vacuum fault interrupters; one or more current limiting fuses; one or more sensing modules and a control module. Each of the vacuum fault interrupters is contained in a molded insulating structure and each of the current limiting fuses is encapsulated in a rubber molding. For each phase of the electrical circuit, a vacuum fault interrupter and a current limiting fuse are connected in series. The sensing modules measure the current in the lines. The vacuum fault interrupter interrupts low current faults and the fuse operates to protect against high current faults in a high voltage electrical power line. A three-phase electrical circuit would have three vacuum fault interrupters and three current limiting fuses.
