Investigation of Feasibility of Vacuum-Arc Fault-Current Limiting Device

摘要

The feasibility of a vacuum arc fault current limiter was investigated in this project. This work is an outgrowth of the studies on the interruption of dc vacuum arcs that have been underway at the State University of New York at Buffalo (SUNYAB) for several years. In those studies a magnetic field has been used to interrupt or control the current flow in a vacuum arc device. The configuration of the device is such that electron current is forced to flow primarily radially outward from the end of a relatively small rod shaped cathode to a ring shaped anode. Control is achieved through the application of an axial magnetic field.
