Abstract
This invention provides a supersonic expulsion fuse for interrupting fault currents in high voltage alternating current networks. It creates an arc interruption region with a long length of supersonic turbulent flow and little or no subsonic plasma. This increases the arc interrupting capability against both thermal and dielectric arc reignitions. Therefore, the transient recovery voltage the network applies across the interrupted arc after current-zero may be increased in both frequency and peak values, relative to present-art expulsion fuses. It may be applied on power distribution systems as a power fuse in enclosures or overhead where the said system transient recovery voltages exceed the capabilities of conventional distribution cutouts.
