Low Loss Current Interrupter for Megampere Charging of Inductive Storage

Abstract

A high current, explosively operated slow (2 ms) opening switch has been developed for use as a first stage switch in multi stage switching of inductive storage systems. This switch eliminates the need to use large numbers (20-25 switches/megampere) of more expensive switches in inductive storage pulsed power systems where tens to hundreds of kilovolts are developed during switching of the inductive store. Switch operating parameters include current density to 20 kA/cm 2 , opening time after explosive detonation of 100 clear time of 2 msec to produce a 6 em gap, and voltage holdoff to 100 kV/gap (8-10 kV/cm). System innovations, including the use of a fiber optic coupled detonator firing set, simplify switch use in pulse power systems.
