Dielectric Recovering Ability Analysis of Electro-magnetic Repulsion Actuator Piston High-Speed Isolator

Aiming at the existing problems of explosive piston high-speed isolator, this paper proposes electro-magnetic repulsion actuator piston high-speed isolator based on electro-magnetic repulsion principle. In order to optimize the media recovering ability of high-speed isolator, we bring in torus grid and quartz sand into isolator referred by the Richhardson and Saha equation. A compulsory exchange current dielectric recovering circuit is designed and we conduct an optimized experiment. The results show that this isolator can improve media recovering ability.
