Air Gap Switch for Crowbering

Abstract

A new type of air gop switch for crowbering is reported.It consists of two main electrodes between which two sheets of trigger electrodes with a hole in its centre are inserted.Trigger electrodes. are clssely spaced each other sandwitching a insulating plastic ring. When a rapid sising over volted triger pulse is applied, break-downs occur symmetrically in both gaps between main and trigger electrodes, which enables satis factoryly crowbering characteristics.
