Abstract:
Short pulses of high energy are generated at a high-pulse rate by providing high energy from an acyclic generator having a plurality of discs rotating in the field of a superconductive field coil and commutating the output of the generator, through an electric discharge device connected across the same, by means of a pair of oppositely poled, sequentially operated triggerable vacuum arc devices.
Abstract:
This disclosure relates to a ''''keep-alive'''' circuit for a triggered vacuum gap wherein the duration of the usual trigger pulse is insufficiently long to maintain the vacuum gap in an active state for more than one-half cycle at the powerline frequency. A circuit utilizing current transformers is described wherein a current transformer provides the trigger pulse necessary to maintain the vacuum gap in an active state for as long as necessary to protect electrical equipment shunted by the vacuum gap.
