Electric control distance-adjusting type gas spark switch used for electromagnetic pulse simulator

Abstract

The invention discloses an electric control distance-adjusting type gas spark switch used for an electromagnetic pulse simulator, and belongs to the pulse power device technology field. During the use, a power switch is closed, and an electromagnetic coil is electrified to generate electromagnetic force, and is used to drive an electromagnetic core to move a compression spring upwards, and thereafter an insulation rod is used to drive a trigger electrode to move upwards, and a trigger gap between an input electrode and an output electrode is reduced for triggering, and therefore an input end and an output end are conducted. The power switch is disconnected, and the electromagnetic coil is not electrified, and the electromagnetic force disappears, and then the electromagnetic core moves downwards under the action of the elastic force of the compression spring, and therefore the insulation rod is used to drive the trigger electrode to move downwards, and the trigger gap between the input electrode and the output electrode is increased, and therefore the input end and the output end are disconnected. The electric control distance-adjusting type gas spark switch is advantageous in that the structure is simple, and the operation is convenient; an ability of bearing high voltage and high air pressure is strong; good sealing performance and good shielding performance are provided; pulse source rising time is reduced, and the immunity to external interferences of the switch is enhanced, and therefore waveform quality is improved.

Description

technical field [0001] The invention relates to a gas spark switch for an electromagnetic pulse simulator, in particular to an electrically controlled distance-adjustable gas spark switch for an electromagnetic pulse simulator, and belongs to the technical field of pulse power devices. Background technique [0002] With the rapid development of pulse power technology, switches, as an important part of pulse power systems, have attracted widespread attention from researchers and the public.
